FERC v. Electric Power Supply Assn.
The Supreme Court ruled that the Federal Energy Regulatory Commission has authority to require wholesale electricity market operators to pay consumers the same price for reducing power use as they pay power plants for producing it, rejecting the argument that the rule illegally reached into states' control over retail electricity sales.
The decision preserves a federal program that pays businesses and aggregators to cut electricity use during high-demand periods, a tool regulators and Congress had championed as a way to lower wholesale prices and prevent grid failures.
How it got here: The D.C. Circuit vacated FERC's rule as exceeding its authority and, alternatively, as arbitrary and capricious; FERC and demand-response companies asked the Supreme Court to review that ruling.
The Case in Depth
What happened
Electric grid operators run wholesale auctions where power plants bid to supply electricity and are all paid the price of the highest accepted bid. To fight rising prices and grid strain during peak demand, operators let large electricity users and aggregators bid to get paid for using less power instead. FERC ordered operators to pay these "demand response" providers the same price as power plants, and an industry trade group sued, arguing FERC was illegally regulating retail electricity sales reserved to the states.
The question before the Court
Could the federal government regulate how the electric grid pays consumers for agreeing to use less power at peak times, or was that a state-only retail matter?
Why it matters
Businesses, aggregators, and large electricity users that get paid to cut power use during peak demand can keep participating in these federally regulated wholesale programs. Electric grid operators retain a tool to lower wholesale prices and avoid blackouts during heat waves and other high-demand periods, without states being able to claim the program illegally interferes with retail electricity markets.
What changes now
The case returns to the D.C. Circuit for further proceedings consistent with the Supreme Court's ruling, which reinstates FERC's authority to regulate demand response compensation and upholds the specific compensation formula it chose. This is a final decision on the merits, not a temporary order, and the wholesale demand response program can continue operating as designed, subject to any further individualized challenges on remand.
What this does not decide
The Court did not decide that FERC can regulate any practice merely touching retail electricity; it emphasized that its holding rests on the rule operating entirely within the wholesale market and being justified solely by wholesale market goals. States retain the ability to bar their own consumers from participating in these wholesale demand response programs.
Concurrences and dissents
Dissent — Justice Scalia
Justice Scalia argued the Federal Power Act's plain terms bar FERC from regulating any sale that isn't a wholesale sale (a sale for resale), and demand response participants consume electricity themselves rather than reselling it, so the rule was unauthorized regardless of its effect on wholesale rates. He also argued the rule in fact directly regulates retail sales by effectively raising the price retail customers pay for electricity through forgone incentive payments. He would have held the rule unlawful without reaching whether it was arbitrary and capricious.
How the Court got there
The legal reasoning, step by step
- The Court first asked whether the disputed practice — how demand response bids are compensated — directly affects wholesale electricity rates, adopting a 'direct effect' standard to keep the agency's power over anything 'affecting' wholesale rates from expanding without limit.
- Applying that standard, the Court found demand response programs and their compensation formulas plainly meet it, because paying more for demand response bids draws in more such bids, which displaces higher-priced power plant bids and directly lowers the wholesale price.
- The Court then asked whether the rule nonetheless crossed into regulating retail sales, which the Federal Power Act reserves exclusively to the states. It held that a federal rule does not violate that reservation merely because it has spillover effects on retail prices or consumption, since wholesale and retail markets are inherently linked.
- Because every mechanism of the rule — the bidding, the payment, the parties responsible for payment — operated entirely within the wholesale market and was justified solely by wholesale market goals, the Court concluded the rule did not regulate retail sales.
- The Court added that reading the statute to bar the rule would leave demand response unregulated by anyone, since the industry group agreed states also lacked power over these wholesale transactions — an outcome inconsistent with the law's purpose of ensuring effective, comprehensive electricity regulation.
- Turning to whether the chosen compensation method was arbitrary and capricious, the Court applied a deferential standard asking only whether the agency examined the relevant considerations and offered a reasoned explanation, and found the agency's detailed, responsive explanation for treating power-saving and power-producing bids equally satisfied that standard.
