PSC Critizes, Modifies, and Approves Alliant Energy Data Center Contract

PSC Critizes, Modifies, and Approves Alliant Energy Data Center Contract

by | May 7, 2026 | Advocacy, Community, Public Service Commission, RENEW Wisconsin

On Thursday, May 7, the Public Service Commission of Wisconsin (PSC) approved Alliant Energy’s contract with Meta regarding their data center in Beaver Dam, but not before criticizing their lack of transparency and significantly modifying the contract. Modifications included safeguards requiring the utility to cover transmission costs and to address the potential for underpayments from the data center.

The PSC was clear today in its decision regarding Alliant Energy’s contract with Meta—Wisconsin utilities must be more transparent about their relationships with data centers and ensure that not a single cent of the costs of powering data centers is passed on to Wisconsin families and small businesses.

“I want it to be clear that whether you’re a large load customer coming in to Wisconsin for the first time or a regulated entity familiar with our process, transparency, and by that I mean actual and real transparency, is a foundational expectation and a necessity,” Commissioner Summer Strand said. “Frankly, transparency is quite often mutually beneficial, and I don’t think it needs to be this difficult, so I was a little disappointed, and initially, it was like pulling teeth here to increase the transparency.”

We are encouraged by the PSC signaling that they want utilities not only to place greater emphasis on transparency, but also to have a Very Large Customer tariff that is the same for each data center in their territory. This makes it easier to ensure that each data center pays the same and that all of them pay their own way in Wisconsin.

Though we would have preferred a rejection of this contract today, there was a clear win. As it should be, the PSC is ensuring it is easy for us to verify that data centers are paying for their own energy and infrastructure.

We also encouraged the PSC to be proactive in urging data centers to invest in clean energy technology, especially emerging or cutting-edge technologies. These new neighbors have the resources to spur growth in the world of renewables, and if they intend to be responsible neighbors, they will help us expand our renewable energy footprint rather than stall our progress in combating climate change.

No More Kings: Let’s Build the Future While the Administration is Distracted

No More Kings: Let’s Build the Future While the Administration is Distracted

We’ve seen this history play out before.

Just as momentum for clean energy gains ground—projects rising, costs falling—a new decree arrives from above. The return of top-down, centralized energy policy isn’t just a debate; it’s an attempt to rule by rollback. It’s the old guard trying to reclaim power by stalling investment and clouding the future with uncertainty.

But here’s the thing about progress: it doesn’t belong to any single person. It belongs to the people building it on the ground, right here in Wisconsin.

The Decree vs. The Reality

When leadership tries to reign over the energy transition, we, the people, pay the price:

  • Infrastructure is halted by royal red tape.
  • Investment is chased away to more stable lands.
  • Communities lose their independence to volatile, old-world costs.

We aren’t waiting for a coronation or a change of heart in a distant capital. At RENEW Wisconsin, we believe in a self-governing energy future. We move forward because the climate doesn’t care who sits in the Oval Office.

A Revolutionary Act for Your Individual Retirement Account (IRA)

You don’t have to be a spectator in this power struggle. If you are 70½ or older, you have a unique tool to help fund resistance to progress-killing policies: the Qualified Charitable Distribution (QCD).

Think of it as a way that you can defund an agenda you don’t support and put those funds directly into the hands of those building the future.

With a QCD, you can:

  • Move IRA funds to RENEW Wisconsin to protect local projects.
  • Avoid increasing your taxable income.
  • Satisfy your Required Minimum Distribution (RMD) on your own terms.
  • Ensure your legacy builds local power, not political theater.

Let’s Democratize Energy

You’ve spent a lifetime building your own estate. You know that true stability isn’t granted by a leader—it’s built through hard work and foresight.

The window to act is open, but the gates can be slammed shut by the next administration. Don’t let your hard-earned resources be eroded by shifting political winds. Use a QCD to reinforce the progress we’ve made.

Wisconsin doesn’t answer to kings. We answer to the future we build.

Utilities Ramping Up Solar Power Build-Out

Utilities Ramping Up Solar Power Build-Out

by | Apr 29, 2026 | RENEW Wisconsin, Renewables, Solar, Utility Scale

But their anticipated output would not be sufficient to serve data center projects in the construction pipeline

*Guest Blog by Michael Vickerman—RENEW Wisconsin Board Member

Construction of large solar power plants in Wisconsin will accelerate throughout the decade, thanks to a series of regulatory approvals handed down over the past 12 months. Indeed, by all appearances, solar power will dominate utility investment in new sources of electric power for the foreseeable future.

