      Subject: Energv Consumution: Federal Agencies’ Electric&v Use and Cost

      Changes to the electricity industry are being considered at the federal and state
      levels that could affect federal agencies’costs for electricity. Currently,
      electricity constitutes about 45 percent of the energy used and about 80 percent
      of energy costs.’ To assist the Committee in its deliberations on changes in the
      electricity market, you asked us to provide information on (1) the amount of
      electricity used in federal buildings and facilities and (2) the costs of this
      electricity from fiscal year 1986 through fiscal year 1995. As agreed with your
      offices, we plan, in a subsequent review, to exarnine the estimated savings to
      the federal government If legislation were enacted authorizing the purchase of
      electricity competitively on the open market.




      %lectricity data are a subset of the energy data. Energy includes electricity
      and other fuels, such as natural gas, coal, and fuel oil.

                                                    GAO/fWED-97-97R Federal ElectriciQ   Use
    B-276408

    In summary, the federal government used about 61 billion kilowatt-hours’ of
    electricity in fiscal year 199~the latest year for which data were available-in
    its buildings and facilities. Electricity use in the federal government is highly
    concentrated in a few agencies: The Department of Defense (DOD) used about
    50 percent of the total in tical year 1995, and the five next largest consuming
    agencies-the Tennessee Valley Authority (TVA), the United States Postal
.   Service, the Department of Energy (DOE), the General Services Administration
    (GSA),3and the Department of Veterans Affairs-accounted for about another 34
    percent.

    Electricity costs in federal buildings and facilities in fiscal year 1995 totaled
    about $3.5 billion. Electricity costs were similarly concentrated, with DOD and
    the five other agencies accountig for about 87 percent of the total cost.

    BACKGROUND

    DOE’s Office of Federal Energy Management Programs (FEMP) coordinates
    federal energy efficiency efforts and reports annually to the Congress on federal
    energy consumption and conservation activities by executive branch agencies4
    FEMP gathers these data from agencies under three categories: buildings and




    2A watt is the basic unit used to measure electric power. A kilowatt is 1,000
    watts. A kilowatt-hour (kWh) is equal to 1 kilowatt of power applied for 1
    hour. The average household in the United States uses about 10,000 kWh of
    electricity per year, according to the Department of Energy’s Energy
    Information Administration.
    3GSA reports energy consumption data for buildings that it controls including
    data for buildings leased to tenant agencies to whom GSA has not delegated the
    responsibility for operation and maintenance.
    4For fiscal year 1995, FEMP’s data were for 28 executive branch agencies and
    did not include the judicial and legislative branch agencies. Enclosure I is a
    listing of the agencies that report data to FEMP.

facilities, energy-intensive operations,5 and vehicles and equipment6 In fiscal
year 1995, federal agencies used about 1.9 percent of the energy consumed in
the nation, according to FEMP.7 Because our primary focus for this report is
electricity use and costs, we combined the buildings and facilities and energy-
intensive operations categories for our discussion of federal buildings and
facilities.

The few agencies that have facilities outside the United States differ as to how
they report to FEMP electricity consumption at such facilities. F’EMP officials
said that they do not attempt to isolate these data A DOD official told us
DOD’s total use reported to FEMP includes nondomestic use-about 24 percent
of DOD’s preliminary total use for &xl year 1996, costing about $420 million.
Electricity use at facilities outside the United States would not be affected by
restructuring the electricity industry in the United States.

ELECTRICI’I’Y USE IN FEDERAL BUILDINGS AND FACILITIES

Over the N-year period fiscal years 1986-95, the use of electricity measured at
federal buildings and facilities increased from 0.16 quadrillion British thermal
units (Bt@ in fiscal year 1986 to 0.21 quadrillion Btu in fiscal year 1995.
Fi,sure 1 shows electricity’s portion of energy use in quadrillions of Btu for the
28 agencies reportink to FEMP.



!?bis category includes the energy consumed in industrial operations, certain
research and development activities, and in electronic-intensive facilities, such
as air tmf6c control towers.

