Türkiye explores cross-border power corridor with Saudi Arabia and regional neighbours

Türkiye has initiated discussions with Saudi Arabia, Jordan and Syria regarding the development of a major cross-border electricity transmission corridor connecting the regional networks. The prospective interconnector aims to establish a shared electrical bridge linking south-eastern Europe and Anatolia with the Arabian Peninsula, facilitating bi-directional power transfers, bulk wheeling and enhanced regional system balancing.

For transmission system operators, substation engineers and industrial asset managers, a project of this scale introduces profound technical considerations. Long-distance power transfers across diverse synchronous systems typically necessitate high-voltage direct-current converter stations or heavily reinforced alternating-current switching yards equipped with dynamic reactive power compensation. Integrating vast transmission corridors across multiple operating jurisdictions creates distinct voltage stability challenges and increases short-circuit duties on existing terminal switchgear. Substations positioned along the transit corridor will require robust transformer fleets capable of enduring continuous high-load throughput, elevated thermal stress and dynamic network swings.

Furthermore, harmonising disparate transmission networks requires significant substation automation upgrades and protective relay coordination across national borders. Connecting stations will necessitate specialised transformers capable of handling increased harmonic distortion, along with high-voltage gas-insulated switchgear installations engineered to withstand harsh environmental conditions across arid and variable transit routes.

What this means for asset owners in Türkiye: grid operators and transmission asset owners in Türkiye face protracted procurement lead times and heightened manufacturing competition for high-voltage power transformers and converter equipment. Transmission planners must evaluate regional substation fault levels and thermal ratings well in advance of interconnector commissioning to avoid severe transfer bottlenecks and prevent forced system outages during peak cross-border power flows.
