The largest range of wholesale electricity prices occurred in the Northwest (Mid-C), as this region of the country saw periods of very cold temperatures during February 2025.
Daily peak demand at Southern Company and Bonneville Power Administration were at the top of their 12-month ranges during February 2025.
Total U.S. coal stockpiles decreased by 5.9% to 107 million tons compared to the previous month.
In this section, we look at what electricity costs and how much is purchased. Charges for retail electric service are based primarily on rates approved by state regulators. However, a number of states have allowed retail marketers to compete to serve customers and these competitive retail suppliers offer electricity at a market-based price.
EIA does not directly collect retail electricity rates or prices. However, using data collected on retail sales revenues and volumes, we calculate average retail revenues per kWh as a proxy for retail rates and prices. Retail sales volumes are presented as a proxy for end-use electricity consumption.
Forty-two states and the District of Columbia saw increased revenue per kilowatt-hour (kWh) compared to last February, while average revenue per kWh increased by 3.8% on a national basis. The largest percent increase was in Rhode Island, up 20.6%, followed by Utah, up 18.2%, and Connecticut, up 18.0%. Average revenue per kWh figures decreased in eight states compared to last year. The largest percent decrease was in Nevada, down 14.3%, followed by Hawaii, down 5.0%, and Montana, down 4.6%. In the contiguous US, Rhode Island, Connecticut, and Massachusetts had the highest average revenues at 30.15, 29.15, and 26.36 cents per kWh, respectively. North Dakota, Oklahoma, and Louisiana had the lowest average revenues at 8.25, 8.76, and 8.82 cents per kWh, respectively.

Total average revenues per kilowatt-hour (kWh) increased by 3.8% from last February, to 13.22 cents/kWh in February 2025. All four sectors saw increases in average revenues per kWh compared to last February. The Industrial sector saw the highest increase, up 5.5%, then the Commercial sector, up 3.5%, the Transportation sector, up 2.8%, and finally the Residential sector, up 2.0%. On a nationwide basis, retail sales increased by 5.7% in February 2025 compared to last February, with all four sectors seeing increases. The Transportation sector saw the largest increase in retail sales from last February, up 12.7%, followed by Residential the sector, up 10.1%, then the Commercial sector, up 3.9%, and finally the Industrial sector, up 1.7%.
Forty-two states and the District of Columbia saw an increase in retail sales volume in February 2025 compared to last February. Nebraska had the highest percent year-over-year increase in retail sales, up 20.3%, followed by Oklahoma, up 15.6%, and Montana, up 13.3%. Eight states saw a decrease in retail sales volume compared to last year. Rhode Island had the highest percent year over year decrease, down 20.0%, followed by Alaska, down 5.4%, and Arizona, down 2.8%.

Oklahoma had the highest percent year over year increase, up 74%, followed by Kansas, up 65%, and Missouri, up 62%. Nine states saw a decrease in HDDs from last February. Florida had the highest percent year over year decrease, down 53%, followed by Arizona, down 35%, and Nevada, down 20%.
In this section, we look at the resources used to produce electricity. Generating units are chosen to run primarily on their operating costs, of which fuel costs account for the lion's share. Therefore, we present below, electricity generation output by fuel type and generator type. Since the generator/fuel mix of utilities varies significantly by region, we also present generation output by region.
Net electricity generation in the United States increased 5.7% compared to February 2024. This increase in electricity generation occurred because the country experienced record warm temperatures last February, while the country experienced average temperatures during this February. This led to an increase in electricity generation this February 2025 as the country had more demand for electricity to meet residential heating demand this February compared to February 2024. At the regional level, almost all parts of the country experienced this year-over-year increase in electricity generation. The Western region was the only part of the country that saw a decrease in electricity generation (down 3%) compared to the previous year.
Electricity generation from coal increased in all parts of the country, except for Florida, compared to February 2024. The change in electricity generation from natural gas was more mixed throughout the country, with the Northeast, Southeast, Florida, and Texas all seeing an increase in natural gas generation, while the MidAtlantic, Central, and Western regions all saw a decrease in electricity generation from natural gas compared to the previous February.
