§ Mr. Gerry Fowlerasked the Secretary of State for Energy whether the four flow exhaust turbines of the type being installed at Littlebrooke power station represent a capital cost saving over a six flow exhaust machine of the type installed at Drax A.
§ Mr. BennFour-flow exhaust turbines would normally be cheaper than six-flow machines of equivalent capacity, but the choice between different types of turbine depends on many factors in addition to initial capital costs. I am, however, asking the chairman of the generating board to write to the hon. Member with further information about this matter.
§ Mr. Gerry Fowlerasked the Secretary of State for Energy when the first four 23W flow exhaust turbines of the type being installed at Littlebrooke power station were purchased in the United Kingdom; and how many have been sold abroad.
§ Mr. BennThe first 660 MW four flow exhaust turbine of the type subsequently provided for Littlebrooke D was ordered in June 1973. Six machines of this type have been sold abroad.
