Energy Storage in Chattanooga, TN: Creating Community Resiliency and Peak Demand Reduction with EPB

EPB, a municipal electric distribution utility serving approximately 190,000 homes and businesses in Chattanooga, Tennessee, has installed energy storage systems at four locations in its service territory. The energy storage systems have two primary use cases. The first is resiliency for critical community facilities such as the Chattanooga Police Department. The second is peak demand reduction, which saves money for EPB’s customers. EPB’s first energy storage project was started in 2017 and was funded by ARPA-E. More recently, EPB partnered with Sandia National Laboratories and the US Department of Energy, Office of Electricity on an energy storage system that supports a microgrid for EPB’s control center campus. EPB is in the process of implementing three additional energy storage sites in its service territory, nearing a total of over 12 MW of energy storage in service.

This webinar featured presentations by Jim Glass and Aaron Willey from EPB. They reviewed EPB’s operational storage projects, and discussed use cases, business models, and lessons learned. They also discussed EPB’s plans for future storage projects.

This webinar also featured introductory remarks by Dr. Imre Gyuk of the US Department of Energy Office of Electricity. Waylon Clark from Sandia National Laboratories joined the Q&A portion of the webinar. Todd Olinsky-Paul of the Clean Energy States Alliance moderated.

This webinar was a presentation of the Energy Storage Technology Advancement Partnership (ESTAP). ESTAP is a federal-state funding and information sharing project that aims to accelerate the deployment of electrical energy storage technologies in the US. ESTAP is funded by the US Department of Energy Office of Electricity under the direction of Dr. Imre Gyuk; managed by Sandia National Laboratories; and administered by the Clean Energy States Alliance.
