    Before: GARLAND, Chief Judge, and ROGERS and MILLETT,
    Circuit Judges.
    Opinion for the Court filed by Circuit Judge Rogers.
    Concurring opinion by Circuit Judge Millett.
    ROGERS, Circuit Judge: This petition follows our remand
    for application of the “benefits exception” to the general policy
    of the Federal Energy Regulatory Commission against including
    an acquisition premium in a pipeline’s rate base. Missouri Pub.
    Serv. Comm’n v. FERC (“Missouri I”), 
    601 F.3d 581
    , 588 (D.C.
    Cir. 2010). The Commission describes its benefits exception as
    allowing an acquisition premium to be included in a pipeline’s
    rate base when the purchase price is less than the cost of
    constructing comparable facilities, the facility is converted to a
    new use, and the transacting parties are unaffiliated. See
    Missouri Interstate Gas, LLC (“Remand Order”), 142 F.E.R.C.
    ¶ 61,195, at ¶ 113 (2013). That is consistent with the
    Commission’s precedent, see Longhorn Partners Pipeline, 73
    F.E.R.C. ¶ 61,355, at 62,112 (1995), and with our own
    characterization of that precedent, see Rio Grande Pipeline Co.
    v. FERC, 
    178 F.3d 533
    , 536–37 (D.C. Cir. 1999). Although
    petitioners would distinguish past decisions on their facts, the
    court defers to the Commission’s interpretation of its own
    precedents in the challenged orders. To the extent petitioner
    raises a question whether the pipeline project benefits Missouri
    customers in the first place, the Commission permissibly relied
    on its 2002 Order certificating the Missouri Interstate Gas
    facilities for interstate use. Accordingly, we deny the petition
    for review.
    I.
    At issue is the acquisition premium associated with the
    3
    Trans-Mississippi Pipeline (“TMP”), a 5.6-mile stretch of
    pipeline that connects Missouri with Illinois beneath the
    Mississippi River. In 2002, pursuant to section 7 of the Natural
    Gas Act (“NGA”), 15 U.S.C. § 717f, the Commission issued
    Missouri Interstate Gas, LLC (which later merged to become
    MoGas Pipeline, LLC (“MoGas”)) a certificate of public
    convenience and necessity to undertake a project that included
    using the TMP for natural gas service for the first time. The
    Commission found it was in the public interest because the
    project would “provide Missouri customers the opportunity to
    diversify their gas supply options with the installation of minor
    pipeline facilities and a minimal impact to the environment,”
    Missouri Interstate Gas, LLC (“2002 Order”), 100 F.E.R.C.
    ¶ 61,312, at ¶ 2 (2002), and that in turn would improve
    reliability and supply diversity and increase competition, see 
    id. ¶¶ 15,
    17–18. On remand from this court in Missouri I, the
    Commission approved inclusion of the acquisition cost in
    MoGas’s rate base because the TMP had been devoted to a new
    use, transporting natural gas instead of oil, and the cost of new
    construction would have been greater, see Remand Order ¶¶ 95,
    110, and denied rehearing, Missouri Interstate Gas, LLC
    (“Rehearing Order”), 144 F.E.R.C. ¶ 61,220 (2013).
    Petitioner does not challenge the Commission’s factual
    findings on remand or its determination that the TMP was
    converted to a new use. Instead, petitioner challenges the
    Commission’s determination that the pipeline company had
    shown that the acquisition of pipeline facilities provided specific
    benefits in accordance with Commission precedent. Although
    acknowledging that a lower acquisition cost can produce
    benefits to customers in some cases, petitioner contends the
    Commission failed to adhere to its precedent and to examine
    whether there were actual quantifiable dollar benefits for
    Missouri customers.
    4
    A.
    NGA § 7 requires that the Commission must issue a
    certificate of public convenience and necessity before a new
    interstate pipeline may begin to operate. See 15 U.S.C.
    § 717f(c)(1)(A); Missouri 
    I, 601 F.3d at 583
    . A certificate may
    issue only if “the proposed service, sale, operation, construction,
    extension, or acquisition, to the extent authorized by the
    certificate, is or will be required by the present or future public
    convenience and necessity.” 15 U.S.C. § 717f(e). When the
    Commission issues a certificate of public convenience and
    necessity, it “sets initial rates governing the sale price of natural
    gas transported in the pipeline,” Missouri 
    I, 601 F.3d at 583
    , and
    may “attach to the . . . certificate . . . such reasonable terms and
    conditions as the public convenience and necessity may
    require,” 15 U.S.C. § 717f(e). Under that authority, the
    Commission “employs a ‘public interest’ standard to determine
    the initial rates that a pipeline may charge for newly certificated
    service.” Mo. Pub. Serv. Comm’n v. FERC, 
    337 F.3d 1066
    ,
    1068 (D.C. Cir. 2003) (citing Atl. Ref. Co. v. Pub. Serv.
