CapX2020 project begins
The CapX2020 utilities have started construction on the estimated $500 million, 150-mile Hampton-Rochester-La Crosse 345 kilovolt project. The first segment under construction is the 16-mile 161 kV line between a new north Rochester substation near Pine Island and the existing Northern Hills Substation in northwest Rochester.
According to Xcel Energy, the CapX2020 transmission lines will provide reliable and affordable electricity service to customers in Minnesota and the surrounding region, while also expanding access to renewable energy.
The Minnesota portion of the Hampton-Rochester-La Crosse project is 345 kV double-circuit capable, which allows for future capacity expansion on the existing structures. To reduce land impacts, single-pole steel structures predominantly will be used. The poles are spaced about five per mile.
Foundation work on the 45-mile, 345 kV segment between the north Rochester substation and the Mississippi River is scheduled to start in August. Construction in Wisconsin will start in 2014 with an in-service date of 2015 for the entire project.
