On Sunday, November 9, 2025, Holy Spirit Parish in Stevens Point welcomed parishioners, families, students, and community members for a ribbon-cutting celebration marking the completion of two new solar arrays. The event highlighted the parish’s commitment to caring for creation and investing in the future of its congregation and school.

The project was supported through the Solar for Good program, funded by the Couillard Solar Foundation and managed by RENEW Wisconsin. Olson Solar Energy served as the installer and guided the parish through the technical, insurance, and design steps needed to bring the project forward.

Guided by Faith and Stewardship

The idea for the solar project began within Holy Spirit Parish’s Environmental Stewardship Committee. Their members shared that a central belief guided them through each stage of planning and conversations with parish leadership.

“Faith calls us to be stewards of the land, and that means the planet is part of what we are called to care for.”

This perspective shaped the committee’s vision and helped carry the parish through a process that required patience and collaboration. Insurance reviews and utility requirements brought several design changes, and the team worked closely with Olson Solar Energy to adapt and keep the project moving.

Collaboration and Commitment

“This really was the work of so many people. It took time, effort, and a lot of expertise from members of our congregation. Everyone played a part, from researching and planning to helping with outreach and fundraising. It is something we can all be proud of because it truly belongs to this community,” said Susan Zach, a member of Holy Spirit Parish’s Environmental Committee.

The project was originally planned as a single array on the church roof. As design and interconnection requirements evolved, the plan expanded to include a second array on the school. Olson Solar Energy worked with the parish through each iteration, helping resolve insurance questions, coordinating two separate meters, and staying flexible as the project shifted. Their responsiveness was referenced several times during the event.

A Project That Gives Back and a Community Celebration

Both systems are under 20 kilowatts, allowing the parish and school to qualify for net metering and receive credits on their energy bills. Olson Solar Energy estimates that the project will save the parish and school about $100,000 in avoided energy costs over the life of the system. These savings will support classrooms, programs, and facility improvements that strengthen Holy Spirit Parish and School.

During the celebration, parish leaders and school staff reflected on the project’s journey and the teamwork that carried it forward. It was clear from the gratitude shared throughout the room that this project was rooted in community. A strong sense of place, care for creation, and pride in working together shaped every step of the process.

“We are proud to be the first Catholic parish in the La Crosse Diocese to install solar on our property. This project reflects both our faith and our responsibility to care for the gifts we have been given. It is our hope that others in the diocese will see what is possible and join us in taking steps toward sustainability,” said Fr. Steve Brice, pastor of Holy Spirit Parish.

On December 1, 2025, new rules from the Public Service Commission of Wisconsin (PSC) will take effect, modernize how electricity is metered in multifamily housing and mobile home parks. This update represents a major win for clean energy and affordable housing advocates as well as for developers across the state.

RENEW Wisconsin, Clean Wisconsin, Elevate, Dane County, the City of Madison, the Wisconsin Local Government Climate Coalition, the Union of Concerned Scientists, and many other advocates and developers submitted comments supporting the change. Together, these groups urged the PSC to update outdated language to make it easier to design affordable, energy-efficient, and renewable-ready multi-family housing.

The rule, originally adopted in 1980 to comply with the Public Utility Regulatory Policies Act (PURPA) of 1978, had not been substantially revised since 2002. It was intended to promote energy conservation by requiring every dwelling in a multi-unit building or mobile home park to have its own electric meter. While well-intentioned, the rule eventually outgrew the technology of its time. It began to restrict new energy-saving methods such as shared solar, geothermal heating, and high-efficiency heat pumps.

The updated PSC 113.0803 rule now establishes clear standards for when individual meters are not required. Multifamily or mobile home park projects can qualify if:

• High-efficiency equipment: Tenant-controlled systems meet Focus on Energy or federal efficiency standards, and projected energy use per unit is less than half the statewide average, factoring in onsite renewables.
• High-efficiency design: Newly constructed buildings meeting advanced performance standards through programs like Focus on Energy automatically qualify.
• Affordable housing participation: Buildings under contract with local, state, or federal affordable housing programs are eligible.