    Comm’n, 
    360 U.S. 378
    , 391 (1959)). Initial rates “offer a
    temporary mechanism to protect the public interest until” the
    Commission sets permanent rates pursuant to NGA § 4, 15
    U.S.C. § 717c. Algonquin Gas Transmission Co. v. Fed. Power
    Comm’n, 
    534 F.2d 952
    , 956 (D.C. Cir. 1976).
    “Generally, when establishing the cost of service upon
    which a pipeline’s regulated rates are based, [the Commission]
    employs ‘original cost’ principles,” and “when a facility is
    acquired by one regulated entity from another, [only] the seller’s
    depreciated original cost is included in the cost-of-service
    computations, even though the price paid by the purchaser may
    exceed that amount.” Rio 
    Grande, 178 F.3d at 536
    (citing N.
    Natural Gas Co., 35 F.E.R.C. ¶ 61,114, at 61,236 (1986)). The
    cost above that amount (i.e., net-book value) is known as an
    acquisition adjustment or premium and is disallowed, unless the
    5
    “benefits exception” applies. The general policy, as described
    by the Federal Power Commission, was designed to prevent
    facilities from being sold at artificially inflated prices in order to
    increase rates, see United Gas Pipe Line Co., 25 F.P.C. 26, at 64
    (1961), and since then has been described as designed to protect
    customers from paying twice for depreciation, see, e.g., Cities
    Serv. Gas Co., 4 F.E.R.C. ¶ 61,268, at 61,596 (1978).
    The Commission has established a two-part benefits
    exception test, whereby a pipeline facility that has been
    converted from one public use to another or placed in
    jurisdictional service for the first time may include an
    acquisition premium in its rate base if the pipeline can show by
    clear and convincing evidence that its acquisition of the facilities
    will provide “substantial, quantifiable benefits to ratepayers.”
    Longhorn, 73 F.E.R.C. at 62,112. One way these benefits can
    be shown is by demonstrating that the proposed conversion
    would “result in utilization of a currently-underutilized facility,
    which could not be replicated for the price that [the pipeline
    was] willing to pay.” 
    Id. at 62,113.
    The new-use requirement
    is consistent with the Commission’s general policy of exclusion
    of acquisition premiums because customers will not be burdened
    twice for the cost of depreciating facilities. See Cities, 4
    F.E.R.C. at 61,596; see also Longhorn, 73 F.E.R.C. at 62,113;
    Natural Gas Pipeline Co. of Am., 29 F.E.R.C. ¶ 61,073, at
    61,150 (1984).
    B.
    The background to the instant petition is set forth in
    Missouri 
    I, 601 F.3d at 583
    –85. On remand from this court, an
    administrative law judge (“ALJ”) ruled, after an evidentiary
    hearing, that the TMP’s acquisition cost could not be included
    in MoGas’s rate base. Although finding the pipeline’s net-book
    value was zero and thus the entire $10,088,925 purchase price
    constituted an acquisition premium, and the pipeline was being
    6
    put to a new use, transporting natural gas rather than oil, the ALJ
    concluded that the second prong of the benefits exception test
    was not satisfied because the pipeline had “not met its burden to
    prove that the cost to construct the TMP is considerably higher
    than the pipeline’s purchase price.” Missouri Interstate Gas,
    LLC (“ALJ Remand”), 137 F.E.R.C. ¶ 63,014, at ¶ 320 (2011).
    The Commission reversed in part, finding the first prong of
    the benefits exception test had not been challenged and that the
    ALJ erred in concluding that the second prong was not satisfied,
    because “the record demonstrates that the acquisition of these
    facilities at more than their net book value results in substantial
    benefits to ratepayers.” Remand Order ¶ 2. The ALJ erred in
    requiring the difference between purchase price and construction
    cost to be “exorbitant,” ALJ Remand ¶ 313, the Commission
    explained, because nothing in Crossroads, 71 F.E.R.C. ¶ 61,076,
    on which the ALJ relied, supported such a prerequisite and
    instead only required that the benefits must be “commensurate
    with the acquisition costs that exceed the depreciated original
    costs.” Remand Order ¶ 111 (quoting Crossroads, 71 F.E.R.C.
    at 61,262) (internal quotation marks omitted). The ALJ’s
    reliance on KN Wattenberg Transmission Limited Liability Co.,
    85 F.E.R.C. ¶ 61,204 (1998), was also misplaced because that
    decision relied upon factors not present here, namely that the
    buyer and seller were affiliates and ratepayers had already paid
    for depreciation of the facility. Remand Order ¶ 112.
