• Jobs for data centers happen in three phases: development, construction and operations. 

• The largest numbers of workers are on site when a data center is being built, experts said. 

• The number of long-term jobs a data center brings depends on the size of the facility. 

• It’s difficult to measure the ripple effects data centers have on the economy; however, experts say local businesses can benefit from producing components and products for data centers. 

• Data center technicians will be in high demand as more facilities come online.

As data center developers stake out land in Wisconsin communities, much debate has surrounded whether the computer-packed warehouses will deliver economic benefits locally. 

Waves of opposition and concerns about land, water and electricity use routinely follow data center proposals, while supporters echo that the centers will create jobs and help the economy. 

But what jobs? How many of them? And will they last?

To answer those questions, Wisconsin Watch talked to three professors:

• Xiaofan Liang, who specializes in urban and regional planning at the University of Michigan.
• Scott Adams, a University of Wisconsin-Milwaukee labor economist. 
• Dijo Alexander, who specializes in information technology, digital transformation and artificial intelligence at the University of Wisconsin-Milwaukee. 

Here are some takeaways.

What kinds of jobs do data centers bring?

Data center jobs fall into three major categories that represent phases in their creation: 

• Development
• Construction
• Operations

A data center first needs people to plan for its existence. Developers, engineers, designers and planners lay that groundwork. 

“The data center industry as an ecosystem is pretty big … When they first introduce a data center to a place, they have to figure out the design standard, how to construct all kinds of facilities, how it connects to city systems,” Liang said.

Then, developers must hire heaps of hands-on laborers to construct the gigantic warehouses from the ground up — the largest portion of workers needed in creating and operating a data center. Among other professions, this includes electricians, plumbers and pipefitters, carpenters, structural steel and iron workers, concrete workers and earth drillers.

The job boom from early phases fizzles out once the building is complete, Liang said. 

“(During) construction time, you usually have a lot more jobs — maybe 10 times in magnitude more so than operations,” Liang said. 

Operations jobs, fewer in quantity, are largely “unglamorous,” Adams said. 

Some of these roles have relatively low barriers to entry, such as maintenance workers and security guards. Meanwhile, electricians and HVAC workers are needed, considering that power and cooling are data centers’ “two most important inputs,” Adams said. 

Adams echoed a popular analogy likening data centers to warehouses full of rotting bananas that need constant cooling and replacing.

“You need banana technicians, more or less, that take the rotted bananas out and replace them with new bananas,” Adams said. “Now, granted, they’re much more expensive bananas in there, and they’re doing a whole lot, and it requires a little more expertise. But again that expertise, by and large, can be developed pretty quickly.”

Those workers will be data center technicians — people who install servers, replace hardware and cables, monitor systems and notice when things break down.

How many jobs do data centers bring? 

The number of jobs created depends on a data center’s size, Liang said.  

That can initially mean thousands of jobs at gargantuan developments like in Mount Pleasant. Microsoft says it has employed 3,000 people to construct the location, compared to 500 full-time workers once the plant is operating. But these numbers are expected to climb as the company constructs a cluster of additional centers at the site. 

Not all of these workers will be local. Given the temporary high demand, the projects will likely need out-of-town construction laborers who travel to the area and don’t stay long term.

Smaller projects will employ far fewer people. For a typical data center, Microsoft estimates it hires about 50 full-time employees. What those numbers mean for the local area depends on the community’s size. 

“In a bigger city, like Atlanta, it’s like a drop in the ocean, right? It doesn’t really affect much,” Liang said. “In a rural area, in a smaller town, hundreds of jobs … are a big deal.”

What about the trickle-down economic benefits? 

A sizable new employer entering communities could ripple across other nearby industries, though Liang notes this is hard to measure. 

“(A data center) just has such a big infrastructure need that trickles down in many different ways,” Liang said. “Now we need expanded utility infrastructure, grid, fiber, water, all these things. Construction of these infrastructure, even though it’s not directly related to (a) data center, could increase local employment in those areas.”

Inside a data center are “cabinets after cabinets of steel frames holding computers” that need to be built, Alexander said. This can boost local manufacturing, especially the metal fabrication industry. 

Wisconsin manufacturers have already begun cashing in on the construction boom nationwide. As Wisconsin Watch previously reported, just three Wisconsin companies alone have amassed more than $1 billion in equipment sales — such as motors, generators and cooling systems —  to data centers.

