ELECTRIFICATION IN MOTION

As Europe races to build the infrastructure needed for artificial intelligence at scale, power transmission is becoming just as important as processors and data halls. In Seine-et-Marne, south of Paris, a new milestone is taking shape with what is expected to become Europe’s largest AI campus - a project designed by Campus AI to deliver up to 1.4 GW of capacity and support the full AI life cycle.

GE Vernova is expected  to supply a 420 kV SF₆-free (g³) Gas-Insulated Switchgear (GIS) system, including multiple bays and associated high-voltage equipment, based on its T155g platform, for the project. The agreement, signed in January 2026, provides critical grid infrastructure for a facility expected to reach a total capacity of 1.4 GW. 

Campus AI, a joint venture between Bpifrance, MGX, Mistral AI, and NVIDIA, is designed to deliver sovereign, low-carbon hyperscale computing. Located in France, whose electricity mix is among the most decarbonized in Europe, the project benefits from a structural low-carbon advantage. By choosing GE Vernova's SF₆-free technology, Campus AI reinforces this commitment while aligning with the "Choose France" program and leveraging French engineering and localized service teams.

The T155g is part of GE Vernova’s GRiDEA portfolio, a range of SF₆-free GIS solutions designed to reduce the global warming potential of the insulating gas by 99% compared to traditional sulfur hexafluoride (SF₆). This environmental benefit is achieved without increasing the physical dimensions of the equipment or compromising operational reliability and performance. While this contract focuses on the 420 kV transmission level, the SF₆-free GIS range also extends to lower-voltage applications, supporting a broad spectrum of data center sizes and regional grid requirements across Europe.

As Eric Chaussin, VP and CEO Power Transmission at GE Vernova, puts it: “The energy demands of AI-scale computing require grid infrastructure that is both high-capacity and decarbonized. This contract demonstrates that 420 kV SF₆-free technology is a viable, high-performance solution for data center developers and infrastructure providers who must balance rapid scale with aggressive decarbonization targets. Our manufacturing and engineering capabilities ensure we can meet the accelerated timelines required for this strategic European asset."

Thibaud Desfossés, CEO of Campus AI, noted: "Securing high-voltage grid infrastructure at this scale marks a decisive step: Campus AI is moving from vision to delivery.”

GE Vernova’s scope for the 2027 delivery focuses on the T155g units, establishing the primary high-voltage interface between the national transmission grid and the 1.4 GW campus. The project is expected to expand with additional infrastructure packages as the campus scales its operations.
