We Energies has broken ground on three Wisconsin renewable-energy projects totalling roughly 385 megawatts of solar, wind and battery-storage capacity - enough to power about 100,000 homes and employ more than 450 construction workers.
What's being built
The utility, a WEC Energy Group subsidiary, confirmed on August 4, 2026 that Darien Battery Storage (a 75 MW facility in Walworth County) started construction last week, joining the previously-online 250 MW Darien Solar Park. Dawn Harvest Solar and Battery Park (150 MW solar plus 50 MW storage in Rock County) kicked off in June, and the 110 MW Badger Hollow Wind Energy Center in Iowa and Grant counties broke ground in July.
Invenergy's Wisconsin footprint
Invenergy, North America's largest privately held clean-energy developer, is developing and building all three sites. Invenergy has 1,500 MW of Wisconsin capacity currently under construction across 17 projects. Wisconsin Public Service and Madison Gas and Electric are minority co-owners alongside We Energies.
Grid context
We Energies now operates or has permitted more than 3,000 MW of solar and wind and 600 MW of battery storage, part of a WEC "all of the above" strategy that also includes new gas plants. Parent WEC Energy Group has flagged roughly $20 billion of capital spending across the next five years to meet Wisconsin's rising electricity demand from data centres and electrification. The move mirrors utility bets tracked in our coverage of SMR partnerships in the US Gulf South.