    To clarify, the Commission stated: “In conversion cases
    involving non-affiliates, the Commission has consistently
    allowed the full purchase price in [a] rate base when the record
    supports a finding that the purchase price is less than the cost to
    construct comparable facilities.” 
    Id. ¶ 113.
    It cited its decisions
    in Crossroads, 71 F.E.R.C. at 61,262–63; Natural, 29 F.E.R.C.
    at 61,150; and Cities, 4 F.E.R.C. at 61,596. The Commission
    elaborated on its rationale: “Allowing the full purchase price . . .
    7
    in rate base in these circumstances provides specific benefits to
    . . . ratepayers because the approved recourse rates will be no
    higher, if not somewhat lower, than if the pipeline built new
    facilities.” Remand Order ¶ 113. Further, the Commission
    noted,“[t]his ruling also provides jurisdictional companies
    appropriate incentives to purchase and utilize existing facilities
    in lieu of constructing new facilities, thereby avoiding
    unnecessary construction and the attendant environmental
    impacts.” 
    Id. Having found
    that the second prong of the
    benefits exception test was satisfied, the Commission stated it
    had no need to consider additional specific dollar benefits
    identified by MoGas once the TMP offered service, such as
    “demand charge credits to shippers, access to flexible point
    rights, and lower initial rates.” 
    Id. ¶ 114.
    On rehearing, the Commission again rejected arguments
    that its benefits exception “requires a finding of specific benefits
    in addition to a finding that the costs of acquiring the existing
    pipeline is less than cost of constructing comparable facilities”
    and that it “can only make a finding of specific benefits if the
    pipeline’s rate proposal is supported, or at least not opposed, by
    customers.” See Rehearing Order ¶¶ 48, 50. The Commission
    found no support for this requirement in Cities, Natural, or
    Crossroads, and, in light of its own precedent, did not interpret
    the description of the benefits exception in Missouri 
    I, 601 F.3d at 586
    , to require separate findings of both “‘specific dollar
    benefits resulting directly from the sale’” and a purchase price
    lower than the cost of new construction. Rehearing Order ¶ 48
    (quoting Missouri 
    I, 601 F.3d at 586
    ). Furthermore, the
    Commission noted that because the decision to issue a certificate
    of public convenience and necessity to place the TMP facilities
    into interstate service “already addressed the initial question as
    to whether there are benefits to including the cost of the TMP
    facilities in initial rates,” on remand it “appropriately applied the
    Longhorn test to determine the exact level of costs of the TMP
    8
    facilities to include in rates by evaluating whether it would cost
    more to construct new comparable facilities.” 
    Id. ¶ 49.
    Additionally, in view of its “independent obligation under [NGA
    § 7, 15 U.S.C. § 717f(e)] to ensure that initial rates are in the
    public interest,” 
    id. ¶ 50,
    the Commission explained that
    “[p]ermitting a single customer the right to veto the inclusion of
    an acquisition . . . premium in rates, regardless of the pipeline’s
    showing of specific benefits, is at odds with this statutory
    requirement.” 
    Id. So, disregarding
    the testimony of Ameren, a
    MoGas customer, challenging MoGas’s claims of additional
    specific dollar benefits was not inappropriate because the
    difference in acquisition and construction costs satisfied the
    second prong of the benefits exception test and there was no
    need to consider other possible benefits. See 
    id. ¶ 54.
    The Commission further concluded that the attempt to
    distinguish its precedents on other grounds was unpersuasive for
    the following reasons: The fact that there were existing
    customers on the merged pipeline, unlike in Crossroads, did not
    make inapposite its decision in Crossroads that specific benefits
    had been shown because the Commission had addressed
    customers’ subsidization concerns in designing MoGas’s initial
    rates. 
    Id. ¶ 51.
    Likewise, it was a misreading of Natural to
    suggest the pipeline proposed to provide service on newly
    acquired facilities for free; in that case, “the costs of the
    facilities, including the acquisition adjustment, were borne by
    the new shippers” taking service. 
    Id. ¶ 52.
    So too, United Gas
    and Kansas Pipeline were not at odds with the Commission’s
    decision on the TMP acquisition premium because the denials
    of rate base treatment for acquisition adjustments in those cases
    were based on different records. See 
    id. ¶ 53.
