The Butter Solar Portfolio – Wisconsin

J. Ranck Electric (JRE) was contracted by the RECON Corp. for the electrical work at three ground-mounted solar arrays in Wisconsin. In total, the Butter Solar Portfolio consists of 23 MW of solar power generated at 10 different solar sites located throughout Wisconsin, Iowa, and Minnesota. The multi-state power purchase agreement, and operated by BluEarth Renewables, is generating power which will be used locally by the Upper Midwest Municipal Energy Group and its customers.

JRE’s contract included the installation of AC and DC electrical work for 10.5 MW at the Arcadia, Cumberland, and Fennimore arrays in Wisconsin. JRE installed inverters, transformers/AC combiners, equipment pads, and racks, underground and above ground collection systems. JRE also installed the raceways and cabling for the DAS/SCADA/Met Station for the arrays communications. All commissioning, start-up, synchronization, and performance testing on the electrical and communication systems installed was also conducted by JRE. At the time of completion in the fall of 2019, Arcadia was the largest array in the state of Wisconsin.
