Generation. Electricity markets in 2009 were keenly affected by economic and environmental developments. Electricity generation was down 4.1 percent, reaching its lowest level since 2003; this was the largest decline in 6 decades 1 

## and follows a 0.9-percent decline in 2008. The drop in power demand reflects a 2.6-percent decline in economic activity (GDP) during 2009. 2 

## Summer temperatures during 2009 were relatively mild, resulting in a 1.1 percent decline in residential electricity sales between 2008 and 2009. A 9.1-percent decline in industrial demand for electricity, which fell to the lowest level since 1987, accounted for most of the decline in overall electricity consumption. The drop in industrial electricity demand reflected the 9.3- percent drop in industrial output, as measured by the Federal Reserve Bank’s index of industrial production. 3


## Emissions. Environmental developments played an important role in electricity markets in 2009.

The policy debate over greenhouse gas legislation continued throughout 2009. Electric power plant investment and operation decisions made during 2009 may have been affected byexpectations that some form of future cap on carbon dioxide (CO 2

## ) loomed on the horizon.

CO 2 

## , nitrogen oxides (NO x 

## ,) and sulfur dioxide (SO 2

## ) emissions posted the largest declines on record. 4 

## Total CO 2 

## emissions were 8.6-percent lower in 2009. Emissions from coal-fired plants fell 11.0 percent, largely attributable to a 10.3-percent decline in coal consumption.

1 The U.S. Energy Information Administration’s historic electricity generation data goes back to 1949. 2 U.S. Department of Commerce Bureau of Economic Analysis, News Release: Gross Domestic Product: Second Quarter 2010 (Third Estimate) , Table 1. 3 U.S. Federal Reserve Bank, Industrial Production and Capacity Utilization , (Table 11 ). 4The U.S. Energy Information Administration has been estimating CO 2 , NO X, and SO 2 emissions since 1989. 

## NO x 

## and SO 2 

## emissions from electric power plants declined 28.1 and 23.8 percent,respectively (Table 3.9) in 2009. For coalfired generation, the declines in NO x 

## and SO 2

## emissions were even greater, at 34.0 percent and 24.7 percent, respectively.

Fuel costs. The price of natural gas delivered to electric power plants fell in 2009 to roughly half the 2008 level. In 2009, annual average natural gas wellhead prices reac hed their lowest level in 7 years. Increased supply due to the availability of shale gas, coupled with mild winter temperatures and higher production, and storage levels, and significant expansions of pipelines capacity also worked to put downward pressure on natural gas prices. 5 

## At the same time, the cost of coal rose 6.8 percent (Table 3.8), largely due to long-term contracts signed prior to the recent recession. 6, 7 

## Between 2000 and 2009, coal prices to electric power plants rose 84 percent. Coal-to-gas switching. The increase in delivered coal prices and the decrease in delivered natural gas prices, combined with surplus capacity at highly-efficient gas-fired combined-cycle plants resulted in coal-to-gas fuel switching This occurred particularly in the Southeast (Alabama, Arkansas, Florida, Georgia, Mississippi, and South Carolina) and also Pennsylvania. Nationwide, coal-fired electric power generation declined 11.6 percent from 2008 to 2009, bringing coal’s share of the electricity power output to 44.5 percent, the lowest level since 1978. Coal consumption at U.S. power plants paralleled the decline in generation, dropping 10.3 percent from 2008. In sharp contrast, natural gas-fired generation increased 4.3 percent in 2009, despite the 4.1- percent decline in overall electric generation. The natural gas share of generation increased to 23.3 percent—the highest level since 1970. Electricity’s share of the total U.S. natural gas consumption has also risen rapidly, growing from 17 percent in 1996 to over 30 percent in 2009. 8

5 U.S. Energy Information Administration, Natural Gas Year-inReview, 2009 6 U.S. Energy Information Administration, U.S. Coal Supply and Demand: 2009 ”Coal Prices”, p. 12 7 The Southern Company (a large consumer of coal for electricity production), reported: “While coal prices reached unprecedented high levels in 2008, the recessionary economy pushed prices downward in 2009. However, the lower prices did not fully offset the higher priced coal already in inventory and under long-term contract.” Southern Company 2009 10-K, p. II-16.

## U.S. Energy Information Administration/Electric Power Annual 2009 2 

## Wind development. Wind power has been the fastest-growing source of new electric power generation for several years. In 2009, generation from wind power increased 33.5 percent over 2008, bringing the share of total generation to 1.9 percent. This followed year-over-year generation gains of 60.7 percent in 2008, 29.6 percent in 2007, and 49.3 percent in 2006 (Table ES.1). Wind capacity in 2009 totaled 34,296 megawatts (MW), as compared to 24,651 MW in 2008. In 2009 (and 2010), wind generators were eligible for Federal production and investment tax credits or a cash grant in lieu of those tax credits. 9 

## Since passage of the 2005 Energy Policy Act (EPACT2005), interest-free financing via Clean Renewable Energy Bonds (CREBs) has been available to government entities investing in wind. Section 9006, under Title IX of the 2002 and 2008 Farm Bills, also contains grant and loan guarantee provisions for wind projects for farmers, ranchers, and other rural businesses. Renewable generation is fostered by both Federal incentives and State renewable portfolio standards. As of October 2010, 29 States, the District of Columbia, and Puerto Rico have legislated renewable energy portfolio standards, and 7 more States have adopted renewable portfolio goals. 10



# .#'!# Net generation of electric power fell 4.1 percent in 2009, to 3,950 million megawatthours (MWh) from 4,119 million MWh in 2008 (Figure ES1). This is the largest decline in electricity generation in at least 60 years. Electricity generation also declined 0.9 percent in 2008. The years 2008 and 2009 represent only the third and fourth instances that generation has dropped year over year since 1949 (the first two occurrences were during recessions in 1982 and 2001).

8U.S. Energy Information Administration, Annual Energy Review, 2009, Table 6.5.

9 The grant program arose out of Section 1603 of the American Economic Recovery and Reinvestment Act of 2009 (ARRA) and was intended to allow investors who could not take advantage of tax credits to fund these projects with an equivalent government grants. This program expires December 31, 2010.

. 

## Additionally, this is the first time over the last 6 decades that generation has declined in two consecutive years. Coal, natural gas, and nuclear generation accounted for 88.0 percent of total net generation in 2009, and between 85 and 90 percent during the period 1997 through 2009. However, the relative contribution of these energy sources has been shifting; natural gas generation has seen the fastest growth in recent years. /!,$0 1 2101&'!&()#$'% '.#'!#

## Coal. Coal-fired electric generation declined 11.6 percent between 2008 and 2009. With this decline, coal’s share of electricity generation reached its lowest level since 1978: 44.5 percent of electricity generation in 2009, down from 48.2 percent in 2008. Several factors have worked to erode the advantage that coal-fired generation has historically derived from its lower fuel costs. These factors include lower natural gas prices and higher coal prices; surplus capacity at efficient natural gas plants, and the cost of compliance with current environmental regulations.
Production at the Nation’s coal mines in 2009 reflected the weakened state of coal demand for

## U.S. Energy Information Administration/Electric Power Annual 2009 3 

## electricity generation. Appalachian coal production fell 13.0 percent in 2009 from the previous year. Even Western (Powder River Basin) coal production, which has a significant price advantage, showed an 8.1-percent decline in 2009. 11 

## Natural gas-fired power generation increased by 4.3 percent in 2009, raising natural gas’s share of the electricity market to 23.3 percent— its highest share since 1970. Natural gas’s share of the electricity market has been greater than the nuclear share since 2006. New capacity, as well as the increased utilization of existing generators (see Table 5.2 on capacity factors), account for the increase in share.

Nuclear power generation accounted for 20.2 percent of the electricity generated in 2009, a 0.9-percent decrease from the prior year. The decline in nuclear gene ration in 2009 is the result of scheduled and unscheduled plant outages and derates. Hydroelectric power generation fluctuates perennially with precipitation levels and snow accumulation. Overall, generation from conventional hydro plants (exclusive of pumped storage) increased 7.3 percent from 2008 to 2009 (Table ES.1). The western States were still suffering from a prolonged drought during 2009. The Bonneville Power Administration, which is the largest producer of hydroelectric power in the west, reported reduced runoff for the January through July 2009 period as compared to the same period in 2008. 12 

## In contrast, many eastern States experienced record rainfall: Alabama, Georgia, Kentucky, North Carolina, and Tennessee all reported substantial gains in hydro generation in 2009. The Tennessee Valley Authority cited better water conditions, resulting in a 71-percent increase in hydropower during 2009. 13


## Renewables . Total non-hydro renewable generation increased 14.0 percent in 2009, following a 19.9-percent increase in 2008. The fastest-growing component was wind power (33.5-percent increase). Solar generation

Melting snow creates much of BPA’s runoff. Snowpack in the mountains accumulates from December to February (approximately), and significant runoff, and therefore peak hydro production, occurs March through July (approximately). 13 Tennessee Valley Authority, 2009 Annual Report (10-K) , p.12. 

