Decarbonization of the Saudi Power Grid: A Techno-Economic and Environmental Assessment of Advanced Conductors
Main Article Content
Abstract
In response to Saudi Arabia’s commitment to achieving net-zero emissions by 2060, this paper explores the role of advanced overhead line conductor technologies in decarbonizing the nation’s power grid. Recognizing the urgent need to reduce greenhouse gas (GHG) emissions in the electrical sector, a detailed techno-economic and environmental analysis is carried out. The research develops a practical assessment framework that combines analytical methods with statistical tools to compare the performance of conventional conductors with newer, more efficient alternatives. Particular emphasis is placed on the ability of advanced conductors to cut line losses, improve energy efficiency, and lower the environmental impact of transmission networks. To ground the analysis in real-world conditions, the study features a case investigation of an existing 380 kV transmission line in Saudi Arabia. Here, ACSR, ACAR, ACCC, and AAAC conductor types are evaluated using a custom-developed calculation tool, which has been validated against recognized industry standards. Through this work, the study aims not only to assess the technical and economic viability of adopting greener transmission solutions but also to support broader sustainable energy practices across the Kingdom.
