AN AUSTRALIAN SCHEME

The Barren Jack (sometimes, called Burrenjuck) hydro-electric scheme, which was recently placed in commission, is a New South Wales State Government undertaking. It utilises a portion of the outflow from a dam built on the Murrumbidgee River for irrigation purposes and the initial installation of generating plant consists ot two vertical turbo sets, each of 5,000 k.w. capacity at 80 per cent, power factor. The turbines are of Francis type, operating at 333 revs, per min., and the generators are of the salientpole type. Current is generated at 6,600 volts 50 cycles, and stepped up to 66,000 volts for transmission. The ultimate capacity of the Barren Jack scheme will be 20,000 k.w., and the capital cost will then be £1,000,000, or the equivalent of,-say, £5 per k.w. in annual charges. Eventually another hydro-electric development, known as the Shoalhaven, will bo undertaken, and will provide the southern portion of New South Wales with a further 50,000 k.w. also, the Hume Dam, now being built on the Murray River, will yield a further 60.000 k.w. The last hydro-electric source to be utilised ,in this district will bo the Snowy 'River, which can be harnessed to give an output of 300,000 k.w'.
