Minwind III-IX CEG designed the interconnection substation and collection feeders for this 11.5 MW wind farm located in Rock County, MN. The 161 kV substation included a high side switch and fuse and a 34.5 kV recloser on the low side of the substation transformer. It was designed with ease of installation and low up-front costs in mind. The project included material specification, detailed steel and foundation designs, and coordination of settings with the transmission utility. CEG also designed and specified equipment for the 3 miles of underground 34.5 kV collection feeders. Westridge and Christoffer Substations These substations are 10 MVA wind farm interconnections that tap into Xcel Energy and Great River Energy. Includes 69kV transmission lines in Jackson County, MN.
