CAMPAIGNERS want Huntingdonshire to lead the way with a green electricity scheme that would harness the energy of the River Great Ouse. They have calculated that the river could produce 20-30 megaWatts a year, approximately sufficient for the needs of a town the size of Huntingdon. A series of run-of-river turbines could be installed at weirs along the Great Ouse, feeding into the National Grid at Little Barford power station in St Neots. The idea for hydro-electric generation, which is not just for fast-flowing rivers in mountainous terrain, could unlock the kinetic energy in any navigable river with little impact on the environment, according to Bev Gray, chairman of a campaign group opposing a wind farm in Huntingdonshire. He is urging Cambridgeshire County Council to commission a feasibility study into capturing the river's potential. But the Environment Agency, which is responsible for the river, is sceptical though stopped short of ruling out the possibility.
