    Sitting by designation under Del. Const. art. IV, § 12.
    When Exelon Generation Acquisitions purchased Deere & Company’s wind
    energy business, it agreed to make earn-out payments to Deere if it reached certain
    milestones in the development of three wind farm projects that were underway at the
    time of the sale. One of the projects was the Blissfield Wind Project, which was
    defined in the parties’ Purchase Agreement as “the wind project under development
    in Lenawee County, Michigan, by Blissfield Wind Energy, LLC with a nameplate
    capacity of` 81 megawatts.”1 Included in the sale of the Blissfield Wind Project was
    a “Power Purchase Agreement”_a binding commitment Deere had secured from a
    local utility to purchase energy from the wind farm once it commenced operations.
    lt is undisputed that Exelon was unable to bring the Lenawee County site to
    fruition because of civic opposition. But shortly thereafter, Exelon managed to
    acquire another nascent wind farm from a different developer, this time at a site in
    Gratiot County, Michigan, about a hundred miles away from the site of the Blissfield
    Wind Project. Exelon managed to persuade the local utility to transfer the Power
    Purchase Agreement there, and this time, the wind farm was successful
    Deere caught wind of Exelon’s success with the new site (and its use of` the
    Power Purchase Agreement) and filed suit to recover the earn-out payment, claiming
    that “Exelon had simply relocated the Blissfield Wind Project to Gratiot County”2

    and that the earn-out payment obligation had traveled with it. Exelon denied that it
    had relocated the project, contending that, after it was prevented from developing
    the Blissfield Wind Proj ect by forces beyond its control, it acquired and developed,
    at great expense, a new project in Gratiot County with different counterparties,
    developers, equipment manufacturers, landowners, townships, counties, and
    permits.
    On cross-motions for summary judgment, the Superior Court sided with
    Deere’s interpretation of the Purchase Agreement and ordered Exelon to pay the $ 14
    million earn-out payment for successfully developing a wind farm in Gratiot County.
    We disagree with the Superior Court’s interpretation of the Purchase Agreement and
    therefore reverse.
    l
    A
    In August of 2010, Exelon agreed to acquire all of the limited liability
    company interests of John Deere Renewables, LLC, a wholly owned subsidiary of
    Deere & Company that held its wind assets. The base purchase price was $860
    million.
    One of the subsidiary LLCs that Exelon acquired was Blissfield Wind Energy,
    LLC, of which Deere owned a 50% interest, the other 50% being held by a separate
    entity called Great Lakes Wind, LLC. At the time of the transaction, Blissfield was
    2
    developing a wind farm called the Blissfield Wind Project, which the Purchase
    Agreement between Exelon and Deere defined as “the wind project under
    development in Lenawee County, Michigan, by Blissfield Energy, LLC, with
    nameplate capacity of 81 megawatts.”
    Just two months before the sale, Deere had succeeded in securing a power
    purchase agreement (PPA) for the Blissfield Wind Project with Consumers Energy
    Company, an electric utility in Michigan, Under the PPA, which stipulated that the
    Blissfield Wind Project would be located in Lenawee County, Michigan, Consumers
    agreed to purchase energy generated by the Proj ect for twenty years at a fixed rate
    schedule. lt is undisputed that a PPA is a valuable asset that helps to ensure the
    viability of a wind farm.
    At the time of the sale, Blissfield was one of three wind farms under
    development in Michigan for which Deere had secured PPAS, which the Purchase
    Agreement collectively referred to as the Michigan Wind Projects. As a condition of
    the sale, Exelon agreed that if those three Projects were to achieve certain
    development milestones, it Would pay Deere an additional amount, above the base
    purchase price, for each Project that achieved the milestones (a so-called earn-out
    payment). Whether Exelon owes Deere an earn-out payment for the Blissfield Wind
    Proj ect is at the center of this dispute.
    B
    When the Purchase Agreement was executed, the parties were aware that there
    was civic opposition to the development of a wind farm in Lenawee County. And
    although Deere represented in the Agreement that it “reasonably believe[d] that all
    material Permits necessary for the development, construction, ownership,
    maintenance, use and/or operation of the [three] Michigan Wind Projects. . . [could]
    be obtained in the ordinary course,”3 one of Deere’s disclosure schedules that Was
    attached to the Agreement warned of the possibility of a moratorium on wind energy
    projects in Riga Township, the planned location in Lenawee County for the
    Blissfield Wind Project.4 In fact, an internal Deere memorandum revealed that
    Deere believed that the vice chair of the Riga Township Planning Commission
    3 App. A336.
    4 Under headings that read “Michigan Wind Projects Permits - Blissfield Wind Proj ect,” the
    disclosure states:
    The Riga Township Planning Commission voted on August 2, 2010 to recommend
    to the Riga Township Board a 12-month moratorium on Wind energy projects,
    which is scheduled to be considered by the Riga Township Board at its September
    13, 2010 meeting The moratorium, as currently proposed, would automatically
    expire upon approval of a wind energy Zoning ordinance.
