Saudi Arabia’s HVDC transmission sector is gaining importance as the Kingdom expands renewable energy, strengthens grid interconnection, and develops large power projects across distant regions. High-voltage direct current transmission is used to move large volumes of electricity over long distances with lower losses than many conventional AC systems. In a country with vast geography, major load centers, and renewable energy projects located far from consumption hubs, HVDC can support efficient and stable power transfer.

According to MarkNtel Advisors, Saudi Arabia’s HVDC transmission sector was valued at around USD 3.12 billion in 2025 and is projected to grow from USD 3.38 billion in 2026 to USD 5.45 billion by 2032. The sector outlook indicates a CAGR of 8.23% during 2026–2032, supported by renewable integration, interregional grid connectivity, voltage source converter systems, overhead transmission lines, and growing electricity demand from industrial and urban development.

Renewable Energy Expansion Is Driving HVDC Demand

Saudi Arabia’s renewable energy projects are creating a stronger need for long-distance transmission infrastructure. Solar and wind resources are often located away from major demand centers, requiring efficient power transfer across large distances. HVDC systems can help connect generation zones with cities, industrial clusters, and export-oriented interconnection points.

Vision 2030 supports economic diversification, renewable energy, industrial development, and infrastructure modernization. As the Kingdom adds more clean power projects, transmission networks will need to handle variable generation and move electricity reliably across regions. HVDC systems are suited for this role because they can improve controllability and reduce transmission losses in long-distance applications.

Voltage Source Converter Systems Are Gaining Preference

Voltage source converter systems account for about 48% share of Saudi Arabia’s HVDC transmission sector in 2026. VSC technology is gaining importance because it offers better control over active and reactive power, supports weak grids, enables black-start capability in some configurations, and can integrate renewable generation more flexibly.

This makes VSC-HVDC particularly relevant for renewable energy zones, offshore or remote power connections, and interregional grid reinforcement. Compared with older line-commutated converter systems, VSC technology offers operational flexibility, although it can involve higher equipment complexity and cost.

Overhead Lines Remain the Main Transmission Route

Overhead transmission lines account for around 70% share by installation type. Their dominance is linked to Saudi Arabia’s geography, long distances, and the need for cost-effective high-capacity electricity movement across deserts and remote regions. Overhead HVDC lines can be more economical than underground or submarine cables for long inland routes.

However, overhead line development requires careful planning around land use, environmental impact, right-of-way permissions, tower design, and maintenance access. In desert environments, heat, sand, and dust can also affect equipment design and operational planning.

Grid Interconnection Is Becoming More Strategic

HVDC transmission is also relevant for regional power interconnection. Saudi Arabia is connected with Gulf Cooperation Council electricity networks and is exploring wider power exchange opportunities. HVDC can support controlled power flows between grids, improve stability, and enable cross-border electricity trade where technical conditions differ.

The Gulf Cooperation Council Interconnection Authority supports electricity interconnection among GCC states, improving grid reliability and enabling power exchange. As regional energy cooperation grows, HVDC systems may become more important for linking renewable resources, balancing supply, and improving system resilience.

Industrial Growth Adds Electricity Demand

Saudi Arabia’s industrial expansion is increasing electricity requirements across mining, petrochemicals, manufacturing, water desalination, logistics, data centers, and giga-projects. These demand centers require stable and high-capacity electricity supply. HVDC can help move power from generation hubs to industrial load centers efficiently.

The International Energy Agency notes Saudi Arabia’s role as a major energy producer and its growing focus on efficiency, renewable energy, and power sector transformation. Transmission expansion is essential to support this transition because generation additions must be matched with grid capacity and reliability.

High Capital Cost Remains a Challenge

HVDC projects require large investments in converter stations, transformers, control systems, overhead lines, protection equipment, and civil infrastructure. Project planning also involves technical studies, grid integration, land permissions, and skilled engineering. These factors can make HVDC more expensive upfront than conventional transmission options, even when lifecycle efficiency benefits are attractive.

The International Renewable Energy Agency emphasizes that power system infrastructure and flexibility are essential for integrating higher shares of renewable energy. For Saudi Arabia, HVDC investment will depend on project scale, financing models, renewable deployment pace, and long-term grid planning.

Looking Ahead

Saudi Arabia’s HVDC transmission sector is expected to grow steadily as renewable energy projects, industrial demand, regional interconnection, and long-distance grid expansion continue. With the sector projected to reach USD 5.45 billion by 2032 at a CAGR of 8.23%, demand is likely to remain strongest in voltage source converter systems, overhead lines, renewable integration, and interregional power transfer. The long-term direction will depend on capital investment, grid planning, land approvals, technology selection, and the ability of HVDC systems to support reliable electricity movement across the Kingdom’s expanding energy landscape.
