Emiyamrew Minaye ^[2] | Worknesh Hailu

Abstract: Generation system reliability is an important factor in the long term planning for future capacity expansion of systems to make sure that the total installed capacity is sufficient to support demand for new customers. The planning process utilizes reliability indices as criteria to decide on new investments in new generation capacities. Due to the high rate electricity demand of the country, stable and continuous supply of electrical power required to the consumers. Hence, improvement of the operational performance of a nations electric supply is vital for its socioeconomic developments. Gilgel Gibe I and Gilgel Gibe II hydropower generation systems are part of grid systems and supplies power for the entire Consumers in the country. Numerical and analytical methods are used to assess and evaluate the reliability, availability and performance index parameters.
