§ Mr. Simon ThomasTo ask the Secretary of State for Wales what percentage of Welsh electricity supply was provided by nuclear power stations for each of the last 10 years. [137217]
§ Mrs. LiddellI have been asked to reply.
365WThe electricity supply in Wales is mainly provided through the national grid and it is not possible to distinguish separately the source of the electricity.
Electricity produced by the one nuclear station in Wales (Wylfa) (the second station, Trawsfynydd, closed in 1993) may be consumed in England while nuclear electricity generated in England, Scotland or France can be consumed in Wales. In 1999 Wylfa's output to the national grid was 7.2 TWh while electricity consumption in Wales is estimated to have been 16 and 17 TWh.
