Asia Pacific High Voltage Direct Current Hvdc Transmission Systems Market Industry: Market Size & Forecast 2026

HVDC transmission systems use DC rather than AC to move electricity, lowering losses over long distances and enabling connections between asynchronous grids or offshore generation sites. The Asia Pacific market is estimated at approximately USD 6.7 billion in 2025, representing the dominant share of the global HVDC market by region. Private market-research estimates cluster between USD 6.0 billion and USD 7.9 billion for 2025, with a consensus forward CAGR of roughly 8% through the early 2030s, reflecting the scale of grid investment across the region.

• •Regional value in 2025: approximately USD 6.7 billion, the largest geographic segment worldwide
• •Forward CAGR: around 8.0% per year, among the highest growth rates in the global power-equipment value chain
• •No government statistical agency publishes a comprehensive composite HVDC market figure; data is from private research

The most powerful growth drivers are the rapid build-out of utility-scale solar and wind, particularly in China's interior and western provinces and in offshore wind clusters around China, Taiwan, South Korea, Vietnam, and Japan. Cross-border and subsea interconnectors are also expanding, including planned links between provinces in China, between mainland and island grids in Japan, and between Singapore, Malaysia, and Indonesia. Policy commitments to decarbonization and grid resilience are translating into multi-billion-dollar transmission infrastructure programs across the region.

• •Renewable energy integration, especially offshore wind, is the leading demand source for new HVDC links
• •Cross-border interconnector projects and subsea transmission cables are accelerating in South and Southeast Asia
• •Grid modernization, decarbonization targets, and aging AC infrastructure replacement support long-cycle investment

By technology, the market splits into Line Commutated Converter (LCC) and Voltage Source Converter (VSC) systems, with LCC historically dominant for very high-capacity overhead projects and VSC increasingly preferred for offshore wind, subsea, and urban infeed applications. By configuration, point-to-point systems account for the majority of installed capacity, with back-to-back and multi-terminal schemes representing a smaller but rapidly growing share. By geography, China is by far the largest national market, followed by India, Japan, South Korea, and Australia, with emerging activity in Vietnam, Indonesia, and Malaysia.

• •LCC and VSC are the two main converter technologies, with VSC gaining share in offshore and subsea projects
• •Point-to-point links dominate today, but multi-terminal HVDC is an emerging segment
• •China leads regional spending; India, Japan, South Korea, and Australia are the next-largest national markets

What are the recent trends and outlook?

Through 2030 the market is expected to be shaped by an accelerating shift toward VSC and multi-terminal HVDC topologies that better suit offshore wind and complex grid integration. Submarine and underground cable demand is forecast to grow at a notably faster pace than overhead lines, with private forecasts indicating low-double-digit annual growth for the HVDC cable sub-market in Asia Pacific. Overall, the combination of policy-driven renewables expansion, offshore wind build-out, and interconnector projects is expected to keep the region the world's largest and fastest-evolving HVDC market for the remainder of the decade.

• •VSC and multi-terminal HVDC are the leading technological trends, replacing or supplementing legacy LCC systems
• •HVDC cable demand, including subsea links, is forecast to grow at a higher rate than the wider HVDC market
• •Asia Pacific is expected to remain the largest and most dynamic regional HVDC market globally through 2030 and beyond
