This paper studied the operation of Selorejo Hydro Power. The study was conducted at Wonorejo Hydro Power, East Java Province Indonesia. Water resources development in Indonesia was targeted to supply water needs. The important aspect of water resources developments used for hydro electrical power. Water use for hydro electrical power gave more advantage because it would decrease the use of gasoline. Restriction of surface water resources and higher cost of hydraulic structures intensify the need for an optimum capacity and operation for reservoir system. Thus, it was needed to allocate the water use as efficient as possible. To reach this target, it was needed to make a system model for optimization. Optimization analysis would give more information for allocating water of each objective function. Optimization of hydro electrical energy was carried out for yearly reservoir. Selorejo reservoir is yearly reservoir was the reservoir which could reserve water during the rainy season than it was used in the dry season. For this kind of reservoir, inflow was not the same as outflow. The methodology consisted of optimization energy which was due to turbine discharge and head of hydro electrical power. Linear Programming was used as analysis of optimization for making decision. Linear programming was very important as the basic of developing operation research. It was known as a deterministic tool because all parameters used in this program was determined certainty. In fact, there was never seen certainty case. Results can use as the pattern of rule curve as the basic of reservoir operation. The rule curve considered optimization discharge, head and energy of hydro electrical power, spillway out flow and storage of reservoir. © Research India Publications.