## increased 3.1 percent. Since 1998, generation from non-hydro renewables has increased 86.6 percent. In 2009, renewable generation made up 10.6 percent of total generatio n. The largest three contributors were hydro (6.9 percent), wind (1.9 percent), followed by wood and wood-derived fuels (0.9 percent). Discounting the hydro portion, renewable generation made up 3.6 percent of total generation.
Petroleum’s contribution to U.S. net electricity generation peaked in 1973 at 17 percent, but has fallen steadily since to almost insignificant levels. Petroleum’s share of power output fell below one percent in 2009, reflecting a 15.8- percent decrease in petroleum-fired power generation between 2008 and 2009.
Nuclear and fossil capacity factors . The capacity factor is a measure of how consistently a generator is producing power: it represents the ratio of actual generation during a time period (typically a year) to the maximum possible generation assuming continuous full-load output. Baseload plants, which have high utilization rates due primarily to low variable operating costs, typically operate at capacity factors of 70 percent or higher. Intermediate plants, which have higher variable operating costs, typically vary their output during the day to meet changes in load. The most expensive peaking plants may operate rarely and only to meet the highest peaks, usually in the summer or winter. Due to decreased demand for electricity, the average capacity factor for many fuels fell in 2009 (Table 5.2). Nuclear power plants (which in the United States are universally operated as baseload units because of their very low fuel costs) maintained a high capacity factor (90.3 in 2009). The capacity factor for coal plants, which make up the bulk of U.S. baseload capacity but can also operate in load-following mode, 14 

## dropped sharply (8.4 percentage points) in 2009, from 72.2 percent to 63.8 percent. The vast majority of natural gas capacity in the United States operates as load-following or peaking units. In 2009, coal-to-gas switching increased the usage of combined-cycle natural gas generators; the capacity factor for these units

14Despite representing only three quarters of the capacity of natural gas plants, coal plants account for approximately twice the amount of electricity produced by natural gas plants (Table ES.1)

Total U.S. net summer generating capacity grew by 1.5 percent between 2008 and 2009 to 1,025 gigawatts (GW; Figure ES2). Both in absolute and percentage terms, wind generating capacity showed the strongest gains: the 9,645 MW of wind capacity additions were more than double that of natural gas, which had the second-largest increase in capacity at 3,812 MW. Coal, nuclear, and hydroelectric capacity experienced marginal gains. During 2009, 382 new generators were connected to the grid, 51 fewer than in 2008 (Table 1.11). These new units added 23,144 MW of capacity, 50.1 percent of which were added by independent power producers (IPPs; 11,590 MW), with nearly all of the remainder added by electric utilities (10,939 MW). Wind capacity additions accounted for 63.3 percent of all capacity gains in 2009, increasing the amount of installed wind capacity by 39.1 percent. With 34.3 GW of total capacity, wind now accounts for 3.3 percent of total U.S. capacity, up from less than 3 tenths of a percent 10 years earlier. Four States accounted for 51 percent of total U.S. wind capacity: Texas (9.4 GW), 15 

## Iowa (3.4 GW), California (2.7 GW), and Washington (2.0 GW). Natural gas capacity. In 2009, natural gas capacity increased by 1.0 percent, led by installations in California, Florida and Texas. About 72 percent of all natural gas plant capacity additions during 2009 were highly efficient combined-cycle units. In 2009, combined-cycle units accounted for 50 percent of total natural-gas-fired electricity capacity versus 2 percent of natural gas-fired capacity two decades ago. Coal capacity. Coal-fired electric capacity increased by 0.3 percent between 2008 and2009 to 314,294 MW. A total of 13 new coal15 As of the end of 2009 Texas had 76 wind plants comprising 9.1 percent of overall Texas electricity capacity. In 2005, Texas adopted a RPS which required the state to have 5,880 MW of total renewable capacity in place by 2015, and 10,000 MW by 2025. Texas is very close to meeting the 2025 standard with its wind capacity alone. 

## fired generators came on line in 2009, notably the 682-MW Nebraska City 2 unit (Omaha Public Power District) and the 415-MW Springerville 4 unit (Salt River Project). Both East Kentucky Power Cooperative and Archer Daniels Midland installed generators capable of co-firing coal with biomass.

## Coal retirements in 2009 totaled 529 MW. Further retirements are planned. For example, in December 2009, Progress Energy announced that it planned to retire 11 generators (1,500 MW) at four of its North Carolina coal plants that lacked desulfurization equipment, and replace the lost capacity with natural gas units. Progress Energy’s remaining units are all equipped with scrubbers. 16 

## Solar capacity. Solar power is a rapidly growing source of new capacity, albeit from a relatively small base. Solar power producers added 83 MW of capacity in 2009, a 15.5- percent increase over 2008. California, with 450 MW of existing (utility-scale) solar capacity, accounted for 72.8 percent of total capacity, followed by Nevada, with 14.3 percent of capacity. Two large plants were brought on line in 2009: FPL’s 25 MW DeSoto Solar Energy Plant in Florida, described as the largest photovoltaic solar

## and NRG Energy’s 21-MW facility in Blythe, California, which was constructed in just 3 months. The 20 MW scale of recent solar power plant additions far exceeds the average size of the current fleet of solar units, but is in turn dwarfed by the scale of units in the planning stage. 18 

## For example, by 2013, BrightSource Energy is scheduled to bring on line all three units of its 390-MW Ivanpah concentrated thermal power plant in California. Nuclear uprates.Since 1998, there have been 104 operable units in the United States. 19 

## In 2009, nuclear capacity increased 249 MW, due to a combination of uprates (technical modifications of existing units) and other net capacity adjustments. Through such uprates to existing capacity, rather than new builds, 3.6 GW of nuclear capacity have been added to the system over the past decade (Table 1.1), representing over 3 percent of total U.S. nuclear capacity in 2009. This added capacity is the equivalent of building several new reactors. Prospects for new nuclear reactors. Currently, there is one nuclear power unit under construction, TVA’s 1,150 MW Watts Bar 2, which is scheduled to be in operation in 2012. Initial construction of Watts Bar 2, which began in 1973, was suspended in 1988 and resumed in 2007. TVA may also complete Unit 1 at its Bellefonte site, which would enter operation in the 2018-2019 time frame. TVA suspended construction of Bellefonte in 1988. During 2009, one application was submitted to the Nuclear Regulatory Commission (NRC) for the construction of two nuclear units at FPL’s existing Turkey Point fac ility. This compares to applications for 16 units during 2008 and 8 units in 2007. The NRC also granted an Early Site Permit to Southern Company’s/Georgia Power’s Vogtle nuclear power units 3 and 4 (August, 2009) and preliminary site preparation has begun. 20

## For the period 2010-2014, planned wind additions totaled 11,560 MW, or 16.0 percent of total reported planned additions. Wind plants have a much shorter planning horizon and are built more quickly than fossil fuel-fired plants; only 6.2 percent of the reported new wind capacity additions were planned to occur after 2012.

## Solar additions were expected to add 4,087 MW of capacity by 2014. The planned completion of Watts Bar 2 in 2012 would add 1,122 MW of nuclear capacity. The construction of new coal plants has been discouraged by increasing costs for capital-intensive projects, concerns over possible future CO 2

# &'!&!'%0#(!& In 2009, retail sales of electricity fell to 3,597 billion kilowatthours, a 3.6-percent decline from the prior year and the lowest level of sales since 2004 (Table 7.2). Industrial demand experienced the greatest decline, falling 9.1 percent from 2008, to levels unseen since 1987. The residential and commercial sectors reported declines of 1.1 percent and 2.2 percent, respectively.
Retail sales to industrial customers. The Federal Reserve Bank’s index of industrial production fell 9.2 percent in 2009, driven by 41 and 42 percent decreases in the automobile and iron and steel components, respectively. 22 

## In the East North Central Census Division, which contains some of the Nation’s most industrialized States (Illinois, Indiana, Michigan, Ohio, and Wisconsin), overall electricity demand declined 6.9 percent (Figure ES4), led by a 12.3- percent decline in industrial demand. The East South Central States (Alabama, Kentucky, Mississippi, and Tennessee) saw the next largest decline at 6.8 percent.

Weather and Retail Sales to Residential Customers. Year-over-year (i.e., short term) changes in residential electricity sales largely reflect changes in the weather. Summer temperatures during 2009 were relatively mild in the contiguous states. 23 

## This dampened air conditioning demand; for the June through August summer period, residential electricity sales declined 3.3 percent between 2008 and 2009.

## Prices . Overall retail electricity prices rose 0.9 percent between 2008 and 2009 (from 9.74 cents to 9.83 cents per kWh). The overall 25.8-percent decline in fossil fuel prices as delivered to electric plants had little immediate impact on electric power prices to the end user; the lag in changes between fuel prices and power prices can be a year or two, as changes in retail electricity rates are dependent on each State’s utility regulatory review process.

Wholesale Markets . Wholesale power purchases in 2009 totaled 5,029 million MWh. 24 

## This represents a decrease of 10.4 percent between 2008 and 2009, following an increase of 3.7 percent from 2007 to 2008 (Table 6.1) and a peak in 2002 at 8,755 million MWh. Electric utilities and energy-only providers (power marketers) each account for roughly half of wholesale purchases. The power marketers’ share of the wholesale market dropped from 69.1 percent in 2002 to 51.0 percent in 2009, as a consequence of the financial failure of many marketers and contraction of trade following the collapse of Enron. Elect ric utilities’ wholesale purchases have generally remained stable over the last decade, but in a shrinking market their market share has risen from 29.9 percent in 2002 to 47.0 percent in 2009.

24 A single “block” of electricity can be sold multiple times, with each purchase appearing in the data reported to EIA. Consequently, total wholesale purchases exceed total su pply of electricity (3,950 million MWh in 2009).

## U.S. Energy Information Administration/Electric Power Annual 2009 7 

## Electricity sales for re sale (wholesale power sales) fell similarly in 2009, down 10.8 percent from 2008 to 5,065 million MWh. Energy-only providers made up 44.2 percent of the market in 2009. Electric utilities compri sed 29.5 percent of the market in 2009, IPPs 25.6 percent, and combined heat and power plants less than one percent.

International trade. The U.S. buys from and sells electricity to Canada and, to a much smaller degree, Mexico. Although the U.S. imported slightly less than 1 percent of its electricity consumption in 2009, Canadian exports account for roughly 8 percent of Canada’s production of electricity (Table 6.3). 25 

## Canada is the second largest exporter of electricity in the world, primarily generated by hydroelectric plants in Quebec, Ontario, and British Columbia. 26 

## Canadian and U.S. electricity markets are highly integrated with multiple transmission lines crossing the international border. Electricity trade with Mexico is much smaller. Net purchases from Mexico in 2009 constituted 0.01 percent of total U.S. supply.

Stocks at Electric Power Plants. End-of-year coal stocks rose 17.3 percent between 2008 and 2009 to reach their highest levels in at least 60 years. At 189 million tons, coal stocks have almost doubled since 2005 (Table 3.4), probably due to the sharp decline in coal-fired generation combined with limited flexibility in coal supply contracts to reduce deliveries. 27

## In some cases, this involuntary inventory accumulation has prompted utilities to attempt to renegotiate their coal contracts or to petition their PUCs for ameliorative actions. 28

Most of this decline relates to natural gas prices; in 2009 natural gas prices fell to about half their 2008 levels (Figure ES5). Annual average costs of natural gas to the electric power industry peaked in 2008 at $9.02 per million Btu—the highest nominal dollar level in at least two decades—before falling to $4.74 per MMBtu in 2009. The average cost of coal actually rose between 2008 and 2009 from $2.07 to $2.21 per MMBtu, due to the prevalence of long-term contracts and the relatively small role of the coal spot market.

