Most modern wind turbines are designed to generate utility compatible AC electric power. The easiest way to use these wind turbines for irrigation pumping is by intertying with the electric utility grid. However, because irrigation pumping requires large amounts of power during critical crop growth stages and minimum power during the nongrowing season, utilities have to supply power during peak load times and purchase power during off peak times. Five wind turbines having induction generators have been operated in water pumping experiments at Bushland, Texas. These turbines ranged in rated capacity from 25 to 100 kW and have included both horizontal and vertical-axis types. All units have operated at least 5000 hr, with one unit having been operated for over 20,000 hr. Performance curves, monthly energy production, percentage of run-time, and availability are given for each turbine.
