Wisconsin Electric Power Co

Wisconsin Electric Power Co (WEPCO) is a subsidiary of WEC Energy Group, formed through mergers dating back to the 19th century. WEC Energy Group, headquartered in Milwaukee, Wisconsin, was created in 2015 via the combination of Wisconsin Energy Corporation and Integrys Energy Group. The utility has operated under its current regulated structure for over a century, serving residential, commercial, and industrial customers. The company’s capital deployment focuses on maintaining and upgrading its generation, transmission, and distribution infrastructure. Over the past decade, WEC Energy Group has invested roughly $20 billion in its regulated utilities, including WEPCO. These investments target grid modernization, renewable energy additions (solar, wind), and compliance with state-level clean energy mandates. Notable projects include the 2023 completion of the 200 MW Paris Solar Park in Kenosha County. WEC Energy Group also operates non-utility businesses, including We Power, which owns and leases generation assets to WEPCO, and a regulated gas distribution segment. WEC Energy Group employs over 7,000 people and operates seven utility subsidiaries across four states. WEPCO itself is the largest of those utilities. In February 2024, WEC Energy Group announced plans for a 10-year, $20 billion capital investment plan for its utilities, with a focus on renewable generation and battery storage. The company also maintains a philanthropic arm, the WEC Energy Group Foundation, funded with roughly $15 million annually (per the firm's 2023 corporate responsibility report). The structural differentiator for Wisconsin Electric Power Co is its vertical integration within the WEC Energy Group, combining generation ownership, distribution, and regulated retail operations. This integrated model allows WEPCO to balance capital recovery through regulated rates with long-term asset planning. Its subsidiary status also provides access to parent-level debt markets and utility-scale project financing, reducing standalone risk.
