Abstract: This paper describes the results of enhancing energy efficiency of hydro turbines by implementing the energy conservation measures for hydro turbine generators. The procedure for evaluating the on-line performance of generators is discussed. The energy saving in generators by maintaining optimum generator terminal voltage, by reducing the stator winding temperature by improving the performance of coolers and reducing the excitation loss by appropriate tuning of excitation system are enumerated in details with case studies. The implementation of energy conservation measures have a techno-economic feasibility with a payback period of 1 to 5 years.
