A $1.4 billion transmission line project is being proposed to help support a planned data center development in Port Washington. American Transmission Company wants to build new transmission lines, rebuild existing lines, and build new substations across several counties, according to a recent application with the Public Service Commission of Wisconsin. The project would help meet the energy demand for a data center development in Port Washington.

“The Project is needed to reliably serve a load interconnection request by We Energies to serve a new large load addition in the Port Washington area,” the application said.

The four data center buildings are expected to need 1.3 gigawatts of electricity.  The developer behind the project is Vantage Data Centers.
