Report Overview

The Global HVDC Converter Stations Market size is expected to be worth around USD 25.8 Billion by 2034, from USD 13.0 Billion in 2024, growing at a CAGR of 7.1% during the forecast period from 2025 to 2034.

HVDC power transmission involves sending electricity from power plants to end users via high-voltage direct current lines, enabling efficient long-distance transfer and the interconnection of networks with different frequencies. It relies on switching valves, traditionally thyristors, and increasingly insulated-gate bipolar transistors (IGBTs) to manage unidirectional DC flow.

AC prevailed due to the high cost and complexity of DC systems. Modern power electronics have since made HVDC economically viable. In a typical setup, power enters a converter station for AC-to-DC conversion, travels via HVDC cables, and is converted back to AC at the receiving end for distribution. The Office of Electricity champions HVDC research for these advantages and recently celebrated the winners of the American-Made HVDC Prize, which will address deployment barriers through innovative hardware, controls, and concepts.

The HVDC Cost Reduction (CORE) Initiative targets a 35% cost reduction in HVDC technology and long-distance transmission by 2035, with a focus on domestic manufacturing to meet all U.S. demands competitively. HVDC excels over high-voltage AC (HVAC) by eliminating capacitive charging currents, especially in subsea cables, and removing the need for frequency and phase synchronization.

• It also enables power exchange between 50 Hz and 60 Hz networks. The world’s longest HVDC link was the 2,000 km line from Xiangjiaba Dam to Shanghai, when Brazil’s 2,375 km Rio Madeira project took the title, serving São Paulo. Though a late adopter, China rapidly advanced HVDC technology. The 1987 Zhoushan project marked its start; 13 projects totaling 23,720 MW were operational, supporting west-to-east transmission and national grid integration.

Emerging Trends

HVDC Converter Stations Powering Offshore Energy Hubs and Hybrid Grids

As offshore wind targets rise, the grid story is changing fast. Across the EU, countries have agreed offshore wind goals in the range of 86–89 GW by 2030, 259–261 GW by 2040, and 356–366 GW by 2050. These volumes simply cannot move efficiently without long-distance, high-capacity HVDC links and converter stations that can manage complex power flows between multiple countries.

• One clear sign of this shift is the push for energy islands and offshore hubs. The Bornholm Energy Island in the Baltic Sea, for example, will connect a 3 GW offshore wind cluster to both Denmark and Germany. The EU has approved a grant of €645 million for this project through the Connecting Europe Facility, making it a flagship for transnational HVDC-based infrastructure.

In these hubs, HVDC converter stations do more than just convert AC to DC. They allow operators to route power flexibly between several grids, stabilize asynchronous systems, and support black-start capabilities. That means fewer curtailments and better use of every megawatt produced offshore.

Drivers

Rapid Growth of Variable Renewables Demands Long-Distance HVDC Backbones

Global renewables are now expanding at a pace that makes grid planners nervous and hopeful at the same time. In 2024, the world added about 585 GW of renewable capacity, taking total installed renewables to around 4,448 GW. Solar and wind made up the vast majority of this build-out, and both depend on strong long-distance transmission.

• IRENA’s 1.5°C pathway says renewable power capacity needs to reach more than 11,000 GW by 2030 to stay on track, with solar and wind providing roughly 90% of additions. That kind of expansion scatters generation far from traditional load centers and deep into offshore zones, deserts, and high-resource regions. HVDC converter stations become the practical way to connect these new clusters to urban demand without excessive losses.

Grid experts are blunt about the consequences. IRENA notes that the goal of tripling renewable power by 2030 makes planning and investing in grid development even more urgent, precisely because wind and solar are spread across many locations and need stronger transmission backbones. AC systems alone struggle with stability, congestion, and losses over very long distances.

Restraints

Supply-Chain Bottlenecks and Long Lead Times for Critical HVDC Components

The biggest brake on HVDC converter station deployment today often sits in the factory, not the parliament. The International Energy Agency’s work on transmission grids shows how strained equipment supply has become. For cables and large power transformers, average procurement lead times have almost doubled, now reaching two to three years for cables and up to four years for big transformers.

Direct-current cable systems, which are essential for HVDC links, are under even greater stress. Industry surveys cited by the IEA highlight that waiting times for specialised DC cables can extend beyond five years, squeezing project schedules before construction even starts. Developers can win auctions, secure permits, and still sit idle because the converter transformers, valves, and cables are simply not available.

On top of timing issues, only a handful of global suppliers can deliver the most complex HVDC systems at scale. That concentration raises concerns about competition, pricing power, and resilience if one manufacturer faces technical problems or financial stress. For emerging markets, tight manufacturing capacity can mean longer queues and higher prices than wealthier regions, limiting their ability to adopt modern HVDC solutions quickly.

Opportunity

Massive Grid Investment Plans and Public Funding to Cut HVDC Costs

The financial pipeline for grids and HVDC looks increasingly strong. A coalition led by the Global Renewables Alliance has endorsed a target of around USD 700 billion per year in grid infrastructure investments, along with adding or upgrading over 80 million kilometers of transmission and distribution lines. HVDC corridors and converter stations sit at the center of those plans.

• Governments are not just talking about investment; they are putting money on the table to de-risk new HVDC technologies. In the United States, the Department of Energy’s Office of Electricity and Wind Energy Technologies Office has launched a USD 10 million funding opportunity to drive innovation in HVDC voltage-source converter systems. The aim is to lower costs, raise power capacity, and shrink substation footprints so that HVDC becomes easier to deploy across the grid.

DOE initiatives on transmission acceleration and DC-grid innovation are designed to make HVDC systems cost-comparable with traditional AC transmission and to reduce permitting friction for major corridors. Similar support schemes are being shaped in Europe and parts of Asia, where grid operators are under pressure to connect offshore wind clusters and cross-border interconnectors quickly.
