Energy storage can provide significant benefits for the energy grid, renewable energy generators, ratepayers and the Massachusetts economy. Energy storage technologies have massive market potential in the Commonwealth, U.S. and global markets and the Energy Storage Initiative aims to make Massachusetts a national leader in the deployment and effective use of these innovative energy technology solutions.
The Baker Administration launched the Energy Storage Initiative in May 2015, with the goal of advancing the energy storage segment of the Massachusetts clean energy industry by:
- Attracting, supporting and promoting storage companies in Massachusetts
- Accelerating the development of early commercial storage technologies
- Expanding markets for storage technologies, and valuing storage benefits to clean energy integration, grid reliability, system wide efficiency, and peak demand reduction
- Recommending and developing policies, regulations and programs that help achieve those objectives.
The ESI aims to find the most cost efficient and effective way to help transform the market. The Department of Energy Resources (DOER) will utilize the $10 million allocation from the 2014 Alternative Compliance Payment (ACP) Spending Plan for energy storage to pursue a multi-pronged approach to establish an energy storage market structure as well as build strategic partnerships and support storage projects at the utility, distribution system, and customer side scale.
The ESI includes a study and demonstration projects.
Energy Storage Target
On August 8, 2016, An Act Relative to Energy Diversity, Chapter 188 of the Acts of 2016 (“Act”), was signed into law by Governor Baker. Section 15(b) of the Act states that, “The department shall adopt the procurement targets, if determined to be appropriate 736 under subsection (a), by July 1, 2017.”
As part of this determination process, the Department of Energy Resources (DOER) solicited written stakeholder input addressing whether Massachusetts should adopt targets for energy storage systems. After careful review and consideration of the comments received, as well as research and analysis in line with the department’s State of Charge energy storage study, DOER has determined that the appropriate next step for the Commonwealth is the adoption of an aspirational 200 Megawatt hour (MWh) energy storage target for electric distribution companies to procure viable and cost-effective energy storage systems to be achieved by January 1, 2020.
The Act further requires that each electric distribution company submit a report to DOER no later than January 1, 2020 detailing how they have complied with the energy storage target set by the department. To better understand the achievement of the target, DOER has asked that the electric distribution companies submit annual reports beginning on January 1, 2018. DOER has requested that the reports include information on the amount of energy storage procured by each company, the cost-effectiveness of the energy storage projects undertaken, how wholesale market opportunities were identified and monetized, and for any recommendations for programs and policies to ensure the continued cost-effective deployment of energy storage. Based on lessons learned from this initial target, DOER will determine whether to set additional procurement targets beyond January 1, 2020.

ESI Demonstration Program Advancing Commonwealth Energy Storage
DOER and MassCEC have an open request for proposals for energy storage demonstration projects over a range of application scales – utility, distribution system and behind the meter (BTM) – in Massachusetts. Successful applicants will propose projects that address the unique needs and barriers to storage deployment in Massachusetts, help to grow the state's energy storage economy, and contribute to Massachusetts' continued clean energy innovation leadership.
The opportunity can be found at the MassCEC Website
Proposals were due by 4:00 PM EST on June 09, 2017

Energy Storage Study
DOER partnered with the Massachusetts Clean Energy Center (MassCEC) to develop State of Charge, a comprehensive Energy Storage Study

Key findings of the study include:
- Ratepayer cost benefits of energy storage associated with reduced peak demand, deferred transmission and distribution investments, reduced GHG emissions, reduced cost of renewables integration, deferred new capacity investments, and increased grid flexibility reliability and resiliency
- Identification and economic evaluation of energy storage use cases
- Identification of current barriers to energy storage adoption in the Commonwealth
- Policy and program recommendations to properly value energy storage
- Near and long term economic and workforce benefits to Massachusetts by implementing energy storage
Energy Storage Study Stakeholder Input Process
On October 30, 2015, the energy consultant team conducting the Energy Storage Study held an energy storage stakeholders meeting to identify and evaluate the appropriate value of the services energy storage can provide to ratepayers and the grid.
Presentations from the October 30 Stakeholder Workshop can be downloaded here:
Notes for each of the four breakout groups are available here:
- Wholesale Markets/Transmission - Link
- Utility Applications – Distribution - Link
- Behind-the-Meter/DER - Link
- Energy Storage Technology Developers - Link
On December 15, 2015, the energy consultant team held an Energy Stakeholder Update Webinar to provide an update on the progress of the Energy Storage Study. The presentation from the webinar can be downloaded here: ESI Webinar file size 1MB
On September 27, 2016, the State of Charge Study findings were publicly presented with opportunities for stakeholder questions.
