GE Vernova’s Electrification business has announced a research and development contract with four German Transmission System Operators (TSOs). The agreement with TenneT TSO, 50Hertz Transmission, Amprion, and Transnet BW is for the design and engineering of a multi-terminal/multi-hub high-voltage direct current (HVDC) connection solution.
HVDC is the most efficient way to transmit bulk power over long distances and is essential for integrating renewable wind and solar energy into the grid. Currently, HVDC systems use point-to-point, bi-directional transmission with one HVDC converter station at each end. GE Vernova, in partnership with the four German TSOs, aims to develop a new generation of multi-terminal HVDC technology, enabling multiple terminals to connect with one another. This multi-terminal grid will allow electricity to travel where needed for a highly efficient electron highway.
The R&D contract also includes the conceptualisation, design, and development of enabling technologies, specifically a new 525 kV direct current circuit breaker (DCCB). This technology will allow TSOs to trip and isolate faults in the HVDC system. GE Vernova is currently in the development phase of the DCCB.
The initial R&D award covers an 18-month design phase through December 2025, with the implementation phase scheduled to begin in 2026. Commercial deployment is expected by 2029. The project will be led by GE Grid in Berlin, with engineering conducted at GE Vernova’s HVDC facility in Stafford, UK.
