There are four Francis turbines for flow rates of ( ever? ) 60 m³ / s on the right side ( Liginiac ) and another for a flow rate of 190 m³ / s on the left side ( Saint- Pierre ). Is operated by the Société hydroélectrique du Midi ( SHEM ). The maximum capacity of the hydropower plant is 128 megawatts or 146 according to several sources.
