HC Deb 07 March 1983 vol 38 cc274-5W
Mr. Best

asked the Secretary of State for Energy if he will give for each of the past three years for which figures are available, the number of units generated in Wales by (a) nuclear power stations, (b) coal power stations, (c) oil power stations and (d) hydroelectric and pump storage stations.

Mr. John Moore

I am advised by the CEGB that electricity supplied by generating stations in Wales for the past three financial years was as follows:

Electricity supplied GWh
Type of station 1979–80 1980–81 1981–82
Nuclear 8,088 7,036 8,917
Coal 8,915 9,234 11,007
Oil 7,114 4,468 3,632
Hydro-electric and pumped storage 566 579 575

Mr. Best

asked the Secretary of State for Energy if he will give for each of the last three years for which figures are available, the net annual inflow and outflow of power units between Wales and the rest of the United Kingdom.

Mr. John Moore

The CEGB's integrated power supply system for generation and bulk supply of electricity throughout England and Wales does not identify, as part of its regular measurements, inflows and outflows of electricity between Wales and the rest of the United Kingdom. It is therefore not possible to provide the figures in the form requested. However, it is estimated by my Department that for the years 1979, 1980 and 1981 there was a net outflow of electricity through the public supply system from Wales amounting to 10, 7 and 10 TWh respectively.
