Duke Energy Completes 200-MW Wind Project in Wyoming

LCG, October 13, 2010--Duke Energy announced recently that its 200-MW, Top of the World Windpower Project is now connected to the grid and generating power. Duke announced the project in August 2009.

Duke Energy executed a 20-year, power purchase agreement (PPA) with Pacificorp for the electricity generated from the Top of the World Windpower Project, located near Casper, Wyoming. Siemens supplied 44 wind turbines, and General Electric supplied 66 turbines.

Duke has rapidly expanded its wind turbine capacity, which now totals 935 MW in North America. Later this year, Duke's Kit Carson Windpower Project in eastern Colorado is scheduled to commence operations and add 51 MW of electric generating capacity.

Duke initially built its wind portfolio through acquisitions of wind developers, acquiring Tierra Energy's Wind Development Business in 2007 and Catamount Energy Corporation in 2008. Duke Energy stated that it has committed over $1 billion since 2007 to grow its wind power business.
