To ask the Secretary of State for Energy if he will provide an itemised account, for the last financial year available, of Central Electricity Generating Board costs of generating electricity from nuclear fuel and coal, itemising fuel costs, capital charges, interest during construction, provision for decommissioning and all other costs, together with the total number of kWhs generated from each fuel, and calculate an average cost per kWh of each fuel.

The latest analysis of comparative generation costs made by the CEGB gave data for 1983–84. This included an assessment of all costs arising from the construction, operation and decommissioning of power stations, before, during and beyond their lifetime. For plant commissioned between 1965 and 1979 the resultant costs, expressed as an average over lifetime and adjusted to March 1987 prices, are as follows:

Fuel costs2·301·09
Capital charges (including interest during construction and decommissioning)0·481·55
Other costs0·240·40
Average cost per KWh3·023·04
Total electricity generated (GWh)175,11731,260
For the more modern plants at Hinkley Point B and the first stage of the coal-fired station at Drax the average cost on a comparable basis was 2·82 p/KWh and 3·03 p/KWh respectively.
