Utility Scale Renewable Resources
PSE Wind Projects
Wild Horse:
229 MW
32% capacity factor
Kittitas County, WA
9000-acre footprint
127 Vestas V80 wind turbines
Klondike III:
223.6 MW Facility50 MW PSE share
80 GE 1.5 MW, 44 Siemens 2.3 MW, 1 MHI 2.4 MW
Owned/operated by PPM Energy
Hopkins Ridge:
150 MW
35% capacity factor
Columbia County, WA
11,000 acre footprint
83 Vestas V80 wind turbines
1.8 MW Capacity
220 feet tall at hub
350 feet to tip of blade
Wild Horse Solar Demonstration ProjectLocated at Wild Horse Wind Farm near Ellensburg, WA
First utility-scale wind-solar facility in nation
Excellent sun - same solar resource as Houston
Already disturbed land
Existing transmission and operational synergies
Added tax benefits from co-location
500 kW Project – 300 homes at peak
Largest in the Pacific Northwest by a factor of three
~5 Acre footprint
$4-5 million in capital costs
90% of facility now operational;
final completion spring 2008
Primary Solar Site – Former quarry, too high for wind turbines (FAA airspace concerns)
Wind Farm Layout – 127 Turbines
