Prioritization of underground transmission cable renewal projects in power electric utility companies

This paper reviews the current asset management methodologies in power electric utility companies and identifies the present challenges and problems encountered by utility companies with the current methodologies in managing and prioritizing underground transmission cable asset renewal projects. This paper proposes as an addition to the current methodologies, a more systematic framework for evaluating and ranking underground transmission cable asset renewal investment projects based on the modelling of uncertainties and on determining the relative importance of a particular transmission line circuit in the power system as it affects the bulk power system reliability.
