Since 1913, Missouri has required public utilities conducting business in the State to receive prior approval from the Missouri Public Service Commission before purchasing stocks or bonds issued by another utility. See Mo.Rev.Stat. § 393.190.2. In this case, Southern Union Company applied to the Commission for blanket approval to make non-controlling investments in utilities that do not operate in Missouri. Following an evidentiary hearing, the Commission denied the application, concluding that it may not grant blanket approvals, and alternatively that the approval sought would be detrimental to the public interest. Southern Union then filed this action against the Commission and individual Commissioners under 42 U.S.C. § 1983, seeking a declaratory judgment that § 393.190.2 violates the Commerce Clause and impermissibly conflicts with federal statutes. The district court 1 granted summary judgment in favor of defendants, concluding the Missouri statute does not violate the Commerce Clause and is not preempted by federal law. Southern Union appeals, challenging only the district court’s Commerce Clause ruling. Reviewing that decision de novo, we affirm.
I. Background.
Southern Union is a Delaware corporation having its principal office in Austin, Texas. Through its Missouri Gas Energy division, Southern Union provides natural gas service to over 480,000 customers in central and western Missouri. Southern Union is subject to the Commission’s regulatory authority, see Mo.Rev.Stat. §§ 393.110 to 393.295, including the requirement in § 393.190.2 that a regulated gas corporation must obtain the Commission’s prior approval before acquiring the securities of another utility, whether or not the other utility operates in Missouri.
Southern Union then commenced this action, alleging that § 393.190.2 as interpreted by the Commission violates the Commerce Clause and is preempted by the federal securities laws or by the Public Utility Holding Company Act of 1935, 15 U.S.C. §§ 79 to 79z-6. In addition, invoking the district court’s supplemental jurisdiction, Southern Union alleged that the Commission’s denial was unlawful and unreasonable under Missouri law.
See
Mo. Rev.Sat. § 386.510 (authorizing judicial review of Commission decisions). In March 2001, the district court granted summary judgment rejecting Southern Union’s federal claims.
Southern Union Co. v. Missouri Pub. Serv. Comm’n,
With this appeal pending, the state trial court ruled on remand that the Commission may issue the requested blanket approval, and that Southern Union’s application was unreasonably and unlawfully denied on the merits. However, on March 22, 2002, the court granted the Commission’s motion to vacate that judgment and dismissed Southern Union’s petition for review. Before this court, the Commission continues to assert that its pre-approval authority is constitutional. The order denying Southern Union’s application has not been overturned by the state courts. Thus, the issue before this court — whether § 393.190.2 as applied is valid under the Commerce Clause — is not moot. 2
The Commerce Clause of thé United States Constitution authorizes Congress “[t]o regulate Commerce ... among the several States.” Art. I, § 8, cl. 3. In addition, “[t]he negative or dormant implication of the Commerce Clause prohibits state taxation or regulation that discriminates against or unduly burdens interstate commerce and thereby impedes free private trade in the national marketplace.”
General Motors Corp. v. Tracy,
Southern Union argues that § 393.190.2 violates the Commerce Clause by regulating interstate stock transactions that occur entirely outside Missouri. Using terminology from some of the Supreme Court’s Commerce Clause opinions, Southern Union asserts that § 393.190.2 is per se invalid because it is both “extraterritorial” and “direct” regulation of interstate commerce. Southern Union cites no authority supporting this contention in the context of public utility regulation. If § 393.190.2 were so obviously unconstitutional, it is startling, to say the least, that the statute has gone unchallenged for nearly one hundred years.
Southern Union’s argument ignores this nation’s long history of public utility regulation. For over fifty years, Congress has regulated the interstate transmission of natural gas (the Natural Gas Act), the interstate transmission of electric power (the Federal Power Act), and the ownership of utilities (the Public Utility Holding Company Act of 1935). A major purpose of these laws was to preserve and protect state and local regulation of the distribution of natural gas and electricity to local retail customers.
See, e.g., General Motors v. Tracy,
The statute here at issue is part of Chapter 393 of the Missouri Statutes, which authorizes the Commission to establish “just and reasonable” rates for the local distribution of natural gas, electricity, water, and sewer services. Rate regulation is a complex process. A public utility’s investments in other companies can affect its regulated rate of return, if investment losses are allocated to the regulated business. Transactions between affiliated utilities can present rate regulators with difficult issues of preferential treatment and cost allocation. The abuses Congress
The Commission asserts that § 393.190.2 is part of its rate regulation responsibilities. Southern Union does not deny that assertion, and the administrative record in this proceeding supports it. For this reason, Southern Union’s contention that this is merely “extraterritorial” regulation of interstate commerce is incorrect. Though Southern Union’s stock purchases are no doubt conducted from its corporate headquarters in Texas, the Commission scrutinizes these transactions because they potentially affect the company’s regulated rate of return in Missouri. Thus, § 393.190.2 regulates interstate stock purchases because of their impact on Southern Union’s regulated local activities in Missouri. Likewise, calling this “direct” regulation of interstate commerce does not make it per se unlawful. As the Fourth Circuit observed in
Baltimore Gas & Elec. Co. v. Heintz,
In its recent Commerce Clause decisions, the Supreme Court has limited its per se rule of invalidity “to provisions that patently discriminate against interstate trade.”
Associated Indus. of Mo. v. Lohman,
Southern Union next argues that § 393.190.2 violates the Commerce Clause under the
Pike
balancing test. That test requires balancing a legitimate local public interest against its incidental burden on interstate commerce. On the issue of Missouri’s public interest, the Supreme Court has stated that “the regulation of utilities is one of the most important of the functions traditionally associated with the police power of the States.”
Arkansas Elec.
When we turn to the second part of the Pike balancing test, the burden § 393.190.2 places on interstate commerce, we are hampered by the non-specific nature of Southern Union’s application for blanket approval. Southern Union generally asserts that it takes time and money to obtain prior Commission approval, which is no doubt true. But its further assertion that “Defendants block interstate transactions by refusing to authorize Southern Union’s investments in non-Missouri Utilities” is not supported, either by the denial of a specific investment in this case, or by a review of prior decisions showing that the Commission regularly frustrates non-control investments in non-Missouri utilities. While we are not certain the district court accurately described the burden on interstate commerce as “minimal,” we cannot conclude on this record that it is substantial.
Similarly, when we come to apply the
Pike
balancing test, we are hampered by the non-specific nature of the Commission’s decision in this case. Its rationale for denying Southern Union’s blanket approval application on the merits — stock purchases may result in investment losses — might be too general to justify a ruling that severely crippled a specific interstate securities transaction with no showing that the ruling was essential to effective rate regulation.
Cf. Edgar v. MITE Corp.,
Section 393.190.2 is part of a complex regime for the regulation of public utilities in Missouri. Recognizing that local public utility rate regulation is presumptively valid, and' that the Supreme Court has rarely invoked Pike balancing to invalidate state regulation under the Commerce Clause, we conclude that Southern Union has failed to meet its substantial burden to prove that the denial of its blanket approval application resulted in an unconstitutional burden on interstate commerce.
The judgment of the district court is affirmed.

. Effective July 1, 2001, the Missouri Legislature amended the State's Business Corporations Act to provide that “no foreign corporation doing business in this state shall be required to obtain prior approval of any state agency to acquire ... the stock or bonds of another foreign corporation ... which does not conduct business in this state.” Mo.Rev.Stat. § 351.608. The plain language of this new statute seems to grant Southern Union, a foreign corporation doing business in Missouri, the right to invest in foreign utilities without seeking the Commission's prior approval. However, on remand from the district court, the state trial court ruled, in the order it later vacated, that
