Over the past few months, RENEW Wisconsin and our partners have been developing statewide policies that would expand customer access to community solar projects. The National Renewable Energy Laboratory defines community solar, also known as shared solar or solar gardens, as a distributed solar energy deployment model that allows customers to buy or lease part of a larger, offsite shared solar photovoltaic (PV) system. Community members subscribing to a solar facility receive credits for their share of the power produced, either in electricity bill savings or energy (kWh) credits.
New community solar projects are being rapidly developed around the country; 21 states, including Minnesota and Illinois, have already enacted policies that expand the community solar market between subscribing organizations and participating customers. Community solar deployment in the United States has achieved a five-year annual growth rate of 53%. But, lacking statewide policies to promote community solar options, Wisconsin is quickly falling behind.
Since 2010, the number of solar energy systems purchased by US homeowners and businesses has grown tenfold. By the end of 2019, nearly two million homeowners and businesses were reaping the rewards from producing solar-generated electricity. Solar power is popular with many US consumers, and it has become an affordable option for many households and businesses. Yet access to solar power is limited. More than 50% of Wisconsin households cannot access solar energy onsite because they rent, live in multi-tenant buildings, have roofs that cannot host a solar system, or experience some other constraining factor.
In Wisconsin right now, only regulated utilities and cooperatives can provide energy from solar gardens to customers. A few utilities, like Madison Gas and Electric, offer a shared solar service that customers can enroll in today. However, most Wisconsin utilities do not currently have a comparable program available for their customers. That lack of access will persist unless state lawmakers adopt a modernized policy to promote a robust community solar marketplace.
Senator Duey Stroebel (R – Saukville) and Representative Timothy Ramthun (R – Campbellsport) have introduced legislation that would expand access to community solar in Wisconsin. This legislation enables the development of more community solar and supports energy freedom, expands customer choice, saves money on your utility bill, all while creating healthier and more resilient communities.
With a stronger statewide community solar policy, we would open the door for homeowners, businesses, schools, churches, and nonprofits to supply themselves with clean, affordable electricity from a local solar array.
Community solar legislation would benefit all utility customers by adding locally generated electricity to our energy grid while strengthening the rural economy at the same time. Community solar brings guaranteed savings for every subscriber as well as predictable and stable long-term energy costs. It gives customers a choice to support local clean energy projects while expanding access to affordable renewable energy for low-to middle-income residents.
Community solar expansion would allow more Wisconsin farmers to lease their land to host solar arrays and receive a guaranteed secure income for 25 years or longer. This drought-resistant cash crop is especially valuable for Wisconsin’s agricultural communities facing economic stress.
The soil underneath the panels can be planted with a variety of native plants and perennials. In addition to minimizing agricultural runoff and fixing nutrients in the soil, these perennials create a high-quality habitat for bees, butterflies, and other insects that move pollen in and around the fields and improve farm productivity.
When solar panels have reached the end of their useful lives, the equipment can be removed, and crop production can resume on the land that has become more fertile as a result of the native plantings.
A robust community solar market in Wisconsin will create thousands of jobs, spur hundreds of millions of dollars in economic growth, and save customers millions in utility bills. Community solar is proven to support economic development, expand consumer choice and bring clean energy to urban and rural communities across Wisconsin.

 The Vision of US Community Solar: A Roadmap to 2030
When Governor Tony Evers introduced his 2021-23 Budget Bill in February, it included 28 provisions to advance clean energy and energy efficiency in Wisconsin. Among those provisions were recommendations to expand Focus on Energy, invest in the clean energy workforce, and support Wisconsin’s electric vehicle infrastructure.
Unfortunately, by the time the Governor signed the Budget on Thursday, July 8th, those 28 provisions, along with a majority of the Governor’s other initiatives, were removed from the Budget document adopted by the Joint Finance Committee (JFC) and legislature.
A number of the provisions and other clean energy bills may still be considered during the remainder of the upcoming regular legislative session. Among the proposals we expect to be considered include:
- Community Solar Expansion – Authorize the development of non-utility-owned community solar projects. Would direct the PSC to establish fair credit rates for subscribers and compensation to utilities for the use of their infrastructure and billing services. (Introduced for co-sponsorship on July 14th)
- 3rd Party Financing – Affirm 3rd party financing of solar arrays is legal.
- Direct Purchase of Automobiles – Enable electric vehicle manufacturers to sell vehicles directly to consumers in Wisconsin, either online or at manufacturer-owned facilities, without going through an independent dealership.
- EV Charging Station Grants – Allocate up to $10 million of the unspent VW Settlement funds for clean energy corridor incentives for EV charging stations.
- EV Charging Fees – Clarify selling electricity by the kilowatt-hour to EVs does not subject EV charging station owners to utility regulation.
RENEW Wisconsin will continue to work with the legislature and the Governor to advance these and other clean energy initiatives. We hope you will join us.

