Mobil Oil Corp. v. Federal Power Commission
Headline: Area pricing for Southern Louisiana natural gas is upheld, allowing new price ceilings, a $150 million refund plan, moratoria, and supply-linked price increases that reshape producer and pipeline economics.
Holding: The Court affirmed the appeals court’s approval of the Federal Power Commission’s 1971 Southern Louisiana area rate order, including price ceilings, a $150 million refund plan, moratoria, and supply-linked escalations, finding statutory authority and substantial evidence supported it.
- Allows higher area price ceilings and supply-linked escalations to boost producer revenues.
- Caps historical refunds at an agreed $150 million instead of larger earlier estimates.
- Imposes moratoria on producer rate filings through 1976–1977, limiting immediate rate challenges.
Summary
Background
A federal agency (the Federal Power Commission) spent a decade creating an area price plan for natural gas produced in southern Louisiana and the nearby Gulf, an area that the opinion says supplies about one-third of the Nation’s domestic gas. Major industry and consumer interests — including a large producer (Mobil), a state utility commission (New York), and a municipal distributors group — challenged the agency’s 1971 order after an earlier 1968 order and appeals-court proceedings. The agency reopened and consolidated proceedings, compiled thousands of pages of evidence, and adopted a broad settlement-supported rate structure and refund plan.
Reasoning
The core question was whether the agency had statutory authority and enough evidence to adopt the 1971 area rate order and its features: price ceilings for flowing and new gas, a $150 million aggregated refund obligation, moratoria on new producer rate filings, contingent price escalations tied to new reserves, and changes in how certain gas is priced. The Court applied prior guidance that gives heavy deference to the agency’s technical judgments. It concluded the agency could reopen earlier orders, consider a nonunanimous settlement on the merits, and that the record provided substantial evidence to support the rates and the incentive features aimed at increasing supply. Challenges that the rates were too high, too low, or unlawfully discriminatory were rejected.
Real world impact
The decision lets the agency’s 1971 plan operate: specific ceiling rates and supply-linked escalators become effective, refunds are capped at the agreed $150 million figure, and moratoria on certain rate filings remain in place into the mid-1970s. The ruling leaves regulator-designed incentives and compromises in place to encourage more exploration and to balance producer, pipeline, and consumer interests. Two Justices did not participate in the decision.
