HC Deb 07 May 1991 vol 190 cc375-6W
Mr. Redmond

To ask the Secretary of State for Energy if he will list the number of power failures that have occurred in the Doncaster area during the past 12 months giving(a) location, (b) reason for breakdown and (c) the duration of the breakdown until supply was resumed; and what were the figures 12 months ago.

Mr. Heathcoat-Amory

Only supply interruptions of a major nature are required to be reported to the Secretary of State under regulation 35 of the Electricity Supply Regulations 1988. Essentially these interruptions involve 20 MW or more, or 5 MW for one hour or longer or more than 5,000 consumers for one hour or longer. During the past two years no such interruptions involving the Doncaster area have been reported by Yorkshire Electricity other than the blizzard of 8 and 9 December 1990 which affected major parts of Doncaster.
