Milwaukee, WI, August 3, 2026 —
American Transmission Co. (ATC) and We Energies have submitted a joint application to the Public Service Commission of Wisconsin for approval of a transmission charge agreement. The agreement is tied to Microsoft’s data center development in Mount Pleasant.
The core purpose of this proposed agreement is to protect existing utility customers from bearing the potential transmission costs that could arise from the energy demands of the new data center. Specifically, the agreement is designed to mitigate costs if the Microsoft facility uses less transmission capacity than initially anticipated.
The filing comes as ATC is engaged in substantial investments in transmission infrastructure. The company is undertaking upgrades estimated to cost over $2 billion. These extensive upgrades are intended to accommodate and support the growing demand for data center development throughout Wisconsin.
Further details regarding the specifics of the charge agreement, including the exact terms and conditions, have been filed with the Public Service Commission of Wisconsin. The commission will review the application to determine if the proposed arrangement meets regulatory requirements and serves the public interest.