The chart above compares coal consumption in February 2024 and February 2025 by region and the second tab compares natural gas consumption by region over the same period. Changes in coal and natural gas consumption were similar to their respective changes in coal and natural gas generation.
The third tab presents the change in the relative share of fossil fuel consumption by fuel type on a percentage basis, calculated using equivalent energy content (Btu). This highlights changes in the relative market shares of coal, natural gas, and petroleum. Most regions of the country saw their share of coal increase at the expense of natural gas. The Northeast also saw its share of other fossil fuels increase at the expense of natural gas. This is not uncommon in the Northeast during the winter months when demand for natural gas increases in an area of the country that has natural gas pipeline constraints. Other fossil fuels, namely petroleum liquids, are used to meet this additional demand for electricity during this time.
The fourth tab presents the change in coal and natural gas consumption on an energy content basis by region. The changes in total coal and natural gas consumption were similar to the changes seen in total coal and natural gas net generation in each region.
To gain some insight into the changing pattern of consumption of fossil fuels over the past year, we look at relative monthly average spot fuel prices. A common way to compare fuel prices is on an equivalent $/MMBtu basis as shown in the chart above. The average price of natural gas at Henry Hub decreased from the previous month, going from $4.62/MMBtu in January 2025 to $4.26/MMBtu in February 2025. The natural gas price for New York City (Transco Zone 6 NY) decreased significantly in price from the previous month, going from $19.26/MMBtu in January 2025 to $6.42/MMBtu in February 2025. The average spot price of Central Appalachian coal went up slightly from the previous month, going from $3.28/MMBtu in January 2025 to $3.30/MMBtu in February 2025.
A fuel price comparison based on equivalent energy content ($/MMBtu) does not reflect differences in energy conversion efficiency (heat rate) among different types of generators. Gas-fired combined-cycle units tend to be more efficient than coal-fired steam units. The second tab shows coal and natural gas prices on an equivalent energy content and efficiency basis. The Henry Hub natural gas price ($34.13/MWh) saw a decrease from the previous month ($36.98/MWh) and was just below the Central Appalachian coal price ($35.60/MWh) in February 2025. The price of natural gas at New York City ($51.39/MWh) saw a significant decrease compared to the previous month ($154.29/MWh) but remained above the Central Appalachian coal price ($35.60/MWh).
The conversion shown in this chart is done for illustrative purposes only. The competition between coal and natural gas to produce electricity is more complex. It involves delivered prices and emission costs, the terms of fuel supply contracts, and the workings of fuel markets.
The United States has many regional wholesale electricity markets. Below we look at monthly and annual ranges of on-peak, daily wholesale prices at selected pricing locations and daily peak demand for selected electricity systems in the Nation. The range of daily prices and demand data is shown for the report month and for the year ending with the report month.
Prices and demand are shown for six Regional Transmission Operator (RTO) markets: ISO New England (ISO-NE), New York ISO (NYISO), PJM Interconnection (PJM), Midwest ISO (MISO), Electric Reliability Council of Texas (ERCOT), and two locations in the California ISO (CAISO). Also shown are wholesale prices at trading hubs in Louisiana (into Entergy), Southwest (Palo Verde) and Northwest (Mid-Columbia). In addition to the RTO systems, peak demand is also shown for the Southern Company, Progress Florida, and the Bonneville Power Authority (BPA). Refer to the map tabs for the locations of the electricity and natural gas pricing hubs and the electric systems for which peak demand ranges are shown.
In the second tab immediately below, we show monthly and annual ranges of on-peak, daily wholesale natural gas prices at selected pricing locations in the United States. The range of daily natural gas prices is shown for the same month and year as the electricity price range chart. Wholesale electricity prices are closely tied to wholesale natural gas prices in all but the center of the country. Therefore, one can often explain current wholesale electricity prices by looking at what is happening with natural gas prices.