‘For &xl year 1995,28 agencies reported that buildings and facilities used
about 32 percent of the energy at a cost of about $3.6 billion, energy-intensive
facilities used about 9 percent at a cost of about $0.9 billion, and vehicles and
equipment used the remaining 59 percent at a cost of about $3.4 billion.
7Annual Renort to Congress on Federal Government Energv Management and
Conservation Programs. Fiscal Year 1995, DOE, Washington, DC.: Draft.
According to FEMP officials, the draft, which is expected to be published in
April 1997, contains tial consumption totals for fiscal year 1995, which we
used.
*A Btu, the quantity of heat required to raise the temperature of 1 pound of
water 1 degree Fahrenheit, is a standard unit for measuring the energy used in
operating buildings and facilities.

Notes: The increases in fiscal years 1994 and 1995 are largely attributable to TVA.
They result from a revised management accounting method at TVA, designed to reflect
requirementsof the Energy Policy Act of 1992, which captures the costs of electricity
use in its plants (most of which is electricity used for the generation of electricity).
According to FEMP and TVA officials, comparable data are not available for previous
years. FEMP and TVA officials agree that this methodology provides additional
management information, but to be consistent with other agencies that produce
electricity, the fiscal year 1996 FEMP report will likely not reflect this energy use.

Energy includes electricity and other fuels, such as natural gas, coal, and fuel oil.

Officials at DOE’s Energy Information Administration, DOD, and FEMF’were
unable to provide independent estimates of federal agencies’future electricity
consumption. Whether the agencies’future rate of growth in electricity
consumption ‘can be extrapolated from the historic patterns is very uncertain.
However, if one assumes that the growth rate for the near future would
generally follow the trend of the recent past&the rate could range from an
increase of 1 percent annually to a decrease of 1.6 percent. We calculated this
range using electricity consumption by federal agencies, as reported to F’EMP
for the last 11 years. We estimated the growth rate for three recent time
periods-the last IO years, 5 years, and 3 years-which resulted in average annual
growth rates of positive 1 percent, and negative 1 and 1.6 percent, respectively.

ELECTF?ICITY COSTS IN FEDERAL BUILDINGS AND FACILITIES

According to TVA’s Internal Energy Management Program Coordinator, because of the
nature of TVA’s business, TVA’s cost is based on a benchmark rate and does not
reflect. the actual cost for electricity used in station service.

 AGENCY COMMENTS

 We provided copies of a draft of this report to DOE and DOD, the largest single
 federal electricity consumer, for review and comment. We met with officials of
 DOE, including the Deputy Director, FEMP, who fully concurred with the
 information presented in the draft report. FEMP also provided some clarifying
 comments that have been incorporated in the report as appropriate. For
 example, FEMP noted that we should more fully explain the extent to which
 agencies differ in reporting nondomestic electricity use. We revised our
 discussion to address these concerns. In addition, DOD fully concurred with
 the facts contained in the draft.

We conducted our review primarily at DOE’s FZMP in Washington, DC. We
interviewed officials and obtained data on electricity and energy use and costs
at F’EMP and its contractor, which performs data analysis and provides
information for FEMP’s reports. The electricity data are a subset of the energy
data that F’EMP includes in DOE’s annual report to the Congress. We
contacted officials at the Department of State, DOD, GSA, the National
Aeronautics and Space Administration, and the Panama Canal Commission to
identify how much of those agencies’reported electricity use was in the United
States- We contacted officials at the Department of State, DOD, DOE, GSA, and
TVA to discuss consumption reporting concerning energy-intensive facilities.
We discussed projected electricity use fiorn 1995 through 2000 with officials of
DOE’s Energy Information Administration. We contacted officials of the
Architect of the Capital, our own office, and the Government Printing Office to
 obtain electricity consumption data for the judicial and legislative branches.‘*

We did not verify the data obtained from FEMP, but we did discuss FEMP’s
procedures for validating the data submitted by the agencies. A ITEMP official
told us that the office idenufies significant variances, defied as 2 to 5 percent
depending on the type of information, from prior reports and asks agencies to
either explain those variances and/or provide narratives for inclusion in F’EMP’s
annual report. FEMP provides, with its annual reporting guidance, an
electronic worksheet to allow agencies to self-check their consumption and
cost data.



We conducted our work from January 1997 to March 21, 1997, in accordance
with generally accepted government auditig standards. As arranged with your
offices, unless you publicly announce its contents earlier, we plan no further
distribution of this report until 30 days after the date of this letter. At that
time, we w-ill send a copy to the Secretary of Defense and the Secretary of
Energy. We wiU also make copies available to others upon request. If you or




 ‘“According to data provided by legislative branch officials, the legislative and
judicial branches’use is less than 1 percent of the government’s electricity use.
