TVA
began a significant nuclear plant
construction program in 1966 to meet projected system load growth. At
the height of its construction program, TVA had 17 units either under
construction or in commercial operation at seven plant sites. In
1982, TVA canceled construction of four units because of lower than expected
load growth, and TVA canceled four more units in 1984 for similar
reasons.
By
August 1985, TVA had delayed
construction of two units each at Watts Bar and Bellefonte Nuclear Plants and
had shut down its three-unit Browns Ferry Nuclear Plant and two-unit Sequoyah
Nuclear Plant because of an increasing number of technical and operational
problems. The Nuclear Regulatory Commission (“NRC”) required TVA to
address program and management deficiencies and to provide its corrective
actions to the NRC before restarting any of its licensed nuclear units or
requesting a license for Watts Bar Unit 1. After implementing a
comprehensive recovery plan, TVA restarted Sequoyah Unit 2 in May 1988 and
Sequoyah Unit 1 in November 1988. TVA restarted Browns Ferry Unit 2
in May 1991 and Browns Ferry Unit 3 in November 1995. Construction of
Watts Bar Unit 1 was successfully completed, and the unit commenced full power
commercial operation in May 1996.
In
May 2002, the TVA Board initiated
activities to return Browns Ferry Unit 1 to service, and on August 1, 2007,
Browns Ferry Unit 1 returned to commercial operation. The total
amount invested in the Unit 1 restart project through the commercial operation
date was $1.84 billion excluding allowance for funds used during construction
(“AFUDC”) of $269 million. TVA completed Browns Ferry Unit 1 during
2007 with a total project cost overrun of $90 million or five percent of the
original projected cost. The cost overruns were due in part
to the scope of work associated with extended power uprate being
greater than planned. Browns Ferry Unit 1 provides additional
generating capacity of approximately 1,150 megawatts and is expected to
eventually provide 1,280 megawatts of capacity.
In
November 2005, TVA canceled the
construction of Units 1 and 2 at Bellefonte Nuclear Plant. Two months
prior to the cancellation of these units, the Bellefonte site was selected
by
NuStart Development LLC (“NuStart”) as one of two sites for the development of a
combined license application for two new reactors using the Westinghouse
Advanced Passive 1000 (“AP1000”) reactor design. NuStart is an
industry consortium composed of 10 utilities and two reactor vendors whose
purpose is to satisfactorily demonstrate the new NRC licensing process for
advanced design nuclear plants. TVA submitted its combined license
application to the NRC for Bellefonte Units 3 and 4 in October
2007. If approved, the license to build and operate the plant would
be issued to TVA. Obtaining the necessary license will give TVA more
certainty about the cost and schedule of a nuclear option for future
decisions. The TVA Board has not made a decision to construct a new
plant at the Bellefonte site.
On
August 1, 2007, the TVA Board
approved completing the construction of Watts Bar Unit 2. Prior to
the approval, TVA conducted a detailed scoping, estimating, and planning study
to estimate the project’s cost, schedule, and risks. Separately, TVA
prepared a report evaluating potential environmental impacts as required by
the
National Environmental Policy Act. TVA has an NRC construction permit
for Watts Bar Unit 2 that expires in 2010 and will need to seek an extension
of
the permit in order to complete construction activities. TVA will
seek an operating license under NRC regulations, and this process will include
an opportunity for a public hearing. Completing Watts Bar Unit 2 is
expected to take approximately 60 months and cost approximately $2.5 billion,
excluding AFUDC. Preliminary project activities began in October
2007. In accordance with NRC policy, TVA notified the NRC that it may resume
unrestricted construction activities as early as December 3,
2007. Current plans are to begin construction related activities
by the end of December 2007. When completed, Watts Bar Unit 2 is expected
to provide 1,180 megawatts of capacity.
Spent
Nuclear Fuel
Under
the Nuclear Waste Policy Act of
1982, TVA (and other domestic nuclear utility licensees) entered into a contract
with the U.S. Department of Energy (“DOE”) for the disposal of spent nuclear
fuel. Payments to DOE are based upon TVA’s nuclear generation and
charged to nuclear fuel expense. Although the contracts called for
DOE to begin accepting spent nuclear fuel from the utilities by January 31,
1998, DOE announced that it would not begin receiving spent nuclear fuel from
any domestic nuclear utility until 2010 at the earliest. TVA, like
other nuclear utilities, stores spent nuclear fuel in pools of borated water
at
its nuclear sites. TVA would have had sufficient space to continue to
store spent nuclear fuel in those storage pools at its Sequoyah and Browns
Ferry
Nuclear Plants indefinitely had DOE begun accepting spent nuclear
fuel. DOE’s failure to do so in a timely manner required TVA to
construct dry cask storage facilities at its Sequoyah and Browns Ferry Nuclear
Plants and to purchase special storage containers for the spent nuclear
fuel. The Sequoyah and Browns Ferry dry cask storage facilities have
been constructed and approved by the NRC and have been in use since 2004 and
2005, respectively, providing storage capacity through 2030 at Sequoyah and
2019
at Browns Ferry. Watts Bar has sufficient storage capacity in its
spent fuel pool to last until approximately 2015.
To
recover the cost of providing
long-term, on-site storage for spent nuclear fuel, TVA filed a breach of
contract suit against the United States in the Court of Federal Claims in
2001. In August 2006, the United States paid TVA almost
$35 million in damages awarded by the Court of Federal Claims, which
partially offset the construction costs of the dry cask storage facilities
that
TVA incurred through 2004. TVA is pursuing additional claims against
DOE to recover costs that TVA has incurred after 2004.
Low-Level
Radioactive
Waste
Low-level
radioactive waste
(“radwaste”) results from the normal operation of nuclear units and includes
such materials as disposable protective clothing, mops, and
filters. TVA has contracted to dispose of radwaste at a Barnwell,
South Carolina, disposal facility through June 2008. As allowed
by the Low-Level Radioactive Waste Policy Act, on July 1, 2008, the Barnwell,
South Carolina, facility will close to radwaste generators located in states
that are not members of the Atlantic Interstate Low-Level Radioactive Waste
Management Compact ("Atlantic Compact"). Connecticut, New Jersey, and
South Carolina are members of the Atlantic Compact. Accordingly, after
June 2008, TVA will no longer be able to use this disposal facility and
will have to consider other options, which may include storing some radwaste
at
its own facilities. TVA is capable of doing so for an extended period
of time, and has done so in the past.
Nuclear
Decommissioning Trust
TVA
maintains a nuclear decommissioning
trust to provide funding for the ultimate decommissioning of its nuclear power
plants. The trust is invested in securities generally designed to
achieve a return in line with overall equity market performance. The
assets of the trust as of September 30, 2007, totaled $1.1 billion, which is
greater than the present value of TVA’s estimated future nuclear decommissioning
costs as computed under the NRC funding requirements but less than the present
value of these costs as computed under Statement of Financial Accounting
Standards No. 143,
“Accounting for Asset Retirement Obligations.”
See
Note 14 —
Contingencies — Decommissioning Costs.
Nuclear
Insurance
The
Price-Anderson Act provides a
layered framework of protection to compensate for losses arising from a nuclear
event. For the first layer, all NRC nuclear plant licensees,
including TVA, purchase $300 million of nuclear liability insurance from
American Nuclear Insurers for each plant with an operating
license. Funds for the second layer, the Secondary Financial Program,
would come from an assessment of up to $101 million from the licensees of each
of the 104 NRC licensed reactors in the United States. The assessment
for any nuclear accident would be limited to $15 million per year per
unit. American Nuclear Insurers, under a contract with the NRC,
administers the Secondary Financial Program. With its six licensed
units, TVA could be required to pay a maximum of $604 million per nuclear
incident, but it would have to pay no more than $90 million per incident in
any
one year. When the contributions of the nuclear plant licensees are
added to the insurance proceeds of $300 million, over $10.7 billion would be
available. Under the Price-Anderson Act, if the first two layers are
exhausted, Congress is required to take action to provide additional funds
to
cover the additional losses.
TVA
carries property, decommissioning, and decontamination insurance of $4.6 billion
for its licensed nuclear plants, with up to $2.1 billion available for a loss
at
any one site, to cover the cost of stabilizing or shutting down a reactor after
an accident. Some of this insurance, which is purchased from Nuclear
Electric Insurance Limited (“NEIL”), may require the payment of retrospective
premiums up to a maximum of approximately $66 million. On October 1,
2007, TVA endorsed the existing property policies for the Watts Bar Nuclear
Plant site to add Builders Risk coverage for the construction of Unit
2. The addition of this coverage places the new maximum retrospective
assessment at $70.5 million.
TVA
purchases accidental outage
(business interruption) insurance for TVA’s nuclear sites from
NEIL. In the event that an accident covered by this policy takes a
nuclear unit offline or keeps a nuclear unit offline, NEIL will pay TVA, after
a
waiting period, an indemnity (a set dollar amount per week) up to a maximum
indemnity of $490 million per unit. This insurance policy may require
the payment of retrospective premiums up to a maximum of approximately $24
million. See Note 14 —
Contingencies
—
Nuclear
Insurance.
Tritium-Related
Services
TVA
and DOE are engaged in a long-term
interagency agreement under which TVA will, at DOE’s request, irradiate tritium
producing burnable absorber rods to assist DOE in producing
tritium. Tritium is used in nuclear weapons. This
agreement, which ends in 2035, requires DOE to reimburse TVA for the costs
that
TVA incurs in connection with providing irradiation services and to pay TVA
an
irradiation services fee at a specified rate per tritium-producing rod over
the
entire operating cycle in which the tritium-producing rods are
irradiated.
In
September 2002, the NRC issued amendments to the operating licenses for the
Watts Bar and Sequoyah Nuclear Plants, allowing TVA to provide irradiation
services for DOE at these plants. The Watts Bar license amendment
currently permits TVA to install up to 240 tritium-producing rods in Watts
Bar
Unit 1. Planned future license amendments would allow TVA to irradiate up to
approximately 2,000 tritium-producing rods in the Watts Bar and Sequoyah
reactors.
In
general, tritium-producing rods are
irradiated for a full cycle, which lasts about 18 months. At the end
of the cycle, TVA removes the irradiated rods and loads them into a shipping
cask. DOE then ships them to its tritium-extraction
facility. TVA loads a fresh set of tritium-producing rods into the
reactor during each refueling outage. Irradiating the
tritium-producing rods does not affect TVA’s ability to operate the reactors to
produce electricity.
