Federal Power: Regional Effects of Changes in PMAs' Rates (Letter Report,
11/16/98, GAO/RCED-99-15).
Pursuant to a congressional request, GAO provided a state-by-state
analysis of the preference customers who buy power from the Southeastern
Power Administration, the Southwestern Power Administration, and the
Western Area Power Administration, focusing on the: (1) extent to which
preference customers' rates may change if market rates are charged; (2)
areas the three power marketing administrations' (PMA) preference
customers report serving; and (3) incomes in these areas and the extent
to which they are rural or urban.
GAO noted that: (1) overall, slightly more than two-thirds of the
preference customers that purchase power directly from the Southeastern,
Southwestern, and Western Area power administrations may see relatively
small or no rate increases if these PMAs begin to charge market rates
for the power they produce; (2) in particular, given GAO's assumptions,
almost all of Southeastern's preference customers would see average rate
increases of up to one-half cent per kilowatt hour (kWh) on rates that
in 1995 typically ranged from 3.5 to 6.0 cents per kWh; (3) most of
these preference customers would see increases of less than one-tenth
cent per kWh; (4) if the preference customers served by Southeastern
pass the higher rates on proportionally to their residential end users,
most end users would see their monthly electricity bill increase by less
than $1, while the maximum increase would range in most states between
$1 and $8, depending on the state; (5) preference customers who receive
power from Western may see a variety of rate increases if market rates
are charged; (6) as a group, Southwestern's preference customers may see
rate increases that lie between those for Southeastern's and Western's
customers; (7) most of Southwestern's preference customers may see
relatively low rate increases of up to one-half cent per kWh on rates
that typically ranged between 1.5 and 3.5 cents per kWh; (8) however,
almost all preference customers in Oklahoma may see larger rate
increases that exceed 1.5 cents per kWh; (9) in general, a preference
customer's rate increase depends primarily on what portion of its total
power comes from the PMA and how close the PMA's rate is to the market
rate; (10) preference customers included in GAO's analysis that
purchased power directly from the PMAs serve varying portions of 29
states; (11) the populations in the areas preference customers serve
generally have median incomes that are similar to the median income in
the entire state; (12) in about two-thirds of the states GAO examined,
the preference customers serve counties and towns whose median household
incomes are within 15 percent of the statewide median income; (13)
however, in some states, preference customers primarily serve poorer
areas and households; (14) nationwide, about half of the towns that
preference customers serve are urban and about half are rural; and (15)
most of the counties are mixed, about 40 percent are rural, and the
remainder are urban.

November 16, 1998
The Honorable Don Young
Chairman, Committee on Resources
House of Representatives
The Honorable John T. Doolittle
Chairman, Subcommittee on Water and Power
Committee on Resources
House of Representatives
Since the New Deal, the federal government has established about 130
water projects that--in addition to promoting agriculture, flood
control, navigation, and other activities--produce electric power.
To provide this power to large portions of rural America, the
government also created five power marketing administrations (PMA),
along with the Tennessee Valley Authority (TVA).\1 These facilities
have been part of the electrification of America, especially rural
America. In 1940, about 25 percent of all households lacked
electricity and 70 percent of farms, whereas today, virtually all
households have electricity.
Now that nearly all of America has electricity, some believe the PMAs
have completed their mission and should be divested, particularly
since greater competition exists in the electricity industry. Others
suggest that the PMAs be required to operate in ways more like
private utilities' practices, such as charging market rates for
power.\2 However, the PMAs currently sell wholesale power to entities
such as cooperatives and publicly owned utilities, also known as
"preference customers," at average rates that, from 1990 to 1995,
were from 40 to 50 percent below the rates nonfederal utilities
charged. Although preference customers generally buy most of their
power from sources other than the PMAs and, as a result, currently
pay market rates for that power, concerns have been raised that a
change in PMAs' ownership or the means by which they establish rates
could increase rates and could adversely affect the rural or poorer
areas they serve. Those expressing such concerns believe that the
PMAs should continue to operate as they do now. To date, it has been
difficult to examine the possible impact of potential rate increases
because few analyses have identified the places that ultimately
consume PMA power or the characteristics of the households the
preference customers serve.
To aid in congressional deliberations on the future role of the PMAs,
as requested we are providing a state-by-state analysis of the
preference customers who buy power from the Southeastern Power
Administration (Southeastern), the Southwestern Power Administration
(Southwestern), and the Western Area Power Administration
(Western).\3
More specifically, we identify (1) the extent to which preference
customers' rates may change if market rates are charged, (2) the
areas the three PMAs' preference customers report serving, and (3)
the incomes in these areas and the extent to which they are rural or
urban.
--------------------
\1 TVA is a multipurpose independent federal corporation. Among its
purposes is generating power, which, like the PMAs, it markets. TVA
sells power in nearly all of Tennessee, as well as parts of Alabama,
Georgia, Kentucky, Mississippi, North Carolina, and Virginia. App.
I presents a map of TVA's service territory.
\2 Our report Federal Power: Options for Selected Power Marketing
Administrations' Role in a Changing Electricity Industry
(GAO/RCED-98-43, Mar. 6, 1998) identifies options that the Congress
and other policymakers could pursue to address concerns about the
PMAs' role in restructured markets or to manage them in a more
businesslike fashion. Among other options, the report discusses
divestiture and its potential impact on preference customers by
individual PMA.
\3 In addition, the Bonneville Power Administration (Bonneville), the
oldest PMA and the largest in terms of total revenues, operates in
the Pacific Northwest. Because you asked us to examine Southeastern,
Southwestern, and Western, Bonneville is not covered by this report.
Finally, the projects constituting the Alaska Power Administration,
the smallest PMA, were fully divested in October 1997 and August
1998.
BACKGROUND
------------------------------------------------------------ Letter :1
The Department of Energy's (DOE) PMAs sell power primarily to
preference customers--cooperatives and public bodies, such as
municipal utilities, irrigation districts, and military
installations--that are located in the PMAs' service territories.\4
Many of these preference customers then resell the power to
industrial, commercial, and/or residential end-users.
To estimate any potential rate changes if market rates are charged
(after a divestiture of the PMAs or otherwise), we calculated how
much, in cents per kilowatthour (kWh),\5 each preference customer
paid, on average, for power purchased from (1) all sources, including
the PMAs, and (2) sources other than the PMAs, including the
wholesale market, in 1995.\6 Then, we took the difference between
these two, considering the latter to be the market rate. To map the
areas that preference customers serve, we identified the counties and
towns that the customers reported serving in Electrical World:
Directory of Electric Power Producers.\7 It is important to note that
our analysis included only those customers that purchased power
directly from the PMAs and that our analysis shows higher rate
increases than would be likely if market rates decline. To develop
information on the characteristics of the areas that preference
customers reported serving, for each county and town we obtained data
on 1989 household incomes and the extent to which the population is
urban or rural, as reported in the 1990 census, the latest data
available. Appendix III provides additional details on our scope and
methodology.
--------------------
\4 Our analysis covers about 680 preference customers included in the
Energy Information Administration's Form 861 database of electric
utilities, which is a compendium of utilities in the United States.
As a result, we did not include other preference customers such as
those owned by state governments or the federal government--for
example, hospitals and military facilities. App. II presents a map
of the PMAs' service territories. As explained in app. III, we did
not include TVA as a customer of Southeastern.
\5 A watt is the basic unit used to measure electric power. A
watthour is equal to a watt of power applied for 1 hour. A
kilowatthour is 1,000 watthours. A megawatthour is a 1,000 kWh.
