Abstract
This study evaluates and analyses the performance of Ibom Power Plant from 2014 to 2016
based on performance indices such as capacity factor, load factor, plant capacity, utilization
factor, overall efficiency, and thermal efficiency. The operating margin which is the emission
factor (CO2 emission factor) that refers to the group of existing power plants whose current
electricity generation would be affected by the proposed clean development mechanism
(CDM) project activity was also determined. Data obtained from the Power Plant inventory
records and fault logbook includes monthly energy generation and number of failures for the
period under study. Results obtained from the analysis showed that the average capacity factor
was 28.89%, the typical load factor as calculated was 88.23%; plant capacity was estimated
to be 1,673,160MWH and the average generating capacity from plant records was
483,333.84MWH. The averages of the overall and thermal efficiencies were 27.37% and
27.92% respectively. Using the CO2 emission factor of 56 KgCO2/GJ, the weighted operating
margin emission factor (EFOM,y1-y3) was determined to be 26.17 KgCO2 /MWH and this was
attributed to increase in economic activities in Akwa Ibom State. Low plant availability as a
result of breakdown or failures, disruption of gas supply and other such factors were identified
among other reasons as key issues responsible for the power plant’s low performance.
