The Problem Nobody Explains
Mass Save is one of the best home energy rebate programs in America. Homeowners can get $5,000–$10,000 rebates for heat pumps. But if you live in one of 41 towns, you're locked out. Completely.
These 41 towns have their own electric utility—called a Municipal Light Plant (MLP). It's town-owned, not run by the big utility companies. Because of that, Mass Save won't serve them.
Nobody selling heat pumps tells you this until you've already spent time getting quotes.

Why Are They Locked Out?
Mass Save gets its funding from the big utility companies: National Grid, Eversource, Unitil. Towns with their own MLPs don't have those companies funding rebates. So Mass Save can't help them.
It's not about income or eligibility. It's geography. If your town's electric company is town-owned, you're out of luck with Mass Save.
What Can You Do Instead?
You have three paths:
Path 1: Your Town's Own Program
Many MLPs run their own rebate programs. They're usually smaller than Mass Save. But they can help.
Call your town's municipal light department. Ask: "Do you have a heat pump rebate program?" Some do. Some don't. It varies by town.
Path 2: The Municipal Light Plant Zero-Interest Loan
Massachusetts has a state program specifically for MLP towns. It's a zero-interest loan up to $25,000. You borrow the money, then the energy savings pay back the loan over time.
Example: You borrow $8,000 for a heat pump. Your energy bill drops $1,200/year. The loan is paid back in about 7 years. After that, 20+ years of free heating.
Path 3: Federal & State Options
You might qualify for:
- Federal Rebates: The Inflation Reduction Act created tax credits for heat pumps, solar, and batteries. Check if you're eligible at fuelcellsanhydrogen.energy.gov.
- State Clean Energy Program: Some state programs serve all Massachusetts towns. Call the Massachusetts Clean Energy Center for options.
- No-Cost or Low-Cost Audits: Even without Mass Save, you can get a free energy audit to see where you're losing money.
The Actual Numbers (MLP Towns vs Mass Save Towns)
With Mass Save (Boston, Worcester, Springfield, etc.):
- Heat pump install cost: $6,000–$10,000
- Mass Save rebate: $5,000–$10,000
- You pay: $0–$5,000
- Payback: 3–5 years
Without Mass Save (Concord, Wellesley, etc., using zero-interest loan):
- Heat pump install cost: $6,000–$10,000
- You borrow: Full amount (interest-free)
- Energy savings pay loan back: 6–8 years
- Then 20+ years of free heating
Bottom Line
Living in one of 41 MLP towns means Mass Save isn't available. But it's not the end of the road. You have options, and they're not terrible.
Call your town's municipal light department and ask about their programs. Then explore the zero-interest loan. A heat pump still makes financial sense—it just takes a bit longer to pay for itself.
