PJM power auction results yield dramatically greater prices

A yearly power market auction by the biggest U.S. electrical grid operator resulted in prices more than 800% greater than in 2015 as supply diminished and need increased, the operator stated on Tuesday.

PJM Interconnection, which covers parts of 13 states from Illinois to New Jersey, exposed the outcomes of its 2025 to 2026 capacity auction. Rates for power plants landed at $269.92 per megawatt-day, compared to $28.92 per megawatt-day for year-ago auction, the grid operator said in a statement.

The substantially higher rates in this auction confirm our concerns that the supply/demand balance is tightening up, stated PJM President Manu Asthana stated. The marketplace is sending a cost signal that should incent investment in resources.

The auction secured 135,684 megawatts for the period from June 1, 2025, through May 31, 2026. The power mix from generators included 48% gas, 21% nuclear, 18% of coal, 1% of solar, 1% of wind, 4% of hydro, 5% of demand response and 2%. from other resources, PJM said.
