Inventory of Power Plants in the United States 1985 

Energy Information Administration 
Preface 

P.6 

The Inventory of Power Plants in the United Statesis 

published annually by the Electric Power Division; 

Office of Coal, Nuclear, Electric and Alternate Fuels; 

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

Inventory of Power Plants in the United States presents 

information about electric generating units operated 

by or planned to be operated by electric utilities in the 

United States (the 50 States and the District of Columbia) and Puerto Rico. Data summarized in this report 

are useful to a wide audience including Congress, Federal and State agencies, the electric utility industry, and 

the general public. The data presented in this report 

were assembled and published by the EIA, to fulfill 

its data collection and dissemination responsibilities as 

specified in the Federal Energy Administration Act of 

1974 (P.L. 93-275) as amended. 

This 1985 Inventory of Power Plants in the United 

States is the first comprehensive edition of this publication since the 1981 comprehensive edition. It presents 

statistics about electric generating units in operation 

by electric utilities, and a 10-year outlook of future 

generating unit additions by electric utilities, as of calendar year ended 1985. Beginning with this comprehensive edition, the EIA returns to publishing the comprehensive edition annually, as opposed to publishing 

it every 5 years. Beginning with this 1985 annual issue 

of Inventory of Power Plants in the United States, an 

electric generating unit is considered to be in operation 

if the unit is operable, as opposed to the previous criterion of commercial operation which has been used for 

predecessor publications. A unit is defined to be operable when it is available to provide power to the grid. 

A nuclear unit is operable when it receives its full 

power amendment to its operating license from the 

Nuclear Regulatory Commission. Likewise, starting 

with this issue, initial year of operation is the year the 

unit became operable, as opposed to the previous definition , the year the unit started commercial operation. 

Therefore, the units presented in this publication as 

having started operation in 1985 (added capacity) are 

those units that initially became available to provide 

power to the grid in 1985. These units may or may not 

have been declared in commercial operation in 1985. 

Electric generating units that began commercial operation in 1985, but were initially available to provide 

power to the grid in 1984, are not presented as part of 

the added capacity in 1985. A list of electric generating 

units that began commercial operation in 1985 is presented in the Electric Power Annual. 

Also, beginning with the 1985 annual issue of Inventory 

of Power Plants in the United States, discussion involving electrical generating unit capacity values will be 

based on net summer capability, as opposed to installed 

generator nameplate capacity. The chapter entitled 

Introduction discusses the difference between generator nameplate capacity and net capability. Net summer 

capability is the steady hourly output which generating 

equipment is expected to supply to system load, exclusive of auxiliary power, as demonstrated by test at the 

time of summer peak demand. Although the discussion 

contained herein is based on net summer capability, 

tables in this publication will continue to contain values for installed generator nameplate capacity and net 

winter capability as well as net summer capability. 

The Inventory of Power Plants in the United States is 

organized in the following chapters. 

1. Introduction 

2. Electric Generating Units 

3. Projected Units 

The Introduction contains aggregate capacity statistics 

at the national and various regional levels for operable 

electric generating units and planned electric generating unit additions. Aggregate capacity data at the national level are presented by primary energy source 

and by prime mover. Aggregate capacity data at the 

various regional levels are presented by primary energy source. The chapter, Electric Generating Units, 

contains detailed data about each operable electric 

generating unit and each electric generating unit that 

was retired from service during 1985. Additionally, it 

contains a summary of electric generating unit capacity 

additions and retirements during 1985, by energy 

source. Projected Units contains detailed data about 

each electric generating unit scheduled by electric utilities to start operation between 1986 and 1995. Additionally, it contains a summary of electric generating 

unit retirements, by energy source, projected to occur 

from 1986 through 1995. 

The Introduction does not include data related to Puerto Rico; the aggregate statistics presented in this chapter include data for the 50 States and the District of 

Columbia. Likewise, any discussion of data presented 

Inventory of Power Plants in the United States 1985 

Energy Information Administration 
P.7. 

herein refers to the 50 States and the District ot Columbia. However, detailed generator level data for power 

plants operated by electric utilities in Puerto Rico are 

contained in the applicable chapters, under the heading, Puerto Rico. 

