What does it do?

SB1252 limits municipal regulation of installing or inspecting qualifying residential backup-energy systems, while preserving municipally owned utilities’ authority within their service areas. A covered system is installed at residential property and can provide no more than 50 kilowatts of electricity to the residence or has storage capacity of no more than 100 kilowatt-hours. Kilowatts measure power output; kilowatt-hours measure stored energy. The statute uses “or,” not a requirement to meet both limits. Final law, sections 1–4.

The act bars a municipality from adopting or enforcing a National Electrical Code amendment that regulates these systems’ installation or inspection. It separately bars municipal ordinances, rules or other measures regulating that installation or inspection. Both provisions preserve a municipally owned utility’s authority to regulate the same activities within its service area. That defined term includes a utility owned, operated and controlled by a municipality or by a nonprofit corporation whose directors are appointed by one or more municipalities. Final law, sections 2 and 4; Utility definition.

The bill became law without the governor’s signature on June 20, 2025. It took effect September 1, 2025, and applies only to installation or inspection initiated on or after that date. The act does not promise that an existing installation qualifies or that a utility must connect a particular system. Official history; Final law, sections 5–6.

What changed along the way?

The Senate committee substitute added the municipally owned utility exception to both restrictions; the introduced bill did not contain it. Those exceptions survived unchanged through the Senate-passed, House committee and enrolled texts. The official amendment index lists no floor amendments. This was a committee-substitute change, not a floor amendment. Introduced bill; Senate substitute; All versions; Amendment index; Final law.

The prior municipal electrical-code statute allowed local amendments and administration/enforcement procedures. SB1252 adds the specific restriction without deleting the underlying statutory adoption of the National Electrical Code. It also expands the solar-energy subchapter’s heading to cover backup-energy devices and adds a separate backup-system section; it does not rewrite the existing solar-device section. It should not be described as abolishing all electrical standards or all utility oversight. Prior electrical-code statute; Existing solar-device provision; Final law.

Who could benefit—and who could bear the costs?

Owners and installers of qualifying systems may face fewer municipal installation or inspection requirements, but municipal utilities retain the stated authority in their service areas. Municipal governments lose discretion covered by the new restrictions. The law does not subsidize a generator or battery, guarantee lower installation costs, ensure outage protection, or decide whether a particular property and system satisfy every applicable requirement. Final law.

The March 10 introduced and March 18 substitute fiscal notes anticipate no significant state or local-government fiscal impact, assuming state costs can be absorbed using existing resources. Neither quantifies homeowner savings or the effect on any city’s inspection revenue or workload. The act makes no appropriation. Introduced fiscal note; Substitute fiscal note.
