• 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.

    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

    Program Goals

    The goal for the Energy Storage Initiative is to advance 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 will include a study, a market signals assessment, and demonstration projects.

    Energy Storage 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 pdf format of MassCEC DOER Webinar 2015-12-15 Presentation

    ESI Demonstration Program Advancing Commonwealth Energy Storage

    DOER and MassCEC will be opening a 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.

    ESI ACES Program RFP Development Stakeholder Survey

    DOER and MassCEC created and circulated a survey in early August 2016 to inform decision-making about the core components of the program Request for Proposals (RFP). Responses to this survey were due by August 19, and participation does not affect selection of applications during the RFP process.

    ESI ACES Program Request for Expressions of Interest

    DOER and MassCEC are currently seeking expressions of interest (EOI) from entities who will be interested in applying for ACES funding. The information submitted in these responses may be made publicly available on the MassCEC website to help facilitate formation of ACES RFP applicant teams. Team members do not have to fill out an expression of interest to be eligible for program funding.

    Future Opportunities

    The program approach outlined above identifies Massachusetts’ initial steps in creating what participants hope will be a robust energy storage market that will serve ratepayers and grid resiliency going forward. DOER plans to continue to work with all of its stakeholders to develop future opportunities.
