Virtual Power Plants Can Produce Real Results for Wisconsinites

Virtual Power Plants Can Produce Real Results for Wisconsinites

by | Jul 30, 2026 | RENEW Wisconsin, Utilities

In early July, the U.S. power grid experienced a heat dome that drove Americans’ energy usage to an all-time high. 

There is little doubt that heat waves fueled by climate change, coupled with the rising power use of data centers, will increasingly strain the electrical grid, likely driving up consumer costs even further. 

So, what can we do? Virtual power plants offer a real solution where customers can work with power providers to reduce demand for energy and use it efficiently — cutting costs for both consumers and utilities.

At the most basic level, virtual power plants (VPPs) are a network of energy users and suppliers that use existing energy resources in the community and within people’s homes to provide power to the grid—and to strategically reduce energy demand during periods of peak use.

VPPs can be managed by private technology or renewable energy companies, regulated utilities, or other program operators. To manage energy use, VPPs use various devices and technologies that create, store, and use power. This can include rooftop solar, electric vehicles (EVs), home and industrial-scale batteries, smart thermostats, water heaters, and other similar energy systems.

By managing these resources throughout the day as power demand rises and falls, VPPs ensure reliable power while producing energy savings and rewards for participating consumers.

Because they reduce peak power demand and enable a more flexible power grid, VPPs have the potential to reduce or eliminate the need to build expensive and polluting fossil fuel infrastructure.

Preventing these new gas-powered plants from being built eliminates the risk that utility customers, who are already burdened by recent energy rate increases, will be asked to pay for stranded fossil fuel infrastructure as Wisconsin transitions to a clean energy economy.

Particularly as large data centers drive a projected 40 percent increase in energy use by 2032, expanded VPP programs will be necessary to supply reliable power, reduce the health impacts of dirty fossil fuel plants, and keep Wisconsin on track for our 2050 carbon-free energy goal.

VPPs in Your Home

In areas where demand response programs are available, customers can voluntarily install smart thermostats, heat pumps, and other devices in their homes that can be managed remotely by the VPP operator. The operator can then reduce demand and draw excess energy to other users, in exchange for compensating the customers, often via bill credit.

VPP systems have begun to catch on throughout the United States, including in Chicago, where a smart thermostat VPP program was recently approved, slated to begin in May 2027. ComEd, the utility serving northern Illinois, will manage the Chicago program and utilize smart thermostats voluntarily installed by consumers. The program is estimated to save $60 per year for the average household.

So, what would the program look like in your home? Let’s say it’s a particularly hot August day, and your thermostat is set to 70 degrees to keep your house comfortable. A VPP operator may increase your house’s temperature to 73 degrees to reduce energy demand during the afternoon or early evening when energy consumption is high, and the energy grid is under stress.

Making this small change across thousands of homes will significantly reduce energy use and relieve stress on the grid. In exchange, you will receive a bill credit for allowing your thermostat to be remotely controlled.

In 2025, a brutal heat wave hit Vermont. But Green Mountain Power, the region’s utility, sourced power from customers’ batteries distributed across the state, reducing the need to buy expensive peak demand energy. Ultimately, the VPP saved consumers an estimated $3 million in energy costs for just one day — roughly $10 per customer.

RENEW’s Role in the VPP Revolution

Here in Wisconsin, RENEW Wisconsin is working to expand consumer access to rooftop solar systems, making it easier and more financially viable to install a miniature solar energy plant on your property.

Additionally, RENEW advocates for expanded consumer EV and Bring Your Own Device (BYOD) programs that reflect the value of consumers reducing their demand, connecting consumers to the energy system, and enabling customers to exert greater control over their energy — reaping the financial reward when they reduce energy consumption.

Wisconsin’s statewide energy efficiency program, Focus on Energy, provides $50 rebates on qualified smart thermostats across nearly all utilities in Wisconsin. Some utilities also offer demand response programs that are compatible with utility-eligible smart thermostats. These utility smart thermostat programs manage cooling during peak times and provide rewards or bill credits for customer participation.