TVA
began irradiating tritium-producing
rods at Watts Bar Unit 1 in the fall of 2003. TVA removed these rods
from the reactor in the spring of 2005. DOE subsequently successfully
shipped them to its tritium-extraction facility. At this time, no
tritium-related services are being performed at the Sequoyah Nuclear
Plant.
General
TVA’s
consumption of various types of
fuel depends largely on the demand for electricity by TVA’s customers, the
availability of various generating units, and the availability and cost of
fuel. The following table indicates TVA’s costs for various fuels for
the years indicated:

Beginning
with the implementation of
the FCA mechanism on October 1, 2006, TVA’s rates are adjusted on a quarterly
basis to reflect changing fuel and purchased power costs. See Item 1,

Rate Actions
.
Coal
Coal
consumption at TVA’s coal-fired
generating facilities during 2007 was 46.5 million tons. As of September 30,
2007 and 2006, TVA had 23 days and 20 days of system-wide coal supply at full
burn, respectively, with a net book value of coal inventory of $264 million
and
$214 million, respectively.
TVA
utilizes both short-term and
long-term coal contracts. Long-term coal contracts generally last
longer than one year, while short-term contracts are usually for one year or
less. During 2007, long-term contracts made up 89 percent of coal
purchases and short-term contracts accounted for the remaining 11
percent. TVA plans to continue signing contracts of various lengths,
terms, and coal quality to meet its expected burn and inventory
requirements. During 2007, TVA purchased coal by basin as
follows:
•
|
37
percent from the Illinois Basin;
|
•
|
24
percent from the Powder River Basin in
Wyoming;
|
•
|
23
percent from the Uinta Basin of Utah and Colorado;
and
|
•
|
16
percent from the Appalachian Basin of Kentucky, Pennsylvania, Tennessee,
Virginia, and West Virginia.
|
Total
system coal inventories were at
or above target levels for all of 2007. During 2007, 42 percent of TVA’s coal
supply was delivered by rail, 19 percent was delivered by barge, and 33 percent
was delivered by a combination of barge and rail. The remainder was delivered
by
truck.
Natural
Gas and Fuel Oil
During
2007, TVA purchased substantially all of its natural gas requirements from
a
variety of suppliers under contracts with terms of one year or
less. TVA purchases substantially all of its natural gas to operate
combustion turbine peaking units and to supply fuel under power purchase
agreements in which TVA is the fuel supplier. At September 30, 2007,
all but one of TVA’s combustion turbine plants were dual fuel capable, and TVA
has fuel oil stored on each site for its dual-fuel combustion turbines as a
backup to natural gas.
During
2007, TVA purchased substantially all of its fuel oil on the spot
market. At September 30, 2007 and 2006, the net book value of TVA’s
natural gas in inventory was $3 million and $2 million, respectively, and the
net book value of TVA’s fuel oil in inventory was $50 million and $54 million,
respectively.
Nuclear
Fuel
Converting
uranium to nuclear fuel
generally involves four stages: the mining and milling of uranium ore
to produce uranium concentrates; the conversion of uranium concentrates to
uranium hexafluoride gas; enrichment of uranium hexafluoride; and the
fabrication of the enriched uranium hexafluoride into usable fuel
assemblies. TVA currently has 100 percent of its forward four-year
(2008 through 2011) uranium mining and milling requirements either in inventory
or under contract for its boiling water reactor units at Browns Ferry Nuclear
Plant and has 100 percent of its forward four-year (2008 through 2011) uranium
requirements under contract for its pressurized water reactor units at Sequoyah
and Watts Bar Nuclear Plants. In addition, TVA has 100 percent of its
conversion, enrichment, and fabrication needs under contract through
2011.
TVA,
DOE, and some nuclear fuel
contractors have entered into agreements that provide for the blending down
of
surplus DOE highly enriched uranium (uranium that is too highly enriched for
use
in a nuclear power plant) with other uranium. Under these agreements,
the enriched uranium that results from this blending process, which is called
blended low enriched uranium (“BLEU”), is fabricated into fuel that can be used
in a nuclear power plant. This blended nuclear fuel was first loaded
in a Browns Ferry reactor in 2005 and is expected to continue to be used to
reload the Browns Ferry reactors through 2013. Plans are underway to
begin using BLEU fuel in Sequoyah Unit 2 beginning in 2008.
Under
the terms of an interagency
agreement between DOE and TVA, in exchange for supplying highly enriched uranium
materials for processing into usable BLEU fuel for TVA, DOE will participate
to
a degree in the savings generated by TVA’s use of this blended nuclear
fuel. TVA anticipates these future payments could begin in 2009 and
last until 2013. See Note 1 —
Blended Low Enriched Uranium
Program
for a more detailed discussion of the BLEU project.
TVA
owns
all nuclear fuel held for its nuclear plants. As of September 30,
2007 and 2006, the net book value of this nuclear fuel was $602 million and
$491
million, respectively.
For
a
discussion of TVA’s plans with respect to spent nuclear fuel storage, see Item
1, Business
— Nuclear — Spent Nuclear Fuel
.
The
TVA transmission system is one of
the largest in North America. The system delivered nearly 175 billion
kilowatt-hours of electricity in 2007, and has operated with 99.999 percent
reliability over the last eight years in delivering electricity to
customers.
To
the extent federal law allows access
to the TVA transmission system, the TVA transmission organization offers
transmission services to others to transmit power at wholesale in a manner
that
is comparable to TVA's own use of the transmission system. TVA has also adopted
and operates in accordance with a published Standards of Conduct for
Transmission Providers and appropriately separates its transmission functions
from its marketing functions.
Also,
TVA is cooperating with other
transmission systems to improve regional coordination in the operation of the
bulk transmission system. The initial step of this coordination
effort was to establish a joint transmission reliability area with other public
power systems. In 2002, TVA entered into reliability coordination
agreements with Associated Electric Cooperative Inc., Big Rivers Electric
Corporation, and East Kentucky Power Cooperative, Inc. In 2004,
Electric Energy, Inc., joined this effort, and in 2006, TVA began providing
reliability coordination services for E.ON U.S. subsidiaries Kentucky Utilities
Company and Louisville Gas and Electric Company.
Consistent
with these arrangements, TVA
has been designated by the North American Electric Reliability Corporation
(“NERC”) to serve as the reliability coordinator for parts of 11 states covering
199,000 square miles with a population of nearly 11 million
people. As the reliability coordinator for this region, TVA is
responsible for monitoring and helping to ensure the reliable operation of
the
bulk transmission system in a region that includes portions of Alabama, Georgia,
Illinois, Iowa, Kentucky, Mississippi, Missouri, North Carolina, Oklahoma,
Tennessee, and Virginia. TVA is one of 17 reliability coordinators in
NERC.
Additionally,
TVA, in its capacity as
reliability coordinator, has executed a joint reliability coordination agreement
with the Midwest Independent Transmission System Operator and PJM
Interconnection, LLC to improve the reliability of the regional
grid. This effort includes a coordinated approach to transmission
capacity availability, system outage approval, congestion management, and
transmission planning. Similar agreements to coordinate analysis and
operational processes in support of regional transmission reliability have
been
executed with Entergy Services, Inc., Southwest Power Pool, Inc., Southern
Company Services, Inc., and VACAR South RC (a Virginia Carolina reliability
group).
Reliability
Coordinator Map
A
new interconnection, the Five Points
- Homewood project, was completed to address several contingency issues in
the
southern extreme of TVA's Mississippi service area. This interconnection with
South Mississippi Electric Power Association is the first with a neighboring
utility since 1993. TVA now has interconnections with 13 neighboring
electric systems.
Mandatory
compliance with certain
reliability standards began on June 18, 2007. FERC issued its final
rule on the Electric Reliability Organization (“ERO”) Reliability Standards,
approving 83 of 107 proposed standards submitted by the North American Electric
Reliability Corporation. The mandatory reliability standards apply to
all users, owners, and operators of the bulk power system, including TVA, and
both monetary and non-monetary penalties may be imposed for violations of the
standards. The most serious violations can be subject to penalties of up to
$1
million per day per violation. The rule directs the ERO to focus on the most
serious violations during an initial period through December 31,
2007. To the best of its knowledge, TVA is operating in conformity
with these reliability standards.
TVA
is responsible for
managing the Tennessee River and its tributaries – the United States’
fifth largest river system – to provide, among other things, year-round
navigation, flood damage reduction, affordable and reliable electricity, and,
consistent with these primary purposes, recreational opportunities, adequate
water supply, improved water quality, and economic development. TVA
operates 49 dams, which comprise its integrated reservoir
system. Twenty-nine of these dams produce conventional hydroelectric
power, and one additional project is solely a pumped storage hydroelectric
project. The reservoir system provides 800 miles of commercially
navigable waterway, and also provides significant flood reduction benefits
both
within the Tennessee River system and downstream on the lower Ohio and
Mississippi Rivers. The reservoir system also provides a water supply
for residential and industrial customers, as well as cooling water for some
of
TVA’s coal-fired and nuclear power plants.
TVA
reservoirs and public lands provide
outdoor recreation opportunities for millions of visitors each
year. TVA has stewardship responsibility for approximately 293,000
acres of reservoir land, 11,000 miles of shoreline, and 650,000 acres of
reservoir water surface available for recreation and other
purposes. TVA furnishes over 100 recreation facilities such as
campgrounds, boat ramps, fishing piers, and picnic areas.
Weather
affects both the demand for and
the market prices of electricity. TVA’s power system generally peaks
in the summer, with a slightly lower peak in the winter. After
meeting a peak demand of over 32,000 megawatts for the first time in 2006,
TVA
met peak demands that exceeded 33,000 megawatts six times in August
2007. TVA met its highest winter peak demand of 30,320 megawatts on
January 31, 2007, and met its highest peak power demand ever, at 33,482
megawatts, late in the afternoon on August 16, 2007, when the average
temperature across the Tennessee Valley was 102 degrees
Fahrenheit. See Item 1A, Risk Factors, for a discussion of the
potential impact of weather on TVA.
TVA
uses weather degree days to measure
the impact of weather on TVA’s power operations. Weather degree days
measure the extent to which average temperatures in the five largest cities
in
TVA's service area vary from 65 degrees Fahrenheit. TVA
calculates weather degree days for Memphis, Nashville, Knoxville, and
Chattanooga, Tennessee, and Huntsville, Alabama, the five largest cities in
TVA’s service area.