Data prior to 2004 includes small quantities of waste oil. 15 For 2002 through 2007, includes data from the Form EIA-423 for independent power producers, and commercial and industrial power-producing facilities. Beginning in 2008, data are collected on the Form EIA-923 for utilities, independent power producers, and commercial and industrial power-producing facilities. Receipts, cost, and quality data are collected from plants above a 50 MW threshold, and imputed for plants between 1 and 50 MW. Therefore, there may be a notable increase in fuel receipts beginning with 2008 data. Receipts of coal include imported coal. 16 Natural gas, including a small amount of supplemental gaseous fuels that cannot be identified separately. 17 Data presented are reflective of large utilities.

1 Includes anthracite, bituminous, subbituminous and lignite coal. Waste and synthetic coal were included starting in 2002. 2 Distillate fuel oil (all diesel and No. 1, No. 2, and No. 4 fuel oils), residual fuel oil (No. 5 and No. 6 fuel oils and bunker C fuel oil), jet fuel, kerosene, petroleum coke (converted to liquid petroleum, see Technical Notes for conversion methodology), and waste oil. 3 Blast furnace gas, propane gas, and other manuf actured and waste gases derived from fossil fuels. 4 Electric utility CHP plants are included in Electricity Generators, Electric Utilities. 5 Small number of electricity-only, non-Combined Heat and Power plants may be included. * = Value is less than half of the smallest unit of measure. Notes: • See Glossary reference for definitions • A new method of allocating fuel consumption between electric power generation and useful thermal output (UTO) was implemented with publication of the preliminary 2008 data, and retroactively applied to 2004-2007 data. The new methodology evenly distributes a combined heat and power (CHP) plant`s losses between the two output products (electric power and UTO). In the historic al data, UTO was consistently as sumed to be 80 percent efficient and all other losses at the plant were allocated to electric power. This change results in the fuel for electric power to be lower while the fuel for UTO is higher than the prior set of d ata as both are given the same efficiency. This results in the appearance of an increase in efficiency of production of electric power after 2003.

Natural gas values f or 2001 forward do not include blast furnace gas or other gas. 4 Beginning in 2006, receipts of petroleum liquids went down substantially, while the receipts of petroleum coke remained the nearly the same. The Average Sulfur Percent by Weight is higher beginning in 2006 as a result the greater influence by petroleum coke receipts, which has higher sulfur content, than the petroleum liquid receipts. 5Beginning in 2002, data from the historical Form EIA-423 for independent power producers and combined heat and power producersare included in this table. Prior to 2002, these data were not collected; the data for 2001 and previous years include only data collected from electric utilities via the historical FERC Form 423. Notes: • Mcf equals 1,000 cubic feet. Totals may not equal sum of components because of independent rounding. • Beginning in 20 08 with the Form EIA-923, receipts, cost, and quality data are imputed for plants between 1 and 50 MW, in addition to the data collected from plants above the 50 MW threshold. Ther efore, there may be a notable increase in fuel receipts beginning with 2008 data.

  1 Small number of electricity-only, non-Combined Heat and Power plants may be included. Note: The number of power plants for each energy source is the number of sites for which the respective energy source was repor ted as the most predominant energy source for at least one of its generators. If all generators for a site have the same energy source reported as the most predominant, that site will be counted once under that energy source. However, if the most predominant energy source is not the same for all generators within a site, the site is counted more than once, based on the number of most predominant energy sources for generators at a site. In general, this table translates the number of generators by energy source (Table 1.2) into the number of sites represented by the generators for an energy source. Therefore, the count for Total (All Sectors) is the sum of the counts for each sector by energy source and does not necessarily represent unique sites Source: U.S. Energy Information Administration, Form EIA-860, "Annual Electric Generator Report."

Notes: • Included in the calculation for coal, petroleum, and natural gas average operating heat rate are electric power plantsin the utility and independent power producer sectors. • Combined heat and power plants, and all plants in the commercial and industrial sectors are excluded from the calculations. • The nuclear average heat rate is the weighted average tested heat rate for nuclear units as reported on the Form EIA-860. Technical Note: The average operating heat rate for coal, petroleum and natural gas displayed in Table 5.3 is calculated by dividing the energy consumed (in BTUs) to generate electricity by the kilowatthours of power generated as reported on the Form EIA-923 and its predecessor forms. Included in thecalculation for coal, petroleum and natural gas are utility and independent power producer plants. The calculation excludes combined heat and power plants, industrial plants, and commercial sector plants. The nuclear heat rate is a weighted average (by capacity) of the tested heat rate as reported on the Form EIA-860.

  1 In 2006 the single largest provider of green pricing services in the country discontinued service in two States. More than 297, 600 customers in green pricing programs reverted to standard service tariffs, predominantly in Ohio and Pennsylvania. Notes: • Green Pricing programs allow electricity customers the opportunity to purchase electricity generated from renewable re sources, thereby encouraging renewable energy development. Renewable resources include solar, wind, geothermal, hydroelectric power, and wood. • Net Metering arrangements permit facilities and residences (using a meter that reads inflows and outflows of electricity) to sell any excess power generated over its load requirement back to the distributor to of fset consumption.

# 44#!91 Technical Notes

This appendix describes how the U.S. Energy Information Administration (EIA) collects, estimates, and reports electric power data in the Electric Power Annual. Following is a description of the ongoing data quality efforts and sources of data for the Electric Power Annual

.

# ':$!'%
The Electric Power Annual (EPA) is prepared by the Office of Electricity, Renewables, and Uranium Statistics (ERUS), U.S. Energy Information Administration (EIA), U.S. Department of Energy (DOE). ERUS performs routine reviews of the data collected and the forms on which they are collected. Additionally, to assure that the data are collected from the complete set of respondents, ERUS routinely reviews the frames for each data collection.



# 2#!8!'0$!!# (& Data are entered directly by respondents into the ERUS e-filing system. A small number of hard copy forms are keyed by ERUS. All data are subject to review via edits built into the system, additional quality assurance reports, and review by subject matter experts. Questionable data values are verifiedthrough contacts with respondents. Also, survey nonrespondents are identified and contacted. Initial edit checks of the data are performed through the system by the respondent. Other program edits include both deterministic checks, in which records are 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. Discrepancies found in the data, as a result of these checks, are resolved either by the processing staff or by further information obtained from a telephone call to the respondent company. Those respondents unable to use the electronic reporting method provide the data in hard copy, typically via fax and e-mail. These data are manually entered into the computerized database and are subjected to the same data edits as those that are electronically submitted. Resolution of questionable data is accomplished via telephone or e-mail contact with the respondents. 

# !!!'%8'Annual survey data have nonsampling errors. Nonsampling errors can be attributed to many sources: (1) inability to obtain complete information about all cases (i.e., nonresponse); (2) response errors; (3) definitional difficulties; (4) differences in the interpretation of questions; (5) mistakes in recording or coding the data; and (6) other errors of collection, response, coverage, and estimation 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. Imputation. If the reported values appeared to be in error and the data issue could not be resolved with the respondent, or if the facility was a nonrespondent, a regression methodology was used to impute for the facility. 1,2,3,4,5 

## The regression methodology relies on other data to make estimates for erroneous or missing responses. The basic technique employed is described in the paper “Model-Based Sampling and Inference 2 

## ,” on the EIA website. Additional references can be found on the InterStat website. The basis for the current methodology involves a 'borrowing of strength' technique for small domains. 1,6 ,7


# '!!#(&$ ERUS has adopted the following procedures with respect to the revision of data disseminated in energy data products:

Annual survey data are disseminated either as preliminary or final when first appearing in a data product. Data initially released as preliminary will be so noted in the data

After data are disseminated as final, further revisions will be considered if they make a difference of 1 percent or greater at the national level. Revisions for differences that do not meet the 1 percent or greater threshold will be determined by the Office Director. In either case, the proposed revision will be subject to the EIA revision policy concerning how it affects other EIA products.

The magnitudes of changes due to revisions experienced in the past will be included periodically in the data products, so that the reader can assess the accuracy of the data. The Electric Power Annual presents the most current annual data available to the EIA. The statistics may differ from those published previously in EIA publications due to corrections, revisions, or other adjustments to the data subsequent to its original release. Sensitive Data (Formerly Identified as Data Confidentiality). Most of the data collected on the electric power surveys are not considered business sensitive. However, the data that are classified as sensitive are handled by ERUS consistent with EIA's “Policy on the Disclosure of Individually Identifiable Energy Information in the Possession of the EIA” (45 Federal Register 59812 (1980)). 

# $#!#,#(&#'3-#, 3&$'!# Rounding Rules for Data. To round a number to n digits (decimal places), add one unit to the nth digit if the (n+1) digit is 5 or larger and keep the nth digit unchanged if the (n+1) digit isless than 5. The symbol for a number rounded to zero is (*). Percent Change. The following formula is used to calculate percent differences.

Percent Change =

zero. P Usage of this symbol indicates a preliminary value. The P is defined in endnotes as "P=Preliminary data."
NM Data value is not meaningful when compared to the same value for the previous month or the previous year. This symbol is also used to indicate a data value is not meaningful due to having a high Relative Standard Error (RSE).



