Xcel trims Ten Mile Creek solar, adds batteries
Xcel Energy canceled phase two of its Ten Mile Creek Solar project in St. Croix County, WI, proceeding with a 300‑MW first phase over 2,980 acres and adding a battery energy storage system that will interconnect via a new line to the Allen S. King site in Oak Park Heights. Xcel will file with the Public Service Commission of Wisconsin by year‑end 2025, kicking off a 12–18 month review, with construction possible in late 2027 and service by late 2029 as the coal‑fired King plant retires in 2028.
