Electricity Monthly Update
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.
