Spring Lake Solar

OneEnergy is currently developing a 6MW solar energy project in the Town of Mukwonago, Waukesha County, Wisconsin.

Spring Lake Solar will be situated on about 28 acres of land and will produce electricity for local homes and businesses - enough to power 1,600 average Wisconsin homes per year. The project's expected useful life is 30-50 years, after which it will be fully removed. After the solar facilities are removed, the well-rested, nutrient-rich soils will be ready for farming.

Spring Lake Solar Project Overview

OneEnergy intends to start construction in the spring of 2027, pending receipt of all required permits/approvals and availability of key equipment. Construction is expected to take approximately 4-6 months. Once complete, the Project will generate clean power for local homes and businesses. The Project will produce enough electricity to power nearly 1,600 average Wisconsin homes, or power about 50 homes per acre.

OneEnergy will complete all environmental studies, surveys, and permits required by the County and State prior to commencement of construction, including the following: wetland delineation, Phase I Environmental Site Assessment, erosion/storm water/sediment control analysis, soil and geotechnical analysis, Wisconsin State Historic Preservation Office review, Wisconsin Department of Natural Resources (WDNR) endangered resources review, WDNR Construction Site Storm Water Runoff permit.

During peak construction, Spring Lake Solar will support more than 30 union jobs. OneEnergy prioritizes hiring construction jobs from within the state and will work with the community to enable as much local hiring as possible. Solar installer is one of the fastest jobs in the U.S. and is a family-supporting job. Wisconsin companies we have worked with in the past include Westphal & Co. (based in Madison), Pieper Power (based in New Berlin), and Arch Electric (based in Plymouth).

A 16-foot wide gravel access road will provide access to the site from County Highway I north of Section Road. The site wil be enclosed by an 8-foot tall woven-wire deer exclusion-style agricultural fence, similar to what you may see around an orchard, and benefits from existing treelines on all sides. To enhance the existing vegetative screening, we are proposing additional screening using native species in strategic locations. Spring Lake Solar will interconnect to the existing 3-phase electric distribution lines along County Highway I. The area beneath and around the panels will be pre-seeded with a cover crop prior to construction, and permanently planted to a low-growing perennial pollinator/prairie mix following construction. The project design preserves several mature oak trees on the land, and the property outside of the project area will continue to be in agricultural use.
