What are the fire and building codes for energy storage systems?
However, many designers and installers, especially those new to energy storage systems, are unfamiliar with the fire and building codes pertaining to battery installations. Another code-making body is the National Fire Protection Association (NFPA). Some states adopt the NFPA 1 Fire Code rather than the IFC.
Should energy storage systems be protected by NFPA 13?
According to the Fire Protection Research Foundation of the US National Fire Department in June 2019, the first energy storage system nozzle research based on UL-based tests was released. Currently, the energy storage system needs to be protected by the NFPA 13 sprinkler system as required.
What are fire codes & standards?
Fire codes and standards inform energy storage system design and installation and serve as a backstop to protect homes, families, commercial facilities, and personnel, including our solar-plus-storage businesses. It is crucial to understand which codes and standards apply to any given project, as well as why they were put in place to begin with.
What is the NFPA 855 standard for stationary energy storage systems?
Setting up minimum separation from walls, openings, and other structural elements. The National Fire Protection Association NFPA 855 Standard for the Installation of Stationary Energy Storage Systems provides the minimum requirements for mitigating hazards associated with ESS of diferent battery types.
Why are building and fire codes important?
Before diving into the specifics of energy storage system (ESS) fire codes, it is crucial to understand why building and fire codes are so relevant to the success of our industry. The solar industry is experiencing a steady and significant increase in interest in energy storage systems and their deployment.
What are NFPA 855 requirements?
The requirements of NFPA 855 also vary depending on where the energy storage system is located. NFPA 855 divides the location of energy storage systems into indoor and outdoor categories. The standard further classifies indoor devices into buildings dedicated to energy storage or in facility spaces for other uses.
