As part of the Severn Embryonic Technology Scheme (SETS) proposal, the Severn Tidal Fence Consortium (STFC) has studied the technical feasibility of an innovative approach to extracting energy from the tides. The STFC have proposed the use of a ‘tidal fence system’ as a method of extracting tidal power from the Severn Estuary whilst minimizing impact to the natural environment and shipping and importantly not impeding future commercial shipping developments.