Massive developments like Microsoft’s in Mount Pleasant can potentially lead to a “tech corridor,” a cluster of warehouses and manufacturers near the data center they serve, Alexander said. 

“If we take the initiative and if we bring a few big enough component manufacturers, we can create locally created components for these data centers to consume,” Alexander said. “It’s like if you have a big restaurant or food manufacturer here, you will have agriculture around there, because it is easy for you to bring your produce for their consumption. Just like that. ”

The trend could also activate industries like nuclear power, Adams said. Building data centers  in conjunction with nuclear reactors to generate their power would fuel even more construction and energy jobs, he added. In Kewaunee County, an energy company wants to rebuild Kewaunee Power Station, a defunct nuclear power plant, anticipating energy demand from AI and data centers.

In more rural communities or near smaller data centers, the trickle-down effects could prove more modest — perhaps a few new restaurants and housing units, Adams said. 

Alexander also noted the effects could also be less concentrated, with growth spilling into neighboring cities as employees work at the center but live elsewhere.

But will enough permanent jobs be created to sustain the growth sparked during the early labor-intensive development phase? That’s unclear, Adams said. 

“We don’t have a firm enough grasp about the indirect effects in the longer term,” Adams said. “Short run, that’ll be great. Longer run, can we sustain the new development that might happen around these? I don’t know the answer to that. I think if the power generation side of it comes in connection with them, there’s more of a chance that that will work.”

Who are data center technicians?

Data center technicians are perhaps the most novel job introduced by the data center boom. The roles are more specialized than others needed inside the warehouses.

Job postings for data center technicians at Microsoft’s Milwaukee location say the workers will be “preparing, installing, performing diagnostics, troubleshooting, replacing, and/or decommissioning equipment under the guidance of more experienced data center colleagues.” 

The posting states the job requires a high school diploma, knowledge of computer hardware and some experience with IT equipment. Pay for lower-level technicians ranges from $23 to $36 per hour, with more experienced workers making up to about $48 per hour.

Adams said likely candidates will include engineers and computer coders and people now entering college with their sights on data center work. Microsoft and Gateway Technical College in Kenosha launched a “Data Center Academy,” preparing students to work in data center operations. Adams believes partnerships like this will become more common.

Microsoft data centers in Mount Pleasant in southeast Wisconsin are projected to use much more water annually than would fill four Olympic-size pools.

Water to operate the facilities, including for cooling, will be supplied by the city of Racine.

The first data center, described by Microsoft as “the world’s most powerful data center,” is expected to begin operation in 2026.

Racine projects that facility will use 2.81 million gallons of water (roughly four Olympic pools) in 2026.

But a second data center is also under construction and a 15-center expansion is planned.

Racine projects total water usage will be 8.44 million gallons annually (roughly 12 pools).

The projections don’t include water that will be needed to generate electricity to fuel the data centers.

The Lawrence Berkeley National Laboratory estimated in 2024 that 92.5% of the water U.S. data centers used was to generate electricity, 7.5% for cooling.

This fact brief is responsive to conversations such as this one.

• At least five Wisconsin communities have signed nondisclosure agreements with data center developers, including the town of Beloit.

• Even in communities without an NDA, there has been pushback against transparency. For example, Port Washington was sued because it released emails referencing a project, but not the attached files.

• It’s unclear if the state Senate will take up a bill that would ban data center NDAs, but the Assembly has already adjourned without passing the bill.

At a Jan. 28 public forum on Wisconsin data centers, Port Washington Mayor Ted Neitzke boasted that his city did not sign a nondisclosure agreement that would have concealed plans for a $15 billion facility that is now under construction.

“If you’ve got the courage and you push back and say, ‘Listen, we’re just not going to do it,’ (the data center developers) will find a way to operate without having to sign an NDA,” Neitzke said. “So, we did not and we will not.”

On the same day Neitzke was touting his community’s openness, Port Washington was in court over its refusal to provide communications about its data center. The city had turned over emails, but not documents attached to the emails.

It’s one example, beyond NDAs, of local governments hiding details of proposed large-scale AI data centers, which are projected to span hundreds of acres, cost billions of dollars and transform communities.

Wisconsin Watch reported in January that NDAs were signed in at least four Wisconsin communities where artificial intelligence data centers are proposed or being built — Beaver Dam, Kenosha, Janesville and Menomonie. Since then, Wisconsin Watch has learned about a fifth project with an NDA, this one in the town of Beloit — showing that discussions there occurred more than a year before any public announcement was made.

