HC Deb 27 July 1959 vol 610 c9W
Mr. Moss

asked the Paymaster-General the latest figure of capital costs per kilowatt of electricity produced at electricity power stations using coal, and at nuclear power stations.

Mr. Maudling

For the large stations now being built in this country the cost per kilowatt of output capacity is approximately £120 to £130 for nuclear stations, excluding the initial fuel charge, and £40 to £50 for coal-fired stations.

A conventional station is of course between two and three times more expensive to run than a nuclear station.