The detailed data about electric generating units include the name of the electric utility operating the unit, 

the location of the unit, its primary and alternate energy sources, its installed generator nameplate capacity, 

net summer capability, and net winter capability. Data 

in these chapters are organized alphabetically by State 

and electric utility. 

Updates that have been made during the past year and 

are reflected in this publication are as follows: 1) Updates that reflect construction or modification within 

power plants or changes in power plant operations 

during the reporting year. These changes within power 

plants include the installation of new generators; the 

retirement of existing generators; the use of a primary 

energy source different from that which has been reported in the past (for dual-fired units); and the modification of generators, such as the rewinding of stators 

or the retrofitting of associated generator equipment. 

2) Corrections to previously reported data that were 

incorrect. 3) Deletion of respondents from the universe 

of the EIA-860, whose operations do not meet the 

requirements for that universe. 4) Deletion or addition 

of capacity when electric utilities' sales and acquisitions are made to and from companies whose operations do not conform to the reporting requirements of 

Form EIA-860. 

A summary of the capacity changes attributed to each 

of these specific categories of updates is not available. 

A tracking system which allows capacity changes to 

be categorized and presented in conjunction with annual summary data currently presented in this publication has been proposed for future editions. 

Sources of Data 

Data published in the Inventory of Power Plants in the 

United States 1985 were compiled from Form 

EIA-860, "Annual Electric Generator Report," filed 

annually with the EIA by electric utilities. For a description of the data submitted on this form, see Section 

1.1 of the Technical Notes, Appendix A. 

Adjustments to Collected Data 

Data on generator nameplate capacity and net summer 

and net winter capability for electric generating units 

in commercial operation are published as reported on 

Form EIA-860, "Annual Electric Generator Report." 

Estimates of net summer capability and net winter 

capability were made for operating nonnuclear electric 

generating units with no reported capability and for 

all electric generating units that are under construction 

or in the planning stage. These estimates were developed using a statistical relationship that exists between 

the capability (summer and winter) and installed generator nameplate capacity for units that were in operation 

as of the end of 1984. For nuclear units, the (net) design 

electrical rating was used instead of installed generator 

nameplate capacity in developing the statistical relationship. These relationships were also used to estimate 

the capabilities of new units in operation that have not 

undergone a capability test. 

Where the actual year in which an electric generating 

unit was first available to provide power to the grid 

is not known, certain assumptions were made to estimate the initial year of operation, using the date of 

initial commercial operation. These assumptions refer 

to the length of the testing period for the unit just prior 

to the time the unit begins commercial operation. 

Based on the following assumptions, year of initial 

operation was determined. Gas-turbine and internal 

combustion units are available to provide power to the 

grid one month prior to the date they are declared in 

commercial operation; a hydroelectric unit is available 

3 months prior to commercial operation. For 

nonnuclear steam-electric generating units, a unit that 

started commercial operation prior to 1961 was available to provide power to the grid one month prior to 

commercial operation; a unit that started commercial 

operation between 1961 and 1970 was available to 

provide power to the grid 2 months prior to commercial operation; a unit that started commercial operation 

between 1971 and 1979 was available to provide power 

to the grid 3 months prior to commercial operation; 

a unit that started commercial operation after 1979 was 

available 4 months prior to commercial operation. (Initial year of operation for nuclear electric generating 

units is reported data.)

1. Introduction 

Beginning with the 1985 issue of Inventory of Power 

Plants in the United States, discussion involving electrical generating unit capacity values is based on net 

summer capability, as opposed to installed generator 

nameplate capacity. The statistics cited in the text below and in all other text in this publication are based 

on net summer capability. 

Generator nameplate capacity is determined by the 

generator manufacturer under specified test conditions 

normally conducted at the factory. The manufacturer 

stamps the achieved test capacity on the metal nameplate attached to the generator. Generator capability, 

on the other hand, is determined by the utility operating the generator, and is based on historical performance of the generator and associated equipment. Generator nameplate capacity and generator capability 

generally differ from each other because the test conditions used to establish the nameplate rating differ from 

those normally encountered in daily power plant operations. Different steam working pressures and temperatures, capacity limitations of boilers, cooling systems, 

turbines, and environmental control equipment, different hydrogen pressures used to cool the generator, and 

reliability considerations cause discrepancies between 

nameplate and operating capacity. 

