GMP pioneered utility-owned residential battery programs and operates one of the largest VPPs in the country. Vermont homeowners can choose between a zero-upfront-cost lease or purchasing their own battery with VPP compensation.
Two paths to battery ownership. Both deliver backup power and grid support.
Green Mountain Power offers a unique program: lease 2 Tesla Powerwalls for $55/month. GMP installs, maintains, and owns the batteries. You get backup power; GMP dispatches during peaks. No upfront cost.
Own your battery and enroll in GMP's bring-your-own-battery program. GMP compensates you for allowing dispatch during peak events, similar to ConnectedSolutions in other states.
GMP is widely recognized as the most innovative utility in NuWatt's footprint. They were among the first US utilities to offer residential battery programs and continue to lead in VPP deployment.
Whether you lease or own, your battery provides backup power during Vermont's frequent winter outages while supporting the grid during peak demand. GMP's programs are designed to benefit both you and the grid.
Both options give you backup power. The key difference is ownership, income, and upfront cost.
| Feature | GMP Lease ($55/mo) | Buy Your Own |
|---|---|---|
| Upfront Cost | $0 -- GMP installs and owns | $12,500-$30,000+ depending on system |
| Monthly Cost | $55/month for 2 Powerwalls | $0 (or loan payments if financed) |
| Backup Power | Yes -- 2 Powerwalls (27 kWh) | Yes -- your chosen system size |
| Peak Dispatch Income | Goes to GMP (they own the batteries) | You receive compensation from GMP |
| Maintenance | GMP handles everything | You are responsible (warranty covers defects) |
| Best For | No upfront cost, want backup power | Maximum long-term value and income |
Understanding GMP's VPP economics helps explain why they offer such attractive battery programs.
ISO-NE forecasts high grid demand for the region, driven by summer AC or winter heating loads.
GMP dispatches thousands of enrolled batteries simultaneously, creating a virtual power plant.
GMP avoids purchasing expensive peak electricity from the wholesale market (sometimes $0.50-$1.00+/kWh).
GMP's savings from avoided peak purchases fund the $55/month lease and BYOB compensation programs.
Section 25D expired December 31, 2025. Vermont compensates through GMP's innovative lease ($55/month for 2 Powerwalls) and BYOB VPP programs. Third-party owned batteries may qualify for Section 48 ITC through July 4, 2026.
