Home Battery Rebates by State 2026: SGIP, ConnectedSolutions & More
State battery rebates in 2026: California SGIP, Massachusetts ConnectedSolutions, plus programs in Oregon, Maryland, Vermont and VPP payouts — how much, who qualifies, and how to stack with solar.
The 2026 incentive reality
The federal residential credit (25D) expired Dec 31 2025, so state and utility programs are now the main way to cut battery cost. California SGIP, Massachusetts ConnectedSolutions, and programs in Oregon, Maryland, Vermont and others continue to offer roughly $2,000–7,000+ per battery depending on program and income level (solarenergysimplified/getwattwise 2026).
Key programs to check
California: SGIP (Self-Generation Incentive Program) — highest for low-income households; stackable with NEM 3.0 economics. Massachusetts: ConnectedSolutions — paid per kW dispatched during peak events. Vermont/Oregon/Maryland: state battery incentives in various forms. Virtual Power Plant (VPP) programs let utilities pay you (bill credits or cash) for discharging during grid peaks — a growing 2026 income stream that can shorten battery payback.
How to stack and claim
State rebates generally stack with each other and with solar incentives, but not with the expired federal credit. Apply before installation (many programs reserve funds first-come). Income-qualified tiers (SGIP equity budget) can cover 80–100% of cost. Confirm current program terms on DSIRE and your utility — caps and budgets change quarterly.
FAQ
Is there a battery tax credit in 2026?
Not for homeowner-purchased batteries — Section 25D expired Dec 31 2025. Lease/PPA batteries can access the commercial 48E credit, passed through by the lessor.
What is the SGIP battery rebate in 2026?
California's Self-Generation Incentive Program offers tiered per-kWh rebates (highest for low-income equity budget, up to ~80–100% of cost in the highest tier). Check current SGIP budget status before installing.
How much can a battery VPP pay?
VPP programs (e.g., Massachusetts ConnectedSolutions) pay bill credits or cash for peak-event discharges — commonly hundreds of dollars per year, which shortens payback meaningfully.
