Advanced Battery Storage, October 23-24, 2019 in Denver, CO

Utilities across the country are rapidly deploying energy storage technologies. Battery energy storage systems (BESS) can be used for a variety of applications, including frequency regulation, demand response, transmission and distribution infrastructure deferral, integration of renewable energy, and microgrids. This storage technology is vital, as it turns power generated by non-dispatchable energy sources — such as wind and solar — into dispatchable ones, thereby improving grid reliability and allowing the integration of even more renewable capacity.

As storage emerges into the utility and power system mainstream, gaps in safety practices for energy storage technologies are coming to light. Concerns regarding large-scale energy storage facilities, especially those using lithium-ion batteries, are driving the requirements for improved knowledge of safety hazards and updating long-established standards to ensure the storage industry’s integrity and future growth.

This course will provide an in-depth overview of the hazards and operating risks associated with battery storage. In addition, it will provide a brief review of the different battery types, new standards that help with safety, how to design and operate for safety, and testing standards.  Finally, it will also address the decommissioning removal and disposal protocols for batteries.

Learning Outcomes

  • Review the different types of battery storage
  • Identify the different types of safety hazards for batteries
  • Review the hazards associated with each type of battery
  • Discuss the testing standards and certifications for safety
  • Discuss how to design for safety and operating safely
  • Examine installation measures for batteries
  • Discuss decommissioning & removal practices