    In Kansas
    Pipeline Co., 81 F.E.R.C. ¶ 61,005 (1997), the State’s inclusion
    of the acquisition premiums in state-regulated rates was
    insufficient to demonstrate specific dollar benefits resulting
    from the sale. In United Gas, “there was no showing that any
    9
    rate reductions had any relationship to the payment of amounts
    in excess of the original cost.” Rehearing Order ¶ 53. By
    contrast, the Commission observed, MoGas had demonstrated
    specific dollar benefits because the purchase price of the TMP
    facilities was less than the cost of constructing comparable
    facilities. See 
    id. It further
    observed, upon acknowledging its
    statement in Enbridge Pipelines (KPC), 109 F.E.R.C. ¶ 61,042
    (2004), that proving substantial benefits under Longhorn is a
    heavy burden, that case did not involve a pipeline converted to
    a new use and that its precedents such as Cities, Natural, and
    Crossroads showed that its strong policy against inclusion of
    acquisition adjustments in rate base “‘is not inflexible.’”
    Rehearing Order ¶ 57 (quoting Cities, 4 F.E.R.C. at 61,596).
    II.
    Petitioner challenges the Remand and Rehearing Orders on
    two grounds. First, it contends that, under Commission
    precedent, “whether the purchaser has demonstrated specific
    dollar benefits resulting directly from the sale” cannot be
    satisfied simply by demonstrating that “the purchase price of the
    asset at issue is less than the cost of constructing a comparable
    facility.” Petr.’s Br. 18 (internal quotation marks omitted).
    Second, it contends the Commission was required to examine
    whether there were actual benefits to consumers beyond the
    lower purchase price and it failed to do so, in part by failing to
    address whether consumers opposed the acquisition.
    The court reviews the Commission’s decisions under the
    deferential arbitrary and capricious standard of the
    Administrative Procedure Act, and its role “is limited to assuring
    that the Commission’s decisionmaking is reasoned, principled,
    and based upon the record.” Rio 
    Grande, 178 F.3d at 541
    (internal quotation marks omitted). When ratemaking is
    involved, the court is “particularly deferential to the
    10
    Commission’s expertise.” Midwest ISO Transmission Owners
    v. FERC, 
    373 F.3d 1361
    , 1368 (D.C. Cir. 2004) (internal
    quotation marks omitted). Further, deference is due to the
    Commission’s interpretation of its own precedent. See
    Columbia Gas Transmission Corp. v. FERC, 
    477 F.3d 739
    , 743
    (D.C. Cir. 2007). The court, however, “must reverse a decision
    that departs from established precedent without a reasoned
    explanation.” Exxon Mobil Corp. v. FERC, 
    315 F.3d 306
    , 309
    (D.C. Cir. 2003) (citing ANR Pipeline Co. v. FERC, 
    71 F.3d 897
    , 901 (D.C. Cir. 1995)). We find no basis to do so here.
    A.
    Commission precedent amply supports the challenged
    orders. The precedent cited by the Commission allows inclusion
    of an acquisition premium in a pipeline’s rate base under the
    benefits exception where there has been arms-length bargaining
    so long as there is a new use and the cost of acquisition is less
    than the cost of construction. Following an evidentiary hearing
    on remand, the Commission found that applying the benefits
    exception to the TMP project ensured that “the approved
    recourse rates will be no higher, if not somewhat lower, than if
    the pipeline built new facilities.” Remand Order ¶ 113. This
    was because the acquisition cost was $1.4 million less than new
    construction. 
    Id. Counsel for
    the Commission noted that if
    there is a finding that the public convenience and necessity
    requires that a new pipeline is being put into service one way or
    another, then the question is whether it will come into existence
    through new-use acquisition or new construction, and whichever
    course of action is selected, the cost will be passed along to
    ratepayers. See Oral Arg. Rec. 40:18-40:22; 21:50-22:36 (Dec.
    12, 2014). The choice of a lesser acquisition cost benefits
    consumers, cf. Enbridge Energy Co., Inc., 110 F.E.R.C.
    ¶ 61,211, at 61,796 (2005), and the cost difference with new
    construction costs quantifies the benefits.
    11
    In Cities, 4 F.E.R.C. ¶ 61,268, the Commission had
    determined that “the public convenience and necessity requires
    Cities Service’s pipeline,” 
    id. at 61,595,
    and permitted inclusion
    of the full purchase price of a new pipeline in the rate base, 
    id. at 61,596,
    explaining that although it “generally has a strong
    policy against” including acquisition premiums in rate base,
    “that policy is not inflexible,” 
    id. “Where the
    transfer at a price
    above book value benefits consumers, it is sometimes
    appropriate to permit the entire purchase price to go into the rate
    base.” 
    Id. There, the
    depreciated book value was approximately
    $3 million, while the purchase price was $18.5 million, and
    construction of a new pipeline would have cost over $40
    million. 
    Id. The Commission
    noted that it was “also significant
    that the pipeline ha[d] not been devoted to gas utility service”
    and thus “gas consumers w[ould] not be burdened twice for the
    costs of depreciating the facilities.” 
