Data center critics alarmed by ATC’s plans to add $2B+ in transmission infrastructure

American Transmission Company (ATC) plans to invest over $2 billion in new transmission infrastructure across Wisconsin to serve data centers, including those for Microsoft, Meta, and Vantage. Critics, such as the Citizens Utility Board, are concerned that the current cost-sharing structure will burden other ratepayers, while utilities maintain data centers will fully cover related transmission expenses. The Public Service Commission and FERC are involved in ongoing tariff cases to determine how these costs will be managed.