    If 15% of the registered voters in a Michigan township sign a petition requesting a
    referendum within 30 days after a Zoning ordinance is enacted in such township,
    the zoning ordinance would become subject to a referendum vote at the next
    scheduled election. Based on the level of resistance to the Blissfield Wind Project
    in Ri ga township there is a possibility that a zoning ordinance permitting the project
    would be put to a referendum
    App. A454.
    “[was] actively working with the opponents of the [Blissfield] project to prevent the
    wind projects in Riga from becoming a reality.”5 Against this backdrop, Exelon and
    Deere executed the Purchase Agreement.
    Only eleven months after they signed the Purchase Agreement, Riga
    Township passed a zoning ordinance that rendered development of the Blissfield
    Wind Project “impossible” from a regulatory perspective6 Consequently, Exelon
    provided Consumers Energy with a notice of a force majeure event under the PPA,7
    which suspended Exelon’s obligations and jeopardized its chance to use the PPA.
    C
    After the setback in Lenawee County, Exelon began to devise ways to salvage
    the PPA. Within a month of declaring the force majeure event, Exelon informed
    Consumers that it was “pursuing several alternatives,”8 including the possibility of
    submitting a request to the Riga Township authorities for a new zoning ordinance to
    allow the development to go forward, acquiring additional parcels in nearby Ogden
    App. A287.
    App. A719.
    The PPA defines “Force Maj eure” as “acts or actions beyond the reasonable control of the
    affected Party, including Without limitation, acts of God; flood; earthquake; storm or other natural
    calamity; war; insurrection; riot; curtailment (including any curtailment ordered by any Reliability
    Authority), order, regulation or restriction imposed by governmental authority; fire or explosion
    not caused by criminal acts by the Party claiming Force Majeure; transportation accidents 0r perils
    at sea; or other Similar cause beyond the reasonable control but not due to negligence of the Party
    affected.” App. A259.

    Township and constructing a wind farm there, which would have satisfied the PPA’s
    requirement that a wind farm be built in Lenawee County, and assessing the
    feasibility of “moving the Projec ” to an “alternative site . . . in a nearby county
    within Michigan.”9 Exelon ultimately decided to pursue the last of these
    alternatives, hopeful that Consumers would be willing to amend the PPA to allow
    the wind farm to be built in either Gratiot or Ionia County, rather than Lenawee. To
    that end, Exelon sent a draft letter to Consumers stating that, while it could not
    proceed with the “Blissfield Wind project . . . at the current Plant Site”10 (i.e.,
    Lenawee County), Exelon believed that the PPA could be amended with Consumers’
    consent to allow the wind farm to be built in an area in Michigan with a more
    favorable political climate for wind development
    Consumers was initially reluctant to amend the PPA,ll but eventually agreed,
    subject to the necessary regulatory approvals. This modification did not come
    without a cost to Exelon: it agreed to reimburse Consumers for tax credits
    Consumers might lose if the project were not completed before the credits expired.
    This amounted to approximately $16 million in new risk for Exelon, although, as
    
    9 App. 13178
    .
    10 App. Bl74.
    11 App. A528-29 (containing an email thread among Exelon employees in which one
    employee, who spoke with Consumers, reported to the others that while Consumers was “open to
    discussion,” it Was “not willing,” at that time, “to say that they support it” in light of Consumers’
    concerns that a transfer of the PPA to a “replacement project” would lead to delays and likely
    require regulatory approval).
    6
    will be seen, that risk never came to fruition. In due course, the amended PPA
    received regulatory approval.
    Around that same time, Exelon purchased a wind farm development known
    as the Beebe Wind Farm from another developer, Nordex USA, lnc., for $10.3
    million. This development was located in less wind-hostile Gratiot County, about a
    hundred miles from Lenawee County, and this time, there was no civic opposition
    that prevented Exelon from bringing the wind farm online. With the amendment that
    Exelon and Consumers had made to the PPA, the Beebe Wind Farm satisfied the
    PPA’s milestones, and Exelon succeeded in getting to use a PPA that seemed all but
    lost when development faltered in Lenawee County.
