Turbines and Towers
127 wind turbine generators, spanning across 9,000 acres near Ellensburg, Washington.
Towers are 221 ft higher at hub, 13.two ft wide base and 7.six ft wide at leading and weigh 104 tons. Each turbine consists of 3-blades, 129 ft extended, 11.62 ft at widest and 1.6 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.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 together weigh 69 tons.
Total height with a blade fully extended is 351 ft and total weight is around 270 tons. These are the biggest 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 based on bedrock depth and takes an average of one hundred to 260 cubic yards of concrete. Each foundation demands 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 15.5 rpm, turning clockwise (front view) with a rotor diameter of 264 ft, bigger than a wingspan of a Boeing 747.
Turbines can generate 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 generating 1.8 megawatts, or a total of 229 megawatts of capacity, sufficient electricity to serve roughly 73,000 houses when all 127 are generating at complete capacity.

The generator and nacelle together weigh 69 tons.
Total height with a blade completely extended is 351 ft and total weight is about 270 tons. These are the biggest wind turbine generators in Washington State (as of 2007)
Every single tower foundation reaches a minimum depth of 25 ft and a maximum of 32 ft depending on bedrock depth and requires an typical of 100 to 260 cubic yards of concrete. Each and every 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 approximately 150 lbs.
Rotors turn 15.5 rpm, turning clockwise (front view) with a rotor diameter of 264 ft, bigger than a wingspan of a Boeing 747.
Turbines can create electricity at wind speeds as low as 9 mph, reaching their peak of production at 31 mph and shut down at continual wind speeds of 56 mph. The prevailing winds are from the northwest.
Each and every turbine is capable of producing 1.eight megawatts, or a total of 229 megawatts of capacity, sufficient electrical energy to serve around 73,000 residences when all 127 are producing at complete capacity.