WE Energies just unveiled a summer program that offers new participants $50 for allowing the utility to adjust their thermostat for up to four hours, with the option for customers to override the adjustment. Returning customers can get more than $6 per month for their participation, shaving a few dollars off their monthly bills.

Another example of a demand response program is WE Energies’ pilot EV program, which gives consumers credit for charging their EVs between 12 am and 8 am, when energy demand is low.

RENEW also advocates for consumers to get monthly bill credits for participating in demand response programs, such as Madison Gas and Electric’s smart thermostat and smart water heater programs. Monthly credits, as opposed to annual bill credits or gift cards, enable consumers to readily see how their participation is reducing energy demand and enabling grid flexibility.

In the future, RENEW will continue to advocate for utilities to make these programs permanent, larger, and more comprehensive — linking together thermostats, EVs, batteries, and rooftop solar to create a smart, responsive energy system for Wisconsin, powered by renewable energy and clean technology.

Doing so will reduce the need for outdated fossil fuel infrastructure, lower customers’ energy bills, and help meet all of Wisconsin’s growing power needs.

The Great Wisconsin Energy Road Trip

The Great Wisconsin Energy Road Trip

by | Jul 20, 2026 | RENEW Wisconsin, Renewables

Imagine Wisconsin is about to take the most ambitious road trip in its history.

The destination? A future where the lights stay on, electric bills are affordable, businesses have the power they need to grow, and the air is cleaner than it is today.

Three people walk up to the driver’s seat and say, “I know the best way.” But they all want to take a different route.

Mandela Barnes: “Let’s Build Opportunity.”

Barnes looks out the windshield and says, “This trip should help everyone.”

His path focuses on creating good-paying jobs, expanding clean energy, and making sure the benefits reach working families and communities that have often been left behind.

His message is simple: Wisconsin can grow its economy while building more renewable energy.

Francesca Hong: “Let’s Build the Highway of the Future.”

Hong unfolds what appears to be the largest map anyone has brought. She talks about adding more solar and wind farms, more battery storage, and a stronger electric grid. She also wants Wisconsin to plan ahead rather than wait until there’s a problem.

When giant new electricity users, like AI data centers, move into Wisconsin, she argues they should pay for the new power plants and transmission lines they need, rather than sending the bill to everyone else.

Her route is ambitious and detailed.

Tom Tiffany: “Don’t Fix What Isn’t Broken.”

Tiffany eases off the gas and says, “Slow down.” Tiffany wants to pump the brakes on utility-scale renewable energy projects. His alternative? Wisconsin should lean into fossil fuels and add more nuclear energy generation to the mix to meet our energy needs and keep prices low.

Renewable energy could have a place on his map, but he believes nuclear energy and fossil fuels are what’s needed to meet Wisconsin’s energy needs.

More on The Candidates’ Energy Plans

Though RENEW has a preference for a route that includes the most renewable energy possible, that doesn’t automatically make the plan we prefer the “best” plan for every voter.

Francesca Hong

Hong brings the most complete blueprint to the table. Her plan covers renewable energy from nearly every angle—expanding solar and wind power, adding battery storage, strengthening the electric grid, improving energy efficiency, and planning for Wisconsin’s future energy needs. She also explains who should help pay for new infrastructure.

 Mandela Barnes

Barnes strongly supports renewable energy and clean-energy jobs. His vision is optimistic and focuses on creating opportunities for working families. While his goals are clear, his publicly released energy strategy contains fewer specific details about how those goals would be achieved.

Tom Tiffany

Tiffany’s focus is different. He believes that expanding nuclear power and relying on fossil fuels will drive down energy prices. Renewable energy might be part of his approach, but it is certainly not the centerpiece of his energy strategy. Because this report card grades only renewable energy policy, he receives the lowest score.

The Destination

Every candidate agrees on one thing:

Wisconsin needs more energy.

Where they disagree is how to build it, who should pay for it, and how quickly the state should move toward renewable energy.

As with every road trip, there are different routes to the same destination, but it’s up to the people of Wisconsin to decide who gets the keys.

