Wisconsin utility regulators voted Oct. 15 to conditionally approve two Invenergy natural-gas plants, while warning that the legal process limits their review of project need and cost. The Public Service Commission’s statement describes its preliminary votes—not a substitute for the written final orders.
The projects are Foundry Ridge, with up to 324 megawatts in Darien, Walworth County, and Red Oak Ridge, with up to 1,186 megawatts in Paris, Kenosha County. Together, their proposed capacity is about 1.5 gigawatts. The smaller project includes three gas turbines and associated transmission facilities; the larger also requires transmission connections and water infrastructure.
What the vote does not establish
The commission says both applications used the merchant-development process for non-utility power producers. Although applicants must meet a public-interest standard, state law does not require these projects to demonstrate reasonable public need or allow the same consideration of alternative supply and economic factors, including cost. Chair Summer Strand said changes to that framework would be a matter for lawmakers, according to the commission’s explanation.
That is different from finding the plants unnecessary—or determining what customers should pay. The PSC’s project guidance says costs to Wisconsin utilities and ratepayers would be reviewed if a Wisconsin utility buys a facility or its power. Wisconsin Public Radio reported Monday that We Energies has applied to acquire the plants. That creates a separate regulatory question from Invenergy’s construction applications. WPR reports targeted operation in 2028 for Foundry Ridge and 2030 for Red Oak Ridge.
Air permits remain a separate process
The Department of Natural Resources has scheduled a virtual Foundry Ridge hearing for Nov. 10 at 10:30 a.m. on its air-pollution permit application. Its notice identifies the proposed Darien peaking facility and provides online and telephone participation instructions. Residents following environmental permitting should use that notice rather than assume the PSC vote completed every required review.
The PSC statement likewise says the applicants must obtain DNR air-pollution permits. It also explains a constraint on its own public-interest analysis: commissioners cannot reject a project because of air-pollution impacts if it is permittable by DNR.
Reliability arguments and unresolved consequences
WPR reported a unanimous vote and competing views about the projects. Invenergy development executive Daniel Runyan described them as additions supporting reliable electricity and jobs. Union of Concerned Scientists analyst Maria Chavez warned about costs, air pollution and adding gas generation to serve data-center demand. Those remain attributed assessments, not proof that a particular household’s bill will rise or fall.
For now, the next documents matter. The PSC notice says final orders will contain its official action and were expected in the coming weeks. The vote therefore advances the projects, but it should not be read as a settled answer on future utility ownership, customer charges or completion of separate environmental permitting.
