Turbine Specifications
Listed below are the official statistics and performance data for the the Endurance S250 that is recorded at our Test Facility in Spanish Forks, Utah.
- Total data set for these production statistics are 1,777 hours of 1-minute averaged wind speed and power.
- 1,100 hours above cut in wind speed of 8.9 mph.
- Average of 92 hours in each 1 m/s bin with a minimum of 71 hours in each 1 m/s bin up to 15 m/s.
- Density corrected with an average test site air density of 1.043 kg/m^3 (15% lower than standard sea-level).
- Peak binned power of 5.021 kW at 14 m/s.
- Power measured at the grid tie location (i.e. includes line losses and any controller parasitic losses).
