asked the Secretary of State for Energy whether the price of fuel oil supplied to the Central Electricity Generating Board has risen as fast as the price of crude oil since 1973; what is the current average works cost of generation per ton of (a) oil fuel and (b) coal and coke supplied to power stations in Great Britain engaged in public supply, what increases are in the pipeline; and what is the corresponding cost per useful therm.
Figures published in Tables 88 and 99 of the Digest of United Kingdom Energy Statistics 1979 show the movements in the average price of oil for burning by the public electricity supply industry in Great Britain and the average value per tonne of crude oil imported into the United Kingdom from all sources between 1973 and 1978, the last year for which the comparison is available. The relevant figures are:
|Oil for burning used by ESI (Great Britain)||United Kingdom crude oil imports|
|Coal-fired stations||Oil-fired stations|
|Total inclusive fuel costs||1·0796||1·1253|
|Operation, maintenance and insurances||0·1195||0·0887|
|Total generation costs||1·2919||1·3135|
