§ Mr. J. H. Osbornasked the Minister of Power (1) on the assumption that the average cost of coal supplied by the National Coal Board to the Central Electricity Generating Board is 3d. per therm, what estimate he has made of the generating cost of electricity per unit, based on generating costs for the most advanced coal-fired power stations in the country and on the fact that the power station is sited near the pithead;
(2) on the assumption that the average cost of coal supplied by the National Coal Board to the Central Electricity Generating Board is 4d. per therm, what estimate he has made of the generating cost of electricity per unit, based on generating costs for the most advanced coal-fired power stations in the country and on the fact that the power station is sited near the pithead:
(3) on the assumption that the average cost of coal supplied by the National Coal Board to the Central Electricity Generating Board is 5d. per therm, what estimate he has made of the generating cost of electricity per unit, based on generating costs for the most advanced coal-fired power stations in the country and on the fact that the power station is sited near the pithead;
(4) on the assumption that the average cost of coal supplied by the National Coal Board to the Central Electricity Generating Board is 6d. per therm, what estimate he has made of the generating cost of electricity per unit, based on generating costs for the most advanced coal-fired power stations in the country and on the fact that the power station is sited near the pithead.
§ Mr. MarshI am advised by the C.E.G.B. that the estimated base load generation cost per kWh of the most advanced coal-fired power station would be 0.55d., 0.65d., 0.74d. and 0.83d. with respective pithead coal prices of 3d., 4d., 5d, and 6d.
