In plain language

The bill requires studies before foreign companies can build data centers in Illinois.

This legislation, called the Data Center Construction by Foreign Adversaries Act, mandates joint studies on energy consumption by the Illinois Commerce Commission, the Illinois Power Agency, and the Department of Commerce and Economic Opportunity. Only after certification that the data center's energy usage is self-generated and does not impact regional energy supplies can foreign companies proceed with construction.

Summary

Creates the Data Center Construction by Foreign Adversaries Act. Provides that no foreign company may construct or cause to be constructed a data center in the State unless the Illinois Commerce Commission, the Illinois Power Agency, and the Department of Commerce and Economic Opportunity conduct a joint study of the energy consumption of the prospective data center and certify to the Governor and the General Assembly that the energy used by the new data center is a new self-generated load and does not affect the load supply of PJM or MISO. Provides that the term "foreign company" means an entity that (i) is at least 51% owned by a foreign adversary or (ii) is headquartered in a country with a government that is a foreign adversary.
