PSC Approves Fox Solar Project

PSC Approves Fox Solar Project

by | May 21, 2026 | Public Service Commission, RENEW Wisconsin, Solar, Utility Scale

On Thursday, May 21, the Public Service Commission of Wisconsin (PSC) approved the Fox Solar Project. At 100 Megawatts (MW), this solar project will produce enough clean energy to power about 25,000 homes. The project is paired with a 50 MW battery energy storage system, providing the flexibility to provide power when the sun goes down.

Located in Oconto County, it is planned for completion in 2028. Projects like this have a wide range of local and statewide benefits, including economic growth, new funding for local municipalities, and reduced emissions from energy production.

Witness testimony from David Loomis of Strategic Economic Research stated that this project will create 300 temporary jobs during construction, along with an additional 20 long-term jobs related to the project’s economic activity.

Along with jobs, the project will support the surrounding communities through utility-aid payments. Over the 25-year life of the project, it is expected to contribute more than $13 million in utility aid payments to Oconto County and the Town of Morgan. Recent legislation has changed utility-aid payments to also include battery installations, which has increased the previous estimate on payments for local governments.

Beyond the economic aspects of this project, it also provides an additional source of clean, reliable energy that isn’t subject to volatile fuel prices. With this project we’re removing 304 million pounds of CO2 related to energy production in the first year of operations, and that’s just the CO2 emissions.

The amount of emissions reductions we’ll see from the project is about the same as taking almost 30,000 cars off the road. Avoided emissions, whether from energy production or our cars, means healthier air for everyone. We estimate that in Fox Solar’s first year of energy production, we’ll see $690,000 in economic benefits associated with the public health improvements we expect to see

Thanks to everyone who took the time to share their support of Fox Solar with the PSC!

Planting Solar Where It Matters Most

Meet RENEW Wisconsin’s Spring 2026 Solar for Good Awardees

Casa Ester has been in Omro for nearly twenty years. They welcome migrant farmworker families arriving in Winnebago County, run a youth garden that donates produce to local food pantries, teach social justice education to participants in over a dozen countries, and last year alone helped more than 450 people stay housed. Every dollar they have goes toward the people who walk through their door.

When Casa Ester decided to go solar, the reasoning was clear. Spending less on electricity means more money available for families facing eviction. They, along with five other organizations, have been selected as awardees of this spring’s Solar for Good grant round. Each organization will receive a $5,000 grant to support its efforts to reduce its energy burden and carbon footprint. By going solar, they can do more to serve communities across the state.

The Spring 2026 Awardees

In Chippewa Falls, Hope Village is the only no-cost emergency shelter in Chippewa County. Since 2016, they have helped 339 people navigate housing instability, with 71% finding permanent housing on the other side. This is their second solar project, built on the success of the first. Lower energy costs mean more capacity to serve guests, run programming, and keep the doors open for people who have nowhere else to go.

In Tomah, First Congregational UCC has been working toward solar for three years. Located in Monroe County’s highest-poverty city, they run an early childhood center, support foster families, and provide meals at the free clinic. This summer, they will become the first church in Tomah to go solar and are already planning an open house where they will invite every congregation in town and ask the question they have been sitting with.

TransCenter for Youth has been running small alternative high schools in Milwaukee since 1973, serving students who have not found their footing in larger, more traditional systems. At Shalom High School, students will soon track real-time energy production from a restored solar array through a live dashboard they helped design. The energy savings go back into the school. Beyond the financial benefit, there is something meaningful about a school where students have often been told resources like this are not available to them choosing to lead on clean energy.

At Lake Mills Area School District, solar is going up across the Elementary and Middle Schools. The district also runs a senior center partnership, a multilingual learner program for immigrant families, and a student-run food pantry called The Mills. The energy savings from a project of this size are real and recurring, freeing up resources year after year to keep those programs funded and those buildings open to the full community.

In Strum, the local public library is building a timber-framed solar canopy that also serves as an outdoor learning and programming space. The savings on utilities go directly back into programming for the community. This summer, children in the reading program will learn about solar energy through hands-on activities and watch live energy production on a display inside the library. It is a thoughtful investment from a community that takes its role as a public resource seriously.

The Same Logic, Six Times Over

Six organizations. Six communities. Different missions, different zip codes, different sizes. The same logic runs through all of them: when organizations spend less on keeping the lights on, they have more to give to the people who need them most. We are proud to support each of these groups and look forward to celebrating with them at their ribbon cuttings.

