Minnesota Court Halts Google’s Pine Island Data Center Build

A Goodhue County district judge has halted construction on Google’s first Minnesota data center, ordering developer Ryan Companies to stop all site work near Pine Island while the courts weigh whether the city’s environmental review skipped legally required steps. Judge Patrick M. Biren signed the temporary restraining order on Friday, May 22, blocking any pre-construction activity inside the 500-acre Project Skyway footprint about 18 miles north of Rochester.

The order, issued in response to a lawsuit by the Minnesota Center for Environmental Advocacy (MCEA, a St. Paul nonprofit law firm), arrives weeks before crews were scheduled to break ground on an 88-acre site the search giant unveiled in February as the future home of a 250,000-square-foot computing campus paired with a clean-energy deal worth roughly 1,600 megawatts of new wind and solar through Xcel Energy. Ryan Companies has told the court that every month of delay carries a price tag of as much as $5 million.

What the Goodhue County Order Does

Biren’s ruling does three things at once. It bars site work, denies the developer and the city’s motion to dismiss the case, and orders Pine Island to hand over project records the environmental group says it has chased in email requests for months without success.

In writing, the judge told the parties that “failure to comply with environmental review itself can constitute irreparable harm,” and that the challenge “would be moot if construction begins.” The plaintiff had to post only a $2,000 bond to secure the order, a modest security deposit relative to what the developer says it stands to lose.

“We’re really thrilled with their ruling,” said Joy Anderson, MCEA supervising attorney. “This will slow down this process and allow us to make our case so the environmental review for this data center can be reviewed by the court.”

City officials did not respond to a request for comment Tuesday afternoon. The October appeal filing on the Pine Island review remains the controlling document outlining what the suit demands and the procedural box the city now sits inside.

The AUAR Shortcut at the Heart of the Case

The city ran its environmental homework on Project Skyway through an Alternative Urban Areawide Review, or AUAR, a streamlined Minnesota process designed for industrial parks and mixed-use developments where the exact tenants are not yet known. Staff completed the review in early 2025, and the city council finalized it last fall.

The environmental group’s central claim is that the AUAR was the wrong tool because the city and the developer already knew who the tenant would be. The company did not publicly attach its name to the site until February, but the lawsuit alleges Ryan Companies was in active talks with the search giant when the review began, which under the group’s reading triggered a duty to run a full Environmental Impact Statement (EIS, a more demanding state-law review built for site-specific projects with a known operator).

The lawsuit lists five concrete gaps it says voided the AUAR:

• A vague project description that omitted the words “data center” entirely
• No analysis of cumulative impacts on water, electricity, noise, and light from the build
• No disclosed estimate of the facility’s peak electricity demand or fuel mix
• No study of effects on groundwater, the local aquifer, or private wells inside the review area
• Greenhouse-gas estimates published without the supporting calculations underneath them

“Environmental review is the public’s only opportunity to understand impacts before development proceeds; it cannot work when relevant details are absent,” Abigail Hencheck, a staff attorney with the environmental group, said in the October filing.

The city’s review did include mitigation recommendations. The plaintiff argues those were written as possibilities rather than binding commitments, which is short of the threshold Minnesota rules require for a project of this load and footprint.

Project Skyway by the Numbers

The data center plan, as disclosed in the company’s February 24 announcement and in city filings, is to occupy 88 acres of the broader 500-acre site with a 250,000-square-foot building along the east side of Highway 52. Power would come from Xcel Energy and water from the local municipal supply, with an estimated draw of up to 55.7 million gallons a year. That single facility would lift the city’s total water use by roughly half.

The energy side is the most aggressive part of the package. The search giant has agreed to fund 1,400 megawatts of new wind generation, 200 megawatts of solar, and a 300-megawatt iron-air battery system designed to hold a charge for more than 100 hours, far longer than the lithium-ion units utilities typically use to firm up renewable output. It is also putting $50 million into Xcel’s Capacity*Connect program to seed distributed battery storage across the utility’s territory.

