State and local registry records in Illinois

Each row is a state or local government record that names a data-center facility or project. DataCenterData selected factual fields and cites the agency page. It does not republish the database. A certification, tax status, air permit, or application does not establish that a data center is operating, its capacity, or who owns or operates it. The list is not a census and is not added to licensed rows, operator-listed sites, federal registry records, or reviewed records.
