On September 1, 2022, five New England states—Massachusetts, New Hampshire, Connecticut, Rhode Island, and Maine— launched an effort to help connect offshore wind projects and other carbon-free resources to the power grid over the next three decades.[1] In a joint request for information (RFI), the states requested comments on how to limit the costs of transmission for consumers, where new power lines should be located, and how environmental justice and equity impacts should be considered. The states hope to speed up the process for building new power lines and related infrastructure and to make use of funding programs established by the Bipartisan Infrastructure Law (BIL). Although Vermont, the only state in New England without a coastline, is not participating in the joint initiative, it will remain an observer and supports the objectives of the initiative.

Currently, the New England states have about 8.3 GW of offshore wind under construction or in the permitting process. However, the RFI cited a 2020 study conducted by ISO New England (ISO-NE) that indicated the region could only add up to 5.8 GW of offshore wind without major new transmission reinforcements on land. “Any significant quantity of offshore wind beyond that amount may not be able to interconnect into the regional grid without significant transmission upgrades,” the RFI said. “In addition, the most easily accessible interconnection points along the southern New England coast are already at or beyond their full capacity with those offshore wind projects under contract or review.” Comments on the RFI are due October 14, 2022.
