Me. Justice Minton
delivered the opinion of the Court.
This is an appeal from the affirmance of an order of the Michigan Public Service Commission requiring appellant to obtain a certificate of public convenience and necessity before selling natural gas direct to industrial consumers in a municipality already served by a public utility.
Appellant is engaged in the transportation of natural gas by pipe line from fields in Texas, Oklahoma and Kansas into areas which include the State of Michigan. Appellant is a “natural-gas company” within the coverage of the Natural Gas Act, 52 Stat. 821, 15 U. S. C. §§ 717 et seg., and subject thereunder to regulation by the Federal Power Commission. Appellee Michigan Consolidated Gas Company is a public utility of Michigan which under appropriate authorization distributes gas to domestic, commercial and industrial consumers in and around Detroit. Consolidated obtains its entire supply of natural gas for distribution in the Detroit district from appellant.
In 1945 appellant publicly announced a program of securing large industrial customers for the direct sale of natural gas in Michigan. In Detroit it offered to pay the City for the right to lay and operate its pipe line along the streets and alleys directly to large industrial customers. In October of that year appellant succeeded in securing a large direct-sale contract with the Ford Motor Company for gas at its Dearborn plant, located in the Detroit district. Ford was already purchasing substantial quantities of gas for industrial use at the Dearborn plant from Consolidated.
Believing its interests and those of its customers were prejudiced by appellant’s program, particularly the Ford contract, Consolidated filed a complaint with the Michigan Public Service Commission. Appellant appeared to contest the jurisdiction of the Commission over such sales. After hearing, the Commission ordered appellant to—
“cease and desist from making direct sales and deliveries of natural gas to industries within the State of Michigan, located within municipalities already being served by a public utility, until such time as it shall have first obtained a certificate of public convenience and necessity from this Commission to perform such services.”
Appellant obtained an injunction against the order of the Commission in the Circuit Court of Ingham County, Michigan. The Circuit Court held that the order was a prohibition of interstate commerce and therefore invalid. The Supreme Court of Michigan, three judges dissenting, reversed the Circuit Court and affirmed the Commission’s order. 328 Mich. 650, 44 N. W. 2d 324. That court rejected the argument that the order of the Commission was an absolute denial of the right of appellant to sell natural gas in Michigan direct to consumers. Since appellant was free to make application to the Michigan Commission for a certificate of public convenience and necessity as to such sales, the order was construed as denying the right of appellant to sell direct without first obtaining such certificate. The court held this requirement to be within the State’s regulatory authority despite the interstate character of the sales. This appeal challenges the correctness of that decision.
The sale to industrial consumers as proposed by appellant is clearly interstate commerce. Panhandle Pipe Line Co. v. Public Service Comm’n of Indiana, 332 U. S. 507, 513; Pennsylvania Gas Co. v. Commission, 252 U. S. 23, 28. But the sale and distribution of gas to local consumers made by one engaged in interstate commerce is “essentially local” in aspect and is subject to state regulation without infringement of the Commerce Clause of the Federal Constitution. In the absence of federal regulation, state regulation is required in the public interest. Pennsylvania Gas Co. v. Commission, supra, at 31. See also opinion of Cardozo, J., in Pennsylvania Gas Co. v. Commission, 225 N. Y. 397, 122 N. E. 260. These principles apply to direct sales for industrial consumption as well as to sales for domestic and commercial uses. Panhandle-Indiana, supra, at 514, 519-520.
The facts in the instant case show that the proposed sales are primarily of local interest. They emphasize the need for local regulation and the wisdom of the principles just discussed. To accommodate its operations, appellant proposes to use the streets and alleys of Detroit and environs. A local utility already operating in the same area, Consolidated, receives its entire supply of natural gas from appellant. A substantial portion of Consolidated’s revenues is derived from sales to large industrial consumers. Appellant ignored requests of Consolidated for additional gas to meet the increased wants of its industrial customers. Instead of attempting to meet increased needs through Consolidated, appellant launched a program to secure for itself large industrial accounts from customers, some of whom were already being served by Consolidated. In connection with the Ford Motor Company, it is noteworthy that the tap line by which appellant proposed to serve Ford directly would be substantially parallel to and only a short distance from the existing tap line by which Consolidated now serves Ford.
Thus, not only would there be two utilities using local facilities to accommodate their distribution systems, but they would be seeking to serve the same industrial consumers. Appellant asserts a right to compete for the cream of the volume business without regard to the local public convenience or necessity. Were appellant successful in this venture, it would no doubt be reflected adversely in Consolidated’s over-all' costs of service and its rates to customers whose only source of supply is Consolidated. This clearly presents a situation of “essentially local” concern and of vital interest to the State of Michigan.
Of course, when Congress acts in this field it is supreme. It has acted. Section 1 (b) of the Natural Gas Act, supra, provides as follows:
“The provisions of this Act shall apply to the transportation of natural gas in interstate commerce, to the sale in interstate commerce of natural gas for resale for ultimate public consumption for domestic, commercial, industrial, or any other use, and to natural-gas companies engaged in such transportation or sale, but shall not apply to any other transportation or sale of natural gas or to the local distribution of natural gas or to the facilities used for such distribution or to the production or gathering of natural gas.”
