Model Ordinance: Utility-Scale Battery Energy Storage Systems

Guidance for governments developing rules related to utility-scale battery energy storage systems development.

This document is intended to provide guidance to local governments considering developing an ordinance or rules related to the development of utility-scale battery energy storage systems. The recommendations and considerations included in this framework draw from a variety of expert sources, guidance established by national energy laboratories, and existing state laws and local regulations.

ACP’s latest Model Ordinance for Battery Energy Storage Systems offers stakeholders a modernized, technically sound framework for siting, safety, and community engagement. Drawing from the latest fire safety standards, interconnection best practices, and real-world permitting experiences across the U.S., this 2026 edition reflects evolving industry consensus around topics like decommissioning, emergency response coordination, and hazard mitigation.

The American Clean Power Association supports the adoption of NFPA 855, the national fire protection safety standard for grid-connected energy storage. This safety standard, developed by firefighters, fire protection professionals, and safety experts, provides comprehensive requirements and guidance on the design, installation, and operation of energy storage facilities for all site and community contexts.
