The Massachusetts Legislature has passed a sweeping energy bill that solidifies the state’s position as a national leader in clean energy development. A key piece of the legislation requires utilities to obtain contracts for 1.6 gigawatts of offshore wind energy generation by mid-2027. Another part of the bill requires utilities to procure an as yet undetermined amount of energy from storage technologies by 2020. If signed into law by the governor, Massachusetts would become the third state to create an energy storage mandate, joining California and Oregon. The storage requirements are expected to help Massachusetts add resiliency to its rapid integration of renewable energy capacity. As of May, Massachusetts had about 40,000 distributed solar projects, and the state is adding about 400 distributed new installations a week.
