Federal ITC (25D Expired)
Federal Tax Credit Update 2026: The Section 25D residential clean energy credit expired December 31, 2025. Homeowners purchasing batteries or solar + battery systems in 2026 receive $0 in federal tax credits. Third-party-owned systems (leases/PPAs) may still access Section 48/48E if the financing company begins construction before July 4, 2026.
Texas Senate Bill 1252 was signed into law in 2023 and took effect September 1, 2023. It creates a uniform statewide permitting standard for residential energy storage systems, ending the patchwork of inconsistent local regulations that made battery installation unnecessarily difficult.
Before SB 1252, Texas had no uniform standard for residential battery permitting. Each of the state's 254 counties and 1,200+ cities could set their own rules. Some cities required special use permits. Others required fire department reviews that added weeks to project timelines. Some placed arbitrary capacity limits. And some rural counties simply had no permitting path for energy storage at all.
This created a frustrating situation for homeowners and installers alike. A battery system that sailed through permitting in Austin might face months of delays in Plano or be effectively banned in smaller jurisdictions.
SB 1252 creates a floor of permitting rights for residential energy storage. Cities and counties cannot go below this floor — they cannot ban batteries or make the permitting process more burdensome than standard electrical work.
The law aligns all local codes with NFPA 855 (the national standard for stationary energy storage installation) and requires permits to be processed within existing building permit timelines.
The result: a homeowner in any Texas jurisdiction can install a UL 9540-listed battery system through the same permitting process as any other electrical upgrade.
SB 1252 passed with broad bipartisan support during the 88th Texas Legislature. It was championed as both a property rights issue (homeowners should be able to install backup power) and a grid resilience measure following Winter Storm Uri in 2021, which left 4.5 million Texas homes without power for days.
Four core provisions form the backbone of the law. Together, they ensure that every Texas homeowner has a clear, consistent path to installing home battery storage.
Cities and counties cannot prohibit or create unreasonable barriers to residential energy storage systems (ESS). Zoning cannot be used to effectively block battery installations.
All permitting jurisdictions must use NFPA 855 (Standard for Installation of Stationary Energy Storage Systems) as the baseline safety standard. No more patchwork local codes.
ESS permits must be processed within the same timeframe as existing building/electrical permits. No more special review boards or multi-month delays for battery projects.
Applies to all UL 9540-listed battery technologies — lithium-ion (NMC), lithium iron phosphate (LFP), and other certified chemistries. No technology discrimination.
Does not override HOA restrictions on battery placement or visibility
Does not mandate utility interconnection processes or timelines
Does not waive NFPA 855 fire safety setback requirements
Does not provide funding, rebates, or tax incentives for battery installations
The contrast between the old patchwork system and the new uniform standard is dramatic. Here is what changed across Texas's permitting landscape.

Had a 10 kWh capacity cap without special review. A Tesla Powerwall 3 at 13.5 kWh required a variance that could take 8-12 weeks. Post-SB 1252: standard electrical permit timeline.
Required a separate fire department inspection for any lithium-ion battery installation, adding 4-6 weeks to the project timeline. Post-SB 1252: NFPA 855 compliance reviewed during standard permit review.
Many smaller counties had no ESS-specific permitting framework. Installers either skipped permits (creating liability) or avoided these markets entirely. Post-SB 1252: clear statewide path.
Streamlined battery permitting is not just a bureaucratic improvement — it unlocks real benefits for Texas homeowners investing in solar + storage.
Larger batteries mean more backup capacity during ERCOT outages. A 13.5 kWh Powerwall can keep essential loads running 12-24 hours. Without SB 1252, cities like Houston could have blocked this capacity level.
ERCOT Battery Backup GuideMost virtual power plant programs require 10+ kWh of storage. SB 1252 ensures that capacity-adequate systems can be installed anywhere in Texas, opening VPP revenue to homeowners statewide.
TX VPP GuideBatteries let you store excess solar production for evening use instead of exporting at low buyback rates. In deregulated ERCOT territory, self-consumption is the strongest battery value proposition.
TOU Battery GuideTexas faces grid stress at both extremes — summer peaks above 110°F drive record demand, and winter freeze events threaten generation capacity. Batteries provide year-round insurance against both.
Oncor's solar + battery rebate is easier to access with streamlined permitting. Previously, permit delays in some Oncor-territory cities caused homeowners to miss rebate application windows.
Oncor Battery Rebate GuideWant to start with one battery and add more later? SB 1252 ensures that stacking multiple units (e.g., 4 Enphase IQ 5P units for 20 kWh) will not trigger different permitting requirements than the original installation.

