Google has announced a €5 billion investment to expand its data centre infrastructure in Belgium, a move that underlines both the speed and scale of the artificial intelligence (AI) revolution reshaping Europe’s digital economy. The expansion, centred on the company’s St. Ghislain campus in Wallonia, will add 300 new full-time jobs and further integrate AI into Europe’s critical digital backbone.
The investment will be rolled out over two years, from 2026 to 2027, and marks one of the largest single technology infrastructure commitments ever made in Belgium. It will enhance Google Cloud’s AI capabilities while supporting the growing computational needs of billions of users of Search, Maps, and Workspace. For Europe, it signals the deepening intersection between AI infrastructure, industrial policy, and energy transition strategy.
Belgium’s Prime Minister Bart De Wever called the investment “a powerful sign of trust in Belgium as a hub for digital innovation and sustainable growth”, while emphasising its strategic importance to Europe’s long-term digital independence.
Building Europe’s AI backbone
Google’s expansion in Belgium is not simply a story of data capacity. It represents a structural shift in how AI is being embedded into Europe’s industrial landscape. As the continent seeks to balance technological sovereignty with the need for global collaboration, investments like this play a critical role in ensuring access to high-performance compute, the raw infrastructure driving AI model development, training, and deployment.
Once completed, the expanded St. Ghislain facility will strengthen Google Cloud’s Belgian region, one of 42 global hubs that deliver the low-latency, high-performance computing demanded by modern AI applications. These facilities underpin workloads from healthcare and manufacturing to financial services and scientific research.
Pierre-Yves Jeholet, Vice-President of the Government of Wallonia, said the project confirms Wallonia’s “central role as a European hub for data processing and storage”, adding that it supports regional digital sovereignty while fostering AI skills and innovation.
A 2024 study commissioned by Google estimated that widespread adoption of generative AI could boost Belgium’s GDP by €45–50 billion over the next decade. According to research by Université de Mons and Deloitte, Google’s historical data centre investments have already contributed €697 million to GDP between 2022 and 2024, with a forecast of €1.5 billion annually from 2026 onwards.
AI’s growing energy footprint
As AI scales, so too does its energy consumption, and that challenge is at the core of Google’s plan. The company’s data centres are among the most energy-efficient in the world, but the computational load of AI requires a new approach to sustainability. To that end, Google announced 110 megawatts (MW) of new carbon-free energy agreements with Eneco, Luminus, and Renner, contributing to its goal of operating on 24/7 carbon-free energy across every grid where it runs.
This adds to Google’s cumulative 365 MW of clean energy commitments in Belgium and forms part of a wider European portfolio totalling over 4.5 gigawatts of renewable generation capacity. The company is also working with Centrica Energy and Elia, Belgium’s transmission system operator, to integrate battery storage and demand response systems, allowing flexible load balancing to support grid resilience.
At a local level, Google is tackling another critical sustainability issue: water use. Through a partnership with Shayp, it is deploying IoT leak detection in 240 non-residential buildings near St. Ghislain, targeting a 120% water replenishment rate by 2030. This initiative could save an estimated 500 cubic metres of water per year, directly benefiting local institutions such as schools and universities.
AI, jobs, and the human factor
AI-driven automation often sparks fears of job losses, but the St. Ghislain expansion tells a more nuanced story. The facility already employs around 600 people in technical, engineering, and operational roles. The new investment will increase that number to 900, alongside thousands of indirect roles supported through supply chains and construction.
The initiative also extends beyond infrastructure to address the AI skills gap. Through Google.org, the company is funding non-profits to deliver free AI and digital skills training across Belgium, targeting workers looking to transition careers or upskill in an AI-driven economy.
Bikash Koley, Vice President of Google Global Infrastructure, said the investment “deepens Google’s roots in Belgium” and ensures that “people across Belgium and Europe have access to opportunity in this exciting era of innovation.”
A statement of intent for Europe’s AI future
In a continent increasingly defined by its race to build AI capacity, Google’s €5 billion expansion is as much a statement of intent as an investment. It positions Belgium as a key node in the infrastructure supporting Europe’s digital sovereignty while demonstrating that AI and sustainability must evolve together.
The convergence of compute power, clean energy, and human capital in St. Ghislain offers a blueprint for how Europe can compete in the global AI economy, one grounded not only in technology, but in the long-term balance between intelligence, innovation, and environmental responsibility.
