Hitachi Energy will upgrading the Al-Fadhili high-voltage direct current (HVDC) converter station to ensure power security and grid stability

Hitachi Energy and Gulf Cooperation Council Interconnection Authority (GCCIA) have signed the contract to upgrade the Al-Fadhili high-voltage direct current (HVDC) converter station under the GCCIA authority in Saudi Arabia creating a resilient interconnected grid, ensuring power security, and economic benefits.

The Al-Fadhili converter station interconnects the power grids of Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates and once upgraded, the Al-Fadhili station will be able to exchange up to 1,800 megawatts of electricity between these states while maintaining the stability of the connected grids.

The Al-Fadhili HVDC converter station is a back-to-back system that utilizes the sophisticated, digital controllability of an HVDC system to precisely manage the flow and properties of the electricity supply, providing many benefits for grid control and stability.

Within this project, hardware and software will be replaced with Hitachi Energy’s cutting-edge MACH™ control and protection system, the brain behind HVDC links.

In addition to benefits above, this project will allow optimization in electricity generation resulting in reduced CO2 emissions by minimizing the need for additional power generation, ensuring a secure power supply for the countries of the region.