All four featured systems use lithium iron phosphate (LFP) chemistry. LFP batteries handle Texas heat better than NMC chemistry (rated to 113-122°F), have zero thermal runaway risk, and are preferred by Texas insurers. The non-flammable electrolyte also simplifies NFPA 855 compliance.
SB 1252 solved the biggest permitting barriers, but some restrictions remain. Here is what homeowners still need to navigate.
Texas Property Code 202.010 protects solar panels from HOA bans, but batteries have less statutory protection. HOAs can still restrict exterior visibility and placement of battery units. Indoor or garage installations avoid most HOA issues.
Fire code setbacks still apply regardless of SB 1252. NFPA 855 requires minimum distances from exits, operable windows, ignition sources, and other battery units. Typical setback: 3 feet from doors/windows.
Outdoor battery installations in HOA communities may require visual screening (fencing, landscaping) to conceal equipment. This adds $500-$1,500 to project costs but does not prevent installation.
SB 1252 does not mandate utility interconnection processes. Each utility (Oncor, CenterPoint, AEP Texas, etc.) still has its own DER interconnection application, timeline, and requirements.
If your HOA restricts exterior battery placement, a garage installation solves the problem. Tesla Powerwall 3, Franklin WholePower, and Enphase IQ batteries are all rated for indoor installation. Garage-mounted batteries are invisible from the street and exempt from most HOA architectural review.
SB 1252's standardization of NFPA 855 compliance has simplified the insurance landscape for home battery systems in Texas.
Most major TX insurers now cover home batteries under standard homeowner policies
Some insurers require a battery rider or endorsement — typically $50-$150/year
LFP (lithium iron phosphate) preferred by insurers due to non-flammable electrolyte and higher thermal stability
NFPA 855-compliant installation is typically required for coverage — SB 1252 ensures this statewide
Batteries covered at replacement cost. Notify insurer within 30 days of installation to avoid coverage gaps.
Lithium iron phosphate (LFP) batteries use a non-flammable electrolyte and have no thermal runaway risk under normal failure modes. This is why all major home battery manufacturers have shifted to LFP for residential products and why Texas insurers increasingly prefer LFP over older NMC chemistry.

Everything Texas homeowners ask about SB 1252 and battery permitting.
Senate Bill 1252 is a Texas state law signed in 2023 (effective September 1, 2023) that standardizes permitting for residential energy storage systems (batteries). It prohibits cities and counties from banning or unreasonably restricting home battery installations and aligns safety standards with NFPA 855.
No. Under SB 1252, cities and counties cannot ban or unreasonably restrict residential energy storage systems that are UL 9540-listed. They must process ESS permit applications within the same timeline as standard building/electrical permits. However, they can still enforce NFPA 855 fire safety setbacks.
No. SB 1252 applies to government permitting authorities (cities, counties), not private homeowner associations. While Texas Property Code 202.010 protects solar panels from HOA bans, batteries do not have the same statutory protection. HOAs can still restrict exterior placement and visibility of battery units.
SB 1252 covers all UL 9540-listed technologies, including lithium-ion (NMC), lithium iron phosphate (LFP), and other certified battery chemistries. The key requirement is UL 9540 listing — this is the standard for energy storage system safety.
No. The Section 25D residential clean energy credit expired December 31, 2025. Homeowners who purchase batteries in 2026 receive $0 in federal tax credits. However, third-party-owned systems (leases/PPAs) may still access Section 48/48E if the financing company begins construction before July 4, 2026.
Under SB 1252, ESS permits must be processed within the same timeframe as standard electrical permits — typically 5-10 business days for residential projects. Before SB 1252, some jurisdictions took 6-10 weeks due to special reviews or fire department inspections.
No. SB 1252 only addresses local government permitting. Each utility (Oncor, CenterPoint, AEP Texas, TNMP, etc.) still has its own distributed energy resource (DER) interconnection application process and timeline. Utility interconnection typically takes 2-6 weeks separately from permitting.
NFPA 855 requires minimum setbacks from exits, operable windows, and ignition sources (typically 3 feet). Batteries must have proper ventilation, signage, and be installed on non-combustible surfaces or with fire-rated barriers. These fire safety requirements apply statewide regardless of SB 1252.
SB 1252 primarily targets residential energy storage systems. Commercial and utility-scale installations have separate permitting frameworks and are typically subject to more detailed review processes under NFPA 855 and local fire codes.
Yes. SB 1252 prohibits arbitrary capacity caps for UL 9540-listed systems. You can stack multiple battery units (e.g., 3-4 Enphase IQ 5P units for 15-20 kWh, or add a second Tesla Powerwall 3 for 27 kWh) without hitting the capacity restrictions that previously existed in some jurisdictions.
