Home Battery Tax Credit Ended: Colorado Still Has Battery Backup Rebates

The 30% federal home battery tax credit disappeared on December 31, 2025. No phase-down, no partial credit, no extension.

If you’re a Colorado homeowner researching battery storage in 2026, you’ve likely run into articles that still describe the 30% residential clean energy credit as fully active. Most of those pieces were written before the One Big Beautiful Bill became law on July 4, 2025. That legislation ended the home battery tax credit for any system placed in service after December 31, 2025, cutting the original credit timeline short by seven years.

That represents a significant change in the financial equation. For a typical $13,500 battery install, the federal credit previously provided a $4,050 reduction in direct tax liability. That benefit is no longer available for 2026 installations.

Colorado’s state and utility battery rebates didn’t disappear, though, and the Colorado rebate stack becomes the primary financial incentive available to homeowners.

When stacked correctly, the financial incentives available to a Denver homeowner on Xcel’s grid may reduce installation costs by up to 40%, depending on eligibility and program availability. The payback period is longer without the federal credit, but the economics may still work for some homeowners depending on their specific situation and available incentives.

What the One Big Beautiful Bill Did to the 25D Credit

Section 25D, the residential clean energy credit, provided homeowners with a 30% federal tax credit for eligible battery storage systems, solar panels, geothermal heat pumps, and other clean energy property. This credit also applied to solar installations when paired with battery storage. Before the OBBB, the Inflation Reduction Act had extended that credit through 2032 with a gradual phase-down starting in 2033.

The One Big Beautiful Bill (Public Law 119-21), signed July 4, 2025, ended Section 25D for residential homeowners seven years ahead of schedule. Under the new law, any clean energy property placed in service after December 31, 2025, no longer qualifies for the residential credit. The deadline is firm with no exceptions. There is no partial credit for systems ordered before 2026 but installed after. “Placed in service” means operational and installed, not ordered or contracted.

This matters for battery storage specifically because standalone battery systems became eligible for the residential credit under the IRA in 2023, meaning they no longer needed to be paired with solar panels to qualify. That expansion, combined with the 30% rate, made batteries substantially more affordable for homeowners who bought them between 2023 and 2025.

The commercial equivalent, Section 48E (the Clean Electricity Investment Credit), was not eliminated by the OBBB and continues through 2032. That distinction matters for leased systems, covered in detail below.

For any battery storage system placed in service on or after January 1, 2026, the federal government offers no residential battery tax credit. Homeowners who were tracking the Xcel Energy battery rebate programs as a supplement to the federal credit now need to model incentives without that 30% baseline.

Colorado State and Utility Rebates Still Available

Colorado’s financial incentives for battery storage did not change with the OBBB. The federal government’s decision to end Section 25D didn’t affect state programs, utility programs, or municipal rebates. For a homeowner on Xcel’s grid in Denver, Golden, or elsewhere on the Front Range, the incentive stack may still be substantial.Xcel Energy Programs

Xcel runs two separate battery incentive programs that serve different purposes.

1. The Xcel PSPS Battery Rebate offers up to $10,000 (subject to program availability and funding) for customers in Tier 2 or Tier 3 wildfire risk zones who have a qualifying medical need for reliable power. Funding comes from a dedicated annual budget on a first-come, first-served basis. Income-qualified customers in the highest-risk tiers may have up to 100% of their installation costs covered.
2. The Renewable Battery Connect program is Xcel’s virtual power plant and is open to more homeowners. Participants receive an estimated $350 per kilowatt of continuous discharge capacity at enrollment (as of early 2026, subject to program terms). For a standard home battery storage system with 11.5 kW output, the total is roughly $4,025 upfront.

Eligibility requirements are specific. Not every Denver homeowner qualifies, but foothill communities and wildfire-adjacent areas frequently do for the PSPS Battery Rebate. REenergizeCO’s team checks each customer’s address against the Xcel wildfire risk tier map during every battery consultation.

City of Golden

Golden homeowners can access up to $3,000 through the Battery Backup Rebate, which is confirmed as active in 2026 on the City of Golden rebates page. The rebate requires pairing with a new or existing rooftop solar system at the same address. Standalone battery installations without solar do not qualify. Beyond the city rebate, Golden homeowners can stack the Xcel Renewable Battery Connect payment, a 10% Colorado state residential energy storage tax credit (claimed on Form DR 1307), and Xcel net metering benefits.

Colorado’s incentive ecosystem didn’t shrink when the federal credit ended. The state and local incentives that were available before OBBB remain in place. Combining different programs together remains a reliable path to making battery storage technology more affordable for Front Range homeowners.

Battery Payback Math With and Without the Federal Credit

The federal credit shaved years off a typical Colorado battery payback period. Here is an honest side-by-side comparison using a 13.5 kWh battery installed in Denver, with conservative assumptions throughout.

Three Ways to Make a Battery Pay Off in 2026

The homeowners who will recover their investment on a 2026 battery share three approaches. None requires the federal credit. All are available to Colorado homeowners today.

Here are the three plays that move the numbers:

1. Enroll in Xcel’s virtual power plant program. The Renewable Battery Connect program pays over $4,000 at enrollment for a standard-sized system plus an estimated $500 in annual credits over five years (subject to program terms). Enrollment is handled by your installer at the time of installation, not after. REenergizeCO is a certified Tesla Powerwall installer and manages the Xcel VPP enrollment process for every battery storage project on the Front Range.
2. Pair the battery with solar panels. A standalone battery storage system relies on grid electricity during off-peak hours, capturing only the rate differential. Solar plus battery replaces grid purchases during the day and stores the excess for evening peak discharge. This combination may yield an estimated $400 to $600 in annual savings compared to battery-only systems, and it may qualify for additional utility incentives designed specifically for solar-plus-storage configurations.
3. Configure time-of-use settings from day one. Xcel’s TOU rate plans create a meaningful price spread between off-peak and on-peak hours. Programming your battery to charge overnight and discharge during the afternoon peak window automates utility savings without any ongoing effort. Over 10 years or more, consistently avoiding peak-rate consumption may reduce your effective net system cost in compounding ways.

What Comes Next

Installing a home battery in 2026 without the federal credit takes more precision than it did last year. The math is harder, not impossible. Colorado’s state and local incentive stack, combined with Xcel’s virtual power plant payments and time-of-use rate optimization, gives you real tools to build a compelling case.

The federal government is no longer contributing 30% off the top. That’s the new reality for residential battery storage. But Colorado’s programs, Xcel’s rebates, and smart system configuration make the investment worth running the numbers on.

The difference between short- and long-term payback comes down to the details: your rate plan, your city, your solar setup. Schedule a free home energy consultation with REenergizeCO, and we will run the numbers for your home using the incentives still available in 2026.