Help Us Do More of This

Every organization in this cohort is doing more for their community because solar has freed up room in their budget. Solar for Good runs on the support of donors who believe clean energy should reach every corner of Wisconsin, not just the places that can easily afford it. A gift goes directly toward grants for nonprofits, schools, libraries, shelters, and faith communities doing work that matters.

Every $5,000 raised is one more organization that gets to do a little more for its community. It’s that simple.

If this work resonates with you, please consider making a gift today. Help us continue to plant solar where it matters most.

PSC Approves Muddy Creek Solar Project

PSC Approves Muddy Creek Solar Project

by | May 14, 2026 | Public Service Commission, RENEW Wisconsin, Solar, Utility Scale

On Thursday, May 14, the Public Service Commission of Wisconsin approved Muddy Creek Solar, a 322 Megawatt (MW) solar project paired with a 300 MW battery energy storage system. Developed by Geronimo Power, the project is expected to provide nearly $2 million in annual utility aid payments to local municipalities.

Geronimo Power has also shown its commitment to supporting the community that will host the project by pledging an annual $75,000 donation to local school districts. Through a Charitable Pledge Agreement, the Menomonie Area School District and the Elk Mound Area School District will receive $12,500 and $62,500, respectively, for 20 years after the project begins operations.

In addition to the direct cash benefit to local municipalities, the project is expected to create more than 800 temporary jobs during construction and more than 50 long-term jobs. Also important to consider is the direct payments to landowners who have leased their land for the life of this project.

This project shows that clean energy projects can bolster our local economies, provide our state with the energy it needs, and reduce our carbon emissions from energy generation.

In total, we expect this project to reduce emissions by 954 million pounds of CO2, the equivalent of removing 94,000 gas-powered vehicles from our roads. And that’s just the CO2.

Thanks to the reduction of CO2 and the several other greenhouse gases that fossil fuels would pump into the air we breathe, Wisconsin can expect more than $2 million in economic benefits associated with public health improvements in Muddy Creek Solar’s first year of operations alone.

This solar and battery project will provide many things Wisconsin needs—jobs, reliable energy, consistent income for landowners, more funding for our schools and local governments, and cleaner air. And when the project reaches the end of its life, the land can be returned to its prior use, whether that be agricultural, recreational, or some other purpose.

Thanks to everyone who took the time to share their support for this much-needed energy project. Together, we can transform how Wisconsin is powered.

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.

Akron Solar Approved!

Akron Solar Approved!

by | Mar 6, 2026 | Action Alert, Advocacy, Renewables, Solar

Earlier this week, the Public Service Commission of Wisconsin (PSC) approved Akron Solar! This 200 Megawatt (MW) solar project will be located in Adams and Wood Counties and is planned for completion in the latter half of 2029. Projects like this have a wide range of local and statewide benefits. Thanks to everyone who helped make this project happen, especially those who submitted comments to the PSC and told them why Wisconsin needs more solar power!

Even though we’re only three months into 2026, we are excited about the amount of progress we have already made. That said, there’s plenty more for us to accomplish this year. We hope you’re just as excited as we are to keep the momentum up and help us create a future where everyone benefits from the renewable energy revolution!

Akron Solar’s benefits extend well beyond the clean energy it will produce. If you’re not familiar with the project, below are some additional reasons why we support this project:

 

  • Economic Growth: According to a report by Strategic Economic Research, Akron Solar will create more than 450 jobs during construction, as well as more than 14 good-paying, long-term positions in Adams and Wood Counties.
  • Community Benefits: Once in service, Akron Solar will contribute more than $1,000,000 in utility-aid payments each year. Over $566,000 of this will go to the counties, while the remaining $433,33 will go to the towns of Rome and Saratoga. During its 25-year life, the project will contribute a total of at least $25million in utility-aid payments.
  • Emissions Reductions: Akron Solar will reduce energy production emissions by 650 million pounds of CO2 in the first year of operations. In terms of greenhouse gas emissions, this is the equivalent of taking more than 64,000 vehicles off the road for a full year. These emissions reductions will result in health, economic, and environmental benefits. Wisconsin can expect more than $1.4 million in economic benefits associated with public health improvements in Akron Solar’s first year of operations alone.
