Massachusetts’ new Office of Energy Transformation will focus on cutting peaker plant emissions, eliminating the state’s reliance on the Everett Marine Terminal LNG import facility, and financing distribution grid upgrades that minimizes costs.

The six New England states have submitted two applications for federal funding for transmission projects aimed at improving grid reliability and enabling the interconnection of clean energy resources.
