# Preface

The Electric Power Annual 2001 presents a summary

of electric power industry statistics at the national

level. The objective of the publication is to provide

industry decisionmakers, government policymakers,

analysts, and the general public with historical data

that may be used in understanding U.S. elec tricity

markets. The Electric Power Annual, is prepared by

the Electric Power Division; Office of Coal, Nuclear,

Electric and Alternate Fuels; Energy Information

Administration (EIA); U.S. Department of Energy.

In the private sector, the majority of the users of the

Electric Power Annual, are researchers, analysts, and

individuals with policymaking and decision

- making

responsibilities in electric utility companies or other

energy concerns. Other users include financial and

investment institutions, econom ic development

organizations, special interest groups, lobbyists,

electric power associations, and the news media.

In the public sector, users include the U.S. Congress,

Federal government agencies, State governments and

# Electric Power Industry 2001: Year in Review

Introduction

The pace of restructuring the electric power industry

slowed significantly in 2001. Market volatility and

associated price increases in California during the

2000

- 2001 period caused serious financial problems

for the investor

- owned electric utilities in t he State.

The financial turmoil was capped by the bankruptcy

filing of Pacific Gas and Electric Company and the

near bankruptcy of Southern California Edison

Company.

As the creditworthiness of the investor owned electric

utilities deteriorated, the Stat e of California stepped in

to buy power at high prices. This intervention created

financial problems for the State and imposed burdens

that are likely to last for a number of years in the

future. In addition, electricity customers in the State

will be re quired to pay rates that are significantly

higher than those prevailing in the prior periods. As a

result of the California situation, other States in the Northwest also experienced varying degrees of

economic impacts as power prices increased regionally.

The bankruptcy of Enron Corporation in the midst of

allegations of financial improprieties contributed to

charges that the power markets could be manipulated

and that the regulatory authorities lacked the tools to

monitor such abuses in a timely fashion . Overall, the

above events have, at least temporarily, led to an

erosion of confidence in the efficacy of competitive

power markets. As a result, nearly half the States have

adopted a go

-

slow approach. Others like New Mexico

and Oklahoma have delayed i mplementation.

California, which spearheaded the movement toward

deregulation, has stepped back. By the end of 2001,

restructuring had either been delayed or suspended in 8

States that previously enacted legislation or issued

regulatory orders for its im plementation (Figure 1).

Eighteen other States that had ongoing investigations

either at the legislative or regulatory levels in the year

2000 reported no such activity in 2001.



# Figure 1: Status of State Electric Utility

Deregulation Activity, as of January 2002

1 These States have either enacted enabling leg islation or issued a regulatory order to implement retail access. Retail access is either currently available to all or some

customers or will soon be available. Some States are currently running pilot programs, and they will begin to implement retail acce ss in the near future: Arizona,

Connecticut, Delaware, District of Columbia, Illinois, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania,

Rhode Island, Texas, and Virginia.

2 These States have either passed l egislation or issued regulatory orders to delay implementing retail access: Arkansas, Montana, Nevada, New Mexico, Oklahoma, and

Oregon. Although West Virginia passed legislation that approved the PSC's plan to restructure and implement retail access, the process is delayed until a bill for tax

reform is enacted.

3 The CPUC ordered suspension of direct retail access.

4 These States have not enacted enabling legislation to restructure the electric power industry or implement retail access: Alabama, Alaska, C olorado, Florida, Georgia,

Hawaii, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Minnesota, Mississippi, Missouri, Nebraska, North Carolina, North Dakota, South Carolina, South

Dakota, Tennessee, Utah, Vermont, Washington, Wisconsin, and Wyoming.

## As a result of the financial turmoil in the power sector,

commitments and planning for new plants began to

slow in 2001. Infrastructure investments including

additions to transmission capability have not kept pace

w ith increases in demand for power and trading

requirements. These developments retard the growth

of a fully competitive market for power.

The electric power industry is and will continue to be

in a state of flux in the foreseeable future. FERC’s

efforts to create a competitive market for power

nationally will hinge on the critical support it receives

from the States. Changes will continue to emerge

albeit at a slower pace.

The following is a summary of statistics gathered on

the U.S. electric power ind ustry for 2001.



# Industry Profile

The electric power industry in the United States is

composed of traditional electric utilities, and

nontraditional participants, including energy service

providers, power marketers, and independent power

producers (IPP). Electric utilities include investor

owned electric utilities, municipal and State utilities,

Federal electric utilities, and rural electric cooperatives.

A utility is defined as a corporation, person, agency,

authority, or other legal entity or instrumen tality

aligned with distribution facilities for delivery of

electric energy for use primarily by the public. In total,

there are more than 3,100 electric utilities in the United

States (Figure 2).

EIA

- 861, “Annual Electric Power Industry Report."

Historically, the most influential of these entities have

been the vertically integrated investor

- owned utility

companies that provided generation, transmission,

distribution, and ret ail energy services for all customers

in a designated service territory. However, the industry has continued to change from this vertically integrated

structure to a functionally unbundled industry with a

competitive market for power generation. As a resu lt,

there were 128 active power marketers operating by the

end of 2001.

Electric power that is sold to end users may be

generated by electricity generators that are traditional

electric utilities, by independent power producers, or

by combined heat and power producers. An

independent power producer is an entity defined as a

corporation, person, agency, authority, or other legal

entity or instru mentality that owns or operates facilities

for the generation of electricity for use primarily by the

public, and is not an electric utility. Combined heat

and power producers (typically industrial cogenerators)

are plants designed to produce both heat and electricity

from a single heat source. There are approximately

2,800 unregulated independent power producer s or

combined heat and power plants in the United States.



# Generation

In 2001, the total U.S. net generation of electricity was

3,734 billion kilowatthours, 2

- percent lower than 2000.

This decrease is unusual in that net U.S. generation has

historically increased from year to year. This is only

the second time in over 50 years that there has been a

decrease in net generation (Figure 3). Demand

reductions caused by an economic slowdown explain

somewhat corresponding declines in generation.

Because nuc lear and coal units are typically operated

as base load generators (the generating equipment

normally operated to serve loads on an around

- the

clock basis), they contribute a major share of electric

generation. In 2001, coal plants accounted for 51

percen t of generation and nuclear plants for 21 percent

of generation for a total of 72 percent of power supply,

although coal and nuclear plants provide just under 50

percent of total capacity.

In contrast, natural gas and petroleum units typically

run in cycl

ing (load

- following) service or as peaking

capacity for short periods of time to meet the highest

daily loads. Consequently, natural gas and petroleum

plants account for only 20 percent of generation,

although they make up 38 percent of total capacity.

W hile net generation dropped for the industry overall,

the independent power producers’ share of net

generation was up sharply in 2001. This is a result of

both new plant construction by independent producers

and plant divestitures by investor owned utilit ies. In

contrast to IPP electric

– only production, net generation

## Energy Information Admini stration/Electric Power Annual 2001 3 

## by combined heat and power producers has remained

fairly constant from 1996 through 2001 at 8 to 9

percent of the total net generation.

# Capacity

In 2001, total net summer generating capacity was 848

gigawatts, up 4.5 percent from the year 2000. Large

increases in natural

gas capacity, which increased by

31 percent to 126 gigawatts, drove most of this

increase in capacity.

The total amount of U.S. net summer capacity for 2001

of coal

- fired capacity is more than two times higher

than the capacity for any other single ener gy source

(Figure 4). However, most “dual fuel” generating

plants consume natural gas most of the time and use oil

as a back

- up source. When the aggregate capacity of

these dual fuel plants is added to the natural gas

- only

capacity, the total for natural gas has a 33

- percent share

of the total U.S. net summer capacity for 2001. The

2001 net summer capacity for “other renewables” fuel

sources is dominated by biomass and municipal solid

waste generating plants. Contributions by these

sources increased 4 p ercent over the year 2000,

resulting in an additional 608 MW of net summer

capacity from this fuel source.

The aggregate ann

ual capacity factor is an index that

shows the average production by a group of generating

facilities as a percent of the maximum possible

production over the year 2001. At year

- end 2001,

nuclear plant capacity factors were at 89.4 percent

(Figure 5) and coal plant capacity factors were at 73.4

percent, consistent with base load operation. In

contrast, gas and oil units had, respectively, capacity

factors of only 34.4 percent and 27.1 percent, reflecting

load

- following and peaking operations. Hydroelectr ic

generators had an average capacity factor of only 17.2

percent.

between Available Resources and Net Internal

Demand, expressed as a percent of Available Note: Net Summer capacity of 0.2 percent from blast furnace gas, propane gas, and other manufactured

and waste gases derived from fossil fuels is not included.