The proposed Koshkonong Solar Energy Center would be located in southeast Dane County upstream of the Rock River. The centerpiece would be a 300-megawatt solar power generation facility anticipated to begin producing energy in 2024. Koshkonong Solar will also include a 165-megawatt battery storage component to help bolster grid reliability.
As Wisconsin continues to retire coal-fired power plants it is vital to replace those fossil fuel electricity generators with emission-free renewable energy. For example, the Columbia Energy Center, located just south of Portage, is now slated for a 2024 retirement.
Koshkonong Solar Energy Center needs vocal public support to get approved and help shift Wisconsin to clean energy. Voice your support for local solar energy by submitting a short comment today to the Public Service Commission (PSC) of Wisconsin.
Project to be located in southeast Dane County
Koshkonong Solar would advance the clean energy goals of Dane County, its local municipalities, and residents, and the State of Wisconsin. Koshkonong Solar will generate enough emissions-free electricity to power 60,000 average American homes or just about ¼ of the 240,000 households in Dane County. The project also represents exactly ¼ of the amount of solar capacity Dane County called for in its Climate Action Plan. This single project would also bring an estimated $200 million of investment including lease payments to local landowners and new revenue streams to local governments. Local governments in the project area will receive $1.2 million per year for the life of the project based on Wisconsin’s utility aid fund formula.
The developer for this project is Invenergy, which has successfully permitted other large solar farms in Wisconsin (Badger Hollow, Paris). Koshkonong, like Invenergy’s other projects, is slated to be acquired by Wisconsin utilities, including Madison Gas and Electric.
Air Quality and Carbon Emission Reduction Benefits
Koshkonong Solar will reduce CO2 emissions by between 15 and 20 million tons over its 30-year life, along with reductions in other forms of air pollution such as 12,000 tons of nitrogen oxides (NOx), 12,000 tons of sulfur dioxide (SO2), and 804 tons of particulate matter (PM2.5).

The emissions reductions from the estimated 600,000 megawatt-hours of energy production for the project are equivalent to the carbon sequestered by 7 million tree seedlings grown for 10 years, or the avoided CO2 emissions from 2,345 railcars worth of coal burned. See other comparisons at the EPA greenhouse gas equivalency calculator.
Soil Retention and Water Quality Benefits
Koshkonong Solar will establish deep-rooted prairie vegetation amidst the arrays. This type of vegetation will increase infiltration of the site compared with current agricultural usage by (+2.2%), reduce stormwater runoff (-60% for a 1-year 24-hour rainfall event), nitrogen outflow (-48%), phosphorus outflow (-53%), and Total Suspended Solids outflow (-87%).
These upstream water quality improvements would have a positive impact on downstream environments, and yield material benefits for watershed ecosystems, human health, and recreation. Furthermore, the prairie vegetation will help turn atmospheric carbon into organic carbon, which will be deposited and build up the soil for future agriculture. Koshkonong Solar, like other solar farms, can be returned to agricultural use after the project is completed and equipment is removed, see our solar farm FAQ to learn more.

How much agricultural land would it take to power our state with solar energy? RENEW has calculated that it would take less than half a percent of Wisconsin’s total land to supply half our state’s electricity from solar. This is approximately the same amount that is currently in Wisconsin’s Conservation Reserve Program.
RENEW’s factsheet solar and agricultural land use.
Last week the Federal Energy Regulatory Commission (FERC) dismissed a challenge to state control of net metering. The unanimous decision made on Thursday, July 16, 2020 was great news for RENEW Wisconsin and our members. Homeowners, business and manufacturers that generate their own solar energy can now breathe easy, knowing that the oversight for net metering policy remains in the hands of Wisconsin’s own Public Service Commission.
The New England Ratepayers Association (“NERA”) had petitioned the FERC to take control over net metering policy for the entire country. If the petition were granted, states would have lost the ability to set policy on solar electricity generated by utility customers. The challenge to state control of net metering, the policy that enables energy producers to get bill credit for the extra energy they push back on to the grid, threatened the solar investments of thousands of families and businesses in Wisconsin.
RENEW joined dozens of other clean energy advocacy organizations in a petition to dismiss the issue and encouraged Wisconsin’s political leadership to get involved. Many elected officials from around the country joined in the fight to protect net metering including Wisconsin’s own, Attorney General Josh Kaul.