Port Washington stymies public records requests 

Construction began in December on Lighthouse, the 672-acre Vantage-OpenAI-Oracle data center campus in Port Washington, north of Milwaukee.

Four months earlier, philanthropist Lynde Uihlein, a town of Port Washington resident, environmentalist and major Democratic donor, made a public records request of the city. She asked for any communications between the city and the data center developer dating back to Jan. 1, 2025.

The Wisconsin public records law declares that “all persons are entitled to the greatest possible information regarding the affairs of government” and that governmental bodies must respond to requests “as soon as practicable and without delay.”

After nearly three months, the city did not reply to Uihlein’s request, so she sued.

The city responded by turning over emails, but not the documents attached to those emails, such as a draft development agreement. The city’s attorney explained that Uihlein didn’t specifically ask for the attachments.

“When cities want to court large, community-changing development, they also should be prepared to act with maximum transparency,” said Madison lawyer Christa Westerberg, one of the lawyers representing Uihlein.

“The city of Port Washington has been too slow to respond to requests about the data center and even when it has, there are gaps, like providing emails without attachments. This was foreseeable and avoidable.”

Wisconsin Watch is one of Westerberg’s clients, but is not a party to this case. Westerberg did not participate in the writing or editing of this report.

City Attorney Matthew Nugent told Wisconsin Watch: “The assertion that the city refused to produce email attachments is inaccurate. The city reasonably interpreted the original request to seek the email communications themselves, that is, the body of the email message, not the separate documents attached to those communications.”

At a court hearing Jan. 28, Ozaukee County Circuit Court Judge Adam Gerol rejected the idea that documents attached to emails aren’t part of the emails themselves. “There has not been a complete response to the open records request,” he said.

In February, the city turned over emails along with attachments to Uihlein, and Gerol ruled that city officials must submit to depositions to answer questions from Uihlein’s lawyers.

Gerol will be asked to determine whether the city has fully complied with the public records law, whether its delay in replying violated the law and whether it should have to pay Uihlein’s legal fees.

Another denial

The city used the same rationale to partially deny another public records request.

Port Washington resident Michael Beaster, an opponent of the data center, asked the city Nov. 20 for emails and other communications between city officials and the data center developer. 

The city replied six weeks later, sending some emails but no attachments to the emails. An attorney for the city told Beaster he would need to submit another request if he wanted attachments because Beaster did not specifically request those.

“It feels like they’re being overly cautious in trying to protect the city,” Beaster said, “which certainly isn’t serving the public.”

Beaster is running unopposed April 7 for an open seat on the Port Washington city council. He helped lead a failed effort to recall Neitzke over the data center.

Neitzke said he could not comment on why the city has not turned over email attachments, other than to say he is not part of the process of releasing records.

NDA for possible Beloit data center

News surfaced this month of a possible data center an hour southeast of Madison in the town of Beloit. The town, saying it was responding to information “being disseminated” about a possible data center, announced it had begun “very preliminary discussions” and signed a predevelopment agreement with Delaware-based Cambrin LLC.

Wisconsin Watch has since learned that the town signed an NDA with Cambrin in February 2025 — more than a year before making its announcement.

The NDA and other documents provided to Wisconsin Watch in response to a public records request do not directly refer to a data center. 

The documents indicate that “Project Corn Maze” would initially include 700,000 square feet of buildings, employ 50 people and require tax incremental financing from the town.

The records also show that the town has exchanged emails about the project since April 2025. They indicate that Cambrin LLC was formed to make the development proposal and don’t identify what company would operate the data center.

Signs of openness 

Access to records also was at issue for the first phase of a data center complex south of Milwaukee in Mount Pleasant. The first center in that Microsoft complex is expected to open later this year.

This month the Wisconsin Freedom of Information Council announced it is giving its annual citizen openness advocate award to Midwest Environmental Advocates. The public interest law firm successfully sued the city of Racine for records disclosing how much water it is projecting to provide for the Mount Pleasant data center.

The council also gave an award to Wisconsin Watch for its story on data center NDAs.

Amid reports of a possible data center in Grant County and as Meta seeks to add a data center to one it is building in Beaver Dam, there is movement toward more openness on several fronts.

