The Cannelton Project is located on the Kentucky shore of the Cannelton Locks and Dam located on the Ohio River 721 miles below Pittsburgh, Pennsylvania. It is three miles upstream from Cannelton, Indiana. The navigation locks are located on the right descending bank or Indiana side of the river. The upper pool maintained above the dam extends upstream for a distance of 114 miles to the McAlpine Locks and Dam at mile 607 and for a short distance up the Salt River. The Powerhouse will enclose three horizontal-shaft bulb turbines with an expected running diameter of 7.5 meters. Each generator will produce approximately 28 MW at a 6.9 kV buss voltage for a total of 84 MW and 390,000 mwhs annually. Each generator buss will connect to the main step-up power transformers and then switch gear and take-off structure on top of the entrance building to the powerhouse and on to the 138kV transmission line. The transmission line will extend approximately 8.3 miles from the plant and will connect to a Louisville Gas and Electric substation.