\6 We based our work on an existing database developed for an earlier
GAO report, which compiled information on 1995 purchases. Comparable
data for 1996 or later were not available.
\7 Electrical World: Directory of Electric Power Producers is a
standard reference for data on the electricity industry. It compiles
specific data on subjects such as individual utilities' power
production capacities, power sales, sources of purchased power,
distribution facilities, as well as the service areas, which are
provided by the utilities themselves. However, it is important to
note that under the directory's reporting format, preference
customers specify the counties and/or towns they serve, which may not
precisely portray the boundaries of their service areas. For
example, although a preference customer may report serving a
particular county, it may actually serve a portion of the county.
Consequently, although our approach may somewhat overstate the areas
preference customers serve, it is based on the best data available.
RESULTS IN BRIEF
------------------------------------------------------------ Letter :2
Overall, slightly more than two-thirds of the preference customers
that purchase power directly from the Southeastern, Southwestern, and
Western Area power administrations may see relatively small or no
rate increases if these PMAs begin to charge market rates for the
power they produce. In particular, given our assumptions, almost all
of Southeastern's preference customers would see average rate
increases of up to one-half cent per kWh on rates that in 1995
typically ranged from 3.5 to 6.0 cents per kWh. Most of these
preference customers would see increases of less than one-tenth cent
per kWh. If the preference customers served by Southeastern pass the
higher rates on proportionally to their residential end-users, most
end-users would see their monthly electricity bill increase by less
than $1, while the maximum increase would range in most states
between $1 and $8, depending on the state. Preference customers who
receive power from Western may see a variety of rate increases if
market rates are charged. In California, Colorado, and Nebraska, for
example, more than three-quarters of the preference customers may see
relatively small increases of less than one-half cent per kWh.
However, in several other states, such as South Dakota and Utah, a
number of preference customers may see average rate increases that
exceed 1.5 cents per kWh. These customers of Western typically paid
relatively low rates ranging from 1.5 to 3.0 cents per kWh and bought
most of or all their power from the PMA in 1995. In turn,
residential end-users who receive power from these utilities may see
larger increases in their electricity bills. For example, in states
with larger rate increases, if a preference customer's rate increases
by 1.5 cents per kWh, residential end-users would pay about $10 to
$15 more per month for electricity, depending on the state. As a
group, Southwestern's preference customers may see rate increases
that lie between those for Southeastern's and Western's customers.
Most of Southwestern's preference customers may see relatively low
rate increases of up to one-half cent per kWh on rates that typically
ranged between 1.5 and 3.5 cents per kWh. However, almost all
preference customers in Oklahoma may see larger rate increases that
exceed 1.5 cents per kWh. For most of these customers, their
residential end-users would see monthly increases of about $22. In
general, then, a preference customer's rate increase depends
primarily on what portion of its total power comes from the PMA and
how close the PMA's rate is to the market rate.
Preference customers included in our analysis that purchased power
directly from the PMAs\8 serve varying portions of 29 states.\9 In
most states, the areas that preference customers report serving cover
less than half the state. In several states--such as Illinois,
Kentucky, and Montana, which are served by fewer than five preference
customers--the areas covered are even smaller. In contrast, in
several states, particularly Arizona, Georgia, North Carolina, and
South Dakota, preference customers report serving most or almost all
counties in the state. Except in Colorado, North Dakota, and South
Dakota, the preference customers provide less than 10 percent of the
residential end-users' electricity consumption.
The populations in the areas preference customers serve generally
have median incomes that are similar to the median income in the
entire state. In about two-thirds of the states we examined, the
preference customers serve counties and towns whose median household
incomes are within 15 percent of the statewide median income.
However, in some states, such as Montana and Texas, preference
customers primarily serve poorer areas and households. Yet in other
states, such as California, preference customers sell PMA power to
areas such as Orange County, where nearly half of the households have
incomes exceeding $50,000 a year--or at least 38 percent greater than
the statewide median. Nationwide, about half of the towns that
preference customers serve are urban and about half are rural. Most
of the counties are "mixed" (neither urban nor rural), about 40
percent are rural, and the remainder are urban.
--------------------
\8 We did not include in our analysis customers that receive PMA
power indirectly, that is, through direct preference customers of the
PMAs--generation and transmission cooperatives and municipal joint
action agencies--because, with very few exceptions, the PMAs' 1995
annual reports do not list them.
\9 These states are Alabama, Arizona, Arkansas, California, Colorado,
Florida, Georgia, Illinois, Iowa, Kansas, Kentucky, Louisiana,
Minnesota, Mississippi, Missouri, Montana, Nebraska, New Mexico,
Nevada, North Carolina, North Dakota, Oklahoma, South Carolina, South
Dakota, Texas, Utah, Virginia, Wisconsin, and Wyoming.
MOST RATE INCREASES MAY BE
RELATIVELY SMALL, ALTHOUGH SOME
MAY BE LARGER
------------------------------------------------------------ Letter :3
Overall, about 68 percent of Southeastern's, Southwestern's, and
Western's preference customers may experience relatively small rate
increases. In our analysis, the increases that we considered
relatively small (0.5 cent per kWh or less), moderate (from greater
than 0.5 cent up to 1.5 cents), and relatively large (greater than
1.5 cents) represent amounts above the average rates that preference
customers paid for power from all sources (both PMAs and others) in
1995. These base rates typically ranged in 1995 from 3.5 to 6.0
cents for Southeastern's preference customers, from 1.5 to 3.5 cents
for Southwestern's preference customers, and from 1 to 4 cents for
Western's preference customers. The increases represent the
difference between these average rates and what preference customers
would have to pay if they purchased all of their power at market
rates. For example, if a preference customer of Southeastern paid a
combined 3.5 cents per kWh for power from the PMA and other sources
in 1995 and paid 3.9 cents for power from non-PMA sources, we assumed
the customer's rates would rise from 3.5 to 3.9 cents--a relatively
small increase of 0.4 cent--if it had to pay market rates for all its
power. Our calculation of the increase in a residential end-user's
monthly electricity bill represents the amount of the preference
customer's increase times the average monthly consumption of
electricity by residential end-users in the preference customer's
state.
As shown in figure 1, 98 percent of Southeastern's preference
customers may see relatively small rate increases of 0.5 cent per kWh
or less if they pay market rates for PMA power. For Western and
Southwestern, about half of their preference customers would see
relatively small rate increases and about 25 to 30 percent of the
customers for each PMA would see relatively large increases. Figure
2 breaks out these potential increases by state and, of the total
amount of power consumed in each state, indicates the percentage
provided by the PMA.
Figure 1: Potential Changes in
Preference Customers' Rates if
the PMAs Charge Market Rates
(See figure in printed
edition.)
Note: Power from the preference customers represents about 2 percent
of the total electricity consumption for the 29 states in our
analysis.

Administration and Southeastern's, Southwestern's, and Western's 1995
annual reports.

Preference Customers' Rates in
Each State and the PMAs' Shares

Consumption
(See figure in printed

Note: We did not include Southeastern's sales to TVA, as described
in app. III. The figure also excludes any power purchased from the
Bonneville Power Administration.
Source: GAO's analysis of data provided by DOE's Energy Information
Administration and Southeastern's, Southwestern's, and Western's 1995
annual reports
As shown in figure 2, in virtually every state Southeastern serves,
at least 85 percent of the preference customers may see relatively
small rate increases.\10 Slightly more than half of the PMA's
preference customers may see increases of less than 0.1 cent per kWh.