In March 2026 alone, the Public Service Commission of Wisconsin (PSC) approved utility requests to acquire three solar projects—two in Columbia County and one in Rock County—totaling 315 megawatts (MW). When energized over the next two years, these three plants will generate more than 600,000 megawatt-hours of zero-emission electricity annually to customers. That amounts to 0.9% of electricity consumption in the Badger State. 

As shown in Table 1 below, WEC Energy and Madison Gas & Electric will add 1.265 gigawatts, or 1,265 MW, of solar power to their generation fleets over the next three years. Construction is well underway at the Koshkonong and High Noon project sites, and ground will be broken this year on the other solar plants listed in the table.

Construction is also proceeding on a 250 MW solar plant in central Wisconsin owned by Minneapolis-based Geronimo Energy. Anticipated to be placed in service later this year, the Portage Solar plant will produce electricity for the wholesale market and sell the renewable energy credits (RECs) from that generation to Microsoft, which will soon complete construction on a hyperscale data center in Racine County. When activated later this year, Microsoft’s facility will become the largest consumer of electricity in the entire state, with a baseline demand of approximately 500 MW. Microsoft will purchase all of the RECs produced by Portage Solar to offset a portion of that facility’s electricity usage. 

Utility-owned solar generating plants often come paired with battery energy storage systems (BESS) placed within the project boundaries. These installations can store up to four hours of electricity at the battery’s rated capacity. 

At the Koshkonong project, for example, the battery system is designed to accept as much as 660 MWh of electricity generated onsite. These BESS units will enable grid operators to discharge stored electricity directly into the transmission system when demand peaks later in the afternoon and evening. 

In just a handful of years, solar has emerged as the fastest-growing in-state source of electric power, and its contribution to electricity supplies now surpasses wind and hydro combined (see Table 2). Accounting for 6.6% of Wisconsin-generated electricity in 2025, solar generation could reach the 10% threshold by 2030.

Will solar growth be large enough to offset anticipated load growth driven by hyperscale data centers? 

As impressive as solar’s growth was in 2025, it wasn’t large enough to fully offset the increase in electricity consumption that occurred that year. The other generation resource that saw a significant increase in output from 2024 was coal, whose rise came at the expense of fossil methane. Factoring in other hyperscale data centers now under construction, it will be a challenge to offset rising electricity sales with new solar generation.

As applied to retail electricity customers, the term “capacity factor” is a measure of their actual electrical consumption in a year divided by its peak demand multiplied by 8,760, the number of hours in a year. The consensus estimate of a hyperscale data center’s capacity factor falls in the 75% to 80% range. 

Compared with other customer types, hyperscale data centers impose an unprecedented level of demand on the electric grids that serve them, due to the following reasons.

  • Massive scale of operations serving millions of users; 
  • Expansion of AI use is driving the need for high-density computing power;
  • Energy-intensive cooling systems; and
  • Always-on operations requiring uninterruptible electrical service.

With the above in mind, let’s estimate the power consumption from Microsoft’s Mt. Pleasant campus that will commence operations later this year. If we assume a peak load of 500 MW and a capacity factor of 75 to 80%, electricity consumption from this particular entity would range from 3.3 to 3.5 million MWh per year, or 5% of the electricity sales recorded in the entire state of Wisconsin last year. 

It would take six solar plants the size of Koshkonong–1,800 MW in total–to offset, on a MWh by MWh basis, the anticipated consumption from just the Mt. Pleasant data center alone. When the two Beaver Dam and the Port Washington data center projects are brought into the picture, the number of Koshkonong-size projects needed to offset all four hyperscalers in the pipeline would exceed 20. 

Given that, it’s fair to conclude that the data center build-out will elevate greenhouse gas emissions from Wisconsin’s electric power industry even with a robust expansion of in-state solar power. Unless something changes on the ground, this worrisome outcome, and all the unpleasant environmental and economic consequences that it will amplify, is quite literally baked into our future.