By this Act Congress occupied only a part of the field. As to sales, only the sale of gas in interstate commerce for resale was covered. Direct sales for consumptive use were designedly left to state regulation. Panhandle-Indiana, 332 U. S. at 516-518. Speaking further of the division of regulatory authority over interstate commerce in natural gas, this Court said in the same case:
“It would be an exceedingly incongruous result if a statute so motivated, designed and shaped to bring about more effective regulation, and particularly more effective state regulation, were construed in the teeth of those objects, and the import of its wording as well, to cut down regulatory power and to do so in a manner making the states less capable of regulation than before the statute’s adoption. Yet this, in effect, is what appellant asks us to do. For the essence of its position, apart from standing directly on the commerce clause, is that Congress by enacting the Natural Gas Act has ‘occupied the field,’ i e., the entire field open to federal regulation, and thus has relieved its direct industrial sales of any subordination to state control.
“The exact opposite is the fact. Congress, it is true, occupied a field. But it was meticulous to take in only territory which this Court had held the states could not reach. That area did not include direct consumer sales, whether for industrial or other uses. Those sales had been regulated by the states and the regulation had been repeatedly sustained. In no instance reaching this Court had it been stricken down.
“The Natural Gas Act created an articulate legislative program based on a clear recognition of the respective responsibilities of the federal and state regulatory agencies. It does not contemplate ineffective regulation at either level. We have emphasized repeatedly that Congress meant to create a comprehensive and effective regulatory scheme, complementary in its operation to those of the states and in no manner usurping their authority. . . . And, as was pointed out in Power Comm’n v. Hope Gas Co., [320 U. S. 591] at 610, ‘the primary aim of this legislation was to protect consumers against exploitation at the hands of natural gas companies.’ The scheme was one of cooperative action between federal and state agencies. It could accomplish neither that protective aim nor the comprehensive and effective dual regulation Congress had in mind, if those companies could divert at will all or the cream of their business to unregulated industrial uses.” 332 U. S. at 519, 520-521.
The statutory scheme of “dual regulation” might have some overlaps or conflicts but no such exigencies appear here. There are no opposing directives and hence no necessity for us to resolve any conflicting claims as between state and federal regulation.
Appellant concedes, as it must, that direct sales by it to industrial consumers are subject to state rate regulation under the Panhandle-Indiana decision. It contends, however, that that decision does not comprehend its problem, reasoning that the jurisdiction here asserted by the Michigan Commission is the power to prohibit interstate commerce in natural gas.
Although the end result might be prohibition of particular direct sales, to require appellant to secure a certificate of public convenience and necessity before it may enter a municipality already served by a public utility is regulation, not absolute prohibition. There is no intimation that appellant cannot deliver and sell available gas to Consolidated for resale to customers who have additional gas requirements. It is no discrimination against interstate commerce for Michigan to require appellant to route its sales of gas through the existing certificated utility where the public convenience and necessity would not be served by direct sales. That there is neither discrimination nor prohibition here saves this regulation from the rule of such cases as Hood & Sons v. Du Mond, 336 U. S. 525, relied on by appellant, where a state was said to have discriminated against interstate commerce by prohibiting it because it would subject local business to competition. And the statute under which the Michigan Commission acted does not distinguish between an interstate or intrastate agency desiring to operate in a locality already served by a utility. See Cities Service Co. v. Peerless Co., 340 U. S. 179, 188.
It does not follow that because appellant is engaged in interstate commerce it is free from state regulation or free to manage essentially local aspects of its business as it pleases. The course of this Court’s decisions recognizes no such license. See Cities Service case, supra; Panhandle-Indiana case, supra; Pennsylvania Gas Co. v. Commission, 252 U. S. 23. Such a course would not accomplish the effective dual regulation Congress intended, and would permit appellant to prejudice substantial local interests. This is not compelled by the Natural Gas Act or the Commerce Clause of the Constitution.
Judgment affirmed.
The Commission acted under authority of Mich. Comp. Laws, 1948, § 460.502, which provides:
“Sec. 2. No public utility shall hereafter begin the construction or operation of any public utility plant or system thereof nor shall it render any service for the purpose of transacting or carrying on a local business either directly, or indirectly, by serving any other utility or agency so engaged in such local business, in any municipality in this state where any other utility or agency is then engaged in such local business and rendering the same sort of service, or where such municipality is receiving service of the same sort, until such public utility shall first obtain from the commission a certificate that public convenience and necessity requires or will require such construction, operation, service, or extension.”
Other relevant sections of the Michigan statute provide:
“Sec. 3. Before any such certificate of convenience and necessity shall issue, the applicant therefor shall file a petition with the commission stating the name of the municipality or municipalities which it desires to serve and the kind of service which it proposes to render, and that the applicant has secured the necessary consent or franchise from such municipality or municipalities authorizing it to transact a local business.” § 460.503.
“Sec. 5. In determining the question of public convenience and necessity the commission shall take into consideration the service being rendered by the utility then serving such territory, the investment in such utility, the benefit, if any, to the public in the matter of rates and such other matters as shall be proper and equitable in determining whether or not public convenience and necessity requires the applying utility to serve the territory. ...” § 460.505.
