Replacing Diesel in an Alaskan Community: Cordova’s New Battery Energy Storage System

Thursday, May 7, 2020 @ 2:00 PM - 3:30 PM ET

Join us for a DOE/ESTAP webinar with the Cordova Electric Cooperative to learn about its recently installed energy storage system. With the help and support of US DOE Office of Electricity and Sandia National Laboratories, Cordova installed its 1MW/1MWh utility-scale lithium-ion system in June 2019 to allow the utility to harness more hydropower and reduce reliance on diesel fuel.

This webinar explained how evaluation, analysis, and modeling led to the installation of the battery. In addition, Cordova Electric explained the battery’s main functions on its hydropower microgrid and detailed the battery’s performance during a 2-day operation last November, in which the coop was able to avoid spilling hydro generation capacity. Lastly, the panelists covered battery operation and project financing.

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 U.S. ESTAP is funded by the U.S. Department of Energy Office of Electricity, managed by Sandia National Laboratories, and administered by the Clean Energy States Alliance.
