AI data center sites

Search sites, programs and supporting energy records by location, company, status or capacity.

1,114 public records · About catalogue coverage

Search property-level records across markets, participants, capacity, development activity, infrastructure and supporting evidence.

1,043 site records69 program records2 energy assets / agreements1,105 detailed profiles9 sourced research records

Record types partition the public catalogue; detailed and sourced-research labels describe those same records, not additional sites. Site records are not a deduplicated count of physical campuses. Overlapping campus, phase or tenant scopes must not be added together.

Capacity stages and scopes differ; do not add figures together. How to compare

19 of 30 matching records have an eligible headline. Select both basis and stage for a like-for-like view. Bounds, physical scope and reporting dates still differ; this is not an additive capacity total.
