OPINION
I. INTRODUCTION
This case requires us to determine whether an electric utility that supplies electric service within a specific geographic area pursuant to a certificate of public convenience and necessity must obtain regulatory commission approval before selling power outside its assigned geographic area. Because AS 42.05.221(a) requires a utility to obtain an additional certificate for each type of utility service it provides and because the appellant in this case did not obtain such a certificate, we affirm the decision of the Regulatory Commission of Alaska.
II FACTS AND PROCEEDINGS
Chugach Electric Association, Inc. (Chu-gach) is an electric utility that has received a certificate of public convenience and necessity from the Regulatory Commission of Alaska 1 (commission) to supply electric service to consumers within a specific geographic area. Anchorage Municipal Light and Power (ML&P) is also a public utility authorized to provide electric service to consumers under a certificate of public convenience and necessity.
In the fall of 1997, Chugach offered to sell electricity directly to two commercial customers who were requesting it from Chugach. Because these customers were located in the service area designated for ML&P, Chugach offered to compensate ML&P for distributing the electricity as well as metering and related services 2 at a rate to be determined by the commission.
ML&P responded to Chugach's offer by filing a complaint with the commission alleging that Chugach was violating Alaska law by attempting to serve customers outside its geographic area. ML&P asked the commission to enjoin Chugach from providing elec
Both parties moved for summary judgment. The commission held that "[the Legislature's charge in AS 42.05.221(d) to the Commission to eliminate competition that the Commission finds is not in the public interest impliedly authorizes the Commission to grant monopolies when competition is not in the public interest." The commission also held that the provision of electric power constituted a service and therefore was subject to AS 42.05.22l1(a). It further held that AS 42.05.221(d) does not restrict the commission's authority to regulate competition between electric facilities to only those areas where duplication of facilities and competition already exists. Finally, the commission ruled that federal antitrust principles did not apply, but that if they did apply, ML&P would be immune under the state action doe-trine. Accordingly, the commission ruled in ML&P's favor.
. On appeal, Superior Court Judge Sen K. Tan affirmed the commission's order and final judgment. In his decision, Judge Tan ruled that AS 42.05.221(a) requires Chugach to obtain prior approval from the commission before selling electricity outside of its allotted geographical area. The superior court also concluded that the commission's interpretation of state law did not implicate any federal antitrust legal doctrines or principles, and that the state action immunity doctrine applied and was satisfied.
Chugach now appeals to this court.
III. STANDARD OF REVIEW
In an administrative appeal where the superior court acts as an intermediate appellate court, we directly review the agency action in question. 4
Chugach and the commission agree that the issues before this court are not matters "that fall within [the commission's] unique expertise" 5 as this issue presents a matter of strict statutory construction. 6 Because no agency expertise is involved, we review the commission's statutory construction under an independent judgment standard. 7 "As we substitute our judgment, it is our duty 'to adopt the rule of law that is most persuasive in light of precedent, reason, and policy " 8 '
We review the commission's findings of fact for clear error and reverse only if there is not substantial evidence to support
IV. DISCUSSION
Chugach Must First Obtain a Certificate of Public Convenience and Necessity Before Attempting To Sell Its Electricity.
Chugach maintains that the commission does not have the authority to restrain competition between electric utilities by prohibiting Chugach from selling electricity without first obtaining a second certificate of public convenience and necessity to serve power in a particular geographic location. Instead, Chugach argues, the commission may only limit competition for a commodity such as the sale of electricity once it has determined the utilities are already competing and that such competition is not in the public interest. 11 ML&P and the commission argue that the statutory language is clear that an additional certificate is needed for each new use and that only in instances where a certificate has been previously obtained does AS 42.05.221(d) apply.
Alaska Statute 42.05.221(a) provides:
A public utility may not operate and receive compensation for providing a commodity or service without first having obtained from the commission under this chapter a certificate declaring that public convenience and necessity require or will require the service. Where a public utility provides more than one type of utility service, a separate certificate of convenience and necessity is required for each type. A certificate must describe the nature and extent of authority granted in it, including, as appropriate for the services involved, a description of the authorized area and seope of operations of the public utility.
