| Abstract | City Power’s Engineering Operations performance targets have traditionally been informed through benchmarking with overseas utilities, but this approach to target setting has proven to be inadequate. An alternative approach was therefore considered whereby the performance targets are based on the operationally achievable performance levels of the network, subject to the existing characteristics of the infrastructure and its operations. Eskom Distribution developed a simplified reliability modelling approach to inform the designed performance level of their networks. This approach was used and applied on the City Power networks. Where necessary, the initial Eskom approach was customised in order to accommodate the differing standard configurations of the City Power networks. The outcome of this reliability modelling enabled the Engineering Operations division to propose reasonable “expected” SAIDI and SAIFI target ranges for the City Power networks, and facilitated a better understanding of the expected performance of all the networks (feeders and substations) in their area of supply. The outcome of the study was also used to develop network criticality maps, highlighting the networks that significantly contribute to the system SAIDI. |