If these preference customers pass their rate increases through
proportionally to the residential end-users they serve, the
residential end-users would see their average monthly electricity
bill increase by $1 or less. In most of Southeastern's states, the
maximum increase that a preference customer would pass on to its
residential end-users ranges between $1 and $8 per month, depending
on the state. The only relatively large rate increase for a
preference customer served by Southeastern may be in Illinois, which
has one preference customer.
In states served by Western, preference customers may see a variety
of rate increases.\11
For example, as shown in figure 2, over 75 percent of the preference
customers in California, Colorado, and Nebraska may experience
relatively small rate increases. In these three states, residential
end-users served by most preference customers would see less than
$2.50 increases in their average monthly electricity bills. However,
a significant number of Western's preference customers may see
moderate increases. As shown in figure 2, at least 25 percent of the
preference customers in many Western states, such as Iowa, Minnesota,
and South Dakota, may experience average rate increases from greater
than 0.5 cent up to 1.5 cents per kWh. If these preference customers
proportionally pass these costs along to their residential end-users,
the end-users would pay from $3 to $14 more in their average monthly
electric bills, depending on the state.
Finally, in several states served by Western, a number of preference
customers may see average rate increases that exceed 1.5 cents per
kWh. For example, 60 percent of the preference customers in South
Dakota and 33 percent of the customers in Utah may see rate increases
exceeding 1.5 cents per kWh. In turn, residential end-users who
receive power from these utilities would see larger increases in
their electricity bills. For example, in states with larger rate
increases,\12 if a preference customer's rate increases by 1.5 cents
per kWh, residential end-users would pay about $10 to $15 more per
month for electricity, depending on the state. Preference customers
who may see these larger increases typically paid relatively low
rates, ranging from 1.5 to 3.0 cents per kWh and bought most or all
of their power from Western.
Taken together, Southwestern's preference customers may experience
higher rate increases than Southeastern's customers but lower
increases than Western's.\13 As shown in figure 2, in most of
Southwestern's states, a majority of the preference customers may see
relatively small increases of 0.5 cent per kWh or less on base rates
that typically ranged from 1.5 to 3.5 cents. In turn, residential
end-users that receive power from most of Southwestern's preference
customers' would see their electricity bills increase by less than $3
a month. However, in Oklahoma, 79 percent of the preference
customers may see larger increases that exceed 1.5 cents per kWh.
Most of these customers paid less than 1.5 cents per kWh--less than
half the 1995 national average market rate--and purchased all of
their power from Southwestern. Residential end-users of these
preference customers typically would pay about $22 more in their
average monthly electricity bills.
As we discussed in our March 1998 report, it is important to remember
that in many cases where rate increases may be relatively large
(greater than 1.5 cents per kWh), the preference customers paid about
1 to 1.5 cents per kWh in 1995 for PMA power. These rates on average
were about 2.5 to 3 cents per kWh lower than what utilities paid in
the private market nationwide. Conversely, in many cases where rate
increases may be relatively small, that is, 0.5 cent per kWh or less,
preference customers generally paid rates close to the market rates.
If market rates are charged (after a PMA divestiture or
otherwise),\14 preference customers would pay the same rates as
utilities that lack access to PMA power. As we discussed in our
March 1998 report, if the Congress chose to change the status quo
regarding rates, it could mitigate the size of potential rate
increases by using several approaches, such as establishing rate
caps.
A preference customer's rate increase also depends on what portion of
its total power comes from the PMA. Generally, the less a preference
customer relies on a PMA's power, the less the rate increase may be.
Preference customers in states served by Southeastern may experience
small increases because they purchase a small portion of their power
from the PMA. In 1995, 99 percent of Southeastern's preference
customers purchased less than 25 percent of their power from the PMA.
Overall, most preference customers purchase a majority of their power
from sources other than the PMAs and, as a result, currently pay
market rates for that power. In contrast, preference customers that
purchase a large portion of their power from a PMA are more likely to
experience larger increases. For example, among the 60 percent of
the preference customers in South Dakota that may experience rate
increases of at least 1.5 cents per kWh if market rates are charged,
most bought over 70 percent of their power from the PMA in 1995.
Overall, PMA power represented about 23 percent of South Dakota's
total electricity consumption in 1995. Usually, preference customers
that rely on a PMA for most or all of their power are smaller
utilities that deliver 100,000 megawatthours or less to their
end-users annually.\15
It is important to also note that because our estimates of potential
rate increases are based on market rates in 1995, our methodology is
conservative. If prices for wholesale power decline in the future,
as many industry analysts and DOE officials believe they will,
customers' rate increases generally will be smaller than our
estimates.
Finally, the likely rate increases we discuss--from relatively small
to relatively large, if the preference customers pay market rates for
PMA power--would usually affect a relatively small portion of the
power consumed in each state, as shown by the shading or patterns in
the states in figure 2. We found that the portion of the total power
consumed in a state that was provided by the three PMAs was generally
relatively small. For example, the PMAs provided 5 percent or less
of the total power consumption in 22 of the 29 states in our
analysis. The average for the 29 states was 2 percent.
--------------------
\10 Southeastern's preference customers are located in Alabama,
Florida, Georgia, Illinois, Kentucky, Mississippi, North Carolina,
South Carolina, and Virginia. As mentioned, a map showing each PMA's
service territory is included in app. II.
\11 Western's preference customers are located in Arizona,
California, Colorado, Iowa, Minnesota, Montana, Nebraska, New Mexico,
Nevada, North Dakota, South Dakota, Utah, Wisconsin, and Wyoming. In
Kansas, Missouri, and Texas, most preference customers purchase power
from Southwestern, although a few purchase power from Western.
\12 These are states where 33 percent or more preference customers
may see rate increases of 1.5 cents per kWh or greater.
\13 Southwestern's preference customers are located in Arkansas,
Kansas, Louisiana, Missouri, Oklahoma, and Texas.
\14 In commenting on our draft report, DOE stated that market rates
would not necessarily be charged if a PMA is divested to a public
utility.

PREFERENCE CUSTOMERS SERVE
VARYING PORTIONS OF MANY STATES
------------------------------------------------------------ Letter :4
As shown in figure 3, preference customers that are directly served
by Southeastern, Southwestern, and Western reported serving varying
portions of 29 states across the nation. We did not include
customers that receive PMA power indirectly, that is, through direct
preference customers of the PMAs--generation and transmission
cooperatives and municipal joint action agencies--because, with very
few exceptions, the PMAs' 1995 annual reports do not list them.
Figure 3: Potential Areas
Directly Served by Preference
Customers of Southeastern,
Southwestern, and Western
(See figure in printed
edition.)
Notes: Preference customers may actually provide power to only
portions of the counties and/or towns they report serving. Under the
reporting format of Electrical World, preference customers are asked
to cite the counties and/or towns they serve, as opposed to the
specific geographic boundaries of their service areas. In many
cases, several utilities report serving the same county and the
actual service area may be smaller than the areas they report
serving. App. IV contains, for each state, a map depicting the
counties and towns reported by the customers that reported receiving
power directly from the PMA, followed by a complete list of those
locations.
Our map includes only the counties and towns that preference
customers serve directly and does not include preference customers
such as generation and transmission cooperatives or municipal joint
action agencies, who buy PMA power and then resell it to other
publicly owned utilities. The annual reports for Southeastern and
Western do not include these utilities as customers, while
Southwestern's does in two cases.