## Energy Information Admini stration/Electric Power Annual 2001 4 

## Resources. This is the capacity available to cover

random factors such as forecast outages of generating

equipment, demand forecast er rors, weather extremes,

and capacity service schedule slippage. Variations

from capacity margins in regional tables may exist due

to differences in reporting methods for purchases and

sales. Summer capacity margins in the contiguous

United States decline d over the past 12 years by over 7

percent. Despite a brief increase in 1999 and 2000, the

downward trend has reemerged with nationwide

capacity margins at 14.5 percent in 2001 (Figure 6).

Although net internal demand has increased an average

of 2 percen t per year over the period from 1999 to

2001, capacity resources have only increased

approximately 1 percent a year in the corresponding

time period.

According to the North American Reliability Council

(NERC), a reduction in capacity margins in 2001 is

primarily due to variances in qualitative assumptions

incorporated in the estimation process for that year. As

an ex ample, drought

- induced restrictions on

hydroelectric generating capacity in the Northwest and

South played a critical role. Other influencing factors

for the 2001 estimates include the then prevailing

concerns with respect to the availability and adequacy

of natural gas supplies and the higher

- than

- usual

outages in the West and South. Attempts to secure

suitable interconnection and transmission access

agreements were frustrated in varying degrees by siting

and permitting hurdles, difficulties in financing due to

market uncertainties, and fuel supply adequacy issues. 

# Fuel

Consumption of coal for electricity generation was

down 2.2 percent from 2000, going from 995 to 973

million short tons in 2001. Use of petroleum for

electricity generation increased 13.9 percent, going

from 195 million barrels in 2000 to 222 million barrels

in 2001. Consumption of natural and other gases used

for electricity generation increased only 0.7 percent to

6 trillion cubic feet in 2001.

In 2001, the average cost of natur al gas to electric

utilities increased 4.3 percent and the average cost of

coal increased 2.6 percent. However, these average

prices do not reflect the extraordinary volatility in the

spot markets for natural gas and coal in 2001. For

example, the spot p

rice for natural gas at the Henry

Hub trading point exceeded 9.00 per million Btu in

January 2001, but was under 3.00 per million Btu by

Fall. Coal spot prices were also very high at the

beginning of 2001 and moderated as the year

progressed. The high pr ice of spot market natural gas

for much of the year may be one factor explaining why

natural gas generation increased only slightly even as

many new natural gas

- fired plants entered commercial

operation.

The total consumption of these fuels and others

res ulted in the production of 3,734 billion

kilowatthours (Figure 7). Approximately 1,900 billion

kilowatthours, over half of the total net generation, was

produced by coal

- fired generators. Nuclear and gas

fired generation accounted for most of the balance with

21 and 17 percent, respectively, of the total net

generation.

# Emissions

Electricity generators must adhere to rigorous

environmental r

egulations in the United States. Many

have invested billions of dollars in emissions reduction

technologies to meet these requirements. Nonetheless,

fossil fuel combustion continues to be the largest single

source of industrial air emissions according to the

United States Environmental Protection Agency 1



## .

Carbon dioxide emissions have continued to rise

steadily since 1990 resulting in a 23

- percent increase in

2001 over 1990 levels (Figure 8). On the other hand,

nitrogen oxides have steadily decreased i n the 1990

-

2000

- time period, with 2001 levels 11

- percent less than

they were in 1990. Despite rising during 1996

- 1998

and 2001, sulfur dioxide emissions are 12

- percent

lower than they were in 1990.

# Trade

Restructuring of the industry has dramatically

increased trade in some parts of the country. In 2001,

purchases by electric utilities increased to 2,976 billion

kilowatthours, a 32

- percent inc rease over 2000

purchases of 2,250 billion kilowatthours.



# Retail Customers, Sales, and

Revenues

1 See the EPA website at http://www.epa.gov/ cleanenergy/impacts/

impacts.htm#chart. 

## Total retail sales in 2001 were 3,370 million

megawatthours, down slightly from the 2000 level of

3,421 million megawatthours. This represents an

approximat e decrease of 0.6 percent. Further

examination shows the biggest decreases in retail sales

occurred on the West Coast, as a result of California’s

electricity crisis.

Sales between the three major sectors are relatively

well balanced in the United State s. The residential

sector, at 1,203 million megawatthours, is larger than

the commercial sector or industrial sector by

approximately 10 percent and 25 percent, respectively

(Figure 9).

# Revenue and Expense Statistics

In 2001, electric utility revenues once again surpassed

300 billion (Figure 1 1). Electric utility revenues and

expenses for 2001 differed among the various utility

ownership classes. Investor

- owned utilities (IOUs), by

far the largest ownership category, had increases in

both total revenues and total operating expenses. IOU

opera ting revenues were up by 14 percent to 268

billion, while operating expenses increased by 12

percent to 235 billion. Most of the increase in

expenses could be attributed to increases in production

costs and purchased power costs. Increased natural gas

co sts were a major cause of these increases.

Licensees and Others;” Rural Utilities Services (RUS)

Form 7, “Financial and Statistical Report;” and RUS

Form 12, “Operating Report

- Financial.”

Financial results for the other utility ownership types

differed sharply from those for IOUs . Revenues for

publicly owned utilities were up by 16 percent to 48

billion, but expenses increased by approximately 20

percent to 43 billion. Most of this could be accounted

for by the increased purchase power costs from 2000 to

2001. Federal utility revenues increased by 14 percent to 12

billion, while operating expenses increased by 20

percent to 10 billion. Most stable were the financial

results for cooperatively owned electric utilities

(cooperatives). Cooperatives reported annual revenue

increa ses of 3 percent to 26 billion, with expenses

increasing by only 3 percent to 24 billion. The

cooperatives’ costs and revenues were largely insulated

from market changes as a result of long

- term contracts.



# Demand

- Side Management

In 2001, the total peak

- load reductions from demand

side management (DSM) in 2001 were 24,955

megawatts, up 9 percent from 2000, and down 6

percent from 1999 (Figure 12). There has been a clear

and steady decline in peak

- load reduction from DSM

measures since 1996. This may refl ect a reduced

emphasis on integrated resource planning at State

regulatory commissions as the resource planning

process has become fragmented.

Notes: ·See Glossary for definitions.·Utilities and energy service providers may classify commercial and industrial customer s based on either NAICS codes or demands or usage falling

within limits specified by a rate schedule.·Changes from year to year in consumer counts, sales and revenues, particularly involving the commercial and industrial consumer sectors, may

result from r espondent implementation of changes in the definitions of consumers, and reclassifications.·As a consequence of unrecoverable high average wholesale power costs in

California in 2000 and early 2001, the credit ratings of California's three major investor

- o wned utilities fell below investment grade by early 2001. The rapid and dramatic decline in the

credit

- worthiness of California's major investor

- owned utilities virtually eliminated their ability through wholesale markets to meet the power requirements of their retail consumers. In

response to the looming energy shortfall, the California State legislature authorized the California Department of Water Resources (CDWR), using its undamaged borrowing capability, to

enter the wholesale markets on behalf of th e California retail consumer effective on January 17, 2001 and for the period ending December 31, 2002. Also the California Public Utility

Commission (CPUC) was required by statute to establish the procedures for facilitating the CDWR's participation in C alifornia retail sales, as well as retail revenue recovery mechanisms.

Energy provided by the CDWR was delivered by the major investor

- owned utilities in California. For this reason, and by agreement with the CDWR, energy sales for the calendar year

2001 of approximately 58.9 million megawatthours and associated revenue, related to the CDWR's intervention in the crisis, are identified as "Energy Only Providers."

2 For 2001, California Department of Water Resources

- Electric Energy Fund data were excluded from these statistics. In response to the looming energy shortfall in California, the

Calif ornia State legislature authorized the California Department of Water Resources, using its undamaged borrowing capability, to enter the wholesale markets on behalf of the California

retail customers effective on January 17, 2001, and for the period ending December 31, 2002. Their 2001 revenues collected were $5,501,000,000 with purchase power costs of

$12,055,000,000. The California Public Utility Commission was required by statute to establish the procedure for retail revenue recovery mechanisms for th ese purchase power costs in

the future.

and describes the reasoning behind the changes and their

effects on EIA forms and publications. Following is a

description of the ongoing data quality efforts and sources

of data for the Electric Power Annual

.



# Data Quality

The Ele ctric Power Annual (EPA) is prepared by the

Electric Power Division, Office of Coal, Nuclear, Electric

and Alternate Fuels (CNEAF), Energy Information

Administration (EIA), U.S. Depart ment of Energy.