The state Public Service Commission, which approves requests for new utility plants and utility rates, initially accepted a confidentiality request from Alliant Energy in its application to serve the Beaver Dam data center despite numerous redactions — including how much energy the center would use.

On Feb. 26, however, state administrative law judge Michael Newmark, who is overseeing the PSC hearings on the request, told Alliant to resubmit its request with fewer redactions. Alliant did the next day with less information blacked out. 

“It seemed like the redactions were not going to allow us to do sort of the basic functions of open government,” Newmark said at the hearing. Fewer redactions would enable the commission to rule on the application in a way that is “defensible in court and in the court of public opinion,” he said.

Last week the University of Wisconsin-Milwaukee Center for Water Policy released a model for state legislation to “promote transparency and environmental protections” for data centers.

The model, which recommends temporary statewide moratoriums on data centers, makes several recommendations to increase transparency, including a ban on local governments signing NDAs and requiring public disclosures on water and electricity use before any approvals are given.

The “continued absence of comprehensive and timely disclosure requirements,” the report said, “undermines public understanding and limits informed decision-making around siting, permitting and environmental impacts.”

And on Friday, a state Senate committee on a 4-1 vote approved Senate Bill 969, which would prohibit local governments from signing NDAs with data center developers. No further action has yet been scheduled.

The committee also advanced, 3-2, Assembly Bill 840, which would require the Public Service Commission to protect ratepayers from the costs of providing electricity to data centers. The bill contains a controversial requirement that renewable energy used for a data center be located on the site. The Assembly passed the bill 53-44 in January. 

Legislation banning NDAs is pending in several states, including two that took action last week.

A Minnesota House of Representatives committee approved a bill banning data center NDAs and sent it to the House floor.

In Florida, a provision banning NDAs that industry groups lobbied against was removed from a data center bill. 

A report released last week by the Alliance of Great Lakes urged governmental bodies to limit the use of NDAs so that the public can know how much water and energy a data center will use.

“When critical information is withheld, decision-making shifts risk from private developers to communities and public utilities,” the report said.

• While no hyperscale data centers are operating yet in the state, Wisconsin companies are helping power massive facilities elsewhere by supplying parts and equipment. 

• Just three Wisconsin companies have already amassed more than $1 billion in data center-related business. 

• It’s still unclear how much large-scale Wisconsin data centers will ultimately contribute to the state’s economy — and some question their long-term impact.

None of the billion-dollar-plus data centers planned for Wisconsin are yet online, but the nationwide, artificial-intelligence-fueled market is already spurring economic growth in the state.

Wisconsin business leaders say no comprehensive accounting has been done. But just three Wisconsin companies have already amassed more than $1 billion in data center-related business: 

• Regal Rexnord, a Milwaukee maker of motors, announced in February it had received $735 million in orders from data centers.

• Generac, a Waukesha-based manufacturer, told Wisconsin Watch it has a backlog of $400 million in orders for backup generators for data centers. Moreover, Generac announced Feb. 19 it is acquiring a 120-employee Illinois engineering company to help meet data center demand. 

• Racine-based Modine announced in February 2025 it received $180 million in orders from a new customer for data center cooling systems to be manufactured in Virginia and Mississippi. In addition, the company in November opened a 155,000-square-foot plant in suburban Milwaukee to manufacture the systems.

Many companies don’t publicly report details on data center business they do, so it’s impossible to tally total economic impact in Wisconsin. But there are other examples.

Trane Technologies is manufacturing cooling systems for data centers in La Crosse, where it was founded in 1913, and says data centers are a strong part of its business. In November 2023, Excellerate opened a 385,000-square-foot plant in Little Chute, primarily to manufacture “modular electrical buildings” for data centers. Maysteel, a Washington County manufacturer, opened a data center hub in November 2024 and announced in February it is expanding the operation. 

The sheer demand to outfit data centers has meant that some business has trickled down from larger companies to smaller ones.

Modular Power & Data has 90 employees in Dane County and suburban Milwaukee to manufacture electrical distribution products. Chief Operating Officer Erik Thompson told Wisconsin Watch that Modular did $10 million of data center business in 2025 and expects to more than double that in 2026.

That work is “transforming a very small company into what I believe will be a very large Wisconsin manufacturer,” Thompson said. “Without this growth, we’d always be much smaller.” 

