Battery Energy Storage Systems represent the future of grid stability and energy efficiency. However, their successful implementation depends on the careful planning of key site requirements, such as regulatory compliance, fire safety, environmental impact, and system integration.
A public benefit corporation, NYSERDA has been advancing energy solutions and working to protect the environment since 1975. The Battery Energy Storage System Guidebook contains information, tools, and step-by-step instructions to support local governments managing battery energy storage system development in their communities.
Battery energy storage systems (BESS) stabilize the electrical grid, ensuring a steady flow of power to homes and businesses regardless of fluctuations from varied energy sources or other disruptions. However, fires at some BESS installations have caused concern in communities considering BESS as a method to support their grids.
Systems in these locations are also limited to 40 kilowatt-hours (kWh) of storage capacity. In all other locations noted above, the size limit is 80 kWh. On the exterior walls of the home, it’s important to note that systems cannot go within 3 feet of doors or windows leading directly into the home.
The Inspection Checklist is intended to be utilized as a guideline for field inspections of residential and small commercial battery energy storage systems. It can be used directly by local code enforcement officers or provided to a third-party inspection agency, where applicable.
Given the scale of energy storage systems and the value of the equipment involved, security is another top concern for BESS installations. These systems are often located in remote or semi-isolated areas, making them vulnerable to theft, vandalism, or sabotage. Therefore, implementing strong physical security measures is essential.
