Five-Year Review of the Oil Pipeline Index
Summary
The Federal Energy Regulatory Commission issued its five-year review of the Oil Pipeline Index, updating the rate-indexing methodology for oil pipelines operating under FERC jurisdiction. The order, filed and issued on April 24, 2026, carries docket number RM26-6-000 and includes a regulatory impact analysis. Affected oil pipeline companies should review the revised index parameters to determine the impact on their tariff filings and rate-recovery mechanisms.
Oil pipelines subject to FERC's indexing methodology should track the specific index adjustments in this review — the ceiling-rate formula directly affects the maximum rates that can be charged for pipeline transportation service. Companies with pending rate cases or those planning tariff updates in the near term should align those filings with the revised index parameters once effective.

What changed
The Commission conducted its required five-year review of the Oil Pipeline Index methodology, potentially adjusting the index factors used to calculate ceiling rates for oil pipeline transportation. This review fulfills FERC's statutory obligation under the Interstate Commerce Act to examine whether the existing index remains appropriate.
Oil pipeline operators should closely review the revised index values and compare them against current ceiling rates to assess whether tariff adjustments are warranted. Pipeline companies that file indexed rates will need to ensure their next tariff filings reflect the updated index parameters.