Generator nameplate capacity reflects the capability 

of the generator to generate electricity without regard 

to electrical loads from associated equipment such as 

boilers, particulate collectors, flue gas desulfurization 

units and plant lighting. Generator nameplate is therefore the gross capacity of the equipment. Net capability 

refers to the ability of the generator to generate electric 

power, taking into consideration the electrical requirements of associated plant equipment. For example, the 

electricity to run flue gas desulfurization equipment 

comes from electricity generated at the plant. Net, 

therefore, refers to the electricity available to be sent 

off-site (for consumption) after plant electrical loads 

have been satisfied. 

Net summer and net winter capability (the capacity of 

the generator that is generally achievable during the 

summer and winter months, respectively, after plant 

electrical requirements have been satisfied) is determined by the utility operating the generator on the 

basis of historical performance of the generator and 

associated equipment. The summer and winter figures 

are usually not the same because of the differences in 

ambient temperatures during each season. Power plant 

cooling capacity, an essential part of electric power 

generation, decreases as air and water temperatures 

increase. Summer capability is therefore generally 

lower than winter capability because high summer 

temperatures can strain power plant cooling capacity 

to the extent that maximum electric power generation 

cannot be achieved. 

The net summer generating capability of electric generating units in operation by the Nation's electric utilities, as of year-end 1985, totaled 656,118 megawatts. 

Coal (including lignite) was the energy source that 

accounted for the greatest share of U.S. installed generating capability. The mix of capacity, as of year-end 

1985 was as follows: coal, 43.6 percent; petroleum, 11.7 

percent; gas, 18.3 percent; water, 13.5 percent; nuclear, 

12.2 percent; and other, 0.6 percent. Statistics on yearend capacity, by energy source, as shown in Table 1, 

reflect the significant shift from petroleum-fired capacity to gas-fired capacity that has occurred in dual-fired 

units over the past several years. 

During 1985, electric utilities added 19,265 megawatts 

to operable net summer generating capability. The mix 

of capacity that commenced operation in 1985 is as 

follows: coal, 31.0 percent; petroleum, 0.4 percent; 

nuclear, 51.2 percent; gas, 0.1 percent; water, 15.8 percent; and geothermal, 1.5 percent. (Table 12.) 

During 1985, electric utilities retired from service 2,472 

megawatts of net summer generating capability. The 

mix of capacity that was retired from service in 1985 

is as follows: gas, 42.9 percent; coal, 21.4 percent; petroleum, 23.0 percent; nuclear, 10.5 percent; water, 2.0 

percent; and wind, 0.2 percent. (Table 12.) 

The Nation's electric utilities are planning a construction program that includes 67,609 megawatts of new 

net summer capability that will begin operation by 

1995. The 67,609 megawatts planned for initial operation between 1986 and 1995 is substantially less than 

the total planned additions as of year-end 1984. This 

reduction primarily reflects the cutbacks in plans for 

new coal and nuclear-fired capacity. The mix of capacity scheduled to start operation between 1986 and 1995 

is as follows: coal, 45.0 percent; nuclear, 42.9 percent; 

petroleum, 1.5 percent; water, 5.6 percent; gas, 3.9 

percent; and other sources (geothermal, refuse, solar, 

waste heat, wind, and wood), 1.1 percent. (Table 1.) 

Inventory of Power Plants in the United States 1985 

Ene--gy Information Administration 
P.13 

Electric utilities have scheduled 12,638 megawatts in 

372 generating units for retirement over the next decade. Over 80 percent of this projected capacity retirement is in either petroleum-fired or gas-fired units. 

(Tables 17 through 20.) 

Summary data on operable capacity and planned capacity additions are contained in Tables 1 through 11 

of this chapter. Summary data on planned capacity' 

retirements are contained in Tables 17 through 20 of 

the chapter, Projected Units. 

