on writs of certiorari to the united states
court of appeals for the fourth circuit
[April 19, 2016]
Justice Ginsburg delivered the opinion of the
Court.
The Federal Power Act (FPA), 41Stat. 1063, as
amended, 16 U. S. C. §791a
et seq., vests in
the Federal Energy Regulatory Commission (FERC) exclusive
jurisdiction over wholesale sales of electricity in the interstate
market. FERC’s regulatory scheme includes an auction-based market
mechanism to ensure wholesale rates that are just and reasonable.
FERC’s scheme, in Maryland’s view, provided insufficient incentive
for new electricity generation in the State. Maryland therefore
enacted its own regulatory program. Maryland’s program provides
subsidies, through state-mandated contracts, to a new generator,
but conditions receipt of those subsidies on the new generator
selling capacity into a FERC-regulated wholesale auction. In a suit
initiated by competitors of Maryland’s new electricity generator,
the Court of Appeals for the Fourth Circuit held that Maryland’s
scheme impermissibly intrudes upon the wholesale electricity
market, a domain Congress reserved to FERC alone. We affirm the
Fourth Circuit’s judgment.
I
A
Under the FPA, FERC has exclusive authority to
regulate “the sale of electric energy at wholesale in interstate
commerce.” §824(b)(1). A wholesale sale is defined as a “sale of
electric energy to any person for resale.” §824(d). The FPA assigns
to FERC responsibility for ensuring that “[a]ll rates and charges
made, demanded, or received by any public utility for or in
connection with the transmission or sale of electric energy subject
to the jurisdiction of the Commission . . . shall be just
and reasonable.” §824d(a). See also §824e(a) (if a rate or charge
is found to be unjust or unreasonable, “the Commission shall
determine the just and reasonable rate”). “But the law places
beyond FERC’s power, and leaves to the States alone, the regulation
of ‘any other sale’—most notably, any retail sale—of electricity.”

The States’ reserved authority includes control over in-state
“facilities used for the generation of electric energy.”

State
Energy Resources Conservation and Development Comm’n, 461
U. S. 190, 205 (1983) (“Need for new power facilities, their
economic feasibility, and rates and services, are areas that have
been characteristically governed by the States.”).
“Since the FPA’s passage, electricity has
increasingly become a competitive interstate business, and FERC’s
role has evolved accordingly.”
EPSA, 577 U. S., at ___
(slip op., at 4). Until relatively recently, most state energy
markets were vertically integrated monopolies—
i.e., one
entity, often a state utility, controlled electricity generation,
transmission, and sale to retail consumers. Over the past few
decades, many States, including Maryland, have deregulated their
energy markets. In deregulated markets, the organizations that
deliver electricity to retail consumers—often called “load serving
entities” (LSEs)—purchase that electricity at wholesale from
independent power generators. To ensure reliable transmission of
electricity from independent generators to LSEs, FERC has charged
nonprofit entities, called Regional Transmission Organizations
(RTOs) and Independent System Operators (ISOs), with managing
certain segments of the electricity grid.
Interstate wholesale transactions in deregulated
markets typically occur through two mechanisms. The first is
bilateral contracting: LSEs sign agreements with generators to
purchase a certain amount of electricity at a certain rate over a
certain period of time. After the parties have agreed to contract
terms, FERC may review the rate for reasonableness. See
Morgan
Stanley Capital Group Inc. v.
Public Util. Dist. No. 1 of
Snohomish Cty., 554 U. S. 527 –548 (2008) (Because rates
set through good-faith arm’s-length negotiation are presumed
reasonable, “FERC may abrogate a valid contract only if it harms
the public interest.”). Second, RTOs and ISOs administer a number
of competitive wholesale auctions: for example, a “same-day
auction” for immediate delivery of electricity to LSEs facing a
sudden spike in demand; a “next-day auction” to satisfy LSEs’
anticipated near-term demand; and a “capacity auction” to ensure
the availability of an adequate supply of power at some point far
in the future.
These cases involve the capacity auction
administered by PJM Interconnection (PJM), an RTO that oversees the
electricity grid in all or parts of 13 mid-Atlantic and Midwestern
States and the District of Columbia. The PJM capacity auction
functions as follows. PJM predicts electricity demand three years
ahead of time, and assigns a share of that demand to each
participating LSE. Owners of capacity to produce electricity in
three years’ time bid to sell that capacity to PJM at proposed
rates. PJM accepts bids, beginning with the lowest proposed rate,
until it has purchased enough capacity to satisfy projected demand.
