New England Electric Prices 48% Higher in 2025 from Lack of Pipes

ISO New England’s Internal Market Monitor reported that total wholesale electricity costs in New England reached $15 billion in 2025, up 48% from 2024. The increase was driven by higher natural gas prices, tighter supply, changes in the resource mix, and shifts in market design. Day-ahead energy prices averaged $71.81/MWh, up 73%, while real-time prices rose 67% to $65.89/MWh. Natural gas prices more than doubled to $6.27/MMBtu. Carbon taxes added $1.1 billion to energy costs. Boiling it all down, aside from carbon taxes, high natgas prices are the main culprit. The report (full copy below) has some thoughts about why natgas prices are so high in New England.
