FDNY Fire Code 

The FDNY released its first-ever list of energy storage equipment that has received the FDNY’s Certificate of Approval (COA) – a rigorous assessment of a product’s design, construction, and safety performance.  The COA establishes installation criteria for the product allowing a reduced approval timeline from FDNY.  This list can be accessed via the FDNY Business website’s Certificate of Approval webpage. For guidance on submitting an FDNY COA application for ESS products see the COA Getting Started Guide.
