Wisconsin Just Approved a Landmark Power Deal for Meta's $1 Billion Data Center — But Regulators Want the Rules to Change
On May 7, 2026, the Wisconsin Public Service Commission voted to approve a modified electricity contract between Alliant Energy and Meta, clearing the path for a 220-megawatt data center campus in Beaver Dam, Wisconsin. The project, worth roughly $1 billion and spanning 700,000 square feet, represents one of the largest single infrastructure commitments Meta has made in the Midwest — and one of the most contentious utility deals Wisconsin regulators have had to weigh in years.
The approval itself was not the headline. The condition attached to it was. Wisconsin Watch reported that commissioners criticized Alliant's negotiation approach as a "black box" — a secretive, one-off process that gave the public and other ratepayers no visibility into how the deal was structured. In the same breath that they approved the Meta contract, the PSC ordered Alliant to develop a standardized, public rate structure for all future large data center customers before any additional hyperscale facility comes online in its territory. The message was clear: this is the last deal of its kind.
What Alliant Energy and Meta Actually Agreed To
The approved contract commits Alliant Energy's subsidiary Wisconsin Power and Light to supply power for Meta's Beaver Dam campus under a minimum 10-year agreement, with two optional five-year extensions that could stretch the arrangement to 20 years. The facility is expected to come online in 2027, and its peak energy demand — 220 megawatts — would be six to eight times the current peak electricity load for all of Beaver Dam combined.
That number deserves a moment of context. Beaver Dam is a city of roughly 16,000 people. A single corporate data center drawing more power than every home, business, and industrial facility in that city put together is not a marginal addition to the grid — it is a structural transformation of local energy infrastructure. That's the scale at which hyperscale computing now operates.
Meta has been direct about the economics. A company spokesperson stated that Meta covers the full energy cost, meaning existing residential and commercial ratepayers won't see their bills increase to subsidize the facility. The company also says the project includes nearly $200 million in energy infrastructure investments and is projected to generate $2.1 million in annual tax revenue across local, state, and federal levels. WUWM's reporting noted that public skepticism about these assurances ran high during the approval process, with community members expressing concern that the confidential nature of the deal made those claims difficult to verify independently.
The 'Black Box' Problem: Why Regulators Pushed Back on the Process
Wisconsin Power and Light, the Alliant subsidiary handling this deal, filed its case with the PSC in spring 2025 — months before Meta even officially announced the Beaver Dam campus. That sequencing alone raised eyebrows. The contract was negotiated confidentially, without the kind of public rate-setting process that governs how utilities typically price service for large industrial customers.
Commissioners did not hide their discomfort. According to Wisconsin Watch, the PSC used explicit language about the lack of transparency and consistency in Alliant's approach. The concern is structural: when a utility negotiates bespoke contracts behind closed doors with individual corporations, there is no public framework for assessing whether the deal is fair to existing ratepayers, fair to potential competitors for the same service, or consistent with how the utility will handle the next company that comes knocking.
And there will be more companies knocking. Alliant has confirmed it is in active discussions with roughly a dozen additional data center projects across its service territory, spanning the Dane County suburbs, southwest Wisconsin, and much of Iowa. Without a standardized public tariff, each of those deals would face the same opacity problem — a situation the PSC is clearly determined to prevent.
Channel 3000 reported that the PSC's order requires Alliant to establish a standardized public rate structure covering any data center customer seeking at least 100 megawatts of capacity before another such facility is approved for service. That threshold is not arbitrary — 100 megawatts is roughly the lower bound for what the industry considers a hyperscale facility. By setting the bar there, the PSC is targeting the category of customer that poses the greatest structural risk to grid planning and ratepayer equity.
Alliant's Unusual Grid Position: No New Power Plants (Yet)
One of the more technically significant details in this story is what Alliant says it will not do, at least immediately. Unlike We Energies — which has proposed building new generation capacity to serve its own large data center customers — Alliant says it does not currently expect to construct new power plants to meet the Beaver Dam campus's load.
That's a meaningful distinction. New generation construction means significant capital expenditure, and under traditional rate-of-return utility regulation, those costs can eventually flow back to ratepayers through rate cases. If Alliant can serve Meta's 220-megawatt load through existing or contracted generation capacity, the direct financial exposure for ordinary customers is more limited — at least in the near term.
The caveat is that Alliant's pipeline of roughly a dozen additional data center projects changes that calculus substantially. Twelve more large facilities, each potentially drawing 100 megawatts or more, would require significant new generation and transmission infrastructure. The question of who pays for that buildout — and how costs are allocated between data center operators and existing customers — is precisely why the standardized tariff the PSC ordered matters so much.
Wisconsin is not alone in wrestling with this. Utilities across the country are facing the same pressure as artificial intelligence infrastructure, cloud computing, and cryptocurrency operations drive electricity demand to levels that were genuinely unforeseeable a decade ago. The regulatory frameworks most states have were built for a world where industrial load grew gradually and predictably. Hyperscale data centers don't behave that way.
The Broader Wisconsin Landscape: We Energies, Alliant, and the Coalition
Wisconsin's experience with data center electricity regulation is developing quickly. In April 2026, the PSC approved a heavily modified We Energies proposal for a standard electric rate structure covering large data centers in its service territory — a move that set a regional precedent and likely accelerated the PSC's decision to impose similar requirements on Alliant.
Alliant is also a founding member of the Wisconsin Data Center Coalition, a lobbying and industry group formed to facilitate data center investment in the state. That membership positions Alliant as a proactive player in attracting hyperscale customers — which makes the PSC's transparency requirements all the more important as a counterweight. When a utility is actively recruiting the largest possible electricity customers while also responsible for setting rates that affect existing customers, independent regulatory oversight becomes essential.