Coal-fired capability accounted for the greatest share of U.S. installed generating capability in 1985.

Energy Information Administration 
2. Electric Generating Units 

P.21 

There were 10,475 electric generating units in operation by the Nation's electric utilities, as of year-end 

1985. This total is comprised of all those units available 

to produce electricity to the power grid, including 

those units in an inactive reserve status (not normally 

used, but available for service), those in deactivated 

shutdown status (out of service for 365 days or longer), 

and those that had started generating electricity to the 

power grid by the end of year, although they ma- have 

still been in a testing phase. Detailed data ab* each 

of these electric generating units are container! ;r. Table 

15. These 10,475 units had a total capability : >, 118 

megawatts. Of the 656,118 megawatts of c; .rable capacity, 285,794 megawatts are in 1,283 coal-fired units; 

76,842 megawatts are in 3,454 petroleum-fired units; 

120,225 megawatts are in 2,104 gas-fired units; 88,863 

megawatts are in 3,426 hydroelectric units; and 80,277 

megawatts are in 96 nuclear-powered units. There 

were 112 electric generating units with a total capability of 4,117 megawatts that used other primary energy 

sources to produce electricity. These 112 electric generating units include 25 geothermal units, 21 windmills, 

2 solar units (Sacramento Municipal Utility District's 

one-megawatt Solar 1 and Southern California Edison 

Company's 10-megawatt Solar 1), 41 units that used 

waste heat, 7 units fueled by refuse or other nonwood 

waste (4 refuse-fueled steam units and 3 methane internal combustion units built above a solid-waste landfill), 

12 steam units fueled by wood, 1 steam unit fueled by 

a coal-oil mixture (Florida Power Corporation's P. L. 

Bartow 1), 2 multifueled (two or more fuels burned 

simultaneously, but not as a mixture) steam units, and 

1 unit that uses steam. 

The 3,454 petroleum-fired electric generating units include 386 steam units with a total capacity of 51,465 

megawatts and 3,068 gas-turbine and internal combustion units with a total net generating capability of 

25,377 megawatts. (Table 2.) 

The 2,104 gas-fired electric generating units include 

784 steam units with a total net generating capability 

of 97,133 megawatts and 1,320 gas-turbine and internal 

combustion units with a total net generating capability 

°f 23,092 megawatts. (Table 2.) 

During 1985, electric utilities added 19,265 megawatts 

to their net summer generating capability. Of the 

'9,265 megawatts of added capacity, 5,975 megawatts 

are in 12 coal-fired units; 72 megawatts are in 35 

petroleum-fired units; 22 megawatts are in 7 gas-fired 

units; 3,044 megawatts are in 33 hydroelectric units; 

and 9,864 megawatts are in 9 nuclear-powered units. 

The remaining 287 megawatts of added capacity were 

in 3 geothermal units. 

Except for the one petroleum-fired gas-turbine unit 

operated by Alaska Electric Generation & Transmission Coop (Soldotna GT1), all of the petroleum-fired 

capacity that came on line in 1985 is in internal combustion (diesel) units and all of the gas-fired capacity is in 

gas-turbine units. Included in the 33 hydroelectric generating units which came on line in 1985 is Virginia 

Electric and Power Company's Bath County pumped 

storage plant. All six 350-megawatt units of this plant 

started operation during 1985, making it the Nation's 

largest pure pumped-storage hydroelectric project. 

Two hundred eighty-seven megawatts of geothermal 

capacity were brought on line in 1985. This capacity 

includes Pacific Gas and Electric's The Geysers 16 and 

20 (113 megawatts each), and San Diego Gas and Electric Company's Heber 1 (61.3 megawatts). (Table 13.) 

Table 12 of this chapter summarizes by primary energy 

source, capacity additions and retirements in 1985. Tables 13 and 14 list by State the individual units associated with these additions and retirements. 

