History
In 2005, Orion Energy announced plans to develop a 450-megawatt wind farm with 225 turbines at Biglow Canyon in the Columbia River Gorge, at the time the largest project of its kind in Oregon. Portland General Electric (PGE) acquired Orion’s development right to the $200 million project in 2006. In November 2006, PGE purchased the first 76 turbines for the project from Vestas, with the project cost increasing to an estimated $256 million for the first phase. PGE broke ground on the site in February 2007. In the middle of October 2007, ten Vestas V82 wind turbines were energized to produce the first electricity at Biglow. The last of the 76 turbines in the first-phase of the wind farm development became operational in December 2007.
The turbines for phase 2 and 3 were purchased from Siemens Energy. There will be 141 SWT-2.3-93 turbines, with a capacity of 2.3 MW each. Phase 2 of the project was completed in August 2009, adding 65 turbines to the wind farm. The expansion brought generating capacity to 275 megawatts. Phase 3 will add an additional 76 wind turbines, with the cost of phases two and three totaling $700 to $800 million. Phase 3 will complete the project and allow for a maximum generating capacity of 450 megawatts, though the anticipated generation is estimated to average 150 megawatts. The final phase was completed in September 2010, with the project totaling 217 turbines at a cost $1 billion.

Famous quotes containing the word history:
“What would we not give for some great poem to read now, which would be in harmony with the scenery,—for if men read aright, methinks they would never read anything but poems. No history nor philosophy can supply their place.”
—Henry David Thoreau (1817–1862)
“Let us not underrate the value of a fact; it will one day flower in a truth. It is astonishing how few facts of importance are added in a century to the natural history of any animal. The natural history of man himself is still being gradually written.”
—Henry David Thoreau (1817–1862)
“In every election in American history both parties have their clichés. The party that has the clichés that ring true wins.”
—Newt Gingrich (b. 1943)