No matter what rate they listed in their original bids, all
accepted capacity sellers receive the highest accepted rate, which
is called the “clearing price.”[
1] LSEs then must purchase from PJM, at the clearing
price, enough electricity to satisfy their PJM-assigned share of
overall projected demand. The capacity auction serves to identify
need for new generation: A high clearing price in the capacity
auction encourages new generators to enter the market, increasing
supply and thereby lowering the clearing price in same-day and
next-day auctions three years’ hence; a low clearing price
discourages new entry and encourages retirement of existing
high-cost generators.[
2]
The auction is designed to accommodate long-term
bilateral contracts for capacity. If an LSE has acquired a certain
amount of capacity through a long-term bilateral contract with a
generator, the LSE—not the generator—is considered the owner of
that capacity for purposes of the auction. The LSE sells that
capacity into the auction, where it counts toward the LSE’s
assigned share of PJM-projected demand, thereby reducing the net
costs of the LSE’s required capacity purchases from PJM.[
3] LSEs generally bid their capacity
into the auction at a price of $0, thus guaranteeing that the
capacity will clear at any price. Such bidders are called “price
takers.” Because the fixed costs of building generating facilities
often vastly exceed the variable costs of producing electricity,
many generators also function as price takers.
FERC extensively regulates the structure of the
PJM capacity auction to ensure that it efficiently balances supply
and demand, producing a just and reasonable clearing price. See
EPSA, 577 U. S., at ___ (slip op., at 5) (the clearing
price is “the price an efficient market would produce”). Two FERC
rules are particularly relevant to these cases. First, the Minimum
Offer Price Rule (MOPR) requires new generators to bid capacity
into the auction at or above a price specified by PJM, unless those
generators can prove that their actual costs fall below the MOPR
price. Once a new generator clears the auction at the MOPR price,
PJM deems that generator an efficient entrant and exempts it from
the MOPR going forward, allowing it to bid its capacity into the
auction at any price it elects, including $0. Second, the New Entry
Price Adjustment (NEPA) guarantees new generators, under certain
circumstances, a stable capacity price for their first three years
in the market. The NEPA’s guarantee eliminates, for three years,
the risk that the new generator’s entry into the auction might so
decrease the clearing price as to prevent that generator from
recovering its costs.
B
Around 2009, Maryland electricity regulators
became concerned that the PJM capacity auction was failing to
encourage development of sufficient new in-state generation.
Because Maryland sits in a particularly congested part of the PJM
grid, importing electricity from other parts of the grid into the
State is often difficult. To address this perceived supply
shortfall, Maryland regulators proposed that FERC extend the
duration of the NEPA from three years to ten. FERC rejected the
proposal.
PJM, 126 FERC ¶62,563 (2009). “[G]iving new
suppliers longer payments and assurances unavailable to existing
suppliers,” FERC reasoned, would improperly favor new generation
over existing generation, throwing the auction’s market-based
price-setting mechanism out of balance.
Ibid. See also
PJM, 128 FERC ¶61,789 (2009) (order on petition for
rehearing) (“Both new entry and retention of existing efficient
capacity are necessary to ensure reliability and both should
receive the same price so that the price signals are not skewed in
favor of new entry.”).
Shortly after FERC rejected Maryland’s NEPA
proposal, the Maryland Public Service Commission promulgated the
Generation Order at issue here. Under the order, Maryland solicited
proposals from various companies for construction of a new
gas-fired power plant at a particular location, and accepted the
proposal of petitioner CPV Maryland, LLC (CPV). Maryland then
required LSEs to enter into a 20-year pricing contract (the parties
refer to this contract as a “contract for differences”) with CPV at
a rate CPV specified in its accepted proposal.[
4] Unlike a traditional bilateral contract for
capacity, the contract for differences does not transfer ownership
of capacity from CPV to the LSEs. Instead, CPV sells its capacity
on the PJM market, but Maryland’s program guarantees CPV the
contract price rather than the auction clearing price.
If CPV’s capacity clears the PJM capacity
auction and the clearing price falls below the price guaranteed in
the contract for differences, Maryland LSEs pay CPV the difference
between the contract price and the clearing price. The LSEs then
pass the costs of these required payments along to Maryland
consumers in the form of higher retail prices. If CPV’s capacity
clears the auction and the clearing price exceeds the price
guaranteed in the contract for differences, CPV pays the LSEs the
difference between the contract price and the clearing price, and
the LSEs then pass the savings along to consumers in the form of
lower retail prices. Because CPV sells its capacity exclusively in
the PJM auction market, CPV receives no payment from Maryland LSEs
or PJM if its capacity fails to clear the auction. But CPV is
guaranteed a certain rate if its capacity does clear, so the
contract’s terms encourage CPV to bid its capacity into the auction
at the lowest possible price.[
5]
Prior to enactment of the Maryland program, PJM
had exempted new state-supported generation from the MOPR, allowing
such generation to bid capacity into the auction at $0 without
first clearing at the MOPR price. Responding to a complaint filed
by incumbent generators in the Maryland region who objected to
Maryland’s program (and the similar New Jersey program), FERC
eliminated this exemption.
