v.
CHUGACH ELECTRIC ASSOCIATION, INC., Appellee.
No. S-10080.
Supreme Court of Alaska.
November 15, 2002.
Stephen M. Ellis and Jeffrey P. Stark, Delaney, Wiles, Hayes, Gerety, Ellis & Young, Inc., Anchorage, for Appellant.
James E. Torgerson, Heller, Ehrman, White & McAuliffe, Anchorage, and Donald W. Edwards, Chugach Electric Association, Anchorage, for Appellee.
Before: FABE, Chief Justice, BRYNER, and CARPENETI, Justices.

OPINION
CARPENETI, Justice.

I. INTRODUCTION
Chugach Electric Association brought an action in the superior court seeking a declaratory judgment that the order of the Regulatory Commission of Alaska requiring Matanuska Electric Association to pay an adjusted fuel surcharge was enforceable. Matanuska counter-claimed that Chugach breached an agreement between the parties governing "rates, charges, or other tariff provisions" and sought declaratory relief. The superior court granted summary judgment in favor of Chugach. Matanuska appeals on the basis that the commission lacked jurisdiction to interpret the contract and that Matanuska's breach of contract claim is not precluded by collateral estoppel. Because we conclude that the dispute in this case centered on a contractual provision dealing with ratemaking issues falling within the commission's core jurisdiction and that Matanuska could have appealed the commission's decision, we affirm the superior court's grant of summary judgment in favor of Chugach.


*492 II. FACTS AND PROCEEDINGS

A. Facts
Matanuska Electric Association, Inc. (MEA) and Chugach Electric Association, Inc. are electrical utility corporations organized under AS 10.25. Both are subject to the regulatory authority of the Regulatory Commission of Alaska under AS 42.05.141. MEA does not produce the electricity that it sells to customers, but instead purchases the power from Chugach. The terms of these purchases are governed by a purchase and sale agreement (PSA), which was entered into on January 30, 1989 by MEA, Chugach, and the Alaska Electric Generation and Transmission Cooperative, Inc. and approved by the commission. Under the PSA, MEA is obligated to pay a pro rata portion of the actual costs incurred by Chugach in generating and transmitting the electricity.
On February 4, 1999 Chugach sent MEA a letter stating that Chugach was being assessed additional taxes and interest on gas that it purchased from the Marathon Oil Company due to a settlement between Marathon Oil and the State of Alaska (Marathon settlement). Chugach informed MEA that it would be passing $644,750, MEA's pro rata portion, on to MEA through the fuel surcharge rate adjustment process. MEA responded with a letter on February 11, 1999 stating that the recovery of these additional charges should be implemented through the procedures agreed to in the PSA, specifically in § 9(d).[1]
On February 16, 1999 Chugach filed tariff advice letter number (TA) 194-8 with the commission that, among other things, asked that Chugach be allowed to recover the liabilities incurred from the Marathon settlement in the amount of $645,000 through a twelve-month increase in the fuel surcharge rate, beginning January 1, 1999. MEA filed its objections to TA 194-8 with the commission on March 12, 1999. MEA argued that Chugach's proposal was problematic for several reasons, including that fuel surcharges were an inappropriate means of recovering these types of costs and that the proposal violated § 9(d) of the PSA. On March 26, 1999 the commission concurred with a utility tariff analyst's recommendation to approve TA 194-8 to the extent that Chugach be allowed to recover the Marathon settlement through fuel surcharges. In the recommendation, the analyst noted that "the additional Marathon taxes and royalties are uncommon, but not inappropriate, expenses pursuant to the Chugach/Marathon contract."
Chugach filed its next quarterly tariff advice letter, TA 196-8, on May 17, 1999, incorporating the additional charges to recover its Marathon-settlement liabilities that the commission had approved in its March 26 order. MEA objected to the new tariff advice letter on June 8, 1999, again claiming that Chugach's treatment of the Marathon settlement costs violated § 9(d) of the PSA. On June 25, 1999 a commission tariff analyst issued a recommendation addressing a number of issues raised by Chugach's tariff filing; regarding MEA's objection on the Marathon settlement issue, the analyst recommended that no action was necessary, since the commission had already ruled on the issue: "In the last surcharge filing, TA 194-8, MEA objected to Chugach's inclusion of Marathon *493 natural gas tax liabilities in the fuel surcharge balancing accounts. MEA again objects to the inclusion of these costs. Staff believes the Commission has adjudicated this matter and no further determination is necessary." The commission approved its staff's recommendations by order dated June 28, 1999.
On August 16, 1999 Chugach filed another quarterly tariff advice letter, TA 202-8, again incorporating the previously authorized increase in the fuel surcharge rate to recoup its Marathon-settlement liabilities. MEA objected yet again on the basis that Chugach had failed to comply with § 9(d) of the PSA. As before, the commission's staff recommended no action in response to MEA's objection, noting in a memorandum dated September 28, 1999, that the commission had already decided the issue when it approved Chugach's first quarterly tariff letter, TA 194-8, and that its decision was now final:
In TA 194-8, the Commission approved Chugach's treatment of Marathon natural gas taxes and other liabilities. Although MEA filed objections to TA 194-8, it did not request to intervene in that proceeding. Furthermore, the Commission did not suspend TA 194-8. The reconsideration period for that decision has ended.
The commission approved the staff recommendation on October 1, 1999.

