[721]*721BALDWIN, J.
In this appeal from the Oregon Tax Court, appellants are three municipal corporations located in Washington State: the City of Seattle, the City of Tacoma, and Public Utility District No. 1 of Snohomish County (taxpayers). Respondent is the Oregon Department of Revenue (department). Each taxpayer owns an interest in electrical transmission capacity that was purchased from the Bonneville Power Administration (BPA) and is used for transmitting electricity over the Northwest’s federally-administered power transmission grid. Together, they appeal from a summary judgment ruling in which the Tax Court, citing Power Resources Cooperative v. Dept. of Rev., 330 Or 24, 996 P2d 969 (2000), concluded that taxpayers’ interest in electrical transmission capacity could — because much of that grid is located in Oregon — be taxed by the department as a property interest “held” by taxpayers, under ORS 307.060.
On appeal, taxpayers argue that: (1) Power Resources was wrongly decided; (2) this court’s decision in Pacificorp Power Marketing v. Dept. of Rev., 340 Or 204, 131 P3d 725 (2006) — holding that contracts between a taxpayer and a municipally-owned electric power plant demonstrated the taxpayer’s “use” of the facility for taxation under ORS 308.505 to 308.565 — does not apply in this case; and (3) the Oregon legislature’s repeal of the 2005 property tax exemption benefitting out-of-state power-generating municipalities was enacted in violation of Article IV, section 18, of the Oregon Constitution, a provision that requires that bills for raising revenue originate in the House of Representatives. For reasons we explain below, we reject taxpayers’ arguments and affirm the Tax Court’s judgment.
I. BACKGROUND
Before turning to the pertinent facts in this matter, we provide some necessary background about the relationship between taxpayers, the Pacific Northwest AC Intertie, and our earlier decisions in Power Resources and Pacificorp Power Marketing. As part of their municipal functions, taxpayers in this case generate and sell electricity to local consumers. They also buy and sell electricity on a wholesale basis, trading with other public and private entities [722]*722throughout the western United States. Taxpayers, however, do not own transmission networks of sufficient scope and capacity to transmit that electricity between their various trading partners. Consequently, to commercially transport electric power throughout the region, taxpayers rely on the Pacific Northwest/Pacific Southwest Intertie, a system of power lines and substations that stretches from the state of Washington to southern California.
The Pacific Northwest portion of the Intertie is located primarily in Oregon and is owned by three entities. BPA owns 100 percent of the Pacific Northwest DC Intertie, the part of the system that transmits power only in DC, or direct current. Another part of the system, the Pacific Northwest AC Intertie, transmits only AC, or alternating current. That part of the Intertie is jointly owned by BPA, Portland General Electric Company (PGE), and PacifiCorp. Each of the three owners maintains its own facilities and equipment that collectively make up the regional power grid for commercially transmitting AC electrical power around the Northwest and south to the Oregon/California border.
By the early 1990s, capital improvements to the Pacific Northwest AC Intertie had substantially increased the system’s transmission capacity. In response, the federal government gave select nonfederal regional entities that traded electricity on a wholesale basis an opportunity to secure rights to a permanent portion of that system’s excess transmission capacity. Eight such utilities — called Capacity Owners — entered into contracts with BPA known as Capacity Ownership Agreements (COAs).
Prior to 1996, those agreements required Capacity Owners to tender an upfront lump sum payment to BPA reflecting that user’s estimated pro-rated share of BPA’s capital and related costs. A Capacity Owner was also required to pay 21 percent of the system’s annual operating and maintenance costs. In return, a Capacity Owner received a life-of-the-facility right to use a specific portion of the system’s excess transmission capacity. According to BPA’s Record of Decision addressing the actual ownership agreements,1 the [723]*723agency’s policy goal in entering into COAs with the utilities was
“to ensure that potential New Owners had an equitable opportunity to acquire a share of transmission capacity in the Intertie that is as close to full ‘ownership’ as possible.”
