On June 30, 2017, the Massachusetts Department of Energy Resources (DOER) announced that Massachusetts would adopt an aspirational 200 megawatt-hour (MWh) energy storage target to be achieved by January 1, 2020. The target is the second largest in the nation, although it is far lower than California’s 1.3 gigawatt storage mandate. Still, Massachusetts’ storage target will make the commonwealth a leader in the burgeoning energy storage field.
The process of setting storage targets began last summer, when Massachusetts enacted a law directing DOER to determine whether to set targets for electric companies to procure energy storage systems by January 1, 2020. In September 2016, Massachusetts released a report called the “State of Charge,” which recommended the installation of 600 megawatts (MW) of energy storage by 2025. The report predicted that 600 MW of storage could capture $800 million in system benefits to Massachusetts ratepayers. The energy storage industry praised the 600 MW level as a good starting point.
DOER’s “aspirational” 200 MWh by 2020 target falls short of the “State of Charge” recommendation, but leaves the door open to achieving 600 MW by 2025. DOER’s letter announcing the target noted that “[s]torage procured under this target will serve as a crucial demonstration phase” for Massachusetts to gain knowledge and experience with storage. “Based on lessons learned from this initial target,” the letter continues, “DOER may determine whether to set additional procurement targets beyond January 1, 2020.”
Beyond DOER’s storage target, Massachusetts has a broader Energy Storage Initiative, which includes a $10 million grant program aimed at piloting energy storage use cases and business models in order to increase commercialization and deployment of storage technologies. DOER also announced that it will examine the benefits of amending the Alternative Portfolio Standards, an incentive program for installing alternative energy systems, to expand the eligibility of energy storage technologies able to participate. While Massachusetts’ storage targets are not as lofty as some in the industry were hoping, the commonwealth is demonstrating a clear commitment to developing its energy storage industry beyond the few megawatts currently installed.
