Open Square generates electricity with its two hydro-electric turbines, and generators. This video below shows the start-up procedure for the “D” wheel, which involves regulating the flow of water entering the turbines, and stabilizing the electricity generated. Thereafter, the wheels are placed “on line” by connecting to the power grid. Shortly after this video was recorded, the start-up and shut-down procedure was converted to full automation. The process is now be monitored and controlled remotely.
