In just four months, Invenergy has completed construction and commenced operation of a 4-MWh battery storage system in Knoxville, Iowa for MidAmerican Energy. The energy company is based in Des Moines, Iowa but its service area includes portions of Iowa, Illinois, South Dakota, and Nebraska. In 2016, MidAmerican announced plans to provide 100 percent renewable energy to its customers. Thanks to energy storage and a partnership with Invenergy, they are one step closer to that goal.
