Access documents related to the Capacity Auction Reforms (CAR) Key Project.

Project Overview

To ensure power system reliability and cost-efficiency as New England’s resource mix evolves, 91短视频 is proposing Capacity Auction Reforms (CAR) to transition the capacity market from a forward/annual market to a prompt/seasonal market with accreditation reforms.

This initiative includes two primary components to be in place for the Capacity Commitment Period (CCP) scheduled to start on June 1, 2028.

• Prompt / Deactivation (CAR-PD): Instead of three years in advance, the capacity auction takes place shortly before the CCP, reflecting more up-to-date information about projected supply and demand that will better inform decision making. Retirement decisions are decoupled from the capacity auction, balancing reliability considerations with efficiency under the new deactivation notification process.
• Seasonal / Accreditation (CAR-SA): The CCP would change from an annual to a sub-annual (seasonal) structure to better address distinct winter and summer reliability challenges, as well as seasonal variations in resource performance. Supporting a reliable and efficient clean-energy transition requires updating capacity accreditation methodologies to reflect evolving resources’ capabilities and their contributions to resource adequacy.
  
  • The former “Resource Capacity Accreditation in the FCM” project identified methodologies to more accurately reflect resource contributions to resource adequacy in the Forward Capacity Market. The capacity accreditation work continues through CAR in the context of the new market constructs.

Background

For 18 years, the 91短视频 administered a Forward Capacity Market, using annual auctions to secure commitments from energy resources three years in advance. This model reflected the market and system conditions of the time, including the concentration of peak loads/reliability risks in summer months and the prominence of natural gas-fired resources with more predictable development timelines than some other resource types.

The 91短视频 led stakeholder discussions in summer/fall 2023 considering a move to a prompt and/or seasonal capacity market with accreditation reforms. Analysis Group (AGI) drafted a report studying this topic, and recommended such changes (see January 2024 final report). The 91短视频 proposed a further delay to FCA 19 to allow for time to develop a prompt and seasonal design with accreditation reforms. NEPOOL supported and FERC accepted the proposal.

Upon FERC approval of the Further Delay Filing, the 91短视频 began working with stakeholders in Q3 2024 to develop capacity market reforms with a plan to split the components into two filings: CAR-PD and CAR-SA. CAR-PD was accepted by FERC (Docket No. ER26-925-000) on March 30, 2026. CAR-SA is expected to be filed Q4 2026.