Sources: GAO's analysis of data provided by Southeastern's,
Southwestern's, and Western's 1995 annual reports and Electrical
World: Directory of Electric Power Producers (1997 ed.).
As the figure shows, in most states, the areas the preference
customers reported serving directly cover less than half the state.
For example, very small portions of Arkansas, Louisiana, and Missouri
are served by preference customers. In some cases, small areas are
served in part because only a few preference customers directly serve
the state. For example, Illinois and Wisconsin have only one
preference customer to serve residential end-users, while Kentucky
and Montana have three. Other states have more preference customers,
but in some cases they serve counties and towns that are concentrated
in portions of the state. For example, South Carolina's 26
preference customers reported serving areas almost exclusively in the
northwestern corner of the state. The seven preference customers in
Wyoming reported serving four counties, which are clustered in the
southwestern and south central portions of the state and two towns
but no other areas in the rest of the state. Similarly, the eight
preference customers in Texas reported serving 17 counties in the
south central part of the state and five towns in eastern Texas but
did not serve the rest of the state.
Additionally, as depicted in figure 3, large portions of several of
Southeastern's and Western's states receive service directly from
preference customers. For example, preference customers reported
serving almost every county in Georgia and most of the counties in
North Carolina and Virginia. In these states, many counties received
service from two or more preference customers. In Nebraska,
preference customers reported serving over 130 towns located around
the state.
Finally, regardless of their geographic coverage, we found, as shown
in figure 2, that the preference customers generally provided a
relatively small portion of the total power consumed in each state.
IN INCOME, END-USERS ARE
SIMILAR TO THE POPULATION OF
THE ENTIRE STATE; MOST SERVICE
AREAS ARE EITHER URBAN OR
"MIXED"
------------------------------------------------------------ Letter :5
Although preference customers serve areas with incomes lower than the
national average, most of the households they serve have incomes that
are similar to those in the entire state. As shown in figure 4, in
21 of 28
states,\16 households in the counties and towns preference customers
report serving had median incomes within 15 percent of the statewide
median income, as reported in the 1990 census.
Figure 4: Proximity of Median
Incomes in Preference
Customers' Reported Service
Areas and the Entire State
(See figure in printed
edition.)
Sources: GAO's analysis of data provided by Southeastern's,
Southwestern's, and Western's 1995 annual reports; Electrical World:
Directory of Electric Power Producers (1997 ed.); and 1989 data
provided by the Census Bureau.
In some states, the median incomes of the end-users and statewide are
close because almost every county in the state receives power from
preference customers. For example, in Georgia, preference customers
reported serving 151 of the state's 159 counties. Furthermore, the
distribution of income for households receiving PMA power generally
mirrors the distribution of household income in the entire state.
For example, in Alabama, about 35 percent of the households in
preference customers' service areas had annual incomes of less than
$15,000 in 1989, while 24 percent had incomes exceeding $40,000.
Similarly, in the entire state, 33 percent of the households had
annual incomes under $15,000, and 26 percent had annual incomes
exceeding $40,000. This compares with the 1995 national average
household income of $35,004.
However, in a few cases, preference customers serve areas that are
significantly poorer than the remainder of the state. For example,
in 1989 in Texas, the median income of the households preference
customers served was almost 40 percent lower than median household
income of $27,016 in the entire state. In preference customers'
service areas, over 45 percent of the households had annual incomes
smaller than $15,000, compared with 28 percent of the households in
the entire state. Similarly, in Montana, preference customers served
households with median incomes 20 percent, or about $4,500, below the
state median of $22,988. In commenting on our draft report, DOE
officials noted that the PMAs also provide a valuable service to
Indian reservations, which are among the poorest areas of the nation.
Our analysis shows, for example, that about 53 percent of the
households in Shiprock, New Mexico, which is located on the Navajo
Indian Reservation, had median incomes of less than $15,000, compared
with about 31 percent statewide.
In contrast, preference customers in some states send PMA power to a
number of counties and towns where a large portion of the households
have relatively high incomes. For example, in California, preference
customers reported serving areas in the southern part of the state
such as Orange County, where about 45 percent of the households had
incomes in 1989 exceeding $50,000--at least 40 percent higher than
the state median income of $35,798. In the northern part of the
state, preference customers reported serving Palo Alto, where 55
percent of the households had incomes exceeding $50,000. Throughout
California, about 45 percent of the households in areas preference
customers reported serving had annual incomes exceeding $40,000.
Similarly, in Colorado, about 33 percent of the households in Aspen
had 1989 incomes that exceeded $50,000 or at least 65 percent greater
than the state median income of $30,140.
We estimate that, overall, about 53 percent of the towns that
preference customers reported serving are urban.\17 States where most
of the towns are urban include California, Georgia, and North
Carolina. In addition, about 47 percent of the towns preference
customers reported serving are rural. States where large numbers of
these towns are rural include Florida, Iowa, and Nebraska. Less than
1 percent of the towns are "mixed"--that is, they have populations
that are neither urban nor rural. Most counties that preference
customers reported serving, or about 52 percent, are mixed. Alabama
and South Carolina, for example, have high percentages of mixed
counties. About 39 percent of the counties are rural, about 9
percent of the counties are urban. North Dakota and South Dakota
have large proportions of rural counties.
Finally, although preference customers sell PMA power in many less
densely populated areas, most of the households they serve are
located in a small number of more urbanized places. This suggests
that most PMA power is consumed by customers in more highly urbanized
places. For example, although preference customers reported serving
150 counties in Georgia, 11 of those counties contain over half of
the households in the areas preference customers reported serving.
--------------------
\16 We did not include median income data for Wisconsin because the
one preference customer in this state does not provide retail service
to residential end-users.
\17 We classified a county or town as urban or rural if at least 80
percent of its population is defined as urban or rural by the Census
Bureau. The Census Bureau generally considers an area to be urban if
its population is 2,500 or more. If a county or town is less than 80
percent urban or rural, we classified it as "mixed."
AGENCY COMMENTS
------------------------------------------------------------ Letter :6
We provided copies of a draft of this report to DOE for its review
and comment. We received comments from DOE's Power Marketing Liaison
Office, which is responsible for Southeastern, Southwestern, and
Western, and have included its comments and our responses as appendix
V.
DOE commented that our data sources were flawed because we relied on
incomplete and/or inaccurate data and that it was impossible to have
confidence in conclusions drawn from analysis of the data. To
address each of our objectives, our analyses used data reported by
the PMAs and their preference customers--data that we believe to be
the best available. DOE recognizes that obtaining complete data on
the electric utility industry is not easy. We believe that we used
the data appropriately to satisfy the objectives of our review and
that our methodology is sound. However, we agree that the data we
used have limitations, and we have pointed out the limitations in our
report. Many of the concerns that DOE expressed do not deal with the
data we used but with the definition of a preference customer of a
PMA. DOE stated that our analyses omitted generation and
transmission cooperatives, their members, and municipal joint action
agencies. For our analysis, we included only the preference
customers who purchased power directly from the PMAs--as listed in
the PMAs' 1995 annual reports. We did not include generation and
transmission cooperatives, their members, or municipal joint action
agencies because the annual reports of two of the three
PMAs--Southeastern and Western--do not include them in their lists of
customers. Because Southeastern and Western together represent over
90 percent of the total preference customers of the three PMAs, we
used their approach. If our rate analysis had included the utilities
that indirectly buy PMA power through preference customers, the rate
increases for these utilities would have been, at most, the same as
the increases for the preference customers. For our analysis of
urban/rural populations, we used the counties and towns that the
preference customers that were included in our rate analysis reported
to Electrical World: Directory of Electric Power Producers. We
acknowledge that the data in Electrical World may not match the
actual service territories. However, we used these data because they
were reported by the preference customers and were the best
available.
