Energy resources such as wind, solar, and energy storage will make up 15.2% of the electricity capacity for New England by 2025.

The operator of the region's power grid, ISO New England, closed on its annual forward capacity auction for 2025-2026, where it works to ensure New England will have enough electricity resources to meet demand, as well as set the clearing price for power, according to a Wednesday announcement from ISO, which is based in Holyoke.

In the auction, ISO secured commitments of 32,810 megawatts of electricity for the upcoming demand in the 2025-2026 season. Of those, 33,356 megawatts comes from existing facilities, while 5,246 megawatts will come from 302 new resources.

Clean energy resources will account for 5,000 megawatts of capacity. That includes solar generation and wind generation, as well as energy storage where solar-generated electricity is stored in a battery until it is needed. Clean energy resources will also come from demand resources where large users of electricity agree to power down their operations when other demand for electricity gets too high.

“New England’s clean energy transition is well underway, and the region’s wholesale markets are playing a vital role by sustaining a reliable power system, maintaining competitive prices, and creating opportunities for the resources that will be the backbone of our clean energy future,” said Robert Ethier, vice president for system planning at ISO New England, in the Wednesday press release.

The preliminary clearing prices set during the auction range from from $2.639 per kilowatt-month to $2.531 kW-month, depending on the pricing zones.