B. Proceedings
On October 13, 1999 Chugach filed for declaratory and injunctive relief against MEA in the superior court. Chugach asked the superior court to rule that Chugach was entitled to a payment from MEA in the amount of MEA's quarterly pro rata share of the Marathon settlement. Chugach also asked for a declaration that MEA was bound by the commission's orders in regards to Chugach's tariff advice letters, and a declaration that the dispute is not covered by the PSA. MEA answered the complaint and counterclaimed for declaratory relief for breach of contract. Chugach then moved for summary judgment, arguing that the PSA allowed the commission to establish rates and that statutory law established that MEA was bound by the orders of the commission to pay these rates. MEA filed a cross-motion for summary judgment asking the superior court to grant its counterclaim for declaratory relief for breach of contract.
On December 13, 2000 the superior court found that the PSA specifically ceded authority over ratemaking to the commission and that statutory law gives the commission plenary authority over ratemaking. Therefore, the superior court held, the commission had jurisdiction to hear MEA's breach of contract claim. The superior court went on to hold that MEA took full advantage of its opportunity to participate in the proceedings and that the commission specifically decided the issue raised in the superior court. Also, the superior court found that MEA failed to appeal the commission's decisions by the appropriate deadlines. The superior court issued its amended final judgment in Chugach's favor on April 4, 2001.
MEA now appeals that decision.

III. STANDARD OF REVIEW
We review an appeal from summary judgment de novo.[2] "A superior court's grant of summary judgment must be affirmed if the evidence in the record fails to disclose a genuine issue of material fact and the moving party is entitled to judgment as a matter of law."[3] "All reasonable factual inferences must be drawn in favor of the party opposing summary judgment."[4] On questions of law, we will "adopt the rule of law which is most persuasive in light of precedent, reason and policy."[5]

IV. DISCUSSION

The Superior Court Did Not Err in Finding that the Commission Has Jurisdiction To Decide the Contract Dispute Between MEA and Chugach.
MEA argues that the superior court erred in granting Chugach's motion for summary *494 judgment because the commission did not have jurisdiction to interpret the PSA. MEA's argument rests on the premise that the commission is a regulatory body set up to establish utility rates, not to settle contract disputes. The dispute on appeal is whether the PSA imposes a duty on Chugach to convene a Joint Committee prior to passing fees from the Marathon settlement on to MEA. Chugach argues that the parties intended the commission to have jurisdiction over the PSA as evidenced by § 9(e) of the PSA.[6]
We hold that, in entering into a private contract, MEA and Chugach were capable of bargaining over the method of dispute resolution that would be used in settling contract disputes. As evidenced by § 9(e)(3) of the PSA, the parties agreed to have issues of interpretation of the PSA determined by the commission. In cases involving other types of contracts, we have held that parties to a contract are bound by the terms of the contract and, particularly, by dispute resolution procedures of that contract.[7]
Moreover, AS 45.05.141[8] gives the commission the power to "do all things necessary or proper to carry out the purposes and exercise the powers" it is granted in the law. As we have stated:
This provision presents two guiding principles for determining the extent of the [commission]'s jurisdiction under specific provisions of the Act. On the one hand, it includes a principle of limitation, restricting the [commission]'s power to the specific jurisdictional areas of its "stated purposes." On the other hand, it includes a principle of expansion, mandating that the [commission]'s power to act within its specific areas of jurisdiction "is to be liberally construed."[9]
Because § 9(d) of the PSA expressly deals with issues lying within the commission's core area of jurisdictionchanges in rates, charges or other tariff provisionsand because § 9(e)(3) evinces the parties' intent to submit to the commission any rate-related disputes arising under the PSA, we conclude that interpretation of § 9(d) was within the jurisdiction of the commission. Accordingly, we affirm the decision of the superior court in granting Chugach's motion for summary judgment.
Because we hold that the commission is the appropriate venue for disputes concerning § 9(d) of the PSA, we need not reach the issue whether MEA was collaterally estopped from bringing its breach of contract claim in *495 the superior court. We hold that the commission had the power to interpret the PSA and that MEA should have appealed from the commission's decision if it felt that this decision was in error.

V. CONCLUSION
Because the PSA gave the commission the power to interpret the PSA and that interpretation of the PSA is within the scope of the commission's power to set rates, we AFFIRM the decision of the superior court.
