SPX Transformer Solutions Delivers Large Power Transformer to North Rochester Substation in Minnesota

Moving a large transformer between Waukesha, Wisconsin and Pine Island, Minnesota was no small order: It required a train, a 385-foot trailer and three, 600-horse-power trucks.

The transformer departed from SPX Transformer Solutions’ facility in Waukesha by rail car, arriving in Randolph, Minnesota, where a specialized transportation company loaded the transformer onto a trailer and, using three trucks— one pulling, two pushing— started the gargantuan power transformer on its 40-mile journey to Pine Island. The SPX transformer, which weighed 542,000 pounds, took up two lanes of traffic and required a police escort in the overnight and early morning hours.

The transformer successfully arrived at Xcel Energy’s new North Rochester Substation in early February and is now part of the CapX2020 Hampton-Rochester-La Crosse project.

CapX2020 is a joint initiative of 11 transmission-owning utilities in Minnesota, North Dakota, South Dakota, and Wisconsin, which was formed to upgrade and expand the electric transmission grid to better ensure continued reliable and affordable electric service.

This project provides needed transmission capacity to support new power generation, including renewable energy. According to CapX2020, these lines are projected to cover more than 800 miles, making it the largest development of new transmission in the upper Midwest in nearly 40 years.

The North Rochester Substation is expected to be placed into service in May 2014, connecting a 161kV transmission line to the Rochester, Minnesota area, as well as a 345kV transmission line running between Hampton, Minnesota and Holmen, Wisconsin.
