A marine current power installation that takes energy from marine currents. The marine current power installation takes kinetic energy of flow from the marine current and converts the kinetic energy into electrical energy. The marine current water power installation is used below the water level, for example, more than 50 m below the water level. The power installation can make a relatively large amount of power available even when the flow speed of the marine current is relatively low, for example, in the region of 1.5 m/sec or less. The water power installation has a water wheel or a rotor (turbine or propeller) which is of a diameter of, for example, 10 m or more, preferably between 30 m and 120 m.
