Utility-Scale and Large Commercial Installations

For utility-scale and large commercial installations, take the following additional precautions:

• Access preplan data while responding (Preplanning is essential for effective BESS incident response.)
• Initiate contact with the BESS owner (whether the local property owner or a third-party technology vendor) through your dispatch center.
• Request that a qualified facility subject-matter expert (SME) meet the incident commander on-site. The SME should understand system configuration and battery chemistry under adverse conditions.
• Review, interpret and verify all data sources with the on-site SME to form an operational picture for data-driven incident management.
• Confirm that ventilation is occurring. Only activate an exhaust ventilation system if you can do so remotely.
• Verify automated electrical charge/discharge system disconnect if you can do so remotely.
• Maintain a standoff distance of 100 feet for any Duke Energy BESS facility unless instructed otherwise by a qualified on-site facility SME.
• Do NOT proceed beyond the fence line of any facility or structure without guidance from Duke Energy.
