Summary
$6.53 billion in estimated wholesale electricity costs made winter 2025/2026 New England's most expensive since 2014, even as the grid operated reliably and efficiently, the Internal Market Monitor said.
Day-ahead power prices averaged $165.49 per MWh and real-time prices $137.66, with energy market costs rising 51% to $6.08 billion as natural gas prices climbed 31% from a year earlier.
Nineteen straight days below freezing from Jan. 23 to Feb. 10 accounted for nearly 45% of the winter's energy, ancillary services and uplift costs.
Net imports fell from the prior winter because neighboring regions also faced cold weather and higher demand, forcing New England to rely more on natural gas and oil generation.
