Port Washington
Vantage Data Centers, working from land assembled by Cloverleaf Infrastructure, broke ground in December 2025 on a data center campus on the north side of Port Washington that could grow to as much as 1,900 acres and around 3.5 gigawatts of power, potentially the largest single electricity user in Wisconsin. The project is linked to OpenAI and Oracle's Stargate initiative. In August 2026, 66 percent of Port Washington voters approved a ballot measure requiring voter approval before the city can grant future tax incentives over 10 million dollars to developers.
Power bills in Ozaukee County
Most of the county is served by We Energies.
We Energies is asking the commission for a 9.3% residential increase (We Energies general electric and gas rate case for 2027 and 2028 (docket 5-UR-112)). On a $160 monthly bill that is about $13 to $17 a month. This tariff does not change home electric rates by itself, but it is meant to make large new data centers pay the full cost of the power plants and lines built to serve them instead of spreading those costs across everyone's bill. Transmission upgrades like this are typically billed to every electric customer in the state through transmission charges, not just to the data center that made the new line necessary, which is why the cost allocation question matters for ordinary bills even outside the four counties involved.
We Energies filed a new general rate request in April 2026 seeking about 4.6 percent more on electric bills in 2027 and 4.5 percent more in 2028, plus higher natural gas charges, citing grid costs that include new power plants driven by data center growth. Consumer advocates are pushing the commission to make sure data centers and other large customers pay their share of that cost rather than residential customers. A public hearing is scheduled for September 1, 2026, with a commission vote expected in November 2026.
