On April 30, 2024, Senators Markey, Sanders, Warren, and Whitehouse sent a letter to ISO-NE President and CEO Gordon van Welie urging the independent system operator to improve its governance policies, proactively plan for new transmission, and ensure fair access to markets for clean energy technologies. The letter advocated for several changes that Policy Integrity has pushed in the past, including increasing opportunities for community participation in energy policy decisions and pursuing longer-term, holistic transmission planning. On the latter point, the letter cited our December 2023 report that advocated for more proactive transmission planning on the part of energy decisionmakers.
