Case Facts & Court Holding
Key Facts & Case Background
Northwest Pipeline Corp. operated an interstate natural gas pipeline. Its tariff, Section 14.8, established a formula for a Fuel Reimbursement Percentage (FRP) charged to its “unbundled” transportation customers. The formula required dividing the “total annual fuel” by the “total annual volumes … transported through Transporter’s transmission system.” For years, Northwest calculated the FRP by dividing total fuel costs by only the volumes transported for unbundled customers, excluding volumes for its “bundled” customers. This methodology resulted in a higher charge for unbundled customers. In 1991, Northwest submitted its annual FRP adjustment using this same calculation. A customer, Northwest Natural, protested the filing. The Federal Energy Regulatory Commission (FERC) accepted the new rate but suspended it and made it “subject to refund” pending review, a procedure under § 4 of the Natural Gas Act (NGA). Upon review, FERC agreed with the protest, finding that Northwest’s calculation violated the plain language of its own tariff. FERC ordered Northwest to recalculate the FRP using the total transported volume (both bundled and unbundled) in the denominator and to refund the resulting overcharges to unbundled customers, retroactive to the filing’s effective date. Northwest appealed, arguing the order was impermissible retroactive ratemaking.