About That Hail and Your Solar Panels

About That Hail and Your Solar Panels

by | Apr 29, 2026 | Community, RENEW Wisconsin, Solar

April has been a rough month for much of Wisconsin. Hail, high winds, tornadoes, and heavy rain have rolled through the state, causing real damage. Here in Madison, the storm on April 14 brought baseball-sized hail, almost three inches across!

Other parts of central and southern Wisconsin got even bigger stones. Cars were dented. Roofs were torn up. Siding was cracked. Power poles came down. And yes, some solar panels broke too.

That’s the reality of weather like this. Extreme storms damage what’s in their path, and almost nothing on the outside of a home gets a free pass when hail comes down at that size. If your panels took a hit, they may need to be repaired or replaced. That’s not great news, but it’s also not the end of the world.

If you were thinking about going solar before the storms rolled through, the storms shouldn’t change the math on that decision. The path forward, whether you’re repairing a system or building one for the first time, looks a lot like dealing with any other part of your home.

How to Get Your System Back Up and Running

When panels get damaged in a storm like this, the fix looks a lot like dealing with hail damage to your roof or siding. The process moves through a few clear steps.

Contact Your Homeowner’s Insurance and Your Installer

Both should know what happened as soon as possible. Your installer works directly with the insurance company on your behalf from there. They document the damage, walk the adjuster through what they’re seeing, and handle the repair, replacement, and reinstall. The homeowner isn’t navigating it alone.

Know Your Coverage Before a Storm Hits

Most standard homeowner’s policies cover rooftop solar under the dwelling section, but it’s worth confirming that hail and wind are listed as covered perils and that your coverage limit reflects what your system is actually worth. Some policies in hail-prone areas carry separate wind and hail deductibles, and ground-mounted systems sometimes need a separate rider, so it helps to know what your specific policy says before you need to use it.

The Rest of the System Is Built To Make This Manageable

Manufacturers test their panels to real standards. Installers know how to work with insurance companies. Each part does its job so that when something does go wrong, the path forward is clear.

Your installer can also help you sort out what’s covered by equipment warranties versus insurance, and show you how to use your monitoring app to confirm the system is performing normally after repairs.

What Hail Does to a Panel

Knowing what kind of damage you’re looking at helps you follow along when your installer comes out for an inspection.

  • Visible damage is less common than people expect, but also the most obvious when it happens. Cracks, chips, or spiderwebbed glass that you can spot from the ground. The tempered glass on top of a panel is built to take a hit, which is why this kind of damage usually only shows up in the more extreme storms. Worth noting too: when a panel does break, the glass stays contained inside the panel. Solar panels are sealed between layers of plastic and held together by an aluminum frame, so cracks don’t send glass flying across your yard or your neighbor’s.
  • Hidden microcracks are the ones experts worry about more. These are microscopic fractures inside the solar cells that might not affect performance right away, but can spread over time the same way a small chip in a windshield can grow into a longer crack. Left unchecked, microcracks can gradually reduce efficiency and create hot spots inside the panel. That’s why post-storm inspections matter even when a system seems to be running fine. 
  • Cell and busbar damage happens beneath the surface when hail’s impact energy transfers through the glass. The busbars are the thin metal strips that carry electricity across the panel. Modern panels use many ultra-thin busbars or wires per cell, often well into double digits, which helps keep current flowing even if part of a cell takes a hit.

A cracked panel will usually still generate electricity at reduced output. If it needs to be replaced, it should be replaced. If it’s still performing within spec, it can keep running. The key is having someone qualified take a look so you know what you’re working with.

A Quick Note on the Testing

Quality solar panels are built to two main standards that work together.

  • IEC 61215 is the performance and durability standard set by the International Electrotechnical Commission. It covers how a panel holds up against weather, including the hail impact testing, where technicians fire ice balls at panels using compressed air cannons. The basic test uses one-inch ice balls at high speeds, and many panels are tested even further against ice balls up to three inches across at speeds up to 88 miles per hour. To pass, the panel has to keep producing power within spec after the impact.
  • UL 61730 is the safety standard set by Underwriters Laboratories, which covers electrical safety, fire resistance, and structural integrity. Together, they tell you a panel can take the weather and stay safe doing it.