Alaska Statute 42.05.221(d) provides:
In an area where the commission determines that two or more public utilities are competing to furnish identical utility. service and that this competition is not in the public interest, the commission shall take appropriate action to eliminate the competition and any undesirable duplication of facilities. This appropriate action may include, but is not limited to, ordering the competing utilities to enter into a contract that, among other things, would:
(1) delineate the service area boundaries of each in those areas of competition;
(2) eliminate existing duplication and paralleling to the fullest reasonable extent;
(8) preclude future duplication and paralleling;
(4) provide for the exchange of customers and facilities for the purposes of providing better public service and of eliminating duplication and paralleling; and
(5) provide such other mutually equitable arrangements as would be in the public interest.
Chugach argues that by not making findings under AS 42.05.221(d), the commission placed a prior restraint on the competition for utilities authorized to provide a particular type of service. It argues that the correct interpretation of the two provisions of AS 42.05.221 is that a public injury and a finding of competition must first be made before the commission can restrict competition between electric utilities that already have certificates to provide electric service to the public. It claims that any other interpretation would render AS 42.05.221(d) meaningless.
1. Whether Chugach has the right to provide electric service within ML&P's area is not precluded by collateral estoppel.
ML&P argues that the commission has already applied AS 42.05.221(d) to eliminate competition between Chugach 'and ML&P. Therefore, it argues that consideration of this
Collateral estoppel bars the relit-igation by parties of an issue when:
(1) the party against whom the preclusion is employed was a party to or in privity with a party to the first action; (2) the issue precluded from relitigation is identical to the issue decided in the first action; (8) the issue was resolved by final judgment on the merits; and (4) the determination of the issue was essential to the final judgment. [12]
Chugach and ML&P have long been parties in litigation against each other resulting in an AS 42.05.221(d) determination establishing specific geographical areas in which each utility could provide its service. 13 In that earlier case, the commission recognized situations might arise where it would become necessary for one of the utilities to engage in work within the other's service area. Thus, the commission established certain procedures to address this concern, including a waiver by the incumbent utility or commission approval.
The commission also noted that there may be times when the utilities might need to run transmission or intertie lines through the other's service area. The commission chose not to limit these activities, provided that "service is not extended to new customers within that certified service area" unless allowed under another provision. We upheld the service areas established by the commission, although we vacated those portions of the order dealing with the transferring of facilities between the two parties. 14
After remand, Chugach, ML&P, and the commission resolved the issue regarding the transferring of the facilities But the issue at hand is distinct from the previous litigation. Here, instead of arguing that it has a territorial right to proceed, Chugach raises a matter of statutory interpretation. It questions how AS 42.05.221(a) and (d) should be applied. ML&P contends that the commission's prior order precluded Chugach from retaining or acquiring customers within ML&P's area. But this is separate from the issue of whether a determination must be made under subsection (a) or under subsection (d) before allowing Chugach to procure customers. Chugach also distinguishes this claim in that the previous order was specific to distribution only, making no determination about providing the commodity of electricity itself outside of Chugaeh's service area. Finally, all of the commission's decisions are predicated on the public interest. But the public interest might have changed since the commission's previous orders. Because the issues previously resolved and the one now before the court are not identical, Chugach is not estopped from litigating the present case.
In short, although Chugach and ML&P have a long history of court battles and many previous orders have been entered regarding their allocated areas, the instant action is distinct from these cases and therefore not precluded by previous decisions.
2. The commission may use its "general powers" as a means to limit competition.
The commission has implied pow-erg.5 An organization like the commission. 15 is an administrative agency that has whatever powers are expressly granted to it by the legislature or conferred upon it by implication as necessarily incident to the exercise of powers expressly granted." 16
Chugach reads the commission's order to say the commission's power to limit
3. The commission's and superior court's interpretation of AS 42.05.221(a) and (d) does not render subsection (d) meaningless.
In Alaska, a certificate of public convenience and necessity does not confer a grant of monopoly power.
