Supplying Secure Power with Properly Installed Energy Storage Systems
The growth of Energy Storage Systems (ESS) used to supply secure power to larger systems created the need to develop more standards around performance and safe installation. These standards are especially true when ESS are installed in residential, commercial, and industrial installations. These areas are now seeing much larger battery systems and newer Lithium Ion technology. The standards that will be reviewed during this presentation will be focused on NFPA 70 (National Electric Code) Articles 705 (Interconnected Electric Power Production); 706 (Energy Storage Systems); and 710 (Stand Alone Systems). These code articles provide the statutory requirements based on what version of the NEC that an individual state has adopted. A brief overview of the current state of NEC adoption will be included. There are additional standards IEEE 1375, Guide for the Protection of Stationary Battery Systems, and others in development like National Fire Protection Association (NFPA) 855 Standard for the Installation of Stationary Energy Storage Systems. These will be addressed briefly to give the attendee a view of ESS codes/standards’ future.
