Wisconsin Energy Corporation was incorporated in the state of Wisconsin in 1981 and became a diversified holding company in 1986. In the following year, several new subsidiaries including Wispark, Wisvest and Witech were established.
In 1994, WEC bought Lake Geneva-based Wisconsin Southern Gas and merged it into Wisconsin Natural. In the following year, Wisconsin Natural was merged with Wisconsin Electric.
The company acquired Eselco, parent company of Edison Sault Electric in 1998. Wisconsin Gas also entered the water utility business in 1998. Two years later, WICOR, a Milwaukee-based holding company of Wisconsin Gas, was acquired by WEC and the company became the largest electric and natural gas provider in Wisconsin.
WE Power was formed in 2001 to design, construct, own, finance and lease the new generating capacity included in WEC’s Power the Future strategy. In the following year, Wisconsin Electric and Wisconsin Gas began doing business under the trade name, WE Energies. The company received approval from the Public Service Commission of Wisconsin (PSCW) to begin construction on two natural-gas-fueled and two coal-fueled generating plants in 2003.
As a part of the company’s strategy to divest its non-core businesses, WEC sold WICOR Industries, a manufacturer of water systems, filtration and pool equipment, to Pentair in 2004.
We Energies announced an agreement to purchase the development rights for two, 80-megawatt wind farm projects from Navitas Energy, a wind development company in 2005. The agreement is part of the company’s commitment to derive 5% of its retail energy sales from renewable resources. In March 2006, We Energies filed a Certificate of Public Convenience and Necessity application with the PSCW for authorization to construct the Blue Sky Green Field Wind Project, which is being designed to generate up to 203 megawatts of electricity.
