Discover. Analyze. Understand Impact.

A data center is a purpose-built facility that houses servers, storage, and networking equipment used to run applications, host websites, and store data at scale. Modern facilities range from small edge sites to hyperscale campuses drawing hundreds of megawatts of power.

For every facility we track location (city, state/region, country), operator, operational status (active, planned, or under construction), and power capacity in megawatts where disclosed or reasonably estimable — all shown on the interactive map and in the crawlable facility list on this page.

Capacity is expressed in megawatts (MW) of IT power — the electrical load available to run servers and cooling, distinct from a facility's physical square footage. We label figures as disclosed (from public/operator sources) or AI-estimated when no public figure exists, and we never blend the two without stating the split.

"Active" facilities are operational today. "Under construction" facilities are physically being built. "Planned" facilities have been announced or permitted but have not yet broken ground. All three statuses are shown on the map and in the facility table so you can see the full pipeline, not just what's live.

Yes — the directory, map, and rankings on Data Center List are free and publicly accessible. We source and estimate data to keep it as accurate and current as possible, and clearly note when a figure is estimated rather than disclosed.
