Standard requirements for tiered solar container batteries

This guide includes visual mapping of how these codes and standards interrelate, highlights major updates in the 2026 edition of NFPA 855, and identifies where overlapping compliance obligations may arise. Provisions appropriate to the battery technology shall be made for sufficient diffusion and ventilation of gases from the battery, if present, to prevent the accumulation of an explosive mixture. The 2022 Building Energy Efficiency Standards (Energy Code) has battery storage system requirements for newly constructed nonresidential buildings that require a solar photovoltaic (solar PV) system (2022 Nonresidential Solar PV Fact Sheet). 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 sources including:.
