GE Vernova has secured a contract from TransnetBW to revamp the Kühmoos grid node in southern Germany, a pivotal substation for cross-border electricity exchange and regional network stability.
The project will strengthen frequency regulation, voltage stability and power transfer between Germany, France, and Switzerland.

Located near the Swiss border, the Kühmoos substation is an essential transmission hub that connects two significant pumped-storage hydropower plants.
This modernisation forms part of Germany’s wider initiative to fortify its electrical infrastructure.
By upgrading Kühmoos, there will be an increase in the capacity and reliability necessary to integrate renewable energy sources and manage increased power flow across Europe’s interconnected grids.
TransnetBW CFO Rainer Pflaum stated: “At the substation Kühmoos of TransnetBW, we are reinforcing a vital energy hub for both Germany and our neighbouring countries, France and Switzerland. The collaboration with GE Vernova supports our ambition to expand and future-proof our transmission network while continuing to operate reliably and safely.

By GlobalData“This modernisation is therefore a major milestone in the transformation of our grid, ensuring the electricity supply in south-western Baden-Württemberg.”
GE Vernova’s grid solutions division is tasked with delivering a new 380kV gas-insulated substation (GIS) on a turnkey basis.
This GIS will replace older air insulated switchgear technology, which is expected to double the current capacity while occupying less space, all without interrupting ongoing operations during construction.
The upgrade includes installing 15 bays of compact GIS technology along with a 4 main busbar system for more efficient power distribution.
This project incorporates mechanical switched capacitor with damping network (MSCDN), which aids in voltage regulation and minimises losses as higher volumes of electricity traverse through the network.
GE Vernova grid systems integration vice-president and CEO Johan Bindele stated: “This is a landmark project for the region and a proud moment for GE Vernova.
“Modernising critical grid nodes like Kühmoos is essential for supporting the long-term reliability of Europe’s power system, especially as countries expand their use of renewables and seek greater interconnection across borders. Europe is our largest market for electrification, and we are deeply committed to supporting its energy transition. We are honoured to support TransnetBW in building grid infrastructure that is both future-ready and resilient.”
GE Vernova recently announced the commencement of operations for the first block of the Hsinta power plant, which is managed by the Taiwan Power Company Nan Bu Construction Organisation (TPC NPCO).
The block, equipped with GE Vernova’s advanced 7HA.03 combined cycle technology, has the capacity to deliver 1.3GW of electricity to Taiwan’s energy grid.