This rule change will open new opportunities for solar, geothermal, and other clean energy technologies, reduce administrative delays, support affordable housing, and expand Wisconsin’s pathway toward clean economic growth. This change opens up new avenues in our all-of-the-above approach to deploying renewables and ensures everyone in the state can benefit from clean, reliable energy.

Clean Energy Works is RENEW Wisconsin’s initiative to get into the field with our business members and learn directly from those doing the work each day. By shadowing installers, technicians, and staff across the clean energy industry, we gain a deeper understanding of what goes into the work. These experiences directly inform how RENEW supports and advocates for the people and companies driving clean energy forward.

The heart of many Wisconsin communities is the local school district, and that is certainly true in Amherst. When Amherst High School decided to install a rooftop solar array, it was not just about saving money on energy. It was about helping students see renewable energy in action every day. Through the Solar on Schools program, supported by the Couillard Solar Foundation and administered by the Midwest Renewable Energy Association (MREA), the district added a solar system that both powers the school and offers hands-on educational value.

To see how this project came together, I joined Isaiah “Zay” Miller, Commercial Project Manager at Northwind Solar, a worker-owned cooperative based in Amherst, WI.

Meet the Crew

Zay’s path into solar started with curiosity and a willingness to learn. He got his start in 2018, doing mostly residential rooftop installations with almost no construction experience under his belt.

He quickly found his footing at Northwind. Within a few months, he was leading the DC side on commercial projects, later moving into Field Manager and Project Manager roles. Today, he oversees commercial systems and handles much of the design work.

Having worked in nearly every position in the company, Zay brings a deep understanding of what it takes to install systems safely and efficiently.

Before joining Northwind, Zay studied ecological engineering at Oregon State University. His background in water systems gave him a useful way to think about energy. “It’s all systems thinking,” he said. “How water moves, how power moves, it’s just a different medium.”

At around 7 years with Northwind, Zay is now a member-owner of the company. Northwind operates as a worker-owned cooperative, which shapes how the company approaches its projects.

“You have to work here for two years before you can buy in,” Zay said. “The cooperative model means we make decisions together. It’s a shared responsibility.”

About the Technology

The Amherst High School system was designed to match how the building actually uses power. The panels sit above the cafeteria because that section of the roof is closest to the cafeteria’s service connection and where the school’s electricity demand peaks.

Zay explained that the cafeteria experiences the highest energy demand during the day, especially around lunchtime when kitchen equipment, lighting, and ventilation are all running. The system was designed and sized to offset that exact peak. “That’s what makes the system efficient. It’s tied to real usage, not just open roof space,” he said. 

On top of the school, the array sits on a weighted mounting system designed to rest securely on the roof without drilling into it. 

“Flat roofs are never truly flat,” Zay said. “There’s always a slope for drainage, so we adjusted the racking to make sure everything sat evenly.”

Zay explained that the layout was built with flexibility in mind, allowing the district to expand the system later or connect to another service point if they decide to increase their solar capacity.

Why It Matters

For Zay, the Amherst project shows how clean energy can fit naturally into community spaces. “This work builds community,” he said. “It’s local jobs, local power, and you can see what you’ve built every time you drive by.”

He also emphasizes that success in solar depends on strong trade skills and an eye for detail. Carpentry, measurement, and problem-solving often matter more than electrical training at first. Many of the best installers, he noted, come from farming, construction, or mechanical backgrounds where those instincts are second nature.

Zay sees solar installation as a skilled trade that blends craftsmanship, teamwork, and purpose. Many of the people he works with come from different backgrounds and discover the field by chance, but stay because the work is meaningful. As he put it, “Being able to think ahead and problem-solve is what separates a good installer from a great one.”

Looking Ahead

Zay sees a future where solar projects continue to connect people to both energy and place. He is particularly interested in the potential of agrivoltaics, an approach that allows land to be used for both solar generation and agriculture. By combining the two, solar arrays can produce clean energy while also supporting crop growth and improving soil health. To Zay, this kind of dual-purpose design shows how renewable energy can work in harmony with Wisconsin’s agricultural roots rather than compete with them.

He also sees value in bringing policymakers and educators closer to the field. “It’s great when people from the policy side come out here,” he said. “A lot of the challenges we deal with, like permitting delays or utility rules, aren’t visible from an office.”