    Id. The Commission
    ’s
    analysis was limited to those two factors: new use and a
    purchase price less than the cost of new construction.
    A differential similar to that in the instant case sufficed in
    Natural, 29 F.E.R.C. ¶ 61,073, where the acquisition cost was $1
    million lower than new construction costs. The Commission
    had found in Natural the pipeline would be in the public interest
    and thereafter allowed the acquisition premium attributable to
    the interstate portion of the new pipeline — $20 million, which
    was greater than the $6 million depreciated original cost, but
    less than the $21 million estimated cost of constructing a
    comparable pipeline — to be included in the rate base. 
    Id. at 61,150.
    The Commission noted that costs associated with the
    purchased pipeline would be borne only by customers who
    chose to use the new segment. It further explained that “gas
    customers would not be burdened twice for the cost of
    depreciating the facilities since the facilities had not previously
    been devoted to gas utility service.” 
    Id. (citing Cities,
    4
    F.E.R.C. ¶ 61,268).
    12
    In Crossroads, 71 F.E.R.C. ¶ 61,076, too, the Commission
    had found the pipeline, which was being put to a new use by
    providing natural gas in Indiana and Ohio instead of oil, was
    “required by the public convenience and necessity,” 
    id. at 61,261,
    and so allowed the $16 million acquisition cost to be
    included in the initial rate base of the pipeline. The $16 million
    acquisition cost and associated costs of $6.4 million for
    conversion and extension were “considerably less than the costs
    associated with constructing a new 201-mile, 20-inch diameter
    pipeline.” 
    Id. at 61,262.
    Hence, the Commission determined
    that “ratepayers will receive commensurate benefits from the
    acquisition of the oil pipeline.” 
    Id. Other precedent
    cited by the Commission on brief is to the
    same effect, indicating that the cost differential itself provides
    a commensurate benefit that is sufficient to satisfy the second
    prong of the benefits exception test. For example, in Longhorn,
    the Commission had concluded that the second prong of the test
    was met because “[t]he conversion will result in utilization of a
    currently-underutilized facility, which could not be replicated
    for the price that [the buyer] is willing to pay.” 73 F.E.R.C. at
    62,113. As it also noted in Cities and Natural, the Commission
    observed that “shippers who have paid for the crude oil line . . .
    are quite different from those shippers who would be charged
    for the use of the converted [natural gas] line.” 
    Id. Likewise, in
    KN Interstate Gas Transmission Co., 79 F.E.R.C. ¶ 61,268, at
    62,151 (1997), the Commission explained the second prong of
    the benefits exception test required only that “rate payers will
    realize benefits commensurate with the acquisition costs that
    exceed the depreciated original costs.” There, the “estimated
    cost of $159.2 million to complete the . . . project [wa]s
    considerably below the estimated $320 million cost to construct
    a comparable new pipeline.” 
    Id. To the
    extent petitioner attempts to distinguish the cases
    13
    cited by the Commission in the challenged orders on the grounds
    that the pipelines’ rates in Crossroads, Cities, and Natural were
    either negotiated or unopposed, or both, and so there must have
    been benefits for customers, see Petr.’s Br. 33–38, the
    Commission responded, correctly: “There is no language in the
    Commission orders in [those decisions] that suggests that
    customer support or a lack of customer opposition was an
    essential factor in the Commission’s findings in those
    proceedings,” Rehearing Order ¶ 50. The Commission pointed
    out that relying on non-opposition, as petitioner suggested,
    would have been “at odds with” its “independent obligation . . .
    to ensure that initial rates are in the public interest.” Id.; see
    also Mo. Pub. Serv. 
    Comm’n, 337 F.3d at 1076
    . Moreover,
    evidence of Missouri customer opposition was considered in the
    2002 Order, and, the Commission noted, that order was never
    challenged. Rehearing Order ¶¶ 49, 54.
    Petitioner’s reliance on United Gas, 25 F.P.C. 26, as
    requiring that a pipeline must show benefits to consumers
    beyond a construction-acquisition cost differential, is misplaced.
    In observing that acquisition costs “may or they may not be
    includible in the rate base, depending on whether it can be
    established . . . that consumer benefits flowed to the rate payers
    to the extent of the” premium, 25 F.P.C. at 50, the Federal
    Power Commission referred to rate reductions as one example
    of such benefits. Building on United Gas, Commission
    precedent has since explained why the requisite showing of
    customer benefits can be satisfied with evidence of an
    acquisition cost being lower than that of new construction. See,
    e.g., Longhorn, 73 F.E.R.C. at 62,112–13. As discussed,
    because the ratepayers for a project that has received a
    certificate of public convenience and necessity will pay rates
    based on the rate base associated either with the costs of
    acquisition or costs of new construction, acquiring a pipeline
    segment at a price cheaper than the cost of constructing a
    14
    comparable alternative can reasonably be expected to lead to
    benefits in the form of rate reductions. Other Commission
    decisions describing the benefits exception that are relied on by
    petitioner indicate no change in the Commission’s approach.