In addition to a life-of-the-facility right of use, the Record of Decision regarding each COA also generally provided that Capacity Owners:
• Retained exclusive use of their respective megawatt shares of Intertie capacity;
• Possessed the option to purchase additional capacity when Intertie facilities were upgraded;
• Possessed a one-time opportunity to choose between (1) the right to use Intertie capacity for themselves and to transmit power for third parties, or (2) the right to retain transmission capacity solely for their own use. (Under the actual draft contracts, electing to abstain from third party transmissions expressly authorized BPA to transmit electricity on a capacity owner’s unused capacity in exchange for compensation. In practice however, at least two of the parties in this case — the City of Tacoma and Snohomish PUD No. 1 — amended their original COAs to allow each of them to transmit for third parties and allow BPA to use spare capacity.)
• Could, with BPA consent, sell their capacity rights; and
• Could, without BPA consent, assign their capacity rights as security for financing purposes, or otherwise engage in certain transfers to other new owners and select Pacific Northwest utilities.
In 2000, this court decided Power Resources, holding that any taxpayer possessing permanent rights to the Intertie in Oregon “held” a possessory interest in that system that should be included in the assessed value of the taxpayer’s property. Six years later, this court decided Pacificorp Power Marketing — a utility-related tax matter that did not involve the Intertie — and held that a taxpayer’s “use” of a [724]*724power facility also could serve as a basis for taxation under Oregon’s tax statutes. Combined, those two cases established alternative bases for taxing facilities in Oregon that are used to generate and/or transmit electricity. That kind of property interest ordinarily is subject to Oregon property taxes and is centrally assessed by the department. Central assessments2 can be based either on a taxpayer’s posses-sory interest in such facilities under Power Resources or on the taxpayer’s use of such facilities under Pacificorp Power Marketing. However, as explained in greater detail below, taxpayers contend that neither of those decisions applies to the circumstances here.
We now turn to the facts of this case. Like the taxpayer in Power Resources, taxpayers entered into COAs relating to the Pacific Northwest AC Intertie with BPA in 1994. The parties do not dispute the fact that, except for differences in megawatts of capacity, the material provisions of the COAs at issue here are essentially the same as the provisions of the COA at issue in Power Resources.
In 2001, following this court’s decision in Power Resources, the department levied property taxes on taxpayers based on the assessed value of the Intertie connection that each taxpayer possessed. Taxpayers challenged the department’s assessment, but their litigation ended in 2005 when the legislature enacted Oregon Laws 2005, chapter 832, section 1. Taxpayers’ controversy ceased to exist because the newly-enacted law expressly exempted foreign municipal corporations like taxpayers from taxation on Intertie-related property rights conferred by COAs.
In 2009, several Oregon legislators, seeking to broaden that exemption to include domestic electric cooperatives, introduced Senate Bill (SB) 495. SB 495 passed the Senate but, when it went through the House, the bill’s substantive provisions were removed and replaced with provisions that effectively repealed the tax exemption enacted in 2005.3 In its altered form, the House passed the bill and [725]*725returned it to the Senate, where it also passed. Signed by the Governor in July 2009, the bill was enacted into law as Oregon Laws 2009, chapter 804.
In 2010, with the statutory Intertie tax exemption no longer in place, the department renewed its efforts to tax the value of taxpayers’ Intertie transmission rights. Taxpayers responded by again filing actions in the Tax Court challenging those assessments. Among their various claims, taxpayers contended that SB 495 — the enactment that had repealed their tax exemptions — was void because it was a bill for raising revenue that had improperly originated in the Senate rather than in the House, as required by Article IV, section 18, of the Oregon Constitution.4 Taxpayers also contended that their right to access electrical transmission capacity over the Intertie did not constitute a possessory interest in Intertie capacity, facilities, or equipment sufficient to subject them to Oregon tax assessments, notwithstanding this court’s contrary decision in Power Resources.
