§ Mr. Woof
asked the Secretary of State for Energy what was the total amount of sales of electricity by the public supply system for the years 1970, 1971, 1972, 1973, 1974 and 1975, respectively; and what proportion has been used by the iron and steel industry, other industries and in the domestic sector over the same period.
§ Mr. John Smith
Information on total oil stocks held at public supply power stations in the United Kingdom is not readily available. For Great Britain, the stocks of fuel oil held at main oil burning station, i.e. the bulk of the oil stocks held, are published in Table 17 of the Department of Energy's publication "Energy Trends", copies of which are available in the Library of the House. The latest figure, which will be published in the March issue of "Energy Trends", relates to the end of February when the stocks held were 0.96 million tons. Because of the Boards' integrated system and the flexibility this gives for switching generation between coal and oil 387W stations, to give the number of days consumption of oil in stock would be misleading.
