Learn · Incentives by State
The real 2026 state and utility incentives for solar, battery storage, heat pumps, and EV charging. What they pay, who they're for, and how they stack — in plain English.
Whole-home electrification — typical stack
No federal tax credits assumed. Real numbers depend on equipment, contractor, and income tier.
State · SMART Program
~$0.04–$0.08 / kWh
paid for 10 years
Compensation for each kWh your solar produces. Rate varies by utility territory and system tier. Worth roughly $4k–$8k present value on a typical 8–10 kW residential system.
State · Net Metering
1:1 credit
on excess generation
Solar that you don't use in real time gets credited at the full retail rate against your future bills. The single most valuable solar policy in the state.
Utility · ConnectedSolutions
~$225 / kW-summer
per year, 5-year enrollment
National Grid and Eversource pay you to let them call on your battery during peak hours in summer. A 10 kW battery can earn ~$2k+ per year, often ~$10k+ over 5 years.
State · SMART Adder
Adder rate
added to SMART payments
If you pair a battery with a SMART-enrolled solar system, you get a per-kWh adder for the life of the contract. Modest but real — typically $1–$3k present value.
Utility · Mass Save
Up to $10,000
when fully displacing fossil heat
The richest residential heat pump rebate in the country. You must take your fossil fuel system offline. Income-tiered enhancements available up to 100% project cost for qualifying households.
Utility · Mass Save
$1,250 / ton
up to $3,750
For partial-displacement installs (e.g., adding heat pumps but keeping the boiler as backup). Smaller, but easier to qualify for and stack with weatherization rebates.
Utility · EV Make-Ready
Up to $700
per residential Level 2 charger
National Grid and Eversource both run residential EV charger programs covering the charger and panel work, depending on territory and equipment list.
State · Net Metering
~Retail credit
below 100 kW systems
Residential systems credit at the full energy charge plus a portion of distribution. Less generous than MA, but still the main lever in NH solar economics.
Utility · Battery Storage Pilot
$/kW dispatched
utility-by-utility rates
NH utilities run battery dispatch pilots similar to ConnectedSolutions. Smaller payouts than MA but real revenue — typical 10 kWh battery earns several hundred dollars per year.
Utility · NHSaves
$500–$2,000+
per qualifying outdoor unit
NHSaves rebates scale by unit efficiency tier and zone count. Income-tier enhancements available. Smaller than Mass Save but a real chunk of the install cost.
State · Net Metering
Retail + ~$.04 adder
on excess generation
Vermont net metering compensates excess solar at retail plus a renewable-energy adder. Strongest residential solar policy in northern New England.
State · Efficiency Vermont
$350–$2,500
per heating zone
Efficiency Vermont rebates are tied to unit performance at low temperatures. Multi-zone installs can stack rebates per outdoor unit — a 3-zone install often earns $4–$6k.
State · Efficiency Vermont
Up to $4,000
on whole-home weatherization
VT is unusual in how aggressively it pays for insulation and air sealing. Worth doing before sizing a heat pump — a tighter house needs less heat.
State · Net Energy Billing
Retail credit
on excess generation, 12-month rollover
Residential solar in Maine is compensated through Net Energy Billing at the full retail rate. Credits roll forward for 12 months — size for annual offset, not monthly.
State · Efficiency Maine
$2,000–$6,000
per installation, tier-based
Efficiency Maine offers tiered rebates by efficiency level. Income-qualified households can stack additional rebates. Combined with CMP utility programs, a whole-home install can land $5k+ in rebates.
Utility · CMP & Versant pilots
Pilot rates
vary by utility
Maine's battery dispatch programs are newer and smaller than MA, but operational. Worth enrolling if you're installing storage anyway — the math is incremental upside, not a deal-maker on its own.
How they stack
Several rebates require the work to be done in a specific order, or by a specific kind of contractor. Mass Save heat pump rebates require an audit first. Some battery dispatch enrollments must happen at the time of installation. SMART solar requires the application before construction starts.
We sort all of this out during the consult — not by quoting a generic "up to $X" figure, but by checking exactly what your house, utility territory, and income tier qualify for, and in what order.
