Post-Reform Evaluation of the Transmission Sub-System of the Nigerian Electricity Value-Chain (original) (raw)

This paper provides a post-deregulation performance assessment of the transmission infrastructure of the Nigerian electric power grid using nine years performance profile of eight primary lines of the transmission subsystem. Performances of the lines for the six earliest postderegulation years are evaluated on a three-year basis, taking their performances for the three-year period that immediately preceded the deregulation as a baseline for comparison. Failure counts and outage durations per each line, in the two three-year post-reform periods, are compared to what was obtained in the baseline period. The results obtained show that the deregulation has not yielded significant improvement in the reliability of the transmission network. This indicates that better attention is needed to be given to the transmission assets being at the heart of the power system. Like the privatized assets of the industry, the state-owned Transmission Company of Nigeria must also be properly attended to in order to achieve sustainable development in the Nigerian electric power sector.