# Form EIA-411 The Form EIA-411 is filed as a mandatory report except for Schedule 7 (Transmission Outages) that is still voluntary reported. 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) scheduled capacity transfers; (4) projections of capacity, demand, purchases, sales, and scheduled maintenance; and (5) bulk power system maps. The report presents various North American Electric Reliability Corporation (NERC) regional council aggregate totals for their member electric utilities, with some nonmember information included. The eight NERC councils submit data for the Form EIA-411 to NERC. A joint response, through the NERC Headquarters, is filed annually on July 15. The forms are compiled from data furnished by electricity generators and electric utilities (members, associates, and nonmembers) within the council areas. 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, 383-3, and 383- 4. The Department of Energy, established in October 1977, assumed the responsibility for this activity. Until 2008, this form was 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 transferred to EIA for the reporting year 1996. Issues within Historical Data Series The Florida Reliability Coordinating Council (FRCC) separated itself from the Southeastern Electric Reliability Council (SERC) in the mid-1990s and all time series data have been adjusted. In 1998, several utilities realigned from Southwest Power Pool (SPP) to SERC. Adjustments were made to the information to account for the separation and to address the tracking of shared reserve capacity that was under long-term contracts with multiple members. Name changes altered both the Mid-Continent Area Power Pool (MAPP) to the Midwest Reliability Organization (MRO) and the Western Systems Coordinating Council (WSCC) to the Western Electricity Coordinating Council (WECC). The MRO membership boundaries havealtered over time, but WECC membership boundaries have not. The utilities in the associated regional entity identified as the Alaska System Coordination Council (ASCC) dropped their formal particip ation in NERC. Both the States of Alaska and Hawaii are not contiguous with the other continental States and have no electrical interconnections. At the close of calendar year 2005, the following reliability regional councils were dissolved: East Central Area Reliability Coordination Agreement (ECAR), Mid-Atlantic Area Council (MAAC), and Mid-America Interconnected Network (MAIN). On January 1, 2006, the Reliability First Corporation (RFC) came into existence as a new regional reliability council. Individual utility membership in the former ECAR, MAAC, and MAIN councils mostly shifted to RFC. However, adjustments in membership as utilities joined or left various reliability councils impacted MRO, SERC, and SPP. The Texas Regional Entity (TRE) was formed from a delegation of authority from NERC to handle the regional responsibilities of the Electric Reliability

## U.S. Energy Information Administration/Electric Power Annual 2009 80 

## Council of Texas (ERCOT). The revised delegation agreements covering all the regions were approved by the Federal Energy Regulatory Commission on March 21, 2008. Reliability Councils that are unchanged include: Florida Reliability Coordinating Council (FRCC), Northeast Power Coordinating Council (NPCC), and the Western Electricity Coordinating Council (WECC). The historical time series have not been adjusted to account for individual membership shifts. The new NERC Regional Entity names are as follows:

Florida Reliability Coordinating Council (FRCC),

Midwest Reliability Organization (MRO),

Northeast Power Coordinating Council (NPCC),

Reliability First Corporation (RFC),

Southeastern Electric Reliability Council (SERC),

Southwest Power Pool (SPP),

Texas Regional Entity (TRE), and

Western Electricity Coordinating Council (WECC). Concept of Demand within the EIA-411 : Historically, the Form EIA-411 has used the electric power industry's methodology for examining aggregated supply and demand. To get to the megawatts of power that are determined to be available for planning purposes each year, different categories are subtracted from the theoretical true totals. The definitions for demand are as follows:

Net Internal Demand : Internal Demand less Direct Control Load Management and Interruptible Demand.

Internal Demand : To collect these data, NERC develops a Total Internal Demand that is the sum of the metered (net) outputs of all generators within the system and the metered line flows into the system, less the metered line flows out of the system. The demand of station service or auxiliary needs (such as fan motors, pump motors, and other equipment essential to the operation of the generating units ) is not included nor are any requirement customer (utility) load or capacity found behind the line meters on the system.

Direct Control Load Management : Demand-Side Management that is under the direct control of the system operator. DCLM may control the electric supply to individual appliances or equipment on customer premises; it does not included Interruptible Demand.

Interruptible Demand : The magnitude of customer demand that, in accordance with contractual arrangements, can be interrupted at the time of the Regional Council’s seasonal peak by direct control of the System Operator or by action of the customer at the direct request of the System Operator.
Sensitive Data (Formerly Identified as Data Confidentiality). Power flow cases and maps are considered business sensitive.



# Form EIA-412 [Terminated] The Form EIA-412 was used annually to collect accounting, financial, and operating data from major publicly 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 megawatthours of sales for resale for the two previous years, as reported on the Form EIA-861, “Annual Electric Utility Report,” wererequired to submit the Form EIA-412. The Form EIA412 was made available in January to collect data as of the end of the preceding calendar year. The completed surveys were due to EIA on or before April 30. Instrument and Design History. The Federal Power Commission (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. Beginning in 1996 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 fit 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, Michigan); 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. The form was terminated after the 2003 data year.

Issues within Historical Data Series Beginning with the 2001 data collection, the plant statistics reported on Schedule 9 were also collected from unregulated entities that own plants with a nameplate capacity of 10 megawatts or greater. Also beginning with the 2003 collection, the transmission

## U.S. Energy Information Administration/Electric Power Annual 2009 81 

## data reported in Schedules 10 and 11 were collected from each generation and transmission cooperative owning transmission lines having a nominal voltage of 132 kilovolts or greater. For 2001 - 2003, California Department of Water Resources - Electric Energy Fund data were included in the EIA-412 data tables. In response to the energy shortfall in California, in 2001 the California 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 revenue collected was $5,501,000,000 with purchased power costs of $12,055,000,000. Their 2002 revenue collected was $4,210,000,000 with purchased power costs of $3,827,749,811. Their 2003 revenue collected was $4,627,000,000 with purchased power costs of $4,732,000,000. The California Public Utility Commission was required by statute to establish the procedures for retail revenue recovery mechanisms for their purchase power costs in the future. Sensitive Data (Formerly Identified as Data Confidentiality). The nonutility data collected on Schedule 9 “Electric Generating Plant Statistics” for “Cost of Plant” and “Production Expenses,” are considered business sensitive.


# Form EIA-423 [Replaced in 2008 by the Form EIA-923] The Form EIA-423, “Monthly Cost and Quality of Fuels for Electric Plants Report,” collected information from selected electric generating plants in the United States. The data collected on this survey included the cost and quality of fossil fuels delivered to nonutility plants to produce electricity. These plants included independent power producers (including those facilities that formerly reported on the FERC Form 423) and commercial and industrial combined heat and power producers whose total fossil-fueled nameplate generating capacity is 50 or more megawatts. Instrument and Design History. The Form EIA-423 8 

## was originally implemented in January 2002 to collect monthly cost and quality data for fossil fuel receipts from owners or operators of nonutility electricity generating plants. It was terminated on January 1, 2008, and replaced by the Form EIA-923, "Power Plant Operations Report."

8 Due to the restructuring of the electric power industry, many plants which had historically submitted this information for utility plants on the FERC Form 423 (see subsequent section) were being transferred to the nonutility sector. As a result, a large percentage of fossil fuel receipts were no longer being reported. The Form EIA-423 was implemented to fill this void and to capture the data associated with existing nonregulated power producers. Its design closely follows that of the FERC Form 423. 

## Issues within Historical Data Series Natural gas values for 2001 forward do not include blast furnace gas or other gas. Sensitive Data (Formerly Identified as Data Confidentiality). Plant fuel cost data collected on the survey are considered business sensitive. State and national level aggregations will be published in this report if sufficient data are available to avoid disclosure of individual company and plant level costs.



# FERC Form 423 [Replaced in 2008 by Form EIA-923] The Federal Energy Regulatory Commission (FERC) Form 423, “Monthly Report of Cost and Quality of Fuels for Electric Plants,” was administered by FERC. The data were downloaded from the Commission’s website into an EIA database. The Form was filed by approximately 600 regulated plants. To meet the old criteria for filing, a plant must have had a total steamturbine electric generating capacity and/or combinedcycle (gas turbine with associated steam turbine) generating capacity of 50 or more megawatts. Onlyfuel delivered for use in steam-turbine and combinedcycle units was reported. Fuel received for use in gasturbine or internal-combustion units that was not associated with a combined-cycle operation is not reported. The 2007 data collection represents the last year where the information came from the FERC Form 423. Instrument and Design History. On July 7, 1972, the Federal Power Commission (FPC) issued Order Number 453 enacting the New Code of Federal Regulations, Section 141.61, legally creating the FPC Form 423. Originally, the form was used to collect data only on fossil-steam plants, but wasamended in 1974 to include data on internalcombustion and combustion-turbine units. The FERC Form 423 replaced the FPC Form 423 in January 1983. The FERC Form 423 eliminated peaking units, for which data were previously collected on the FPC Form 423. In addition, the generator nameplate capacity threshold was changed from 25 megawatts to 50 megawatts. This reduction in coverage eliminated approximately 50 utilitie s and 250 plants. All historical FPC Form 423 data in this publication wererevised to reflect the new generator-nameplatecapacity threshold of 50 or more megawatts reported on the FERC Form 423. In January 1991, the collection of data on the FERC Form 423 was extended to include combined-cycle units. Historical data have not been revised to include these units. Starting with the January 1993 data, the FERC began to collect the data directly from the respondents. On January 1, 2008, EIA assumed responsibility for collection and the information is now under the Form EIA-923, "Power Plant Operations Report."

## U.S. Energy Information Administration/Electric Power Annual 2009 82 

## Formulas and Methodologies. Data for the FERC Form 423 were collected at the plant level. These data were then used in the same formulas used by the Form EIA-423 to produce aggregates and averages for each fuel type at the State, Census division, and U.S. levels. Issues within Historical Data Series. The FERC Form 423 data published by EIA have been reviewed for consistency between volumes and prices and for their consistency over time. Receipts data for regulated utilities were compiled by EIA from data collected by the Federal Energy Regulatory Commission (FERC) on the FERC Form 423. These data were collected by FERC for regulatory rather than statistical and publication purposes. EIA did not attempt to resolve any late filing issues in the FERC Form 423 data. Due to the estimation procedure discussed previously, 2003 and later data cannot be directly compared to previous years’ data. Sensitive Data (Formerly Identified as Data Confidentiality). Data collected on FERC Form 423 are not considered to be business sensitive.


