DOER PON-ENE-2023-017 Low- and Moderate-Income Housing Decarbonization Grant Program Amendment

The Commonwealth of Massachusetts Department of Energy Resources (DOER) is offering a grant program to fund decarbonization retrofits of existing low‑ and moderate‑income residential housing. Eligible projects may receive up to $50 M in total grant funding from a combination of ARPA, DOER Alternative Compliance Payments, and the DEP Climate Protection & Mitigation Trust. Grants support energy‑efficiency upgrades, electrification of heating/cooling/hot‑water/cooking systems, on‑site solar PV, and removal of barriers such as asbestos or outdated electrical infrastructure. Funding is awarded on a rolling‑basis in defined evaluation batches, with strict affordability commitments and a requirement that projects remain fully funded by 30 Jun 2027. Applications must include detailed project narratives, budgets, and supporting documentation, and are scored on qualifications, technical scope, benefits, management plan, and cost‑effectiveness. • Eligible applicants: private firms, non‑profits, municipalities, or other public entities located in Massachusetts; must serve low‑ or moderate‑income households (≤ 99 % of state median income). • Funding limits: minimum grant $240 k; per‑unit caps of $50 k (≤ 5 units) or $40 k (≥ 6 units). Larger projects may receive higher discretionary amounts. • Disbursement: milestone‑based reimbursements; no upfront lump‑sum. Matching funds may include ARPA dollars; other non‑federal sources are encouraged.
