This time-lapse video shows the assembly of three wind-power turbines within a two-day period in June 2011 at Puget Sound Energy’s Lower Snake River Wind Project-Phase I, located in Garfield County, Washington. From the ground to the tip of a vertical blade, the 2.3-megawatt turbines stand more than 430 feet tall and weigh 340 tons. The boom on the crane erecting the turbines extends 390 feet into the air. When completed in early 2012, PSE’s newest wind farm will have 149 turbines capable of generating 343 megawatts of electricity, enough to serve 100,000 households.
