HC Deb 10 February 1953 vol 511 cc210-1
29. Mr. Nabarro

asked the Secretary of State for Scotland the anticipated load factor of the hydro-electric works embodied in the Breadalbane project No. 25 Constructional Scheme, capacity installed 88.5 megawatts, referred to in the North of Scotland Hydro-Electric Board (Constructional Scheme No. 25) Confirmation Order, 1953; and the anticipated coal economy equivalent based on that load factor and a conversion rate of 1.31 lb. of coal per unit of electricity generated, generally in accord with the average conversion rate of British Electricity Authority power stations in 1952.

Mr. J. Stuart

I am informed by the North of Scotland Hydro-Electric Board that the expected load factor of hydroelectric works embodied in the Breadalbane project will be approximately 40 per cent.; and that the expected saving in coal at a conversion figure of 1.31 lb. per unit of electricity generated will be about 180,000 tons annually.

30. Mr. Nabarro

asked the Secretary of State for Scotland the cost, £/per megawatt installed, respectively, including and excluding capital costs in respect of distribution facilities, for the 88.5 megawatts installed capacity of the hydroelectric works embodied in the Breadalbane project No. 25 Constructional Scheme, referred to in the North of Scotland Hydro-Electric Board (Constructional Scheme No. 25) Confirmation Order, 1953.

Mr. J. Stuart

I am informed by the Hydro-Electric Board that the estimated capital cost per megawatt to be installed is about £170,000, or if the cost of transmitting the power to the Board's grid is added about £180,000.

31. Mr. Nabarro

asked the Secretary of State for Scotland the anticipated dates of commencement and completion for the hydro-electrc works embodied in the Breadalbane project No. 25 Constructional Scheme referred to in the North of Scotland Hydro-Electric Board (Constructional Scheme No.25) Confirmation Order, 1953; and the aggregate consumption of cement, bricks, steel, cast-iron, and timber for all the works described in the Explanatory Memorandum, Command Paper No. 8740.

Mr. J. Stuart

I am informed by the Board that they hope to start construction of the Scheme this year, and to produce electricity from it in about four years' time. The Scheme should be substantially completed in five to seven years' time. The Board estimate that the Scheme will require 120,000 tons of cement, 12,000 tons of steel and 800 standards of timber. Use of bricks and cast-iron will be negligible.
