Less than ten months after its official opening the 47.5 MW Waardpolder wind farm in North Holland has been temporarily shut down for modifications and repair. During the refit program the nacelles from the 19 NedWind 250 kW turbines will be removed and the hoods fitted with rubber attachments in order to reduce noise levels while the yaw control brake units will be re-lined to further reduce noise. The early refit is due to noise pollution regulations which have prevented the plant operating at full capacity. On completion of the program, owner Dutch utility ENW hopes to reverse the present shortfall between actual and predicted output levels. A defective gearbox will also be replaced during the refit and measures will be taken to prevent further failures. With the turbines still under guarantee the cost of the program will be borne by Nedwind.
