Madison Gas and Electric seeking approval for 20MW US solar array and 40MW BESS

May 14, 2024

Madison Gas and Electric (MGE) is seeking approval from the Public Service Commission of Wisconsin (PSCW) to build a 20MW solar array and 40MW battery storage system in Fitchburg.

The Sunnyside Solar Energy Center project will be located on about 125 acres off of Whalen Road in Fitchburg.

The 20MW of solar capacity is expected to generate enough electricity annually to serve about 6,000 households, MGE said. The 40MW battery storage system will have a four-hour duration.

EDF Renewables is the project developer. If approved, construction could begin in 2025, and both the solar array and battery storage system could begin operations by late 2026.

Jeff Keebler, MGE chairman, president and CEO, said: “MGE continues on our path toward deep decarbonisation to achieve net-zero carbon electricity. Carbon is our target, and our carbon reduction goals are aligned with science. Under our commitments, by 2030, MGE expects to deliver electricity with 80 per cent fewer carbon emissions to every MGE electric customer. Similarly, by 2050, we expect to deliver net-zero carbon electricity to every MGE electric customer. We’re decarbonising our grid cost-effectively for the benefit of all customers.”
