PORTLAND, Ore. (AP) -- Utility company Portland General Electric Co. said Thursday it will buy 141 turbines from Siemens Power Generation Inc. to finish construction of its 25,000-acre Biglow Canyon wind farm.
Financial details were not disclosed.
Siemens Power Generation, a division of Germany-based Siemens AG, has installed about 7,000 turbines at some of the world's largest wind farms, Portland General said.
Portland General is building the project in three phases. The first phase, with 76 turbines, became operational in December. Phase two's 65 turbines are expected to be installed in 2009 and the third phase's 76 turbines will be installed in 2010.
When complete, the wind farm is expected to have an installed capacity of nearly 450 megawatts, enough to power more than 100,000 homes, the company said.
Portland General said it expects total project costs for phases two and three of the project to remain within its previously projected range of $700 million to $800 million.
Portland General shares fell 5 cents to $22.92 in morning trading, while Siemens' U.S.-traded shares fell $1.86 to $110.50.
