Wisconsin Institute for Law and Liberty argued that transmission line plans would destroy the landscape that shaped Tom Uttech's artistic career
Vantage Port Washington Data Center
A Vantage data center in Port Washington faces disputes over energy cost allocation, a state regulatory rejection of its power line project, and an environmental lawsuit filed against the Wisconsin DNR over the project's environmental review. It is being built, as reported August 6, 2026.
How much water it would use and who would use it have not been disclosed.

Where sources give different figures, each is shown with who gave it, and another source's figure never stands in for the record's own.

The developer's figure is what the company said; what a permit allows is the ceiling a permit sets; measured means observed. Water is in gallons a day or a year, whichever the source stated; a tax claim given as a range shows both ends, each linked to the source that gave it.
