The biggest investment in our city's history. The questions deserve the same scale.

A $15 billion data center campus is rising on Port Washington's north side. Residents didn't just ask hard questions about water, power, and who actually benefits — they forced the first data-center referendum in the country. This page lays out what's known from public records, makes the case for getting it right, and says plainly where the project still has to earn the city's trust.

Where we agree

You don't get to take the power and the water and keep the details quiet.

The residents who packed council chambers — and then gathered the signatures for a referendum — were right about the thing that matters most: a project this large has to prove it will protect Lake Michigan's water and the local grid, and it has to do it in the open. Transparency about water, power, and incentives isn't an obstacle to development. It's the price of admission.

So this page supports the opportunity and insists on the openness. Every claim below links to a public record you can check yourself — local reporting, the developer's own filings, and City of Port Washington documents. Where the project still has to earn trust, we say so.

The questions, answered

Five concerns raised in Port Washington — and what the record says

Each card states the concern as residents actually raised it, gives the most accurate answer available today, and links you to the primary source.

Q1Verifiable fact — with a real caveat

"How much water will this pull from the lake, especially on the hottest days?"

This is the question people picture first, and it deserves a precise answer. Vantage says the four buildings will use a closed-loop liquid cooling system designed to recirculate water and use minimal amounts, and its North America president has called Lighthouse a "very water-sustainable campus." The company has also pledged $3 million to the Lakeshore Natural Resource Partnership toward water-positive restoration of the Valley Creek corridor.

The honest caveat raised by Clean Wisconsin is the right one: the figure that matters isn't an average — it's peak demand on the hottest, driest days, plus the water used by whatever power plants feed the campus. Those numbers belong in a public file before anyone calls the question settled.

Q2Context — verify the final terms

"Up to 902 megawatts. Who pays for the grid, and will my bill go up?"

The scale is genuinely enormous — close to a gigawatt across four buildings — and pretending otherwise would be dishonest. The protection residents should demand is the one being adopted across the country: the large-load customer pays for the grid upgrades the project triggers, rather than shifting those costs onto households. OpenAI's own announcement claims the campus will expand capacity "without raising rates for local consumers," and We Energies says it is adding generation to serve the load.

Whether that promise holds depends on the interconnection terms and the new high-voltage transmission lines and substations — which face separate review by the Public Service Commission of Wisconsin, where routing and reliability have already drawn objections. Those terms should be public before they're final.

Q3The defining fact of this project

"Why did residents have to force a vote just to be heard?"

This is what makes Port Washington a national story, and it has to be named plainly: residents passed the first referendum of its kind in the country, requiring voter approval for large-scale data center projects that receive tax benefits. It passed by a lopsided margin. The resident group Great Lakes Neighbors United argued the tax-increment district had been "marched ahead and passed" with little community input — which is exactly the gap a referendum exists to close.

A project that's confident in its benefits should welcome that scrutiny rather than fight it. The standard this page holds is simple: name the operator, publish the terms, and treat a public vote as legitimacy, not as a threat to investment.

Q4Context — verify the local figures

"A $175 million TID — is the city on the hook, and do the benefits reach us?"

Here's how the financing actually works. The city created Tax Incremental District No. 5, and Vantage pays the roughly $175 million in up-front infrastructure costs — water and sewer mains, road work, a new water tower — and is reimbursed over time from the new property taxes the campus itself generates. The district captures that new value rather than drawing on existing tax bills. Vantage and Oracle project more than 4,000 construction jobs and over 1,000 permanent jobs once operational.

The honest version: those job and investment figures are projections, and like all data centers the permanent on-site headcount is modest relative to the dollar size. The numbers that should decide it — confirmed local hires, payroll, and the value of the incentive against what the city forgoes — belong in plain language residents can read.

Editor — insert confirmed local figures. When the city or Joint Review Board publishes verified permanent-job counts, payroll, and the final TID No. 5 reimbursement schedule, add them here with a source link. Until then, label jobs and investment as Vantage/Oracle projections, not settled facts.
Q5In progress — public process underway

"It already broke ground — is anything still up to us?"

Two things are true at once. Construction began in December 2025 and the first phase is moving forward; at the same time, the project remains genuinely contested — there are active lawsuits over the referendum ordinance and the TID, and the city is still annexing the broader area in phases. No plans have been announced for roughly 1,200 of the nearly 1,900 acres beyond the first four buildings.

So the leverage that remains is real: the referendum governs future tax-benefit projects, transmission routing is still before the state, and the terms of any future phase are unwritten. The window to set enforceable standards — on water reporting, ratepayer protection, and disclosure — is the one residents fought to keep open.

