What changed
FERC issued a Notice of Extension of Time for the electric regional transmission planning and cost allocation rulemaking (RM21-17). The notice extends the procedural timeline for this ongoing rulemaking without changing the substantive requirements being developed. Regional transmission organizations, utilities, and transmission developers should anticipate that the final rule will arrive later than originally anticipated and should continue monitoring FERC for revised schedules.
The extension is administrative in nature and does not alter the scope or requirements under consideration. Stakeholders who have been preparing comments or compliance plans should continue their regulatory engagement efforts while adjusting internal timelines to account for the delayed rulemaking schedule.
What to do next
- Monitor for updates on revised comment deadlines for RM21-17
