The Minnesota Star Tribune has covered the long-duration battery pilot at the University of Minnesota Morris, which broke ground on October 26 with Otter Tail Power, battery maker Eos Energy Enterprises and OATI.
Reporter Kristoffer Tigue, who attended the groundbreaking, names OATI as the project’s microgrid manager and explains why the zinc design matters for Minnesota: zinc is one of the world’s most widely available metals, the components are sourced in the United States, and the chemistry holds up in the state’s cold. Once the 1-megawatt, 6-megawatt-hour battery is installed in 2027, Otter Tail Power will operate it, the university will study its performance, and OATI GridMind® will manage when it charges and discharges.
…a battery big enough to power its campus for almost an entire work day.

Microgrids for campuses and public buildings
Schools, universities and public agencies are putting storage to work the way UMN Morris is: power that stays on through outages, and energy budgets that earn their keep between them.
