FERC v. Electric Power Supply Assn.
The Court ruled that federal energy regulators can 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 this improperly reaches into the retail electricity market reserved for the states.
The decision preserves a federal program that pays big energy users and aggregators to cut consumption during peak demand, which regulators say lowers wholesale prices and reduces the risk of blackouts.
How it got here: The D.C. Circuit vacated the rule as beyond FERC's authority and, alternatively, as arbitrary and capricious; FERC and other parties asked the Supreme Court to review.
The Case in Depth
What happened
Wholesale electricity markets pay power plants for producing electricity and, under a "demand response" program, also pay large consumers and aggregators for agreeing to cut their electricity use during peak hours. A federal rule required market operators to pay demand response providers the same price as generators. Electric suppliers challenged the rule, arguing it improperly regulated retail electricity sales, which by law belong to the states.
The question before the Court
Could federal regulators require wholesale electricity markets to pay consumers the same price for cutting power use as they pay power plants for generating it?
Why it matters
Businesses and aggregators that get paid to curb electricity use during high-demand periods can keep participating in these federal wholesale programs, which regulators say lower everyone's power costs and reduce blackout risk. States retain the power to block their own retail customers from taking part, preserving some state control over the practice.
What changes now
The case is sent back to the D.C. Circuit for further proceedings consistent with the Court's ruling, meaning the demand-response compensation rule can go back into effect. This is a final merits decision, not a temporary order, so the wholesale demand response program can continue nationwide, subject to any individual state's choice to bar its own retail customers from participating.
What this does not decide
The Court did not decide whether paying demand response providers the same price as generators (rather than a reduced amount) is the best policy — only that FERC adequately explained and justified that choice. It also left states free to block their own retail customers from participating in these wholesale programs.
Concurrences and dissents
Dissent — Justice Scalia
“To repeat: take the energy, be $15 poorer; forgo the energy, be $15 richer. Is that not the very definition of price?”Scalia's argument that incentive payments effectively set a retail price for electricity.
Justice Scalia argued that the Federal Power Act asks only whether a transaction is a wholesale sale (a sale for resale), and since demand-response participants consume electricity themselves rather than reselling it, the rule regulates non-wholesale transactions FERC has no power over. He also argued that even under the majority's framing, the rule regulates retail sales because incentive payments raise the effective retail price of electricity. He would have held the rule entirely unauthorized and found no need to reach the arbitrary-and-capricious question.
How the Court got there
The legal reasoning, step by step
- The Court first asked whether the demand-response rule directly affects wholesale electricity rates, since federal law lets regulators oversee not just wholesale prices themselves but any rule or practice that directly affects them (as opposed to merely having some indirect or remote connection).
- Because paying consumers to cut usage displaces higher-priced power generation and thereby lowers the price set in wholesale auctions, the Court found the compensation rule for demand response squarely meets that direct-effect standard.
- The Court then asked whether the rule crosses into regulating retail sales, which only states may control. It held that a wholesale rule does not violate that limit merely because it has spillover effects on retail markets, since wholesale and retail markets are inherently linked and wholesale regulation inevitably touches retail levels somewhat.
- The Court rejected the argument that offering payments not to buy retail power is the same as setting an 'effective' retail price, reasoning that a price is what is actually charged and received in a transaction, not the value of a forgone opportunity.
- Because every element of the rule operates through the wholesale auction process and is aimed at improving wholesale market functioning, not retail pricing, the Court concluded the rule stays within the wholesale side of the line Congress drew.
- The Court also reasoned that reading the law to bar both federal and state regulation of demand response would create a regulatory void inconsistent with the law's purpose of comprehensively controlling electricity markets to keep prices reasonable and service reliable.

Reaffirms California Independent System Operator Corp. v. FERC (372 F. 3d 395)
The Court adopted this lower-court decision's standard limiting FERC's jurisdiction to practices that directly affect wholesale rates.
Reaffirms Mississippi Power & Light Co. v. Mississippi ex rel. Moore (487 U. S. 354)
The Court relied on this case to show that wholesale regulation affecting retail prices does not exceed FERC's authority.