Quality statistics begin with the collection of the c orrect

data. To assure this, the CNEAF office performs routine

reviews of the data collected and the forms on which it is

collected. Additionally, to assure that the data is collected

from the correct parties, CNEAF routinely reviews the

frames for each data collection.

Automatic, computerized verification of keyed input,

review by subject matter specialists, and follow

- up with

non

- respondents also assure quality statistics. To ensure

the quality standards established by the EIA, formulas that

use t he past history of data values in the database have

been designed and implemented to check data input for

errors automatically. Data values that fall outside the

ranges prescribed in the formulas are verified by

telephoning respondents to resolve any disc repancies.

Also survey non

- respondents are identified and contacted.



# Reliability of Data

Annual survey data have nonsampling errors. Non

sampling errors can be attributed to many sources: (1)

inability to obtain complete information about all cases in

the sample (i.e., nonresponse); (2) response errors; (3)

definitional difficulties; (4) differences in the

interpretation of questions; (5) mistakes in recording or

coding the data obtained; and (6) other errors of collection,

response, coverage, and estim ation for missing data.

Although no direct measurement of the biases due to

nonsampling errors can be obtained, precautionary steps

were taken in all phases of the frame development and

data collection, processing, and tabulation processes, in an

effort to minimize their influence. See the Data

Processing and Data System Editing section for each EIA

Form for an in depth discussion of how the sampling and

nonsampling errors are handled in each case.



# Data Revision Procedure The CNEAF office has adopted the following policy with

respect to the revision and correction of recurrent data in

energy publications:

1. Annual survey data collected by CNEAF are

published either as preliminary or final when

first appearing in a data report. Data initially

rel eased as preliminary will be so noted in the

report. These data will be revised, if necessary,

and declared final in the next publication of the

data.

2. All monthly survey data collected by this office

are published as preliminary. These data are

typ ically revised only after the completion of

the 12

- month cycle of the data. No revisions

are made to the published data before this

unless major errors are discovered that may

affect the national total.

3. The magnitudes of changes due to revisions ex

perienced in the past will be included in the data

reports, so that the reader can assess the

accuracy of the data.

4. After data are published as final, corrections

will be made only in the event of a difference of

one percent or greater at the natio nal level.

Correc tions for differences that are less than the

one percent or greater threshold are left to the

dis cretion of the Office Director.

The Electric Power Annual presents the most current

annual data available to the EIA. The statistics may di ffer

from those published previously in EIA publications due

to corrections, revisions, or other adjustments to the data

subsequent to its original release. On a chapter basis, the

status (preliminary versus final) of the data contained in

the EPA follows :

• Chapter 1, Generation Based on data from the

Form EIA

- 906. All data are final.

• Chapter 2, Capacity Based on data from the

Form EIA

- 860. All data are final.

• Chapter 3, Demand, Capacity Resources, and

Capacity Margins Based on data from the Form

The Form EIA

- 411 is filed annually as a voluntary report.

The information reported includes: (1) actual energy and

peak demand for the preceding year and five additional

years; (2) existing and future generating capacity; (3)

sc heduled capacity transfers; (4) projections of capacity,

demand, purchases, sales, and scheduled maintenance; and

(5) bulk power system maps. These reports present various

NERC Regional council aggregate totals for their member

electric utilities, with som e nonmember information

included.

Instrument and Design History. The Form EIA

- 411

program was initiated under the Federal Power

Commission Docket R

- 362, reliability and adequacy of

electric service, and Orders 383

- 2, 383

Department of E

nergy, established in October 1977,

assumed the responsibility for this activity. This form is

considered voluntary under the authority of the Federal

Power Act (Public Law 88

- 280), The Federal Energy

Administration Act of 1974 (Public Law 93

- 275), and the

Department of Energy Organization Act (Public Law 95

- 91). The responsibility for collecting these data had been

delegated to the Office of Emergency Planning and

Operations within the Department of Energy and was

returned to EIA for the reporting year 199 6.

Data Processing and Data System Editing. The 10

North American Electric Reliability Councils file the

Form EIA

- 411 annually on June 1. The forms are

compiled from data furnished by electricity generators

(members, associates, and nonmembers) within th e

council areas.

# Form EIA

-

412

The Form EIA

- 412 is a restricted

- universe census used

annually to collect accounting, financial, and operating

data from major p

ublicly owned electric utilities in the

United States. Those publicly owned electric utilities

engaged in the generation, transmission, or distribution of

electricity which had 150,000 megawatthours of sales to

ultimate consumers and/or 150,000 megawatthou rs of

sales for resale for the two previous years, as reported on

the Form EIA

- 861, “Annual Electric Utility Report,” must

submit the Form EIA

- 412. Beginning with the 2001 data

collection, the plant statistics reported on Schedule 9 were

also collected fro m unregulated entities that own plants

with a nameplate capacity of 10 MW or greater. Also

beginning with the 2002 collection, the transmission data

reported in Schedules 10 and 11 were collected from each

generation and transmission cooperative owing

tra nsmission lines having a nominal voltage of 132 kV or

greater. The 1999

- 1997 data represent those electric

utilities meeting a threshold of 120,000 megawatthours for

ultimate consumers' sales and or resales. The criteria used

to select the respondents for this survey results in

approximately 500 publicly owned electric utilities.

Federal electric utilities are required to file the Form EIA

412. The financial data for the U.S. Army Corps of

Engineers (except for Saint Mary's Falls at Sault Ste.

Marie, Michi

gan); the U.S. Department of Interior, Bureau

of Reclamation; and the U.S. International Boundary and

Water Commission were collected on the Form EIA

- 412

from the Federal power marketing administrations.

Instrument and Design History. The FPC created the

FPC Form 1M in 1961 as a mandatory survey. It became

the responsibility of the EIA in October 1977 when the

FPC was merged with DOE. In 1979, the FPC Form 1M

was superseded by the Economic Regulatory

Administration (ERA) Form ERA

- 412, and in January

1980 by the Form EIA

- 412. Data Processing and Data System Editing. The

processing of data reported on this survey is the

responsibility of the Electric Power Division within the

Office of Coal, Nuclear, Electric and Alternate Fuels. The

completed surveys ar

e due in this office on or before April

30. Non

- response follow

- up procedures are used to attain

100

- percent response. Edit checks of the data are

performed through computer programs. The program edits

include both deterministic checks, in which records a re

checked for the presence of data in required fields, and

statistical checks, in which the data are checked against a

range of values based on historical data values and for

logical or mathematical consistency with data elements

reported in the survey. D iscrepancies found in the data, as

a result of these checks, are resolved either by the

processing office or by further information obtained from

a telephone call to the respondent company.

Rounding Rules for Data. Not applicable.

Percent Difference. T he following formula is used to

calculate percent differences.

The Form EIA

- 767 is a mandatory restricted

- universe

census of all electric power plants with a total existing or

planned organic

- fueled or combustible renewable steam

electric generator nameplate rating of 10 or mor e

megawatts. The entire form is filed by approximately 700

power plants with a nameplate capacity of 100 or more

megawatts. An additional 600 power plants with a

nameplate capacity under 100 megawatts submit

information only on fuel consumption/quality,

bo iler/generator configuration, and flue gas desulfurization

equipment, if applicable. The Form EIA

- 767 is used to

collect data annually on plant operations and equipment

design (including boiler, generator, cooling system, flue

gas desulfurization, flue gas particulate collectors, and

stack data).

# Form EIA

- 860

Beginning with data collected for the year 200 1, the Forms

EIA

- 860A and EIA

- 860B are obsolete. The infrastructure

data collected on those forms are now collected on the

Form EIA

- 860 and the monthly and annual versions of the

Form EIA

- 906.

The Form EIA

- 860 is a mandatory census of all existing

and p lanned electric generating facilities in the United

States with a total generator nameplate capacity of 1 or

more megawatts. The survey is used to collect data on

existing power plants and 5

- year plans for constructing

new plants, generating unit additions , modifications, and

retirements in existing plants. Data on the survey are

collected at the gen

erator unit level.

Instrument and Design History. The Form EIA

- 860 was

originally implemented in January 1985 to collect plant

data on electric utilities as of year

- end 1984. In January

1999, the Form EIA

- 860 was renamed the Form EIA

860A and was implemented to collect data as of Ja nuary 1,

1999.