Wholesale electricity prices in New York City (NYISO) and New England (ISONE) saw a large range during February 2025, as this part of the country experienced below average temperatures during the month, resulting in spikes in wholesale electricity prices in these regions. Both electricity markets saw their wholesale electricity prices reach lows around $50/MWh and highs just below $200/MWh during February 2025. Texas (ERCOT) was another market that also saw a large range of wholesale electricity prices in February 2025, with this market seeing a low of $14/MWh and high of $163/MWh during the month. However, the largest range of wholesale electricity prices was seen in the Northwest (Mid-C), as this region of the country saw periods of very cold temperatures during February 2025, resulting in electricity prices ranging from a low of $24/MWh to a high of $254/MWh during February 2025.
Wholesale natural gas prices were in fairly tight ranges across most markets in February 2025. New England (Algonquin) was the only part of the country that saw a large range in wholesale natural gas prices during February, mainly due to this area of the country experiencing below average temperatures during a time of year when natural gas pipeline constraints are present. This resulted in New England wholesale natural gas prices ranging from around $4/MMBtu to just above $20/MMBtu during February 2025.
Electricity system daily peak demand varied across the country, with Southern Company and Bonneville Power Administration seeing daily demand at the top of their twelve-month ranges during February 2025. In particular, Bonneville Power Administration almost reached an all-time daily peak demand during February due to periods of extremely cold temperatures during the first half of the month that resulted in increased electricity demand in the region. California (CAISO) was on the opposite end of this spectrum, seeing daily peak demand levels closer to fifty percent of its maximum peak demand during the month.
Total U.S. coal stockpiles decreased by 5.9% to 107 million tons compared to the previous month. This month-over-month decrease in coal stockpiles is normal during the winter months when coal power plants operate more frequently to meet winter electricity demand.
The average number of days of burn held at electric power plants is a forward-looking estimate of coal supply given a power plant's current stockpile and past consumption patterns. For bituminous units largely located in the eastern United States, the average number of days of burn decreased from the previous month, going from 132 days of forward-looking days of burn in January 2025 to 121 days of burn in February 2025. For subbituminous units largely located in the western United States, the average number of days of burn also decreased, going from 147 days of burn in January 2025 to 133 days of burn in February 2025.

The Electricity Monthly Update is prepared by the Electric Power Operations Team, Office of Electricity, Renewables and Uranium Statistics, U.S. Energy Information Administration (EIA), U.S. Department of Energy. Data published in the Electricity Monthly Update are compiled from the following sources: U.S. Energy Information Administration, Form EIA-826,"Monthly Electric Utility Sales and Revenues with State Distributions Report," U.S. Energy Information Administration, Form EIA-923, "Power Plant Operations Report," fuel spot prices from Bloomberg Energy, electric power prices from SNL Energy, electric system demand data from Ventyx Energy Velocity Suite, and weather data and imagery from the National Oceanic and Atmospheric Administration.
The survey data are collected monthly using multiple-attribute cutoff sampling of power plants and electric retailers for the purpose of estimation for various data elements (generation, stocks, revenue, etc.) for various categories, such as geographic regions. (The data elements and categories are "attributes.") The nominal sample sizes are: for the Form EIA-826, approximately 450 electric utilities and other energy service providers; for the Form EIA-923, approximately 1900 plants. Regression-based (i.e., "prediction") methodologies are used to estimate totals from the sample. Essentially complete samples are collected for the Electric Power Monthly (EPM), which includes State-level values. The Electricity Monthly Update is based on an incomplete sample and includes only regional estimates and ranges for state values where applicable. Using "prediction," it is generally possible to make estimates based on the incomplete EPM sample, and still estimate variances.
For complete documentation on EIA monthly electric data collection and estimation, see the Technical Notes PDF to the Electric Power Monthly. Values displayed in the Electric Monthly Update may differ from values published in the Electric Power Monthly due to the additional data collection and data revisions that may occur between the releases of these two publications.
