New Mexico has imposed an energy tax on the privilege of
generating electricity within the State. This tax applies to all
utility companies generating electricity within the State and may
be credited against the New Mexico gross receipts tax liability for
electricity sold at retail within New Mexico. But where the
electricity is transmitted to other States for sale and
consumption, there is no gross receipts tax liability against which
to offset energy tax liability. A federal statute, 15 U.S.C. §
391, prohibits a State from imposing a tax on the generation or
transmission of electricity which discriminates against
out-of-state consumers, and further provides that a tax is
discriminatory if it "results, either directly or indirectly, in a
greater tax burden on electricity" generated and transmitted in
interstate commerce than on electricity generated and transmitted
in intrastate commerce. Appellant utility companies, owners of New
Mexico power plants at which most of the electricity generated is
ultimately sold to out-of-state consumers, brought action in a New
Mexico state court seeking to have the energy tax invalidated on
the ground,
inter alia, that it violated the federal
statute, but the New Mexico Supreme Court, affirming the trial
court, upheld the tax.
Held: The New Mexico energy tax is invalid under the
Supremacy Clause by reason of the federal statute. Because the tax
itself, through operation of the tax-credit provisions, indirectly
but necessarily discriminates against electricity sold outside New
Mexico, it violates that statute. The federal statute does not
exceed the permissible bounds of congressional action under the
Commerce Clause, since Congress had a rational basis for finding
that a tax such as New Mexico's interfered with interstate
commerce, and selected a reasonable method to eliminate that
interference. Pp. 146-151.

MR JUSTICE STEWART delivered the opinion of the Court.
New Mexico has imposed a tax on the privilege of generating
electricity within its borders. The question in this case is
whether that tax conflicts with federal law, statutory or
constitutional.
I
The Four Corners power plants, located in New Mexico's desert
northwest, are owned by the appellants, five public utilities
companies. [
Footnote 1] Most of
the electricity generated at the plants is ultimately sold to
out-of-state consumers. [
Footnote
2] New
Page 441 U. S. 143
Mexico imposes a 4% gross receipts tax on retail sellers of
electricity, [
Footnote 3] but
since the bulk of the appellants' sales are made to consumers in
other States, they do not incur significant liability for this tax.
In 1975, New Mexico enacted the Electrical Energy Tax Act, the law
at issue in this case. [
Footnote
4] That Act imposes a tax on the privilege of generating
electricity at the rate of 4/10 of a mill on each net kilowatt hour
of electricity generated. This is roughly equivalent to a 2% tax on
the retail value of the electricity. The tax is imposed on all
companies generating electricity within the State. Section 9 of the
Act, however, provides that this electrical energy tax may be fully
credited against the company's gross receipts tax liability.
The Act and the regulations implementing it insure that the
electrical generating company will receive full credit for the
Page 441 U. S. 144
tax even if it does not itself make retail sales of electricity.
This result is accomplished by requiring the generating company to
assign its "potential credit" to the retailer, who, in turn, is
required to reimburse the generating company for the value of this
credit. [
Footnote 5] The
consequence is that a generating
Page 441 U. S. 145
company's 2% tax is completely offset by the credit against the
4% retail sales tax when its electricity is sold within New Mexico.
But to the extent that the electricity generated in New Mexico is
not sold at retail in the State, there is no gross receipts tax
liability against which to offset the electrical energy tax
liability of the generating company.
In 1976, the State of Arizona, as a consumer of electricity and
parens patriae for its citizens, sought to invoke this
Court's original jurisdiction by a motion for leave to file a bill
of complaint against New Mexico, asking for a declaratory judgment
invalidating this New Mexico tax. The litigation now before us had
already been initiated in the New Mexico courts by the present
appellants, seeking essentially the same relief. This Court denied
Arizona leave to file its complaint, concluding:
"[T]he pending state court action provides an appropriate forum
in which the issues tendered here may be litigated. If, on appeal,
the New Mexico Supreme Court should hold the electrical energy tax
unconstitutional, Arizona will have been vindicated. If, on the
other hand, the tax is held to be constitutional, the issues raised
now may be brought to this Court by way of direct appeal under 28
U.S.C. § 1257(2)."
Arizona v. New Mexico, 425 U.
S. 794,
425 U. S.
797.
One of the alternative scenarios foreseen in our 1976 opinion
has now eventuated. The New Mexico Supreme Court has upheld the
validity of this energy tax against federal statutory and
constitutional attacks,
Arizona Public Serv. Co. v.
O'Chesky, 91 N.M. 485,
576 P.2d
291, and the issues have been brought to this Court by way of
direct appeal under 28 U.S.C. § 1257(2). 439 U.S. 891.