In 2011 and 2013, the Tax Court resolved taxpayers’ claims in the department’s favor in two written opinions arising out of cross-motions for partial summary judgment. See City of Seattle v. Dept. of Rev., 20 OTR 408 (2011), and City of Seattle II v. Dept. of Rev., 21 OTR 269 (2013) (setting out the respective Tax Court judgments). In its first opinion, the Tax Court examined, among other things, taxpayers’ arguments that SB 495 violated the Oregon Constitution’s revenue origination clause. For analytical purposes, the Tax Court began by assuming that the amended version of SB 495 was, indeed, a bill for raising revenue. 20 OTR at 411. The Tax Court concluded, however, that the amendments supplying that effect were not the product of the Senate but had, in fact, originated in the House. The Tax Court explained:
“The vehicle constituting SB 495, although created in the Senate, had its entire cargo relating to raising revenue [726]*726loaded on in the House. Indeed, as the vehicle came to the House its cargo, far from being a raising of revenue, was further extension of tax exemptions. Accordingly, all of the substantive concerns that lay behind the Origination Clause are satisfied. The burden of taxation on the people originated in the House and emanated from that body.”
Id. at 412.
In its second summary judgment opinion, the Tax Court addressed, among other things, taxpayers’ contention that they did not, as a matter of law, hold, use, or otherwise have any possessory interest in the Intertie that was subject to Oregon taxation. Taxpayers’ primary argument was that Power Resources had been wrongly decided. The department’s response was that taxpayers were subject to taxation either under Power Resources or Pacificorp Power Marketing.
The Tax Court rejected taxpayers’ argument and held that “Power Resources controls as to whether the contract relationships under the COAs result in taxpayers having property taxable in this state.” 21 OTR at 273. Given that holding, the Tax Court did not find it necessary to rule on the applicability of Pacificorp Power Marketing. Id. Taxpayers then appealed to this court under the direct review provisions of ORS 305.445.
II. ANALYSIS
A. Power Resources
On appeal, taxpayers first contend that this court wrongly decided Power Resources because the underlying Tax Court decision in that case had been based on the taxpayer’s “incomplete and inaccurate and, therefore misleading” stipulation that its contract with BPA had given it the right to “use” a portion of the Intertie. According to taxpayers, that ill-advised stipulation led this court to incorrectly “assume” that the taxpayer in Power Resources possessed an “exclusive right to a definable part” of the Intertie. Taxpayers set out to rectify that claimed error by arguing that the COAs at issue here vest taxpayers only with “Scheduling Rights,” i.e., the right to add to and/or withdraw from the electricity being transmitted on the Intertie. Consequently, taxpayers assert [727]*727that their contracts with the BPA are simply transmission agreements that provide taxpayers with services no different from the untaxed transmission services available to ■ noncapacity-owning utilities under the federal government’s Open Access Transmission Tariffs (OATTs).5 According to taxpayers, under both taxed and untaxed transmission agreements, their only role in transmitting power over the Intertie is to tender a request for that service to BPA and then either (1) make electricity available to the agency for transmission from Washington State, or (2) ready the facilities needed to receive electricity transmitted to Washington State. That limited degree of use, taxpayers argue, is inconsistent with any kind of possessory interest in a system that is, they claim, “owned, used, and controlled exclusively by its owners — BPA, Portland General Electric Company, and PacifiCorp.”
A central premise underlying taxpayers’ arguments is that use of the Intertie is the sine qua non of possession for purposes of establishing taxation under ORS 307.060. Indeed, taxpayers’ position appears to be that establishing the fact of the taxpayer’s Intertie use in Power Resources was somehow central to this court’s decision in that case. A brief discussion of Power Resources, however, demonstrates why taxpayers’ position in that regard is not well taken.
In Power Resources, the taxpayer was a Portland-based cooperative that owned shares in a number of electrical generation facilities, among them, the Boardman Coal Plant near Boardman, Oregon. In 1992, the taxpayer entered into a long-term agreement to sell electricity from the Boardman plant to a California irrigation district. Among other things, that agreement required the taxpayer [728]*728to use its “best efforts” to transmit the power it sold over the Intertie.