DOE also stated that using 1995 data does not reflect today's market
situation. As the electricity market continues to evolve, many
industry experts believe that market rates for wholesale power have
declined since 1995 and will fall farther. If market rates fall more
than the PMAs' rates, our estimates of rate increases will prove to
be overstated. We have seen no evidence that the PMAs' overall rates
have fallen more than rates in the wholesale market. DOE also
commented that more balance was needed in our report because the
report goes beyond reporting data and does not present all opposing
points of view. We believe that our report is balanced and that,
throughout the report, we present a neutral description of our
objectives and findings. Nevertheless, we have added additional
detail to our report, such as including all options for the PMAs'
future role in the changing electricity market and noting that a PMA
provides power to Native American households with low incomes.
We met with officials from the American Public Power Association\18
and National Rural Electric Cooperative Association,\19 which are
national representatives of the PMAs' preference customers, and
discussed the methodology we used to perform our analysis and the
results we obtained. On our rate analysis, the officials commented
that certain preference customers may see larger rate increases than
what we estimated because, to replace the power they buy from the
PMAs, they would pay more than what they paid for non-PMA power in
1995. The officials also commented that, although we classified many
of the rate increases as relatively small, these increases could
nonetheless have significant economic impacts on preference customers
or their end-users. However, these officials said that they could
not provide more detailed comments until they and the members of
their organizations had an opportunity to review the final report and
its appendixes.
We also met with representatives of the Edison Electric Institute\20
and discussed the methodology we used to perform our analysis and the
results we obtained. They commented that our analysis was credible,
although they suspected that it could have overstated the rate
increases that may occur because competition is increasing and market
rates for electricity have been declining. They believe that the
impact of the preference customers' paying market prices for power
would be quite modest. They also commented that, if the wholesale
rate impacts were translated to the prices that the ultimate consumer
would see, the impacts would be even less.

TENNESSEE VALLEY AUTHORITY'S
SERVICE AREA
=========================================================== Appendix I
The Tennessee Valley Authority (TVA) sells power to 159 municipal and
cooperative distributors and to a number of directly served large
industrial customers and federal agencies. As shown in figure I.1,
TVA sells power to customers located in Tennessee and parts of six
other states in the Southeast. According to the Southeastern Power
Administration (Southeastern), TVA purchased nearly 1.9 billion
kilowatthours (kWh) of electricity from the PMA in fiscal year 1995
and over 2.9 billion kWh of electricity in fiscal year 1996 for
resale to TVA's municipal and cooperative distributors. However, as
described in appendix III, we did not include Southeastern's sales to
TVA in our analysis.

========================================================== Appendix II
As figure II.1 shows, according to the Department of Energy (DOE),
its power marketing administrations (PMA) serve preference customers
located in all or parts of 34 states.

OBJECTIVES, SCOPE, AND METHODOLOGY
========================================================= Appendix III
Since the New Deal, the federal government has established about 130
water projects that--in addition to promoting agriculture, flood
control, navigation, and other activities--produce electric power.
To sell this power to large portions of rural America, the federal
government created five PMAs and TVA.
Now that nearly all of America has electricity, some believe the PMAs
have completed their mission and should be divested. Others suggest
that the PMAs be required to charge market rates for power. However,
since PMAs have historically served rural areas, concerns have been
raised that a change in PMAs' ownership or the means by which they
establish rates could adversely affect the rural or poorer areas they
serve. Yet few analyses to date have identified the places that
ultimately consume PMA power or the characteristics of the households
the preference customers serve.
To aid in congressional deliberations on the future role of the PMAs,
you requested that we provide a state-by-state analysis of the
preference customers who buy power from Southeastern, Southwestern,
and Western. More specifically, you asked that we identify (1) the
extent to which preference customers' rates may change by state if
market rates are charged, (2) the areas the three PMAs' preference
customers report serving, and (3) the incomes in these areas and the
extent to which they are urban or rural.
ESTIMATING PREFERENCE
CUSTOMERS' POTENTIAL RATE
CHANGES
------------------------------------------------------- Appendix III:1
To estimate how much preference customers' rates may change if the
customers paid market rates for the power they currently purchase
from the PMA, we calculated the average rates that each PMA
preference customer\1 paid for wholesale power from (1) all sources,
including the PMAs, and (2) sources other than the PMA, including the
wholesale market, in 1995.\2 Then, we took the difference between
these two rates, considering the latter to be the market rate.
Estimating the potential changes required several steps and
assumptions. First, to calculate how much preference customers paid
for the PMAs' power, we obtained data from Southeastern's,\3
Southwestern's, and Western's fiscal year 1995 annual reports. Then,
to learn how much each preference customer paid for the power it
purchased from other sources, we used the "sales for resale"
databases compiled by the Energy Information Administration (EIA).\4
We found that for about one-third of the three PMAs' preference
customers, EIA's data lacked the volumes of wholesale power the
customers purchased from non-PMA sources, the amounts the customers
paid for power, or both.\5
In these cases, we assumed the customer paid a rate equal to the
average market rate paid by customers of the same type (for example,
municipal utilities and cooperatives) for wholesale power in the
customer's state. We then combined each preference customer's
purchases of PMA power and non-PMA power to estimate how much the
customer paid for wholesale power from all sources in 1995.
Second, to estimate how each preference customer's rates would change
if it paid market rates for PMA power, we assumed that the customer
would pay a rate equal to the average rate it paid for wholesale
power from sources other than the PMA(s) in 1995. We used this
assumption because it is likely that in the period immediately after
a divestiture, the new owners of the PMAs' assets would charge the
prevailing market rates for wholesale power in the area.\6 We also
took this approach because we were unable to obtain forecasts of
future wholesale rates. Although EIA used its National Energy
Modeling System to forecast future electricity rates,\7 according to
agency officials, its projections are only for retail rates.\8
Others' projections of future wholesale rates are proprietary.
Finally, we compared the average rate each preference customer paid
for all its power in 1995 with the rate the customer paid for the
power it purchased from sources other than the PMA. The difference
in these two rates represents our estimates in cents per kWh of each
customer's potential increase in average rates if it paid market
rates for the power it currently purchases from the PMA.\9
After estimating how much preference customers' rates may change, we
analyzed the rate changes by state. To do this, we had to determine
the state in which each preference customer primarily sells power.
We obtained state designations for each preference customer from
EIA's Form 861 database of utilities for 1995. However, in cases
where the preference customer did not sell retail power, EIA did not
provide a state designation. In these instances, we consulted EIA's
PURCH and SALES databases of wholesale electricity transactions in
1995 and assigned the preference customer to the state where it sold
most of its wholesale power.\10 In the few cases where the preference
customer did not sell a large majority of its power to a single
state, we assigned the preference customer to the state where it is
listed in the Electrical World: Directory of Electric Power
Producers (1997 ed.).\11
Because we assumed that, after a divestiture, each customer would pay
a rate for power that equals what the preference customer paid for
non-PMA power in 1995, our methodology is conservative. If prices
for wholesale power decline in the future, as many industry analysts
and DOE officials believe they will, customers' rate increases would
be smaller than our estimates.
