Turbines and Towers in Sagebrush Country
127 wind turbine generators, spanning across 9,000 acres near Ellensburg, Washington.
Towers are 221 ft higher at hub, 13.2 ft wide base and 7.six ft wide at prime and weigh 104 tons. Every single turbine consists of 3-blades, 129 ft extended, 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 V80-1.8 MW machines manufactured by Vestas, a Danish company. Every generator can generate 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 totally extended is 351 ft and total weight is roughly 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 takes an typical of 100 to 260 cubic yards of concrete. Every single 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.five rpm, turning clockwise (front view) with a rotor diameter of 264 ft, larger 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.

Each and every turbine is capable of making 1.8 megawatts, or a total of 229 megawatts of capacity, sufficient electricity to serve about 73,000 homes when all 127 are creating at complete capacity.
