Wind farm developer Trigen has revised its plans for a wind farm at Blaencorrwg in West Glamorgan, south Wales. Trigen, a consortium of British company Ecogen, SeaWest of California and Tomen of Japan, had its first application for 66 turbines refused by Port Talbot Borough Council -- against the recommendations of its own planning officers. Now the company has submitted a new application for 36, 500 kW turbines, larger machines than those in the earlier application. Ecogen's Tim Kirby says the revised layout and fewer turbines means the wind farm can hardly be seen from Glyncorrwg -- the nearest village and the source of most of the opposition. As well as submitting revised plans, Trigen has also lodged an appeal against the refusal of the earlier scheme. This approach, known as twin-tracking, is a common feature of the British planning system and helps minimise the time spent in bringing a project through the planning process.
