HC Deb 22 November 1979 vol 974 cc325-6W
Mr. Hooley

asked the Secretary of State for Energy how much additional installed nuclear electricity generating capacity came on stream in each year from 1969 to 1979; and how much is estimated to come on stream from 1980 to 1990.

Mr. Norman Lamont

The additional nuclear generating capacity commissioned by the Central Electricity Generating Board since 1969 is as follows:

1971 645 MW
1973 195 MW
1976 400 MW
1978 400 MW

During the period 1980–1990 it is estimated that around a further 5,000 MW of AGR capacity will be commissioned. Further capacity will depend inter alia on progress made with the PWR. It is the CEGB's intention to order a PWR, subject to all Government consents and safety clearances being obtained.

Power stations in Scotland are a matter for my right hon. Friend the Secretary of State for Scotland.

Mr. Hooley

asked the Secretary of State for Energy what calculations have been made of the cost per unit of electricity generated by the existing advanced gas-cooled reactor stations.

Mr. Norman Lamont

One CEGB AGR station was operating in 1978–79 one reactor for the whole year, the other for approximately six months. Both reactors have still to reach full output potential. I am advised by the CFGB that the cost of generating electricity from that AGR station in 1978–79 on the basis of calculation employed for other types of station was about 1.3p/Kwh.

Power stations in Scotland are the responsibility of my right hon. Friend the Secretary of State for Scotland.

Mr. Hooley

asked the Secretary of State for Energy how many of the existing Magnox nuclear power stations it is estimated will be still in use in the year 2000.

Mr. Norman Lamont

The Central Electricity Generating Board envisages that none of its existing Magnox nuclear power stations will still be in use in the year 2000.

Power stations in Scotland are a matter for my right hon. Friend the Secretary of State for Scotland.

Mr. Hooley

asked the Secretary of State for Energy what is the amount of energy supplied by all nuclear power stations in the United Kingdom, in terms of million tons of coal equivalent, during the past 12 months.

Mr. Norman Lamont

Information on energy supplied by all nuclear power stations in the United Kingdom in terms of millions of tonnes of coal equivalent is published in the Department's monthly statistical bulletinEnergy Trends. In the 12 months ending September 1979, the latest 12-monthly period for which information is available, this amounted to 13.4 million tonnes of coal equivalent.
