Madison Gas and Electric (MGE) is seeking approval from the Public Service Commission of Wisconsin (PSCW) to build a 20-megawatt (MW) solar array and 40-MW battery storage system in Fitchburg, according to a recent press release. The Sunnyside Solar Energy Center would provide locally generated solar energy to MGE’s distribution system.
The project would be located on about 125 acres off of Whalen Road. The 20 MW of solar capacity is expected to generate enough electricity annually to serve about 6,000 households. The 40 MW of four-hour battery storage will provide electricity during times when energy demand is greatest and solar and/or wind is insufficient to meet all customer needs.
EDF Renewables is the project developer. If approved, construction could begin in 2025, and both the solar array and battery storage system could begin serving customers by late 2026.
