VT · Vermont

Vermont punches way above its weight on utility programs.

Efficiency Vermont covers the state-side stack: heat pump rebates, weatherization, income-qualified bonuses. On top of that, three utilities each layer their own programs. Green Mountain Power runs the most aggressive battery program in the country, Vermont Electric Cooperative is the rural co-op that mirrors GMP's net metering closely, and Burlington Electric is the only municipal in the state, with its own heat pump rebate that beats the EVT stack on big systems. Here's exactly what each one offers, in 2026.

The richest battery program in the country

GMP's Bring Your Own Device program pays up to $950/kW, with a $100/kW grid-need bonus and a $10,500 cap.

Customer-owned batteries enrolled at 4-hour discharge duration earn $950/kW upfront ($850/kW at 3-hour duration), plus a $100/kW bonus in high-need grid areas, up to a $10,500 total rebate. GMP runs an average of 5 to 8 dispatch events per month at 3 to 6 hours each, so participation is real, not nominal. Tesla Powerwall, Enphase IQ Battery, and FranklinWH all qualify; the Vermont PUC lifted enrollment caps in 2024 and there is no waitlist. Nothing in MA, NY, MD, or CT comes close on $/kW or on dispatch frequency.

Green Mountain Power (GMP)

GMP is the largest electric utility in Vermont, serving roughly 75% of Vermont homes across most of the state's central, southern, and Champlain Valley territory. It is also one of the most progressive investor-owned utilities in the country: the Powerwall lease and BYOD programs together set the national bar for utility-side battery economics.

Vermont Net Metering, Category I (≤15 kW residential)
~$0.18116/kWh blended + adders
Blended residential base rate around $0.18116/kWh, plus a $0.01/kWh REC adjuster (10 years from commissioning, systems under 15 kW), plus an additional $0.03/kWh if the customer transfers RECs to GMP, for a stacked $0.04/kWh bonus on top of the net-metering rate. Note: the VT PUC has trimmed the residential adjustor 7 years running; the bonus could turn negative in future PY filings.

GMP Powerwall Lease
Flat monthly fee · GMP dispatch

Insulation & weatherization · via Efficiency Vermont
Efficiency Vermont Home Performance
Income-tiered coverage
GMP routes weatherization through Efficiency Vermont. Strong income-tiered coverage on insulation and air sealing; income-qualified households often see no-cost or near-no-cost work. EVT Home Performance is a prerequisite for the income-eligible heat pump bonus stack.

No utility rebate available
GMP does not offer a windows/doors rebate. The federal 25C credit (up to $600/year for windows) expired Dec 31, 2025 with no utility replacement program. Inherent ROI (utility savings, comfort, resale value) is the case for the upgrade.

Vermont Electric Cooperative (VEC)

VEC is a member-owned rural electric co-op serving roughly 32,000 members across northern Vermont, including the Northeast Kingdom and the Islands. The program lineup mirrors GMP's net-metering structure closely but,, VEC has historically deferred to Efficiency Vermont and federal pathways for storage rather than running its own battery program.

VEC members receive Efficiency Vermont's statewide heat pump rebates on the standard EVT schedule. No VEC-specific heat pump bonus has been identified; income-eligible bonuses route through EVT directly.

VEC Net MeteringWatch the siting charge
$0.18116/kWh · $0.04/kWh siting
VEC pays the blended residential rate, currently $0.18116/kWh, on excess production. For systems ≤150 kW filed on or after Aug 1, 2024, a $0.04/kWh siting charge applies on every kWh produced (offset against credits). Systems greater than 150 kW carry a $0.07/kWh siting charge. The siting charge meaningfully reduces the effective NM credit on new VEC interconnections; always model net-of-siting in your payback math.

Burlington Electric Department (BED)

BED is the only municipal electric utility in Vermont, serving the City of Burlington (around 10% of state load). It runs its own rebate stack independent of Efficiency Vermont; BED customers are excluded from EVT income bonuses but the BED heat pump rebate runs richer per-ton on larger systems, and the air-to-water rebate is the most generous in the state.
