Abstract: The large dams are built on big rivers with multi-purpose mostly power generation and water supply for irrigation and domestic water supply. In addition, water is to be released downstream to meet the agreement made with downstream users. The water from these reservoirs is mostly released through hydropower plants equipped with multi-unit turbines. The operation of no. of units depends on the load demand or the obligatory amount of water to be released. The output of turbine units depends on the discharge and head available. The turbines are designed for particular values of its parameters and give the best performance when operated about design values of these parameters. The proper selection of several units for meeting the required load demand saves water or obligatory release of water increase the generation from the plant. In this paper, the optimization approach has been presented to select the optimal number of turbine-generator (TG) units operation to enhance generation for obligatory release of water downstream. It is found that up to a 7% increase in generation is achieved from an existing multi unit plant using a developed method. This enhanced generation will reduce carbon footprint and generate additional funds for a sustainable environment
