How Does the Valmont Power Station Work?

The Valmont Power Station burns coal in a huge furnace called a boiler. The walls of the boiler are made of water pipes. The boiler heats the water in those pipes and turns it to steam. The steam drives a turbine which generates electricity. Then raw ditch water is used to cool the steam inside the pipes back to water. This condensing process creates a vacuum which pulls the steam through the turbine. The process takes place in a closed loop system which cycles continuously.

The three lakes which make up the Valmont Lakes complex are separated by dikes and connected by channels. Ditch water is pumped out of the lake on the right (Hillcrest), into the plant where it is used to re-condense steam running the turbines. This process transfers heat to the lake-water. The warm water is returned to the Leggett-Owens Lake (on the left), and cools off as it slowly circulates back to the south lake, where it begins the process again.
