Interesting to see a Utility scale storage project supporting increased rooftop solar in a neighborhood. Something you might expect in CA but this project is in Iowa.

Battery storage is needed in Decorah because one electric circuit that serves the community will start to reach capacity as more customer-owned renewables are added. Until now, energy companies have had to either upgrade the grid in a community, which was expensive, or restrict the number of solar arrays that could be added in one area. Using battery storage to meet this challenge is just one of many applications which may lower customer costs. 

“This battery project is a game-changer in Decorah,“ said Terry Kouba, President of Alliant Energy Iowa. “We’re installing it on a circuit that’s near capacity for solar. Using batteries can add critical capacity and may save our customers money, because a battery costs a fraction of the total to upgrade our system.”
