Earlier this month, Minnesota-based Xcel Energy announced it wants to double the amount of lithium battery storage it already planned to install next to its Sherco coal-fired power plant in central Minnesota. The batteries would allow Xcel to store energy produced at its wind, solar, nuclear and natural gas plants across the Upper Midwest.

MPR News reporter Kirsti Marohn has been covering how batteries that store electricity on demand are becoming an increasingly important part of the transition to clean energy. She joined MPR News host Nina Moini to share more about her reporting as part of a weekly check in with MPR News reporters based in greater Minnesota.
