• 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.

    Program Goals

    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 will include a study, a market signals assessment, 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(a) of the Act states that, “on or before December 31, 2016, the department of energy resources shall determine whether to set appropriate targets for electric companies to procure viable and cost-effective energy storage systems to be achieved by January 1, 2020.” 

    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, DOER has determined that it is prudent for the Commonwealth to set targets for energy storage systems.

    The Act further allows DOER to consider, “…a variety of policies to encourage the cost-effective deployment of energy storage systems…” and therefore the department will immediately commence an additional public comment period, open until January 27, 2017. In structuring feedback, we ask stakeholders to consider the appropriate target scale, structure, and mechanisms for the energy storage systems targets.

    Written response must be submitted to Storage.DOER@massmail.state.ma.us on or before 5:00PM on January 27, 2017. Please note that any submission may be made publicly available.

    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 are due by 4:00 PM EST on June 09, 2017

    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.

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