We granted certiorari to review
Union Rural Electric Association, Inc. v. Town of Frederick,
I.
Union is an electric utility serving an area adjacent to Frederick, Colorado pursuant to a certificate of public convenience and necessity issued by the Public Utilities Commission (PUC). Frederick operates a municipally owned electric utility. After annexing two tracts of land included in Union’s certificated territory, Frederick extended utility service from its municipal facilities into the annexed area which had been served by Union. The municipal utility ran its lines to a church and a subdivision in the annexed area even though Union had already installed lines near both properties. In extending the lines into the annexed area, Frederick sought only to provide electric service requested by new customers within the areas annexed to the town. 1
Union brought suit to enjoin Frederick from providing electric service in Union’s certificated territory, claiming that the extension of service infringed upon its absolute right to serve the certificated territory. Conversely, Frederick claimed that the annexations brought the areas within the municipality’s jurisdiction, which it was then free to serve. According to Frederick, it need not observe Union’s territorial boundaries under the certificate of public convenience and necessity because Article XXV of the Colorado Constitution excludes municipally owned utilities from the jurisdiction of the PUC. The district court agreed with Frederick and denied Union’s application for injunctive relief and the Court of Appeals affirmed. We agree with the Court of Appeals. In our view, the constitutional constraints on the PUC’s jurisdiction limit the PUC’s authority to regulate municipally owned utilities operating within the municipality. Therefore, the grant of the certificate of public convenience and necessity to Union to provide electric service within the certificated area operates only to preclude other similarly certificated public utilities within the PUC’s jurisdiction from interfering with Union’s right to provide service.
II.
The Colorado Constitution specifically limits the jurisdiction of the PUC. By limiting the PUC’s jurisdiction, the Constitution correspondingly restricts the scope of the rights granted by the PUC to public utilities. There are two constitutional provisions which circumscribe specifically the jurisdiction of the PUC and are, therefore, dispositive of the issues raised in this case. First, Article V, § 35 of the Colorado Constitution provides:
“The general assembly shall not delegate to any special commission, private corporation or association, any power to make, supervise or interfere with any municipal improvement, money, property or effects, whether held in trust or otherwise, or to levy taxes or perform any municipal function whatever.”
In
Town of Holyoke v. Smith,
“On principle it would seem entirely unnecessary to give a commission authority to regulate the rates of a municipally owned utility. The only parties to be affected by the rates are the municipality and its citizens, and, since the municipal government is chosen by the people, they need no protection by an outside body. If the rates for electric light or power are not satisfactory to a majority of the citizens, they can easily effect a change, *7 either at a regular election, or by the exercise of the right of recall.”

It was against this backdrop that in 1954 Article XXY of the Colorado Constitution was added. It provides:
“In addition to the powers now vested in the General Assembly of the State of Colorado, all power to regulate the facilities, service and rates and charges therefor, including facilities and service and rates and charges therefor within home rule cities and home rule towns, of every corporation, individual, or association of individuals, wheresoever situate or operating within the State of Colorado, whether within or without a home rule city or home rule town, as a public utility, as presently or as may hereafter be defined as a public utility by the laws of the State of Colorado, is hereby vested in such agency of the State of Colorado as the General Assembly shall by law designate.
“Until such time as the General Assembly may otherwise designate, said authority shall be vested in the Public Utilities Commission of the State of Colorado; provided however, nothing herein shall affect the power of municipalities to exercise reasonable police and licensing powers, nor their power to grant franchises; and provided, further, that nothing herein shall be construed to apply to municipally owned utilities.”
(Emphasis added.) The first paragraph of Article XXV grants to the General Assembly the power to regulate public utilities within home rule cities, a power which had belonged exclusively to home rule cities where the utility was local in use and extent.

v.
Public Utilities Commission,
“The last clause merely says in effect that although the power to regulate public utilities within home rules cities is transferred to the General Assembly, there is no intention to give the General Assembly authority to regulate a municipally owned utility within the corporate limits of the municipality.”

Finally, in
City of Loveland
v.
Public Utilities Commission,
*8 III.
At no time have we wavered from the principle that the Colorado Constitution specifically circumscribes the jurisdiction of the PUC. Colo. Const, art. V, § 35, and art. XXV. These jurisdictional limitations, moreover, necessarily restrict the scope of rights that the PUC may grant to public utilities. The PUC, in short, cannot grant a publicly owned utility greater rights than are available under the Colorado Constitution.
Union contends that its certificate of public convenience and necessity carries with it an exclusive right to provide service to the certificated area to the exclusion of all other utilities, including municipally owned utilities operating within municipal limits. We agree with Union that once an area has been certified by the PUC to one public utility, the commission may not certificate another public utility to service that same area.
Public Utilities Commission v. Home Light & Power Co.,
Western Colorado Power Co., supra, and Public Utilities Commission v. Home Light and Power Co., supra, provide the basis for Union’s general contention that a certificate of public convenience and necessity vests the utility with a protectable property right to provide utility service in a certificated area to the exclusion of competing public utilities. In each of these cases, however, the competing utility was within the constitutional jurisdiction of the PUC. In this case, Frederick, the competing utility, was beyond the jurisdiction of the PUC.
Frederick was well within its rights as a municipality when it annexed the adjacent territory. Similarly, there is no doubt that Frederick had a constitutional right to construct and operate a municipally owned facility to furnish utility service to customers within its corporate limits. It is axiomatic that a municipality may furnish utility service to new customers within its municipal boundaries even where there is a public utility already operating within the corporate boundaries.
Public Utilities Commission v. City of Loveland,
“We are not, however, willing to assent to the proposition that, because private capital has invested in a public utility, a municipality may not lawfully and justly provide a like utility for the benefit of its citizens. To hold the contrary would be to assert that no competition in the furnishing of light, power, gas, water, and kindred matters should be allowed, once a plant has been provided to supply any of them.”

Accordingly, the judgment of the court of appeals is affirmed.
Notes
. Because Frederick is not taking existing customers from Union, we do not decide whether such action would constitute a taking of a property right requiring compensation.
. The pertinent language of the provision states: “[T]hat nothing herein shall be construed to apply to municipally owned utilities.
. The only recognized exception to this rule is that the PUC may grant a certificate to a competing public utility when the original certificated utility is either unwilling or unable to service an existing or newly-developing area.
