Charlotte-based SPX will enlarge and improve its Waukesha Electric Systems' manufacturing facility in Waukesha, Wis., with an investment of approximately $70 million. The resulting building and infrastructure enhancements are expected to double the facility size. The company manufactures large, high-voltage power transformers that are utilized by electric utilities, independent power producers and independent transmission operators.

In late 2009, Waukesha Electric Systems was awarded a $10.7 million grant by the U.S. Department of Energy to help enhance the flexibility and reliability of the nation's power grid by developing and manufacturing a smaller, more efficient superconducting transformer for electric utilities. "Waukesha Electric Systems has been involved in the development of high temperature superconducting (HTS) transformer technology for over a decade under the auspices of various DOE programs," said Lee Powell, SPX segment president.

This DOE grant is part of a larger program to demonstrate advanced Smart Grid technologies and integrated systems to help build a smarter, more efficient, more resilient electrical grid. Working with fellow grant participants including the University of Houston, SuperPower and Oak Ridge National Laboratories, Waukesha Electric Systems plans to develop, build, test and install a new superconducting transformer in Southern California Edison's Smart Grid by the end of 2013.
