Turbines and Towers in Sagebrush Country
127 wind turbine generators, spanning across 9,000 acres close to Ellensburg, Washington.
Towers are 221 ft high at hub, 13.two ft wide base and 7.6 ft wide at leading and weigh 104 tons. Each turbine consists of three-blades, 129 ft lengthy, 11.62 ft at widest and 1.six ft at tip with every single blade weighing 14,300 lbs. The rotor (blades, hub and nose cone) weighs 42 tons.
Turbine generators are V80-1.8 MW machines manufactured by Vestas, a Danish company. Each generator can create 690 volts, which is stepped-up to 34,500 volts by an on-board transformer. The generator is housed inside a fiberglass nacelle.
The generator and nacelle with each other weigh 69 tons.
Total height with a blade fully extended is 351 ft and total weight is approximately 270 tons. These are the biggest wind turbine generators in Washington State (as of 2007)
Each and every tower foundation reaches a minimum depth of 25 ft and a maximum of 32 ft based on bedrock depth and takes an typical of 100 to 260 cubic yards of concrete. Every single foundation calls for 120 anchor bolts that span from the surface of the ground to the bottom of the foundation. A single 28 ft anchor bolt weighs approximately 150 lbs.
Rotors turn 15.five rpm, turning clockwise (front view) with a rotor diameter of 264 ft, bigger than a wingspan of a Boeing 747.
Turbines can generate electrical energy at wind speeds as low as 9 mph, reaching their peak of production at 31 mph and shut down at constant wind speeds of 56 mph. The prevailing winds are from the northwest.
Each turbine is capable of creating 1.eight megawatts, or a total of 229 megawatts of capacity, sufficient electrical energy to serve approximately 73,000 residences when all 127 are producing at full capacity.

Total height with a blade totally extended is 351 ft and total weight is roughly 270 tons. These are the largest wind turbine generators in Washington State (as of 2007)
Each tower foundation reaches a minimum depth of 25 ft and a maximum of 32 ft depending on bedrock depth and requires an average of one hundred to 260 cubic yards of concrete. Each foundation calls for 120 anchor bolts that span from the surface of the ground to the bottom of the foundation. A single 28 ft anchor bolt weighs approximately 150 lbs.
Rotors turn 15.five rpm, turning clockwise (front view) with a rotor diameter of 264 ft, larger than a wingspan of a Boeing 747.