During
2007, TVA had five more heating
degree days and 253 more cooling degree days than in 2006. The graph
below shows the number of heating and cooling degree days for 2007, 2006, and
2005 as compared to the normal number of heating and cooling degree
days. See Item 7, Management’s Discussion and Analysis of Financial
Condition and Results of Operations —
Executive Summary — Challenges During
2007 — Weather Conditions.
2007
was the driest year in the eastern
Tennessee Valley in 118 years of record-keeping with rainfall 66 percent of
normal for the year and runoff 54 percent of normal. Largely as a
result of this low rainfall and runoff, TVA’s hydroelectric production for 2007
was slightly more than nine billion kilowatt-hours, which was nine percent,
42
percent, and 35 percent lower than 2006, 2005, and 2004,
respectively.
The
hot weather and low rainfall were
also significant factors in causing TVA to reduce output at several generating
plants during the period of mid-June through mid-September. During
this period, temperatures on the Tennessee and Cumberland Rivers reached levels
at which discharging cooling water from some of TVA’s plants into the rivers
could have caused the permitted thermal limits for the rivers to be
exceeded. While every effort was made to lower electrical output
during low load periods (derates) to reduce financial and operational impacts,
some derates were required during higher load daytime hours to meet the
permitted temperature limits. These conditions caused TVA to rely
heavily on purchased power and more expensive generation sources such as
combustion turbines during 2007. See Item 7, Management’s Discussion
and Analysis of Financial Condition and Results of Operations —
Executive
Summary —Challenges During 2007 — Weather Conditions
.
TVA
sells electricity in a service area
that is largely free of competition from other electric power
providers. This service area is defined primarily by two provisions
of law: one called the “fence” and one called the
“anti-cherrypicking” provision. The fence limits the region in which
TVA or distributors of TVA power may provide power. The
anti-cherrypicking provision limits the ability of others to use the TVA
transmission system for the purpose of serving customers within TVA’s service
area. Bristol, Virginia, was exempted from the anti-cherrypicking
provision.
Recently
there have been efforts to
erode the protection of the anti-cherrypicking provision. FERC issued
an order that would have required TVA to interconnect its transmission system
with the transmission system of East Kentucky Power Cooperative, Inc. (“East
Kentucky”) in what TVA believed was a violation of the anti-cherrypicking
provision. See Item 3, Legal Proceedings. Additionally,
Senators Jim Bunning and Mitch McConnell introduced the Access to Competitive
Power Act of 2007 in the Senate that would, among other things, provide that
the
anti-cherrypicking provision would not apply with respect to any distributor
which provided a termination notice to TVA before December 31, 2006, regardless
of whether the notice was later withdrawn or rescinded. See Item 7,
Management’s Discussion and Analysis of Financial Condition and Results of
Operations —
Legislative and Regulatory Matters
. While the
FERC action involving East Kentucky now appears to be moot and the proposed
legislation has not made it to the Senate floor, the events illustrate how
the
protection to TVA’s service area provided by the anti-cherrypicking provision
could be called into question and perhaps eliminated at some time in the
future.
Congress
TVA
exists pursuant to legislation
enacted by Congress and carries on its operations in accordance with this
legislation. Congress has the authority to change this legislation
and thereby expand, reduce, or eliminate TVA’s activities, significantly change
TVA’s structure, require TVA to sell all or a portion of its assets, or reduce
the U.S. government's ownership interest in TVA. To allow TVA to
operate more flexibly than a traditional government agency, Congress exempted
TVA from some general federal laws that govern other agencies, such as laws
related to the hiring of employees, the procurement of supplies and services,
and the acquisition of land. Other federal laws enacted since the
creation of TVA have been made applicable to TVA including those related to
the
protection of the environment, cultural resources, and civil rights
laws.
Securities and Exchange Commission
Section
37 was added to the Securities
Exchange Act of 1934, as amended (the “Exchange Act”), as part of the
Consolidated Appropriations Act, 2005. Section 37 requires TVA to
file with the Securities and Exchange Commission such periodic, current, and
supplementary information, documents, and reports as would be required pursuant
to section 13 of the Exchange Act if TVA were an issuer of a security registered
pursuant to section 12 of the Exchange Act. TVA is also exempted by
section 37 of the Exchange Act from complying with section 10A(m)(3) of the
Exchange Act, which requires each member of a listed issuer’s audit committee to
be an independent member of the board of directors of the
issuer. Since TVA is an agency and instrumentality of the United
States, securities issued or guaranteed by TVA are “exempted securities” under
the Securities Act of 1933, as amended (the “Securities Act”), and may be
offered and sold without registration under the Securities Act. In
addition, securities issued or guaranteed by TVA are “exempted securities” and
“government securities” under the Exchange Act. TVA is also exempt
from sections 14(a)-(d) and 14(f)-(h) of the
Exchange
Act (which address proxy solicitations) insofar as those sections relate to
securities issued by TVA, and transactions in TVA securities are exempt from
rules governing tender offers under Regulation 14E of the Exchange
Act. In addition, since TVA securities are exempted securities under
the Securities Act, TVA is exempt from the Trust Indenture Act of 1939 insofar
as it relates to securities issued by TVA, and no independent trustee is
required for these securities.
Federal
Energy Regulatory Commission
TVA
is not a “public utility” as
defined in the Federal Power Act (“FPA”), a term which generally includes
investor-owned utilities. Therefore, TVA is not subject to the full
jurisdiction that FERC exercises over public utilities under the
FPA. TVA is, however, an “electric utility” as defined in the FPA
and, thus, is directly subject to certain aspects of FERC’s
jurisdiction.
•
|
Under
section 210 of the FPA, TVA can be ordered to interconnect its
transmission facilities with the electrical facilities of qualified
generators and other electric utilities that meet certain
requirements. It must be found that the requested
interconnection is in the public interest and would either encourage
conservation of energy or capital, optimize efficiency of facilities
or
resources, or improve reliability. The requirements of
section 212 concerning the terms and conditions of interconnection,
including reimbursement of costs, must also be
met.
|
•
|
Under
section 211 of the FPA, TVA can be ordered to transmit power at
wholesale provided that the order does not impair the reliability
of the
TVA or surrounding systems and likewise meets the applicable requirements
of section 212 concerning terms, conditions, and rates for
service. Under section 211A of the FPA, TVA is subject to FERC
review of the transmission rates and the terms and conditions of
service
that TVA provides others to ensure comparability of treatment of
such
service with TVA’s own use of its transmission system. With the
exception of wheeling power to Bristol, Virginia, the anti-cherrypicking
provision of the FPA precludes TVA from being ordered to wheel another
supplier’s power to a customer if the power would be consumed within TVA’s
defined service territory.
|
•
|
Sections
221 and 222 of the FPA, applicable to all market participants, including
TVA, prohibit (i) using manipulative or deceptive devices or
contrivances in connection with the purchase or sale of power or
transmission services subject to FERC’s jurisdiction and (ii) reporting
false information on the price of electricity sold at wholesale or
the
availability of transmission capacity to a federal agency with intent
to
fraudulently affect the data being compiled by the
agency.
|
•
|
Section
206(e) of the FPA provides FERC with authority to order refunds of
excessive prices on short-term sales (transactions lasting 31 days
or
less) by all market participants, including TVA, in market manipulation
and price gouging situations if such sales are under a FERC-approved
tariff.
|
•
|
Section
220 of the FPA provides FERC with authority to issue regulations
requiring
the reporting, on a timely basis, of information about the availability
and prices of wholesale power and transmission service by all market
participants, including TVA.
|
•
|
Under
sections 306 and 307 of the FPA, FERC may investigate electric
industry practices, including TVA’s operations previously mentioned that
are subject to FERC’s jurisdiction.
|
•
|
Under
sections 316 and 316A of the FPA, FERC has authority to impose
criminal penalties and civil penalties of up to $1 million a day for
each violation on entities subject to the provisions of Part II of
the FPA, which includes the above provisions applicable to
TVA.
|
Finally,
while not required to do so,
TVA has elected to implement various FERC orders and regulations pertaining
to
public utilities on a voluntary basis to the extent that these are consistent
with TVA’s obligations under the TVA Act.
For
a discussion of legislation that
could change FERC’s ability to regulate TVA, see Item 7, Management’s Discussion
and Analysis of Financial Condition and Results of Operations —
Legislative
and Regulatory Matters
.
Nuclear
Regulatory Commission
TVA,
like other utilities, operates its
nuclear facilities in a highly regulated environment and is subject to the
oversight of the NRC, an independent agency which sets the rules that users
of
radioactive materials must follow. The NRC has broad authority to
impose requirements relating to the licensing, operation, and decommissioning
of
nuclear generating facilities. In addition, if TVA fails to comply with
requirements promulgated by the NRC, the NRC has the authority to impose fines,
shut down units, or modify, suspend, or revoke TVA’s operating
licenses.
Environmental
Protection
Agency
TVA
is subject to regulation by the
Environmental Protection Agency (“EPA”) in a variety of areas, including air
quality control, water quality control, and management and disposal of hazardous
wastes. See Item 1, Business —
Environmental
Matters.
States
The
Supremacy Clause of the U.S.
Constitution prohibits states, without congressional consent, from regulating
the manner in which the federal government conducts its
activities. As a federal agency, TVA is exempt from regulation,
control, and taxation by states except in certain areas such as air and water
quality where Congress has given the states limited powers to regulate federal
activities.
Other
Federal Entities
TVA’s
activities and records are also
subject to review by various entities including TVA’s Office of Inspector
General and the following agencies: the Government Accountability
Office, the Congressional Budget Office, and the Office of Management and
Budget.
TVA
is not subject to federal income
taxes, and neither TVA nor its property, franchises, or income are subject
to
taxation by states or their subdivisions. However, the TVA Act
requires TVA to make payments in lieu of taxes to states and counties in which
TVA conducts power operations and in which TVA has acquired properties
previously subject to state and local taxation. The total amount of
these payments is five percent of gross revenues from the sale of power during
the preceding year excluding sales or deliveries to other federal agencies
and
off-system sales with other utilities, with a provision for minimum payments
under certain circumstances. Distribution of in lieu of tax payments
within a state is determined by individual state legislation.