*This blog post is not a candidate endorsement and includes the top three polling candidates at the time of publication. We encourage everyone to research the policies of each candidate and make their own decision on who has the best plan for them.

When the Sky Turns Orange, It Changes the Conversation About Energy

When the Sky Turns Orange, It Changes the Conversation About Energy

by | Jul 17, 2026 | Advocacy, RENEW Wisconsin

Over the past week, millions of people across the Midwest and East Coast have stepped outside to hazy skies, smelled smoke in the air, and checked their weather apps—not for rain, but for the Air Quality Index (AQI).

For many communities, the AQI has climbed from “Unhealthy for Sensitive Groups” to “Unhealthy” and even “hazardous” categories because of wildfire smoke drifting south from Canada.

The culprit is PM2.5—fine particulate matter measuring 2.5 micrometers or smaller. These particles are so small that they can travel deep into your lungs and even enter your bloodstream. They’re associated with increased asthma attacks, heart disease, strokes, respiratory illness, and other serious health concerns.

We often talk about building an economy and a clean energy future we can afford, focusing on the cost of producing energy and the size of people’s energy bills. In this case, the discussion shifts to what we can’t afford. We can’t afford to keep making the choices that have turned these smoky summer days into a new normal.

Those decisions have not only brought us to this moment, but have been producing the same type of pollution driving today’s air quality alerts. PM2.5 is also one of the primary pollutants produced when coal is burned to generate electricity. Coal-fired power plants also emit sulfur dioxide (SO₂) and nitrogen oxides (NOₓ), which can react in the atmosphere to create even more fine particulate pollution.

To be clear, not every wildfire is directly caused by climate change, but our choice to rely on fuel sources like coal and natural gas makes it more common. What’s worse is that our continued reliance on coal plants continues to regularly expose nearby residents to fine particulate pollution that can harm our health. The same kind of air pollution that much of the country is being exposed to right now. 

Every time smoke fills our skies, we change our behavior. We keep our children indoors, cancel outdoor events, run air purifiers, and hope the wind shifts. Unfortunately, those who live near coal plants don’t have the benefit of waiting for the winds to change.

It reminds us of something we often take for granted: Clean air matters.

That is why RENEW Wisconsin works every day to expand renewable energy across our state.

Every new solar array, every wind project, every battery installation, every clean energy policy we advance is about more than electricity. It’s about protecting the air we breathe, strengthening our economy, creating jobs in Wisconsin, and building an energy system that doesn’t rely on harmful combustion to keep the lights on.

This work doesn’t happen by accident.

It happens because people like you believe Wisconsin deserves a cleaner, healthier, and more resilient energy future.

If you’ve ever wondered whether your support makes a difference, it does.

Your donation helps RENEW Wisconsin:

  • Advocate for clean energy policies at the Capitol and before state agencies.
  • Support the responsible development of wind, solar, and energy storage.
  • Expand access to renewable energy for schools, nonprofits, and communities.
  • Educate the public with trusted, fact-based information.
  • Build a healthier energy future for every Wisconsin family.

The next time you look outside and see a hazy sky, remember that while we can’t stop every wildfire, we can choose how we generate the electricity that powers our lives and build the future we want to see.

If you believe, like us, that we can’t afford to continue to rely on the energy sources that got us into this mess, I invite you to support RENEW Wisconsin today.

Together, we can build a state where clean air isn’t something we hope for—it’s something we protect.

Donate today and help power Wisconsin’s clean energy future.

Wisconsin’s Climate Youth is an Energy Wakeup Call for Wisconsin

Wisconsin’s Climate Youth is an Energy Wakeup Call for Wisconsin

by | Jul 8, 2026 | RENEW Wisconsin, Renewables

Across the country, youth impacted by climate change have sued state governments on the theory that inaction in the face of the climate crisis violates their fundamental constitutional rights.

In one highly publicized case, Held v. State, 16 kids sued the State of Montana over environmental laws that shielded companies developing fossil fuel projects, forbidding the state from reviewing the full impacts of the projects’ greenhouse gas (GHG) emissions.