To meet that obligation, the taxpayer entered into a COA with the BPA in 1994. Under that agreement, the taxpayer received 50 megawatts (MW) of transmission capacity for the physical life of the Intertie in exchange for a lump sum advance payment of approximately $10.75 million and the promise to pay a proportionate share of the Intertie’s operating, maintenance, and replacement expenses. The agreement expressly defined taxpayer’s resulting capacity share in terms of transfer capability on the Intertie that was “owned by [taxpayer] pursuant to this agreement.”
Under that COA, BPA retained all rights to operate, maintain, and manage the Intertie. Although taxpayer was entitled to 50 MW of Intertie capacity, it was required to schedule its electrical transmissions with BPA in advance and to abide by BPA’s scheduling procedures. An amendment to the COA subsequently clarified that the taxpayer had a right to use its capacity share to “wheel” — i.e., transmit — electricity for other entities. The agreement also permitted BPA to use any other capacity unscheduled by the taxpayer, but required the agency to compensate the taxpayer for its use.
In 1996, the department assessed the total value of the taxpayer’s properties at over $45 million, an amount that included nearly $11 million as the assessed value of the taxpayer’s Intertie share. In upholding that assessment over the taxpayer’s challenge, the Tax Court concluded that, because the taxpayer had exclusive control, subject to reasonable limitations, over a part of the Intertie, the taxpayer “held” that part of the Intertie within the meaning of ORS 307.060 (1995).6 Then, as now, ORS 307.060 (1995) sets out [729]*729an exception to ORS 307.040, the statute that generally exempts all property of the United States from taxation in Oregon. ORS 307.060 (1995) provided, in relevant part:
“Real and personal property of the United States or any department or agency thereof held by any person under a lease or other interest or estate less than a fee simple * * * shall be assessed and taxed as for the full assessed value thereof subject only to deduction for restricted use.”
On appeal to this court, the taxpayer in Power Resources argued that, as used in ORS 307.060 (1995), the phrase “held by any person” should be construed to mean some degree of actual physical possession and occupation of a property. Under that construction, the taxpayer continued, only BPA could be said to physically “hold” the Intertie, a circumstance that effectively prevented anyone else, including the taxpayer, from “holding” it in the same sense.
This court disagreed. In doing so, the court articulated two salient points:
“(1) [AJlthough a ‘possessory’ interest always is marked by some degree of control and some degree of exclusivity, neither absolute control nor absolute exclusivity is required; and (2) the test for the existence of a possessory interest necessarily varies with the nature of the property at issue.”
Power Resources, 330 Or at 31. The court recognized that, among the indicia of exclusivity and control evident in the taxpayer’s agreement with BPA, the 50 MW of electrical transmission capacity allotted to the taxpayer: (1) constituted an “exclusive right to a definable part” of the Intertie; (2) could be used — or not used — in any way that the taxpayer wished; and (3) existed as an irrevocable right for the life of the Intertie, a right that could not be diminished by adding other capacity owners to the system. Id. After noting that the transmission of electricity over the Intertie constituted its only apparent beneficial use, the court concluded:
“The property involved in this case — an electric transmission grid — cannot physically be divided usefully among [730]*730its owners. However, that limitation has not prevented taxpayer from investing in the expansion of the system, sharing the costs of its upkeep, and thereby obtaining an exclusive right to use and control the system to the extent necessary to permit transmission of 50 MW of electricity for taxpayer’s own benefit. In this context, that is sufficient; taxpayer’s 50 MW capacity ownership share in the Intertie is a possessory interest in that entity. Put differently, taxpayer ‘holds’ a share of the property that makes up the Intertie and may be assessed and taxed for that share to the extent provided in ORS 307.060.”
Id. at 32 (internal citation omitted) (emphasis added).
Given the importance of stare decisis to the judicial decision-making process, taxpayers shoulder a substantial burden in attempting to persuade us that Power Resources was incorrectly decided. As we observed in Farmers Ins. Co. v. Mowry, 350 Or 686, 698, 261 P3d 1 (2011):
“Few legal principles are so central to our tradition as the concept that courts should ‘[t]reat like cases alike,’ and stare decisis is one means of advancing that goal. For those reasons, we begin with the assumption that issues considered in our prior cases are correctly decided, and ‘the party seeking to change a precedent must assume responsibility for affirmatively persuading us that we should abandon that precedent.’”
