OPINION
SCHUMACHER, Judge.
Following rate proceedings, respondent Minnesota Public Utilities Commission (MPUC) issued an order that imputed to relator Minnegaseo, a Division of Arkla, Inc., a certain percentage of revenues from an affiliated, unregulated business. Minnegas-co's appeal to this court was stayed, pending the supreme court's decision in Minnegaseo v. Minnesota Pub. Utils. Comm'n, 529 N.W.2d 413 (Minn.App.1995), rev'd, 549 N.W.2d 904 (Minn.1996) (MAC). After the supreme court issued its decision in MAC, Minnegasco's appeal was reinstated. We reverse and remand to the MPUC to revise Minnegasco's rates prospectively, in accordance with the supreme court's decision in MAC.
FACTS
Minnegaseo is a public utility regulated by the MPUC. In November 1993, Minnegaseo petitioned the MPUC to increase its rates. The MPUC authorized Minnegaseo to begin charging interim rates, effective February 1994. The MPUC conducted a hearing and set new final rates.
Minnegaseo is affiliated with an unregulated appliance service business, which uses the "Minnegaseo" name. The MPUC found value in Minnegasco's name, image, and reputation (i.e., goodwill). The MPUC concluded that by contributing to this goodwill, Minne-gasco's ratepayers were essentially contributing to the unregulated business's profits. To compensate the ratepayers for this "contribution," the MPUC imputed 1% of the unregulated business's gross revenues to Minnegas-co, resulting in a reduction in rates that Minnegaseo was authorized to charge ratepayers.
Minnegasco's appeal to this court was stayed, pending the supreme court's decision in MAC. The supreme court issued its decision in MAC in June 1996, concluding that the MPUC lacked statutory authority to impute revenue to Minnegaseo for the value of goodwill contributed by ratepayers to the unregulated appliance business. In light of MAC, Minnegaseo argues that we should remand this ease to the MPUC with directions to authorize Minnegaseo to recover rates that it should have received, absent the unlawful imputation of revenues.
ISSUE
May the MPUC apply MAC retroactively by adjusting rates previously set in this case?
ANALYSIS
Minnegaseo claims that on remand, the MPUC should adjust the rates that Min-negaseo has been receiving from ratepayers since February 1994, because, according to the supreme court's decision in MAC, those rates have unlawfully imputed to Minnegaseo a percentage of the unregulated appliance business's gross revenues.
The MPUC, as a creature of statute, has only the authority given to it by the legislature. MAC, 549 N.W.2d at 907. Whether the MPUC has authority to act is a legal question, which this court may determine de novo. Id.
Certainly, the MPUC has the authority to amend an order, should it be reversed on appeal; the question is whether the amendment must occur prospectively from the date of the MPUC's order after remand, or whether the amendment may be applied retroactively from the date of the order that has been reversed.
The legislature has not explicitly addressed the MPUC's authority following an appeal and subsequent remand. Several provisions, however, provide insight into the legislature's intent. For example, all rates must be "just and reasonable." Minn.Stat. § 216B.08 (1996). This section supports Minnegasco's position that the MPUC should be able to change unjust or unreasonable rates following reversal and remand.
The legislature has also stated, however, that rates fixed by the MPUC following a rate hearing "shall thereafter be observed until changed, as provided by this chapter." Minn.Stat. § 216B.16, subd. 5 (1996). Furthermore, if an investigation by the MPUC reveals that rates are unreasonable or unlawful,
the [MPUC] shall determine and by order fix reasonable rates * ⅜ * to be imposed, observed and followed in the future in lieu of those found to be unreasonable or unlawful.
Minn.Stat. § 216B.23, subd. 1 (1996) (emphasis added). These provisions suggest that rates must be applied prospectively from the date of any MPUC order.
Upon a reversal by this court, the MPUC "shall proceed to determine the reasonableness of the rates on the merits." Minn.Stat. § 216.27 (1996). When read in conjunction with sections 216B.23 and 216B.16, subd. 5, this provision suggests that on remand, the MPUC may only change rates prospectively.
The legislature has also stated: The [MPUC] may at any time, on its own motion or upon motion of an interested party rescind, alter or amend any order fixing rates Any order rescinding, altering, amending or reopening a prior order shall have the sume effect as an original order.
Minn.Stat. § 216B.25 (1996) (emphasis added). In another, similar, provision authorizing the MPUC to grant applications for rehearing, the legislature has stated:
If in the commission's judgment, after the rehearing, it shall appear that the original decision, order or determination is in any respect unlawful or unreasonable, the commission may reverse, change, modify or suspend the original action accordingly. Any decision, order or determination made after the rehearing reversing, changing, modifying or suspending the original determination shall have the same force and effect as an original decision, order or determination.
Minn.Stat. § 216B.27, subd. 3 (1996) (emphasis added). Therefore, because the MPUC's original orders must be applied prospectively, according to Minn.Stat. § 216B.23, an amended order must also be applied prospectively.
