HC Deb 22 February 1968 vol 759 cc187-90W
Mr. J. H. Osborn

asked the Minister of Power (1) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell one million tons in a year of opal suitable for use in a power station to one or more outside customers at 3¾per therm; and what effect this will have on the unit cost of electricity to existing consumers;

(2) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell 10 million tons in a year of coal suitable for use in a power station to one or more outside customers at 3½d. per therm; and what effect this will have on the unit cost of electricity to existing consumers;

(3) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell 5 million tons in a year of coal suitable for use in a power station to one or more outside customers at 3½d. per therm; and what effect this will have on the unit cost of electricity to existing consumers;

(4) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell one million tons in a year of coal suitable for use in a power station to one or more outside customers at 3½d. per therm; and what effect this will have on the unit cost of electricity to existing consumers;

(6) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell five million tons in a year of coal suitable for use in a power station to one or more outside customers at 3¼d. per therm: and what effect this will have on the unit cost of electricity to existing consumers;

(7) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell one million tons in a year of coal suitable for use in a power station to one or more outside customers at 3¼d. per therm; and what effect this will have on the unit cost of electricity to existing consumers;

(9) what estimate he has made, based on current rates of consumption, of the consequent increase on the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell five million tons in a year of coal suitable for use in a power station to one or more outside customers at 3d. per therm; and what effect this will have on the unit cost of electricity to existing consumers;

(10) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell one million tons in a year of coal suitable for use in a power station to one or more outside customers at 3d. per therm; and what effect this will have on the unit cost of electricity to existing consumers:

(11) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell 10 million tons in a year of coal suitable for use in a power station to one or more outside customers at 4d. per therm; and what effect this will have on the unit cost of electricity to existing consumers;

(12) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell five million tons in a year of coal suitable for use in a power station to one or more outside customers at 4d. per therm; and what effect this will have on the unit cost of electricity to existing consumers;

(14) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board if the National Coal Board sell 10 million tons in a year of coal suitable for use in a power station to one or more outside customers at 3¾d. per therm; and what effect this will have on the unit cost of electricity to existing consumers;

(15) what estimate he has made, based on current rates of consumption, of the consequent increase in the total annual cost to the Central Electricity Generating Board of coal supplied by the National Coal Board, if the National Coal Board sell five million tons in a year of coal suitable for use in a power station to one or more outside customers at 3¾d. per therm; and what effect this will have on the unit cost of electricity to existing consumers.

Mr. Marsh

The cost to the Central Electricity Generating Board would depend on the price of the fuel used to make up their requirements and on whether the price of other coal they used was affected.
