The global HVDC (High Voltage Direct Current) transmission system market is witnessing steady growth, driven by rising electricity demand, rapid renewable energy integration, and the growing need for long-distance, efficient power transmission. HVDC technology plays a critical role in supporting carbon-neutral energy systems by enabling low-loss power transfer, grid interconnection, and large-scale renewable energy evacuation.
According to Fortune Business Insights, the global HVDC transmission system market was valued at USD 11.70 billion in 2025 and increased to USD 12.60 billion in 2026. The market is projected to reach USD 22.29 billion by 2034, registering a CAGR of 7.39% during 2026-2034. In 2025, Asia Pacific dominated the market with a 67.65% share, supported by large-scale power infrastructure investments and renewable energy expansion.
HVDC systems convert AC power into DC at converter stations, transmit electricity via overhead, underground, or subsea cables, and reconvert it to AC at the receiving end. These systems are highly suitable for long-distance transmission, submarine cable systems, and interconnection of asynchronous AC grids.
Market Impact Analysis
The COVID-19 pandemic temporarily affected the HVDC transmission system market due to reduced electricity demand and disruptions in manufacturing and supply chains. However, post-pandemic recovery has been strong, supported by increased government focus on infrastructure investment, grid resilience, and energy security. The shift away from fossil fuels toward renewable energy sources such as wind and solar has further strengthened the market outlook.
HVDC Transmission System Market Trends
Growing grid interconnections are a major trend driving market growth. Countries are increasingly interlinking regional and cross-border power grids to enhance energy security and facilitate renewable energy integration. HVDC systems enable efficient long-distance transmission with minimal losses, making them ideal for connecting offshore wind farms, remote solar projects, and hydropower stations to demand centers. Government-backed interconnection initiatives are accelerating global HVDC deployment.
Market Growth Factors
Growing Adoption of Voltage Source Converter (VSC) Technology
The increasing adoption of VSC-based HVDC systems is a key growth driver. VSC technology allows independent control of active and reactive power, black-start capability, and seamless integration into multi-terminal DC networks. Compared to conventional systems, VSC-based HVDC offers enhanced flexibility and faster power flow control, making it highly suitable for renewable energy applications.
Rising Number of HVDC Projects Globally
The number of HVDC projects is increasing rapidly across Europe, China, North America, and South America. Improved cost-benefit performance, growing renewable capacity, and rising domestic power trading are driving HVDC adoption. Technological advancements have further improved system reliability and economic feasibility.
Restraining Factors
High initial investment costs, particularly for short-distance transmission, remain a major restraint. HVDC systems require expensive converter stations, transformers, control equipment, and auxiliary systems. For shorter distances, HVDC projects can be more costly than traditional AC transmission, limiting adoption in certain applications.
Market Segmentation Analysis
By Type
Based on type, the market is segmented into high-power rating projects and low-power rating projects. Low-power rating projects emerged as the dominant segment, accounting for 70.06% market share in 2026, driven by rising renewable energy installations in remote locations.
By Application
By application, the market is segmented into overhead, underground, subsea, and mixed systems. Overhead HVDC transmission dominated the market, generating USD 6.38 billion in 2026 and holding a 50.65% share, owing to lower installation costs and higher power-carrying capacity.
By Technology
Based on technology, the market is divided into Line Commutated Converter (LCC) and Voltage Source Converter (VSC). LCC technology dominated the market in 2026, with a value of USD 9.00 billion and a 71.46% market share, due to its reliability, efficiency, and suitability for bulk power transmission.
Asia Pacific led the global HVDC transmission system market with a market size of USD 7.91 billion in 2025, driven by strong industrial growth and government-supported grid expansion programs. China reached USD 5.75 billion by 2026, followed by India at USD 1.24 billion.
North America accounted for 15.14% market share in 2025, supported by renewable energy adoption and transmission infrastructure upgrades.
Europe held 9.6% market share in 2025, driven by offshore wind integration and cross-border grid projects.
Competitive Landscape
The market is moderately consolidated, with key players including Hitachi Energy, Siemens, Nexans, Toshiba Energy Systems, Mitsubishi Electric, GE, Prysmian Group, and NKT. Companies are focusing on large-scale HVDC projects, advanced converter technologies, and grid modernization initiatives.
Conclusion
The global HVDC transmission system market is set for sustained growth, expanding from USD 11.70 billion in 2025 to USD 22.29 billion by 2034. Rising renewable energy integration, increasing grid interconnections, and the adoption of advanced VSC technologies are key growth drivers. Asia Pacific's strong market dominance highlights the role of emerging economies in shaping future power transmission infrastructure. Despite high initial costs, continuous technological advancements and government-backed infrastructure investments are expected to support steady market expansion throughout the forecast period.
