Wisconsin Energy Storage Policy and Market Overview

The energy storage market in Wisconsin is youthful and developing. Utility actions and swift regulatory approval are leading deployment. Wisconsin’s energy storage and solar markets are heavily integrated and positioned for long-term complimentary growth.

Wisconsin regulators and utilities are working to provide a robust solar-plus-storage capacity. As of 2023, the PSC approved 488 MW of grid-scale battery energy storage, and an additional 617 MW is awaiting review. Currently, all grid-scale battery storage is on-site with solar-PV. Net metering configuration in the state incorporates battery storage as a supplemental compensation to solar-PV, encouraging an intrinsic market relationship between the two technologies.

State funded grant programs and net metering are successfully providing financial assistance for community and residential deployment. While the energy storage market is growing, program design codifying key principles like equity, and BTM and FTM incentives can forge a competitive storage market in Wisconsin.
