Wind farm developer Ecogen of Cornwall plans to branch out from wind into another renewable -- energy from forest wastes. The company hopes to build a 10 MW power station in Kielder Forest to burn the tree-tops and twigs that are left to rot after logging has taken place. The power station, which would have a 40 metre chimney as well as cooling towers, would also be able to burn coppiced wood. One of the potential sites for its forest waste plant is close to Ecogen's planned 250 turbine wind farm at Humble Hill. This would enable the use of the same transmission link to the local grid network.