What the AUAR said about all this versus what later came out in February sits at the center of the dispute. The contrast:

The 2,700-megawatt ceiling is the plaintiff’s worst-case demand estimate, not the company’s. For context, the entire residential electricity load of Minneapolis is on the order of a few hundred megawatts at peak. “This is going to be massive,” Anderson said. “It’s really critical for us to know what is going to happen when you build a 2,700-megawatt facility. We just don’t know.”

A Pattern Repeating Across Minnesota

The city is the fourth Minnesota community the nonprofit has dragged into court over data-center reviews in the last nine months, and the complaint pattern is almost identical in each: a streamlined AUAR, no named tenant, water and power numbers either missing or expressed only as ranges, and a developer with a recognizable hyperscaler in the wings.

The growing docket:

1. Lakeville, August 2025: AUAR challenge over a 4 million-square-foot technology park
2. North Mankato, August 2025: similar AUAR challenge, later dropped after the city restarted its review
3. Hermantown, October 2025: appeal that prompted the city to restart its environmental study for another Google project
4. Pine Island, October 2025: the case Biren has now allowed to proceed
5. Monticello, early 2026: lawsuit filed against that city’s review process

The state-level numbers explain why the docket keeps growing. More than two dozen hyperscale facilities are under proposal in Minnesota, and utilities have warned regulators that, if all of them connect, the combined load would rival the state’s total residential electricity demand. The plaintiff’s strategy is to force what it calls a “full” EIS on each hyperscale build, a level of review that takes longer and costs more than an AUAR but produces binding mitigation requirements rather than recommendations.

“Minnesotans have a right to know where the energy will come from to power these massive facilities and how our clean air, drinking water, and quality of life will be protected,” Kathryn Hoffman, MCEA’s chief executive, said in a statement on the multi-city data center lawsuit campaign.

The $5 Million Question for Ryan Companies

Construction crews were scheduled to begin earthwork in July. The developer told the court that holding that schedule had hinged on the city’s environmental sign-off being defensible, and that each month of delay carries the seven-figure cost cited in the lede plus exposure to lost contractor commitments and remobilization fees after the pause.

Whether the search giant itself bears any of that cost is unclear; the agreement between the developer and its client is not in the public court file. What the file does show is that the city has already approved financial incentives on the project and has counted on the data center’s tax base, which officials have said will generate tens of millions of dollars over the life of the campus without affecting local utility bills.

That tax-revenue case was the central argument city leaders made in public meetings through 2025. The lawsuit puts a different number against it: every month of paused construction is a month the tax-base assumption shifts further into the future, and a month the financing math behind the project’s incentive package gets less forgiving.

The cumulative impacts of this kind of build on water, power, and air quality have never been studied in Minnesota at the scale that’s now being proposed.

That framing, from the group’s October filing, captures why the nonprofit believes the financial pressure cuts the other way. The longer the case runs, the group argues, the more pressure mounts on the city to settle by reopening the review rather than litigating through every available appeal.

Mayor David Friese has put the worst case at pushing the project’s groundbreaking into 2027.

How the Calendar Plays Out

The next courtroom date will set the tempo. The order requires the city and the developer to produce the project records the plaintiff has requested, and the schedule on those filings will determine when the merits of the AUAR challenge come up for argument.

Three things are now on the meter:

• Discovery from the city and developer, the first batch of which is due under the order’s timeline
• The utility’s procurement schedule for the new wind and solar tied to the project, currently slated to come online in 2028 and 2029 and which a long pause could push
• Hermantown’s restarted review, which is the closest precedent for what a do-over looks like and how many months it adds to a hyperscale build

If the case settles with the city agreeing to a fuller review, the project likely still gets built, only later and with binding water and power conditions attached. If the city and developer win on the merits, the AUAR-as-shortcut model survives and the four other Minnesota cases lose their template. If the environmental group prevails outright, every hyperscale data center proposal sitting on an AUAR in the state gets rewound to the start, and the utility’s two dozen large-customer conversations across its multi-state footprint move to the back of a longer line.

The first answer comes from the discovery filings due in the weeks ahead.