In 1989, the Form EIA

- 867, "Annual Nonutility Power

Producer Report," was initiated to collect plant data on

unr egulated entities with a total generator nameplate

capacity of 5 or more megawatts. In 1992, the reporting

threshold of the Form EIA

- 867 was lowered to include all

facilities with a combined nameplate capacity of 1 or more

megawatts. Previously, data were collected every 3 years

from facilities with a nameplate capacity between 1 and 5

megawatts. In 1998, the Form EIA

- 867, was renamed

Form EIA

# Form EIA

- 861

The Form EIA

- 861 is a mandatory census of electric

power industry participants in the United States. The

survey is used to collect information on power production

and sales data from approximately 4,900 respondents.

About 3,300 are electric utilities, and the remainder are

nontraditional entities such as independent power

producers, and the unregulated s ubsidiaries of electric

utilities. The data collected are used to maintain and

update the EIA's electric power industry participant frame

database.

Instrument and Design History. The Form EIA

- 861 was

implemented in January 1985 for collection of data as of

year

- end 1984. The Federal Administration Act of 1974

(Public Law 93

- 275) defines the legislative authority to

collect these data.

Data Processing and Data System Editing. The Form

EIA

- 861 is mailed to the respondents in January of each

year to co llect data as of the end of the preceding calendar

year. The data are edited when entered into the interactive

on

- line system. Internal edit checks are per formed to verify that current data total across and between sched ules,

and are comparable to data r eported the previous year.

Edit checks are also per formed to compare data reported

on the Form EIA

- 861 and similar data reported on the

Forms EIA

- 826 and the EIA

- 412, “Annual Electric

Industry Financial Report.” Respondents are telephoned to

obtain clari fication of reported data and to obtain missing

data.

Data for the Form EIA

- 861 are collected at the owner

level from all electric utilities in the United States, its

territories, and Puerto Rico. Form EIA

- 861 data in this

publication are for the United States only.

Average revenue per kilowatthour represents the cost per

unit of electricity sold and is calculated by dividing retail

electric revenue by the corresponding sales of electricity.

The average revenue per kilowatthour is cal culated for all

con sumers and for each end

- use sector. A ratio estimation

procedure is used for estimation of revenue per

kilowatthour at the State level.

The electric revenue used to calculate the average revenue

per kilowatthour is the operating revenue reported by the

e lectric power industry participant. Operating revenue

includes energy charges, demand charges, consumer

service charges, environmental surcharges, fuel

adjustments, and other miscellaneous charges. Electric

power industry participant operating revenues al so include

State and Federal income taxes and taxes other than

income taxes paid by the utility.

The average revenue per kilowatthour reported in this

publication by sector represents a weighted average of

consumer revenue and sales within sectors and a cross

sectors for all consumers, and does not reflect the per kWh

rate charged by the electric power industry participant to

the individual consumers. Electric utilities typically

employ a number of rate schedules within a single sector.

These alternative rate schedules reflect the varying

consumption levels and patterns of consumers and their

associated impact on the costs to the electric power

industry participant for providing electrical service.

Rounding Rules for Data. Given a number with r digits to

the left of the decimal and d+t digits in the fraction

part, with d being the place to which the number is to be

rounded and t being the remaining digits which will be

truncated, this number is rounded to r+d digits by adding 5

to the (r+d+1)th d

igit when the number is positive or by

# Form EIA

- 906

As of January 2001, Form EIA

- 906 superseded Forms

EIA

- 759 and 900. The Form EIA

- 906 is used to collect

monthly plant

- level data on generation, fuel consumption,

stocks, fuel heat content, and useful thermal output from

electric utilities and nonutilities from a model

- b ased

sample of approximately 260 electric utilities and 900

nonutilities. Fuel consumption for combined heat and

power facilities is apportioned between fuel for generation

of electricity and fuel for production of useful thermal

output, by assuming they are additive. Fuel usage for

these facilities is assumed to have an efficiency of 80

percent. The consumption for useful thermal output is

obtained by dividing the reported or estimated value for

useful thermal output by 0.8. This value is then subtract ed

from total fuel consumption by facility to arrive at the fuel

consumption to be associated with the generation of

electricity. The form is also used to collect these statistics

from the rest of the frame on an annual basis.

Instrument and Design Hist ory. In January 2001, Form

EIA

- 906 superseded Forms EIA

- 759 and EIA

- 900. The

Federal Administration Act of 1974 (Public Law 93

- 275)

defines the legislative authority to collect these data.

Relating to the Form EIA

- 759, the Bureau of Census and

the U.S. G

eological Survey collected, compiled and

published data on the electric power industry prior to

1936. After 1936, the Federal Power Commission (FPC)

assumed all data collection and publication responsibilities

for the electric power industry and implemente d the Form

FPC

- 4. The Federal Power Act, Section 311 and 312, and

FPC Order 141 define the legislative authority to collect

power production data. The Form EIA

- 759 replaced the

Form PFC

- 4 in January 1982.

In 1996, the Form EIA

- 900 was initiated to collect sales

for resale data from unregulated entities. In 1998, the form

was modified to collect sales for resale, gross generation,

and sales to end user data. In 1999, the form was modified

to collect net generation, consumption, and ending stock

data. In 200 0, the form was modified to include useful

thermal output data. Data Processing and Data System Editing. In 2001 and

2002, the Form EIA

- 906 was received by the EIA as a

hard copy, typically via fax, and manually entered into a

computerized database. An omalous data were identified

via range checks, comparisons with historical data, and

consistency checks (for example, whether the fuel

consumption and generation numbers for a given facility

and month are consistent).

The review of the Form EIA

- 906 filing s for non

- regulated

facilities in 2001 uncovered widespread problems with the

data reporting. The most prevalent problems were

reported fuel consumption inconsistent with generation

and, most significantly, incorrect reporting of useful

thermal output (UT O) by combined heat and power (CHP)

facilities.

UTO is the thermal output from a CHP facility applied to

a production process other than electricity generation.

Many facilities either misunderstood EIA’s definition or

did not meter internally such that t hey could easily

estimate CHP. This was an important problem in the data

collection effort. If UTO is reported incorrectly, then the

reported data cannot be used to estimate fuel for

electricity.

EIA’s preferred means of resolving any questionable

respo nse is via direct communication with the respondent,

usually via phone or e

- mail. In cases where the reported

data appeared to be incorrect or was missing, and EIA was

unable to resolve the matter with the respondent, the

following estimation approaches w ere used for the 2001

data:

• In cases where electric generation appeared

reasonable but fuel consumption was inconsistent

with generation, fuel consumption by prime

mover was estimated using 2000 heat rates and

the assumption that the fuel shares for that prime

mover in 2001 were the same as in 2000.

• If the reported electric generation data appeared

to be in error, or if the facility was a non

respondent, a regression methodology was used

to estimate generation and fuel consumption for

the facility. The re gression methodology relied

on 2000 and 2001 data for other facilities to make

estimates for erroneous or missing responses.

The basic technique employed is described in the

paper Model

- Based Sampling and Inference,

found on the EIA web site at

http://www.eia.doe.gov/cneaf/electricity/page/for

ms.html

.

• UTO was estimated by applying the power to

steam ratio calculated for the facility in 2000 to

2001.

    Overall, of the approximately 260 0 facilities in the Form

EIA

- 906 frame for 2001, some estimation was performed

for 803 facilities. These facilities account for

approximately 4 percent of the generation in the frame and

about 20 percent of the fuel consumption.

Relative Standard Error. The relative standard error

(RSE) statistic, usually given as a percent, describes the

magnitude of sampling error that might reasonably be

incurred. The RSE is the square root of the estimated

variance, divided by the variable of interest. The variable

o f interest may be the ratio of two variables, or a single

variable.

The sampling error may be less than the nonsampling

error. In fact, large RSE estimates found in preliminary

work with these data have often indicated nonsampling

errors, which were then identified and corrected.

Nonsampling errors may be attributed to many sources,

including the response errors, definitional diffi culties,

differences in the interpretation of questions, mistakes in

recording or coding data obtained, and other errors of

co llection, response, or coverage. These non sampling

errors also occur in complete censuses. In a complete

census, this problem may become unman ageable.

Using the Central Limit Theorem, which applies to sums

and means such as are applicable here, there is approxi

mately a 68

- percent chance that the true sampling error is

less than the corresponding RSE. Note that reported RSEs

are always estimates, themselves, and are usually, as here,

reported as percents. As an example, suppose that a net

generation fr om coal value is estimated to be 1,507 million

kilowatthours with an estimated RSE of 4.9 percent. This

means that, ignoring any nonsampling error, there is

approximately a 68

- percent chance that the true million

kilowatthour value is within approximately 4.9 percent of

1,507 million kilowatthours (that is, between 1,433 and

1,581 million kilowatthours). There is approxi mately a

95

- percent chance of a true sampling error being 2 RSEs

or less.

