After regulators told them to go back to the drawing board in September, 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 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.

American Transmission Co., or ATC, 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.

He said that resulted in an updated project design and power line routes.

“The revised route configuration reflects additional feedback, analysis and routing and siting work, and we believe it represents the most responsible, buildable and electrically sound option for serving this significant new electric demand,” Winters stated. “We appreciate the input we’ve received and will continue that engagement as the PSCW review process moves forward.” 

According to the application, the project would cost between $2.48 billion and $2.72 billion.