PJM, 135 FERC ¶61,106 (2011). See
also 137 FERC ¶61,145 (2011) (order on petition for rehearing)
(“Our intent is not to pass judgment on state and local policies
and objectives with regard to the development of new capacity
resources, or unreasonably interfere with those objectives. We are
forced to act, however, when subsidized entry supported by one
state’s or locality’s policies has the effect of disrupting the
competitive price signals that PJM’s [capacity auction] is designed
to produce, and that PJM as a whole, including other states, rely
on to attract sufficient capacity.”);
New Jersey Bd. of Pub.
Util. v.
FERC, 744 F. 3d 74, 79–80 (CA3 2014)
(upholding FERC’s elimination of the state-supported generation
exemption). In the first year CPV bid capacity from its new plant
into the PJM capacity auction, that capacity cleared the auction at
the MOPR rate, so CPV was thereafter eligible to function as a
price taker.
In addition to seeking the elimination of the
state-supported generation exemption, incumbent
generators—respondents here—brought suit in the District of
Maryland against members of the Maryland Public Service Commission
in their official capacities. The incumbent generators sought a
declaratory judgment that Maryland’s program violates the Supremacy
Clause by setting a wholesale rate for electricity and by
interfering with FERC’s capacity-auction policies.[
6] CPV intervened as a defendant. After a
six-day bench trial, the District Court issued a declaratory
judgment holding that Maryland’s program improperly sets the rate
CPV receives for interstate wholesale capacity sales to PJM.
PPL
Energyplus, LLC v.
Nazarian, 974 F. Supp. 2d 790,
840 (Md. 2013). “While Maryland may retain traditional state
authority to regulate the development, location, and type of power
plants within its borders,” the District Court explained, “the
scope of Maryland’s power is necessarily limited by FERC’s
exclusive authority to set wholesale energy and capacity prices.”
Id., at 829.[
7]
The Fourth Circuit affirmed. Relying on this
Court’s decision in
Mississippi Power & Light Co. v.
Mississippi ex rel. Moore, 487 U. S. 354, 370 (1988) ,
the Fourth Circuit observed that state laws are preempted when they
“den[y] full effect to the rates set by FERC, even though [they do]
not seek to tamper with the actual terms of an interstate
transaction.”
PPL EnergyPlus, LLC v.
Nazarian, 753
F. 3d 467, 476 (2014). Maryland’s program, the Fourth Circuit
reasoned, “functionally sets the rate that CPV receives for its
sales in the PJM auction,” “a FERC-approved market mechanism.”
Id., at 476–477. “[B]y adopting terms and prices set by
Maryland, not those sanctioned by FERC,” the Fourth Circuit
concluded, Maryland’s program “strikes at the heart of the agency’s
statutory power.”
Id., at 478.[
8] The Fourth Circuit cautioned that it “need not express
an opinion on other state efforts to encourage new generation, such
as direct subsidies or tax rebates, that may or may not differ in
important ways from the Maryland initiative.”
Ibid.
The Fourth Circuit then held that Maryland’s
program impermissibly conflicts with FERC policies. Maryland’s
program, the Fourth Circuit determined, “has the potential to
seriously distort the PJM auction’s price signals,” undermining the
incentive structure FERC has approved for construction of new
generation.
Ibid. Moreover, the Fourth Circuit explained,
Maryland’s program “conflicts with NEPA” by providing a 20-year
price guarantee to a new entrant—even though FERC refused
Maryland’s request to extend the duration of the NEPA past three
years.
Id., at 479.
We granted certiorari, 577 U. S. ___
(2015), and now affirm.
II
The Supremacy Clause makes the laws of the
United States “the supreme Law of the Land; . . . any
Thing in the Constitution or Laws of any State to the Contrary
notwithstanding.” U. S. Const., Art. VI, cl. 2. Put
simply, federal law preempts contrary state law. “Our inquiry into
the scope of a [federal] statute’s pre-emptive effect is guided by
the rule that the purpose of Congress is the ultimate touchstone in
every pre-emption case.”
Altria Group, Inc. v.
Good,
555 U. S. 70, 76 (2008) (internal quotation marks omitted). A
state law is preempted where “Congress has legislated
comprehensively to occupy an entire field of regulation, leaving no
room for the States to supplement federal law,”
Northwest
Central Pipeline Corp. v.
State Corporation Comm’n of
Kan., 489 U. S. 493, 509 (1989) , as well as “where, under
the circumstances of a particular case, the challenged state law
stands as an obstacle to the accomplishment and execution of the
full purposes and objectives of Congress,”
Crosby v.
National Foreign Trade Council, 530 U. S. 363, 373
(2000) (brackets and internal quotation marks omitted).
