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