TVA’s
power generation activities, like
those across the utility industry and in other industrial sectors, are subject
to federal, state, and local environmental statutes and
regulations. Major areas of regulation affecting TVA’s activities
include air quality control, water quality control, and management and disposal
of solid and hazardous wastes.
TVA
has incurred, and expects to
continue to incur, substantial capital and operating and maintenance costs
to
comply with evolving environmental requirements primarily associated with the
operation of TVA’s 59 coal-fired generating units. While these
evolving requirements will impact the operation of existing and new coal-fired
and other fossil-fuel generating units, it is virtually certain that
environmental requirements placed on the operation of these generating units
will continue to become more restrictive. Litigation over emissions
from coal-fired generating units is also occurring, including litigation against
TVA. See Item 3, Legal Proceedings
.
Several
existing regulatory programs that apply to fossil-fuel units are becoming more
stringent, and additional regulatory programs affecting fossil-fuel units were
promulgated in 2005. These new regulatory programs include the Clean
Air Interstate Rule (“CAIR”) and the Clean Air Mercury Rule
(“CAMR”). CAIR requires significant additional utility reductions of
emissions of sulfur dioxide (“SO
2
”) and nitrogen
oxides (“NO
x
”)
in the eastern half of the United States (including all of TVA’s operating
area), and CAMR establishes caps for overall mercury emissions in two phases
with the first phase becoming effective in 2010 and the second in
2018. TVA had previously estimated its total capital cost for
reducing emissions from its power plants from 1977 through 2010 would reach
$5.8
billion, $4.8 billion of which had already been spent as of September 30,
2007. TVA estimates that compliance with CAIR and CAMR could lead to
additional costs of $3.0 billion to $3.6 billion in the decade beginning in
2011. As discussed in more detail below, there could be additional
material costs if reductions of carbon dioxide (“CO
2
”) are mandated
or
if future legislative, regulatory, or judicial actions lead to more stringent
emission reduction requirements. These costs cannot reasonably be
predicted at this time.
In
addition, an existing federal water
regulation covering cooling water intake structures and temperatures may also
become more stringent. In January 2007, the United States Court of
Appeals for the Second Circuit Court (“Second Circuit”) remanded EPA’s rule on
this subject. In response, EPA has suspended the rule, and several
parties are seeking United States Supreme Court review of the Second Circuit
decision. If the Second Circuit’s decision becomes law after all
appeal processes and the issuance of a new rule, compliance is expected to
be
more costly for the power industry. TVA is unable at this time to estimate
these
costs.
Clean
Air
Developments
Air
quality in the United States has
significantly improved since the enactment of the modern Clean Air Act (“CAA”)
in 1970. These air quality improvements are expected to continue as
the CAA continues to be implemented and as programs evolve as a result of
legislative and regulatory changes. Three substances emitted from
coal-fired units have been the focus of emission reduction regulatory programs:
SO
2
, NO
x
,
and
particulates. Expenditures related to clean air projects during 2007
and 2006 were approximately $239 million and $182 million,
respectively. These figures include expenditures in 2007 of $7
million to continue to reduce NO
x
emissions
through
the installation of selective catalytic reduction (“SCR”) and selective
non-catalytic reduction (“SNCR”) systems and $207 million for the installation
of flue gas desulfurization systems (“scrubbers”) to continue to reduce SO
2
emissions,
each of
which is explained in more detail below. The aforementioned estimate
of $5.8 billion does not include additional capital costs of $3.0 billion to
$3.6 billion that TVA expects to incur over the decade beginning in 2011 to
comply with CAIR and CAMR. Increasingly stringent regulation of some
or all of these substances, as well as mercury and possibly CO
2
, will continue
to
result in significant capital and operating costs for TVA’s coal-fired
generating units.
Sulfur
Dioxide.
Coal-fired utilities have historically emitted large
amounts of SO
2
compared to today’s emissions. Utility SO
2
emissions
are
currently regulated under the Federal Acid Rain Program and state programs
designed to meet the National Ambient Air Quality Standards (“NAAQS”) for
SO
2
and fine
particulate matter. Looking forward, additional regulation of SO
2
emissions
will
result from implementation of the Regional Haze Program and CAIR. In
May 2005, EPA finalized CAIR to reduce the interstate transport of fine
particulate matter and ozone by requiring additional large reductions in utility
emissions of NO
X
and SO
2
from 28 eastern
states. All seven states in TVA’s service area are submitting plans
to EPA to implement CAIR through state rules and have only proposed a few minor
modifications to the federal model rule which establishes an emission allowance
driven program, capping regional emissions of SO
2
and NO
x
among the targeted
states. SO
2
caps are
reduced in
two phases, 2010 and 2015.
Since
1977, TVA has reduced its SO
2
emissions
by
approximately 80 percent by switching to lower-sulfur coals, re-powering a
unit
at its Shawnee Fossil Plant with Atmospheric Fluidized Bed Combustion (“AFBC”)
technology, and installing scrubbers on seven of its larger
units. TVA began construction in 2005 on its eighth scrubber at its
Bull Run Fossil Plant and in 2006 began construction on two more scrubbers
at
its Kingston Fossil Plant as part of its previously announced plans to achieve
a
total SO
2
emission reduction of 80 to 85 percent compared to the 1977
level. Additionally, TVA has switched, or plans to switch, to
lower-sulfur coal at several additional units in the next few
years. It is likely that additional emission reduction measures will
have to be undertaken after these planned actions are completed to achieve
compliance with CAIR and any future tightening of applicable
requirements.
Nitrogen
Oxides.
Utility
NO
x
emissions
continue to be regulated under state programs to achieve and maintain EPA’s
NAAQS for ozone, the Federal Acid Rain Program, the Regional Haze Program,
and
CAIR. Since 1995, TVA has reduced its NO
x
emissions
during
the summer (when ozone levels increase) by 81 percent by installing various
controls including low-NO
x
burners
and/or
combustion controls on 58 of its 59 coal-fired units and installing SCRs on
21
of the largest units. (The AFBC unit at Shawnee Fossil Plant is inherently
low
NO
x
emitting.)
In
2005, TVA installed SNCR systems on
two units to demonstrate long-term technology capability, and continued to
operate the SNCR at Johnsonville Unit 1 through the 2007 ozone
season. SNCRs generally have lower NO
x
removal
capabilities than SCRs. Early in 2006, TVA began testing a High
Energy Reagent Technology (“HERT”) on three units for potential future
application. HERT is similar to SNCR but has higher removal
capabilities than SNCRs. The initial HERT testing program was
successful, and in 2007, TVA installed this technology on two coal-fired units
(Johnsonville Unit 4 and John Sevier Unit 1) to demonstrate the HERT technology
on a potentially permanent basis. Similar equipment is planned for
installation on the other three John Sevier units and Johnsonville Units 2
and 3
by 2009.
TVA’s
NO
x
emission
reduction
program is expected to continue to depend primarily on SCRs, but will also
incorporate some mix of SNCRs and/or HERTs as TVA gains more experience with
these technologies. These plans may change depending on the timing
and severity of future regulatory developments affecting power plant
emissions.
On
June 21, 2007, EPA proposed
lowering the eight-hour ozone NAAQS. This proposal began a process that is
expected to lead to a final decision in March 2008 on revising the ozone
standard. Meeting the more stringent EPA standards for ozone contained in the
proposal will challenge states and communities in the Tennessee Valley and
across the country.
The
current primary standard, set in
1997, is 0.08 parts per million (“ppm”). EPA is proposing to lower the primary
standard to between 0.075 ppm and 0.070 ppm, and is also proposing to add a
new
secondary ozone standard to address impacts on vegetation. If EPA adopts the
proposed standards, many urban areas and surrounding counties in the Tennessee
Valley and throughout the eastern United States are likely to be designated
as
“non-attainment” areas (defined as geographic areas where air quality does not
meet standards). Non-attainment designations can have adverse
economic implications for areas that are so designated. Existing emission
sources in non-attainment areas can be required to install additional controls,
and new sources planning to locate in such areas are required to meet more
stringent emission control requirements and obtain offsets for their emissions
from other sources in the non-attainment area. In addition, transportation
projects, such as roadway expansions or repairs, must demonstrate conformity
with state plans to achieve attainment status or risk the loss of federal
highway funds. An increase in the number of counties in the Tennessee Valley
designated as non-attainment areas is also likely to focus additional regulatory
attention on all NO
x
emission
sources
including TVA sources.
Particulates/Opacity.
Coarse
particulates (defined as particles of 10 micrometers or larger), which include
fly ash, have long been regulated by states to meet EPA’s NAAQS for particulate
matter. All of TVA’s coal-fired units have been equipped with mechanical
collectors, electrostatic precipitators, scrubbers, or baghouses, which have
reduced particulate emissions from the TVA system by more than 99 percent
compared to uncontrolled units. In 1997, EPA issued separate NAAQS
for even smaller particles with a size of up to 2.5 micrometers (“fine
particles”). In December 2004 and April 2005, EPA issued final
determinations regarding the areas of the country which are not in attainment
with the 1997 fine particles standard. Those non-attainment areas include
counties and parts of counties in the Knoxville and Chattanooga, Tennessee,
metropolitan areas. In September 2006, EPA revised the 1997
standards. The 2006 revisions tighten the 24-hour fine particle
standard and retain the 1997 annual fine particle standard. EPA also
decided to retain the existing 24-hour standard for coarse particles, but
revoked the related annual standard. The last three years of
monitoring data (2004 to 2006) for the Nashville, Chattanooga, Memphis, and
Clarksville/Hopkinsville areas show that these areas will be close to meeting
the more stringent 2006 24-hour and annual fine particle
standards. Attainment designations are scheduled to be made by EPA in
December 2008. CAIR is intended to help states attain the fine
particle standards, and actions taken to reduce emissions under CAIR, including
those planned by TVA, are expected to continue to reduce fine particle
levels.
Issues
regarding utility compliance
with state opacity requirements are also increasing. Opacity measures
the denseness (or color) of power plant plumes and has traditionally been used
by states as a means of monitoring good maintenance and operation of particulate
control equipment. Under some conditions, retrofitting a unit with
additional equipment to better control SO
2
and NO
x
emissions can
adversely affect opacity performance, and TVA and other utilities are now
addressing this issue. There are also disputes and lawsuits with
special interest groups over the role of continuous opacity monitors in
determining compliance with opacity limitations, and TVA has received an adverse
decision in one such lawsuit. See Item 3, Legal
Proceedings.