Page 441 U. S. 146
II
The appellants contend that the New Mexico tax is invalid under
a specific federal statute as well as under the Commerce, Due
Process, and Import-Export Clauses of the Constitution. Because we
conclude that, under the Supremacy Clause, [
Footnote 6] the tax is invalid by reason of this
federal statute, we do not reach the substantive constitutional
issues.
When Congress enacted the Tax Reform Act of 1976, it included a
provision relating to state taxes on electricity. Section 2121(a)
of the Act, 90 Stat.1914, codified at 15 U.S.C. § 391,
provides:
"No State, or political subdivision thereof, may impose or
assess a tax on or with respect to the generation or transmission
of electricity which discriminates against out-of-State
manufacturers, producers, wholesalers, retailers, or consumers of
that electricity. For purposes of this section, a tax is
discriminatory if it results, either directly or indirectly, in a
greater tax burden on electricity which is generated and
transmitted in interstate commerce than on electricity which is
generated and transmitted in intrastate commerce."
This provision was not in the bill as passed by the House of
Representatives. Its genesis was in the Senate Finance Committee,
although in its original version the definition of a discriminatory
tax was different from that in the law finally enacted:
"For purposes of this section a tax is discriminatory that
either directly or indirectly results in the payment of a higher
gross or net tax on electricity which is generated and transmitted
in interstate commerce than on electricity
Page 441 U. S. 147
which is generated and transmitted in intrastate commerce."
H.R. 10612, 94th Cong., 1st Sess., § 1323 (1976) .
The Committee's Report described the reasons for including the
provision:
"The committee has learned that one State places a
discriminatory tax upon the production of electricity within its
boundaries for consumption outside its boundaries. While the rate
of the tax itself is identical for electricity that is ultimately
consumed outside the State and electricity which is consumed inside
the State, discrimination results, because the State allows the
amount of the tax to be credited against its gross receipts tax if
the electricity is consumed within its boundaries. This credit
normally benefits only domiciliaries of the taxing State, since no
credit is allowed for electricity produced within the State and
consumed outside the State. As a result, the cost of the
electricity to nondomiciliaries is normally increased by the cost
the producer of the electricity must bear in paying the tax.
However, the cost to domiciliaries of the taxing State does not
include the amount of the tax."
"The committee believes that this is an example of
discriminatory State taxation which is properly within the ability
of Congress to prohibit through its power to regulate interstate
commerce."
(Footnote omitted.) S.Rep. No. 94 938, pt. I, pp. 43738
(1976).
The identity of the unnamed State was disclosed during the
course of a subsequent Senate floor debate on a motion by Senator
Domenici of New Mexico to strike the provision from the bill.
Senators Domenici and Montoya of New Mexico, Senators Fannin and
Goldwater of Arizona, and Senator Cranston of California made it
clear that the provision was aimed directly at New Mexico's
electrical energy tax. 122
Page 441 U. S. 148
Cong.Rec. 24324-24329 (1976). At the conclusion of this debate,
Senator Domenici's motion to eliminate the provision was defeated.
Id. at 24329.
The appellees concede that this statutory provision was aimed
directly at the New Mexico Electrical Energy Tax Act. They contend,
however, that the definition of a discriminatory tax was so defused
in the Conference Committee that Congress, in the law as enacted,
failed to hit its mark. Specifically, they point out that a
discriminatory tax, defined in the Senate Committee's original
draft as one that results in "the payment of a higher gross or net
tax," became, in the statute as enacted, one which results in "a
greater tax burden" on electricity transmitted out of state than
that sold within the State.
We are told that the statutory definition was redrafted in the
Conference Committee to allay the concerns of Senators from States
with somewhat similar taxes. That Committee's Report gave no
reason, however, for the change in language. The Report merely
stated:
"
Senate amendment. -- Under present law, any
restrictions on the power of States or their political subdivisions
to tax goods or services produced in the taxing State for
nondomiciliary use outside the taxing State are derived from court
interpretations of the interstate commerce clause of the
Constitution."
"The Senate amendment prohibits any State or political
subdivision of a State from directly or indirectly imposing any tax
on the generation or transmission of electricity which
discriminates against out-of-State users. This provision is
effective for taxable years beginning after June 30, 1974."
"
Conference agreement. -- The conference agreement
follows the Senate amendment."
H.R.Conf.Rep. No. 94-1515, p. 503 (1976).
There is thus no legislative history to show what the Conference
Committee's drafting change was intended to accomplish.
Page 441 U. S. 149
But the provision as enacted is far from the "sterile"
legislation that the appellees contend it is. To the contrary, the
provision clearly operates, we think, to carry out the expressed
intent of the Senate to invalidate the New Mexico tax.