# Form EIA-767 [Replaced by Forms EIA-860 and EIA-923] The Form EIA-767 was used to collect data annually on plant operations and equipment design, including boiler, generator, cooling system, air pollution control equipment, and stack characteristics. Data were collected from 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 more megawatts. The entire form was filed by approximately 800 power plants with a nameplate capacity of 100 or more megawatts. An additional 600 power plants with a nameplate capacity under 100 megawatts submitted information only on fuel consumption and quality, boiler and generator configuration, and nitrogen oxides, mercury, particulate matter, and sulfur dioxide controls. Instrument and Design History. The Federal Energy Administration Act of 1974 (Public Law 93-275) defines the legislative authority to collect these data. The predecessor form, FPC-67, “Steam-Electric Plant Air and Water Quality Control Data,” was used to collect data from 1969 to 1980, when the form number was changed to Form EIA-767. In 1982, the form was completely redesigned and retitled Form EIA-767, “Steam-Electric Plant Operation and Design Report.” In 1986, the respondent universe of 700 was increased to 900 to include plants with nameplate capacity from 10 megawatts to 100 megawatts. In 2002, the respondent universe was increased by almost 1,370 plants with the addition of non-utility plants. Collection of data via the form was suspended for the 2006 data year

Estimation of EIA-767 Data . No estimation of Form EIA-767 data was performed, as 100 percent of the forms were collected. . Starting for the collection of 2007 calendar year data, most of the Form EIA-767 information is now collected on either the revised Form EIA-860, "Annual Electric Generator Report" or the new Form EIA-923, "Power Plant Operations Report."

Issues within Historical Data Series None. Sensitive Data (Formerly Identified as Data Confidentiality).Historical latitude and longitude data collected on the Form EIA-767 are considered business sensitive. 

# Form EIA-860 The Form EIA-860 is a mandatory census of all existing and planned 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 individual generator level. Certain power plant environmental related data are now collected at the boiler level. These data include environmental equipment design parameters and boiler air emission standards and boiler emission controls. The Form EIA-860 is made available in January to collect data for the previous year and is due to EIA by February 15 of each year. 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 January 1, 1999. In 1989, the Form EIA-867, "Annual Nonutility Power Producer Report," was initiated to collect plant data on unregulated 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-860B, "Annual Electric Generator Report – Nonutility." The Form EIA-860B was a mandatory survey of all existing and planned nonutility electric generating facilities in the United States with a total generator nameplate capacity of 1 or more megawatts. Beginning with data collected for the year 2001, the infrastructure data collected on the Form EIA-860A

## U.S. Energy Information Administration/Electric Power Annual 2009 83 

## and the Form EIA-860B were combined into the new Form EIA-860 and the monthly and annual versions of the Form EIA-906. The Federal Energy Administration Act of 1974 (Public Law 93-275) defines the legislative authority to collect these data. Starting with the 2007 data,, design parameters data formerly collected on Form EIA-767 are collected on Form EIA-860. These include design parameters associated with certain steam-electric plants’ boilers, cooling systems, flue gas particulate collectors, flue gas desulfurization units and stacks and flues. Estimation of EIA-860 Data.Of the 17,879 existing generators in the 2009 For EIA-860 frame, imputation was performed on 5 generators. These 5 generators account for less than 0.0006% of the existing capacity. Imputation was performed at the generators levels using the respondents’ 2008 data.

Issues within Historical Data Series Categorization of Capacity by Business Sector

Some capacity in 2001 through 2004 is classified based on the operating company's classification as an electric utility or an independent power producer. Starting in the Electric Power Annual 2006, capacity by producer type was determined at the generating plant level for 2005 and 2006, based on whether the plant is an electric utility plant or an electric nonutility plant. Therefore, the revised capacity by producer type for 2005 is comparable to the capacity for 2006 and later years, by producer type. The previously published 2005 capacity by producer type was determined based on the operating company’s classification of electric utility or electric nonutility. : There are a small number of electric utility combined heat and power plants, as well as a small number of industrial and commercial generating facilities that are not combined heat and power. For the purposes of this report the data for these plants are included, respectively, in the following categories: “Electricity Generators, Electric Utilities,” “Combined Heat and Power, Industrial,” and “Combined Heat and Power, Commercial.”

Planned Capacity : Delays and cancellations may have occurred subsequent to respondent data reporting as of December 31 of the data year. Capacity by Energy Source: In the Electric Power Annual 2005 , certain petroleumfired capacity was misclassified as natural gas-fired capacity for 1995 – 2003. This has been corrected in the Electric Power Annual 2006. Corrections were noted as revised data.

Prior to the Electric Power Annual 2005, the capacity for generators for which natural gas or petroleum was the most predominant energy source was presented in the categories “petroleum only,” “natural gas only” and “dual-fired.” The “dual-fired” category, which wasEIA’s effort to infer which generators could fuelswitch between natural gas and fuel oil, included only the capacity of generators for which the most predominant energy source and second most predominant energy source were reported as natural gas or petroleum. Beginning in 2005 capacity is assigned to energy source based solely on the most predominant (primary) energy source reported for a generator. The “dual-fired” category was eliminated. Separately, summaries of capacity associated with generators with fuel-switching capability are presented for 2005 and later years.. These summaries are based on data collected from new questions added to the Form EIA-860 survey that directly address the ability of generators to switch fuels and co-fire fuels.

Sensitive Data (Formerly Identified as Data Confidentiality). The tested heat rate data collected on the Form EIA-860 are considered business sensitive.



# 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 3,300 respondents. About 3,200 are electric utilities, and the remainder is nontraditional entities such as energy service providers, or the unregulated subsidiaries of electric utilities and power marketers. The data collected are used to maintain and update the ERUS electric power industry participant frame database. The Form EIA-861 is made available in January of each year to collect data as of the end of the preceding calendar year and is due by April 30. Transportation Sector. Prior to 2003, sales of electric power to the Transportation sector of the U. S. economy were included in the Other sector, along with sales to customers for public buildings, traffic signals, public street lighting, and sales to irrigation consumers. Beginning with the 2003 collection cycle, sales to the Transportation sector are collected separately. Sales to public-sector customers for public buildings, traffic signals and street lighting, previously reported in the Other sector, were reclassified as Commercial sector sales. Sale s to irrigation customers, where separately identified, were reclassified to the Industrial sector. On the Form EIA-861, the Transportation sector is defined as electrified rail, primarily urban transit, light rail, automated guideway, and other rail systems whose primary propulsive energy source is electricity. Electricity sales to transportation sector consumers whose primary propulsive energy source is not

## U.S. Energy Information Administration/Electric Power Annual 2009 84 

## electricity (i.e., gasoline, diesel fuel, etc.) are not included.
Benchmark statistics were reviewed from outside surveys, most notably the U.S. Department of Transportation, Federal Transit Administration’s National Transportation Database, a source previously used by EIA to estimate electricity transportation consumption. The U.S. Department of Transportation (DOT) survey indicated the State and city locations of expected respondents. The EIA-861 survey methodology assumed that sales, revenue, and customer counts associated with these mass transit systems would be provided by the incumbent utilities in these areas, relying on information drawn routinely from rate schedules and classifications designed to serve the sector separately and distinctly. In 2007, 72 respondents reported transportation data in 28 States.
Imputation. The Electric Power Annual (EPA) reports total retail sales volumes (megawatthours) and customer counts in States with deregulated markets as the sum of bundled sales reported by full-service providers and delivery reported by transmission and distribution utilities. ERUS has concluded that the retail sales data reported by delivery utilities are more reliable than data reported by power marketers and Energy Service Providers (ESPs). The reporting methodology change uses sales volumes and customer counts reported by distribution utilities, and add only an incremental revenue value, representing revenue associated with missing sales assumed to be attributable to the ESPs that were under-represented in the survey frame. In some cases, adjustments are also made to retail sales, revenue, and customer counts associated with underreporting of delivery volumes by one or more of the distribution utilities. In thos e cases, EIA assumes that total load served by those utilities is accurate, and that any underreporting of delivery volumes resulted from misclassifying actual delivery volumes as bundled sales. Therefore, in those instances EIA adjusted upwards the delivery volumes, revenues, and customer counts and made a corresponding equivalent offset (reduction) to the bundled sales by State and end-use sector. Data for 2009 reflect imputed retail sales data to account for non-respondents on Form EIA-861. The imputation methodology used is the same as that used in preparing the Electric Power Monthly (whose retailsales data are drawn from Form EIA-826). Form EIA826 is a monthly stratified sample of approximately 475 investor-owned and public utilities, as well as a census of energy service providers and power marketers. If an EIA-861 respondent did not file an annual form for 2009, their data were assumed to be the amount imputed during the year using the EIA-826 sample form collection and imputation process. Instrument and Design History . The Form EIA-861 was implemented in January 1985 for collection of data as of year-end 1984. The Federal Energy Administration Act of 1974 (Public Law 93-275) defines the legislative authority to collect these data.
Data Reconciliation. The EPA reports total retail sales volumes (megawatthours) and customer counts in States with deregulated markets as the sum of bundled sales reported by full-service providers and delivery reported by transmission and distribution utilities. ERUS has conclude d that the retail sales data reported by delivery utilities are more reliable than data reported by power marketers and ESPs.
Average Retail Price of Electricity. This represents the cost per unit of electricity sold and is calculated by dividing retail electric revenue by the corresponding sales of electricity. The average retail price of electricity is calculated for all consumers and for each end-use sector. State-level weighted average prices per unit of sales are calculate d as the ratio of revenue to sales. The electric revenue used to calculate the average retail price of electricity is the operating revenue reported by the electric 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 also include ratepayer reimbursements for State and Federal income taxes and taxes other than income taxes paid by the utility. The average retail price of electricity reported in this publication by sector repres ents a weighted average of consumer revenue and sales within sectors and across 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.

Issues within Historical Data Series Beginning in 2003 the Other sector has been eliminated. Data previously assigned to the Other sector have been reclassified as follows: lighting for public buildings, streets, and highways, interdepartmental sales, and other sales to public authorities are now included in the Commercial sector; agricultural and irrigation sales where separately identified are now included in the Industrial

## U.S. Energy Information Administration/Electric Power Annual 2009 85 

## sector; and a new sector, Transportation, includes electrified rail and various urban transit systems (such as automated guideway, trolley, and cable) where the principal propulsive energy source is electricity. Comparisons of data across years should include consideration of these reclassification changes. Changes from year to year in consumer counts, sales and revenues, particularly involving the commercial and industrial consumer sectors, may result from respondent implementation of changes in the definitions of consumers, and reclassifications. Utilities and energy service providers may classify commercial and industrial customers based on either NAICS codes or demands or usage falling within specified limits by rate schedule. Also, the number of ultimate customers is an average of the number of customers at the close of each month. Demand-Side Management: The following definitions are supplied to assist in interpreting Tables 9.1 through 9.5. Utility costs reflect the total cash expenditures for the year, in nominal dollars, that flow out to support demand-side management (DSM) programs.

