§ Mr. Leadbitterasked the Secretary of State for Energy what proportion of energy supply was produced by each type of power station for each of the past 10 years; and what are the proportions estimated for the future, taking into account new power stations under construction when they are ready for production.
§ Mr. EadieThe percentages of electricity supplied by different types of power station in the CEGB system during the past 10 years are as follows:
requirements in the 1980s having regard to North Sea oil production, the development of the Selby coalfield and the future of the coal industry.
§ Mr. VarleyMy Department maintains a set of forecasts of power station requirements. These projections take account of a variety of assumptions, including the availability of coal and oil supplies.
§ Mr. Leadbitterasked the Secretary of State for Energy what was the energy 523W generated by the Central Electricity Generating Board's stations in each of the past 10 years, and what growth rate in supply was achieved in these years.
§ Mr. EadieThe amounts of electricity generated and supplied by CEGB stations in the financial years 1964–65 to 1972–73 are quoted below from the CEGB Annual Report 1972–73, Volume 2. For 1973–74 the figures are provisionally estimated.
Electricity produced, TWh (Not weather-corrected) Year Generated supplied Annual percentage charge of electricity supplied 1964–65 151,301 141,022 +6.8 1965–66 160,360 148,820 +5.5 1966–67 164,885 152,772 +2.7 1967–68 175,705 162,693 +6.5 1968–69 187,064 173,418 +6.6 1969–70 195,093 180,719 +4.2 1970–71 201,164 186,158 +3.0 1971–72 205,673 190,525 +2.3 1972–73 220,603 204,497 +7.3 1973–74 (provisional) 217,000 201,100 -1.7
§ Mr. Leadbitterasked the Secretary of State for Energy what estimates of load growth in energy supply were made by the Central Electricity Generating Board during each of the past 10 years.
§ Mr. VarleyThe growth of load on the Central Electricity Generating Board system is forecast by the industry and published by the Electricity Council each year. The following table gives the estimated unit requirements on the Central Electricity Generating Board, assuming average weather conditions, for the year in which the forecast was made and the forecasts for the sixth year ahead. Unit requirements include sales to consumers and units used in transmission and distribution.
TWh (Terawatt hour) Year Weather-corrected outturn 6th year Ahead Forecast Percentage increase 1963–64 132 232 76 1964–65 142 238 68 1965–66 150 247 65 1966–67 156 238 53 1967–68 163 240 47 1968–69 174 250 44 1969–70 184 268 46 1970–71 191 272 42 1971–72 197 275 40 1972–73 208 286 38 If load growth experienced before the fuel emergency of last winter had continued, the comparable figure for 1973-74 would be about 219 TWh, 294 TWh and 34 per cent.
