Hitachi Energy, a global technology leader advancing a sustainable energy future for all, has signed agreements under the supervision and management of the Ministry of Energy with the Saudi Electricity Company (SEC) and with ENOWA. The agreements include the supply of three high-voltage direct current (HVDC) transmission systems to end customer ENOWA, the utility company for NEOM in Northwest Saudi Arabia. The three HVDC links will have a total power capacity of up to 9 gigawatts (GW).
The agreements include an order from ENOWA’s engineering, procurement and construction management (EPCM) partner, the Saudi Electricity Company (SEC) awarded to Hitachi Energy and its consortium partner, Saudi Services for Electro Mechanical Works (SSEM), to provide one of the world’s first 3 GW, 525 kilovolt (kV) HVDC Light® transmission system connecting Oxagon, NEOM’s regional development.
Hitachi Energy’s scope of supply includes design, engineering, procurement of HVDC technology and commissioning of the HVDC Light converter stations. Whilst SSEM – a leading Saudi EPC specialized in power, water and industrial projects – will design and supply the AC equipment portion and perform the construction and the installation. The converter stations convert the power from AC to DC then back to AC for integration into the receiving grid. The converters will be sourced by and supplied to Saudi Electricity Company, who were contracted in 2022 by ENOWA to act as their EPCM to build this first HVDC system for NEOM.
Further to this, Hitachi Energy and ENOWA have signed an early works and capacity reservation agreement for two additional HVDC projects, each rated up to 3 GW. Under this agreement, both companies commit to having the resources and capacity necessary to implement these two HVDC systems. As part of a new scalable and modular regional network design that is targeted to seamlessly integrate future renewables and energy storage technologies in the NEOM Energy System, making it unique in terms of size and complexity. The co-operation will also explore opportunities to develop local competencies in the Kingdom, including ways to sustainably assemble the necessary HVDC Light components locally.

Hyundai Engineering & Construction (Hyundai E&C) has secured a contract to construct a high voltage direct current (HVDC) transmission line in Saudi Arabia. Hyundai E&C will be handling the construction of 207 km of transmission lines and approximately 450 transmission towers, known as the Portion 1 project. The completion of the project is expected in July 2027.

Arabian Electrical Transmission Line Contracting (AETCON) has secured a contract to construct a high voltage direct current (HVDC) transmission line in Saudi Arabia. The $155 million contract involves expanding the power network by constructing a HVDC transmission line over a total distance of 605 km from Yanbu, a power production hub on the western coast of Saudi Arabia, to the new city of Neom.
