In 1938, hydro supplied 40% *;* -ef total power generated in central ate* ;"iioni; last year thli had fallen to .5 '->'36.5% (chart above). Load Increase* Because of rapid ''bad growth to 398.billion kwhr in .. 1951, construction of hydro plants j,/could not keep pace, so more and more of the total had to be supplied by Ijp'^itcsm: 393-billion kwhr compared to L^^jiW-bllUon by hydro. II fast load 'v .-/growth continues, hydro will supply an smaller part of the total. <(.4 Inslollad Capacity, At the end of v 1^32, installed hydro capacity had in* |creased to 31,630.000 hp. a gain of l$V .,1,900,000 hp over 1951 (chart). This *i|>ich rate of installation will probably ^continue tor the next ten yeare. By Out time, big developments on the Co ll**' *himbi River will have been pretty [r. .wellcompleted; Niagara Falls and the Lawrence River International Sec tion will have been developed. Then ^re will be few sites remaining for x :*hat we think of large hydro proj* so rate of growth must ease off. ' Fwblle Utilities. Particularly in the |*-> :^a**'btattern and western parts of the U, 8., public utilities arc assuming a larger part in hydro construction, a\ shown in the tables on following pages. Utilities are building IS projeet* with 300,000 hp total capacity in New Eng land and Middle Atlantic States, ten plants with over 1,000,000 hp total capacity in Pacific Northwest. By for the largest pert of total hydro capacity, however, is being built by federal and other government agencies. Since 1932 a total of 110 of such pro jects have been completed or are under construction, for an ultimate capacity of 27.000,000 hp. Of this, over 13.000.000 is in service and over 8,000,000 is on order. Pumped Storage. The world** larg est pumped-storage unit is being in stalled by TVA in its Hiwassee plant. The plant, originally designed (or two 80,000-hp units, had one unit installed in 1940. The second, a pump-turbine. Is now on order. For power generation, the unit will act as an BO.OOO.hp tur bine driving a 70,000-lcw generator. As a pumping unit, the generator will serve as a 102,000-hp motor to drive the turbine as a 3900-cfs pump. Conada. Water-power development in Canada during 1952 was at a record high with over 1,000,000 hp going into operation. This brings total capacity to 14,300.000 hp (chart), of which 90% is installed in central stations. These hydro plants produced over 96% of the total central-station power, which reoched nearly 60-billion kwhr. The Hydro-Electric Power Commis sion of Ontario pushed rapidly ahead with construction of its Sir Adam Beck-Nlogoro No. 3 development and is going to complete the entire project of 1,200.000 hp in twelve 100,000-hp units. Initial operation is scheduled for 1954. This year the Commission an nounced plana for a 225,000-hp pumped-storage plant to be built in the forebay of the generating plant. The Commission is also ready to start work on the St. Lawrence devel opment os soon es tome agency is given permission to build the U.S. section. This project will develop 2,200,000 hp, construction of which will probably start this year. Aluminum Co of Canada continues work on its Kemano project in north west British Coiumbio. This develop ment, second largest In the world, will supply power to the world's largest aluminum-refining plant. Hydro pro ject Is planned for sixteen 140,000-hp vertical 4-noisle impulse turbines to operate under 2S00-ft head. These units, largest to operate under to high a heed, will be housed In an under ground plant. POVrt .^h-imtMeci raja MOOtIN riANT SUBVfY