As Amherst High School’s system begins generating power, it reflects the kind of thoughtful design and craftsmanship that defines Northwind’s approach. For Zay, it is another example of what good planning and teamwork can accomplish.

“At the end of the day, we’re just trying to build good systems and do right by our customers and our team,” he said.

If you are part of this work and would be willing to share your story, I would love to join you for a day. Feel free to reach out to me at ben@renewwisconsin.org.

When you step into a school, hospital, or office building, you probably notice if it feels bright, fresh, and comfortable. What you do not see are the systems behind the walls and above the ceilings that make that comfort possible. Mike Barnett, a mechanical engineer with a passion for the environment, has built his career making sure those systems not only function well but also contribute to a healthier future. At HGA, a national architecture and engineering firm with a strong presence in Wisconsin, Mike works within the Building Performance group to ensure that buildings are efficient, sustainable, and designed for people to thrive.

Meet the Crew

For Mike, the path into this work started with a question: how do you connect technical expertise with sustainability? With a degree in mechanical engineering and a minor in environmental studies, he had both the technical training and environmental awareness, but his first job out of college didn’t provide the connection he wanted.

“I moved back to Madison and found a position that combined my interests for the technical and sustainable, working with building owners to make their buildings more efficient,” Mike said. 

His return home marked the beginning of a career that perfectly balances curiosity with impact. “Building systems are more than just the sum of their parts. Systems need to work together in an efficient manner,” Mike explained.

He thrives on the challenge of integrating heating, cooling, lighting, and airflow so that a building feels effortless to those inside it. And while the technology is complex, the work is rooted in relationships. Those partnerships, built one project at a time, are what make his work meaningful.

“I have really enjoyed collaborating with tradespeople over the years on solving complicated problems related to HVAC controls in commercial buildings,” he said.

About the Technology

HGA’s Building Performance group has a simple but essential mission: To make sure the systems perform the way they were intended. A central part of this work is commissioning. Commissioning is one of the last steps in the building process. It involves testing a building’s systems once construction is complete to confirm everything works the way it was designed. That can involve checking HVAC airflow, verifying that lighting and controls respond properly, or ensuring the building envelope is sealed against leaks.

Mike describes it as “not a very well-known aspect of the construction process, but I have come to appreciate how important commissioning is to realizing the original sustainability and energy goals of a project.”

On one hospital project, Mike explained that his team discovered a hidden air leak between an operating room and a main clinic space. If left unresolved, the leak could have spread contaminated air, threatening patient safety and sanitation. Because it was caught during commissioning, the issue was fixed before the hospital opened. For Mike, moments like this prove why commissioning is essential: it prevents costly problems, protects health, and ensures buildings truly deliver on their sustainability and energy goals.

Why It Matters

Mike knows that sustainable design is only successful if it is embraced by leadership. It’s his opinion that sustainability has to be a priority of the leaders of that organization. That is why he always frames the benefits in ways that resonate. In schools, it means healthier classrooms and lower operating costs. In hospitals, it is about better patient care and stronger staff retention.

One standout project for Mike is Forest Edge Elementary, the state’s first all-electric net-zero school. The school not only reflects the district’s long-standing environmental values but also delivers lasting savings.

“Oregon School District has always been a strong advocate for environmental sustainability, and Forest Edge continued to be a concrete example of the district living its values and doing so in a way that provided long-term financial savings to the district,” Mike said. “I’d love to turn back time and attend elementary school at Forest Edge!”

For Mike, these projects are about more than technical achievement. “At the end of the day, we do this so people can thrive in better spaces,” he said.

Looking Ahead

As buildings become more efficient in their daily operation, Mike sees attention shifting toward the carbon footprint of the materials themselves. HGA is already at the forefront, designing with mass timber and committing to SE 2050, a national pledge to achieve net zero embodied carbon in structural systems by 2050.

“As buildings continue to operate more efficiently and utilize clean energy as their fuel, embodied carbon will receive more attention as building owners continue to find ways to lower their carbon footprint,” Mike said.

