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.