It is important to note that we estimated potential rate increases
for the preference customers that the PMAs listed in their 1995
annual reports. These customers buy power directly from the PMA. We
did not include utilities that indirectly buy PMA power through
direct preference customers such as generation and transmission
cooperatives and municipal joint action agencies. We did not include
these indirect customers because, with very few exceptions, the PMAs
did not count them as customers in their 1995 annual reports.
--------------------
\1 For our analysis, we considered preference customers who are
included in the Energy Information Administration's Form 861 database
of electric utilities. As a result, we did not include retail
customers that are owned by state or federal governments, such as
hospitals or military installations.
\2 As agreed with your offices, we used 1995 data to conform with
analyses we performed in preparation of a previous report,
GAO/RCED-98-43.
\3 We did not include TVA in our rate analysis because we believe it
is different from other preference customers in ways that made our
method of estimating rate changes inapplicable, for two reasons.
First, our methodology calculated the average rate each preference
customer paid in 1995 for its purchases of power from all sources.
However, unlike other preference customers, TVA generated over 97
percent of the power that it sold. Because TVA purchases so little
of the power it sells, we did not believe that it was appropriate to
apply this approach. Second, in our analysis, we used the Energy
Information Administration's data to determine the state in which
each preference customer primarily sells retail power. Each
preference customer and its total sales were assigned to one state.
The Energy Information Administration's state designation for TVA was
Alabama. However, since TVA sells large quantities of power to
distributors in seven states, we did not believe that it was
appropriate to assign the entire 1.9 billion kWh that Southeastern
sold to TVA in 1995 to Alabama. Also, TVA did not report the
counties and towns in its service territory in Electrical World:
Directory of Electric Power Producers. We, therefore, did not
include TVA's service territory in our state maps. (A less detailed
map of TVA's territory is included in app. I.) We also could not
analyze the income and urban/rural characteristics associated with
the area served by TVA.
\4 Specifically, we used EIA's PURCH.Y95 and SALES.Y95 databases,
which contain utilities' purchases and sales of wholesale power to
other utilities.
\5 EIA officials stated that the data were missing for several
reasons, including that the PMAs' customers were so small that they
did not have to file the reports EIA uses to compile the "sales for
resale" data (the Federal Energy Regulatory Commission's Form 1 and
EIA's Form EIA-412).
\6 In commenting on our draft report, DOE stated that market rates
would not necessarily be charged if a PMA is divested to a public
entity.
\7 See Electricity Prices in a Competitive Environment (DOE/EIA-0614,
Aug. 1997).
\8 We attempted to derive forecasts of wholesale prices from EIA's
retail price forecasts by subtracting distribution costs from EIA's
projections. We found, however, that our results were much higher
than the national average rates for wholesale power that EIA reports
in Financial Statistics of Major U.S. Investor-Owned Utilities.
After consulting with EIA officials, we chose not to use EIA's retail
price forecasts because they are based on the agency's judgmental
assignment of electricity generators' costs to services, such as
generation, transmission, and distribution, rather than actual sales
data.
\9 We do not report our estimates as percentages: Since many
preference customers paid relatively low base rates for power in 1995
(e.g., between 1 and 2 cents per kWh), smaller increases measured in
cents would result in seemingly large percentage increases. For
example, if a preference customer in 1995 paid an average of 1.5
cents per kWh for power, a relatively small increase of 0.5 cent per
kWh would produce a seemingly large increase of 33 percent. In
addition, if we expressed the rate increases as percentages, the same
increase measured in cents per kWh would be reported as different
increases for two customers with different base rates. For these
reasons, we believe that reporting rate changes in cents per kWh
better portrays the true impact of the change.
\10 According to EIA, as of November 1998, these data had not been
released for 1996.
\11 Electrical World: Directory of Electric Power Producers is a
standard reference for data on the electricity industry. It compiles
specific data on subjects such as individual utilities' power
production capacities, power sales, sources of purchased power,
distribution facilities, as well as the service areas, which are
provided by the utilities themselves.
ESTIMATING CHANGES IN
RESIDENTIAL CUSTOMERS'
ELECTRICITY BILLS
------------------------------------------------------- Appendix III:2
To estimate how each preference customer's rate change would affect
the rates paid by its residential end-users, we assumed that (1) the
preference customer would pass the rate change on proportionally to
its end-users and (2) that each state's residential end-users would
consume a quantity of electricity equal to the average residential
consumption for that state in 1995, according to EIA. The monthly
increase in a residential end-user's electricity bill equals the
preference customer's rate increase after the PMA begins charging
market rates (in cents per kWh) times the residential end-user's
average annual electricity consumption for the appropriate state (in
kWh), divided by 12.
DEFINING PREFERENCE CUSTOMERS'
SERVICE AREAS
------------------------------------------------------- Appendix III:3
To define the preference customers' service areas, we identified the
counties and/or towns in Electrical World: Directory of Electric
Power Producers (1997 ed.) that each of the customers in our analysis
reported serving. As was true with our rate analysis, we included
only the preference customers that purchased power directly from the
PMAs--that is, those customers the PMAs listed in their 1995 annual
reports. If we had included utilities that indirectly purchase PMA
power (through direct preference customers), such as generation and
transmission cooperatives and municipal joint action agencies, more
counties and towns would be shown on our state service territory
maps. According to DOE officials, many additional counties would be
shaded in, among other states, Montana, South Carolina, and Wyoming.
CHARACTERIZING INCOMES AND
URBAN AND RURAL POPULATIONS IN
PREFERENCE CUSTOMERS' SERVICE
AREAS
------------------------------------------------------- Appendix III:4
To examine the incomes in areas that ultimately consume PMA power, we
obtained 1990 census data (based on calendar year 1989) from the
Census Bureau on household incomes in each county and town the
preference customers reported serving in Electrical World.
To determine the degree to which preference customers' service areas
were urban or rural, we obtained 1990 census data from the Census
Bureau on the urban and rural populations in each county and town the
preference customer reported serving. We classified a county or town
as urban or rural if at least 80 percent of its population is urban
or rural as defined by the Census Bureau.\12 If the county's or
town's population is less than 80 percent urban or rural, we
classified it as "mixed."
Because the PMAs historically are believed to have served areas that
had lower median incomes and were less urbanized, our use of census
data from 1990 yields conservative results, as income and urban
populations generally increase over time.
We conducted our review from May through November 1998 in accordance
with generally accepted government auditing standards.
We provided a draft of this report to DOE's Power Marketing Liaison
Office, which represents the views of Southeastern, Southwestern, and
Western. Its comments and our responses are included in appendix V.
We also met with representatives of the American Public Power
Association, the Edison Electric Institute, and the National Rural
Electric Cooperative Association--national organizations representing
groups concerned with the pricing of power provided by the PMAs,
among other things--to discuss our methodology and the results of our
review.
--------------------
\12 The Census Bureau generally considers a place to be urban if its
population is 2,500 or more.
STATE-SPECIFIC DATA ON POTENTIAL
RATE IMPACTS AND SERVICE AREA
DEMOGRAPHICS
========================================================== Appendix IV
This appendix provides, for each state that receives PMA power from
Southeastern, Southwestern, and/or Western, (1) the counties and
towns that the preference customers included in our analysis report
serving and a map showing these areas and (2) the estimated rate
changes if market rates are charged, by number and percentage of
preference customers; household incomes in areas potentially
receiving power; the extent to which these areas are urban or rural;
and the extent to which the individual state's total power
consumption is provided by the PMA(s) through the preference
customers included in our analysis.