Actual Peak Load Reduction.The actual reduction in annual peak load achieved by all program participants during the reporting year, at the time of annual peak load, as opposed to the installed peak load reduction capability (Potential Peak Load Reduction). Actual peak load reduction is reported by large utilities only.

Energy Savings.The change in aggregate electricity use (measured in megawatthours) for consumers that participate in a utility DSM program. These savings represent changes at the consumer's meter (i.e., exclude transmission and distribution effects) and reflect only activities thatare undertaken specifically in response to utilityadministered programs, including those activities implemented by third partie s under contract to the utility.

Large Utilities.Those electric utilities with annual sales to ultimate customers or sales for resale greater than or equal to 150 million kilowatthours in 1998-2009 and, for years prior, the threshold was set at 120 million kilowatthours.

Potential Peak Load Reductions. The potential peak load reduction as a result of load management, and also the actual peak load reduction achieved by energy efficiency programs. Wholesale Trade Sensitive Data (Formerly Identified as Data Confidentiality).Data collected on the Form EIA861 are not considered to be business sensitive.

# . Form EIA-906 [Replaced in 2007 by Form EIA-923] The Form EIA-906 was used to collect plant-level data on generation, fuel consumption, stocks, and fuel heat content, from electric utilities and nonutilities. Data were collected monthly from a model-based sample of approximately 1,700 utility and nonutility electric power plants. The form was also used to collect these statistics from another 2,667 plants (i.e., all other generators 1 MW or greater) on an annual basis. The 2007 data collection represents the last year where the information came from the Form EIA-906. Starting with the collection of 2008 calendar year data, the Form EIA-906 information is now collected on a replacement form (the Form EIA-923). The monthly data for Form EIA-906 is now being collected on the replacement form starting in January of 2008. Instrument and Design History. The Bureau of Census and the U.S. Geological 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 implemented the Form FPC-4. The Federal Power Act, Section 311 and 312, and FPC Order 141 defined the legislative authority to collect power production data. The Form EIA-759 replaced the Form FPC-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 2000, the form was modified to include useful thermal output data. In January 2001, Form EIA-906 superseded FormsEIA-759 and EIA-900. In January 2004, Form EIA920 superseded Form EIA-906 for those plants defined as combined heat and power plants; all other plants that generate electricity continue to report on Form EIA-906. The Federal Energy Administration Act of 1974 (Public Law 93-275) defines the legislative authority to collect these data. In January 2008, the Form EIA-923 superseded this form. Issues within Historical Data Series There were a small number of electric commercial and industrial- only plants that are included in the combined heat and power category. For the purposes of this report the data for these plants were included, respectively, in the following categories: “Electricity Generators, Electric Utilities,” “Combined Heat and

## U.S. Energy Information Administration/Electric Power Annual 2009 86

= The Form EIA-920, “Combined Heat and Power Plant Report” was used to collect plant-level data on generation, fuel consumption, stocks, and fuel heat content of combined heat and power (CHP) plants. Data were collected monthly from a sample of plants. The form was also used to collect the statistics from combined heat and power plants on an annual basis

. Instrument and Design History. In January 2004, Form EIA-920 superseded Form EIA-906 for those plants defined as combined heat and power plants; all other plants that generate electricity continue to report on Form EIA-906. Starting with the collection of 2007 calendar year data, the Form EIA-920 information isnow collected on a replacement form (the Form EIA923). The monthly data for Form EIA-920 began collection on the replacement form in January of 2008. (For further information on predecessor forms, see the discussion of the EIA-906 survey, above.) The Federal Energy Administration Act of 1974 (Public Law 93-275) defines the legislative authority to collect these data. Issues within Historical Data Series There are a small number of electric commercial and industrial only plants that are included in the combined heat and power category. For the purposes of this report the data for these plants are included, respectively, in the following categories: “Electricity Generators, Electric Utilities,” “Combined Heat and Power, Industrial,” and “Combined Heat and Power, Commercial.” No information on the production of UTO or fuel consumption for UTO was collected or estimated for the electric utility combined heat and power plants

 Form EIA-923, “Power Plant Operations Report,” is used to collect information on receipts and cost of fossil fuels, fuel stocks, generation, consumption of fuel for generation, and environmental data (e.g., emission controls and cooling systems). Data are collected from a monthly sample of approximately 1,600 plants, which includes a census of nuclear and pumped storage hydroelectric plants. The plants in the monthly sample report their receipts, cost and stocks of fossil fuels, electric power generation, and the total consumption of fuels for both electric power generation and, if a combined heat and power plant, useful thermal output. At the end of the year, the monthly respondents report their annual source and disposition of electric power (nonutilities only), and ifapplicable, the environmental data on the Form EIA923 Supplemental Form (Schedules 6, 7, and 8A to 8F). Approximately 3,300 plants, representing all generators not included in the monthly sample and with a nameplate capacity of 1 MW or more, report data on the entire form (Schedules 1 to 8F, as applicable) annually

. In addition to electric power generating plants, respondents include fuel storage terminals without generating capacity that receives shipments of fossil fuels for eventual use in electric power generation. The monthly data are due by the last day of the month following the reporting period. Receipts of fossil fuels, fuel cost and quality information, and fuel stocks at the end of the reporting period are all reported at the plant level. Fuel receipts and costs are collected from plants with a nameplate capacity of 50 MW or more and burn fossil fuels. Plants that burn organic fuels and have a steam turbine capacity of at least 10 megawatts report consumption at the boiler level and generation at the generator level for each month, regardless of whether the plant reports in the monthly sample or reports once a year (annually). For all other plants, consumption is reported at the prime-mover level. For these plants, generation is reported eitherat the prime-mover level or, for noncombustible sources (e.g., wind, nuclear), at the prime-move and energy source level (including generating unit for nuclear only). The source and disposition of electricity is reported annually for nonutilities at the plant level,as is revenue from sales for resale. Additional operational data, including environmental data, are collected annually from facilities that have a steam turbine capacity of at least 10 megawatts. Instrument and Design History : Receipts and Cost and Quality of Fossil Fuels On July 7, 1972, the Federal Power Commission (FPC) issued Order Number 453 enacting the New Code of Federal Regulations, Section 141.61, legally creating the FPC Form 423. Originally, the form was used to collect data only on fossil-steam plants, butwas amended in 1974 to include data on internalcombustion and combustion-turbine units. The FERC Form 423 replaced the FPC Form 423 in January 1983. The FERC Form 423 eliminated peaking units, for which data were previously collected on the FPC

## U.S. Energy Information Administration/Electric Power Annual 2009 87 

## Form 423. In addition, the generator nameplate capacity threshold was changed from 25 megawatts to 50 megawatts. This reduction in coverage eliminated approximately 50 utilitie s and 250 plants. All historical FPC Form 423 data in this publication wererevised to reflect the new generator-nameplatecapacity threshold of 50 or more megawatts reported on the FERC Form 423. In January 1991, the collection of data on the FERC Form 423 was extended to include combined-cycle units. Historical data have not been revised to include these units. Starting with the January 1993 data, the FERC began to collect the data directly from the respondents. The Form EIA-423 was originally implemented in January 2002 to collect monthly cost and quality data for fossil fuel receipts from owners or operators of nonutility electricity generating plants. Due to the restructuring of the electric power industry, many plants which had historically submitted this information for utility plants on the FERC Form 423 (see above) were being transferred to the nonutility sector. As a result, a large percentage of fossil fuel receipts were no longer being reported. The Form EIA-423 was implemented to fill this void and to capture the data associated with existing non-regulated power producers. Its design closely followed that of the FERC Form 423.
Both the Form EIA-423 and FERC-423 were superseded by Form EIA-923 (Schedule 2) in January of 2008. The EIA-923 maintains the same 50 megawatt threshold for these data. However, not all data are collected monthly on the new form. Beginning with 2008 data, a sample of the respondents will report monthly, with the remainder reporting annually (monthly values will be imputed via regression). For 2007, Schedule 2 annual data will not be collected or imputed. Most of the plants required to report on Schedule 2 already submitted their 2007 receipts data on a monthly basis. Generation and Consumption The Bureau of Census and the U.S. Geological 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 implemented the Form FPC-4. The Federal Power Act, Section 311 and 312, and FPC Order 141 defined the legislative authority to collect power production data. The Form EIA-759 replaced the Form FPC-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 2000, the form was modified to include useful thermal output data. In January 2001, Form EIA-906 superseded FormsEIA-759 and EIA-900. In January 2004, Form EIA920 superseded Form EIA-906 for those plants defined as combined heat and power plants; all other plants that generate electricity continue to report on Form EIA-906. The Federal Energy Administration Act of 1974 (Public Law 93-275) defines the legislative authority to collect these data. Forms EIA-906 and EIA-920 were superseded by survey form EIA-923 beginning in January 2008 with the collection of annual 2007 data and monthly 2008 data.

Steam Electric Plant Operational Data The Federal Energy Administration Act of 1974 (Public Law 93-275) defines the legislative authority to collect these data. The predecessor form, FPC-67, “Steam-Electric Plant Air and Water Quality Control Data,” was used to collect data from 1969 to 1980,when the form number was changed to Form EIA767. In 1982, the form was completely redesigned and retitled Form EIA-767, “Steam-Electric Plant Operation and Design Report.” In 1986, the respondent universe of 700 was increased to 900 to include plants with nameplate capacity from 10 megawatts to 100 megawatts. In 2002, the respondent universe increased to above 1,370 plants plus the addition of non-utility plants. Collection of data via the Form EIA-767 was suspended for the2006 data year, but was resumed on the Form EIA923 for data year 2007. For respondents selected tobe in the monthly sample for Form EIA-906 or EIA920 in 2007, and were thus were not annual filers for Form EIA-923, this data was collected for 2007 via a one-time supplemental filing in 2008. Data Processing and Data System Editing. Respondents are encouraged to enter data directly into a computerized database via the e-filing system. A variety of automated quality control mechanisms are run during this process, such as range checks and comparisons with historicaldata. These edit checks were performed as the data were provided, and many problems that are encountered are resolved during the reporting process. Those plants that are unable to use the electronic reporting medium provide the data in hard copy, typically via fax. These data were manually entered into the computerized database. The data were subjected to the same edits as those that were electronically submitted. If the reported data appeared to be in error and the data issue could not be resolved by follow up contact with the respondent, or if a facility was a nonrespondent, a regression methodology was used to impute for the facility.