What's actually being built

The Lighthouse campus, by the numbers

Named for Port Washington's own lighthouse — here's the project as documented by the developer, the city, and local reporting.

$15B+
Total investment — one of the largest economic projects in Wisconsin history
672 acres
Campus near Interstate 43; 500 developed, 172 preserved for biodiversity
~902 MW
Capacity across four single-story data centers — close to a gigawatt
2.5M sq ft
Four buildings of data halls for AI and cloud computing
$175M
Tax Incremental District No. 5 for infrastructure, repaid from new value
2028
Targeted completion; ground broken December 2025

Developer: Denver-based Vantage Data Centers, with OpenAI and Oracle as end users under the federal Stargate program. The campus sits within a broader ~1,900-acre area being annexed into the city in phases; no plans have been announced for roughly 1,200 of those acres. Figures should be updated as city and Joint Review Board records become available.

How we got here

From quiet approval to the country's first data-center referendum

The order of events tells the story: the campus was approved and broke ground first — and the community's push for accountability escalated from there. Each entry links to the public record.

January 2025

First public mention

A proposed data center surfaces in a Common Council working session. The city begins fielding resident questions and publishing a running FAQ.

The nation's first data-center referendum passesLandmark

By a lopsided margin, voters approve a first-of-its-kind ordinance requiring voter approval for large-scale data center projects that receive tax benefits. A business group's bid to halt the referendum is denied; the group later sues over the ordinance. Statewide, the share of Wisconsin voters who say these projects' costs outweigh their benefits jumps from 55% to 70% — the biggest shift in 14 years of Marquette Law School polling.

No spin

The real tradeoffs, stated plainly

A site that pretends a project this size is all upside isn't informing anyone. Here is what reasonable people in Port Washington are actually weighing.

The power load is immense.Roughly 902 MW requires major new transmission and substations. The interconnection terms must keep grid-upgrade costs off residential bills — and prove it in the agreement, not the press release.
Water is reduced, not zero.Closed-loop cooling is a real improvement, but peak-day demand and the water used by the power source still belong in a public file — exactly what Clean Wisconsin has asked for.
Permanent jobs are modest.The construction workforce is large and union-built; the lasting on-site headcount is smaller relative to the investment. The case rests on tax base and infrastructure as much as payroll.
Transparency had to be forced.Residents passed the first referendum of its kind to win a say. Accountability is now on the table — but the fact it took a ballot measure is itself the lesson.
Annexation is a long-term change.Moving ~1,900 acres from township to city in phases reshapes land use and tax status for years. The plan for the unbuilt ~1,200 acres is still unwritten.
Local control has limits.Transmission siting sits with the state Public Service Commission, not the city — which is why a strong, lawful local framework and state-level advocacy both matter.

Our vision for Port Washington

A harbor town that's always built things. Let's make sure we own a share of what's next.

Port Washington built its identity on the lakefront — the harbor, the power plant on the point, the lighthouse that gives this campus its name. The age of artificial intelligence is the next thing worth building, and a data center done the right way — with the water protected and the books open — can anchor the city's place in it. Not just a campus of servers, but the power, fiber, tax base, and investment that strengthen our schools, our hospitals, and the public services every family relies on. The AI economy will be built somewhere. Port Washington has every reason to claim part of it — on our terms.

01 · Jobs

Careers that anchor families

Thousands of union construction jobs now, through the Wisconsin Building Trades Council, and skilled operations roles after — plus the infrastructure that draws the employers who follow.

02 · Public services

Revenue residents can feel

New value in TID No. 5 eventually flows to schools, police, fire and EMS — funding services without leaning harder on existing household tax bills.

03 · Universities

Research & talent that stays

Computing capacity and partnerships with UW-Milwaukee, MSOE and Concordia that give southeastern Wisconsin's students a reason to build their futures here.

04 · Health

Hospitals & medical innovation

The regional infrastructure Aurora, Froedtert and area medical systems can draw on for AI-assisted diagnostics, research and better patient care.

05 · Lake-smart growth

Recirculate, don't waste

Closed-loop cooling, 172 preserved acres, native plantings and the Valley Creek restoration pledge can make this a model for water-conscious growth on the lakeshore.

06 · AI economy

A seat at the table

AI is reshaping every industry. Local compute means Port Washington helps build that future instead of renting it from Virginia or Texas.

The opportunity is real — and so are the conditions. Protect the water, open the records, honor the vote, and the city can move forward with confidence: built right, and built here.

Make it official

Tell your council: support responsible development — with the water protected and the records open.