(Internal citations omitted.) Taxpayers have not persuaded us that we should abandon Power Resources as precedent. Nor have taxpayers persuaded us that Power Resources is not controlling precedent in this case.
As our discussion in Power Resources makes clear, the features of exclusivity and control — not use — supported our conclusion that the taxpayers in that case held a pos-sessory interest in the Intertie. That the fact of usage was stipulated to by the parties in Power Resources is not helpful to taxpayers here. In this case, those same features of exclusivity and control of transmission capacity are present under facts that are virtually identical to the facts in Power Resources. In addition, the record shows that taxpayers’ agreements with BPA allows them to (1) assign their capacity rights as security for financing purposes, (2) engage in certain capacity transfers with other capacity owners and [731]*731select Pacific Northwest utilities, and (3) with BPA consent, sell their capacity rights outright. Consequently, we hold that the degree of exclusivity and control enjoyed by taxpayers here with regard to their capacity shares in the Intertie establishes the taxability of those shares under Power Resources.7
B. Article IV, Section 18
We now address taxpayers’ contention that the Oregon legislature’s repeal of the 2005 property tax exemption benefitting out-of-state municipal corporations was enacted in violation of Article IV, section 18, of the Oregon Constitution. That provision requires that “bills for raising revenue shall originate in the House of Representatives.” Or Const, Art IV, § 18.
As previously noted, taxpayers — as foreign municipal corporations — were exempted from taxation on Intertie-related property rights by the enactment of Oregon Laws 2005, chapter 832, section 1. However, in 2009, some legislators sought to broaden that exemption to include electric cooperatives and, to that end, introduced Senate Bill (SB) 495 in the Oregon Senate. SB 495 passed the Senate and then moved to the House. The House subsequently removed all of the bill’s substantive provisions and replaced them with provisions that effectively repealed the prior 2005 tax exemption. The House then passed the bill and returned it to the Senate, where it also passed. The bill was signed by the Governor and became law. Or Laws 2009, ch 804. As a result, taxpayers were placed on the same footing as in-state entities holding Intertie property rights and no longer had the benefit of the tax exemption. On appeal, taxpayers reprise their arguments made below that SB 495 was a “bill[] for raising revenue” and that the bill did not “originate in the House of Representatives” in violation of Article IV, section [732]*73218. We therefore turn to whether SB 495 was a “bill[] for raising revenue” under the origination clause.8
In Bobo v. Kulongoski, 338 Or 111, 107 P3d 18 (2005), this court adopted an analytical framework for determining whether a bill was written for raising revenue:
“Considering the wording of Article IV, section 18, its history, and the case law surrounding it, we conclude that the question whether a bill is a ‘bill for raising revenue’ entails two issues. The first is whether the bill collects or brings money into the treasury. If it does not, that is the end of the inquiry. If a bill does bring money into the treasury, the remaining question is whether the bill possesses the essential features of a bill levying a tax. See Northern Counties Trust[ v. Sears, 30 Or 388, 402, 41 P 931 (1895)] (stating test). As Northern Counties Trust makes clear, bills that assess a fee for a specific purpose are not ‘bills raising revenue’ even though they collect or bring money into the treasury.”
Bobo, 338 Or at 122.
Without question, by eliminating the 2005 tax exemption, SB 495 will “bring[] money into the treasury,” thus satisfying the first prong of the analysis that Bobo adopted. We must determine, then, “whether the bill possesses the essential features of a bill levying a tax.” Id. We therefore examine Northern Counties Trust to elucidate the second prong of the test adopted in Bobo.
In Northern Counties Trust, this court concluded that a bill exacting court fees from parties in litigation was not “a bill [ ] for raising revenue” within the meaning of Article IV, section 18. 30 Or at 403. In doing so, the court adopted the federal test for determining whether a bill raises revenue for purposes of Article I, section 7, of the United States Constitution (Origination Clause):
“[T]he history of the [origination clause] *** abundantly proves that it has been confined to bills to levy taxes in the [733]*733strict sense of the words, and has not been understood to extend to bills for other purposes, which may incidentally create revenue. Story on the Constitution, § 880.”
