According to reporting from Wired, the U.S. Energy Information Agency (EIA) has informed two U.S. senators that it plans to introduce a new rule requiring all domestic data centers to share detailed records of their energy consumption with the federal government.

This official commitment comes roughly one month after Senators Josh Hawley and Elizabeth Warren sent a formal letter to the EIA, calling on the agency to start systematic data collection on the data center sector. The lawmakers’ request was intended to push the agency to formalize oversight of an industry whose total energy demand has grown rapidly and consistently in recent years.

Per Wired’s account, the eventual nationwide data collection effort will be mandatory for all covered operators. The EIA has not yet announced a final launch date for the new reporting questionnaire.

The agency first announced plans for an initial pilot survey back in March, which targeted 196 companies across three key regions: Texas, the state of Washington, and the Washington D.C.-Northern Virginia metropolitan area. It followed that announcement in April, confirming plans for a second separate pilot survey across three additional U.S. states. EIA chief Tristan Abbey projects that both pilot programs will wrap up by September. Once the trial programs are completed, the agency will begin developing the final version of the mandatory nationwide survey that will cover all data centers across the country.
