Refer to the information in the Tesla Safety Manual, Section 7 for information provided by the ESS enclosure manufacturer for additional information on Emergency Response, provided in Appendix 8.
The ESS enclosures are under the control of a site Emergency Management System (EMS) or Local Plant Controller (LPC), which in turn communicate with an offsite fleet controller, SCADA operations center, or other third-party dispatch and monitoring entity. The ESS enclosure alarms will be forwarded to the remote operations and remote operations, or staff personnel on the site, can shut down the ESS enclosure(s) remotely if determined necessary. Note that a system shutdown will not de-energize the battery bank or guarantee that a fault or thermal runaway event has been stopped. Responders and staff should not approach the ESS enclosure or attempt to open the ESS enclosure until deemed safe to do so by the O&M Manager, Emergency Response Coordinator, and Subject Matter Expert.
On-site personnel witnessing an emergency should not assume that automated alarms have reached the Local Plant Controller or Emergency Management System or that such alarms have been passed on to remote operations. Such personnel are advised to call 911 and contact remote operations directly, in addition to other key stakeholders described herein.
