Iowa’s economic development agency is funding research into new forms of battery storage to help unlock wind potential.
Industry groups argue that even batteries that don’t meet the 10-hour threshold still provide the same reliability benefits as fossil fuel power plants.

The recommendations are contained in an energy storage report stemming from the state’s 2016 energy plan.
The rural electric cooperatives are testing how the storage technology can help customers and their systems.
