Wild Horse Wind & Solar Facility

Operated by Puget Sound Energy, Wild Horse produces 273 MW from 149 turbines and features a 500 kW solar array. Located on the arid shrub-steppe ridges of central Washington, the mixed wind-solar facility illustrates renewable integration across energy systems and grid resilience. Turbines are Vestas V80 units, approximately 221 ft hub height with 264 ft rotors. Subsurface engineering includes foundations, turbine base access, gearboxes, and interconnections. The modern visitor centre hosts displays on turbine mechanics, electrical conversion and regulatory engineering, solar-photovoltaic integration, and habitat stewardship.

Open seasonally (April 1–Oct 31), 09:00–17:00 daily. Self-guided exhibits and outdoor trails are free. Guided 60-minute turbine/solar tours run daily at 10:00 and 14:00, no booking required. The 0.5-mile trail includes gravel paths requiring closed-toe shoes; vehicle access to turbine base can be arranged for mobility needs. A 45–60 minute educational presentation is available by appointment. Conference facilities are also bookable. Visitors should bring weather-appropriate clothing and complete a liability form (on-site). The facility is accessible by car; Kittitas County Scenic WA Trail leads on campus.
