Asset Acquisition [Abstract]
Asset Acquisition [Text Block]	ACQUISITIONS Pending Acquisitions of Electric Generation Facilities in Wisconsin We filed for PSCW approval to purchase a 30% ownership interest in Weston Generating Station Unit 4, an approximately 500 MW supercritical pulverized coal base load electric generating facility located in the Villages of Kronenwetter and Rothschild, Wisconsin and the Town of Knowlton, Wisconsin. WPS currently owns a 70% interest in this facility. Pursuant to the asset purchase agreement, we would purchase the remaining 30% interest currently owned by an unrelated third-party for its book value at the closing date, currently estimated at $150 million. If approved, it is anticipated that the transaction would close by the end of 2026. In December 2025, we, along with WPS and an unaffiliated utility, signed an agreement to acquire Whitetail Wind Energy Generation Facility, a wind-powered electric generation project with a total capacity of 67.2 MW. This project has been approved by the PSCW and will be located in Grant County, Wisconsin. We will own 80% and our portion of the purchase price is expected to be approximately $178 million. The project is expected to close in late 2027 and it is expected to qualify for PTCs.
