Port Washington AI Data Center Transmission Lines

planning

The project involves building new extra high-voltage transmission lines to serve a new mega AI data center under construction by Vantage Data Centers in Port Washington, Wisconsin. The American Transmission Company (ATC) proposes to construct these lines through greenfield areas in western Ozaukee and eastern Washington counties, which has generated public concern and opposition due to environmental and cultural impacts. The project cost is estimated between $1.36 billion and $1.64 billion depending on the final route selection.