Just as important is Mike’s desire to inspire others to step into this work. They could do this by getting involved in their local community. Mike has found that there are many great opportunities to get exposed to sustainability in buildings. His local high school’s green team, which spearheaded the installation of solar panels, is one example. For him, it is a reminder that leadership can come from anywhere.

“Even if they do not have aspirations to work directly in the field of architecture, there are opportunities to lead on sustainability,” Mike said. “We all have influence over the collective decisions we make at the organizations we work at and the communities we live.”

Battery storage is a newer part of residential clean energy, and is slowly becoming an important way for homes to manage power. We use batteries every day, whether in our phones, laptops, or cars. Now that same technology is being installed in Wisconsin homes to help families stay resilient during outages and make the most of the solar energy they produce, even after the sun goes down.

To see how an installation comes together, I spent the day with the crew at Home Team Energy. They are a tight-knit group of seven employees based in Brookfield, Wisconsin, completing about 100 projects a year since opening in 2019.

On this job, I followed Stefan and Josh as they installed a Tesla Powerwall in the basement of a newer home outside Burlington.

Meet the Crew

Stefan began his career in northern Minnesota doing residential electrical work. Moving to Wisconsin gave him the chance to keep doing what he loved while stepping into an industry with room for advancement. Home Team Energy provided the path for him to earn his master electrician license. 

On this job, that expertise showed in the way he worked with both the battery panel and the home’s main electrical panel open. This setup let him see exactly how each system and component connected, ensuring the wiring was installed correctly and the disconnects were set to meet electrical and building codes. 

As he worked, he explained each step, highlighting how these details keep the system safe, reliable, and ready for inspection. He made sure everything fit neatly on the homeowner’s wall so it looked like it belonged there. He pointed out how they were planning to run the conduit, the reasons for running it where it needed to be, and how they were making efficient use of equipment. Every line was leveled, the wiring was tidy and presentable, and everything was ready to meet the requirements for inspection later that day.

Josh grew up in Waukesha and Lake Geneva before moving to California to work in a high-volume solar market. He eventually returned to Wisconsin to be closer to family and the communities he knew well. On the job, he measured and cut conduit so the line from the roof to the electrical meter and into the basement would be straight, clean, and easy to follow. His precision ensured the installation looked as good as it performed.

As we worked, the conversation turned to their love of Wisconsin’s outdoors. They traded stories about trout streams, favorite fishing spots, and the quiet places in state parks where they hunt in the fall. 

About the Technology

The Tesla Powerwall is a rechargeable home battery that stores energy for later use. It can be charged from solar panels or directly from the grid. When solar panels produce more power than the home needs, the extra energy goes into the battery. Later, when the home needs electricity, especially during the evening when demand is high, the battery supplies that power instead of drawing it from the grid.

This is where the home and the grid work together. For example, on a hot July evening when air conditioners, TVs, lights, and electric stoves across the neighborhood are turned on, this Burlington homeowner can run their home on energy stored in the Powerwall earlier in the day. That means they are not pulling from the grid during its busiest hours, which reduces strain on the system and frees up power for their neighbors.

At rural homes like this one, batteries are especially valuable. They provide backup during outages, keep essential systems running, and offer peace of mind in places where grid reliability can be less certain.

Why It Matters

Battery storage benefits more than just one home. It supports the neighborhood by reducing strain on the grid during high-demand times. This Burlington installation will help the homeowner use their own clean energy while also supporting the wider system.

Clean energy also pulls and keeps talent. Contractors like Home Team Energy, along with other RENEW Wisconsin members, attract skilled workers from other states, bring experienced people back to Wisconsin, and provide high-paying careers that keep those workers here. These jobs bring in people who want to build something meaningful while staying connected to their communities.

Looking Ahead

Battery storage is becoming a central part of Wisconsin’s clean energy future. Systems like the Tesla Powerwall allow homeowners to use solar power when it matters most, provide backup during outages, and prepare for future utility programs such as virtual power plants and advanced grid management.

My day with Home Team Energy was not only about the technical side of the installation. It was about Stefan explaining the “why” behind each choice, Josh taking the extra moment to make each cut exact, and both of them speaking about the land, water, and wildlife they want to protect. These systems are more than equipment on a wall. They represent the work of skilled people building a cleaner, stronger energy future for Wisconsin, one home at a time.

