The imagination of the Spanish press was caught last month by an engineering company's announcement that it had developed new wind energy technology which would go down in history as the country's most important contribution to the alternative energy industry to date. Baptised Ingecon W and developed by Ingeteam, the system is claimed to increase a wind turbine's power production by 5-10% at certain wind speeds, stabilise grid input and extend turbine life. According to Ingeteam's Gregorio Rivas, widely quoted in Spanish newspapers, Ingecon W basically consists of a generator and control system which allows turbines to work at variable rotational speeds, produce "synchronous" current and cuts the wear and tear on turbine machinery. It has been successfully tested in two Gamesa Eolica 500 kW turbines at the El Perdon farm in Navarra. Ingeteam now has plans for series manufacture of the Ingecon W which, it claims, Danish technicians from Vestas have been most impressed by.