To define the preference customers' service areas, we identified the
counties and/or towns in Electrical World: Directory of Electric
Power Producers (1997 ed.) that each of the customers considered in
our analysis reported serving. As was true with our rate analysis,
we included only the preference customers that purchased power
directly from the PMAs--that is, those customers that the PMAs listed
in their 1995 annual reports. If we had included utilities that
indirectly buy PMA power (through direct preference customers), such
as generation and transmission cooperatives and municipal joint
action agencies, more counties and towns would be shown on our state
service territory maps. According to DOE officials, many additional
counties would be shaded in, among other states, Montana, South
Carolina, and Wyoming.

COMMENTS OF THE DEPARTMENT OF
ENERGY'S POWER MARKETING LIAISON
OFFICE
========================================================== Appendix IV
(See figure in printed edition.)
(See figure in printed edition.)
(See figure in printed edition.)
(See figure in printed edition.)
The following are GAO's comments on the Power Marketing Liaison
Office's letter dated October 30, 1998.
GAO'S COMMENTS
-------------------------------------------------------- Appendix IV:1
1. DOE comments that our data sources are flawed because we relied
on incomplete and/or inaccurate data and that it is impossible to
have confidence in conclusions drawn from the data's analysis. To
address each of our objectives, our analyses used data reported by
the PMAs and their preference customers--data that we believe to be
the best available. DOE recognizes that obtaining complete data on
the electric utility industry is not easy. We believe that we used
the data appropriately to satisfy the objectives of our review and
that our methodology is sound. However, we agree the data we used
have some limitations and we have noted the limitations in our
report. Many of the concerns that DOE expresses do not deal with the
data we used but with the definition of a preference customer of a
PMA. For our analysis, we included only the preference customers who
purchased power directly from the PMAs--as listed in the PMAs' 1995
annual reports. We did not include utilities that indirectly
purchase PMA power because the 1995 annual reports of two of the
three PMAs do not include them in their customer lists.
Southwestern's 1995 annual report states that two of its customers
also serve a number of municipal utilities and includes these
municipal utilities in the total number of customers. The annual
reports of Southeastern and Western, however, list only the customers
that buy power directly from those PMAs and do not include the
municipal utilities that purchase power from generation and
transmission cooperatives or municipal joint action agencies.
Because Southeastern and Western together represent over 90 percent
of the total preference customers of the three PMAs included in our
analysis, we used their approach. However, to address DOE's
concerns, we added statements to the report in several places
explaining that our analysis did not include utilities that
indirectly purchase PMA power.
For our analysis of urban/rural populations, we used the counties and
towns that the preference customers included in our rate analysis
reported to Electrical World: Directory of Electric Power Producers.
In connection with identifying the areas that preference customers
report serving, we acknowledge that the data in Electrical World may
not match the actual service territories because utilities report to
Electrical World the counties and/or towns they serve without
specifying the exact service boundaries within these counties and
towns. However, we used these data because they (1) were reported by
the preference customers and (2) were the best available. We believe
this approach adequately addresses our objective of identifying the
areas that the three PMAs' preference customers report serving and
does not affect our primary objective, to estimate potential rate
impacts by state.
2. DOE states that we omitted from our analysis generation and
transmission cooperatives and municipal joint action agencies that
purchase power from the PMAs. We did not exclude them. We estimated
a potential rate change for every generation and transmission
cooperative and municipal joint action agency that purchased
wholesale power from Southeastern, Southwestern, and Western in 1995.
We also attempted to include them in our maps and urban/rural
analysis. However, in many cases, the generation and transmission
cooperatives and municipal joint action agencies sell only wholesale
power to other utilities and do not provide retail service and, thus,
do not report serving any counties or towns. As a result, we were
unable to reflect such service territories on our maps. Similarly,
since our urban/rural analysis relied on the Census Bureau's data of
populations in the counties and towns that the preference customers
report serving, we did not include in our analysis the service
territories of the utilities that purchase power from the generation
and transmission cooperatives and municipal joint action agencies.
As we noted in comment 1, we did not include the generation and
transmission cooperatives or municipal joint action agencies in our
analysis because the PMAs' annual reports, with very few exceptions,
do not include them either.\13 However, it is important to note that
if our rate analysis had included the municipal utilities that buy
from preference customer generation and transmission cooperatives and
municipal joint action agencies, we believe that the rate increases
for many of these utilities would have been very small: If a
municipal utility purchased all its power from a direct preference
customer of the PMA, the municipal utility's rate increase would
equal the increase we estimated for the direct preference customer.
If the utility purchased a portion of its power from sources other
than the preference customer, its rate increase would be lower. For
example, according to Southwestern's fiscal year 1995 annual report,
Kansas Municipal Energy Agency (Kansas MEA) purchased power from
Southwestern and transmitted it to 24 municipal utilities. We
estimate that if the Kansas MEA paid market rates for the power it
purchased from the PMA, its average rate would rise by 0.22 cent per
kWh, a relatively small increase. If a municipal utility purchased
all its power from the Kansas MEA, its rate would also rise by 0.22
cents per kWh. If a municipal utility purchased half of its power
from the Kansas MEA, its rate increase would be 0.11 cents per kWh.
Municipal utilities' increases would often be small because the
direct preference customers who sell them power often purchase a
small percentage of their total power from the PMA.
3. DOE states that our maps do not show the service areas of the
customers of the generation and transmission cooperatives and
municipal joint action agencies. We agree. However, to be
consistent with our rate analysis, we included only the counties and
towns that the preference customers (those that purchase power
directly from the PMAs) report. If we had included the service
territories of the utilities that purchase power from preference
customers as DOE suggests, our state maps would have had more
shadings for counties and/or dots for towns. However, it is
important to note that, in many cases, the additional counties and
towns in our maps would receive relatively small portions of their
power from the PMA. For example, Southwestern's 1995 annual report
states that the PMA sells power to the Louisiana Energy and Power
Authority, which, in turn, serves nine municipal utilities. We
estimate that Louisiana Electric and Power, purchased 8.15 percent of
its power from the PMA in 1995. This means that the nine municipal
utilities received, at most, 8.15 percent of their power from
Southwestern. If the municipal utilities purchased portions of their
power from other sources, the counties and towns they serve would
consume a smaller portion of PMA power. Our analysis shows that many
of the preference customers that sell power to other utilities
purchase less than 10 percent of their power from the PMA. Moreover,
regardless of how many utilities buy PMA power indirectly through
preference customers, the portion of a state's electricity
consumption that comes from the PMA remains the same--for example,
0.7 percent in Louisiana.
4. In its comments, DOE states that our analysis shows that
Southwestern is serving 14 towns and one county in the State of
Missouri, with 93 percent of PMA power going to urban areas of the
state. We believe that DOE misinterpreted our analysis. Our
analysis does not show that 93 percent of Southwestern's power in
Missouri goes to urban areas. Our analysis does show that of the 14
towns that preference customers who buy directly from the PMA report
serving, 13, or 93 percent, have populations that are at least 80
percent urban, as defined by the Census Bureau. DOE states that
Associated Electric Cooperative has a "PMA power allocation [that]
serves rural areas throughout the State of Missouri." However, this
power is distributed to these areas by the utilities that purchase
power from Associated Electric, not Associated Electric itself.
