Status: Announced / Active Expansion (Investment committed late 2025) | Location: Saint-Ghislain, Hainaut Province, Belgium
???????? Project Overview: Google Saint-Ghislain Expansion
The announcement of an additional €5 Billion (US$5.5 Billion) investment by Google in its Saint-Ghislain data center campus across 2026-2027 is a powerful commitment to anchoring the company's AI and cloud backbone in Europe. This expansion, one of the largest digital economy investments in Belgium's history, is fundamentally driven by the enormous computational demands of new technologies like the Gemini AI models and the general surge in cloud services across the European market.
Saint-Ghislain, which has been Google's first European data center site since 2007, will be substantially enlarged, adding 300 full-time jobs and solidifying its role as a key regional hub for Google Cloud's services across its global network of 42 regions. This provides the high-performance, low-latency compute required by regional businesses, including major entities like Odoo and UZ Leuven.
Critically, the investment is inextricably linked to sustainability mandates and the European Green Deal. Google is simultaneously expanding its carbon-free energy agreements in Belgium, including deals with providers like Eneco, Luminus, and Renner for over 110 MW of new wind and solar capacity. This strategy not only meets the site's escalating energy demands but also contributes to Google's ambitious goal of running on 24/7 Carbon-Free Energy (CFE) by 2030. The facility continues to champion efficiency with its use of advanced free cooling technology, which leverages Belgium's climate to minimize water consumption and achieve industry-leading low PUE (Power Usage Effectiveness), reinforcing the trend of integrating massive infrastructure growth with direct renewable energy procurement.
The expansion is viewed by Belgian and Walloon authorities as a strategic move that enhances national digital sovereignty and economic growth, with estimates projecting the total investment to generate over €1.5 billion annually in GDP and support nearly 15,000 jobs by 2027, making it a powerful catalyst for the region's digital and energy transition.