    Exelon did continue its efforts to develop a wind farm in other parts of
    Lenawee County, but because the other townships were as opposed as Riga to having
    a wind farm in their backyards, those efforts were unsuccessful So in May 2012,
    citing the restrictive wind energy ordinances passed by officials in Lenawee County,
    Exelon notified Deere that it was abandoning the Blissfield Wind Project. Section
    2.6(b) of the Purchase Agreement contained a mechanism for Exelon to release itself
    from its contractual obligation to continue to develop the Project if further
    development were to become commercially infeasible, and Exelon invoked that
    mechanism here:
    In the event [Exelon] reasonably determines that continuing to proceed
    with any one or more of the Michigan Wind Projects would not be
    7
    commercially reasonable and therefore determines to permanently
    cease development of and abandon such Michigan Wind Project(s),
    [Exelon] shall so inform [Deere], including the reason therefor and
    thereafter [Exelon] shall have no further obligation to [Deere] in
    connection with such development . . . .12
    II
    Deere has never contested Exelon’s assertion that it was not commercially
    reasonable to proceed with the development of the Blissfield Wind Project in
    Lenawee County. Instead, Deere contends that, despite the notice of abandonment,
    Exelon did not actually abandon the Project_it merely relocated it to the Beebe
    Wind Farm in Gratiot County and satisfied the earn-out-triggering milestones there.
    Although Deere admits that the Purchase Agreement describes the Blissfield Wind
    Project as the “wind project under development in Lenawee County” and that the
    parties, “at the time of negotiating and executing the agreement[,] intended the
    Blissfield Wind Project to be developed in Lenawee County and did not anticipate
    . . . that it would be moved,” Deere contends that there is “nothing in the Purchase
    Agreement that prevented the Blissfield Wind Project from being moved outside of
    Lenawee County.”13
    In Exelon’s View, the Blissfield Wind Project Was not moveable_it was a
    wind farm development in Lenawee County that Exelon reasonably abandoned in
    12 App. A319.
    13 Compl. 11 45.
    favor of another development In other words, the Blissfield Wind Project was, as
    the Purchase Agreement says, “the wind project under development in Lenawee
    County, Michigan,” and whether the Beebe Wind Farm achieved the Purchase
    Agreement’s development milestones is of no consequence because it is not that
    same wind proj ect.

    interpret the intent of the parties, to vary the terms of the contract, or to create an
    ambiguity.”19
    B
    We begin with the Purchase Agreement’s plain language Exelon’s obligation
    to pay Deere an earn-out for the Blissfield Wind Project was contingent upon “the
    Blissfield Wind Project achiev[ing] Completion of Development and
    Commencement of Construction.” The “Blissfield Wind Project” is defined by the
    Agreement to mean “the wind project under development in Lenawee County,
    Michigan, by Blissfield Wind Energy, LLC, with a nameplate capacity of 81
    megawatts.” Together, then, payment of the earn-out was contingent upon “the wind
    project under development in Lenawee County, Michigan,” achieving “Completion
    of Development and Commencement of Construction.”
    On its face that presents a problem for Deere, because there is no dispute that
    the wind project in Lenawee County neither completed development nor
    commenced construction-civic opposition saw to that, But Deere believes the key
    lies in the definition of the term “Completion of Development and Commencement
    of Construction.” Under the Agreement, a “Completion of Development and
    Commencement of Construction” could be triggered in one of two ways. The first is
    19 Eagle Ina'ustries, 
    702 A.2d at 1232
    .
    10
    the achievement of five development milestones that are spelled out in the
    Agreement.20 The second is the reaching of a “Commercial Operation Date.” lt is
    this second trigger that forms the basis of Deere’s argument
    “Commercial Operation Date” is yet another defined terrn-the Agreement
    explains that this term “has, with respect to any Michigan Wind Project, the meaning
    set forth in the Michigan PPA related to such Michigan Wind Project.” Exelon
    purchased three “Michigan Wind Proj ects” from Deere, the Blissfield Wind Project
    being one of them, so to find the meaning of “Commercial Operation Date” as it
    applies to the Blissfield Wind Project, the Agreement directs us to the “meaning set
    forth in the Michigan PPA related to” the Blissfield Wind Proj ect. “Michigan PPA,”
    too, is a defined term, and it refers to three different contracts, one of which is “that
    certain Renewable Energy Purchase Agreement, dated as of June 21, 2010 (as
    amended, restated, modified, superseded or supplemented from time to time),
    between Consumers Energy Company and Blissfield Wind Energy, LLC.” That is
    the PPA that, at least as of the date of the sale, related to the wind project under
    development in Lenawee County. And sure enough, the PPA contains the term
    20 Those five milestones are (l) securing relevant permits, (2) securing turbine supply
    agreements, (3) securing interconnection agreements, (4) having a Power Purchase Agreement in
    place, and (5) commencement of on-site construction of roads and foundations and completion of
    initial wind turbine construction
    ll
    “Commercial Operation Date,” and it refers to the date on which a number of
    development milestones listed in the PPA are met.
