On Econometric Model of Total Cost of Ownership (TCO) in Transmission Line Design, Maintenance and Operation

The article proposes to address the planning and design of transmission infrastructure by employing a stochastic modeling framework for evaluating the Total Cost of Ownership (TCO) of electric transmission lines over a 50+ year horizon. The novel approach provides both timely and innovative slant on transmission line design, construction and operation. This approach is particularly pertinent given the uncertainties in load growth, technological advancements in materials and design, and environmental factors. The paper presents an overview of the currently used methodologies and literature on the subject, along with an assessment of the novelty and potential impact of this new approach.
