The Massachusetts DPU cleared the way for two major battery facilities that would have a combined rating of 400 MW/800MWh, which is most of the state's 1,000-MW target for 2025.

The agency determined that it lacks jurisdiction over battery energy storage systems, referring such projects to the state's Department of Public Utilities.

Alternatives to the new Mass. LNG facility, such as expanding interstate natural gas pipelines, are more harmful to the environment, EFSB's Andre Gibeau said.

Clean energy advocates are pushing Massachusetts regulators to reconsider their tentative approval of an LNG facility near an environmental justice community.