Mercury.
In
March
2005, the EPA issued CAMR, which establishes caps for overall mercury emissions
in two phases, with the first phase becoming effective in 2010 and the second
in
2018. It allows the states to regulate mercury emissions through a
market-based cap-and-trade program. All of the states in which TVA
operates potentially affected sources have adopted CAMR without significant
change. In response to a request for reconsideration, the EPA
confirmed its approach in May 2006. In June 2006, 16 states and
several environmental groups filed lawsuits challenging CAMR. This
lawsuit is currently pending. TVA cannot predict the outcome of the
pending challenge of CAMR, or what effects any decision may have that would
require the EPA to regulate mercury as a hazardous air pollutant. If
the EPA’s decisions are upheld and CAMR is implemented, TVA expects to achieve
the required mercury reductions for at least Phase I of CAMR from co-benefits
of
the installation of additional emission control technology in connection with
the implementation of CAIR.
CAMR
does, however, require the
installation of new mercury emission monitoring equipment prior to January
1,
2009. TVA is planning to comply with this requirement by procuring,
installing, and certifying approximately 23 monitoring systems by the end of
calendar year 2008. The costs associated with the monitoring systems
have been incorporated into TVA's capital budget.
Carbon
Dioxide.
Legislation has been introduced in Congress to require reductions of CO
2
and, if
enacted,
could result in significant additional costs for TVA and other utilities with
coal-fired generation. The current Administration has implemented a
voluntary initiative with the goal of reducing the greenhouse gas intensity
of
the U.S. economy by 18 percent and has asked the electric utility sector and
other industry sectors to support this initiative. TVA is supporting
this effort in cooperation with electric utility industry trade associations
and
the DOE. TVA has taken and is continuing to take significant
voluntary steps to reduce the carbon intensity of its electric generation,
including the recovery of Browns Ferry Unit 1, planned power uprates of Browns
Ferry Units 2 and 3, the planned completion of Watts Bar Unit 2, and the
completion of the hydroelectric modernization program. TVA has also
applied to the NRC for a Combined License for two advanced nuclear reactors
at
the Bellefonte Nuclear Plant near Hollywood, Alabama, although no decision
has
been made to build the reactors. Looking ahead, TVA intends to make
decisions that give strong consideration to fuel mix and
generating
assets that are low or zero carbon emitting resources. In addition to these
activities, TVA is a member of the Southeast Regional Carbon Sequestration
Partnership and is working with the Electric Power Research Institute and other
electric utilities on projects investigating technologies for CO
2
capture
and
geologic storage, as well as carbon sequestration via
reforestation. The previous Administration asked utilities to
voluntarily participate in an effort to reduce, sequester, or avoid greenhouse
gases. Under that program, TVA reduced or avoided more than 305
million tons of CO
2
from 1994
through
2005, as reported under Section 1605b of the Energy Policy Act. TVA
is incorporating the possibility of mandatory carbon reductions and a renewable
portfolio standard into its long range planning, and will continue to monitor
legislative and regulatory developments related to CO
2
and a renewable
portfolio standard to assess any potential financial impacts as information
becomes available.
In
addition to legislative activity,
climate change issues are the subject of a number of lawsuits, including
lawsuits against TVA. See Item 3, Legal Proceedings. On
November 29, 2006, the U.S. Supreme Court heard the case of
Massachusetts v.
EPA
, concerning whether EPA has the authority and duty to regulate CO
2
emissions
under the
CAA. The District of Columbia Circuit Court of Appeals earlier
affirmed EPA’s decision not to regulate CO
2
. On
April 2, 2007, the Supreme Court found that greenhouse gases, including CO
2
, are pollutants
under the CAA and thus EPA does have the authority to regulate these
gases. The Supreme Court also concluded that EPA's refusal to regulate
these pollutants was based on impermissible reasons, and remanded the case
to
EPA to "ground its reasons for action or inaction in the
statute." While this case focused on CO
2
emissions
from
motor vehicles, it sets a precedent for regulation in other industrial sectors,
such as the electric utility industry.
States
are also becoming more active in
the regulation of emissions that are believed to be contributing to global
climate change. Several northeastern states have formed the Regional
Greenhouse Gas Initiative which is in the process of being implemented, and
California recently passed a bill capping greenhouse gas emissions in the
state. Other states are considering a variety of actions. North
Carolina is studying initiatives aimed at climate change under the provisions
of
the state’s Clean Smokestacks Act of 2002. This act required the
State Division of Air Quality to study potential control of CO
2
emissions
from
coal-fired utility plants and other stationary sources. This effort
has also prompted actions to develop a climate action plan for North
Carolina.
Clean
Water
Developments
One
of the results of the major
reductions in atmospheric emissions resulting from the clean air expenditures
discussed above is that wastewaters at TVA coal-fired facilities and across
the
utility industry may be changing because of waste streams from air quality
control technologies. Varying amounts of ammonia or similar compounds used
as a
necessary component of SCR and SNCR operations may end up in facility wastewater
ponds that may discharge through outfalls regulated under the Clean Water Act
(“CWA”). Operation of scrubbers for SO
2
control
also
results in additional amounts of pollutants introduced into facility wastewater
treatment ponds. EPA is currently collecting information to determine if the
Steam Electric Point Source Effluent Guidelines (“Effluent Guidelines”) under
the CWA need to be revised. If the Effluent Guidelines are revised, potentially
more restrictive discharge limitations for existing parameters or the addition
of new parameters could result in additional wastewater treatment expense to
meet requirements of the CWA. These costs cannot be accurately predicted at
this
time, but TVA is involved in and closely monitoring EPA’s data collection
activities and the progress of the Effluent Guidelines review process. On the
state level, new numeric nutrient criteria development and implementation (an
EPA requirement) may require additional treatment costs to reduce nitrogen
concentrations being added to the waste treatment ponds as a result of the
operation of air pollution control equipment. TVA is closely monitoring the
development and implementation of numeric nutrient criteria by the states in
TVA’s service area.
In
the
second phase of a three-part rulemaking to minimize the adverse impacts from
cooling water intake structures on fish and shellfish, as required under Section
316(b) of the CWA, the EPA promulgated a final rule for existing power producing
facilities (the “Phase II Rule”) that became effective on September 7,
2004. The Phase II Rule required existing facilities to select among several
different compliance options for reducing the number of organisms pinned against
and/or drawn into the cooling systems. These options included development of
a
site-specific compliance option based on application of cost-cost or
cost-benefit tests. The site specific tests were designed to ensure that a
facility’s costs are not significantly greater than cost projections in the rule
or the benefits derived from taking mitigation actions. Actions taken to
compensate for any impacts by restoring habitat, or pursuing other options
such
as building hatcheries for fish/shellfish production, would have counted towards
compliance. Some northeastern states and environmental groups
challenged the new regulation, especially the compliance flexibility it offered,
in federal court.
On
January 25, 2007, the Second Circuit
issued its decision in the proceeding challenging the EPA's Phase II Rule.
The
Second Circuit held that costs cannot be compared to benefits in picking the
best technology available (“BTA”) to minimize the adverse environmental
impacts of intake structures. Instead, the court held that the EPA is
allowed to consider costs in two ways: (1) to determine what technology can
reasonably be borne by industry; and (2) to engage in cost-effectiveness
analysis in determining BTA. Finding the rulemaking record to be unclear on
whether the EPA had relied
on
a
cost-benefit analysis or a cost-effectiveness analysis, the Second Circuit
remanded the EPA's BTA determination, giving the EPA the option to provide
a
reasonable explanation of its determination or make a new determination based
on
the permissible cost considerations set out in the Second Circuit
opinion. The Second Circuit also remanded provisions of the EPA rule that
allowed the use of a site-specific cost-benefit test and restoration measures
(such as building hatcheries) to demonstrate compliance, holding that these
rule
provisions were based on an impermissible construction of the statute. Several
other provisions of the Phase II Rule such as the one that sets the performance
standards as a range rather than one national standard were also remanded.
On
July 9, 2007, EPA suspended all but
one provision of the Phase II Rule until the agency has resolved the issues
raised by the Second Circuit's remand. The provision that was
retained requires permitting authorities to apply, in the interim, Best
Professional Judgment (“BPJ”) controls for existing facilities. BPJ
controls are those that reflect the best technology available for minimizing
the
adverse environmental impacts of intake structures. The use of BPJ
controls reflects a reversion to the regulatory process that was used by
permitting authorities to regulate the impact of intake structures prior to
the
promulgation of the Phase II Rule.
All
of the intakes at TVA's existing
coal and nuclear generating facilities were subject to the Phase II
Rule. TVA had been in the process of determining what was needed to
comply with the Phase II Rule, and had believed that some expenditures might
have been required. These earlier assessments are now being
re-evaluated in light of the Second Circuit's decision, and EPA's subsequent
decision to suspend the Phase II Rule and revert to BPJ
controls. Given the uncertainty over the ultimate outcome of the
appellate process and what the changes in the final rule as ultimately issued
by
EPA will be, TVA cannot assess the potential consequences at this
time.
As
a part
of the 2006 triennial review of State Water Quality Standards in Tennessee,
the
Tennessee Department of Environment and Conservation (“TDEC”) lowered its
threshold for issuing a Precautionary Fish Consumption Advisory (“Precautionary
Advisory”) due to mercury to 0.3 ppm because of new research and the EPA’s new
water quality criterion for methylmercury. The previous thresholds were 0.5
ppm
for a Precautionary Advisory and 1.0 ppm for a “Do Not Consume Advisory.” In
Tennessee a Precautionary Advisory recommends that sensitive populations such
as
children and women of child-bearing age should not consume the fish species
named, and that all other persons should limit consumption of the named species
to one meal per month. A “Do Not Consume Advisory” recommends that certain fish
species should not be consumed by anyone in any amount. As a result of lowering
the threshold, Precautionary Advisories were issued for several additional
stream and reservoir segments within the State of Tennessee, including seven
streams and reservoir segments in the Tennessee River Watershed. TDEC’s
announcement of additional Precautionary Advisories for several Tennessee water
bodies does not mean that mercury levels in fish are increasing. TVA has been
monitoring mercury levels in fish and sediments in TVA reservoirs for the last
35 years, and TVA’s data was provided to TDEC as a part of its review
process. TVA’s data show significant reductions in mercury concentrations in
fish from the reservoirs with known industrial discharges that have now ceased
operation. Other than those areas historically impacted by industrial
discharges, mercury concentrations in fish have tended to fluctuate through
time
with no discernible trend in fish from most reservoirs. Despite increased
burning of coal for electricity generation, current and historic data records
indicate that mercury concentrations in reservoir sediments have remained stable
or declined.