    Exelon, as mentioned, was able to persuade Consumers Energy to transfer
    the PPA to the Beebe Wind Farm once the Lenawee County site proved politically
    infeasible. To do so required an amendment to the PPA because the PPA made
    Various references to the term “Plant Site,” which the PPA had defined as “[t]he site
    upon which the Plant will be located in Lenawee County, Michigan.”21 So the two
    sides amended that definition to strike “Lenawee County” and replace it with “Ionia
    or Gratiot County”_the latter of which being where the Beebe Wind Farm was
    under development And there is no dispute that Exelon ultimately succeeded in
    achieving a “Commercial Operation Date” at the Beebe Site, as that term is defined
    in the PPA, by reaching the milestones listed in the PPA.
    The crux of Deere’s argument_which the Superior Court accepted_is that
    the achievement of a Commercial Operation Date under the amended PPA
    automatically triggered the earn-out payment under the Purchase Agreement. To be
    sure, this argument has some superficial appeal. The Purchase Agreement states that
    the earn-out is triggered upon the “Completion of Development and Commencement
    of Construction,” and one way that could occur is by the achievement of a
    Commercial Operation Date, as it is defined under the PPA. So, the argument goes,
    21 App. A239.
    12
    the achievement of a Commercial Operation Date under the amended version of the
    PPA must have triggered the earn-out under the Purchase Agreement.
    But Deere’s argument glosses over textual difficulties that arise when the
    interlocking terms in the earn-out provision are read together. As explained, the eam-
    out payment was contingent upon “the Blissfield Wind Proj ect achiev[ing]
    Completion of Development and Commencement of Construction.” Fully unpacked,
    that means that payment was contingent upon “the wind project under development
    in Lenawee County, Michigan achiev[ing]” either the five milestones specified in
    the Purchase Agreement or the milestones “set forth in the Michigan PPA related to
    . [‘the wind project under development in Lenawee, County, Michigan’].”
    Although it is true that the milestones set forth in the PPA were achieved, at the time
    they Were achieved the PPA was no longer “related to . . . [‘the wind project under
    development in Lenawee County, Michigan’]”_it had been amended to relate to the
    Beebe Wind Farm. And even if the PPA, post-amendment, still “related to” the
    Lenawee County project by virtue of the fact that it was the same agreement that, at
    one time, had related to that development, the earn-out was due only if “the wind
    project under development in Lenawee County, Michigan, achiev[ed]” the
    milestones in the PPA. But it was not that wind project that achieved the
    milestones_it was the Beebe Wind Farm, in Gratiot County.
    13
    IV
    Deere’s answer to this interpretive problem is that the Purchase Agreement’s
    description of the Blissfield Wind Project as the “wind project under development
    in Lenawee County, Michigan,” was not intended to give the term “wind project” a
    geographic component-it was just an easy way to distinguish that project at the
    time of the sale from the numerous other wind projects that Exelon purchased from
    Deere. So to Deere, it is not incongruous to say that when the Beebe Wind Farm, in
    Gratiot County, achieved a Commercial Operation Date, that meant, in the language
    of the Purchase Agreement, that “the wind project under development in Lenawee
    County, Michigan,” achieved Completion of Development and Commencement of
    Construction.” The Beebe Wind F arm was still the same “wind project”_it had just
    been moved from Lenawee County to the Beebe site in Gratiot County.
    But even granting Deere the argument that the phrase “under development in
    Lenawee County” was intended only to identify the “wind project”_not define it_
    the question still remains whether the Beebe Wind Farm could, in the meaning of
    the Purchase Agreement, be the same “wind proj ect” that was once under
    development in Lenawee County, and for which Exelon agreed to assume an eam-
    out obligation.
