Electricity Monthly Update
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.
