6 Frequently Asked Questions about “Requirements for the installation location of energy storage equipment”

What is required working space in and around the energy storage system?

The required working spaces in and around the energy storage system must also comply with 110.26. Working space is measured from the edge of the ESS modules, battery cabinets, racks, or trays.

How do I plan a new energy storage system?

It is important to plan and discuss the location of an energy storage system with the electrical inspection authorities before installation of this equipment. In many cases, this will include the building inspector and the fire marshal.

Are energy storage systems safe?

The emergence of energy storage systems (ESSs), due to production from alternative energies such as wind and solar installations, has driven the need for installation requirements within the National Electrical Code (NEC) for the safe installation of these energy storage systems.

Can pre-engineered and self-contained energy storage systems have working space?

Language found in the last paragraph at 706.10 (C) advises that pre-engineered and self-contained energy storage systems are permitted to have working space between components within the system in accordance with the manufacturer's recommendations and listing of the system.

Why do energy storage systems need security measures?

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.

Are energy storage systems connected to other energy sources?

Energy storage systems can be (and typically are) connected to other energy sources, such as the local utility distribution system. There may be one or more sources connected to an ESS. The connection to other energy sources is required to comply with the requirements of 705.12.
