What is the recommended initial evacuation distance from battery energy storage systems?

The recommended initial evacuation distance from battery energy storage systems is 150 feet. This distance is established to enhance safety in the event of a battery failure, fire, or other hazardous situation that may arise from the storage of energy. A larger safety perimeter allows for a reduction in risk to personnel and the public, as certain factors can cause battery systems to release toxic gases, explode, or create other dangerous conditions.

Having an evacuation distance of 150 feet is based on industry standards that take into account the potential hazards associated with various types of battery technologies, including their chemistry and the size of the storage system. This distance is deemed effective in providing time and space for emergency services to respond while protecting individuals from potential harm.

In contrast, shorter distances may not provide adequate safety margins, especially in the event of more severe incidents. By recommending 150 feet, it reflects a cautious and proactive approach to safety management in relation to energy storage systems.
