Dutch-Indo wind turbine manufacturer and developer, DAS Lagerwey of Pondicherry, plans to commission 20 MW by September and another 25 MW by March next year. The company has a 600 acre site at Kannankulam and a 400 acre site "a little further north" says managing director VR Ragunathan. A centralised control system is to be set up for the two wind farms. The company has six clients so far each planning to install 10-15 MW and has been measuring the wind in Kerala and Nagarcoil in Tamil Nadu. Tests of the Lagerwey 80 kW turbine in India, where three were installed in 1994, have shown it is good for areas with periods of low winds, such as Tirunelvelli. The company is installing six further 80 kW turbines, three for a customer and three of its own at Nagarcoil. All nine units have been supported by the Indian Renewable Energy Development Agency. "We are forming a team with our clients. We give performance guarantees on power production -- if the power generated is less than we had predicted, we pay compensation. If it is better, we gain. All our clients are willing to share this bonus clause," says Ragunathan. The company is planning to import four of Lagerwey's new 750 kW by the end of the year. There are also plans for a wind-diesel version of the 80 kW.
