As the world accelerates its transition to renewable energy, high-voltage direct current (HVDC) technology has become a cornerstone for efficient energy transmission. This cutting-edge technology is enabling the long-distance transport of electricity generated from renewable sources, such as wind and solar power, to where it is most needed. In this context, GE Vernova’s new HVDC valve factory plays a pivotal role in meeting the increasing demand for HVDC systems. Among the key innovations being developed at this facility is the hybrid valve—a technology that promises to improve the reliability and efficiency of HVDC systems.
This article will take a closer look at the state-of-the-art HVDC valve factory, its role in the energy transition, and the significance of hybrid valves in modern energy infrastructure.
What is HVDC and Why is it Important?
High-Voltage Direct Current (HVDC) is a technology used to transmit large amounts of electricity over long distances with minimal losses. Unlike traditional alternating current (AC) transmission, HVDC systems are more efficient, especially when it comes to transporting electricity across long distances or through underwater cables. This is particularly crucial for renewable energy projects, which are often located far from population centers, such as offshore wind farms or solar power plants in remote areas.
HVDC transmission is essential for integrating renewable energy into the grid. It provides the flexibility needed to connect grids of different frequencies, stabilizing power supply while also reducing the environmental impact of energy transport. The ability to transport large volumes of renewable energy with minimal energy losses is key to the global shift towards sustainable power sources.
The Role of HVDC Valves in Energy Transmission
At the heart of HVDC technology lies the HVDC valve—a critical component in converting AC to DC power (and vice versa) within the system. HVDC valves use semiconductor components to control and rectify the flow of electricity, enabling efficient and reliable transmission of power. As HVDC systems become more complex and larger in scale, the performance and reliability of these valves are paramount.
In the past, traditional HVDC valves were based on thyristor technology. However, with the growing demands for higher capacity and greater efficiency, modern HVDC valves incorporate advanced semiconductor devices such as insulated-gate transistors (IGBTs). These new valves not only increase the performance of HVDC systems but also improve their operational flexibility.
Hybrid Valve: The Next Step in HVDC Evolution
One of the key innovations emerging from GE Vernova’s HVDC valve factory is the hybrid valve. The hybrid valve combines the best features of traditional thyristor-based valves and newer, more efficient semiconductor technologies like IGBTs. This hybrid design offers several advantages:

They can switch more efficiently and provide better control over the power flow, which is crucial for stabilizing the grid and integrating renewable energy sources.
- Increased Reliability: Hybrid valves are designed for greater resilience. By improving the balance between thyristors and IGBTs, they can better withstand high-voltage conditions and electrical surges, ensuring more reliable and robust performance over time.
- Cost-Effectiveness: Although the hybrid valve incorporates advanced technology, it offers cost advantages by optimizing the use of materials and components. By merging two types of valve technology into one, GE Vernova has been able to create a more cost-effective solution without compromising performance.
- Faster Response Times: The hybrid valve offers quicker switching speeds, which is especially beneficial for dynamic grid applications and high-demand periods. This is essential for maintaining grid stability as renewable energy sources like wind and solar can be unpredictable, with generation levels fluctuating throughout the day.
- Scalability: The hybrid valve design is highly scalable, making it suitable for a variety of projects, from small-scale regional grids to large, cross-border HVDC systems that can transmit power across entire continents.