    See, e.g., Enbridge Pipelines (Southern Lights) LLC, 121
    F.E.R.C. ¶ 61,310 (2007); Enbridge Energy, 110 F.E.R.C.
    ¶ 61,211; Questar S. Trails Pipeline Co., 89 F.E.R.C. ¶ 61,050
    (1999).
    Petitioner maintains, however, that there are instances
    where the Commission has identified benefits beyond a cost
    differential (e.g., offering access to a new or under-utilized
    supply), or highlighted factual circumstances not present in the
    instant case (such as a pipeline’s reliance on a negotiated rate
    instead of a cost of service rate), or relied upon benefits that the
    Commission did not mention. See Petr.’s Br. 21, 25–31. As to
    types of benefits, the court in Missouri 
    I, 601 F.3d at 586
    , listed
    four elements it found in Commission decisions. Quoting
    Kansas Pipeline for the proposition that one factor is “whether
    ‘the purchaser has demonstrated specific dollar benefits
    resulting directly from the sale,’” Missouri 
    I, 601 F.3d at 586
    (quoting Kansas Pipeline, 81 F.E.R.C. at 61,018), the court
    characterized this as the “key” element, 
    id. at 588.
    In
    petitioner’s view, the challenged orders are inconsistent with the
    court’s statement of the test. But nothing the court said
    purported to change the test adopted by the Commission. The
    issue before the court in Missouri I was whether the
    Commission improperly included the alleged acquisition
    premium in MoGas’s initial rates while deferring resolution of
    the issue to a future NGA § 4 rate proceeding. See 
    id. at 585.
    Concluding that it had, the court noted that the Commission “did
    not directly evaluate the . . . premium according to any of the
    elements of the benefits exception test,” 
    id. at 586
    (emphasis
    added), vacated the Commission’s order with respect to the
    alleged acquisitions premium issue, and remanded that issue to
    15
    the Commission for resolution, see 
    id. at 588.
    The court thus
    had no occasion to consider the evidentiary content of the
    second prong of the Longhorn test. Previously, in Rio 
    Grande, 178 F.3d at 542
    , where the Commission had adopted a per se
    prohibition when the seller acquires an equity position in the
    purchaser that the court concluded was unsupportable, the court
    noted because it was clear Rio Grande had put the pipeline to a
    new use, see 
    id., a remand
    was called for to allow the
    Commission to address the second prong, see 
    id. at 543;
    nothing
    in Missouri I purported to question that understanding of the
    Commission’s test.
    The Commission’s analysis of its precedent in the
    challenged orders, to which we defer, refutes petitioner’s
    suggestion that the Commission has departed from the Longhorn
    test and the determination that evidence of a difference between
    acquisition and construction costs generally may suffice to
    satisfy the second prong of the test. Other Commission
    decisions relied upon by petitioner to show the Commission has
    departed from its precedent are inapposite. For instance, in
    Enbridge Pipelines (KPC), 102 F.E.R.C. ¶ 61,310, at 62,022–23
    (2003), and KN Wattenberg, 85 F.E.R.C. at 61,853–54, no new
    pipeline use was involved. See Remand Order ¶ 112.
    B.
    Petitioner also contends that a cost differential cannot
    suffice under the second prong of the benefits exception test
    absent a determination that the consumers being served will
    actually benefit. See Petr.’s Br. 38. Even assuming, as
    petitioner maintains, that the Commission was required to
    identify benefits for consumers from the TMP project other than
    a cost of acquisition lower than the hypothetical cost of
    construction, the Commission did so, appropriately relying in
    part on benefits that it had identified in 2002 when it certified
    the TMP project pursuant to NGA § 7.
    16
    Again, the clearest benefit resulting from the lower
    acquisition cost of the TMP project is the likelihood that it will
    lower costs passed along to ratepayers in using a pipeline whose
    construction the Commission determined was required by the
    public convenience and necessity. See Remand Order ¶ 113.
    In addition, the Commission noted its findings in the 2002
    Order that the TMP project would benefit customers by
    promoting reliability through providing new sources of supply
    and fostering competition. See Rehearing Order ¶ 49 & n.86.
