PORT WASHINGTON, Wis. (CBS 58) — Project leaders from Vantage Data Centers, OpenAI and Oracle were in Port Washington Thursday night to meet face-to-face with residents and answer questions about the $15 billion data center campus being built in the community.

"People are obviously curious. This is changing their community, and it is a large project," Vantage Vice President of Public Policy Misty Allen said. "In fact, it's a $15 billion economic development investment. It's the largest in the history of the state of Wisconsin."

The data center campus will include four main buildings and is scheduled to be completed in 2028.

"We will have over 4,000 construction workers on that site, and in fact, we've hit nearly 3,000 already at one time," Allen said.

Christina Pattengale attended Thursday's event with questions for the companies behind the data center.

"Living in Wisconsin, we have a beautiful environment and area, and having that being taken at one by a data center, and then obviously they're gonna be connected to the power grid," Pattengale said.

Allen said residents will not pay additional costs for the project's electricity infrastructure.

"We take a responsible growth approach. We pay all of our own electricity costs," Allen said. "None of those costs will be passed on to ratepayers."

Residents have also raised concerns about water use at the facility and how much water the campus will require on a daily basis.

Vantage says the campus will use a closed-loop water system and estimates its daily water use will be equivalent to about 65 homes.

"I think they're learning as we're learning, so I just hope we continue to stay informed," Pattengale said.
