State Battery Storage Incentives in 2026: SGIP and the Other Programs Worth Knowing

Home battery storage lost its federal tax credit on the same date solar did — the Section 25D repeal covered both owned solar systems and owned battery storage, standalone or paired, for installations completed after December 31, 2025. That's a meaningful loss, since batteries are expensive ($9,000–$20,000 installed for a typical home system) and previously qualified for the same 30% credit as solar panels.

A small number of states have their own storage-specific programs that fill part of that gap. They're not evenly distributed — if you live outside these states, your battery economics now rest almost entirely on your electric rate structure and backup-power value rather than any direct incentive.

The programs that currently matter most

| State | Program | Structure | Typical value | |---|---|---|---| | California | Self-Generation Incentive Program (SGIP) | Upfront per-kWh rebate, declining in steps as funds are claimed | General market: roughly $150–$250/kWh. Equity Resiliency tier (qualifying low-income or high fire-risk households): roughly $850–$1,100/kWh | | Connecticut | Energy Storage Solutions | Enrollment incentive plus ongoing performance payments for grid exports during peak demand | Up to $16,000 per installation combined; program structure was updated in 2026 | | Massachusetts | SMART storage adder + ConnectedSolutions | Adder on top of the SMART solar production incentive, plus a separate seasonal demand-response payment | ConnectedSolutions: roughly $225–$900/year depending on battery size, recurring | | New York | NYSERDA storage incentive | Upfront per-kWh incentive, plus separate utility programs in some territories | Roughly $200/kWh, up to 25 kWh | | Hawaii | Battery Bonus (Hawaiian Electric) | Tiered upfront payment per kW, plus a monthly bill credit for grid access | Declining tiers, roughly $500–$850/kW depending on enrollment timing | | Maryland | Energy Storage Income Tax Credit | State income tax credit, applied at filing | 30% of installed cost, capped at $5,000 | | Vermont | Green Mountain Power battery program | Utility rebate for demand-response participation | Up to $10,500 | | Colorado | State tax credit + utility rebates | Varies by utility territory | Roughly 10% state credit, plus local utility rebates |

Program budgets, rates, and eligibility criteria for all of these change frequently — several are structured as declining-block programs that explicitly get less generous as more households sign up, and some have had waitlists for their most generous tiers. Confirm current status directly with the program administrator before budgeting around a specific number.

Two very different kinds of incentive, and why the distinction matters

Battery programs generally fall into one of two structures, and conflating them leads to unrealistic expectations:

| | Upfront rebate | Performance-based payment | |---|---|---| | When you receive it | At or shortly after installation | Ongoing, typically annually, over several years | | Example programs | SGIP general market, NYSERDA, Hawaii Battery Bonus | ConnectedSolutions, Connecticut's performance component | | What it requires of you | Usually just owning and registering the system | Letting the utility dispatch your battery during specified peak events | | Best fit for | Homeowners who want the cost reduced immediately | Homeowners comfortable with the utility occasionally using stored capacity |

A program advertised as "up to $16,000" (like Connecticut's) is often a combination of both types — some money upfront, more accumulated over a decade of participation — so it's worth asking your installer to break the total into its upfront and ongoing components before comparing it to a single lump-sum rebate elsewhere.

A worked example: California, three scenarios

Assume a 13.5 kWh battery system costing roughly $16,000 installed.

| Scenario | Rebate rate | Estimated rebate | Net cost | |---|---|---|---| | General market SGIP | ~$200/kWh | ~$2,700 | ~$13,300 | | Equity Resiliency tier (qualifying household) | ~$1,000/kWh | ~$13,500 | ~$2,500 | | Outside California, no state storage program | $0 | $0 | ~$16,000 |

That range — from roughly $2,500 to $16,000 net cost for functionally the same battery — illustrates why "battery storage costs about $X" is a much less useful statement in 2026 than it used to be. Where you live, and whether you qualify for an equity or resiliency tier, now matters more than almost any other variable.

What to check before assuming you qualify

• Income and location criteria: Equity and resiliency tiers (like California's) typically require both an income threshold and, in some cases, residence in a high fire-risk or frequent-outage area.
• Utility territory, not just state: Several programs are administered per-utility, not statewide — Connecticut's program applies to Eversource and United Illuminating customers specifically, for example.
• Program funding status: Rebate-style programs can close mid-year when a funding block is exhausted, reopening later at a lower rate or not at all until the next budget cycle.
• Equipment eligibility: Some programs require batteries from an approved equipment list, or minimum/maximum capacity limits.

FAQ

Is there any federal incentive left for battery storage in 2026? Not for homeowner-owned systems. The federal 25D credit that covered storage expired December 31, 2025, alongside the solar credit. Third-party owned systems (leases) may still access a commercial credit through the leasing company.

Can I stack a state battery rebate with a state solar tax credit? Generally yes, if they're structured as separate programs — a state solar income tax credit and a utility-administered storage rebate are typically independent of each other. Confirm with your installer or state energy office, since interactions vary by program.

Do virtual power plant (VPP) payments count as a state incentive? Not exactly — VPP programs are usually run by the utility or a battery manufacturer's software platform (like Tesla's or Sonnen's), separate from state-administered rebate programs, though some states' performance-based programs function similarly. Either way, they're a recurring payment for letting your battery discharge during grid events, not an upfront discount.

If my state has no dedicated storage program, is a battery still worth it? It depends heavily on your electric rate structure (especially time-of-use rates) and how much you value backup power during outages, since the financial case without an incentive rests entirely on those two factors.
