Massachusetts' Gap Energy Grant Program

Bringing energy-saving results to Massachusetts’ communities through efficiency and clean energy generation upgrades.

Introduction

The 2026 Gap IV Energy Grant awards $8.7 Million to 34 Municipal Water Facilities and Food and Agricultural Nonprofits and Small Businesses 

Under the leadership of MassDEP, the Clean Energy Results Program (CERP) is an integrated energy and environmental partnership with the Massachusetts Department of Energy Resources (DOER) and the Massachusetts Clean Energy Center (MassCEC) that reduces regulatory or other barriers to clean and energy efficient development across the state.  The Gap Grant is a cornerstone of this partnership and is a streamlined energy grant funding model that has helped municipal water utilities reduce their energy usage, operating costs, and improve the environment. The grant is designed to fill the last “gap” in project financing, enabling and encouraging facilities to use energy utility incentives as well as funding from other sources to install selected energy efficiency and clean energy generation projects. In the 2022-2023 round, the Gap III Energy Grant expanded its eligibility to include nonprofit multifamily affordable housing organizations, nonprofit agricultural food producing organizations, and small businesses engaged in food distribution and processing.
