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 PlantThree turbines – one

Kaplan and two propellerMaximum power

generation of 12 MWTypical power output is

about 3 MW12 MW is about 3% of

Tallahassee’s typical power need of 425 MW