As
is the case across the utility
industry and in other industrial sectors, TVA is also facing more stringent
requirements related to protection of wetlands, reductions in storm water
impacts from construction activities, water quality degradation, new water
quality criteria, and laboratory analytical methods. TVA is also
following litigation related to the use of herbicides, water transfers, and
releases from dams. TVA is not facing any substantive requirements
related to non-compliance with existing CWA regulations.
Hazardous Substances
Liability
for releases and cleanup of
hazardous substances is regulated under the federal Comprehensive Environmental
Response, Compensation, and Liability Act, among other statutes, and similar
state statutes. In a manner similar to many other industries and
power systems, TVA has generated or used hazardous substances over the
years. TVA operations at some TVA facilities have resulted in
releases of hazardous substances and/or oil which require cleanup and/or
remediation. TVA also is aware of alleged hazardous-substance
releases at 10 non-TVA areas for which it may have some
liability. TVA has reached agreements with EPA to settle its
liability at two of the non-TVA areas for a total of less than
$23,000. There have been no recent assertions of TVA liability for
six of the non-TVA areas, and (depending on the site) there is little or no
known evidence that TVA contributed any significant quantity of hazardous
substances to these six sites. There is evidence that TVA sent materials to
the
remaining two non-TVA areas: the David Witherspoon site in Knoxville, Tennessee,
and the Ward Transformer site in Raleigh, North Carolina. As
discussed below, TVA is not able to estimate its liability related to these
sites at this time.
The
Witherspoon site is contaminated
with radionuclides, polychlorinated biphenyls (“PCBs”), and
metals. DOE has admitted to being the main contributor of materials
to the Witherspoon site and is currently performing clean-up
activities. DOE claims that TVA sent equipment to be recycled at this
facility, and there is some supporting evidence for the
claim. However, TVA believes it sent only a relatively small amount
of equipment and that none of it was radioactive. DOE has asked TVA
to “cooperate” in completing the cleanup, but it has not provided to TVA any
evidence of TVA’s percentage share of the contamination.
At
the Ward Transformer site, EPA and a
working group of potentially responsible parties ("PRPs") have provided
documentation showing that TVA sent electrical equipment containing PCBs to
this
site in 1974. The working group is cleaning up on-site contamination
in accordance with an agreement with EPA and plans to sue non-participating
PRPs
for contribution. The estimated cost of the cleanup is $20
million. In addition, EPA likely has incurred several million dollars
in response costs, and the working group has reimbursed EPA approximately
$725,000 of those costs. EPA has also proposed a cleanup plan for
off-site contamination. The present worth cost estimate for
performing the proposed plan is about $5 million. In addition, there
may be natural resource damages liability related to this site, but TVA is
not
aware of any estimated amount for any such damages.
As
of September 30, 2007, TVA’s
estimated liability for environmental cleanup for those sites for which
sufficient information is available to develop a cost estimate (primarily the
TVA sites) is approximately $20 million on a non-discounted basis and is
included in Other liabilities on the Balance Sheet.
Coal-Combustion
Wastes
In
accordance with a regulatory
determination by EPA in May 2000, coal-combustion and certain related wastes
disposed of in landfills and surface impoundments continue to be regulated
as
non-hazardous. In conjunction with this determination, EPA committed
to developing non-hazardous management standards for these
wastes. These standards are likely to include increased groundwater
monitoring, more stringent siting requirements, and closure of existing
waste-management facilities not meeting minimum standards. On August
29, 2007, EPA issued a Notice of Data Availability in which it requested public
comment on whether the additional information mentioned in the notice should
affect the EPA’s decisions as it continues to follow up on its commitment to
develop management standards for coal-combustion wastes. TVA is
currently reviewing this information to evaluate its potential impact on TVA
operations.
On
September 30, 2007, TVA had 12,013
employees, of whom 5,167 were trades and labor employees. Under the
TVA Act, TVA is required to pay trades and labor workers hired by TVA or its
contractors the prevailing rate of wages. This rate is the rate of
wages for work of a similar nature prevailing in the vicinity where the work
is
being performed. Neither the federal labor relations laws covering
most private sector employers nor those covering most federal agencies apply
to
TVA. However, the TVA Board has a long-standing policy of
acknowledging and dealing with recognized representatives of its employees,
and
that policy is reflected in long-term agreements to recognize the unions (or
their successors) that represent TVA employees. Federal law prohibits
TVA employees from engaging in strikes against TVA.
The
risk factors described below, as
well as the other information included in this Annual Report, should be
carefully considered. Risks and uncertainties described in these risk
factors could cause future results to differ materially from historical results
as well as from the results predicted in forward-looking
statements. Although the risk factors described below are the ones
that TVA management considers significant, additional risk factors that are
not
presently known to TVA management or that TVA management presently considers
insignificant may also impair TVA’s business operations. Although TVA
has the authority to set its own rates and thus mitigate some risks by
increasing rates, it is possible that partially or completely eliminating one
or
more of these risks through rate increases might adversely affect TVA
commercially or politically. Accordingly, the occurrence of any of
the following could have a material adverse effect on TVA’s cash flows, results
of operations, and financial condition.
For
ease of reference, the risk factors
are presented in four categories: strategic risks, operational risks, financial
risks, and risks related to TVA securities.
New
laws, regulations, and administrative orders may negatively affect TVA’s cash
flows, results of operations, and financial condition, as well as the way TVA
conducts its business.
Although
it is difficult to predict exactly how any new laws, regulations, and
administrative orders would impact TVA, some of the possible effects are
described below.
•
|
TVA
could lose its protected service
territory.
|
TVA’s
service area is primarily
defined by two provisions of law.
–
|
The
TVA Act provides that, subject to certain minor exceptions, neither
TVA
nor its distributor customers may be a source of power supply outside
of
TVA’s defined service area. This provision is often called the
“fence” since it limits TVA’s sales activities to a specified service
area.
|
–
|
The
Federal Power Act prevents FERC from ordering TVA to provide access
to
others to its transmission lines for the purpose of delivering power
to
customers within TVA’s defined service area, except to those customers
residing in Bristol, Virginia. This provision is often called
the “anti-cherrypicking provision” since it prevents competitors from
“cherrypicking” TVA’s customers.
|
If
Congress were to eliminate or reduce the coverage of the anti-cherrypicking
provision, TVA could more easily lose customers, and the loss of these customers
could adversely affect TVA’s cash flows, results of operations, and financial
condition. See Item 7, Management’s Discussion and Analysis of
Financial Condition and Results of Operations —
Legislative and Regulatory
Matters — Proposed Legislation.
•
|
The
TVA Board could lose its sole authority to set rates for
electricity.
|
Under
the
TVA Act, the TVA Board has the sole authority to set the rates that TVA charges
for electricity, and these rates are not subject to review. The loss
of this authority could have material adverse effects on TVA including, but
not
limited to, the following:
–
|
TVA
might be unable to set rates at a level sufficient to generate adequate
revenues to service its financial obligations, properly operate and
maintain its power assets, and provide for reinvestment in its power
program; and
|
–
|
TVA
might become subject to additional regulatory oversight that could
impede
TVA’s ability to manage its
business.
|
•
|
TVA
could become subject to increased environmental
regulation.
|
There
is
a risk that new environmental laws and regulations could become applicable
to
TVA or its facilities and that existing environmental regulations could be
revised or reinterpreted in a way that adversely affects TVA. For
example, proposals in Congress that would regulate CO
2
and other
greenhouse gases could require TVA and other electric utilities to incur
significantly increased costs. Any such developments could require
TVA to make significant capital expenditures, increase TVA’s operating and
maintenance costs, or even lead to TVA’s closing certain
facilities. See Item 1, Business —
Environmental
Matters
.
•
|
The
NRC could impose significant restrictions or requirements on
TVA.
|
The
NRC
has broad authority to impose requirements relating to the licensing, operation,
and decommissioning of nuclear generation facilities. If the NRC
modifies existing requirements or imposes new requirements, TVA could be
required to make substantial capital expenditures at its nuclear plants or
make
substantial contributions to its nuclear decommissioning trust. In
addition, if TVA fails to comply with requirements promulgated by the NRC,
the
NRC has the authority to impose fines, shut down units, or modify, suspend,
or
revoke TVA’s operating licenses. See Item 1, Business
—
Nuclear.
•
|
TVA
could lose responsibility for managing the Tennessee River
system.
|
TVA’s
management of the Tennessee River system is important to effective operation
of
the power system. TVA’s ability to integrate management of the
Tennessee River system with power system operations increases power system
reliability and reduces costs. Restrictions on how TVA manages the
Tennessee River system could negatively affect TVA’s operations.
•
|
Congress
could take actions that lead to a downgrade of TVA’s credit
rating.
|
TVA’s
rated securities are currently rated “Aaa” by Moody’s Investors Service and
“AAA” by Standard and Poor’s and Fitch Ratings, which are the highest ratings
assigned by these rating agencies. TVA’s credit ratings are not based
solely on its underlying business or financial condition, which by themselves
may not be commensurate with a triple-A rating. TVA’s current ratings
are based to a large extent on the body of legislation that defines TVA’s
business structure. Key characteristics of TVA’s business defined by
legislation include (1) the TVA Board’s ratemaking authority, (2) the current
competitive environment, which is defined by the fence and the
anti-cherrypicking provision, and (3) TVA’s status as a corporate agency and
instrumentality of the United States. Accordingly, if Congress takes
any action that effectively alters any of these characteristics, TVA’s credit
ratings could be downgraded.
•
|
TVA’s
debt ceiling could become more
restrictive.
|
The
TVA
Act provides that TVA can issue bonds, notes, and other evidences of
indebtedness (“Bonds”) in an amount not to exceed $30 billion outstanding at any
time. If Congress either lowers the debt ceiling or broadens the
types of financial instruments that are covered by the debt ceiling, TVA might
not be able to raise enough capital to, among other things, service its
financial obligations, properly operate and maintain its power assets, and
provide for reinvestment in its power program. See Item 7,
Management’s Discussion and Analysis of Financial Condition and Results of
Operations —
Legislative and Regulatory Matters — President’s
Budget.
