Global Offshore Wind VSC-HVDC Converter Valve Market Strategic Research Report

Scope of the Report

The global Offshore Wind VSC-HVDC Converter Valve market size is predicted to grow from US$ 1,087 million in 2025 to US$ 3,843 million in 2032; it is expected to grow at a CAGR of 19.2% from 2026 to 2032.

The Offshore Wind VSC-HVDC Converter Valve** is the core power conversion equipment used in flexible HVDC transmission systems for large-scale offshore wind farms in mid- to deep-sea and far-offshore areas. Typically employing fully controlled power semiconductors such as IGBTs and a modular multilevel (MMC) topology, these converters transform the AC power aggregated from the wind farm into high-voltage DC at the offshore converter station. The DC power is then transmitted to land via subsea DC cables, where it is converted back to AC at the onshore converter station and fed into the power grid.

In 2025, global sales of F-HVDC converter valves for offshore wind power reached 10,015 MW, with an average price of $105.48/kW.

Development Trends

Upgrades from ±320/500 kV to ±525/640 kV and ±800 kV

European offshore wind power has evolved from 900 MW-class platforms to 2 GW-class 525 kV platforms. Hitachi Energy’s current HVDC Light technology capabilities now cover up to approximately 3,000 MW at the ±640 kV level.

MMC Has Become the Absolute Mainstream

Traditional two-level and three-level VSCs are gradually being phased out of new large-scale projects in the high-voltage transmission sector. MMC has become the core architecture due to its advantages, including modularity, good voltage scalability, low harmonics, lower device switching frequencies, and ease of redundancy design.

Siemens’ HVDC PLUS explicitly adopts the MMC; Mitsubishi’s HVDC-Diamond also employs the MMC architecture, covering capacities ranging from 50 MW to over 1,000 MW.

IGBTs Remain Dominant, but IGCT Market Share Will Increase Significantly

Currently, high-voltage butt-jointed IGBTs still dominate the global commercial HVDC market. However, China is actively promoting the development of high-voltage, high-current IGCT technology.

Offshore wind power has become the largest source of demand in Europe

For deep-sea wind farms located 100–300 km or more from the coast, AC transmission is constrained by reactive power and cable charging currents, making HVDC significantly more economical.

In the future, the European North Sea will become the world’s largest market for **±525 kV, 2 GW-class VSC-HVDC converter valves. TenneT’s 2 GW standardization plan has already shifted HVDC converter equipment procurement from “project-specific customization” to “platform-based bulk procurement.”
