§ Mr. Stainton
asked the Secretary of State for Energy what are his best available estimates of industry's standby generating capacity at the end of 1972, 1973, 1974 and now.
§ Mr. Eadie
I regret that reliable estimates of stand-by generation capacity within industry—that is, capacity available for use only during interruption or restriction of the public electricity supply—are not at present available. However, the Business Statistical Office is currently conducting an inquiry which will provide this information. Preliminary results are expected by the autumn and I shall write to the hon. Member giving details as soon as possible.