Reports from the PSC's decision indicate the commission wants the new tariff framework finalized before any subsequent data center application advances — a hard sequencing requirement that gives the order real teeth. Alliant cannot simply proceed with its pipeline of pending projects while the tariff development drags on indefinitely.
What This Means: The Utilities-AI Infrastructure Reckoning
The Alliant-Meta deal is a microcosm of a national tension that will define energy policy for the next decade. The economic case for large data centers is real: tax revenue, infrastructure investment, high-wage construction jobs, and a regional economic anchor. The Beaver Dam project's $2.1 million in projected annual tax revenue is meaningful for a smaller Wisconsin community, and the $200 million in energy infrastructure investment modernizes grid assets that benefit everyone in the service territory.
But the risks to existing ratepayers are equally real. When utilities build out massive infrastructure to serve a single corporate customer, and that customer later decommissions or relocates the facility, the stranded costs don't evaporate — they get allocated across the remaining customer base. The 10-year minimum contract term on the Meta deal provides some protection, but 10 years in the technology industry is a long time, and a lot can change in the business case for any specific data center location.
The PSC's decision to approve the Meta deal while simultaneously condemning the process that produced it strikes the right balance for the moment. Wisconsin needed to approve or reject a specific application; it approved it, and the economic rationale is defensible. But regulators correctly identified that the precedent being set — bespoke, confidential contracts for the largest electricity customers in the territory — was incompatible with the transparency obligations utilities carry as regulated monopolies.
The standardized tariff requirement is the right structural response. Public rate structures allow ratepayer advocates, competing businesses, and community members to evaluate whether large data center customers are paying their full share of infrastructure costs. They create consistency and predictability for utilities and potential customers alike. And they give future PSC decisions about data center applications a factual foundation that confidential negotiations cannot provide.
The deeper question — whether AI and cloud infrastructure companies should be treated more like traditional industrial customers or as a categorically different class requiring new regulatory frameworks — remains open. Wisconsin is working through it faster than most states. The answers it develops will likely influence how other public utility commissions approach the same problems.
FAQ: Alliant Energy, Meta, and Wisconsin's Data Center Rules
Will existing Wisconsin ratepayers pay more because of the Meta data center?
Based on current information, the direct answer is no — at least for the Beaver Dam campus. Meta's spokesperson stated that the company covers the full energy cost, and Alliant says it does not plan to immediately build new power plants to serve the facility. That said, infrastructure investments tied to serving the campus may eventually factor into rate cases, and the cumulative effect of Alliant's full pipeline of data center projects could create upward pressure on rates over time. The standardized tariff the PSC ordered is designed in part to ensure those costs are properly allocated.
Why did the PSC criticize the deal it just approved?
Regulatory bodies frequently approve transactions while expressing reservations about the process or conditions surrounding them — particularly when rejecting a specific application would harm a project already in development while setting a broader policy through separate regulatory action is more appropriate. The PSC approved the Meta-specific contract because it met the legal and economic standards required; it criticized the negotiation approach and ordered a new framework because that approach should not continue for future deals. The two actions are complementary, not contradictory.
What is the significance of the 100-megawatt threshold in the new tariff requirement?
A 100-megawatt demand threshold captures the category of customer that places the greatest strain on grid infrastructure and raises the most significant questions about cost allocation. Smaller industrial customers — manufacturing facilities, commercial campuses, hospitals — typically fall well below that level and can be served under existing industrial rate schedules. Hyperscale data centers routinely exceed it. By targeting the new standardized tariff at the 100-megawatt threshold, the PSC is addressing the specific category of customer that has created the transparency and equity problems it's trying to solve.
How does the Meta Beaver Dam project compare to other data center developments in Wisconsin?
The Beaver Dam campus — 220 megawatts, 700,000 square feet, approximately $1 billion in investment — is large by any measure. Alliant's pipeline of roughly a dozen additional projects suggests Wisconsin is becoming a significant data center destination, likely driven by land availability, utility infrastructure, favorable regulatory environment, and access to renewable energy resources. The We Energies territory in southeastern Wisconsin, which includes Milwaukee, is seeing similar pressure, as evidenced by the PSC's April 2026 approval of a standard rate structure for large data centers in that service area.
When will the Meta Beaver Dam data center open, and what happens if the timeline slips?
The facility is currently projected to come online in 2027. The contract's 10-year minimum term and structured extension options suggest Meta is committed to a long-term operational presence in Beaver Dam, not a speculative development. If the timeline slips due to construction delays, supply chain issues, or other factors, the contract terms would govern how energy delivery obligations are handled. The PSC's review of modified contract terms suggests regulators scrutinized exactly these contingencies before approving the deal.
Conclusion: A Turning Point in How Utilities Handle Hyperscale Customers
The Wisconsin PSC's May 7, 2026 decision will be studied by utility regulators in other states for years. It demonstrates that it is possible to approve a specific large-scale energy contract while simultaneously reforming the process that produced it — and that doing so sends a cleaner signal to industry, ratepayers, and future applicants than either a blanket rejection or an unconditional approval would have.
Meta gets its data center. Alliant gets a major long-term customer. Beaver Dam gets tax revenue and infrastructure investment. And Wisconsin ratepayers get the regulatory safeguard that existing customers were owed from the beginning: a public, standardized framework that treats all large data center applicants consistently and transparently.
What happens next in Wisconsin — how quickly Alliant develops the new tariff, how the PSC responds to the next application in Alliant's pipeline, and whether the state's approach influences federal thinking about data center electricity regulation — will determine whether this decision was a turning point or just a well-handled one-off. Given the scale of investment flowing into AI infrastructure and the pace at which utilities are being asked to adapt, the stakes of getting the regulatory framework right have rarely been higher.