30 Or at 402 (emphases supplied).
The court also cited federal cases establishing a “trend” in favor of that narrow interpretation of the origination clause. In particular, the court quoted from The Nashville, 4 Biss 188 (1868), and Dundee Mortgage Trust Investment Co. v. Parrish, 24 Fed 197 (1885):
“In The Nashville the court [stated]: ‘It is certain that the practical construction of the provision by congress has been to confine its operation to bills, the direct and principal object of which has been to raise revenue, and not as including bills out of which money may incidentally go into the treasury, or revenue incidentally arise.’ Deady, J., in Investment Co. v. Parrish, [stated]: ‘A bill for raising revenue, or a “money bill,” as it was technically called at common law, is a bill levying a tax on all or some of the persons, property, or business of the country, for a public purpose; and the assessment or listing and valuation of the polls or property preliminary thereto, and all laws regulating the same, are merely measures to secure what may be deemed a just or expedient basis for the levying of a tax or raising a revenue thereon.’ This was predicated of the ‘mortgage tax’ law, which formerly prevailed in this state. * * * Considering the similarity of the state and national constitutions touching bills for raising revenue, and the high and unbroken line of authority upon the proper construction of the latter, it is certainly a very persuasive and weighty argument for applying the same construction to the former. The very cogent reasoning employed undoubtedly has application here, and impels us to the same conclusion touching our own state constitution.”
30 Or at 400-01.
The “mortgage tax” law at issue in Dundee Mortgage Trust was a statute that changed where mortgage taxes were owed, shifting them from the county where the lender lived to the county where the property securing the debt was located. Thus, taxable mortgages were placed on the tax rolls of the latter counties. As noted, that change was viewed as a measure “to secure what may be deemed a just [734]*734or expedient basis for the levying of a tax or raising revenue thereon” rather than as a direct levy of a tax. 24 F at 201. In so holding, the court drew a distinction between bills that actually levy taxes and the laws that collaterally provide for an assessment or the regulation of such levies. See also Mumford v. Sewall, 11 Or 67 (1883) (“[I]t is not sufficiently clear that a law which merely declares that certain property heretofore exempt from taxation shall thereafter be subject to taxation is strictly a law for raising revenue. We do not feel warranted, therefore, as at present advised, in declaring the law unconstitutional on this ground”).
With that case law in mind, we turn to whether SB 495 possesses the essential features of a bill levying a tax. Bobo, 338 Or at 122. Before SB 495 was enacted, taxpayers, as out-of-state municipal corporations, enjoyed a tax exemption for their property interests in the Pacific Northwest AC Intertie. Here, as in Dundee, the subject bill was a measure “to secure what may be deemed a just or expedient basis for the levying of a tax” rather than the direct levy of a tax. Dundee, 24 F at 201. The repeal of taxpayers’ exemption put taxpayers on the same taxation footing in Oregon as domestic electric cooperatives. Applying the narrow rule that this court adopted in Northern Counties Trust, we conclude that, in declaring that a property interest held by taxpayers previously exempt from taxation is now subject to taxation, the legislature did not levy a tax.
Taxpayers nevertheless argue for a different result, portraying the bill’s purpose as generating additional revenue by repealing taxpayers’ tax exemption. Taxpayers note that, in amending the Senate’s original version of SB 495, members of the House Committee on Revenue were cognizant of the need to exploit “legitimate, lawful, and reasonable opportunities to provide revenues for badly needed public services.” (Quoting comments of Gil Riddell, Association of Oregon Counties.) Taxpayers also point out that the legislature listed the bill as a revenue measure that would increase estimated property tax revenues by more than $1.2 million per biennium, and that those revenues were not earmarked for any specific purpose. See Revenue Measures Passed by the 75th Legislative Assembly 34 (LRO Aug 2009). Taxpayers contend that applying the framework set out in [735]*735Bobo leads to the conclusion that, because SB 495 ended a tax exemption, it was a bill for raising revenue.
