SB 1252 Brings New Rules for Residential Energy Backup Systems in Texas

The Texas Legislature has passed Senate Bill 1252, which takes effect September 1, 2025, to update how residential energy backup systems are regulated across the state. Under the law, “residential energy backup system” refers to systems installed at homes that produce no more than 50 kilowatts of electricity or have a storage capacity of no more than 100 kilowatt-hours.

Key Changes Under SB 1252

• Municipalities can no longer adopt amendments to the National Electrical Code (NEC), nor enforce any local ordinance, rule, or measure that adds extra regulation for residential energy backup systems beyond the new state law.
• Municipally-owned utilities (as defined in Utilities Code § 11.003) retain authority in their service areas to regulate the installation and inspection of these backup systems, even under the new law.
• All electrical work connected to residential energy backup systems that is not exempt must still comply with Chapter 1305 of the Texas Occupations Code and the National Electrical Code. Importantly, the installation must be carried out by licensed electrical contractors and electricians in Texas.

What Electricians Need to Know

This change simplifies some regulatory hurdles, but also clarifies where your responsibilities lie:

• If you’re installing or inspecting residential backup systems (inverters, battery cabinets, etc.), you’ll need to ensure your work meets NEC standards, and that you are properly licensed.
• You’ll no longer need to navigate varying local amendments to the NEC related to backup systems (for most municipalities), though utility districts might still impose their own rules. Being familiar with local utility regulations remains critical.
• Starting September 1, lay out clean contracts and project specs that reference state law SB 1252, so clients understand what’s required and what municipalities cannot force on you.

These changes aren’t just legal procedure—they create real opportunities and shape the future landscape for electricians in Texas.

What’s Next: SB 1252 went live September 1. If you work in residential backup energy systems, review your current and upcoming jobs, ensure you understand what your local utilities allow, and gear up your teams for compliance under the new standards.
