Abstract: The Cornell Hydro in Northern Wisconsin was torn down, rebuilt, re-equipped and put into profitable operation. After extensive structural modifications to the old plant, three new 10,000 kw horizontal shaft tube turbines are now housed in a semi-outdoor type single-story structure. The structure also contains a conventional vertical shaft 800 kw generating unit. In the search for economy, the turbines were stripped down of the usual control equipment, consisting simply of a fixed blade wheel and a shaft rotating inside a steel conduit. The overall project cost $16,000,000 or $520 per kw of installed capacity.