The Act prohibits "a tax on or with respect to the generation or
transmission of electricity" which "results, either directly or
indirectly, in a greater tax burden on electricity" consumed
outside of New Mexico than that consumed in the State. The
appellees urge that this statutory provision is no more than a
prohibition of a tax that is invalid under the constitutional test
of the Commerce Clause. That test, they say, requires examination
of New Mexico's total tax structure to determine whether the State,
in fact, imposes a greater tax burden on electricity sent out of
state.
See Halliburton Oil Well Cementing Co. v. Reily,
373 U. S. 64,
373 U. S. 69.
And the tax in question, they say, clearly survives such an
examination. Power sold within New Mexico, they argue, is subject
to a 4% tax: 2% from the electrical energy tax and 2% from the
gross receipts tax. By contrast, New Mexico subjects electricity
sent out of state only to its 2% generation tax. The appellees
contend, therefore, that, if there is any discrimination in New
Mexico's taxing structure, it is discrimination against electricity
consumed within the State.
But, whatever the validity may be of the Commerce Clause test
advanced by the appellees, the federal statutory provision is
directed specifically at a state tax "on or with respect to the
generation or transmission of electricity," not to the entire tax
structure of the State. The tax imposed by New Mexico's Electrical
Energy Tax Act is concededly a tax on the generation of
electricity. The tax credit provisions of the Act itself insure
that locally consumed electricity is subject to no tax burden from
the electrical energy tax, while the bulk of the electricity
generated in New Mexico by the appellants is subject to a 2% tax,
since it is sold outside the State. To look
Page 441 U. S. 150
narrowly to the type of tax the federal statute names, rather
than to consider the entire tax structure of the State, is to be
faithful not only to the language of that statute, but also to the
expressed intent of Congress in enacting it. Because the electrical
energy tax itself indirectly but necessarily discriminates against
electricity sold outside New Mexico, it violates the federal
statute. [
Footnote 7]
The appellees also argue that, if the federal statute is
construed to invalidate the New Mexico tax, it exceeds the
permissible bounds of congressional action under the Commerce
Clause. In view of the broad power of Congress to regulate
interstate commerce, this argument must be rejected.
See
Wickard v. Filburn, 317 U. S. 111;
Katzenbach v. McClung, 379 U. S. 294.
Here, the Congress had a rational basis for finding that the New
Mexico tax interfered with interstate commerce, and selected a
reasonable method to eliminate that interference. The legislation,
thus, was within the constitutional power of Congress to enact.
See Heart of Atlanta Motel, Inc. v. United States,
379 U. S. 241,
379 U. S.
258-259;
United States v. Wrightwood Dairy Co.,
315 U. S. 110,
315 U. S.
119.
The generation of electricity in the Four Corners region
undoubtedly also generates environmental and other problems for New
Mexico. There is no indication that Congress intended to prevent
the State from taxing the generation of
Page 441 U. S. 151
electricity to pay for solutions to these problems. But the
generation of electricity to be sent to Phoenix causes no more
problems than the generation of electricity to be sent to
Albuquerque. Congress required only that New Mexico, if it chooses
to tax the generation of electricity for consumption in either
city, tax it equally for each.
The judgment is reversed.
It so ordered.
[
Footnote 1]
The five appellants are Arizona Public Service Co., El Paso
Electric Co., Salt River Project Agricultural Improvement &
Power Dist., Southern California Edison Co., and Tucson Gas &
Electric Co. Each appellant owns an undivided interest in the Four
Corners Power Plant. Tucson Gas & Electric is an equal co-owner
with Public Service Co. of New Mexico of units of the San Juan
Generating Station. El Paso Electric Co. owns and operates the Rio
Grande Generating Station in southern New Mexico.
[
Footnote 2]
Arizona Public Service Co. makes some minor retail sales of
electricity in New Mexico. El Paso Electric makes retail sales in a
significant portion of southern New Mexico, and is the only one of
the appellants regulated by New Mexico as a public utility. El Paso
Electric also sells electricity at wholesale in the Republic of
Mexico. In 1975, the five appellants generated nearly a billion
kilowatt hours of electricity in New Mexico.

Footnote 4]
The critical sections of the Electrical Energy Tax Act are
§§ 3 and 9. They provide in relevant part as follows:
Section 3.
"A. For the privilege of generating electricity in this state
for the purpose of sale, whether the sale takes place in this state
or outside this state, there is imposed on any person generating
electricity a temporary tax, applicable until July 1, 1984, of
four-tenths of one mill ($.0004) on each net kilowatt hour of
electricity generated in New Mexico."
"B. The tax imposed by this section shall be referred to as the
'electrical energy tax.'"
N.M.Stat.Ann. § 7-18 3 (1978).
Section 9.
"B. On electricity generated inside this state and consumed in
this state which was subject to the electrical energy tax, the
amount of such tax paid may be credited against the gross receipts
tax due this state."
"C. The credit under Subsections A or B of this section shall be
assigned to the person selling the electricity for consumption in
New Mexico on which New Mexico gross receipts tax is due, and the
assignee shall reimburse the assignor for the credit."