## U.S. Energy Information Administration/Electric Power Annual 2009 88 

## Imputation. For data collected monthly, regression prediction, or imputation, is done for all missing data including non-sampled units and any nonrespondents. For data collected annually, imputation is done for nonrespondents. For gross generation and total fuel consumption, multiple regression is used for imputation. For gross generation, the regressors are prior year average generation for the same fuel, prior year average generation from other fuels, and nameplate capacity. Regressors for total fuel consumption are prior year average fuel consumption from the same fuel, prior year average consumption from other fuels, and nameplate capacity. For stocks, a linear combination of the prior month’s ending stocks value and the current month’s consumption and receipts values is used. Only approximately 0.01% of the national total gross generation for 2009 reported here is imputed, although this will vary by State and energy source.
Net generation, where not reported, is estimated by using a fixed ratio to gross generation by prime-mover type. Receipts of Fossil Fuels. Receipts data, including cost and quality of fuels, are collected at the plant level from selected electric generating plants and fossil-fuel storage terminals in the United States. These plants include independent power producers, electric utilities, and commercial and industrial combined heat and power producers whose total fossil-fueled nameplate capacity is 50 megawatts or more (excluding storage terminals, which do not produce electricity). The data on cost and quality of fuel shipments are then used in the following formulas to produce aggregates and averages for each fuel type at the State, Census division, and U.S. levels. For these formulas, receipts and average heat content are at the plant level. For each geographic region, the summation sign,  represents the sum of all facilities in that geographic region. For coal, units for receipts are in tons and units for average heat contents (A) are in million Btu per ton. For petroleum, units for receipts are in barrels and units for average heat contents (A) are in million Btu per barrel. For gas, units for receipts are in thousand cubic feet (Mcf) and units for average heat contents (A) are in million Btu per thousand cubic foot.
For each of the above fossil fuels:

Total Btu = where i denotes a facility; R i 

## = receipts for facility i ; A i 

## = average heat content for receipts at facility i ;

Weighted Average Btu =

where i denotes a facility; R i 

## = receipts for facility i; and, A i 

## = average heat content for receipts at facility i. The weighted average cost in cents per million Btu is calculated using the following formula:

Weighted Average Cost =

where i denotes a facility; R i 

## = receipts for facility i ; A i 

## average heat content for receipts at facility i ; and C i 

## = cost in cents per million Btu for facility i

. The weighted average cost in dollars per unit (i.e., tons, barrels, or Mcf) is calculated using the following formula:

Weighted Average Cost =

where i denotes a facility; R i 

## = receipts for facility i ; A i 

## = average heat content for receipts at facility i ; and, C i 

## = cost in cents per million Btu for facility i

. Power Production, Fuel Stocks, and Fuel Consumption Data. The Bureau of Census and the U.S. Geological 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 implemented the Form FPC-4. The Federal Power Act, Section 311 and 312, and FPC Order 141 defined the legislative authority to collect power production data. The Form EIA-759 replaced the Form FPC-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 2000, the form was modified to include useful thermal output data.

In January 2004, Form EIA920 superseded Form EIA-906 for those plants defined as combined heat and power plants; all other plants that generate electricity continue to report on Form EIA-906. The Federal Energy Administration Act of 1974 (Public Law 93-275) defines the legislative authority to collect these data. In January 2004, Form EIA-920 superseded Form EIA-906 for those plants defined as combined heat and power plants; all other plants that generate electricity continue to report on Form EIA-906.

## . Municipal Solid Waste (MSW) consumption for generation of electric power is split into its biogenic and non-biogenic components beginning with 2001 data by the following methodology: The reported tonnage of MSW is reported on the Form EIA-923. The composition of MSW and categorization of the components were obtained from the Environmental Protection Agency publication, Municipal Solid Waste in the United States: 2005 Facts and Figures. The Btu contents of the components of MSW were obtained from various sources. The potential quantities of combustible MSW discards (which include all MSW material available for combustion with energy recovery, discards to landfill, and other disposal) were multiplied by their respective Btu contents. The EPA-based categories of MSW were then classified into renewable and non-renewable groupings. From this, EIA calculated how much of the energy potentially consumed from MSW was attributed to biogenic components and how much to non-biogenic components (see Table 1 and 2, below). 10

10 Biogenic components include newsprint, paper, containers and packaging, leather, textiles, yard trimmings, food wastes, and wood. Non-biogenic components include plastics, rubber and other miscellaneous non-biogenic waste. 

## These values are used to allocate the net and gross generation published in the Electric Power Monthly and Electric Power Annual generation tables. The tons of biogenic and non-biogenic components were estimated with the assumption that glass and metals were removed prior to combustion. The average Btu/ton for the biogenic and non-biogenic components is estimated by dividing the total Btu consumption by the total tons. Published net generation attributed to biogenic MSW and non-biog enic MSW is classified under Other Renewables and Other, respectively.Table 1.

Useful Thermal Output. With the implementation of the Form EIA-923, “Power Plant Operations Report,” in 2008, combined heat and power (CHP) plants are required to report total fuel consumed and electric power generation4. Beginning with preliminary January 2008 data, EIA estimated the allocation of the total fuel consumed at CHP plants between electric power generation and useful thermal output. The estimated allocation methodology is summarized in the following paragraphs. The methodology was retroactively applied to 2004-2007 data. Prior to 2004, useful thermal output was collect on the Form EIA-906 and an estimated allocation of fuel for electricity was not necessary. First, an efficiency factor is determined for each plant and prime mover type. Based on data for electric power generation and useful thermal output (UTO) collected in 2003 (on Form EIA-906, “Power Plant Report”) efficiency was calculated for each prime mover type at a plant. The efficiency factor is the total output in Btu, including electric power and useful thermal output (UTO), divided by the total input in Btu. Electric power is converted to Btu at 3,412 Btu per kilowatthour. Second, to calculate the amount of fuel for electric power, the gross generation in Btu is divided by the efficiency factor. The fuel for UTO is the difference between the total fuel reported and the fuel for electric power generation. UTO is calculated by multiplying the fuel for UTO by the efficiency factor.

## U.S. Energy Information Administration/Electric Power Annual 2009 90 

## In addition, if the total fuel reported is less than the estimated fuel for electric power generation, then the fuel for electric power generation is equal to the total fuel consumed, and the UTO will be zero.


# Issues within Historical Data Series Receipts and Cost and Quality of Fossil Fuels Values for receipts of natural gas for 2001 forward do not include blast furnace gas or other gas.
Historical data collected on FERC Form 423 and published by EIA have been reviewed for consistency between volumes and prices and for their consistency over time. However, these data were collected by FERC for regulatory rather than statistical and publication purposes. EIA did not attempt to resolve any late filing issues in the FERC Form 423 data. In 2003, EIA introduced a procedure to estimate for late or non-responding entities who were required to report on the FERC Form 423. Due to the introduction of this procedure, 2003 and later data cannot be directly compared to previous years’ data. Prior to 2008, regulated plants reported receipts data on the FERC Form 423. These plants, along with unregulated plants, now report receipts data on Schedule 2 of Form EIA-923. Because FERC issued waivers to Form 423 filing requirements to some plants who met certain criteria, and because not all types of generators were required to report (only steam turbines and combined cycle units reported), a significant number of plants either did not submit fossil fuel receipts data or submitted only a portion of their fossil fuel receipts. Since Form EIA-923 does not have exemptions based on generator type, or reporting waivers, receipts data from 2008 and later cannot be directly compared to previous years’ data for the regulated sector. Furthermore, there may be a notable increase in fuel receipts beginning with January 2008 data. Also beginning with January 2008 data, tables for total receipts will include imputed quantities for plants with capacity one megawatt or more, to be consistent with other electric power data. Previous published receipts data were from plants over a 50 megawatt threshold, which was a legacy of their original collection as information for a regulatory agency, not as a survey to provide more meaningful estimates of totals for statistical purpos es. Totals appeared to become smaller as more electric production came from unregulated plants, until the EIA-423 was created to help fill that gap. As a further improvement, estimation of all receipts for the universe normally depicted in the EPA ( i.e., one megawatt and above), with associated relative standard errors, provides a more complete assessment of the market.

Generation and Consumption Beginning in 2008, a new method of allocating fuel consumption between electric power generation and useful thermal output (UTO) was implemented (see above). This new methodology evenly distributes a combined heat and power (CHP) plant’s losses between the two output products (electric power and UTO). In the historical data, UTO was consistently assumed to be 80 percent efficient and all other losses at the plant were allocated to electric power. This change causes the fuel for electric power to be lower while the fuel for UTO is higher as both are given the same efficiency. This results in the appearance of an increase in efficiency of production of electric power between periods.
Steam Electric Plant Operational Data Due to suspension of Form EIA-767 in 2007, there is a one year break in this data series as data year 2006 could not be collected. Sensitive Data (Formerly identified as Data Confidentiality). Most of the data collected on the Form EIA-923 are not considered business sensitive. However, the total delivered cost of fuel delivered to nonutilities, commodity cost of fossil fuels, and reported fuel stocks at the end of the reporting period are considered business sensitive. The release of these data must adhere to EIA's “Policy on the Disclosure of Individually Identifiable Energy Information in the Possession of the EIA” (45Federal Register 59812 (1980)).