The youth litigants won a decisive court victory, striking down that provision of the Montana Environmental Policy Act and securing a declaration of their constitutional right to a “stable climate system.”

More recently, the Montana plaintiffs are back in court in 2026 seeking to reinforce their win and ensure Montana’s energy and environmental policy actually complies with the established right to a stable climate.

Wisconsin’s Youth Climate Case

Here in Wisconsin, the nonprofit legal advocacy group Our Children’s Trust teamed up with Midwest Environmental Advocates (MEA) to sue the state’s Public Service Commission (PSC) and the state legislature in 2025 in Dunn v. Wisconsin Public Service Commission.

In their complaint, the young plaintiffs — ranging from age 8 to 17 at the time the case was filed — challenged aspects of Wisconsin energy law that allow utilities to continue building fossil-fuel infrastructure despite the climate crisis.

The youth plaintiffs hail from a wide range of backgrounds, but they all share one tragic bond: climate change is making their lives measurably worse.

The climate crisis has forced some of their families to move, rendered many Wisconsin rivers and lakes degraded and unfit for swimming, fishing, and boating, robbed them of opportunities to engage in cultural activities like tapping maple trees for maple syrup, exposed them to a heightened risk of Lyme disease, exacerbated health issues like asthma, and led to a decline in their mental health.

Driven by these cultural, health, and economic impacts, many of these kids and young adults have dedicated themselves to climate education and activism.

But they can’t do it alone — they will need help from engaged Wisconsinites to push our legislators and courts to consider the true costs of continuing to develop more fossil fuel infrastructure when renewable energy alternatives are readily available.

The Youths’ Argument

In court, plaintiffs argued that the law prohibiting the PSC from considering the impacts of air pollution in issuing Certificates of Public Convenience and Necessity (CPCNs) to large energy projects is unconstitutional, allowing the continued development of fossil fuel projects without considering their full costs to society.

Second, the youth argued that Wisconsin’s Renewable Portfolio Standard (RPS) is unconstitutional, effectively putting a ceiling on the PSC’s ability to push utilities to supply more renewable energy.

In 2005, Wisconsin amended Act 9, setting an initial goal of 10 percent renewable energy by 2015. That goal was first met back in 2013, two years ahead of schedule. Since then, the PSC has been unable to require more renewable energy to support our statewide climate goal, or even accurately track the renewable energy portfolio of Wisconsin’s utilities. This shortcoming has led Wisconsin to fall behind in the adoption of renewable energy.

Without the ability to mandate that utilities develop more renewable energy, Wisconsin will struggle to meet the long-range 2050 goal of 100% carbon-free energy set by Governor Evers.

The plaintiffs argue that these maladies in Wisconsin law are violating their foundational rights to life and liberty, which rest on a stable climate system.

They also argue that the defendant’s inadequate response to climate change was violating Wisconsin’s Public Trust Doctrine and depriving plaintiffs of the ability to use and enjoy Wisconsin’s bountiful water resources: our many public rivers and lakes. Sadly, Wisconsin’s public waterways are increasingly degraded by extreme heat and algal blooms closely linked to climate change.

The Lower Court’s Ruling

Despite a load of evidence, the plaintiffs’ case was dismissed by the court. While the judge sympathized with the youth, acknowledging that the plaintiffs showed clear harm from climate change, they decided that this case is not fit for resolution in a courtroom.

Instead, the court said the plaintiffs’ cause is an energy policy issue that would be better addressed in the state legislature.

However, the plaintiffs are appealing that decision and fighting to bring awareness to the human impacts of the climate crisis, and to push Wisconsin to take meaningful action to mitigate climate change and protect the future of all Wisconsinites.

The High Cost of Fossil Fuels

The natural gas plants that Wisconsin utilities and power producers are currently building and proposing will operate for 30 or more years, producing a wide range of serious, negative environmental health impacts for Wisconsinites.

Natural gas and coal plants struggle to compete with solar and wind power on costs, and that’s not including the often-ignored economic and health costs of fossil fuel projects, which include dirtier air, a slew of health risks, and early death.