Associated Electric did not report serving any counties or towns to
Electrical World, the source of our data. Moreover, Southwestern, in
its 1995 annual report, does not include the utilities that purchase
power from the Associated Electric Cooperative in its total count of
customers. Therefore, neither did we.
5. DOE states that using 1995 data compromises our rate analysis
because (1) PMAs' rates have recently declined and (2) prices for
power purchased during periods of peak use have recently increased.
These two factors would increase potential rate increases, but only
if market rates remain the same. However, according to officials of
the Edison Electric Institute, market rates for wholesale power have
also declined since 1995. As the market continues to evolve, many
industry experts believe these rates will fall farther. If market
rates fall more than the PMAs' rates, our estimates of rate increases
will prove to be overstated. We have seen no evidence that the PMAs'
rates have fallen more than rates in the wholesale market.
6. DOE maintains that power from the Pick-Sloan project will be
reallocated to 25 Native American tribes and 11 other new customers
in the Upper Midwest in 2001 and that, as a result, our analysis will
be "even further outdated." However, we were asked to examine the
three PMAs' sales, based on the most recent data--1995, not their
sales in the future. In addition, although Western may be
reallocating its power, this does not necessarily mean that the new
allocation would appreciably change the profile of the service areas
(in terms of the extent to which they are urban or rural and in terms
of their household income). This profile would change only if the
areas losing Western's power are more urban or rural or different in
income than the areas that would gain access to Western's power.
Moreover, although Pick-Sloan sold more power than other of Western's
projects, it nonetheless represented about only about one-third of
Western's total sales in 1995. Consequently, the reallocation would
have to be very large to significantly change the overall profile of
Western's preference customers' service territories.
7. DOE states that average rates are not a good proxy for specific
power services from PMAs. We acknowledge that average revenue per
kWh (total revenues/total electricity sales) is an imperfect
indicator of electricity rates because it combines the costs of
several types of services, such as capacity, peak service, and
off-peak service. However, as we have stated in several past
reports, we believe it is a strong, broad indicator of the relative
power production costs of the PMAs compared to those of
investor-owned utilities and publicly owned generators. We agree
that preference customers would likely pay higher than the average
rate per kWh in replacing the portion of PMA power that is used
during periods of peak demand.
8. DOE states that in many parts of the Upper Midwest and Southeast,
it is typical for towns in a county to be served by an investor-owned
utility while the remaining parts of the county are served by a rural
electric cooperative. Thus, DOE believes that our analysis is flawed
if the data do not account for this difference. We agree this may be
an issue. However, as stated previously, we relied on the set of
counties and towns that the preference customers reported serving to
Electrical World. The preference customers did not specify which
portions of a county they served when they reported serving a county.
Also, in Midwestern states, such as Iowa, Missouri, and Nebraska,
preference customers primarily reported their service areas as towns
rather than counties. Thus, the problem concerning counties that DOE
identified would not arise there. In addition, even if, within a
particular county, an investor-owned utility serves a town, it may
not follow that the area outside the town has lower household
incomes.
9. DOE states that we omitted state/federal agencies. We excluded
state and federal agencies because, with a few exceptions, they are
not utilities and thus are not in EIA's Form 861 or "sales for
resale" databases. As a result, we could not perform calculations on
potential rate impacts with the approach we used for preference
customers who are utilities. We excluded state and federal agencies
from other analyses because (1) they do not provide retail service to
residential end-users and (2) we wanted to keep the group of
customers consistent across the analyses. In addition, DOE provides
no economic analysis that the PMAs' sales to these agencies provide a
"large benefit to the state they are located in." In most cases, even
if the sales to these agencies were included in the analysis, the
PMAs' portion of a state's total electricity consumption would be
relatively small. We agree that some indirect economic impact may be
attributable to the lower price of the power--relative to other
retail prices--consumed by the preference customers not included in
our analysis, but its measurement is uncertain.
10. DOE states that TVA is omitted. We agree that if we had been
able to include the 160 distributors that received TVA power in 1995
in our analysis, the percentages of PMA power provided to the seven
states served by TVA would have increased. However, because of data
limitations, such as EIA's designating TVA as an Alabama utility in
its Form 861 database and TVA's not reporting a service territory in
Electrical World, we could not apply the methodology used in our
analysis and were unable to develop and implement a methodology to
appropriately incorporate TVA. However, our draft explained that
Southeastern sells power to TVA, provided information on the amount
of power that Southeastern sold to TVA in 1995 and 1996, and provided
a map of TVA's service territory. In addition, we have added a more
detailed explanation of our methodology concerning TVA in appendix
III.
11. DOE believes that Wisconsin should not be included in our
analysis because Wisconsin Public Power received only "nonfirm"
(interruptible during peak periods) power from Western. However,
Western listed Wisconsin Public Power as one of its customers for
1995, and we believe that it was appropriate to include this customer
in our rate analysis because we did not differentiate between firm
(always available) and nonfirm power sales. Also, because Wisconsin
Public Power sells only wholesale power and did not report serving
any counties or towns in Electrical World, we could not include it in
our other analyses.
12. DOE states that our report does not maintain a neutral
description of the findings because the report goes beyond data
reporting and does not present all opposing points of view. It cites
as an example our observation that in cases where potential rate
increase may be relatively large, PMAs currently sell power at
relatively low rates and rate caps could be used to mitigate these
increases. We believe that our report is balanced and that,
throughout our report, we present a neutral description of our
objectives and findings. We mention that PMAs' rates are relatively
low to provide context for the relatively large rate increases. It
is easier to understand the significance of a rate increase that
exceeds 1.5 cents per kWh if the reader understands the base rate
upon which the increase is calculated. On the issue of rate caps, we
did not intend for our discussion to be a recommendation. We
included it because, as in previous reports, this issue has been an
important consideration in other deregulatory initiatives.
13. DOE states that our classifications of rates are subjective. We
agree. However, we devised the parameters of these classifications
on the basis of our examination of all the rate changes in our
analysis. Moreover, we explicitly describe the values attached to
each of these classifications in our report. We used these
categories to simplify the discussion, not as a definitive statement.
14. With regard to selling power to high-income areas, DOE
misinterprets our analysis. In the examples cited, we refer to the
percentage of households with higher incomes, not the median income.
More generally, a county may have a median that is relatively close
to the statewide median, yet still have a large portion of households
with higher incomes. We agree with DOE's comment regarding Native
Americans' receiving PMA power and have added an example for balance.
15. With regard to our not reporting rate increases as percentages,
we made a subjective judgment not to do so. As we stated in appendix
III, we believe that reporting rate changes in cents per kWh more
accurately portrays the true value of the changes. In addition, the
base rates preference customers paid in 1995 differ greatly from
customer to customer. As a result, if we expressed the rate changes
as percentages, the same increase measured in cents per kWh would be
reported as different increases for two customers with different base
rates.
16. In response to DOE's assertion that our methodology is not
conservative, we disagree. We believe our methodology is
conservative because we assume no changes in wholesale market prices.
If wholesale prices decline in the future, as many industry experts
predict, our estimates of rate increases will prove to be overstated.
Because we could not incorporate forecasts of wholesale prices, we
believe our approach is conservative.
17. DOE states that our urban/rural terminology may be misleading.
As suggested, we have included the Census Bureau's definition of
urban in the body of our report and appendix III.
--------------------
\13 Southwestern's 1995 annual report includes 2 (of more than 60
customers reported), and Southeastern's and Western's, none.
