After regulators told it to go back to the drawing board, American Transmission Company has reapplied to build a more than $2 billion transmission project that will serve the data center being built in Port Washington.

The utility has filed a new application with the Public Service Commission of Wisconsin to build the Ozaukee County Distribution Interconnection Project. It would include new and rebuilt high-voltage power lines, upgrades to existing facilities and construction of up to five new substations.

The project would extend across Fond du Lac, Calumet, Manitowoc, Ozaukee, Sheboygan and Washington counties. It would serve Oracle’s data center campus in Port Washington.

Bottom of Form

American Transmission Company had to file the new application after the PSC voted to revoke a “completeness” determination for the company’s previous application to build the project. Regulators felt the application had seen such extensive revisions that it became difficult for officials and the public to adequately review.

In a statement, Jared Winters, Executive Vice President and Chief Assets Officer for ATC, said the company “substantially improved” its application since its last filing and made changes based on feedback from the commission and public.
