Now Here You Go Again – FERC Prepares to Slash the Liquids Pipeline Rate Index

By May 16, 2025No Comments

On Thursday, June 18, the Federal Energy Regulatory Commission (FERC) issued a Notice of Inquiry (NOI) to reset the index that’s used to make annual changes to the rate ceilings for interstate pipelines that transport crude oil, refined products, and other hydrocarbon liquids. Every year, the highest rate an indexed oil pipeline can charge goes up or down — almost always up — using the FERC index. The commission’s new proposal, which would become effective in July 2021, follows an already-approved index adjustment that will take effect a week from Wednesday, on July 1. Taken together, the two changes would reduce the maximum annual increase in the rate ceiling from more than 4% now to less than 1%, which could have a major impact on liquids pipeline owners. Today, we discuss the NOI, the meaning of the pipeline index, where it came from, and where it might be headed.
