Independent experts are investigating the causes of a fire on a Vestas turbine at Nissan's new wind farm at its car manufacturing plant in Washington, Tyne and Wear in north-east England. The fire broke out just before Christmas in the nacelle on the second-hand turbine, one of six bought from a wind farm in Germany. The turbines had just completed their commission phase. The affected turbine has been dismantled for examination. Meantime, the remaining machines are shut down pending the results of the investigation. Although the wind farm was built and commissioned without participation from Vestas, the manufacturer is involved in the investigation. Ironically, Nissan's £2 million wind farm was picked out by the Department of Trade and Industry (DTI) as one of ten best green energy projects to start generating in 2005. The projects were chosen because they are exciting and innovative, help reduce greenhouse gas emissions and raise awareness of renewable energy. Three other wind projects were chosen by the DTI: the 90 MW £105 million Kentish Flats offshore wind farm, the 97 MW Black Law wind farm in Scotland -- the UK's largest -- and the 58 MW Cefn Croes wind farm.
