The aims of the project were: (i) to demonstrate radio control of a control valve at a lake reservoir remote from the penstock intake and the provision of power to operate the control valve; (ii) to demonstrate flow control management by using storage from one catchment area to complement the variable flow in the second catchment area; (iii) to demonstrate the optimisation of turbine efficiencies by giving priority to more efficient nozzles. The operation of the lake valve is computer controlled; however there were faults in the system which were causing the battery to discharge. These faults took some time to rectify and when they were eventually rectified it was found that the flow through the valve was not sufficient and a larger valve with a better intake structure had to be installed. The project has not interfered with the amenity value of the area and has provided substantial supplementary income to two farmers in the locality and is producing electricity economically from a renewable source.
