Each spillway drives a Francis turbine supplied by Dominion Engineering of Canada. The turbines have a nominal speed of 136.4 rpm with a guaranteed maximum runaway speed of 252 rpm. The turbines have a rated output of 56,000 hp at a net head of 148 ft (13.7 m), which consume of water at full load. The runners weigh 28 tons and have a diameter of 12 ft 10 inches (1.2 m). The speed of the each turbine is controlled by a Woodward supplied governor located on the generator floor. The generating unit are located apart between centres. Each turbine is directly connected to a dedicated to a 44 pole 11 kV synchronous generator supplied by British Thomson-Houston (BTH). Each generator has an output of 44.44 MVA at a power factor of 0.9 and a total weight of 362 tons with the rotor weighing185 tons. The generators are each enclosed in thick-walled octagonal concrete housing, each with a makeup air intake located in each upstream corner. The generators are air cooled by fans on the top and bottom of the rotor circulating air, while water cooled radiators located each corner of the generator pit removed heat from the air.
