HC Deb 23 November 1981 vol 13 c277W
31. Mr. Spriggs

asked the Secretary of State for Energy whether there are any possible sources of water power which could be used for the specific purpose of generating electric power for the whole of Great Britain.

Mr. Mellor

The potential for additional economic electricity generation from water power is kept under study by the generating boards and my Department, but is unlikely to provide more than a small proportion of electricity requirements before the end of the century.
