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!

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.

Bent Tree North Wind Project Approved

Bent Tree North Wind Project Approved

by | Apr 21, 2026 | Renewables, Utilities, Utility Scale, Wind

On April 21, Alliant Energy announced the unanimous approval of the Bent Tree North Wind project. The 153-megawatt (MW) wind project will include 32 wind turbines and expand on the existing Bent Tree Wind Farm, which has been operating successfully since 2011. Since the project is located in Minnesota but will send power to Wisconsin, it required approval in both states.

Upon completion, the Bent Tree North Wind project is expected to generate enough electricity to power about 50,000 homes each year. This expansion of Alliant’s renewable energy portfolio is a win for Wisconsin residents in terms of both energy affordability and grid reliability.

More renewable energy means less reliance on fossil fuels, which at times experience volatile pricing, and diversifies our energy resources. This helps keep energy prices from rising and gives us more options for keeping the lights on.

And while this project will reduce the carbon footprint of our state’s electricity production, it will also be economically beneficial to the region where it is hosted. It is expected that the local area will see $100 million in local economic benefits over the project’s 30‑year (or so) life. Some of these benefits will come in the form of tax revenue, landowner payments, and wages for the 100-150 construction jobs the project will support.

The turbines used for the project will also support the economies in the Midwest. Alliant Plans to use Nordex N133s, a 4.8 MW turbine, which has several key components constructed at Nordex’s Iowa facility.

The turbines are also designed to produce more energy per tower, resulting in less disturbance to the land hosting the project. Standing at an impressively tall 606 feet, the towers are able to support larger rotors, which in turn increases energy production and efficiency. This means more energy at a lower cost.

We’re glad we were able to show our support for a project that fights climate change, boosts local economies, and helps keep Wisconsin’s utility bills more stable.

Energy Storage Utility Aid Law Passes

Energy Storage Utility Aid Law Passes

by | Apr 16, 2026 | Local Government, Utility Scale

On April 3, 2026, Governor Tony Evers signed a bill that allows counties and municipalities to receive shared revenue payments when a utility-owned battery energy storage system (BESS) is located within their borders. These payments are referred to as utility aid and will amount to $1,000 per megawatt of storage capacity. Local governments also receive utility aid payments for utility-scale renewable energy projects and energy-producing projects.

Utility aid payments are intended to help local governments offset lost property tax revenue and actually provide more funding to municipalities and counties than the property taxes would have. Property owned by a utility company is tax-exempt.

Beginning in 2027, the bill requires the distribution of utility aid payments to local governments for any energy storage facility with a capacity of at least one megawatt. In order for a BESS to qualify for utility aid, it must be used to store a power source that has been converted from another stored energy source. As an example, solar or wind.

It is becoming increasingly common that utility-scale solar is paired with a BESS. Energy storage adds reliability and flexibility to our energy infrastructure, in part by capturing excess power produced by solar installations in the middle of the day and making it available when needed.

Under existing law, when an energy project is located in a city or village, the municipality receives two-thirds of the utility aid, and the county receives one-third. If the project is located in a town, that allocation is reversed. The same will be true for how utility aid payments from a BESS are distributed.

This law was passed with the support of Wisconsin utilities as well as energy developers that are active in the state. This change is a win for communities that host the energy projects that keep our lights on.

RENEW Wisconsin Supports Bent Tree North Wind Project

RENEW Wisconsin Supports Bent Tree North Wind Project

by | Mar 2, 2026 | Advocacy, Renewables, Utility Scale, Wind

Wisconsin Power and Light (Alliant Energy) plans to expand its Bent Tree Wind Farm with the Bent Tree North Wind Farm project. Though located in Minnesota, the project will provide power for Alliant Energy customers here in Wisconsin. RENEW Wisconsin is advocating for approval of this project both in Minnesota and here in Wisconsin, as Alliant Energy requires approval from both the Minnesota Public Utilities Commission and the Public Service Commission of Wisconsin.

In its first full year of electricity production, Bent Tree North Wind Farm will produce about 550,000 Megawatt-hours (MWh) of electricity. This is enough to power 55,000 Wisconsin households and reduce emissions produced from energy production by more than 865 million pounds of Carbon Dioxide (CO2) each year. This amount of CO2 would be like taking more than 85,500 vehicles off the road.

Along with CO2 emissions, there are a slew of pollutants that this project will keep out of the air we breathe. As a result, Wisconsin can expect over $1.8 million in economic benefits associated with public health improvements in the first year of Bent Tree North Wind’s operations.

Similar to Wisconsin, Minnesota communities that host utility-scale energy projects benefit from these projects. Bent Tree North will add 150 Megawatts (MW) to the already existing Bent Tree Wind Farm, a 201 MW project. In Minnesota, wind projects are subject to a Wind Energy Production Tax. At about $19,000 per turbine, Bent Tree North will add nearly $650,000 in revenue to be split among Steele, Waseca, and Freeborn Counties. Additional financial benefit will go to the landowners who are leasing their land to make this project possible.

The construction of the project is expected to create 100 to 150 full-time jobs until the project is operational. Additionally, construction workers will contribute to local spending for housing, fuel, meals, and supplies, and construction materials such as concrete and gravel are often sourced locally or regionally.

Though we don’t typically extend our advocacy beyond the borders of our state, this is a great opportunity for both Wisconsin and Minnesota, even if we can’t see eye-to-eye on where Paul Bunyan’s Axe really belongs. Rivalries aside, we look forward to seeing this project approved and will provide an update when we know more!