Note that there are times when a model may not apply,

such as in the case of a substantial reclassification of sales,

when the relationship between the variable of interest and

the regressor data does not hold. In such a case, the new

information represents only itself, and such numbers are

added to model results w hen estimating totals. Further,

there are times when sample data may be known to be in

error, or are not reported. Such cases are treated as if they

were never part of the model

- based sample, and values are

imputed.

Adjusting Monthly Data to Annual Data

. As a final

adjustment based on our most complete data, use is made

of annual Form EIA

- 906 data, when available. The annual totals of the monthly Form EIA

- 906 data by State and end

use sector are compared to the corresponding annual Form

EIA

- 861 values f

or sales and revenue. The ratio of these

two values in each case is then used to adjust each

corresponding monthly value.

Average Heat Content. The average heat content values

collected on the Form EIA

- 906 were used to convert the

consumption data into B tu. Therefore, the results may not

be completely representative.

Rounding Rules for Data. Given a number with r digits

to the left of the decimal and d+t digits in the fraction part,

with d being the place to which the number is to be

rounded and t being the remaining digits which will be

truncated, this number is rounded to r+d digits by adding 5

to the (r+d+1)th digit when the number is positive or by

subtracting 5 when the number is negative. The t digits

are then truncated at the (r+d+1)th digit. The symbol for a

number rounded to zero is (*).

Percent Difference. The following formula is used to

calculate percent differences.

Percent Difference =

where x (t 1 

## ) and x (t 2 

## ) denote the quantity at year t 1 

## and

subsequent year t 2



## .

Confidentiality of the Data. Most of the data collected

on the Form EIA

- 906 are not considered confidential.

However, the reported fuel stocks at the end of the

reporting period are con sidered con fidential and must

adhere to EIA's “Policy on the Disclosure of Individua lly

Identifiable Energy Infor mation in the Possession of the

EIA” (45Federal Register 59812 (1980)).

Conversion of Petroleum Coke to Liquid Petroleum.

The quantity conversion is 5 barrels (of 42 U.S. gallons

each) per short ton (2,000 pounds). Coke from petroleum

has a heating value of 6.024 million Btus.

# Air Emissions

This section describes the methodology employed to

calculate estimates of carbon dioxide (CO 2 

## ), sulfur dioxide

(SO 2 

## ), and nitrogen oxides (NO X 

## ) emissions from electric

generating plants.

The CO 2 

## air emissions are estimated using information

contained on Form EIA

- 906, “Power Plant Report.” The

Form EIA

- 906 collects information from all electric power

plants in the United States either monthly or annually.

Data collected on this form incl ude electric power

generation, energy source consumption, and useful

thermal output from combined heat and power producers.

The Form EIA

- 906 sample of monthly respondents is a

representation of electric power plants by State and by

energy source. Electric power plants that do not report

data monthly are to submit data annually on this form.

The SO 2 

## and NO X



## air emissions are estimated using

information contained on Form EIA

- 767, “ Steam

- Electric

Plant Operation and Design Report.” Form EIA

- 767

collects inf

ormation annually for all U.S. power plants

with a total existing or planned organic

- fueled or

combustible renewable steam

- electric plant that has a

generator nameplate rating of 10 megawatts or larger. If a

plant has a nameplate capacity of 100 megawatts or

greater, the entire form must be completed which provides

information about fuel consumption and quality, legal air

emission limits, and flue gas desulfurization (FGD). If a

plant has a nameplate rating of 10 megawatts, but less than

100 megawatts, on ly part of the form must be completed

which provides information on fuel consumption and

quality, NO

X 

## emission controls, and FGD sulfur removal

efficiency, if applicable. The SO 2 

## and NO X 

## calculations

are reduced for plants that have the Environmental

Prot ection Agency’s Continuous Emissions Monitoring

System.

Uncontrolled Air Pollutant Emissions. Uncontrolled air

pollutant emissions are those emissions that would occur

in the absence of any control equipment. Uncontrolled

CO 2 

## , SO 2 

## , and NO X



## emissions are determined by

multiplying the quantity of fuel burned by an emission

factor. An emission factor is the average quantity of a

pollutant released from a boiler when a unit of fuel is

burned.

The coefficients for determining emissions of CO 2 

## from

electric po wer plants come from the publication,

Emissions of Greenhouse Gases in the United States,

(DOE/EIA

- 0573). The source of the SO 2 

## and NO X



## emission factors, when available, is the Environmental

Protection Agency report AP

- 42, “Compilation of Air Pollutant Em ission Factors” (Tables A1 and A3). 1



## Emissions of SO 2 

## and NO X 

## have been revised from the

updated Air Pollutant Emissions Factor (AP

- 42 5th

edition, through Supplement E) of the Environmental

Protection Agency on July 1999. Environmental

Protection Agency e

mission factors are based on boiler

type, firing configuration, and fuel burned.



# Methodology

CO 2 

## emissions for power producers include emis sions

from combined heat and power (CHP) facilities that

produce electric power as an integral part of a

manufa cturing or other thermal consuming process.

Emissions are directly propor tional to the quantities of

fuels consumed. To calculate emissions for the production

of electricity, a methodology was developed to estimate

the consumption of fuel associated for t he production of

electricity by CHP facilities. The methodology is based on

the following:

1. A steam boiler efficiency rate of 80 percent was

assumed.

2. The reported or estimated value for useful thermal

output (in Btu) was divided by 0.8 to estimate th e fuel

used to generate this amount of thermal output.

3. This value was subtracted from total fuel con sumption

and the remainder was assumed to be the amount used for

electric generation.

Coal Rank and Emissions. In 1992, a special study of the

relation ship between the heat and carbon content of coal

was completed by the Energy Information

Administration's Analysis and Systems Division of the

Office of Coal, Nuclear, Electric and Alternate Fuels. The

hypothesis underlying this study was that the ratio of

carbon

- to

- heat content varies not only by coal rank (i.e.,

anthracite, bituminous, subbituminous, and lignite), but

also by geographic location of the coal. In this study, the

hypothesis was tested and the results of the analysis

supported the hypothesis. That is, it was concluded from

the analysis that coal rank and location of the coal are

significant factors in the variation of the ratio of carbon

to

- heat content. After this determination, a set of emission

factors, by rank and State were derived on the basis of data

contained in EIA's Coal Analysis File. 2

## For a description of the methodology and data used to

develop the EIA CO22 emission factors, see B. D. Hong

and E. R. Slatick, “Carbon Dioxide Emission Factors for

Coal,” Quarterly Coal Re port, January

- March 1994,

## Energy Information Administration/Electric Power Annual 2001 67



## In editions prior to 1992 of this publication, separate

conversion factors by coal rank were published and used

to estimate emissions of CO 2 

## . The special study by EIA

concluded that since geographic l ocation of coal in

addition to rank of coal is a significant factor in

determining the carbon/heat content relationship, the use

of emission factors that consider both of these elements

may yield more accurate estimates of CO 2 

## emissions. The

emission facto rs for coal were developed in the units of

pounds of CO 2 

## per million Btu of coal.

The emission factors for CO 2 

## (Table A2) from coal are

applied by power plant, based on the rank, amount of coal

received, and the State from which the coal originated, as

re ported in FERC Form 423, “Cost and Quality of Fuels

for Electric Plants.” Thus, a weighted average emissions

factor is obtained by plant and multiplied by the quantity

of coal consumed by plant, as reported on Form EIA

- 906,

“Power Plant Report,” to determi ne the emissions of CO 2



## . The emission factors for CO 2 

## are based on 100

- percent

combustion of the carbon in the fuel. Since a small

percentage of the carbon in the coal is not converted to

CO 2 

## , this publication assumes 99 percent combustion. The

1 percent o

f emissions is deducted at the State/National

level. The emissions at the State level are based on the

State in which the plant is located. Uncontrolled

emissions of SO 2 

## and NO X 

## do not always accurately depict

the quantity of emissions released into the atmosphere

because they fail to reflect reductions from control

equipment and/or operating technologies. Consequently,

controlled emissions are calculated to provide a more

accurate estimate of actual air emissions.

Controlled Sulfur Dioxide Emissions. Be cause of

environmental regulations controlling SO 2 

## emissions,

many generating plants are required to install FGD units at

their coal

- fired plants.

3 

## FGD units typically remove

between 70 to 90 percent of SO 2 

## from the boiler flue gas

although higher removal efficiencies can be achieved.