This section describes the methodology for calculating estimated emissions of carbon dioxide (CO 2

## ) from electric generating plants for 1989 through 2009, as well as the estimated emissions of sulfur dioxide (SO 2

## ) and nitrogen oxides (NO x

## ) from electric generating plants for 2001 through 2009. For a description of the methodology used for other years, see the technical notes to the Electric Power Annual 2003

. Methodology Overview Initial estimates of uncontrolled SO 2 

## and NO x 

## emissions for all plants are made by applying an emissions factor to fuel consumption data collected by EIA on the Form EIA-923. An emission factor is the average quantity of a pollutant released from a power plant when a unit of fuel is burned, assuming no use of pollution control equipment. The basic relationship is:

## U.S. Energy Information Administration/Electric Power Annual 2009 91 

## Emissions = Quantity of Fuel Consumed x Emission Factor Quantity is defined in physical units (e.g., tons of solid fuels, million cubic feet of gaseous fuels, and thousands of barrels of liquid fuels) for determining NO x 

## and SO 2 

## emissions. As discussed below, physical quantities are converted to millions of Btus for calculating CO 2 

## emissions. For some fuels, the calculation of SO 2 

## emissions requires including in the formula the sulfur content of the fuel measured in percentage of weight. Examples include coal and fuel oil. In these cases the formula is: Emissions = Quantity of Fuel Consumed x Emission Factor x Sulfur Content The fuels that require the percent sulfur as part of the emissions calculation are indicated in Table A1, which lists the SO 2 

## emission factors used for this report. In the case of SO 2 

## and NO x 

## emissions, the factor applied to a fuel can also vary with the combustion system: either a steam-producing boiler, a combustion turbine, or an internal combustion engine. In the case of boilers, NO x 

## emissions can also vary with the firing configuration of a boiler and whether or not the boiler is a wet-bottom or dry-bottom design. 11



## For SO 2 

## and NO x 

## , the initial estimate of uncontrolled emissions is reduced to account for the plant’s operational pollution control equipment, when data on control equipment are available from the historical Form EIA-767 survey (i.e., data for the years 2005 and earlier) and the EIA-860 survey for the years 2007 and 2008. A special case for removal of SO 2

## is the fluidized bed boiler, in which the sulfur removal process is integral with the operation of the boiler. The SO 2 

## emission factors shown in Table A1 for fluidized bed boilers already account for 90 percent removal of SO 2 

## since, in effect, the plant has no uncontrolled emissions of this pollutant. These distinctions are shown in Tables A1 and A2.

Although SO 2 

## and NO x 

## emission estimates are made for all plants, in many cases the estimated emissions can be replaced with actual emissions data collected by the U.S. Environmental Protection Agency’s Continuous Emissions Monitoring System (CEMS) program. (CEMS data for CO 2 

## are incomplete and are not used in this report.) The CEMS data account for the bulk of SO 2 

## and NO x 

## emissions from the electric power industry. For those plants for which CEMS data are available, the EIA estimates of SO 2 

## and NO x

11 A boiler’s firing configuration relates to the arrangement of the fuel burners in the boiler, and whether the boiler is of conventional or cyclone design. Wet and dry-bottom boilers use different methods to collect a portion of the ash that results from burning coal. For information on wet and dry bottom boilers, see the EIA Glossary at http://www.eia.gov/glossary/index.html . Additional information on wet and dry-bottom-boilers and on other asp ects of boiler design and operation, including the differences between conventional and cyclone designs, can be found in Babcock and Wilcox, Steam: Its Generation and Use , 41 st Edition, 2005. 

## emissions are employed for the limited purpose of allocating emissions by fuel, since the CEMS data itself do not provide a detailed breakdown of plant emissions by fuel. For plants for which CEMS data are unavailable, the EIA-computed values are used as the final emissions estimates. There are a number of reasons why the historical data are periodically revised. These include data revisions, revisions in emission and technology factors, and changes in methodology. For instance, the 2008 EPA report features a revision in historic CO2 values. This revision occurred due to a change in the accepted methodology regarding adjustments made for the percentage combustion of fuels. The emissions estimation methodologies are described in more detail below. CO 2 

## Emissions. CO 2 

## emissions are estimated using the information on fuel consumption in physical units and the heat content of fuel collected on the Forms EIA-923 (data for combined heat and power plants) and EIA-906 (all other power plants) for the years 1989 through 2006. In 2007, a new form was introduced, the Power Plant Operations Survey (Form EIA-923), which includes information on fuelconsumption previously part of the Form EIA906/EIA-920 Surveys. Fuel consumption data from the Form EIA-923 was used to estimate CO 2 

## . The heat content information is used to convert physical units to millions of Btu (MMBtu) consumed. To estimate CO 2 

## emissions, the fuel-specific emission factor from Table A3 is multiplied by the fuel consumption in MMBtu. The estimation procedure calculates uncontrolled CO 2 

## emissions. CO 2 

## control technologies are currently in the early stages of research and there are no operational systems installed. Therefore, no estimates of controlled CO 2 

## emissions are made. SO 2 

## and NO x 

## Emissions. To comply with environmental regulations controlling SO 2 

## emissions, many coal-fired generating plants have installed flue gas desulfurization (FGD) units. Similarly, NO x

## control regulations require many plants to install lowNO x 

## burners, selective catalytic reduction systems, or other technologies to reduce emissions. It is common for power plants to employ two or even three NO x 

## control technologies ; accordingly, the NO x 

## emissions estimation approach accounts for the combined effect of the equipment (Table A4). However, control equipment information is available only for plants that reported on the Form EIA-923 and for historical data from the Form EIA-767. Both the EIA-923 and the historical EIA-767 surveys are limited to plants with boilers fired by combustible fuels 12 

## with a minimum generating capacity of 10 megawatts (nameplate). Pollution control equipment data are unavailable from

12 Boilers that rely entirely on waste heat to create steam, including the heat recovery portion of most combined cycle plants, did not report on the historical Form EIA-767 or EIA-923.

## U.S. Energy Information Administration/Electric Power Annual 2009 92 

## EIA sources for plants that did not report on the historical EIA-767 survey, or the EIA-923. The following method is used to estimate SO 2 

## and NO x 

## emissions:

For steam electric plants , uncontrolled emissions are estimated using the emission factors shown in Tables A1 and A2 as well as reported data on fuel consumption, sulfur content, and boiler firing configuration. Controlled emissions are then determined when pollution control equipment is present. Although information on control equipment was unreported for the years 2006 and 2007, updates for new installations during this period were made based upon Environmental Protection Agency data. For 2008, this data was collected on the Form EIA-923. For SO 2 

## , the reported efficiency of the plant’s FGD units is used to convert uncontrolled to controlled emission estimates. For NO x 

## , the reduction percentages shown in Table A4 are applied to the uncontrolled estimates.

For plants and prime movers not reported on the historical Form EIA-767 survey or EIA-923, uncontrolled emissions are estimated using the Table A1 and Table A2 emission factors and the following data and assumptions:

o Fuel consumption is taken from the Form EIA-923 (for historical data, from the Form EIA-920 - for combined heat and power plants) or the Form EIA-906 - all other power plants).

o The sulfur content of the fuel is estimated from fuel receipts for the plant reported the Form EIA-923 (for historical data, from either the Form EIA-423 or the FERC Form 423). When plant-specific sulfur content data are unavailable, the national average sulfur content for the fuel, computed from the Form EIA-923 (for historical data, from the Form EIA-423 and the FERC Form 423), is applied to the plant.

o As noted earlier, the emission factor for plants with boilers depends in part on the type of combustion system, including whether a boiler is wet-bottom or dry-bottom, and the boiler firing configuration. However, this boiler information is unavailable for steam electric plants that did not report on the historical Form EIA-767 or EIA-860. For these cases, the plant is assumed to have a dry-bottom, non-cyclone boiler using a firing method that falls into the “All Other” category shown on Table A1. 13

13 The “All Other” firing configuration category includes, for example, arch firing and concentric firing. For a full list of firing method options for reporting on the historical Form EIA-767, see the form instructions, page xi, at http://www.eia.gov/cneaf/electricity/forms/eia767/eia767instr.pdf

## o For the plants that did not report on the historical Form EIA-767 or EIA-860, pollution control equipment data are unavailable and the uncontrolled estimates are not reduced.

If actual emissions of SO 2 

## or NO x 

## are reported in EPA’s CEMS data, the EIA estimates are replaced with the CEMS values, using the EIA estimates to allocate the CEMS plant-level data by fuel. If CEMS data are unavailable, the EIA estimates are used as the final values.

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 Btu per barrel. 

# '!0'# 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 of 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 errorsmay be attributed to many sources, including the response errors, definitional difficulties, differences in the interpretation of questions, mistakes in recording or coding data obtained, and other errors of collection, response, or coverage. These nonsampling errors also occur in complete censuses. In a complete census, this problem may become unmanageable. Using the Central Limit Theorem, which applies to sums and means such as are applicable here, there is approximately a 68-percent chance that the true total or mean is within one RSE of the estimated total. Note that reported RSEs are always estimates, themselves, and are usually, as here, reported as percents. As an example, suppose that a net generation from coal value is estimated to be 1,507 total 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). Also under the Central Limit

## Theorem, there is approximately a 95-percent chance that the true mean or total is within 2 RSEs of the estimated mean or total. 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 when 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.

Nonutility power producers consist of entities that own or operate electric generating units but are not subject to direct economic regulation of rates, such as by state utility commissions.. Nonutility power producers do not have a designated franchised service area. In addition to entities whose primary business is the production and sale of electric power, entities with other primary business classifications can and do sell electric power. These can consist of, for example, manufacturing facilities and paper mills. The Energy Information Administration, in the Electric Power Annual and other data products, classifies nonutility power producers into the following categories:

Independent Power Producers (IPPs) whose primary business is selling electricity in the public markets. (The combination of the utility and IPP businesses are referred to by EIA as the Electric Power Sector.)

Power producers whose primary business falls under NAICS 14



## Power producers whose primary business falls under NAICS classifications Transportation and Public (non-electric) Utilities, Wholesale Trade, Retail Trade, Finance, Insurance, and Real Estate are classified as “commercial” producers. classifications Agriculture, Forestry, Fishing, Mining, Construction, or Manufacturing are classified as “industrial” producers.

Each of these non-utility sectors are further divided into facilities which do or do not operate as combined heat and power plants (CHP; often also referred to as co-generators). CHP plants produce heat, such as steam for use in a manufacturing process, along with electricity.

14 Business classifications are based on the North American Industry Classification System (NAICS). 

## The following is a list of the main NAICS classifications and the category of primary business activity within each classification.
