Electricity utilities increasingly report using batteries to move electricity from periods of low prices to periods of high prices, a strategy known as arbitrage, according to new detailed information we recently published.

At the end of 2023, electricity utilities in the United States reported operating 575 batteries with a collective capacity of 15,814 megawatts (MW). We expect U.S. battery capacity will more than triple, adding 35,953 MW by the end of 2028 based on plans reported to us by utilities.

We recently published an early release of data from our EIA-860, Annual Electric Generator Report, which includes new detailed information on battery storage applications, including information on use cases, generator configuration, and other details on the energy capacity of planned batteries.

Utilities now report that arbitrage is the primary use

On May 31, Constellation Energy retired the natural gas-fired Mystic Generating Station it owned and operated. Mystic was one of the oldest U.S. electric power plants, located in Charlestown, Massachusetts, on the north side of Boston.

Constellation also owns and operates the adjacent Everett liquefied natural gas (LNG) terminal, which supplied 100% of Mystic’s natural gas. Constellation will keep the Everett terminal open through winter 2029–30 to serve other customers in New England under new six-year supply contracts. Excelerate Energy’s Northeast Gateway, located 13 miles offshore of Massachusetts, can also receive LNG for delivery into New England.

With 1,413 megawatts of combined-cycle gas turbine (CCGT) capacity, Mystic was the largest natural gas-fired power plant operating in the region managed by the Independent System

Note: Data on demand by region lags total demand. ISO-NE=Independent System Operator of New England

Electricity demand in New England surged this week as high temperatures persisted through much of the United States.

Demand in the electric grid territory of New England’s Independent System Operator (ISO-NE) peaked at 23,324 megawatts (MW) during the evening of June 20, approaching last year’s peak hourly demand in this region. The June 20 peak around 7:00 p.m. eastern time was 521 MW above the June 19 peak demand of 22,803 MW, around 6:00 p.m. ISO-NE expects less demand over the weekend and into early next week as temperatures cool.

Peak electricity demand on both June 19 and 20 were a bit less than the