Electric generating plants report both sulfur removal

efficiency (percent) and their most stringent SO 2 

## emission

limits on the Form EIA

- 767. To determine controlled SO 2 

## emissions, the uncontrolled emissions are reduced by the

annual average removal efficiencies reported on the Form

EIA

- 767. This emission is the controlled emission. As a

check, the controlled emission is compared with the most

stringent legal limit reported on the Form EIA

- 767. The

controlled emission should be less than the legal limit

because research indicates that electric generating plants

routinely remove more SO 2 

## than required to assure an

DOE/EIA

- 0121(94/1Q) (Washington, DC, August 1994),

Energy Information Administration.

3

Flue gas desulfurization units may also reduce sulfur dioxide emissions from

plants that burn oil and petroleum coke. 

## operating margin of safety. If the controlled emission is

not less than the most stringent legal limit, it implies tha t

the plant or facility is out of legal compliance and could be

subject to fines and other penalties.

Electric generating plants are permitted to take credit for

sulfur that remains in bottom ash

– ash remaining in the

bottom of the furnace after the coal is burned. For

example, if a plant or facility is required to remove 90

percent of the sulfur in the coal and 3 percent remains in

the ash, it has to remove only 87 percent using scrubbers.

This credit is included in emissions data in this report. It is

l ikely, however, that in many cases the credit is not taken.

In order to take the ash credit, generating facilities need to

monitor the coal consumed on a daily basis; this is both

time

- consuming and costly. To the extent that generating

facilities do not t

ake the ash credit, emissions might be

slightly overstated.

Sulfur Dioxide Emission Comparison. Title IV of the

Clean Air Act Amendments of 1990 requires annual sulfur

dioxide (SO 2 

## ) emissions from electric power plants to be

reduced 10 million tons below their 1990 level by the year

2010. The Clean Air Act required electric generating units

covered under the Acid Rain Program (units 25 megawatts

and greater) to be equipped with continuous emission

monitoring systems (CEMS). CEMS is the industry

standard fo r measuring and recording hourly SO 2 

## , nitrogen

oxide (NO

X 

## ), and carbon dioxide (CO 2 

## ) emissions. In

1994, the first 263 generating units covered under the Acid

Rain Program were required to install CEMS and submit a

year's worth of emissions data to the Env ironmental

Protection Agency (EPA). In 1995, the operators of more

than 2,000 additional units were required to measure and

report emissions data. EPA started publishing CEMS

emissions data by State and plant in its publication Acid

Rain Program, Emissions Scorecard (EPA430/R

- 97

- 025).

Controlled Nitrogen Oxide Emissions. The controlled

NO X 

## emission is calculated by applying the appropriate

reduction factor in Table A4. Prior to 1995 for boilers with

regulated nitrogen oxide emission limits, the annual

con trolled estimate used was the lesser of the controlled

estimate or the annual limitation. When more than one

control technology is reported, the highest single reduction

factor is used to estimate the annual controlled NO X 

## emission. A degree of complexi ty is added to this

approach, however, because air emission standards are not

reported in consistent units. In some rare instances,

emission standards are reported in units that cannot be

directly compared with estimated uncontrolled emission

rates. Exampl

es of such standards are ones that specify the

concentration of NO X



## allowed in the flue gas or the

ambient concentration of NO X 

## (parts per million). In cases

where these types of standards are reported, the

uncontrolled emission estimate is used. Such sta ndards

## Energy Information Administration/Electric Power Annual 2001

68 

## are uncommon, however, and do not significantly affect

the results.

Carbon Dioxide Emissions. There are no Federal

regulations that limit CO 2 

## emissions. Information pertinent

to the estimation of controlled CO 2 

## emissions is not

collected on the For

m EIA

- 767; therefore, no estimates of

controlled CO

2 

## emissions are made.

Air Emissions from Small Plants. The Form EIA

- 767

does not collect data for generators powered by internal

combustion engines, gas turbines, combined cycle units

(for example, gas turbines with waste heat boilers), and

boilers at steam

- electric plants with a total nameplate

capacity of less than 10 MW. Accordingly, air emissions

from these generators are not estimated by the

methodology. An estimate of air emissions from these

gener ating units based on a similar methodology using

consumption data reported on the Form EIA

- 906, “Power

Plant Report,” and predecessor forms was performed.

# Appendix B



# Estimating and Presenting Power Sector Fuel Use

I. Background

T he Energy Information Administration (EIA) has comprehensively reviewed and revised how it collects, estimates, and reports

fuel use for facilities producing electricity. The review addressed inconsistent reporting of the fuels used for electric power and

changes in the electric power marketplace that have been inconsistently represented in various EIA survey forms and publications.

For example:

• In some cases fuel use by combined

- heat

- and

- power (CHP) plants 1 

## has been reported as industrial sector fuel us e, while in

other cases it has been reported as electric power sector fuel use.

• Electricity generation and fuel consumption have been categorized and reported in several different ways, such as (1)

utility only; (2) utility and independent power producers ; or (3) utility, independent power producers, and CHP plants.

The restructuring of the power industry is making some of these categories less meaningful.

The goal of EIA’s comprehensive review was to improve the quality and consistency of its electric p ower data throughout all data

and analysis products. Because power facilities operate in all sectors of the economy (e.g., in commercial buildings, such as

hospitals and college campuses, and industrial facilities, such as paper mills and refineries) and use many fuels, any change to

electric power data affects data series in nearly all fuel areas and causes changes in a wide variety of EIA publications.

As a result of the comprehensive review, EIA has made the following changes:

• EIA has adjusted all pre sentations of data on electric power to a consistent format and defined the electric power sector to

include electricity

- only and CHP plants whose primary business is to sell electricity, or electricity and heat, to the public.

• EIA is providing detail with in the electric power sector, commercial sector, and industrial sector on fuel used by CHP

plants in those sectors.

• EIA has changed the sources of data on fuel used by components of the electric power sector. All tabulations and

publications will use dat a obtained from EIA’s surveys of electric power generators. This change in data source

contributes to changes in total fuel consumption of natural gas.

• EIA has revised its historical data on electric power to resolve data anomalies. The revisions contrib ute to changes in

EIA’s electricity series as well as the fuel

- use series.

Appendix B describes the reasoning behind the changes and their effect on electric power publications. It is organized as follows:

• Section II provides an overview of the key chan ges.

• Section III provides specific information for electric power publications.

The Annual Energy Review (AER) 2001, the first of the annual publications to be released with the new formats, provides detail on

changes for publications on coal, natural gas , petroleum, renewable energy, and greenhouse gas emissions.

II. Overview of Key Changes

The many changes that will occur because of the fuel review generally fall into three broad categories: (1) the categorization of

electric power facilities, (2) t he reporting of combined

- heat

- and

- power plant fuel use, and (3) data series revisions resulting from

revised electric power fuel use estimates. Each of these areas is discussed below.

Categorization of Electric Power Facilities

Until the 1990s, most ele ctric power generation and fuel use data could be meaningfully categorized into electric utilities and

nonutility power producers. 2 

## Electric utilities were generally structured as vertically integrated 3 

## power companies that were

1 Combined

- heat

- and

- powe r plants (CHP) produce both electricity and useful thermal output. EIA formerly referred to these plants as cogenerators, but has determined that CHP better

describes the facilities because some of the plants included in EIA’s data do not produce heat an d power in a sequential fashion, and as a result do not meet the legal definition of

cogeneration specified in the Public Utility Regulatory Policies Act (PURPA).

2 For an example of this, see Electric Power Annual 1998, Volume II , DOE/EIA

- 0348(98)/2, Dece mber 1999.

3 In this context “integrated” means that the company is involved in the three main sectors of the electric power business

— generation, transmission, and distribution.

## Energy Information Administration/Electric Power Annual 2001

76 

## responsible for generating , transmitting, and distributing power to consumers within their franchised service territory. Nonutility

power producers were generally independent generators

— mostly combined

- heat

- and

- power plants

— that produced some power for

their own use and sold the r emainder to utilities for distribution to consumers. However, in recent years, many formerly integrated

utilities have split apart, spinning off the generating part of their business into separate companies. Independent developers have

built most of the new generating capacity that has been installed in recent years. As a result, the distinction between utility and

nonutility power plants has become much less meaningful. In fact, a large portion of the growth in nonutility generation in recent

years is due to the reclassification of utility power plants as nonutility power plants.

To reflect the changing industry structure, EIA is now organizing electric power generation and fuel use data into two new

categories: electricity

- only and combined

- heat

- and

- power (CHP) plants. These categories separate power plants by function; i.e.,

power only or power plus thermal, rather than by ownership class.

