Microsoft Commits $10 Billion to AI Data Hub in Sines, Portugal

Subsea cable access plus planned clean energy make Sines central to Microsoft’s European AI expansion.

Overview

  • Microsoft will develop the site over the next few years at Start Campus’s data‑center park about 150 kilometers south of Lisbon.
  • The project teams Microsoft with Start Campus, Nscale and NVIDIA to deploy 12,600 next‑generation NVIDIA GPUs.
  • Sines was selected for transatlantic subsea cable routes and a pipeline of renewable‑energy projects intended to power energy‑intensive facilities.
  • Start Campus separately plans €8.5 billion of investment through 2030 at the campus, with one of six planned buildings already in operation.
  • Microsoft also signed a multi‑year capacity lease at Sines in October, reinforcing a broader European AI infrastructure expansion driven by surging demand for accelerator compute since 2022.
