§ 86. Mr. Eadieasked the Minister of Power if he will give estimates of the costs of electricity sent out from Dungeness B, Hinckley Point B and Hunterston B nuclear power stations on the basis of a 20-year depreciation period, with interest during construction at 8 per cent. and including royalties payable to the United Kingdom Atomic Energy Authority.
§ Mr. MasonThe Central Electricity Generating Board's estimates of the costs at Dungeness "B" and Hinkley "B" on the basis of a 25-year life, with interest at 8 per cent. and including the royalty payable to the Atomic Energy Authority on AGR stations of 0014d. per unit, were given in the reply to my hon. Friend, the Member for Bassetlaw on 13th March.—[Vol. 779, c.355.] They are 0.56d. and 0.52d. per unit respectively. The Board no longer considers it appropriate to assume a 20-year life for AGR stations in comparing generating costs. The effect of assuming a 25-year life for the stations has been to reduce the cost per unit by about 0.03d. Questions relating to Hunterston "B" are for my right hon. Friend the Secretary of State for Scotland.