Electricity

- only plants represent all plants, whether owned by utilities or nonutilities that produce only ele ctricity. CHP plants

represent entities that produce both electricity and some form of thermal energy. Both categories will have some facilities that are

owned by traditional utilities and independent companies.

In addition, EIA is now presenting data f or an electric power sector that includes electricity

- only plants and CHP plants whose

primary business is to sell electricity, or electricity and heat, to the public (North American Industry Classification System code

22). This contrasts with some previo us data presentations in which the electric power sector included industrial and commercial

CHP plants as well. Figure B1 provides an example from the Annual Energy Review (AER).

## In some tables and publications, the electric power sector will con tinue to be broken down into electric utilities and independent

power producers for customers who have expressed an interest in this breakout. For example, Table 8.1 of AER 2001 presents an

electricity overview and shows data on net generation for electri c utilities and independent power producers separately. It is the

only table in AER 2001 that has this break

- out (Figure B2).

is resulting in a reclassification of plants from electric utilities to independent power producers.

## Reporting of CHP Facility Fuel Use

Historically, f

uel consumption in CHP plants has been combined with other uses in many EIA publications. For example, in some

tables the use of natural gas in commercial and industrial CHP plants was included with other commercial and industrial uses.

Further, some of the fuel consumption (the portion associated with electricity production) at these same facilities was also reported

under the column labeled “Nonutility Power Producers.” Based on questions received, it became clear that this categorization led

to confus ion for many EIA customers.

EIA is now distinguishing within the industrial, commercial, and electric power sectors what portion of fuel consumption is used in

CHP facilities and non

- CHP facilities. For example: Electric Power Sector

Utilities Nonutility

Producers Total

## Energy Information Administration/Electric Power Annual 2001 77



# • In tabulations of energy use by economic sector, if a commercial or industrial facility has a CHP unit, the total fuel

consumption for that unit will be reported under commercial or industrial, but it will be identified separately from other

commercial or industrial consumption. CHP plants that report their primary business is generating and selling power to

others will be reported in a separate column in the electric power sector.

• In tabulations of energy use to produce electric power, the total fuel consumption reported by CHP plants will be further

separated into that which is used to produce electricity and that which is used to produce thermal energy. 4

## The separation between electricity and thermal uses is being done because many EIA data users have expressed interest in knowing

how much fuel is used to produce electricity in the United States.

Data Series Revisions Resulting From Chan ges in Electric Power Fuel Use Estimates

The revisions to electric power data affect many areas. For example, historically, to estimate natural gas use, EIA surveyed natural

gas pipeline

- companies and local gas utilities to obtain data on natural gas use d by residential, commercial, industrial, and electric

utility sectors, and nonutility generators

. 5 

## However, EIA also surveyed electric utilities on their natural gas use. These data

obtained directly from the end user were generally thought to be more a ccurate than the data obtained from natural gas suppliers.

As a result, total natural gas use was estimated by adding together the data from natural gas companies on residential, commercial,

industrial, and nonutility power producer use to the amount repo rted directly by electric utilities. The data collected for nonutility

power producers were included with industrial use in previous EIA natural gas publications.

With the changing structure of the electricity sector, this reporting approach no longer ap pears reasonable. EIA has decided to

follow the procedure described for electric utilities and use data obtained from its direct surveys of nonutility electric generators

rather than the natural gas supplier surveys. 6

4 For the method used to separate the fuel used at CHP plants between electric ity and useful thermal energy production, see Section III.

- 906, “Power Plant Report.”

## Energy Information Administration/Electric Power Annual 2001

78 

## Data changes are also occurring because of the extensive review of reported data that was undertaken in this process. Since it was

decided that data reported directly by utilities and nonutility power generators would be the primary source of fuel consumption

data for the power sector, an examination of heat rates, 7 

## capacity factors, 8 

## and power

- to

- steam ratios across 12 years of reported

data was conducted. As a result, data for nonutility power producers for 1989 through 2000 have been revised. The data review

procedure is described i n Section III under the heading “Efforts to Improve Data.” As a result of the review by expert EIA

analysts, anomalous values have been investigated and resolved and the result is higher quality data at aggregated levels.

Revisions resulting from changin g the source of fuel consumption data for nonutilities and from EIA’s data review affect data

beyond the category of nonutilities. Appendix H of AER 2001 provides examples.

III. Electric Power Surveys and Publications

Summary of Key Changes

EIA pr eviously presented data on electric power, such as generation and fuel consumption, in the following categories:

• Electric utilities,

• Nonutility power producers (independent power producers and combined

- heat

- and power plants),

• Electric power industry (sum of electric utilities and nonutility power producers).

Now EIA is presenting data for the following new categories:

• Electricity

- only

- plants

• Combined

- heat

- and

- power (CHP) plants,

• U.S. power producers (sum of electricity

- only plants and CHP plants and equa l to the prior “electric power industry”

category).

Data on electricity

- only plants are disaggregated for utilities and independent power producers, as there are customers who are

interested in maintaining this distinction. Data on CHP plants are disaggr egated by the end

- use category (commercial, industrial,

electric power) they report as their major line of business. The categorization is based on their North American Industrial

Classification System code. For example, a CHP plant that is part of a hos pital will be classified as “commercial.” Similarly, a

CHP plant that reports that it is part of a paper mill will be classified as “industrial,” and a plant that reports that its primary

business is selling power to others will be classified as “electric power.”

In addition, EIA has estimated and is presenting data on the amount of fuel used to generate electricity and the amount of fuel used

for useful thermal output. Furthermore, during the course of recategorizing the data, EIA performed a thorough d ata quality review

and revised data to resolve anomalies.

Efforts to Improve Data

EIA reviewed electric power

- data from 1989 through 2001 to determine whether there were anomalies. The 1989

– 2000 data for

nonutilities were from Form EIA

- 860B, “Annual Ele ctric Generator Report

- Nonutility,” and its predecessor, Form EIA

- 867,

“Annual Nonutility Power Producer Report.” The 2001 data are from Form EIA

- 906, “Power Plant Report.” These forms collect

data on fuel consumption, generation, and, with the exception of 1995 through 1997, useful thermal output. When anomalies were

identified in the data for the more recent years (1998

– 2001), EIA contacted selected respondents to resolve the inconsistencies.

For the historical data it was not possible to contact resp ondents. In this situation EIA made data adjustments to resolve the

anomalies.

EIA reviewed data for facilities with heat rates greater than 40,000 Btu per kilowatthour and less than 5,500 Btu per kilowatthour.

The upper limit was chosen to allow for th e heat rates of older non

- electricity boilers. In addition, EIA reviewed data for facilities

with overall efficiency of greater than 100 percent and identified facilities with thermal output that were not designated as CHP

plants. To ensure consistency, EIA compared North American Industry Classification System (NAICS) codes, cogenerator status,

fuel consumption, electric generation, and thermal output levels over time. Moreover, EIA analysts also reviewed and evaluated

aggregate

- level data by State, NAIC S code, fuel type, and generator type. For the historical data (1989

– 1997), EIA also:

7 Heat rates are computed by dividing the heat content of the fuel burned to generate electricity by the resulting net kilowatthour generation.

8 Capacity factors are the ratio of the electrical energy produced by a generating unit for the period of time c onsidered to the electrical energy that could have been produced at continuous

full power operation during the same period.

## Energy Information Administration/Electric Power Annual 2001 79



## • Estimated a value for useful thermal output for 1995 through 1997 (when useful thermal output was not included on the

survey form) that produced a heat rate between 5,5 00 and 40,000 Btu per kilowatthour and an efficiency rate consistent

with that observed in other years (see discussion below on CHP fuel use methodology).

• Corrected errors in units reported for fuel consumption.

• Compared data on fuel consumption with data on electric generation and adjusted data on fuel consumption or generation

to maintain a consistent ratio.

• Adjusted data on useful thermal output for those respondents with heat rates outside the 5,500

- to

- 40,000 Btu per

kilowatthour range and an efficiency rate consistent with other years.

The review included an examination of both respondent

- level data and aggregate

- level data. For the 1998

- 2000 data, the review

also included a comparison for consistency with data reported by manufacturing plants on Form EIA

- 3, “Quarterly Coal

Consumption

— Manufacturing Plants,” since a subset of the EIA

- 3 manufacturing plants generate electricity and also reported on

the electric generator survey Form EIA

- 860B. In general, there was good correspondence between the data s ubmissions. In

situations where there were inconsistencies, selected respondents were contacted to explain the differences. The analysis revealed

that in some instances there were legitimate explanations for high percentage differences, such as a respond ent reporting data for a

facility on one survey that should not be included in the other survey.