Prior to 1983, appeals from the MPUC proceeded to the district court, which had the authority to "vaeate[] and set aside" an MPUC order, upon a determination that the rates set by the order were unreasonable and unlawful. Minn.Stat. § 216.25 (1982). Since 1983, appeals from MPUC orders come to this court pursuant to chapter 14, the administrative procedure act. Minn.Stat. § 216B.52 (1996) and Minn.Stat. § 216.25. Chapter 14 authorizes this court to remand, reverse, or modify an agency decision. Minn.Stat. § 14.69 (1996). No longer may an MPUC order be "vacated" on appeal upon a determination that rates are unreasonable.
Minnegasco cites Northwestern Bell Tel. Co. v. State, 299 Minn. 1, 216 N.W.2d 841 (1974), where the court addressed the issue whether the district court had erred by remanding telephone rate proceedings to the MPUC (at that time known as the Minnesota Public Service Commission) to "recompute revenue requirements and to determine an appropriate refund." Id. at 28, 216 N.W.2d at 858. The court found no statutory impediment to the refund order in the statutes governing telephone rates. Id. at 29, 216 N.W.2d at 858.
The Northwestern Bell decision is distinguishable upon two grounds. First, the telephone statutes -under consideration in Northwestern Bell did not indicate whether rates should be enforced or suspended pending appeal. Chapter 216B, however, specifically provides that absent a request for a stay, rates continue to be enforced pending appeal. Minn.Stat. § 216B.58 (1996). Therefore, absent a stay, the legislature apparently intended that the MPUC lacks the power to retroactively adjust rates when an appeal is concluded.
Second, the telephone statutes at issue in Northwestern Bell stated: "[I]f the court finds that the order appealed from is unjust, unreasonable, and not supported by the evidence, it shall make such order to take the place of the order appealed from as is justified by the record before it." Id. at 29, 216 N.W.2d at 858 (quoting Minn.Stat. § 287.25 (1974)) (emphasis added). Here, on the other hand, chapter 216 provides that upon a reversal by this court, the MPUC "shall proceed to determine the reasonableness of the rates on the merits." Minn.Stat. § 216.27.
We are persuaded by the supreme court's decision in Peoples Natural Gas Company v. Minnesota Pub. Utils. Comm'n, 369 N.W.2d 530 (Minn.1985). There, the court addressed a situation where the MPUC had ordered a company to refund rates collected in contravention of an MPUC order for interim rates. The court observed that retroactive ratemaking is prohibited, explaining:
Ratemaking is a quasi-legislative function and legislation operates prospectively. Indeed, the Public Utility Act expressly prohibits retroactive ratemaking. Minn. Stat. § 216B.23, subd. 1 (1984), provides: "[T]he commission shall by order fix reasonable rates to be imposed, observed and followed in the future." (Emphasis added.) See also Minn.Stat. § 216B.16, subd. 5 (1980) ("If, after the hearing, the Commission finds the rates to be unjust or unreasonable or discriminatory, the commission shall determine the level of rates to be charged or applied by the utility ⅜ and the rates are thereafter to be observed . ").
Id. at 533. - The Peoples court concluded that the MPUC had no authority to order the disputed refunds. Id. at 534. The court found significant the fact that the legislature had not expressly granted refund powers to the MPUC, noting that courts are reluctant "to expand by implication upon express legislative grants of authority to administrative agencies." Id. at 535. The court concluded:
This much is clear. Public regulation of utility rates is an intricate, ongoing process. A reallocation of rates may set in motion an ever-widening set of consequences and adjustments, and a refund not under bond may further complicate these consequences.
Id. The Peoples decision supports our conclusion that the MPUC lacks authority, in the absence of express legislative sanction, to retroactively amend an order following remand by this court.
In light of our decision, we need not address the MPUC's alternate argument that Minnegaseo's appeal has been rendered moot by intervening rate proceedings.
DECISION
The decision of the MPUC to impute revenues to Minnegasco is reversed, and this ease is remanded to the MPUC to prospectively adjust rates in accordance with the supreme court's decision in MAC.
Reversed and remanded.
. The parties' reference to the case as MAC, apparently derives from an acronym for the corn-plaining party in that case, the Minnesota Alliance for Fair Competition.
. The supreme court interpreted that authority as follows:
We think the only feasible rule is that, when an order of the commission is set aside and vacated by the court upon an appeal under § 216.25, the matter stands before the commission exactly as if no order had been made

Hvidsten Transport, Inc., 268 Minn. 176, 185, 128 N.W.2d 334, 341-42 (1964) (stating that when order is vacated and set aside on appeal, the preceding order is left "without any efficacy whatsoever"); State v. Northern Pac. Ry. Co., 229 Minn. 312, 330, 39 N.W.2d 752, 762 (1949) (stating that "[i]f the notice of appeal presents to the district court a material issue upon which the commission's findings and order are found to be unreasonable or unlawful, the entire order of the commission must be vacated and set aside").
