Turbines and Towers in Sagebrush Country
127 wind turbine generators, spanning across 9,000 acres close to Ellensburg, Washington.
Towers are 221 ft higher at hub, 13.2 ft wide base and 7.6 ft wide at leading and weigh 104 tons. Every single turbine consists of three-blades, 129 ft long, 11.62 ft at widest and 1.6 ft at tip with each and every blade weighing 14,300 lbs. The rotor (blades, hub and nose cone) weighs 42 tons.
Turbine generators are V80-1.eight MW machines manufactured by Vestas, a Danish business. Every single generator can produce 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 collectively weigh 69 tons.
Total height with a blade fully extended is 351 ft and total weight is around 270 tons. These are the largest 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 requires an average of 100 to 260 cubic yards of concrete. Every single foundation requires 120 anchor bolts that span from the surface of the ground to the bottom of the foundation. A single 28 ft anchor bolt weighs around 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.
Turbines can make electricity at wind speeds as low as 9 mph, reaching their peak of production at 31 mph and shut down at continuous wind speeds of 56 mph. The prevailing winds are from the northwest.
Every turbine is capable of producing 1.eight megawatts, or a total of 229 megawatts of capacity, adequate electricity to serve approximately 73,000 homes when all 127 are producing at full capacity.

The generator and nacelle with each other weigh 69 tons.
Total height with a blade fully extended is 351 ft and total weight is roughly 270 tons. These are the largest wind turbine generators in Washington State (as of 2007)
Every tower foundation reaches a minimum depth of 25 ft and a maximum of 32 ft depending on bedrock depth and takes an typical of 100 to 260 cubic yards of concrete. Every single foundation needs 120 anchor bolts that span from the surface of the ground to the bottom of the foundation. A single 28 ft anchor bolt weighs around 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.
Turbines can create electrical energy at wind speeds as low as 9 mph, reaching their peak of production at 31 mph and shut down at continuous wind speeds of 56 mph. The prevailing winds are from the northwest.
Every turbine is capable of generating 1.8 megawatts, or a total of 229 megawatts of capacity, adequate electrical energy to serve around 73,000 residences when all 127 are generating at complete capacity.
