On May 13, 2024, the Federal Energy Regulatory Commission (FERC) released Order 1920, a landmark rulemaking requiring each of the transmission planning regions in the United States to undergo long-term transmission planning. The rulemaking also contains important reforms to local transmission oversight and interregional coordination.

To assist stakeholders with better understanding the rule, RMI has put together the following downloadable fact sheet providing a high-level summary of the rule and, in partnership with other organizations, a flowchart summarizing the FERC-proposed timeline for the planning process. The fact sheet has also been updated to reflect amendments made by FERC in Order 1920-A (issued November 21, 2024).
