About this plant
The Wild Horse Wind Farm is a 273-megawatt wind farm that generates energy for Puget Sound Energy that consists of one hundred twenty seven 1.8-megawatt Vestas V80 turbines and twenty two 2.0-megawatt Vestas V80 turbines on a 10,800-acre (4,400 ha) site in Kittitas County, Washington, 17 miles (27 km) east of Ellensburg, Washington. The turbines are placed on the high open Shrub-steppe ridge tops of Whiskey Dick Mountain, which was chosen for its energetic wind resource, remote location, and access to nearby power transmission lines. The towers are 221 feet (67 m) tall, and each blade is 129 feet (39 m) long, with a total rotor diameter of 264 feet (80 m), larger than the wingspan of a Boeing 747. The turbines can begin producing electricity with wind speeds as low as 9 mph (14 km/h) and reach full production at 31 mph (50 km/h). They shut down at sustained wind speeds of 56 mph (90 km/h). The site is also home to one of the largest solar array (500 kW) in Washington.