    For instance, the Commission found that certain parts of
    Missouri had limited access to certain supply areas and the TMP
    project would increase competition and offer new sources of gas
    supply and transportation to Missouri consumers served by the
    interstate pipeline that would interconnect with the TMP. See
    
    id. (citing 2002
    Order ¶ 18). Contrary to the implication of
    petitioner’s argument, then, this is not a case in which the
    Commission certified the TMP project based principally on out-
    of-state benefits and approved an acquisition premium in the
    pipeline’s rate base to be paid by non-beneficiary in-state
    ratepayers; the court consequently has no occasion to consider
    how a petition in those circumstances would be resolved.
    Petitioner’s critique that the benefits exception test lacks
    teeth because “the estimate [of construction cost] is a
    hypothetical alternative” that “will never be put to the test,”
    Petr.’s Br. 52, is belied by the record. Petitioner challenged the
    hypothetical construction cost, prompting the ALJ to reduce it
    by $2.4 million, see ALJ Remand ¶ 314; Remand Order ¶ 110;
    Rehearing Order ¶ 55. Intervenor notes, moreover, that
    petitioner also had the opportunity to present other challenges to
    the pipeline’s evidence, such as cross-examining MoGas’s
    expert, but did not. See Intervenor MoGas Pipeline LLC Br.
    28–29.
    Finally, in its reply brief petitioner suggests that when
    17
    determining whether an acquisition premium can be included in
    a pipeline’s rate base, the Commission ought not be permitted to
    rely on the findings made when certifying the project pursuant
    to NGA § 7, lest the two questions collapse into one. See Reply
    Br. 18–19. Even assuming this argument is properly before the
    court, see Holland v. Bibeau Const. Co., 
    774 F.3d 8
    , 14 (D.C.
    Cir. 2014), nothing in this court’s remand order in Missouri I so
    limited the Commission, and the record in the instant case shows
    that the fact some benefits may be analogous does not render the
    two determinations legally indistinguishable. Of course, insofar
    as petitioner seeks to suggest there was no benefit to Missouri
    consumers from the TMP project in the first place, that
    challenge would be an impermissible collateral attack on the
    2002 Order. See Pac. Gas & Elec. Co. v. FERC, 
    533 F.3d 820
    ,
    824–25 (D.C. Cir. 2008).
    Accordingly, we deny the petition for review.
    MILLETT, Circuit Judge, concurring: In my view, the
    Commission’s decision barely ekes past our deferential
    review. The near-fatal flaw is that the Commission persists in
    a bafflegab articulation of its rule for including acquisition
    premiums in rates. On the one hand, the Commission has said
    repeatedly that the prohibition on the inclusion of acquisition
    premiums in rates is broad and emphatic, with the benefits
    exception being narrow and sparingly applied. To walk that
    narrow path, a pipeline must “show[] by clear and convincing
    evidence that the acquisition results in substantial benefits to
    ratepayers.” Longhorn Partners Pipeline, 82 FERC ¶ 61,146,
    61,542 (1998); see also, e.g., Public Service Co. of New
    Mexico, 142 FERC ¶ 61,168 P 25 (2013) (requiring “tangible
    and nonspeculative” “specific dollar benefits” that “are
    clearly related [to] and solely the result of the acquisitions”)
    (internal quotation marks omitted); Missouri Pub. Service
    Comm’n v. FERC, 
    601 F.3d 581
    , 586 (D.C. Cir. 2010)
    (“‘heavy’ burden” to show “benefits to consumers that are
    ‘tangible, non-speculative, and quantifiable in monetary
    terms’”) (quoting Kansas Pipeline Co., 81 FERC ¶ 61,005,
    61,018 (1997)).
    On the other hand, aspects of the Commission’s decision
    in this and some past cases seem to welcome automatically
    the inclusion of acquisition premiums in rates any time the
    pipeline shows that “(1) the acquired facility is being put to
    new use, and (2) the purchase price is less than the cost of
    constructing a comparable facility.” Enbridge Pipelines (S.
    Lights) LLC, 121 FERC ¶ 61,310 P 38 (2007) (quoting Rio
    Grande Pipeline Co. v. FERC, 
    178 F.3d 533
    , 536-537 (D.C.
    Cir. 1999)). Beyond any findings underlying a certificate of
    public convenience and necessity, the Commission seems to
    indicate that no showing of actual desire or demand by
    customers for the refurbished service need be made, or even
    that a new pipeline would actually have been built.
    2
    Whither that prior insistence on clear and convincing
    evidence of actual, substantial and direct benefits to
    ratepayers?
    Here the Commission says the benefit is that the rates
    “will be no higher, if not somewhat lower, than if the pipeline
    built new facilities.” Missouri Interstate Gas, LLC (“Remand
    Order”), 142 FERC ¶ 61,195 P 113 (2013). That is not the
    same as an actual, substantial benefit at all. And if that
    articulation actually captured the Commission’s position,
    what began as a clear requirement that a substantial
    affirmative benefit be shown would have transmogrified into
    a “no harm, no foul” rule, without an explanatory word being
    uttered by the Commission.
