Lifecycle cost optimization of electric utility transmission and distribution assets

Abstract

This paper presents industry best practices to optimize lifecycle cost of electric transmission and distribution (T&D) assets whilst maintaining asset integrity, functionality and operability. This qualitative study encompasses high voltage plant and equipment in the electric power transmission and distribution sector, and focusses on asset strategy, equipment evaluation and specification. Asset managers must apply a structured approach and have a long term view in order to achieve the lowest lifecycle cost; whilst meeting regulatory and consumer requirement within acceptable risk exposure. This research study provides context and proposes tools and methodologies which can be utilized for effective decision making across the full supply chain for primary and secondary transmission and distribution equipment.
