On June 18, 2026, the Federal Energy Regulatory Commission (FERC) issued show cause orders to six FERC-jurisdictional regional transmission organizations and system operators (RTOs) to further advance the integration of data centers and other large loads in the interstate electric transmission grid. The orders represent FERC’s first substantive action in response to the October 2025 rulemaking request from the U.S. Department of Energy seeking to expedite the interconnection of data centers to the interstate transmission grid.