The Bigger Picture

Everything on the outside of your home already takes a beating from Wisconsin weather. Your roof, your siding, your windows, and the AC unit out back. None of that has stopped anyone from owning a home. You carry insurance for a reason, and when something breaks, you call somebody who knows how to fix it. Solar panels are no different than anything else on your house in that respect.

April has been hard on Wisconsin, no question about it. But the things people depend on after a storm have shown up. Insurance is paying out. Installers are out doing the work. Hail and wind can damage panels. That’s true. What matters is having the right people in your corner and the right coverage in place when it happens. A solid installer and the right insurance policy take care of that.

PSC’s Preliminary Decision: Data Centers Will Cover Their Costs

PSC’s Preliminary Decision: Data Centers Will Cover Their Costs

by | Apr 27, 2026 | Advocacy, Policy, Public Service Commission, RENEW Wisconsin, Renewables

Last Friday, April 24, the Public Service Commission of Wisconsin (PSC) unanimously approved an electricity rate plan for data centers and other “Very Large Customers” (VLC) in We Energies’ service territory. This decision will protect Wisconsinites from shouldering the financial burden of the energy and infrastructure costs associated with data centers.

RENEW Wisconsin submitted comments in support of this decision to protect Wisconsin ratepayers. We also asked the PSC to include considerations such as energy efficiency and renewable energy in their decision-making process. Meaning these corporations with massive financial means should, at the very least, be investing in building and operational efficiency, while also signing contracts with utility-scale solar projects.

We also highlighted the importance of these large corporations sticking to their own sustainability goals and how, through their vast access to capital, they could incorporate emerging or cutting-edge renewable energy resources to mitigate their contributions to climate change.

As our Policy Director, Andrew Kell, said in his comments to the PSC, “Data centers have adequate resources to become key innovators and provide the ‘technology push’ and ‘demand pull’ required for these programs, technologies, and infrastructure to scale up and flourish.”

While we don’t have guarantees that data centers will lead the charge on innovation as it relates to renewables, we do at least have a strong indication that the PSC will continue to protect ratepayers in future proceedings related to data centers.

“The decisions we’re making here today will not be limited to this docket,” said PSC Commissioner Kristy Nieto. “They will shape future proceedings, future investments, and the trajectory of the utility system itself.”

The PSC also determined that the energy demand threshold for a VLC to qualify for this rate structure should be reduced from 500 megawatts (MW) to 100 MW, the level at which new energy generation projects typically require PSC approval. The PSC also made it mandatory for eligible VLCs to subscribe.

VLCs will also need to fund and subscribe to portions of multiple new power generation projects, or entire projects, as they will be the driver of much of the state’s new energy demand.

We are still waiting for the final written order for this decision, but we are glad that PSC’s preliminary decisions align with what many public comments submitted stated, which is that data centers must pay the full costs of the energy and infrastructure they require.

As data center development progresses, RENEW aims to collaborate with data centers and strongly encourage them to drive and fully pay for cutting-edge clean energy resources. If data centers do in fact strive to incorporate into communities, they should help to ensure that we can create a sustainable, zero-carbon future.

Our shared home and all of its inhabitants deserve protection. It’s been said many times before, but it deserves repeating—we only have the one Earth.

For the last 35 years, supporters like you have helped us lead the charge as we fight to create a future powered by renewable energy. In that time, we’ve made a lot of progress and continue to expand our efforts to end our reliance on fossil fuels and combat climate change.

In 2025 our efforts to support renewables resulted in:

  • 5.6 million megawatt hours of renewable energy generated
  • 9 billion pounds of carbon emissions avoided
  • 560,000 homes powered by renewable energy

We also helped 25 nonprofit organizations go solar through our Solar for Good grant program. This year, we’re looking to do even more to bring the benefits of renewable energy to every corner of Wisconsin.

In 2026 we have already:

  • Supported two utility-scale solar projects
  • Supported one utility-scale wind project
  • Highlighted the value of clean energy jobs
  • Advocated for data center legislation that protects Wisconsinites
  • And Hosted our Annual Summit!

We’ve also seen three new utility-scale renewable projects get approved by the Public Service Commission of Wisconsin! Each of these wins brings us one step closer to our goal of creating a healthy climate and an economy we can afford. And there’s so much more we hope to achieve. It is, after all, still spring. By winter, we hope our list of achievements has gotten much longer. Together, we can make it happen!
