FIRE PROTECTION EMERGENCY RESPONSE PLAN Lithium Ion BESS

Page | 004

1. Introduction
1.1 Purpose
This Emergency Response Plan (ERP) is provided for the Greenwater Battery Energy Storage System (ESS) project located in Sumner, Washington. The following emergency response procedures are provided so that all fire service personnel understand the practices that are to be followed to prepare for and to provide immediate and effective response to emergencies that may arise at the facility. The ESS conditions will be remotely monitored by BrightNight and service technicians will be on site periodically to maintain the enclosures.
1.2 Limitations
This plan does not imply, nor should readers infer, that its implementation will guarantee that a perfect response will be practical or possible. No plan can shield individuals from all events.
Responders will attempt to coordinate the plan and response according to all applicable laws and standards.
Response to emergencies, events or disasters shall only be undertaken to the level of the responders’ training, Personal Protective Equipment (PPE), and resources available. There may be little to no warning during specific events to implement operational procedures.
The success or failure of all emergency plans depends upon effective training, continual (e.g., annual) review of this response plan, and execution of the response.
Sites and operators shall comply with applicable codes, standards, and other requirements as apply in their locality, even if those codes, standards, and requirements contradict this plan.
Successful implementation of this plan depends on timely identification of capabilities, available resources at the time of the incident and a thorough information exchange between responding organizations and the facility or transporter.
1.3 Facility Description
The Greenwater ESS project is located in Sumner, WA and located on approximately 8 acres of industrial zoned land.
The site utilizes 240 Tesla Megapack 2XL battery enclosures, 60 medium voltage transformers, medium voltage switchgear, project substation with a main power transformer, control room and an O&M building. Access roads will run along the boundary of the site and within the site for maintenance work and first responder access.
Each Megapack 2XL enclosure is comprised of lithium-ion battery modules, power conversion systems, thermal systems, fire detection and protection systems, controls and communication equipment.