19
Thus, Chugach claims that any previously certified utility is allowed to begin competing for consumers without additional advance notice or approval from the commission. The only check on this competition, according to Chugach, is AS 42.05.221(d), which allows competition to be
The plain language of AS 42.05.221(a) requires an additional certificate prior to any utility providing an additional type of service. 20 Chugach presents no legislative history to contest this plain meaning, nor does it present any case law to support its interpretation. 21 Chugach argues that because AS 42.05.221(d) is the only subsection to mention competition, it is therefore the only part of the statute that regulates competition. But the commission has other statutes it may utilize to limit competition. Alaska Statute 42.05.221(a) is one of these. Under AS 42.05.241, "a certificate may not be issued unless the commission finds that the applicant is fit, willing, and able to provide the utility services applied for and that the services are required for the convenience and necessity of the public." 22 The commission can grant the certificate in whole or in part and may add conditions that it deems necessary to protect and promote the public interest, including ordering the applicant to serve an area not applied for. The commission may also deny any applicant for good cause. Under AS 42.05.271, these certificates can be revoked or suspended by the commission on complaint or on its own motion after good cause is shown. A necessary consequence of these provisions regarding certificates is that a utility is usually prohibited from providing service outside of the area granted in the certificate until the utility applies for a new certificate. This is not in conflict with AS 42.05.221(d). Alaska Statute 42.05.221(a) allows the commission to prevent utilities from duplicating service until the commission finds it is in the public interest and AS 42.05.221(d) authorizes the commission to eliminate or limit any existing competition if it is found to be harmful to the public interest.
The proper application of AS 42.05.221(a) in no way conflicts with the application of AS 42.05.221(d). One situation involving the proper use of subsection (d) arose when municipally-owned utilities came within the purview of AS 42.05.221. These utilities were not previously required to obtain a certifi-caté. When the municipally-owned utilities came under this statute, both Chugach and ML&P were operating within the same district. The commission then utilized AS 42.05.221(d) to separate the two operations and provide them with distinct territories. 23
Alaska Statute 42.05.221(a) requires a separate certificate where a utility provides
Despite Chugach's claims, the commission's interpretation of AS 42.05.221(a) does not render subsection (d) of that provision meaningless. In addition, interpreting the statute as Chugach suggests would have precisely that effect.
4, Chugach incorrectly construes other statutes to show the State of Alaska's preference for competition.
Chugach argues that other relevant statutes show the State of Alaska's preference for competition over state regulation. Chu-gach relies on AS 42.05.311, which states that a public utility having any type of distribution or transmission facilities "shall, for a reasonable compensation, permit another public utility to use them when the public convenience and necessity require this use and the use will not result in substantial injury to the owner, or in substantial detriment to the service to the customers of the owners." According to Chugach, an electric utility cannot use the facilities of a second utility for any purpose other than competition, evidencing the preference for competitive over anticompetitive conduct.
Chugach fails to note the conditional language of the statute, which warrants shared use only when the "public convenience and necessity" require it. Joint use is not required by statute. Instead, if utilities fail to agree on whether joint use is appropriate, a party may apply to the commission for an order mandating it. 24 Thus, even if the legislature intended AS 42.05.3811 to engender competition, the commission may do so only after it finds that such competition is in fact appropriate.
5. There is no distinction between services and commodities under Alaska's public utilities law.
In the proceedings before the commission and the superior court, Chugach attempted to avoid the effect of AS 42.05.221(a) by arguing that the sale of electricity by itself was the sale of a commodity rather than the provision of a service. 25 Chugach argued that its certificate establishes a description of the authorized area for services only, not for commodities. Chugach thus contended that the service area description in its certificate applied only to services and not to the retail sale of the commodity of electricity itself. Both the commission and Judge Tan correctly rejected this argument based on the broad statutory definition of the word "service," which includes commodities. 26
v. CONCLUSION
The commission correctly held that AS 42.05.221(a) required Chugach to obtain an additional certificate of public convenience and necessity prior to engaging in contact with consumers regarding electricity sales outside its allotted area. This interpretation of the statute does not render AS 42.05.221(d) meaningless and is in accordance with other similar provisions. Accordingly, we' AFFIRM the decision of the superior court that affirmed the commission's decision.