Accessing the data: The data included in most graphics can be downloaded via the "Download the data" icon above the navigation pane.Some missing data are proprietary and non-public.
For a guide that describes electricity data that EIA collects and how the data are made available to the public, see the Guide to EIA Electric Power Data.
The Key Indicators in the table located in the "Highlights" section, are defined below. The current month column includes data for the current month at a national level. The units vary by statistic, but are included in the table. The "% Change from 2010" value is the current month divided by the corresponding month last year (e.g. July 2011 divided by July 2010). This is true for Total Generation, Residential Retail Price, Retail Sales, Degree-Days, Coal Stocks, Coal and Natural Gas Consumption. The Henry Hub current month value is the average weekday price for the current month. The Henry Hub "% Change from 2010" value is the average weekday price of the same month from 2010 divided by the average weekday price of the current month.
The Electric Power Sector comprises electricity-only and combined heat and power (CHP) plants within the North American Industrial Classification System 22 category whose primary business is to sell electricity, or electricity and heat, to the public (i.e., electric utility plants and Independent Power Producers (IPPs), including IPP plants that operate as CHPs). The All Sectors totals include the Electric Power Sector and the Commercial and Industrial Sectors (Commercial and Industrial power producers are primarily CHP plants).
Degree-days are relative measurements of outdoor air temperature used as an index for heating and cooling energy requirements. Heating degree-days are the number of degrees that the daily average temperature falls below 65° F. Cooling degree-days are the number of degrees that the daily average temperature rises above 65° F. The daily average temperature is the mean of the maximum and minimum temperatures in a 24-hour period. For example, a weather station recording an average daily temperature of 40° F would report 25 heating degree-days for that day (and 0 cooling degree-days). If a weather station recorded an average daily temperature of 78° F, cooling degree-days for that station would be 13 (and 0 heating degree days).
The per capita retail sales statistics use 2011 population estimates from the U.S. Census Bureau and monthly data collected by the Energy Information Administration. The volume of electricity delivered to end users for all sectors in kilowatthours is divided by the 2011 population estimate for each state.
Net generation statistics are grouped according to regions (see Electricity Monthly Update Explained Section) by generator type and fuel type. Generator type categories include:
Generation statistics are also displayed by fuel type. These include:
Relative fossil fuel prices are daily averages of fossil fuel prices by month, displayed in dollars per million British thermal units as well as adjusted for operating efficiency at electric power plants to convert to dollars per megawatthour. Average national heat rates for typical operating units for 2010 were used to convert relative fossil fuel prices.
Average Days of Burn is defined as the average number of days remaining until coal stocks reach zero if no further deliveries of coal are made. These data have been calculated using only the population of coal plants present in the monthly Form EIA-923. This includes 1) coal plants that have generators with a primary fuel of bituminous coal (including anthracite) or subbituminous, and 2) are in the Electric Power Sector (as defined in the above "Sector definitions"). Excluded are plants with a primary fuel of lignite or waste coal, mine mouth plants, and out-of-service plants. Coal storage terminals and the related plants that they serve are aggregated into one entity for the calculation of Average Days of Burn, as are plants that share stockpiles.
Average Days of Burn is computed as follows: End of month stocks for the current (data) month, divided by the average burn per day. Average Burn per Day is the average of the three previous years' consumption as reported on the Form EIA-923.
These data are displayed by coal rank and by zone. Each zone has been formed by combining the following Census Divisions:
The coal stocks data presented at the top of the Fossil Fuel Stocks section (“Coal Stocks”) will differ from the coal stocks presented in the Days of Burn section (“DOB Stocks”) at the bottom of the Fossil Fuel Stocks section. This occurs because Coal Stocks include the entire population of coal plants that report on both the annual and monthly Form EIA-923. The DOB Stocks only include coal plants that report on the monthly Form EIA-923 and have a primary fuel of bituminous (including anthracite) or subbituminous as reported on the Form EIA-860.
