Hitachi Energy will design and develop the first phase of visionary NEOM region transmission system

The Yanbu-NIC HVDC interconnection is an HVDC Light® project, enabling development of NEOM in Saudi Arabia with up to 9 gigawatts of power transmission capacity.

Once completed, the high-voltage direct current (HVDC) transmission systems will have a total power capacity of up to 9 gigawatts (GW) and consist of three HVDC transmission links.

This link, the Yanbu-NIC link, is the first of three links and one of the world’s first 3 GW, 525 kilovolt (kV) HVDC Light® transmission system. This HVDC system will connect Oxagon, NEOM’s regional development, with the larger Yanbu area more than 650 kilometers away in Western Saudi Arabia. Built with sustainability in mind, NEOM will be powered by 100 percent clean energy, through renewable solar, wind and green hydrogen-based energy.

The Yanbu-NIC link consists of two converter stations connected via overhead lines, where each station consisting of two asymmetrical monopoles in a bipole configuration, connected to the 380 kV AC grids. The converter stations are designed to deliver 2x1,500 MW of electricity, at a nominal DC voltage of ± 525 kV.

This project is enabler for the electrification of the global energy system and the transition to renewables.
