Home Battery Storage Rebates 2026: What's Still Available
The Federal Tax Credit Is Gone
The 25D residential energy credit covered 30% of home battery storage costs as of 2024 and early 2025. The One Big Beautiful Bill eliminated it effective December 31, 2025. A 10 kWh battery system costing $10,000–$15,000 installed would have generated a $3,000–$4,500 federal tax credit under 25D. That credit no longer exists.
The result: battery storage economics changed materially at the start of 2026. The decision calculation now depends heavily on state programs, utility rate structures, and local incentives — not a federal baseline that applied everywhere.
What Still Exists: State and Utility Programs
California: SGIP (Self-Generation Incentive Program)
California's SGIP is the largest remaining residential battery storage rebate program in the country. The program pays per kWh of battery capacity installed:
| SGIP Tier | Eligibility | Rebate per kWh | 10 kWh Example |
|---|---|---|---|
| Standard | Any California customer | $200/kWh | $2,000 |
| Equity | Low-income (CARE/FERA/LIHEAP) | $350–$500/kWh | $3,500–$5,000 |
| Equity Resiliency | Low-income + high fire/outage risk | Up to $1,000/kWh | Up to $10,000 |
SGIP availability depends on program blocks — each utility territory has allocated funding that can reach capacity. Check current SGIP availability at sgipinfo.com before planning a battery installation that depends on this incentive. Equity Resiliency tier in high-fire-risk areas has at times had multi-year waitlists.
For California homeowners, SGIP remains a meaningful incentive despite the 25D expiration. The Equity Resiliency tier in particular can fund the majority of battery storage costs for qualifying households in areas with high wildfire risk and frequent outages.
Oregon: Solar + Storage Program
Oregon's Department of Energy has administered solar + storage rebate programs, though funding has been periodic rather than continuous. Check with ODOE at oregon.gov/energy for current program availability and funding. When available, Oregon's storage rebates have ranged from $1,000–$2,500 per system.
Arizona: APS and SRP Programs
Arizona Public Service (APS) has offered battery storage incentives as part of their time-of-use rate compatibility programs. The incentive structure ties storage to rate plan optimization — customers on APS's time-of-use rates can receive credits for battery systems that demonstrate demand reduction during peak hours. SRP (Salt River Project) in the Phoenix area has run similar programs. Check current availability at aps.com and srpnet.com.
Maryland: EmPOWER Maryland
Maryland's EmPOWER Maryland program, administered through utilities including BGE, Pepco, Delmarva Power, and Potomac Edison, includes storage as part of broader electrification programs. BGE in particular has offered pilot programs for battery storage in its service territory. Contact your Maryland utility for current program status.
Massachusetts: ConnectedSolutions
National Grid and Eversource in Massachusetts offer ConnectedSolutions — a demand response program for battery storage systems. Customers with eligible batteries receive annual bill credits for allowing the utility to dispatch their battery during peak demand events. Credits have ranged from $225–$900 per year depending on battery capacity and participation. This isn't a purchase rebate but a recurring revenue stream that improves storage economics over time.
Utility Rate Arbitrage: The Real Driver Post-25D
In many states where rebate programs are limited, the financial case for battery storage depends on utility rate structure rather than rebates. Two scenarios where storage pencils out without significant rebates:
Time-of-Use Rate Arbitrage
Utilities with time-of-use (TOU) rates charge more during peak hours (typically 4–9 PM) and less during off-peak hours (overnight). A battery charged on cheap overnight electricity and discharged during peak hours captures the rate differential. With peak/off-peak differentials of $0.10–$0.20/kWh (increasingly common in California, Hawaii, New York), a 10 kWh battery cycled daily captures $365–$730 per year in rate savings.
At $0.15/kWh differential with 300 annual cycles, 10 kWh storage provides $450/year in savings. At typical all-in battery storage costs of $10,000–$14,000 without 25D, that's a 22–31 year simple payback — marginal without a significant upfront rebate or incentive.
