ISO-NE issues winter update to Wholesale Markets Project Plan

ISO New England has published the latest edition of its Wholesale Markets Project Plan (WMPP). The plan lists the status of 13 markets-related projects as of December 2025, including five new projects added since the last edition in June 2025. Published every winter and summer, the WMPP is a companion piece to the ISO’s Annual Work Plan, which is published in the spring and fall.

The ISO undertakes many projects and initiatives for the continued development of the region’s wholesale electricity markets.

The most significant current project continues to be Capacity Auction Reforms (CAR), which will transition the capacity market to a prompt and seasonal market with capacity accreditation and resource deactivation reforms. The stakeholder process recently concluded for the first phase of this project, with stakeholder discussions on the second phase now underway.

Stakeholders can follow market projects from introduction to implementation on the WMPP webpage, which consolidates access to the Annual Work Plan, WMPP, key projects, a listing of completed market design projects, the NEPOOL Markets Committee Two-Month Look-Ahead Forecast, and Markets Committee meeting agendas and materials.

Quick links to Federal Energy Regulatory Commission filings and orders, as well as the ISO’s Participant Readiness Project Outlook page, are also available to further inform and support market participants and others looking to track market-related projects.