We agree with the Fourth Circuit’s judgment that
Maryland’s program sets an interstate wholesale rate, contravening
the FPA’s division of authority between state and federal
regulators. As earlier recounted, see
supra, at 2, the FPA
allocates to FERC exclusive jurisdiction over “rates and charges
. . . received . . . for or in connection with”
interstate wholesale sales. §824d(a). Exercising this authority,
FERC has approved the PJM capacity auction as the sole ratesetting
mechanism for sales of capacity to PJM, and has deemed the clearing
price
per se just and reasonable. Doubting FERC’s
judgment, Maryland—through the contract for differences—requires
CPV to participate in the PJM capacity auction, but guarantees CPV
a rate distinct from the clearing price for its interstate sales of
capacity to PJM. By adjusting an interstate wholesale rate,
Maryland’s program invades FERC’s regulatory turf. See
EPSA,
577 U. S., at ___ (slip op., at 26) (“The FPA leaves no room
either for direct state regulation of the prices of interstate
wholesales or for regulation that would indirectly achieve the same
result.” (internal quotation marks omitted)).[
9]
That Maryland was attempting to encourage
construction of new in-state generation does not save its program.
States, of course, may regulate within the domain Congress assigned
to them even when their laws incidentally affect areas within
FERC’s domain. See
Oneok, Inc. v.
Learjet, Inc., 575
U. S. ___, ___ (2015) (slip op., at 11) (whether the Natural
Gas Act (NGA) preempts a particular state law turns on “the
target at which the state law
aims”).[
10] But States may not seek to achieve
ends, however legitimate, through regulatory means that intrude on
FERC’s authority over interstate wholesale rates, as Maryland has
done here. See
ibid. (distinguishing between “measures
aimed directly at interstate purchasers and wholesalers for
resale, and those aimed at subjects left to the States to regulate”
(internal quotation marks omitted)).[
11]
The problem we have identified with Maryland’s
program mirrors the problems we identified in
Mississippi Power
& Light and
Nantahala Power & Light Co. v.
Thornburg, 476 U. S. 953 (1986) . In each of those
cases, a State determined that FERC had failed to ensure the
reasonableness of a wholesale rate, and the State therefore
prevented a utility from recovering—through retail rates—the full
cost of wholesale purchases. See
Mississippi Power &
Light, 487 U. S., at 360–364;
Nantahala, 476
U. S., at 956–962. This Court invalidated the States’ attempts
to second-guess the reasonableness of interstate wholesale rates.
“ ‘Once FERC sets such a rate,’ ” we observed in
Mississippi Power & Light, “ ‘a State may not
conclude in setting retail rates that the FERC-approved wholesale
rates are unreasonable. A State must rather give effect to
Congress’ desire to give FERC plenary authority over interstate
wholesale rates, and to ensure that the States do not interfere
with this authority.’ ” 487 U. S., at 373 (quoting
Nantahala, 476 U. S., at 966). True, Maryland’s program
does not prevent a utility from recovering through retail sales a
cost FERC mandated it incur—Maryland instead guarantees CPV a
certain rate for capacity sales to PJM regardless of the clearing
price. But
Mississippi Power & Light and
Nantahala make clear that States interfere with FERC’s
authority by disregarding interstate wholesale rates FERC has
deemed just and reasonable, even when States exercise their
traditional authority over retail rates or, as here, in-state
generation.
The contract for differences, Maryland and CPV
respond, is indistinguishable from traditional bilateral contracts
for capacity, which FERC has long accommodated in the auction. See
supra, at 4–5, and n. 3. But the contract at issue here
differs from traditional bilateral contracts in this significant
respect: The contract for differences does not transfer ownership
of capacity from one party to another outside the auction. Instead,
the contract for differences operates within the auction; it
mandates that LSEs and CPV exchange money based on the cost of
CPV’s capacity sales to PJM. Notably, because the contract for
differences does not contemplate the sale of capacity outside the
auction, Maryland and CPV took the position, until the Fourth
Circuit issued its decision, that the rate in the contract for
differences is not subject to FERC’s reasonableness review. See
§824(b)(1) (FERC has jurisdiction over contracts for “
the sale
of electric energy at wholesale in interstate commerce.”
(emphasis added)).[
12]
Our holding is limited: We reject Maryland’s
program only because it disregards an interstate wholesale rate
required by FERC. We therefore need not and do not address the
permissibility of various other measures States might employ to
encourage development of new or clean generation, including tax
incentives, land grants, direct subsidies, construction of
state-owned generation facilities, or re-regulation of the energy
sector. Nothing in this opinion should be read to foreclose
Maryland and other States from encouraging production of new or
clean generation through measures “untethered to a generator’s
wholesale market participation.” Brief for Respondents 40. So long
as a State does not condition payment of funds on capacity clearing
the auction, the State’s program would not suffer from the fatal
defect that renders Maryland’s program unacceptable.[
