The Badger Hollow Solar Farm is a 300 MW solar photovoltaic energy station in Iowa County in southwestern, Wisconsin. Ownership is shared between Wisconsin Public Service Corporation (WPS), Madison Gas and Electric (MG&E), and Wisconsin Electric Power Company (WE Energies), with each utility owning 100 MW. It was the second utility-scale solar plant approved and constructed in Wisconsin.

Contents

The sites covers approximately 3500 acres, with between 2000 and 2200 acres used directly for the solar panel arrays. [1] The facility is located in the Village of Cobb and in the towns of Mifflin, Eden, and Linden. [2] It is located just south of Cobb and southeast of the nearby Montfort Wind Farm.

On April 18, 2019, WPS and MG&E purchased and acquired 150 MW of the Badger Hollow solar farm and the electrical tie in line for approximately $389.7 million. This purchase also included the acquisition of the 150 MW Two Creeks Solar Park. The total cost for this agreement was $1,299 per KW, or $194.8 million for the Badger Hollow component. [3] In March, 2020, WE Energies and MG&E purchased and acquired the remaining 150 MW of the solar farm for approximately $194.9 million. [4]

As part of project application materials, the facility was expected to require 17 full-time staff once constructed. The facility is eligible for the Federal Solar Investment Tax Credit (ITC). MG&E assumed that the facility would receive 30% of the ITC. The ITC would be normalized over the 30 year life of the project as required by the IRS.

Background

Through an executive order, Governor Tony Evers charged the Office of Sustainability and Clean Energy to achieve a goal that all electricity consumed in Wisconsin by 2050 be 100% carbon-free. [5] According to analysis conducted by the International Panel on Climate Change, the lifecycle emissions of electricity generated by utility-scale solar facilities is 48 gCO2eq/kWh (median value). [6] [7] By comparison, lifecycle emissions from electricity generated from coal and natural gas (combined-cycle plants) are 820 and 490 gCO2eq/kWh, respectively. [8]

The procurement and construction of utility-scale solar has also been justified by some in Wisconsin due to electrical generation supply concerns when several large coal-fired plants in the state will be closed in the early 2020s. Those coal-fired plant closures have since been delayed to the mid 2020s with major utility companies citing electricity reliability concerns and the delay in constructing new grid-scale solar. [9]

History

Badger Hollow Solar Farm, LLC, an affiliate of Invenergy, LLC, submitted a Certificate of Public Convenience and Necessity (CPCN) application to the Public Services Commission of Wisconsin (PSC) on June 1, 2018. [10] On April 18, 2019, the CPCN application to construct the facility was approved by the PSC. [2] In its approval ruling, the PSC found that the project satisfied the requirements of Wisconsin Statute § 1.12 and 196.025(1), known as the Energy Priorities Law. [11]

Major components of Badger Hollow include the PV panels, power conversion units (PCUs), collection lines, a collector substation, and an operations and maintenance (O&M) building. [2]

Construction of Badger Hollow Phase I started in 2020 and finished in November 2021. The project was delayed to allow the developer more time in managing the acquisition of the solar panels which was impacted by federal government changes to trade tariffs. [12]

A 5.7 mile, 138 kV generator tie line was constructed to connect Badger Hollow facility with the existing electric transmission system. [13] The tie line cost $15.6 million and finished full construction in December 2021. [14]

Construction of Badger Hollow Phase 2 (remaining 150 MW) faced time delays and cost overruns due to impacts from COVID-19 as well as US government trade and tariff investigations into solar panel distributors and compliance on the sourcing of materials and labor to produce the panels. [15] [16] Phase 2 entered full operation in December 2023. [17] [18]

Electricity production

In 2023, Badger Hollow I and II generated 176 GWh combined, approximately 0.28% of the total electric power generated in Wisconsin (63,216 GWh) for that year. [19] The facility had an approximate annual capacity factor of 13.2% in 2023. While presiding over the transfer of ownership stage, the PSC asked the owners to use an 18% capacity factor for their Electric Generation Expansion Analysis System (EGEAS) analysis. [20]

Solar Energy Generating Systems (SEGS) is a concentrated solar power plant in California, United States. With the combined capacity from three separate locations at 354 megawatt (MW), it was once the world's second largest solar thermal energy generating facility, until the commissioning of the even larger Ivanpah facility in 2014. It consisted of nine solar power plants in California's Mojave Desert, where insolation is among the best available in the United States.

Solar power has been growing rapidly in the U.S. state of California because of high insolation, community support, declining solar costs, and a renewable portfolio standard which requires that 60% of California's electricity come from renewable resources by 2030, with 100% by 2045. Much of this is expected to come from solar power via photovoltaic facilities or concentrated solar power facilities.

The energy sector in Hawaii has rapidly adopted solar power due to the high costs of electricity, and good solar resources, and has one of the highest per capita rates of solar power in the United States. Hawaii's imported energy costs, mostly for imported petroleum and coal, are three to four times higher than the mainland, so Hawaii has motivation to become one of the highest users of solar energy. Hawaii was the first state in the United States to reach grid parity for photovoltaics. Its tropical location provides abundant ambient energy.

Solar power in Florida has been increasing, as the cost of solar power systems using photovoltaics (PV) has decreased in recent years. Florida has low electricity costs compared with other states, which makes individual solar investment less attractive. Florida ranks ninth nationally in solar resource strength according to the National Renewable Energy Laboratory and tenth in solar generation by the Solar Energy Industries Association.

Solar power in Massachusetts has been increasing rapidly, due to Section 1603 grants for installations that began before December 31, 2011, and the sale of SRECs for $0.30/kWh, which allows payback for the system within 5 or 6 years, and generates income for the life of the system. For systems installed after December 31, 2011, and before December 31, 2016, the 30% tax grant becomes a 30% tax credit. There has been an appeal to the Congress to extend the 1603 program, the grant program, for an additional year.
