Our Lighthouse campus is setting the standard for sustainable data center construction. Unlike traditional data centers that use significant amounts of water for cooling, this project will use a closed-loop cooling system, meaning much less water is needed than a traditional evaporative cooling system. The peak daily water use of the campus will be less than 22,000 gallons, equivalent to approximately 65 residential homes. We will not withdraw water directly from Lake Michigan; instead, we will utilize the existing city water supply.

Vantage is funding all electrical infrastructure upgrades. We’re actually adding new power capacity to the grid for the campus in addition to 600MW of clean power to be used by Wisconsin residents, with 70% of our capacity originating from zero-emission resources (the remaining 30% will be matched with renewable energy purchases).

Utility rates will not increase on other ratepayers due to our project.

Port Washington residents will see property tax savings of approximately $170 per year. The city will receive $650,000 annually in new tax revenue for schools and community initiatives.

More than 4,000 construction jobs over three years, the majority of which will be union, plus 1,000+ permanent full-time positions (including Vantage and the customer) once the campus is operational. The project will also support nearly 6,000 indirect jobs and results in an estimated $2.7 billion increase in regional GDP.

We’re setting new standards for sustainable data centers with 70% clean energy, minimal water use and comprehensive biodiversity improvements. We have carefully designed the campus to minimize wetland impacts, and we will exceed regulatory requirements for mitigation.

Construction is expected to begin in October 2026. All four buildings are expected to be operational in 2028.

No. Water use from the wells during construction will be temporary, limited and carefully managed. Two existing wells on the property will support office trailers, drawing a modest amount of water each day to two holding tanks with a maximum capacity of 6,000 gallons each, both of which will be metered. These wells are already in place, will not be expanded or upgraded to high capacity, and will only be used during the construction phase until City water is brought to Lake Drive in 2027. At that time, these two wells will be capped.

Long-term, the campus will rely on the City’s municipal water system, not on wells or the local aquifer. In addition, Vantage is investing in upgrades to local water and utility infrastructure that will benefit the broader community.

In short, this is a short-term, low-impact use of existing wells, with a long-term approach focused on strengthening City services.
