Evaluation of a Nigerian power plant for sustainable delivery

The overwhelming objective of the electricity power policy strategy is to ensure that Nigerian has an electricity supply market that can meet the needs of its citizens. This paper evaluates challenges, prospects and performance of Olorunsogo Power Plant in Nigeria. Questionnaire was administered and oral interviews conducted among experts and staffers of the power plant. Responses on the challenges and prospects were analysed using descriptive statistics while performance was analysed using established thermal efficiency, overall efficiency and reliability models. Results generally showed that major challenge (60%) lied on the shortage of gases, and the power plant had highest sustainability prospects (60%). Performance results revealed that the average overall efficiency, thermal and reliability in the five-year span were 29.0%, 29.6% and 85.6% respectively. The outcomes were below the international best practices of 60%, 75% and 98%, respectively. Hence, continuing improvement in plant performance becomes necessary.