Allocating CHP Fuel Use

Because respondents do not keep records on how much fuel a CHP plant uses exclusively to produce electricity, EIA developed the

follo wing method for estimating how the total fuel consumed in the boiler is split between electricity generation and useful thermal

output:

• First, a steam boiler efficiency rate of 80 percent was assumed 9



## • Then the reported or estimated value for useful thermal output (in Btu) was divided by 0.8 to estimate the fuel used to

generate this amount of thermal output.

• Next, this value was subtracted from total fuel consumption and the remainder was assumed to be the amount used for

electric generation.

Electric Powe r Publication Tables Affected

In both the Electric Power Monthly and the Electric Power Annual :

• Data will be shown for the following categories throughout most of the report: (1) U.S. power producers, (2) electricity

only plants, and (3) CHP plants (com mercial, industrial, and electric power). Data on fuel consumption are shown for

both electric generation and thermal output.

• The lowest level of aggregation is at the State level.

• Data on petroleum coke are converted to barrels and included in petroleum consumption and stocks tables.

• Fuel types are revised to be consistent with the Annual Energy Review.

# Glossary

Anthracite: The highest rank of coal; used primarily for

residential and commercial space heating. It is a hard,

brittle, and black lustrou s coal, often referred to as hard

coal, containing a high percentage of fixed carbon and a

low percentage of volatile matter. The moisture content of

fresh

- mined anthracite generally is less than 15 percent.

The heat content of anthracite ranges from 22 to 28

million Btu per ton on a moist, mineral

- matter

- free basis.

The heat content of anthracite coal consumed in the

United States averages 25 million Btu per ton, on the as

received basis (i.e., containing both inherent moisture and

mineral matter). Note: S ince the 1980's, anthracite refuse

or mine waste has been used for steam electric power

generation. This fuel typically has a heat content of 15

million Btu per ton or less.

Ash: Impurities consisting of silica, iron, aluminum , and

other noncombustible ma tter that are contained in coal.

Ash increases the weight of coal, adds to the cost of

handling, and can affect its burning characteristics. Ash

content is measured as a percent by weight of coal on a

"received" or a "dry" (moisture

- free, usually part of a

laboratory analysis) basis.

Ash Content: The amount of ash contained in the fuel

(except gas) in terms of percent by weight.

Average Revenue per Kilowatthour: The average

revenue per kilowatthour of electricity sold by sector (resi

dential, commercial, in dustrial, or other) and geographic

area (State, Census division, and national), is calculated by

dividing the total monthly revenue by the corresponding

total monthly sales for each sector and geographic area.

Barrel: A unit of volume equal to 42 U.S. gall ons.

Biomass: Organic non

- fossil material of biological origin

constituting a renewable energy resource.

Bituminous Coal: A dense coal, usually black, sometimes

dark brown, often with well

- defined bands of bright and

dull material, used primarily as fuel in steam

- electric

power generation, with substantial quantities also used for

heat and power applications in manufacturing and to make

away in refinery operations. It conforms to ASTM

Specifications D 396 and D 975 and Federal Specification

VV

- F

- 815C. No. 5, a residual fue l oil of medium

viscosity, is also known as Navy Special and is defined in

Military Specification MIL

- F

- 859E, including Amend

ment 2 (NATO Symbol F

- 770). It is used in steam

powered vessels in government service and inshore

powerplants. No. 6 fuel oil incl udes Bunker C fuel oil and

is used for the production of electric power, space heating,

vessel bunkering, and various industrial purposes.

Retail: Sales covering electrical energy supplied for

residential, commercial, and industrial end

- use purposes.

Othe r small classes, such as agriculture and street lighting,

also are included in this category.

Revenues: The total amount of money received by a firm

from sales of its products and/or services, gains from the

sales or exchange of assets, interest and divid ends earned

on investments, and other increases in the owner's equity

except those arising from capital adjustments.

Sales: The transfer of title to an energy commodity from a

seller to a buyer for a price or the quantity transferred

during a specified per iod.

Sales for Resale: A type of wholesale sales covering

energy supplied to other electric utilities, cooperatives,

municipalities, and Federal and state electric agencies for

resale to ultimate consumers.

Service Classifications (Sectors): Consumers gro uped by

similar characteristics in order to be identified for the

purpose of setting a common rate for electric service.

Usually classified into groups identified as residential,

commercial, industrial and other.

## Service to Public Authorities: Public aut hority service

includes electricity supplied and services rendered to

municipalities or divisions or agencies of State and

Federal governments, under special contracts or

agreements or service classifications applicable only to

public authorities.

Solar Energy: The radiant energy of the sun that can be

converted into other forms of energy, such as heat or

electricity. Electricity produced from solar energy heats a

medium that powers an electricity

- generating device.

State Power Authority: A nonprofit uti lity owned and

operated by a state government agency, primarily involved

in the generation, marketing, and/or transmission of

wholesale electric power.

Steam

- Electric Power Plant (Conventional): A plant in

which the prime mover is a steam turbine. The stea m used

to drive the turbine is produced in a boiler where fossil

fuels are burned.

Stocks of Fuel: A supply of fuel accumulated for future

use. This includes coal and fuel oil stocks at the plant site,

in coal cars, tanks, or barges at the plant site, or in separate

storage sites.

Subbituminous Coal: A coal whose properties range

from those of lignite to those of bituminous coal and used

primarily as fuel for steam

- electric power generation. It

may be dull, dark brown to black, soft and crumbly, at the

lo wer end of the range, to bright, jet black, hard, and

relatively strong, at the upper end. Subbituminous coal

contains 20 to 30 percent inherent moisture by weight. The

heat content of subbituminous coal ranges from 17 to 24

million Btu per ton on a moist, mineral

- matter

- free basis.

The heat content of subbituminous coal consumed in the

United States averages 17 to 18 million Btu per ton, on the

as

- received basis (i.e., containing both inherent moisture

and mineral matter).

Sulfur: A yellowish nonmetallic e lement, sometimes

known as "brimstone." It is present at various levels of

concentration in many fossil fuels whose combustion

releases sulfur compounds that are considered harmful to

the environment. Some of the most commonly used fossil

fuels are categor

ized according to their sulfur content,

with lower sulfur fuels usually selling at a higher price.

Note : No. 2 Distillate fuel is currently reported as having

either a 0.05 percent or lower sulfur level for on

- highway

vehicle use or a greater than 0.05 per cent sulfur level for

off

- highway use, home heating oil, and commercial and

industrial uses. Residual fuel, regardless of use, is

classified as having either no more than 1 percent sulfur or

greater than 1 percent sulfur. Coal is also classified as

being l ow

- sulfur at concentrations of 1 percent or less or

high

- sulfur at concentrations greater than 1 percent.

Sulfur Content: The amount of sulfur contained in the

fuel (except gas) in terms of percent by weight. Supplemental Gaseous Fuel Supplies: Syntheti c natural

gas, propane

- air, coke oven gas, refinery gas, biomass gas,

air injected for Btu stabilization, and manufactured gas

commingled and distributed with natural gas.

Synthetic Fuel: A gaseous, liquid, or solid fuel that does

not occur naturally. S ynfuels can be made from coal (coal

gasification or coal liquefaction), petroleum products, oil

shale, tar sands, or plant products. Among the synfuels

are various fuel gases, including but not restricted to

substitute natural gas, liquid fuels for engine s (e.g.,

gasoline, diesel fuel, and alcohol fuels) and burner fuels

(e.g., fuel heating oils).

Terrawatt: One trillion watts.

Terrawatthour: One trillion kilowatthours.

Ton: A unit of weight equal to 2,000 pounds.

Turbine: A machine for generating rotary m echanical

power from the energy of a stream of fluid (such as water,

steam, or hot gas). Turbines convert the kinetic energy of

fluids to mechanical energy through the principles of

impulse and reaction, or a mixture of the two.

Two

- Party Wheeling: An arra ngement between two

entities in which one entity agrees to transmit electricity

owned by the other.

Ultimate Consumer: A consumer that purchases

electricity for its own use and not for resale.

Useful Thermal Output: The thermal energy made

available in a

combined heat or power system for use in

any industrial or commercial process, heating or cooling

application, or delivered to other end users, i.e., total

thermal energy made available for processes and

applications other than electrical generation.

Wast e Coal: As a fuel for electric power generation,

waste coal includes anthracite refuse or mine waste, waste

from anthracite preparation plants, and coal recovered

from previously mined sites.