N.M.Stat.Ann. § 7-9-80 (1978).
[
Footnote 5]
The relevant sections of the regulations provide:
"B. Section 72-16A-16.1(C) [now codified as § 7-9-80(C)]
requires that a potential credit be assigned to persons purchasing
electricity for resale:"
"1) to buyers who will potentially consume or use the
electricity in New Mexico, or"
"2) to buyers who will potentially resell the electricity for
consumption in New Mexico; on which an electrical energy tax or
similar tax has been levied by New Mexico, by another state or by
political subdivisions thereof and paid by the seller."
"Each seller of electricity as described in this paragraph must
assign, to each buyer described in subparagraphs (1) and (2) of
this paragraph, a pro-rata share of the total available potential
credit provided in Section 72-16A-16.1(A) or (b) [now codified as
§§ 7-9-80(A), 7-9-80(b)]."
"C. It shall be presumed that the potential credit against gross
receipts tax as provided by Section 72-16A-16.1(C) shall have been
assigned when the buyer is in receipt of an invoice from the seller
separately stating the amount of the applicable Electrical Energy
Tax or similar tax as provided in Section 72-16A-16.1."
"In the absence of bad faith, a wholesale purchaser in New
Mexico of electricity may rely upon such an invoice in claiming a
credit under Section 72-16A-16.1."
"D."
"1) That portion of the potential credit assigned to a buyer
further reselling the electricity for consumption in New Mexico may
be credited by the assignee against the gross receipts tax due New
Mexico on receipts from the sale of electricity for any month
subsequent to July 1, 1975."
"2) That portion of the potential credit assigned to a buyer
further reselling the electricity at wholesale to buyers who will
resell the electricity for consumption in New Mexico must be
reassigned to the subsequent buyer as provided in paragraph B of
this regulation."
"3) That amount of the electric energy tax credit which is not
assigned to appropriate buyers and which is otherwise creditable
under Section 72-16A-16.1, may be credited against the gross
receipts tax due New Mexico on receipts from the sale of
electricity for any reporting month subsequent to July 1,
1975."

[
Footnote 7]
This is not a case where the State has imposed an evenhanded tax
on the generation of electricity and has lowered the gross receipts
or sales tax on the sale of electricity. Although New Mexico argues
that such is the practical result of its tax structure, the credit
provisions of the Electrical Energy Tax Act itself shift the legal
incidence of the gross receipts tax credit directly to the
generating utility.
The
amici in this case have pointed to several similar
state taxes on the generation of electricity. Pa.Stat.Ann., Tit.
72, § 8101 (Purdon Supp. 1978-1979); Wash.Rev.Code
§§ 82.16.020, 82.16.050 (1976); W.Va.Code §§
11-13-2d 11-13-2m (Supp. 1978). None of the States, however, has
adopted precisely the scheme used by New Mexico, and we express no
opinion as to the validity of these or any other state tax
laws.
MR. JUSTICE REHNQUIST, with whom MR. JUSTICE WHITE joins,
concurring in the judgment.
I concur in the judgment of the Court because I agree that the
tax imposed by New Mexico's Electrical Energy Tax Act on the
generation of electricity within its borders is forbidden by §
2121(a) of the Tax Reform Act of 1976, codified at 15 U.S.C. §
391.
I think that the statutory question is somewhat closer than the
Court intimates, both as to the meaning of the actual language of
§ 391 and as to its legislative history. As the Court
indicates, and as appellees concede, the debate on the floor of the
Senate makes it clear that the original version of § 391 was
aimed at New Mexico's energy tax.
See ante at
441 U. S.
147-148; Brief for Appellees 14. New Mexico argues here
that the original provision was redrafted in conference in order to
"save" somewhat similar tax statutes in other States, and that, as
redrafted, § 391 is "sterile" legislation: it accomplishes no
more than the Commerce Clause of the Constitution would accomplish
of its own force.
See ante at
441 U. S. 149;
Brief for Appellees 11, 16, 24. Congress is vested with the
legislative power of the United States, and not the judicial power,
and therefore it may be unrealistic to assume automatically that
Congress never passes a "sterile" law, in the sense that the
provision does no more than the Constitution would have done had
Congress never enacted the law. But, in my view, the laws enacted
by Congress certainly are entitled to a presumption
Page 441 U. S. 152
to that effect. Since the effect of § 391 is not entirely
clear from its language and legislative history, I would give some
weight to that presumption in reaching the conclusion that §
391 extends beyond the requirements of the Commerce Clause
* and outlaws the
New Mexico energy tax here at issue.
* There is no question in my mind that, if § 391 were
coextensive with the Commerce Clause, New Mexico's energy tax would
be valid for substantially the same reasons advanced by appellees.
