Dane County and Madison Gas and Electric (MGE) are joining forces to construct a solar power plant on County-owned land that will supply clean electricity for one customer only: Dane County. The solar array, expected to total eight megawatts of capacity, will be situated on a 41-acre parcel at the north end of Dane County Regional Airport. MGE will own the array, which will be interconnected directly to the utility’s distribution system nearby.

This project invites superlatives. When completed, it will be the largest solar power plant in Dane County, more than three times as large as Epic Systems’ 2.2 MW installation serving its Verona headquarters, and four times as large as Madison College’s 1.8 MW rooftop array at its Truax campus, which is expected to start generating electricity in November.

Thanks to its Renewable Energy Rider service, MGE has the capability of supplying commercial customers to clean electricity generated from new, offsite solar installations. Through this service, customers like Dane County can lock in a dedicated source of solar at a fixed price for up to 20 years. The cost of building a Renewable Energy Rider project would be borne exclusively by the customer or customers purchasing the electricity.  Other nonparticipating customers would be unaffected by the transaction.

In this case, MGE will recover the full cost of building the airport installation from Dane County’s energy purchases. The county has a goal to source 100% of the electricity it consumes from renewable resources. The output from the airport project should total about 25% of the County’s annual electrical usage.

Later this fall, MGE will select a general contractor to design and build this installation. The utility will also file an application for permission to supply Dane County with the project’s output. The Public Service Commission will review the terms of the agreement to ensure that the airport array is cost-neutral from the standpoint of the utility’s other customers.

Dane County and MGE jointly unveiled its partnership at an October 1st press conference at the airport. The announcement also coincided with the unveiling of the County Executive’s proposed budget for 2019, containing a number of provisions to advance the County’s development and use of renewable energy. One of them involves Lake Farm Park, home of Lussier Family Heritage Center and numerous campsites. The proposed budget allocates $435,000 to build enough solar capacity to supply 100% of the electricity and hot water used at the park.

“Dane County is a nationally-recognized leader in renewable energy adoption and innovation. From the hardest-working landfill in the state, to what will be one of the largest solar farms in the state, I’m proud of the progress we’ve made,” said Dane County Executive Joe Parisi. “This historic solar farm will help increase local clean energy jobs, reduce carbon emissions, and reduce the tax burden on Dane County residents through lower energy bills.”

“MGE welcomes the opportunity to partner at the County’s request on this solar project and supports its efforts to achieve 100% renewable energy for its facilities,” said MGE Chairman, President and CEO Jeff Keebler.

If approved, construction of the project is expected to begin in 2019. For more information on the project see: https://www.countyofdane.com/press/details.aspx?id=4370