The department counters that the purpose underlying SB 495 was to level the playing field between taxpayers — all of whom were once tax-exempt out-of-state entities — and Intertie capacity owners in Oregon — none of whom enjoyed the same tax exemption. The department contends that, although the original bill called for that goal to be met by extending exemptions to the Oregon-based entities, the goal was nevertheless achieved by removing taxpayers’ exemptions instead. The department argues that that intent is demonstrated by the fact that the original version of SB 495 introduced in the Senate extended the 2005 tax exemption beyond taxpayer’s Intertie holdings to include Oregon electric cooperatives that also had Intertie capacity agreements with BPA. In testimony before the House Revenue Committee, SB 495 was referred to as a “tax equity bill.” See Audio Recording, House Revenue Committee, SB 495, May 26,2009, at 9:27:39 (testimony of Sandy Flicker, Oregon Rural Electric Cooperative Assoc., discussing Senate version of Bill (A-Engrossed SB 495) as a “tax equity bill” to remedy inequitable treatment of electric cooperatives and stating “it’s not about the money”). During the Senate floor debate following the amendment, Senator Burdick stated that the amended bill “will put everybody on the same playing field in terms of the Intertie.” Audio Recording, Senate Floor Debate, SB 495, June 18, 2009 (statement of Senator Burdick in support of concurrence with House amendments and passage of B-Engrossed version of SB 495).
To be sure, the legislature likely had more than one purpose in enacting SB 495. However, under Bobo, our task is not to determine the primary legislative purpose for enacting SB 495. Rather, where a bill does generate revenue— as it does indeed here — our task is to determine “whether the bill possesses the essential features of a bill levying a tax.” 338 Or at 122. In this case, SB 495 removes a tax exemption — it does not directly levy a tax. See Northern Counties Trust, 30 Or at 403 (law that exacts fees from parties to legal proceedings is not one for raising revenue under Article IV, section 18, when funds deposited into general fund); see also Dundee Mortgage Trust Co., 24 F at 201 [736]*736(distinguishing between bills that levy taxes and bills that collaterally provide for assessment or regulation of levied taxes).
We note that taxpayers question the vitality of Northern Counties Trust and Dundee, citing the transition that occurred in Oregon from a levy-based property tax system to a rate-based system. According to taxpayers, in the state’s former levy-based system, the state determined its budget needs and then levied the taxes necessary to meet that specific goal. Because the resulting revenues were finite, repeal of a tax exemption did not create a greater influx of money into the treasury; instead, it redistributed tax burdens among taxpayers. The same is not true, taxpayers contend, of the rate-based system put into place following passage of Measure 50 in the late 1990s. Under that system, levies have been replaced by permanent tax rates, and revenues are no longer finite. As a result, taxpayers argue, repealed tax exemptions now increase revenues for the entire system, with the result that the burden of increased taxes falls solely on the newly-taxed entities.
We think, however, taxpayers’ argument misses the mark because it focuses exclusively on the revenue effect of SB 495. As we stated in Bobo, the revenue effect of a bill, in and of itself, does not determine if the bill is a “bill[] for raising revenue.” 338 Or at 122 (“If a bill does bring money into the treasury, the remaining question is whether the bill possesses the essential features of a bill levying a tax.”).9 As [737]*737we have explained, SB 495 repeals taxpayers’ tax exemption as out-of-state municipal corporations and places taxpayers on the same footing as domestic electric cooperatives. The bill does not directly levy a tax on taxpayers.
III. CONCLUSION
Taxpayers have not demonstrated that this court’s opinion in Power Resources was wrongly decided. Under Power Resources, taxpayers’ interest in transmission capacity purchased from BPA and used to transmit electricity over the Northwest’s federally administered power grid may be taxed by the department as a property interest “held” by taxpayers under ORS 307.060. Additionally, the Oregon legislature’s repeal of the 2005 property tax exemption previously benefitting taxpayers did not violate Article IV, section 18, of the Oregon Constitution; SB 495 was not a “bill[] for raising revenue” within the meaning of that provision.
The judgment of the Tax Court is affirmed.
