Tennessee Valley Authority – Chickamauga

Ivyland, PA – American Governor Company (AGC) was selected recently by the Tennessee Valley Authority to design, manufacture, and install (4) 3-D Cam controls for the Chickamauga Hydro Plant, near Chattanooga, Tennessee. The station has 27MW Kaplan units, and retain the original Woodward Mechanical Cabinet Actuators. In the late 1990s, Woodward installed Summit 517 3-D Cam Blade controllers, but they had been increasingly problematic over the years and not supported by the OEM. Our project was for a surgical retrofit of the controller hardware only, retaining all the existing field devices. Imagine, as a Control Room Operator, going from a non-working, 2-line alpha numeric display, into a full color AGC Touchscreen HMI!

Chickamauga Dam is on the Tennessee River and was constructed in the late 1930s as part of a New Deal-era initiative to improve navigation and bring flood control and economic development to the Tennessee Valley. The dam impounds the 36,240-acre (14,670 ha) Chickamauga Lake and feeds into Nickajack Lake.
