Visit to C.H. Corn Power Plant February 1, 2007 Located 20 miles southwest of Tallahassee at southern tip of Lake Talquin One of only two hydroelectric plants in state of Florida

Visit to C.H. Corn Power Plant Three turbines – one Kaplan and two propeller Maximum power generation of 12 MW Typical power output is about 3 MW 12 MW is about 3% of Tallahassee’s typical power need of 425 MW

Visit to C.H. Corn Power Plant Built in 1929 by West Florida Power Company Abandoned as a power plant in 1970 Refurbished in 1981 by City of Tallahassee as a hydroelectric demonstration project Became fully operational in 1985 under City of Tallahassee Electric Utility Services