TVA
may lose some of its customers.
As
of
September 30, 2007, three distributor customers had notices in effect
terminating their power contracts with TVA. Although sales to these
three distributor customers generated only 0.6 percent of TVA’s total operating
revenues in 2007, the loss of additional customers could have a material adverse
effect on TVA’s cash flows, results of operations, and financial
condition. See Item 1, Business —
Customers
—
Termination
Notices
and
Other Customers.
TVA’s
generation and transmission assets may not operate as
planned.
Many
of
TVA’s generation and transmission assets have been operating since the 1950s or
earlier and have been in near constant service since they were
completed. If these assets fail to operate as planned, TVA, among
other things:
•
|
Might
have to invest a significant amount of resources to repair or replace
the
assets;
|
•
|
Might
be unable to operate the assets for a significant period of
time;
|
•
|
Might
have to purchase replacement power on the open
market;
|
•
|
Might
not be able to meet its contractual obligations to deliver power;
and
|
•
|
Might
have to remediate collateral damage caused by a failure of the
assets.
|
In
addition, the failure of TVA’s assets to perform as planned could cause health,
safety, and environmental problems and even result in such events as the failure
of a dam or a nuclear accident. Any of these potential outcomes could
negatively affect TVA’s cash flows, results of operations, and financial
condition. See Item 7, Management’s Discussion and Analysis of
Financial Condition and Results of Operations —
Executive Summary —
Challenges During 2007.
TVA’s
fuel supply might be disrupted.
TVA
purchases coal, uranium, fuel oil, and natural gas from a number of
suppliers. Disruption in the acquisition or delivery of fuel may
result from a variety of factors, including, but not limited to, weather,
production or transportation difficulties, labor challenges, or environmental
regulations affecting TVA’s fuel suppliers. These disruptions could
adversely affect TVA’s ability to operate its facilities and could require TVA
to acquire power at higher prices on the spot market, purchase more expensive
alternative fuels, or operate higher cost plants, thereby adversely affecting
TVA’s cash flows, results of operations, and financial condition.
Compliance
with existing environmental laws and regulations may affect TVA’s operations in
unexpected ways.
TVA
is
subject to risks from existing federal, state, and local environmental laws
and
regulations including, but not limited to, the following:
•
|
Compliance
with existing environmental laws and regulations may cost TVA more
than it
anticipates.
|
•
|
At
some of TVA’s older facilities, it may be uneconomical for TVA to install
the necessary equipment to comply with future environmental laws,
which
may cause TVA to shut down those
facilities.
|
•
|
TVA
may be responsible for on-site liabilities associated with the
environmental condition of facilities that it has acquired or developed,
regardless of when the liabilities arose and whether they are known
or
unknown.
|
•
|
TVA
may be unable to obtain or maintain all required environmental regulatory
approvals. If there is a delay in obtaining any required
environmental regulatory approvals or if TVA fails to obtain, maintain,
or
comply with any such approval, TVA may be unable to operate its facilities
or may have to pay fines or
penalties.
|
See
Item
1, Business
— Environmental Matters
.
TVA
is the sole power provider for customers within its service area, and if demand
for power in TVA’s service area increases, TVA is contractually obligated to
take steps to meet this increased demand.
If
demand
for power in TVA’s service area increases, TVA may need to meet this increased
demand by purchasing power from other sources, building new generation and
transmission facilities, or purchasing existing generation and transmission
facilities. Purchasing power from external sources, as well as
acquiring or building new generation and transmission facilities, could
negatively affect TVA’s cash flows, results of operations, and financial
condition. See Item 7, Management’s Discussion and Analysis of
Financial Condition and Results of Operations —
Executive Summary —
Challenges During 2007 — Timing of Cash Flows.
Purchased
power prices may be highly volatile, and providers of purchased power may fail
to perform under their contracts with TVA.
TVA
acquires a portion of its electricity needs through purchased power
arrangements. The price for purchased power has been volatile in
recent years, and the price that TVA pays for purchased power may increase
significantly in the future. In addition, if one of TVA’s purchased
power suppliers fails to perform under the terms of its contract with TVA,
TVA
might have to purchase replacement power on the spot market, perhaps at a
significantly higher price than TVA was entitled to pay under the
contract. In some circumstances, TVA may not be able to recover
this difference from the supplier. Moreover, if TVA is unable to
acquire enough purchased power or enough replacement power on the spot market
and does not have enough reserve generation capacity available to offset the
loss of power from the purchased power supplier, TVA might not be able to supply
enough power to meet the demand resulting in power curtailments or even
blackouts. See Item 7, Management’s Discussion and Analysis of
Financial Condition and Results of Operations
— Risk Management Activities —
Credit Risk — Credit of Other Counterparties.
TVA’s
ability to supply power and its customers’ demands for power are influenced by
weather conditions.
Extreme
temperatures may increase the demand for power and require TVA to purchase
power
at high prices in order to meet the demand from customers, while unusually
mild
weather may result in decreased demand for power and lead to reduced electricity
sales. In addition, in periods of low rainfall or drought, TVA’s
low-cost hydroelectric generation may be reduced, requiring TVA to purchase
power or use more costly means of producing power. Furthermore, high
temperatures in the summer may limit TVA’s ability to use water from the
Tennessee or Cumberland River system for cooling at its generating facilities,
thereby limiting TVA’s ability to operate its generating
facilities. See Item 1, Business
– Weather and Seasonality
and Item 7, Management’s Discussion and Analysis of Financial Condition and
Results of Operations —
Executive Summary — Challenges During
2007
.
TVA
may incur delays and additional costs in power plant construction and may be
unable to obtain necessary regulatory approval.
TVA
has
begun the process of completing the construction of Watts Bar Nuclear Unit
2 and
may need to construct more generating facilities in the
future. The completion of such facilities involves substantial risks
of delays and overruns in the cost of labor and materials. In
addition, completion may require regulatory approval, as in the case of Watts
Bar Nuclear Unit 2. If TVA does not obtain the necessary regulatory
approval, is otherwise unable to complete the development or construction
of a facility, decides to cancel construction of a facility, or incurs
delays or cost overruns in connection with constructing a facility, TVA’s cash
flows, financial condition, and results of operations could be
negatively affected. In addition, if construction projects are
not completed according to specifications, TVA may suffer, among other
things, reduced plant efficiency and higher operating
costs. See Item 1, Business —
Nuclear
.
TVA
may face problems attracting and retaining skilled
workers.
As
TVA
employees retire and TVA faces competition for skilled workers, TVA may face
problems attracting and retaining skilled workers to, among other things,
operate and maintain TVA’s generation and transmission facilities and complete
large construction projects such as Watts Bar Nuclear Unit 2.
TVA
is involved in various legal and administrative proceedings whose outcomes
may
affect TVA’s finances and operations.
TVA
is
involved in various legal and administrative proceedings and is likely to become
involved in other legal proceedings in the future in the ordinary course of
business. Although TVA cannot predict the outcome of the individual
matters in which TVA is involved or will become involved, the resolution of
these matters could require TVA to make expenditures in excess of established
reserves and in amounts that could have a material adverse effect on TVA’s cash
flows, results of operations, and financial condition. Similarly,
resolution could require TVA to change its business practices or procedures,
which could also have a material adverse effect on TVA’s cash flows, results of
operations, and financial condition. See Item 3,
Legal
Proceedings.
TVA’s
transmission reliability could be affected by problems at other utilities or
TVA
facilities.
TVA’s
transmission facilities are directly interconnected with the transmission
facilities of neighboring utilities and are thus part of an interstate power
transmission grid. Accordingly, problems at other utilities, or at
TVA’s own facilities, may cause interruptions in TVA’s transmission
service. If TVA were to suffer a transmission service interruption,
TVA’s cash flows, results of operations, and financial condition could be
negatively affected.
Events
at non-TVA facilities which affect the supply of water to TVA’s generation
facilities may interfere with TVA’s ability to generate
power.
TVA’s
coal-fired and nuclear generation facilities depend on water from the river
systems near which they are located for cooling water and for water to convert
into steam to drive turbines. While TVA manages the Tennessee River
and large portions of its tributary system in order to provide much of this
necessary water, the U.S. Army Corps of Engineers operates and manages other
bodies of water upon which some TVA facilities rely. Events at these
non-TVA managed bodies of water or their associated hydroelectric facilities
may
interfere with the flow of water and may result in TVA having insufficient
water
to meet the needs of its plants. In such scenarios, TVA may be
required to reduce generation at its affected facilities to levels compatible
with the available supply of water. See Item 1, Business —
Power
Supply
and
Item 7, Management’s Discussion and Analysis of
Financial Condition and Results of Operations —
Executive Summary —
Challenges During 2007
.
An
incident at any nuclear facility, even one that is not owned by or licensed
to
TVA, could result in increased expenses and
oversight.
A
nuclear
incident at a TVA facility could have significant consequences including loss
of
life, damage to the environment, damage to or loss of the facility, and damage
to non-TVA property. Any nuclear incident, even at a facility that is
not owned by or licensed to TVA, has the potential to impact TVA adversely
by
obligating TVA to pay up to $90 million per year and a total of $604 million
per
nuclear incident under the Price-Anderson Act. In addition, a nuclear
incident could negatively affect TVA by, among other things, obligating TVA
to
pay retrospective premiums, reducing the availability of insurance, increasing
the costs of operating nuclear units, or leading to increased regulation or
restriction on the construction, operation, and decommissioning of nuclear
facilities.
Catastrophic
events could affect TVA’s ability to supply electricity or reduce demand for
electricity.
TVA
could
be adversely affected by catastrophic events such as fires, earthquakes, floods,
tornadoes, wars, terrorist activities, pandemics, and other similar
events. These events, the frequency and severity of which are
unpredictable, could negatively affect TVA’s cash flows, results of operations,
and financial condition by, among other things, limiting TVA’s ability to
generate and transmit power, reducing the demand for power, disrupting fuel
or
other supplies, leading to an economic downturn, or creating instability in
the
financial markets.
Demand
for electricity supplied by TVA could be reduced by changes in
technology.
