Both transactions accelerate Duke Energy's continued growth in renewable energy.
"Today's announcement strengthens our commitment to investing in wind energy beyond 2008," said Wouter van Kempen, president of Duke Energy Generation Services (DEGS), a business unit of Duke Energy that owns and develops renewable energy assets.
Duke Energy will begin building the Campbell Hill Windpower project near Casper, Wyo., early next year. The facility's 66 wind turbines will begin generating electricity by late 2009.
PacifiCorp, which operates as Rocky Mountain Power in Wyoming, has entered into a 20-year agreement to purchase all of the power generated by the Campbell Hill project. The output from the project will go into the utility's integrated electric system, serving customers in Wyoming, Utah, Idaho, Oregon, Washington and California.
Separately, Duke Energy executed an agreement to purchase the General Electric wind turbines for its 2010 wind power generation projects.
"Soaring interest in wind energy has translated into growing demand for turbines and a tightening supply," said David Marks, DEGS senior vice president for wind energy.
"Securing wind turbines in a very competitive environment provides Duke Energy with the resources it needs to fulfill our commitment to clean, renewable energy."
By the end of 2008, Duke Energy will have more than 500 megawatts of wind-powered generation projects in operation and an additional 5,000 megawatts in development.
"The execution of power purchase agreements and the acquisition of cutting-edge technology are two of the key ingredients needed to commercialize our portfolio of development projects," said Marks. "We're on the way to making that vision a reality."
Terms of the two contracts were not disclosed.
Duke Energy's previously announced acquisition of Catamount Energy is expected to close later this month. The Catamount acquisition includes 300 megawatts of renewable energy in operation, including an interest in the Sweetwater project in Nolan County, Texas - one of the largest wind projects in the world. Duke Energy will also gain approximately 1,750 megawatts of development interests in several U.S. states and the U.K. through that acquisition.
"We're excited as we prepare to close the Catamount acquisition and continue to develop a strong portfolio of wind energy assets," said van Kempen.
Duke Energy Generation Services (DEGS) develops, owns and operates electric generation for large energy consumers, municipalities, utilities and industrial facilities.
DEGS specializes in developing innovative and environmentally sound generation solutions using a variety of fuels, including wind and other renewable energy sources.