Because no hyperscale data centers are scheduled to begin operating in Wisconsin until later this year, their ultimate economic impact remains unknown.

Nationally, data centers are known for spurring construction work. That includes companies such as Brownsville-based Michels Corp., a lead contractor on the $15 billion data center under construction in Port Washington, and Waukesha-based Boldt Co. But those jobs are often temporary. 

“The standard data center development model — speedy dealmaking and opaque negotiations — delivers short-term construction jobs and revenue, but little durable local economic upside,” the Washington, D.C.- based Brookings think tank concluded in February.

In Wisconsin, data center expenditures are projected to raise the state’s gross domestic product from $354 million in 2024 to $881 million in 2029, according to University of Virginia economist João-Pedro Ferreira, author of a study done for the Joyce Foundation. The data center workforce is expected to triple from 360 to 1,143 jobs, but constitute only 0.09% of the overall labor market.

“The impacts might seem a lot, but they are not,” Ferreira said.

At least $46 billion in hyperscale data centers are under construction or under consideration in Wisconsin. Besides Port Washington, $20 billion worth of data centers are under construction and planned in Mount Pleasant, and a $1 billion facility is being built in Beaver Dam. Proposals are pending in Janesville, Kenosha and Menomonie. 

That’s as concerns about impacts on land, water and electricity spur loud opposition to data centers in Wisconsin. On Facebook alone, more than 24,000 people have joined groups to fight hyperscale centers that are proposed or under construction in the state. 

But Wisconsin businesses see more growth from AI. In November, a foundation connected with Waukesha County-based Pieper Electric announced a $2 million donation to expand Waukesha County Technical College’s Applied AI Lab.

Dale Kooyenga, CEO of the Metropolitan Milwaukee Association of Commerce and a former Republican state lawmaker, said skills being developed for data center construction have value after the facilities are built.

“These men and women building these data centers aren’t building just buildings, they’re building the world’s largest computers,” he said. 

Kooyenga also pushed back on claims that AI will be bad for the economy.

“The concept that robots and technology are out to get your jobs has been a concept in America since 1900. That’s not a new fear,” he said. “But the fact is, is that there will be a different-looking economy and different opportunities.”

AI’s growth is affecting workers unevenly across industries. 

It’s reducing employment in the most AI-exposed industries, such as computer systems design, and it’s especially hitting younger workers, according to a new Federal Reserve Bank of Dallas analysis. 

But wages in those sectors have continued to grow as AI tools are benefiting veteran workers — those who have gained knowledge from experience.

The $46 billion in data centers proposed or under construction in Wisconsin continue to make news over who should pay for the electricity to power them, whether municipalities should use nondisclosure agreements to keep details confidential and more. Here are some of the latest updates:

Utility rates: The state Public Service Commission is accepting public comment on a We Energies proposal for determining whether the general public pays any share of the costs of constructing and operating power plants needed to meet data centers’ electricity demands. One concern is creating more “stranded assets” — power plants that are shut down before their debt is paid off. Wisconsin Watch reported in December that Wisconsin ratepayers owe $1 billion for stranded assets.

Legislation: A state Senate committee is holding hearings Tuesday, Feb. 17, on three data center bills. Senate Bill 729 seeks to limit how much general ratepayers can be charged by utilities for the cost of providing electricity to data centers. Senate Bill 843 contains a similar provision and has passed the Assembly, but also contains a controversial requirement that renewable energy used for a data center be on the data center site. Senate Bill 969 would prohibit local governments from signing nondisclosure agreements with data center developers. Separately, a new bill would impose 14 requirements on data center proposals, including prohibiting NDAs between local governments and data center developers. Wisconsin Watch found that local officials in at least four communities signed NDAs to hide details of data center proposals. 

Janesville: The City Council put on the Nov. 3 ballot a referendum proposed by data center opponents that could give voters direct say over a hyperscale data center. If the referendum is approved, it would create an ordinance requiring separate referendum approval for any type of development project worth $450 million or more that is proposed for the former General Motors site. The data center proposed for Janesville is worth $8 billion.

Port Washington: Business groups are suing to block a proposed ordinance affecting economic development projects. The proposal was made by citizens who claimed a lack of transparency by the city over a $15 billion data center now under construction. 

Grant County: A company seeking a site for a $1 billion data center has included rural Cassville in southwest Wisconsin in its search. A local official said he expects to learn in spring whether the county is still being considered.