    Also seemingly overlooked by the Commission is the
    simple proposition that cheaper is not always better. In this
    case, the ratepayers got a refurbished, 50-year-old pipeline
    paired with the feeble assurance that the cost to them will be
    “no higher” than it would be for a brand new pipeline. But
    not many people would embrace as a “substantial benefit” a
    recycled, 50-year-old hand-me-down for which they were
    charged the same price as (or “no higher” than) brand new.
    What saves the Commission is that, as the court’s opinion
    notes, see Slip Op. at 10, 15-16, a careful reading of the
    agency decision shows some actual benefit to ratepayers.
    While the Commission did not repeat its analysis in detail
    here, it did expressly rely on its earlier findings in issuing a
    certificate of public convenience and necessity that the
    proposed service would provide a number of benefits
    specifically to Missouri customers. Those benefits include
    improving the reliability and diversity of natural gas supply in
    the State and increasing competition. See Missouri Interstate
    Gas, LLC (“Rehearing Order”), 144 FERC ¶ 61,220 P 49 &
    3
    n.86 (2013); Missouri Interstate Gas, LLC, 100 FERC
    ¶ 61,312 PP 14–18 (2002). Importantly, petitioner never
    sought review of those prior findings, so both petitioner and
    this court are bound by them.
    In addition, the record (just barely) documents the
    connection the Commission made between the avoided
    construction costs and anticipated lower rates for pipeline
    customers. See Wisconsin Pub. Power, Inc. v. FERC, 
    493 F.3d 239
    , 273 (D.C. Cir. 2007) (“Although FERC’s wording
    may have been less than precise on this point, the agency’s
    path may reasonably be discerned[.]”). As the Commission
    noted on rehearing, that cost differential will translate into a
    rate base that is lower than it would have been had a
    comparable pipeline been constructed, and it is that rate base
    that will serve as the foundation for the rates charged.
    Rehearing Order at P 55 n.93 (2013). 1
    To the extent there could be any question regarding the
    directness with which that reduction in the rate base would
    translate into lower prices for shippers, it would stem from
    distinct subsidization concerns that could arise if the
    Commission permitted the pipeline to charge customers a rate
    not linked directly to use of the new segment without
    measures in place to mitigate this risk. That scenario would
    distinguish this case from Natural Gas Pipeline Co. of
    America, 29 FERC ¶ 61,073 (1984), where the Commission
    1
    While the Commission’s precedent requires that the substantial
    benefit be established by “clear and convincing evidence,” this
    court’s review remains deferential. Because the Commission
    correctly identified the applicable “clear and convincing” standard,
    see Rehearing Order at P 35; Remand Order at P 44, this court
    reviews any findings of fact made pursuant to that standard only for
    substantial evidence. See Sea Island Broadcasting Corp. of South
    Carolina v. FCC, 
    627 F.2d 240
    , 244 (D.C. Cir. 1980).
    4
    specifically noted that charging rates for a newly acquired
    pipeline segment on an incremental basis ensured that the
    company, and not its customers, “b[ore] the risk of project
    failure or insufficient throughput.” See 
    id. at 61,151.
    Here, however, the Commission addressed concerns
    regarding potential subsidization specifically in its 2007
    rehearing decision approving the merger that created MoGas
    Pipeline, LLC. See Missouri Interstate Gas, LLC, 122 FERC
    ¶ 61,136 PP 67–75 (2007). No meaningful challenge to the
    rate design aspect of the Commission’s decision or its
    implications for the benefits exception has been pressed here.
    As a result, the court’s opinion decides only that
    permitting the inclusion of an acquisition premium in the rates
    on this record in a Section 7 proceeding, 15 U.S.C. § 717f,
    was a tolerable application of the Commission’s benefits
    exception. This decision says nothing about whether a future
    premium would or would not be sustainable if the
    subsidization argument were pressed and the measures the
    Commission took to address that risk were found wanting.
    Nor do we address whether future rates can be challenged on
    that ground in a Section 4 rate-setting proceeding, 15 U.S.C.
    § 717c.
    More fundamentally, nothing in our decision today
    should be held as authorizing the Commission, going forward,
    to approve the inclusion of acquisition premiums based solely
    on a determination that rates for the refurbished pipeline will
    be “no worse than” if a new, modern pipeline had been built.
    If the Commission wishes to spell the demise of the strict
    actual-benefits test of past precedent and replace it with a
    wooden “new use plus marginally cheaper than new” rule, it
    must be up front about what it is doing and grapple directly
    with the question whether the statutory and regulatory
    5
    framework and past precedent permit such a regulatory
    metamorphosis.