When you think about Wisconsin’s clean energy jobs, it is easy to picture panels, wires, and policy charts. But the real story starts with people.

On a crisp spring morning, I joined a crew from Arch Solar as they set out to bring another rooftop solar project to life. They were a small team, each person coming from a different background: Dave, who leads the panel installs, once packed clothes at Lands’ End. Billy, two months into the job, fixed bikes in Fond du Lac. Leo, now installing panels with the crew, poured concrete in Milwaukee. Jenny, one of the lead electricians, farmed organically near Plymouth before entering the trades. TJ, now a master electrician, once trained for the police academy.

These are the people building Wisconsin’s clean energy future, one project at a time.

The Crew on Day One: Foundations First

The first day of the install was all about setup. I spent the full day with the rooftop solar crew, Dave and Billy, as we laid the foundation for the project. That meant attaching the structural supports and rails that hold to solar panels, along with all of the electrical infrastructure. The crew’s quick work ensured everything was set up for the next day’s panel work.

Dave, one of the lead solar panel installers, has been with Arch for a few years now, and his attention to detail is top-notch. After getting some hands-on experience in the field, he’s now hoping to enter Arch’s electrician apprenticeship program. His steady focus and thoughtful approach stood out, whether he was leveling rails, checking truss locations, setting supports, or making sure conduit was cleanly installed.

Billy, who is just two months into the job, was right there alongside him. It was immediately clear how much he had picked up in such a short time. He asked smart, timely questions and jumped into the work confidently.

While we worked on the roof, Don and Neil handled the electrical work below. Don, who is currently in his electrical apprenticeship, was paired with Neil, a master electrician. They were in charge of setting up the electrical components for the next day, and their coordination with the rooftop team was seamless. Questions moved quickly between us, and answers came easily.

The Crew on Day Two: Panels, Service, and New Faces

The second day brought new crew members and new tasks. Dave and Billy returned, and Leo joined them in handling the panel installation. It was the first time the panels were actually going on the roof, and the three of them worked with speed, care, and attention to every detail.

While the panel install team was up on the roof, I spent all of day two with the electricians, Jenny and TJ. That change in perspective gave me a full view of the project and helped round out my experience across both days. Day one was about structural layout, hardware, and module prep. Day two gave me a front-row seat to the electrical service upgrades, EV charging readiness, and system wiring that bring a solar project to life.

Jenny is a lead electrician at Arch. Before joining the team, she spent years working on an organic farm near Plymouth. Her path into the trades is a powerful example of how someone can have a long, successful career in one field and still pivot to something completely different when the time feels right. Jenny’s calm, knowledgeable presence made her a go-to for any electrical question on site. TJ, her counterpart, also took a unique path to the trades. He has thrived in his role at Arch and recently passed his master electrician exam.

This Is What a Good Job Looks Like

Clean energy conversations often focus on technology, investment, and carbon reduction. Those things matter. But being on-site reminded me that clean energy is also about people and good jobs.

Good jobs are at the heart of the clean energy transition. Jobs that pay well, teach real skills, and offer a pathway forward. Jobs for people from all kinds of backgrounds, whether from bike shops, concrete work, farming, or retail.

Everyone I met was doing skilled work they could be proud of, and every person was thinking about what came next. Whether it was Billy just getting started or TJ recently earning his master electrician license, there was a shared sense that this was about more than a paycheck. It was about building careers, strengthening communities, and creating a future they can stand behind.

Looking Ahead

For RENEW, site visits like this help us better support the people who do this work. We spend a lot of time writing comments, reviewing rate cases, analyzing permitting policy, legislative proposals, and advocating for changes at the Public Service Commission. That work is critical, but it is even more impactful when it is informed by firsthand experience.

There are more crews to meet, more technologies to explore, and more stories to tell. At the end of the day, clean energy is about the people behind it. The more we listen to them, the stronger the future we can build for the grid, for the climate, and for the communities doing the hard work.

If you are part of this work and would be willing to share your story, I would love to join you for a day. Feel free to reach out to me at ben@renewwisconsin.org.

