Planning Permission

Key features of a small hydro scheme include:

• a hydraulic 'head' - vertical distance from water source to the turbine.
• a water intake above a weir or behind a dam
• a pipe or channel to take water to the turbine
• a turbine, generator and electrical connection
• an outflow, where the water returns to the watercourse

These elements raise a number of important planning issues and planning permission will usually be needed.