Research
and development activities are ongoing to improve existing and alternative
technologies to produce electricity, including gas turbines, fuel cells,
microturbines, and solar cells. It is possible that advances in these
or other alternative technologies could reduce the costs of electricity
production from alternative technologies to a level that will enable these
technologies to compete effectively with traditional power plants like
TVA’s. To the extent these technologies become a more cost-effective
option for certain customers, TVA’s sales to these customers could be reduced,
thereby negatively affecting TVA’s cash flows, results of operations, and
financial condition.
TVA
is subject to a variety of market risks that could negatively affect TVA’s cash
flows, results of operations, and financial position.
TVA
is
subject to a variety of market risks, including, but not limited to, commodity
price risk, investment price risk, interest rate risk, and credit
risk.
•
|
Commodity
Price Risk.
Prices of commodities critical to TVA’s
operations, including coal, uranium, natural gas, fuel oil, emission
allowances, and electricity, have been extremely volatile in recent
years. If TVA fails to effectively manage its commodity price
risk, TVA’s rates could increase and thereby cause customers to look for
alternative power suppliers
|
•
|
Investment
Price Risk.
TVA is exposed to investment price risk in its
nuclear decommissioning trust, its asset retirement trust, and its
pension
fund. If the value of the investments held in the nuclear
decommissioning trust or the pension fund decreases significantly,
TVA
could be required to make substantial unplanned contributions to
these
funds, which would negatively affect TVA’s cash flows, results of
operations, and financial
condition.
|
•
|
Interest
Rate Risk.
Changes in interest rates could negatively
affect TVA’s cash flows, results of operations, and financial condition by
increasing the amount of interest that TVA pays on new bonds that
it
issues, decreasing the return that TVA receives on its short-term
investments, decreasing the value of the investments in TVA’s pension fund
and trusts, and increasing the losses on the mark-to-market valuation
of
certain derivative transactions into which TVA has
entered.
|
•
|
Credit
Risk.
TVA is exposed to the risk that its counterparties
will not be able to perform their contractual obligations. If
TVA’s counterparties fail to perform their obligations, TVA’s cash flows,
results of operations, and financial condition could be adversely
affected. In addition, the failure of a counterparty to perform
could make it difficult for TVA to perform its obligations, particularly
if the counterparty is a supplier of electricity or fuel to
TVA.

market risks.
TVA
and owners of TVA securities could be impacted by a downgrade of TVA’s credit
rating.
A
downgrade in TVA’s credit rating could have material adverse effects on TVA’s
cash flows, results of operations, and financial condition as well as on
investors in TVA securities. Among other things, a downgrade could
have the following effects:
•
|
A
downgrade would increase TVA’s interest expense by increasing the interest
rates that TVA pays on new Bonds that it issues. An increase in
TVA’s interest expense would reduce the amount of cash available for
other
purposes, which could result in the need to increase borrowings,
to reduce
other expenses or capital investments, or to increase power
rates.
|
•
|
A
significant downgrade could result in TVA’s having to post collateral
under certain physical and financial contracts that contain rating
triggers.
|
•
|
A
downgrade below a contractual threshold could prevent TVA from borrowing
under two credit facilities totaling $2.5
billion.
|
•
|
A
downgrade could lower the price of TVA securities in the secondary
market.
|

— Liquidity and Capital Resources.
TVA
may have to make significant unplanned contributions to fund its pension and
other postretirement benefit plans.
TVA’s
costs of providing pension benefits and other postretirement benefits depend
upon a number of factors, including, but not limited to:
•
|
Provisions
of the pension and postretirement benefit
plans;
|
•
|
Changing
employee demographics;
|
•
|
Rates
of increase in compensation levels;
|
•
|
Rates
of return on plan assets;
|
•
|
Discount
rates used in determining future benefit
obligations;
|
•
|
Rates
of increase in health care costs;
|
•
|
Levels
of interest rates used to measure the required minimum funding levels
of
the plans;
|
•
|
Future
government regulation; and
|
•
|
Contributions
made to the plans.
|
Any
number of these factors could increase TVA’s costs of providing pension and
other postretirement benefits and require TVA to make significant unplanned
contributions to the plans. Such contributions would negatively
affect TVA’s cash flows, results of operations, and financial
condition.
TVA
may have to make significant unplanned contributions to its nuclear
decommissioning trust.
TVA
maintains a nuclear decommissioning trust for the purpose of providing funds
to
decommission TVA’s nuclear facilities. The decommissioning trust is
invested in securities generally designed to achieve a return in line with
overall equity market performance. TVA might have to make significant
unplanned contributions to the trust if, among other things:
•
|
The
value of the investments in the trust declines
significantly;
|
•
|
The
laws or regulations regarding nuclear decommissioning change the
decommissioning funding
requirements;
|
•
|
The
assumed real rate of return on plan assets, which is currently five
percent, is lowered by the TVA
Board;
|
•
|
Changes
in technology and experience related to decommissioning cause
decommissioning cost estimates to increase significantly;
or
|
•
|
TVA
is required to decommission a nuclear plant sooner than TVA
anticipates.
|
If
TVA
makes unplanned contributions to the trust, the contributions would negatively
affect TVA’s cash flows, results of operations, and financial
condition.
TVA
may be unable to meet its current cash requirements if its access to the debt
markets is limited.
TVA’s
cash management policy is to use cash provided by operations together with
proceeds from power program borrowings and a $150 million note with the U.S.
Treasury to fund TVA’s current cash requirements. In addition, TVA
has access to $2.5 billion of credit facilities with a national
bank. In light of TVA’s cash management policy, it is critical that
TVA continue to have access to the debt markets in order to meet its cash
requirements. The importance of having access to the debt markets is
underscored by the fact that TVA, unlike many utilities, relies almost entirely
on the debt markets to raise capital since it is not authorized to issue equity
securities. See Item 7, Management’s Discussion and Analysis of
Financial Condition and Results of Operations —
Liquidity and Capital
Resources.
Approaching
or reaching its debt ceiling could limit TVA’s ability to carry out its
business.
At
September 30, 2007, TVA had approximately $22.5 billion of Bonds outstanding
(not including noncash items of foreign currency valuation loss of $299 million
and net discount on sale of bonds of $189 million). TVA has a
statutorily imposed ceiling of $30 billion on outstanding
Bonds.
Approaching or reaching this debt ceiling could
adversely affect TVA’s business by limiting TVA’s ability to borrow money and
increasing the cost of servicing TVA’s debt. In addition, approaching
or reaching this debt ceiling could lead to increased legislative or regulatory
oversight of TVA’s activities. See Item 7, Management’s Discussion
and Analysis of Financial Condition and Results of Operations —
Legislative
and Regulatory Matters — Proposed Legislation.
TVA’s
cash flows, results of operations, and financial condition could be negatively
affected by economic downturns.
Sustained
downturns or weakness in the economy in TVA’s service area or other parts of the
United States could reduce overall demand for power and thus reduce TVA’s power
sales and cash flows, especially as TVA’s industrial customers reduce their
operations and thus their consumption of power.
TVA’s
financial control system cannot guarantee that all control issues and instances
of fraud will be detected.
No
financial control system, no matter how well designed and operated, can provide
absolute assurance that the objectives of the control system are met, and no
evaluation of financial controls can provide absolute assurance that all control
issues and instances of fraud can be detected. The design of any
system of financial controls is based in part upon certain assumptions about
the
likelihood of future events, and there can be no assurance that any design
will
succeed in achieving its stated goals under all potential future conditions,
regardless of how remote. See Item 9A, Controls and Procedures for
TVA’s assessment of its internal controls as of September 30, 2007.
TVA
could lose the ability to use regulatory accounting and be required to write
off
a significant amount of regulatory assets.
TVA
is
able to use regulatory accounting because it satisfies the requirements set
forth in Statement of Financial Accounting Standards (“SFAS”) No. 71,
“Accounting for the Effects of Certain Types of
Regulation.”
Accordingly, TVA records as assets certain costs
that would not be recorded as assets under generally accepted accounting
principles for non-regulated entities. As of September 30, 2007, TVA
had $4.7 billion of regulatory assets. If TVA loses its ability to
use regulatory accounting, TVA could be required to write-off its regulatory
assets. Any asset write-offs would be required to be recognized in
earnings in the period in which regulatory accounting under SFAS No. 71 ceased
to apply to TVA.
Payment
of principal and interest on TVA securities is not guaranteed by the United
States.
Although
TVA is a corporate agency and instrumentality of the United States government,
TVA securities are not backed by the full faith and credit of the United
States. Principal and interest on TVA securities are payable solely
from TVA’s net power proceeds. Net power proceeds are defined as the
remainder of TVA’s gross power revenues after deducting the costs of operating,
maintaining, and administering its power properties and payments to states
and
counties in lieu of taxes, but before deducting depreciation accruals or other
charges representing the amortization of capital expenditures, plus the net
proceeds from the sale or other disposition of any power facility or interest
therein.
The
trading market for TVA securities might be limited.
All
of
TVA’s Bonds are listed on the New York Stock Exchange except for TVA’s discount
notes, which have maturities of less than one year, and the power bonds issued
under TVA’s electronotes
®
program,
which is
TVA’s medium-term note program. In addition, some of TVA’s Bonds are
listed on foreign stock exchanges. Although many of TVA’s Bonds are
listed on stock exchanges, there can be no assurances that any market will
develop or continue to exist for any Bonds. Additionally, no
assurances can be made as to the ability of the holders of Bonds to sell their
Bonds or the price at which holders will be able to sell their
Bonds. Future trading prices of Bonds will depend on many factors,
including prevailing interest rates, the then-current ratings assigned to the
Bonds, the amount of Bonds outstanding, the time remaining until the maturity
of
the Bonds, the redemption features of the Bonds, the market for similar
securities, and the level, direction, and volatility of interest rates
generally.
If
a
particular series of Bonds is offered through underwriters, those underwriters
may attempt to make a market in the Bonds. The underwriters would not
be obligated to do so, however, and could terminate any market-making activity
at any time without notice.
In
addition, legal limitations may affect the ability of banks and others to invest
in Bonds. For example, national banks may purchase TVA Bonds for
their own accounts in an amount not to exceed 10 percent of unimpaired
capital and surplus. Also, TVA Bonds are “obligations of a
corporation which is an instrumentality of the United States” within the meaning
of section 7701(a)(19)(C)(ii) of the Internal Revenue Code for purposes of
the
60 percent of assets limitation applicable to U.S. building and loan
associations.
Not
applicable.