The past few weeks have been eventful for the EV industry. Changes to NEVI funding, CFI grants, Clean School Bus grants, and discussions about altering EV tax credits at the federal level have raised questions about where things stand. With all this movement, many advocates and EV owners are wondering what the future holds.

That’s why my visit to the Chicago Auto Show last week felt so timely. This event isn’t just a playground for car enthusiasts.  It is where automakers showcase their latest models, concept vehicles, and innovative technology. It’s also a great opportunity for organizations like RENEW to see how the auto industry is positioning itself for the future.

And after walking through car manufacturer to car manufacturer, I can confidently say that EVs are still a core part of the automotive industry.

Despite political shifts and an evolving narrative around electrification, automakers are still committed. EVs were front and center at nearly every major booth. No matter where you looked, there was an EV or plug-in hybrid showcased on a stage, positioned right alongside the manufacturers’ most popular gasoline models.

Automakers Are All In

At Ford’s booth, one of the first things you saw walking into the main hall was the F-150 Lightning, the Mustang Mach-E, and Ford’s proprietary home charging setup. These displays were front and center of the Ford display, making it clear Ford still sees EVs as a priority

Over at Jeep, the focus was, as expected, all about off-roading. They had their usual rugged terrain display, showcasing the Wrangler and Gladiator’s trail capabilities. But what was running the trail with them? The Wrangler 4xe plug-in hybrid, demonstrating how combining an electric motor with an internal combustion engine enhances torque, fuel efficiency, and even allows for silent off-roading—something that was almost unheard of when it was first introduced.

The Stellantis brands (Ram, Jeep, Chrysler, Dodge) had a strong presence. Ram was showing off its new RamCharger chassis, a plug-in hybrid setup that uses a gas-powered generator to feed electricity to the battery, allowing for a range of over 650 miles. Chrysler had a brand-new luxury EV concept on display, the Halcyon. Dodge, known for their muscle cars, was showcasing their push into electrification with the all-new EV muscle car, the Next-Gen Charger. Across the board, hybrid and electric models were integrated with their gas-powered lineup.

Even Toyota, a company that’s been openly hesitant about fully embracing EVs, made a statement. While they’ve been more focused on hybrids and plug-in hybrids, than full battery electric vehicles. Toyota made it clear, through their display, they are committed to electrification.

A High-Performance Future

One of the most exciting parts of the show was the indoor EV test track. It wasn’t just about looking at the cars, it was about experiencing them. Automakers set up a track where attendees could take rides in some of the latest EVs and feel that signature instant torque and smooth acceleration firsthand. Ford, GM, Stellantis, Rivian, Volkswagen, and others were all there, letting people experience the power of electric vehicles first hand.

The Bigger Picture: Why People Choose EVs

Walking through the auto show, it became clear that automakers are designing EVs and hybrids for a wide range of drivers. Not everyone is buying EVs for the same reasons and the industry is responding to that reality.

• Some people buy an EV for cost savings, with lower fuel and maintenance costs.
• Others love them for performance with quick acceleration, off-road capabilities, and cutting edge technology.
• And, of course, many are drawn to the climate benefits, reducing their carbon footprint, and supporting the shift to renewable energy.

And honestly, it doesn’t matter why someone chooses an EV or plug-in hybrid—what matters is that they do.

At RENEW Wisconsin, our goal is to see transportation powered by clean energy. The best way to make that happen? Increase EV and plug-in hybrid adoption. Whether someone is buying an EV for fuel savings, performance, environmental benefits, or a mix of all three, the result is the same: more electric vehicles on the road and a step closer to a cleaner transportation future.

So while the headlines may suggest uncertainty in the EV market, the Chicago Auto Show told a different story. It was a story of growth, innovation, and a strong commitment from automakers to electrification. The EV industry is strong and continues to expand into new markets.

Imagine a smaller, self-sufficient version of our main electricity grid that can power neighborhoods, communities, and even single homes. That’s the basic idea behind a microgrid – a localized energy system designed to produce and use power independently or in tandem with the larger grid.

