asked the Secretary of State for Energy what was the total amount of electricity generated in Wales in 1979; how much was generated by nuclear, coal and hydroelectric plants, respectively; what was the total consumed in Wales in 1979; and how these figures compare with those for 1967.

The total amount of electricity generated in Wales in 1979 compared with 1967 was as follows:

GWh
	1967	1979
Total electricity generated	14,716	29,770
Of which:
Coal fired plant*	11,258	10,885
Nuclear	2,612	9,461
Hydro	232	232
Pumped storage	408	322
* On a heat apportioned basis for mixed-fired stations.

Total sales to consumers in Wales in 1967 were 10,788 million KWh. The comparable figure for 1979 is not yet available. In 1978 total generation was 26,494 GWh with total sales to consumers in Wales, of 13,229 million GWh.