During 1985, electric utilities retired from service 135 

units totaling 2,472 megawatts of net summer capability. Of the 2,472 megawatts of retired capacity, 530 

megawatts are in 30 coal-fired units; 569 megawatts are 

in 47 petroleum-fired units; 1,060 megawatts are in 43 

gas-fired units; 50 megawatts are in 11 hydroelectric 

units; and 260 megawatts are in 2 nuclear-powered 

units. The remaining capacity retired from service in 

1985 was in wind units. Those nuclear units retired 

were Pacific Gas & Electric Company's Humboldt 

Bay and Commonwealth Edison Company's Dresden 

1. These nuclear units had been shut down for several 

years leading up to their retirement. Modification requirements for these reactors were such that it was 

uneconomical to bring them back on line. 

Among the various energy sources, the greatest number of units retired was petroleum-fired. However, the 

greatest amount of capacity retired was in gas-fired 

units.

Appendix A 

Technical Notes 

1. Sources of Data 

The Office of Coal, Nuclear, Electric and Alternate 

Fuels (CNEAF) is responsible for routine data improvement and quality assurance activities. All operations of CNEAF are done in accordance with formal 

standards established by the Energy Information Administration (EIA). These standards are the measuring 

rod necessary for quality statistics. Data improvement 

efforts include verification of data-keyed input by automatic computerized methods, editing by subject matter 

specialists, and follow-up on nonrespondents. Generally, completed forms received by the CNEAF are sorted, screened for completeness of reported information, 

and keyed onto computer tapes for storage and transfer 

to data b^ es on random access storage devices for 

computer processing. The information coded on the 

computer tapes is spot-checked against the forms by 

hand to certify accuracy of the tapes. To insure the 

quality standards established by EIA, the v'Tice has 

designed and implemented algorithms using tne past 

history of data values in the data base to check data 

input for errors. This automatically reduces the possibility of erroneous entries in the data bases over, time 

as the historical data become more refined. Data values 

rejected by the algorithms are checked with 

respondents by telephone to correct the problems. 

Computerized data files of respondents are checked to 

identify those who fail to respond to the survey. By 

law, nonrespondents may be fined or otherwise penalized for not filing an EIA data form as prescribed in 

the instructions. Before invoking the law, the EIA tries 

to obtain the required information by encouraging cooperation of nonrespondents. The CNEAF supports 

the quality assurance efforts of the data collectors by 

providing advisory reviews of information requirements, and of proposed designs for new and revised 

data collection forms and systems. The actual performance of working data collection systems is validated 

once they are implemented. Following is a synopsis of 

the data collection system used to prepare Inventory 

of Power Plants in the United States 1985. 

/. / Form EIA-860 • 

Generator Report 

Annua/ Electric 

Summary Statement of the Form 

EIA-860 Primary Purpose 

The Energy Information Administration provides for 

the annual collection of data on electric utilities' existing power plants and their 10-year plans for constructing new plants, and generating unit additions, modifications, and retirements in existing plants. Data on Form 

EIA-860 are collected from all electric utilities in the 

United States and Puerto Rico that operate power 

plants or plan to operate a power plant within 10 years 

of the reporting year. 

Instrument and Design History 

The Form EIA-860 was implemented in January 1985 

to collect data as of year-end 1984. The Federal Energy 

Administration Act of 1974 (P. L. 93-275) defines the 

legislative authority to collect these data. 

Data Processing 

~Da.tr — Form EIA-860 are submitted through mail by 

apr .nately 900 respondents. The forms are mailed 

to tn*_- respondents in December to collect data as of 

the end of the preceding calendar year. The completed 

forms are due at the EIA on February 15. Data for each 

respondent are preprinted from the applicable data 

base. Respondents are instructed to verify all preprinted data and to supply missing data. 

Processing of the data on Form EIA-860 is the responsibility of the Electric Power Division's Data Systems 

Branch of the Office of Coal, Nuclear, Electric and 

Alternate Fuels. The system used to process data reported on Form EIA-860 was designed by this office. 

The data are manually edited before being reduced for 

automatic data processing. Computer programs containing additional edit checks are run. Respondents are 

telephoned to obtain correction or clarification of reported data and to obtain missing data, as a result of 

the manual and automatic editing process.