Microgrids and traditional grids have similar components. Both rely on electricity production and send that energy where it is needed, also known as a load. Both ensure a match between energy production and the amount of energy needed. Microgrids are used for many reasons, including grid independence, security from natural disasters, or simply lowering community energy costs.

Microgrids can utilize some of the best clean technology by incorporating batteries, solar panels, wind turbines, geothermal technology, heat pumps, electric vehicles, and smart appliances to increase their efficiency.

Natural Disaster Relief

With the increase in natural disasters, energy security – not just at the national level but also at the local level – has become increasingly important. Microgrids offer energy security during outages.

A great example of microgrid innovation is a partnership between Alliant Energy and the village of Boaz in Richland County. This project demonstrates a simple microgrid, called a community microgrid, that provides energy to the 200 residents during grid power outages. Depending on its size and capacity, the microgrid can serve a community’s emergency response centers, water and wastewater treatment plants, grocery stores, fueling stations, government buildings, shelters, and sometimes the residents’ homes.

The $3 million project in Boaz includes a 400-kilowatt (kW) lithium iron phosphate battery connected to the community’s main distribution line. It supplies enough power for up to eight hours in the event of a grid outage. This setup provides critical power to residents and allows Alliant Energy the necessary time to resolve issues without causing community members to experience a critical loss of energy service.

Critical Infrastructure Support

Uninterruptible power is essential in health care, so reliable and sustainable energy solutions are paramount. Bellin and Gundersen Health Systems – soon to be Emplify—and Xcel Energy have announced a new microgrid project that will create one of the first fully resilient, renewable energy-powered health care campuses in the United States. The project, set to be completed in 2026, offers an example of how complex a microgrid can be.

This microgrid, being built at the Onalaska campus in La Crosse County, is considered a campus microgrid. A campus microgrid serves multiple buildings within a single company or organization. The microgrid will utilize a new battery energy storage system, the campus’s existing rooftop solar, and biogas energy from the La Crosse County landfill. It is expected to manage about 4.5 million kW of power per year, which is about the annual energy use of 411 homes.

This microgrid will allow one of Bellin and Gundersen Health System’s largest campuses to continue operating and providing essential care to the surrounding communities even during a power outage.

Remote Community Energy Supply

Microgrids can also provide critical infrastructure even in the most remote and cold places. The Alaska villages of Shungnak and Kobuk, located within the Arctic Circle, are not connected to the power grid and have relied on three diesel generators for power. Today, they are using a newly constructed hybrid microgrid.

Hybrid microgrids generate power using two or more locally sourced energy sources, such as wind and solar and include a battery for energy storage. These systems can connect to the main grid or operate independently (islanded), providing flexible and reliable power. The microgrid in Shungnak and Kobuk utilizes 233-kW of solar, 384 kilowatt hours (kWh) of battery storage, the three existing diesel generators, and a control system designed and managed by Ageto Energy.

The microgrid has saved these communities and their 450 residents over $200,000 in annual fuel costs while also protecting them from the fluctuations of the diesel market.

Vehicle-to-Grid Mobile Microgrids

As electric vehicles become more prevalent, a new technology known as “vehicle-to-grid” is emerging. This technology allows electric vehicles to serve as mobile power sources for the grid. Originally developed as “vehicle-to-load” to power devices directly, vehicle-to-grid technology extends this capability by enabling electric vehicles to supply electricity back to the grid, effectively turning them into mobile microgrids. A few utilities around the country have started to explore this technology in pilot programs.

Since December 2020, five electric school buses from Lion Electric in White Plains, New York, have been providing power back to the grid when they are not transporting students. This typically occurs during weekends, holidays and summer months, coinciding with peak electrical demand on the grid. With supportive policies and proper charging infrastructure, this same concept could expand to residential owners and commercial fleets, transforming electric vehicles from electricity consumers into valuable contributors to energy resilience.

Conclusion

Microgrids offer communities a way to lower energy costs, supply energy to critical infrastructure, and increase grid resilience. They promote beneficial partnerships between energy providers and the companies and communities they serve. In this way, microgrids offer a glimpse into how clean technology, if implemented properly, can provide cost savings, energy independence, and a healthy environment that can benefit the grid as a whole.
