Dr. Michael Clark
asked the Secretary of State for Energy which sites, other than the Severn estuary, are being considered by his Department for tidal power generation.
Mr. David Hunt
The Department is giving 50 per cent. support to the Mersey Barrage company's current £800,000 study of a barrage in that estuary. Preliminary surveys of three possible small scale sites have been made by consultants and reports of these have been published and placed in the Library of the House. A further preliminary survey of all other feasible small scale sites on the west coast of the United Kingdom is in progress.
