Sesterce "Rhône-Alps" AI Mega-Campus

Status: Latest Launch (Active Execution Phase - Jan 2026)   |   Location: Lyon-Valence Logistics Hub, Auvergne-Rhône-Alpes

Project Overview

The Sesterce "Rhône-Alps" AI Mega-Campus is the most ambitious digital infrastructure project launched in Europe to start 2026. Formally transitioning from planning to active execution on January 18, 2026, this campus is designed to serve as the sovereign backbone for European Artificial Intelligence. Located in the strategic corridor between Lyon and Valence, the project leverages France’s uniquely stable and low-carbon energy grid to provide 1 Gigawatt (GW) of initial capacity, with a long-term roadmap expanding to a staggering 3 GW.

What sets this project apart is its "AI-Native" design. Moving away from general-purpose colocation architecture, Sesterce has engineered this campus specifically for dense GPU clusters (supporting NVIDIA Blackwell and subsequent architectures). The facility features integrated hybrid liquid cooling, allowing for rack densities that far exceed traditional European standards. This design is critical for the "AI Supercycle" of 2026, where inference and training workloads require unprecedented thermal management.

The investment of €18 billion is backed by a powerful consortium and supported by the French state’s "France 2030" initiative, which aims to secure digital sovereignty. By placing the campus in the Rhône-Alpes region, Sesterce capitalizes on the proximity to major nuclear power plants, ensuring a reliable, high-voltage power supply that is 95% carbon-free. This makes it one of the most sustainable mega-projects globally, targeting a PUE of 1.12.

Beyond the hardware, the campus is a catalyst for regional economic transformation. It is expected to create over 3,500 high-tech jobs and reinforce Lyon’s position as a premier European data hub, rivaling the traditional FLAP-D (Frankfurt, London, Amsterdam, Paris, Dublin) markets. With Phase 1 scheduled for a late 2026 go-live, the Sesterce Rhône-Alps campus is poised to become the primary engine for European AI research, sovereign cloud hosting, and large-scale enterprise automation.
