End Use: June 2026

Retail rates/prices and consumption

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.

Average revenue per kWh by state

Forty-three states and the District of Columbia saw increased revenue per kilowatt-hour (kWh) compared to last June, while average revenue per kWh increased by 4.5% on a national basis. The largest percent increase was in Hawaii, up 35.5%, followed by Delaware, up 13.5%, and the District of Columbia, also up 13.5%. Average revenue per kWh figures decreased in 7 states compared to last year. The largest percent decrease was in Connecticut, down 9.7%, followed by New Mexico, down 8.9%, and West Virginia, down 3.9%. In the contiguous US, California, Massachusetts, and Rhode Island had the highest average revenues at 28.50, 25.72, and 25.30 cents per kWh, respectively. New Mexico, North Dakota, and Wyoming had the lowest average revenues at 8.96, 9.01, and 10.10 cents per kWh, respectively.

Total average revenues per kilowatt-hour (kWh) increased by 4.5% from last June, to 14.48 cents/kWh in June 2026. All four sectors saw increases in average revenues per kWh compared to last June. The transportation sector saw the highest increase, up 8.8%, then the residential sector, up 5.0%, the commercial sector, up 4.8%, and finally the industrial sector, up 3.0%. On a nationwide basis, retail sales increased by 1.5% in June 2026 compared to last June. The commercial sector saw the largest increase in retail sales from last June, up 3.4%, followed by the industrial sector, up 1.3%. The residential and transportation sectors each saw a decrease in retail sales, down 0.2% and down 11.9%, respectively.

Retail sales

Thirty-eight states saw an increase in retail sales volume in June 2026 compared to last June. Arizona had the highest percent year over year increase in retail sales, up 9.2%, followed by Nebraska, up 7.9%, and New Mexico, up 7.0%. Twelve states and the District of Columbia saw a decrease in retail sales volume compared to last year. Rhode Island had the highest percent year over year decrease, down 15.4%, followed by Illinois, down 6.2%, and the District of Columbia, down 5.6%.

Thirty-eight states saw a decrease in CDDs from last June. Montana had the highest percent year over year decrease, down 74%, followed by Alaska, down 67%, and Vermont, down 46%. Nine states and the District of Columbia saw an increase in CDDs compared to last June. New Mexico had the highest percent year over year increase, up 13%, followed by Colorado, up 10%, and Oklahoma, up 10%.

Resource Use: June 2026

Supply and fuel consumption

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.

Generation output by region

Net electricity generation in the United States increased 1.6% compared to June 2025. The changes in electricity generation from the previous June were mixed throughout the country. The West, Texas, Southeast, and Florida all saw a year-over-year increase in electricity generation, while the Central, Mid-Atlantic, and Northeast regions saw a decrease in electricity generation when compared to the previous year. The decrease in electricity generation in the Central, Mid-Atlantic, and Northeast regions was generally a result of cooler conditions in June 2026 compared to June 2025, which reduced electricity demand in those regions.

Electricity generation from coal saw year-over-year decreases in all regions except Florida. Most regions saw a decrease in natural gas generation compared to June 2025, with the exception of Texas, the Southeast, and Florida, where natural gas generation increased compared to the previous June. All regions saw year-over-year increases in electricity generation from other renewable sources.

Fossil fuel consumption by region

The chart above compares coal consumption in June 2026 and June 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. The West, Texas, Southeast, Central, and Mid-Atlantic regions all saw their share of coal decrease at the expense of natural gas. No regions saw a meaningful shift from natural gas to coal.

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.

Fossil fuel prices

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 increased from the previous month, going from $2.92/MMBtu in May 2026 to $3.15/MMBtu in June 2026. The natural gas price for New York City (Transco Zone 6 NY) also increased from the previous month, going from $2.08/MMBtu in May 2026 to $2.39/MMBtu in June 2026. The average spot price of Central Appalachian coal decreased from the previous month, going from $3.48/MMBtu in May 2026 to $3.28/MMBtu in June 2026.

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 ($25.19/MWh) saw an increase from the previous month ($23.43/MWh) and was below the Central Appalachian coal price ($35.42/MWh) in June 2026. The price of natural gas at New York City ($19.14/MWh) also saw an increase compared to the previous month ($16.62/MWh) and was also below the Central Appalachian coal price ($35.42/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.

