What does it take to build Europe’s largest and most sustainable data-centre campus, from an empty plot of land to a 1.2-gigawatt giant of AI? How do you future-proof a facility when chip technology is evolving at breakneck speed? And what happens when the site of former coal-fired power plant becomes a global hub for AI?

In this special, on-location episode of Cleaning Up, Michael Liebreich visits Sines, Portugal, where Start Campus is transforming the site of a decommissioned coal plant into a next-generation data-centre campus that once finished will be Europe’s largest data centre.

CEO Robert Dunn takes us inside the first operational building, currently 29MW but just 2.5% of what’s to come, to explore the engineering, economics, and vision behind a €10 billion physical infrastructure build that will eventually house an additional €40 billion in incoming IT hardware.

From earthquake-proof structures to seawater cooling and uninterruptible power supply systems, Rob breaks down what it means to design for 99.99999% uptime in an AI-driven world. Michael and Rob also dive into the reality and hype surrounding AI: the surge in GPU-hungry AI training, the race to build at gigawatt scale, the challenges of financing these mega-projects, and the balancing act between speed, cost, sustainability, and long-term viability.

Set against the backdrop of Microsoft’s freshly announced $10 billion investment in the Sines campus, this episode illuminates how the data-centre industry is reshaping global energy systems, local communities, and the future of compute.
