Land near a high-voltage line is not a connectable site. To compare sites before costly studies, you need a consistent reading and, above all, to know what is confirmed, estimated or unknown.
DOES YOUR SITUATION LOOK LIKE ONE OF THESE?
I own 20 ha of land near a 400 kV line. Is it worth anything for a data center?Our 12 ha plot is in an AU zone of the local land-use plan (PLU). Can we build a 60 MW data center on it?The primary substation 4 km away shows capacity, but Enedis mentions reinforcement. Is 12 MW at MV (HTA) realistic?

Each site gets a readiness score built on explicit criteria with its confidence level. It helps rank and compare; it does not guarantee a connection. See land assessment and site checklist.
FREQUENTLY ASKED QUESTIONS
Does a readiness score guarantee grid connection?
No. It helps compare and prioritise. Connection and its date are decided by the grid operator.
