Scotland Dam, Connecticut
Because the station’s existing propeller turbine could not keep up with changes in the water level, the efficiency of the station decreased and the annual output suffered. The Barber propeller turbine was replaced with a new vertical Kaplan, double regulated turbine. The new Kaplan runner has a diameter of 106.3 in., 2000 mm. This new Kaplan turbine provided greater control to better deal with the changing water levels. Allowing the station to operate at a higher efficiency. And enabled them to generate at times where before, because of the propeller turbine, they were not able to. Norcan’s scope of work included, engineering, project management, manufacturing of the runners and wicket gates, dismantling, installation, and commissioning. Norcan provides innovative turbine solutions.
