608.11.6 Replacement components.
FC § 608.11.6
Any replacement storage battery units or other stationary energy storage system components shall be designed for the same storage battery technology and/or chemistry and be compatible with the existing energy storage system installation. In-kind replacement of existing components (consistent with the listing for the storage battery unit or stationary energy storage system) constitutes maintenance and does not require department review and approval. Department review and approval, and, as applicable, Department of Buildings review and approval, is required in the same manner as an application for a new stationary energy storage system installation for replacement of existing components that effect an alteration of the energy storage system, including: 1. replacement of components included in the storage battery unit listing, or that could otherwise affect the results of the full-scale testing of the battery storage unit; 2. replacement components that use different battery technologies or chemistries (including the electrolyte chemistry in a flow system); and 3. replacement components that change the storage/generating capacity or other functionality of the stationary energy storage system.
