摘要：Due to the benefit of the vital nature of electric power, both to our economic, personal well-being and other purposes, a power system is expected to supply electrical energy as economical as possible and with a high degree of quality and reliability. A reliable power station is one which would supply the required power within its installed capacity at any time within the specified voltage and frequency limits. Essential for this evaluation are the station's installed capacity and available generation. This work is to assess the past data for performance of some power stations in Nigeria from 2006 to 2017 to determine if they are supplying electric energy within their installed capacities in line with energy global best practices. The combined installed capacity of these power plant is 37% of the twenty-one thermal power plants connected to the national power grid. A historical operational data of these selected plants over a period of twelve years was obtained and evaluated based on power plant performance indices analytical techniques. Results obtained from these analysis shows that, the equivalent availability factor which is accepted as the relative index of equipment reliability in this study, for Afam I-V, Afam VI, Delta and Egbin are (17.13, 78.57, 34.42, & 70.17) percent accordingly. It also shows that Afam VI and Egbin power stations have a good workable preventive maintenance programmes that upholds availability of their generators whereas, Afam I-V and Delta power stations were always faced with corrective maintenance.
