Consistently cold weather drove record-high December energy market costs for ISO-NE and caused the region to rely heavily on stored oil and LNG injections.

ISO-NE’s probabilistic modeling indicates there is minimal risk of shortfall in the upcoming winter, COO Vamsi Chadalavada told the NEPOOL Participants Committee.

ISO-NE received six proposals from four different companies in response to its request for proposals to address transmission constraints and interconnect onshore wind in Maine.

The New England wholesale electricity markets performed competitively in 2024, while decreased imports and higher emissions compliance rates increased overall market costs, the ISO-NE Internal Market Monitor told the NEPOOL Participants Committee.

Pay-for-Performance credits accumulated during capacity scarcity conditions June 24 totaled about $114 million, ISO-NE's COO told the NEPOOL Participants Committee.

The NEPOOL Participants Committee voted to support an expedited filing adjusting several key dates in ISO-NE’s compliance proposal for FERC Order 2023.

In an appearance before the NEPOOL Participants Committee, ISO-NE CEO Gordon van Welie discussed his recent testimony at the U.S. House Energy and Commerce Subcommittee on Energy.

New England energy market revenues increased by roughly 150% in the winter of 2024/25 compared to the prior winter.

ISO-NE’s total energy market value reached about $1 billion in December — more than double the total value of the market in December 2024 — due to lower temperatures and increased natural gas prices.