Regional Wholesale Markets: June 2026

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 prices

Wholesale electricity prices were near the lower end of their yearly ranges at most regional trading hubs in June 2026. New York City, Louisiana, Southern California, Northern California, and Northwest prices all came close to, but did not quite reach, their lowest prices of the twelve-month period ending June 30. Mid-Atlantic (PJM) prices showed the widest monthly range of any hub, ranging from $36/MWh to $216/MWh during June 2026, while Midwest (MISO) prices also saw a notably wide spread, ranging from $25/MWh to $110/MWh.

Wholesale natural gas prices traded in tight ranges across most markets in June 2026. Southern California (SoCal Citygate) and Southwest (El Paso San Juan) prices showed the widest monthly swings of any market, with Southern California prices ranging from around $1.35/MMBtu to $3.36/MMBtu and Southwest prices ranging from around $1.15/MMBtu to $2.96/MMBtu during the month. Henry Hub and Chicago prices were particularly steady, each trading in ranges of less than $0.40/MMBtu.

Electricity system daily peak demand

Most of the country saw elevated peak electricity demand during June 2026, with daily peak demand reaching the upper end of twelve-month ranges across many trading hubs. Specifically, the Mid-Atlantic (PJM), Midwest (MISO), Southern Company, and Texas (ERCOT) all saw their daily peak demand approach or reach the top of their twelve-month ranges, particularly toward the end of the month, with the Midwest (MISO) reaching its highest daily peak demand of the past twelve months on the last day of June.

Electric Power Sector Coal Stocks: June 2026

Total U.S. coal stockpiles decreased by 1.4% to 118 million tons compared to the previous month. This month-over-month decrease in coal stockpiles is normal as the country enters the summer months when coal power plants operate more and use up their stockpiles to meet summer electricity demand.

Days of burn

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 increased from the previous month, going from 101 days of forward-looking days of burn in May 2026 to 117 days of burn in June 2026. For subbituminous units largely located in the western United States, the average number of days of burn also increased, going from 114 days of burn in May 2026 to 116 days of burn in June 2026.

Methodology and Documentation

General

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.

Key Indicators

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.

• Total Net Generation:  Reflects the total electric net generation for all reporting sectors as collected via the Form EIA-923.
• Residential Retail Price:  Reflects the average retail price as collected via the Form EIA-826.
• Retail Sales:  Reflects the reported volume of electricity delivered as collected via the Form EIA-826.

Sector Definitions

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

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).

Per Capita Retail Sales

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.

Composition of Fuel Categories

Net generation statistics are grouped according to regions (see Electricity Monthly Update Explained Section) by generator type and fuel type. Generator type categories include:

• Fossil Steam:  Steam turbines powered by the combustion of fossil fuels
• Combined Cycle:  Combined cycle generation powered by natural gas, petroluem, landfill gas, or other miscellaneous energy sources
• Other Fossil:  Simple cycle gas turbines, internal combustion turbines, and other fossil-powered technology
• Nuclear Steam:  Steam turbines at operating nuclear power plants
• Hydroelectric:  Conventional hydroelectric turbines
• Wind:  Wind turbines
• Other renewables: All other generation from renewable sources such as geothermal, solar, or biomass
• Other:  Any other generation technology, including hydroelectric pumped storage

Generation statistics are also displayed by fuel type. These include:

• Coal:  all generation associated with the consumption of coal
• Natural Gas:  all generation associated with the consumption of natural gas
• Nuclear:  all generation associated with nuclear power plants
• Hydroelectric:  all generation associated with conventional hydroelectric turbines
• Other Renewable: all generation associated with wind, solar, biomass, and geothermal energy sources
• Other Fossil: all generation associated with petroleum products and fossil-dervied fuels
• Other:  all other energy sources including waste heat, hydroelectric pumped storage, other reported sources

Relative Fossil Fuel Prices

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

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:

• Northeast — New England, Middle Atlantic
• South — South Atlantic, East South Central
• Midwest — West North Central, East North Central
• West — Mountain, West South Central, Pacific Contiguous

Coal Stocks vs. Days of Burn Stocks

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.
