As part of the Baker-Polito Administration’s Energy Storage Initiative (“ESI”), the Massachusetts Clean Energy Center (MassCEC) and Department of Energy Resources (DOER) have announced the award of $20 million dollars to support 26 projects for energy storage demonstration projects across the Commonwealth. 

These projects are aimed at piloting innovative, broadly-replicable energy storage use cases/business models with multiple value streams in order to prime Massachusetts for increased commercialization and deployment of storage technologies.

The ACES Program will help direct the Commonwealth’s first substantial investments in energy storage projects that demonstrate the benefits of storage to Massachusetts ratepayers.

This program is currently CLOSED

The ACES Program will provide grants to entities to enable the installation of commercially viable energy storage technologies across a range of use cases, including those identified in the State of Charge report.

Successful applicants will propose projects that demonstrate the multiple benefits of energy storage (including those listed in the State of Charge report), showcase examples of future storage deployment in Massachusetts, help to grow the state’s energy storage economy, and contribute to Massachusetts’ continued clean energy innovation leadership.

MassCEC released a Request for Expressions of Interest survey to potential ACES applicants seeking additional applicant team members. A response to this survey is not required to submit a proposal to the ACES RFP. Responses are posted to the MassCEC website.

For full eligibility criteria, please refer to the ACES solicitation.

This solicitation is now closed. This page is for reference use only.

In 2015, the Baker-Polito Administration announced a two-phase, $10 million dollar Energy Storage Initiative (“ESI”). The ESI aims to advance the energy storage segment of the Massachusetts clean energy industry by expanding storage technology markets, assigning value to storage benefits, accelerating the development of storage technologies, and attracting and supporting energy storage companies throughout the Commonwealth.

In the first phase of this initiative, MassCEC partnered with DOER on an energy storage study – State of Charge - to obtain a broad view of energy storage technologies that will inform future policy and programs.

In the second phase of this initiative, energy storage demonstration projects will be solicited through this ACES RFP with the design of this RFP informed by recommendations from the Study. This RFP aims to fulfill the Administration’s commitment to promote energy storage across the Commonwealth.
