State of Charge: The Massachusetts Energy Storage Initiative
By: John R. Wells and Benjamin Weinstock
Abstract
In early 2017, Judith Judson (Harvard Business School MBA, 2000), Commissioner of the Massachusetts Department of Energy Resources (DOER), was reflecting on the results of the initiative she had led to identify the contribution advanced electricity storage could make to electricity generation and distribution in the Commonwealth of Massachusetts. The study was the first major output from the $10 million Energy Storage Initiative (ESI) launched by Massachusetts Governor Charlie Baker’s administration in May 2015. The advanced simulation techniques employed in the study indicated that over a ten-year period, the optimal deployment of storage capacity would cut the cost of electricity for consumers in the Commonwealth by $230 million per year, deliver $110 million in annual revenues for storage providers, and reduce CO2 emissions by 100,000 tons a year, the equivalent of taking 22,000 cars off the road. Moreover, neighboring states would benefit from $250 million in lowered wholesale prices. To deliver these benefits, 1.77 GWh of advanced storage would be required across the grid, costing between $970 million and $1.35 billion. Incorporating the perspectives of a wide body of stakeholders (from utilities to municipalities to generators), the study wound up recommending a suite of policies that would facilitate the installation of 600 MWh of storage capacity by 2025, representing about six minutes of the state’s daily electricity consumption and delivering $800 million in benefits to ratepayers. It would also make the Commonwealth a leader in advanced storage technology and deliver substantial greenhouse gas reductions. At the end of 2015, according to figures from the Department of Energy, Massachusetts ranked 23rd in the United States in energy storage deployment, well behind the leader, Arizona, with nearly 300 MWh, and Texas, with over 150 MWh. However, with advances in storage technology, California promised to become the leader and had plans for nearly 1 GWh of storage capacity over the next five years. The ESI was seeking input on how to spend the balance of its $10 million budget and whether to authorize an additional $10 million on proof-of-concept deployments of the technology. Commissioner Judson pondered. Was this aggressive enough? And where did advanced storage stand in the priorities for the energy future of the Commonwealth?
