Our older drainage pumps require 25Hz power. The modern standard is 60Hz. Turbine 4, Turbine 5 and our EMDs (back-up generators) generate 25Hz power. We also have Frequency Changers that convert 60Hz power provided by Entergy to 25Hz. The graphic below shows how much 25Hz power we can currently generate with the sources available.