Backup Power Value
The other battery value driver is backup power during outages. For households that rely on medical equipment, home offices, or simply live in high-outage areas (wildfire-prone regions, hurricane-prone coastal areas), the value of backup power may justify battery costs independently of utility savings. This is qualitative value — it doesn't produce a clean financial return but is real to households that have experienced extended outages.
Leading Battery Systems: What's Being Installed
| System | Capacity | Typical Installed Cost | Notes |
|---|---|---|---|
| Tesla Powerwall 3 | 13.5 kWh | $11,000–$15,000 | Integrated solar inverter, high market share |
| Enphase IQ Battery 5P | 5 kWh (scalable) | $6,000–$8,000/unit | Modular, AC-coupled, installer network |
| SolarEdge Home Battery | 9.7 kWh | $9,000–$12,000 | Integrates with SolarEdge inverters |
| LG RESU Prime | 9.6 kWh | $8,500–$11,000 | Competitive mid-tier option |
| Generac PWRcell | 9–18 kWh (modular) | $10,000–$20,000 | Whole-home backup option |
Installed costs vary significantly by installer and region. Get quotes from multiple installers — battery storage pricing is competitive enough that quotes can vary by 20–30%.
Solar + Storage: The Strongest Case
Pairing battery storage with solar maximizes value in most markets. Solar charges the battery during the day; the battery powers the home during peak evening rates or outages. This combination:
- Maximizes solar self-consumption (using solar-generated electricity rather than selling it back at low export rates)
- Captures TOU rate differentials
- Provides backup power capability
California's NEM 3.0 net metering structure specifically incentivizes storage pairing — the low export rates under NEM 3.0 make storing solar and using it later more valuable than exporting. For California solar buyers post-25D, battery pairing becomes more compelling under NEM 3.0 than it was under NEM 2.0.
See the solar rebates still available guide alongside this article for the complete solar + storage picture in 2026. The California rebate page has current SGIP availability and amounts.
HEAR and Battery Storage
HEAR does not cover battery storage — the program covers heat pumps, water heaters, panel upgrades, insulation, wiring, stoves, and dryers. If battery storage requires an electrical panel upgrade (common for whole-home battery systems), that panel upgrade may qualify for HEAR's $4,000 maximum rebate independently, even if the battery itself doesn't qualify.
For states that have combined battery storage into their HOMES-adjacent programs, check with your state energy office. A few states have bundled storage incentives with whole-home energy programs. See the guide to stacking rebates for how to coordinate multiple programs on the same project.
Hawaii: The Exception That Proves the Rule
Hawaii deserves separate mention in the post-25D battery storage landscape. Hawaii's electricity rates — averaging $0.35–$0.40+/kWh — make the TOU rate arbitrage math dramatically different from the mainland. With retail rates that high, a 10 kWh battery capturing a $0.15 peak/off-peak differential provides $547/year in savings versus $273/year at $0.15/kWh mainland rates. The payback period in Hawaii, even without SGIP, can run 15–18 years on a $12,000 system — still challenging, but closer to viable.
Hawaii also has its own battery storage incentive programs through the Hawaii State Energy Office and Hawaiian Electric's demand response programs. The combination of high electricity rates, island grid stability concerns (incentivizing storage for grid services), and state programs makes Hawaii the strongest mainland-comparable market for battery storage outside California.
What to Watch: Utility Virtual Power Plant (VPP) Programs
The most promising development in battery storage economics post-25D is Virtual Power Plant programs — utilities aggregating home batteries to provide grid services and paying homeowners for participation. Sonnen and Tesla have VPP programs in some markets, and utilities including Green Mountain Power (Vermont), Pacific Power (Oregon), and others have piloted residential battery aggregation programs.
VPP payments can run $500–$1,500/year for participating systems in high-value markets. These are not rebates but recurring revenue streams that dramatically change the battery economics over a 10-year period. If you're evaluating battery storage in 2026, research available VPP programs in your area alongside utility rebates — the combination of VPP revenue and state rebates may provide the business case that purchase rebates alone no longer do in most markets.
Check with your utility, with Tesla Energy's customer service for Powerwall VPP availability, and with Sonnen at sonnen.com for ecoLinx VPP program eligibility in your area. The California rebate page lists SGIP alongside VPP information for California customers.
