Why Massachusetts Homeowners Pay So Much for Energy (And What You Can Do About It)

Massachusetts consistently ranks among the most expensive states in the nation for electricity. In 2026, the average residential electricity rate hovers between 25 and 30 cents per kWh — nearly double the national average. Add in the cost of heating oil, propane, or natural gas through a long MA winter, and the average Massachusetts household can spend $3,000 to $5,000 or more per year on home energy.

The culprit is a mix of aging housing stock, cold-climate heating demands, and regional grid constraints. The solution, increasingly, is a combination of home efficiency upgrades and clean energy generation — and the state of Massachusetts, along with utilities like Eversource and National Grid, is actively paying homeowners to make those upgrades happen.

What Is Mass Save? The Foundation of MA Energy Efficiency

If you’ve lived in Massachusetts for any length of time, you’ve probably heard of Mass Save. But many homeowners still don’t fully understand what it is, who runs it, or how to take advantage of it.

Mass Save is a statewide energy efficiency program administered by Massachusetts’ major electric and gas utilities — including Eversource and National Grid — along with other partners. It’s funded through a small charge on all utility customers’ bills, and it exists specifically to help Massachusetts residents reduce their energy consumption and costs.

In plain terms: Mass Save rebates in 2026 can put real money back in your pocket when you upgrade your home’s insulation, heating, cooling, water heating, and more. You don’t need special income qualifications for most programs — if you’re a Massachusetts homeowner served by a participating utility, you’re likely eligible.
