Our European pipeline tracker follows 4 data-centre projects of 1 MW or more that Eclairion develops or co-develops, in 1 country; 1 is permitted or already being built. All of them are in France.

25% are permitted or being built, against 44% across the whole tracker, so the pipeline is earlier-stage than the European average. The milestones we hold run from Nov 2025 to May 2026.
