Technical FAQs 4

How much energy storage does Massachusetts have?

The act requires all electric distribution companies (EDCs) to report annually on energy storage deployment within their territories no later than February 15 each year. It was reported last year that Massachusetts had a cumulative storage capacity of 569MWh, with an additional 8,806 MWh in the development pipeline.

What is Massachusetts' energy storage policy?

Like other states that are leading the energy storage policy development effort, the Massachusetts Legislature has been a primary vehicle for defining high-level goals and guidelines. The primary purpose of H. 4568 was to require utilities to competitively solicit and contract for approximately 1,200 MW of clean energy generation.

What incentives are available for energy storage in Massachusetts?

Along with the SMART program, Massachusetts has several incentive funding mechanisms that are aimed at unlocking the full potential of energy storage, either as a stand-alone resource or as a hybrid resource with renewables (e.g., solar + storage).

What is Flatiron Energy's 300 MW battery storage project?