In 2025, WE Energies received PSC approval for two massive natural gas plants, Oak Creek and the Paris Generation Project.

While some have touted natural gas as a cleaner “bridge” fuel, analysis conducted by Healthy Climate Wisconsin and the Union of Concerned Scientists predicts that the plants will cost more than $5 billion in health impacts from particulate, sulfur, and other forms of toxic pollution over their three-decade lifespan, with impacts in Wisconsin and neighboring states like Michigan.

These new plants will particularly harm people with existing heart or respiratory issues, as well as communities that have already borne the hefty costs of fossil fuel development.

Overall, Wisconsinites will be less healthy as a result of these natural gas projects, in addition to the broader impact on climate change from burning methane — a greenhouse gas far more potent than carbon dioxide.

The roughly $2 billion WE Energies is spending developing the Oak Creek and Paris projects could have been used to build large-scale solar or wind farms that would have provided clean, reliable energy.

Wisconsin’s Clean Energy Future

With the technology we have available, there is no need for more outdated, dirty fossil fuel infrastructure in Wisconsin.

RENEW Wisconsin is fighting to put solar and wind on level ground with fossil fuels — because solar and wind power prevail when they are given a fair chance to compete in the energy market.

A brighter and attainable Wisconsin energy future powered by renewable energy would produce reliable power, create jobs, and lessen air pollution, leading to a healthier and wealthier Badger State.

A combination of rooftop, community solar, large-scale solar, energy conservation, smart demand reduction programs, and battery storage can meet all of Wisconsin’s energy needs, even with the projected increase in energy demand from data centers.

That is the future RENEW Wisconsin is fighting for.

RENEW Wisconsin Summit Panel: A Timely Conversation on Siting

RENEW Wisconsin Summit Panel: A Timely Conversation on Siting

by | Jun 26, 2026 | Community, RENEW Wisconsin, Renewables

Communities across Wisconsin continue to grapple with how renewable energy projects get sited and permitted. At our 2026 RENEW Wisconsin Summit RENEW Wisconsin hosted a panel that brought together expert voices on state and local siting and permitting authority. The conversation is worth a revisit, as the industry continues to navigate this important topic.

Eric Callisto, a former Chair of the Public Service Commission of Wisconsin (PSC) and private-sector renewable energy attorney, made a clear case for why state-level oversight of large projects matters: projects that serve the regional grid are matters of statewide concern, and an independent expert agency is better positioned to evaluate energy projects than individual town boards. He was candid that without that independent oversight, the “NIMBY element” would prevent many worthy projects from being built.

Orrie Walsvik, an associate attorney at Michael Best, walked through what he called the “inverted pyramid” of clean energy regulation, from baseline zoning to the case-by-case requirements of § 66.0401 to the PSC’s comprehensive authority over 100+ Megawatt projects. His core point: local governments have been delegated administrative authority to help Wisconsin implement its renewable energy policy, not the legislative authority to decide whether that policy is welcome in their jurisdiction.

Isaac Uitenbroek, a zoning administrator with direct experience drafting and implementing solar regulations, provided an honest window into what local government staff navigate: constituent pressure, tight timelines, and the balancing act of building ordinances that meet legal requirements while giving elected officials a process they can use to address community concerns. He advised developers and applicants to communicate early, communicate often, and leave no information vacuum. His perspective reflected real experience with what happens when communities feel blindsided.

David Jakubiak, Senior Vice President of Aileron and expert on renewable energy communications, reinforced that community engagement is not a compliance checkbox but a prerequisite for project success. He pushed back on drone footage, cookie-cutter community meetings, and out-of-state project representatives and witnesses. David made the practical case for finding local champions and showing people what renewable energy actually looks like from the road, not from the sky.

The common thread of the panel discussion and audience question was a recognition that Wisconsin is navigating a genuine policy contest, one requiring developers, lawyers, and local governments to work together to find a workable path that recognizes community concerns and appreciates the local benefits of renewable energy development.
