Aluminum Co. of America v. Central Lincoln Peoples' Utility District
Headline: Power allocation ruling reverses appeals court and lets the BPA Administrator set interruptibility terms, allowing industrial customers the same kilowatts while reducing nonfirm power available to public utilities.
Holding: The Court reversed the Ninth Circuit, holding that the BPA Administrator's interpretation of the Regional Act was reasonable and that the statute required offering DSIs the same quantity of power (kilowatts), not identical interruptibility terms.
- Allows BPA to offer DSIs same kilowatt amounts with different interruption rules.
- Reduces nonfirm federal power available for preference (public) utilities.
- Gives the agency broad discretion in negotiating power contracts and rates.
Summary
Background
The dispute involves the Bonneville Power Administration (BPA), large industrial customers that buy power directly (called DSIs), and public utility customers that get priority for federal power. Under 1975 contracts, a top 25% slice of DSI power could be interrupted "at any time," giving public utilities access to that nonfirm power. Congress passed the 1980 Regional Act requiring BPA to offer new long-term contracts that provide each DSI the same amount of power as in 1975. The BPA Administrator offered contracts keeping the same kilowatt amounts but changing when interruptions could occur, and preference customers sued. A federal appeals court struck down the contracts, and the case reached the Supreme Court.
Reasoning
The Court asked whether the statute required identical interruptibility or only the same quantity of power. It gave deference to the agency’s interpretation because BPA has technical expertise and helped draft the law. The Court held that "amount of power" refers to quantity (kilowatts) rather than exact interruption terms, and that the initial contracts mandated by Congress are not the same as uncommitted power subject to administrative preference. The Court found the Administrator’s construction reasonable and lawful, reversed the Court of Appeals, and sent the case back for further proceedings consistent with that view.
Real world impact
Practically, the decision lets BPA keep the same numerical power commitments to DSIs while changing when interruptions may occur to protect firm loads. That reduces the pool of nonfirm power available to public utilities and confirms BPA’s discretion to set contract terms tied to financing an exchange program and setting rates. The case was reversed and remanded, so further steps in lower courts will follow.
Dissents or concurrances
Justice Stevens dissented, arguing the phrase "amount of power" should include the interruptibility that determined how much power DSIs actually received under the 1975 contracts, and that the new terms unlawfully gave DSIs more assured power than Congress intended.