    14
    A
    There is no dispute that the PPA is the only common thread between the wind
    farm that was under development in Lenawee County and the Beebe Wind F arm that
    Exelon acquired from Nordex.22 Deere’s argument, then, would collapse the “wind
    proj ect” into nothing more than an idea for a wind farm and a single intangible asset,
    untethered in any way to the development that had already begun in Lenawee
    County. But a number of provisions in the Purchase Agreement belie the notion that
    the parties intended for the “wind project” to have so fluid a meaning that Exelon’s
    earn-out obligation could be triggered by its re-use of a single intangible asset from
    the Lenawee County development at a wholly separate wind farm_even an
    intangible asset as valuable as a PPA.
    Most telling are the representations that Deere made to Exelon about the status
    of the development at the time of the sale. Deere represented that Blissfield Wind
    Energy, the Deere subsidiary that was developing the project, was “targeting the
    acquisition of real property interests” that, “together with the real property interests
    already held” by the company, “would . . . constitute all of the real property interests
    necessary to develop, construct, own, operate, maintain and use the Blissfield Wind
    22 Deere points out that there is one other connection: Exelon acquired the Beebe Wind Farm
    from Nordex through the same legal entity_Blissfield Wind Energy, LLC_that Exelon
    purchased an interest in from Deere and that had been developing the wind farm in Lenawee
    County. But whatever the “wind proj ect” is, Blissfield Wind Energy is not part of it_it owns it.
    15
    Project.”23 A map in one of the schedules to the Purchase Agreement shows the
    locations of plots of land in Lenawee County that were already under lease at the
    time of the sale, as Well as the proposed locations for approximately forty-five wind
    turbines.24 The map reveals that Blissfield had already leased land for more than half
    of the turbines and was targeting the land needed for another third of them.
    Deere also represented that it was “continuing to obtain the Permits necessary
    to develop, construct, own, maintain, use and operate” the Blissfield Wind Project
    and that it “reasonably believe [d] that all material Perrnits . . . [could] be obtained in
    the ordinary course’725 (with the cautionary note that “resistance to the Blissfield
    Wind Project in [the] township” could “possibly” lead to a restrictive ordinance26).
    So whatever the precise contours of this “wind proj ec ” that Exelon acquired,
    we can safely say that it was more than just an idea for a wind farm and a PPA
    looking for a home. The project already had a real-property footprint in Lenawee
    County, and Exelon had in hand the twin representations from Deere that “no
    material impediment exist[ed] to obtaining the [remaining] real property interests”
    and that there was a path (so it seemed at the time) toward obtaining the permits for
    the wind farm to operate in Lenawee County.27

    21 App. A336.
    16
    B
    The representations that Deere made about the suitability of the Lenawee
    County site do more than just demonstrate that the “wind project” had a geographic
    anchor at the time of the sale_these representations were essential to Exelon’s
    willingness to assume the earn-out obligation
    At the time of the sale, Deere’S wind energy business included over a dozen
    wind projects that were under development, but Exelon agreed to make earn-out
    payments for only three of them: the three Michigan Wind Proj ects. And those three
    projects are the only projects for which Deere made representations that the real
    property and permits necessary for development to succeed at the sites Deere had
    chosen for each Proj ect were either already secured or attainable.
    That was no coincidence When a buyer like Exelon agrees in advance to make
    an earn-out payment for a fixed dollar amount, the buyer needs to assure itself that
    the amount it Will have to expend to achieve the earn-out-triggering conditions will
    not rise to the point that the earn-out payment will end up out of proportion with the
    project’s value. For a project like a wind-farm development, two obvious areas
    where costs could spiral are the acquisition of the land necessary to complete the
    development and the securing of the necessary approvals from government
    authorities Unexpected impediments on either of those f`ronts-like holdout
    landowners or stubborn municipalities-could quickly escalate the cost of bringing
    17
    the wind farm to fruition, eroding the project’s profitability and distorting the
    relationship between the value of the project and the fixed earn-out payment
    So it is unsurprising that in exchange for the Exelon’s willingness to agree in
    advance to a $14 million earn-out payment for the successful development of the
    Blissfield Wind Project_before knowing how much it would cost to get there-
    Exelon would insist on some assurances about the suitability of the site Deere had
    chosen. And Deere obliged by representing that, to its knowledge, there was “no
    material impediment . . . to obtaining the [remaining] real property interests” at the
    Lenawee County site and that “all material Permits necessary for the developmen ”
    of the project at that site could “be obtained in the ordinary course.”28 Those
    representations gave Exelon some comfort that Deere Was not trying to offload a
    wind development at serious risk for cost overruns in exchange for a fixed payout
    that was out of line with the development’s value.
    But to accept Deere’s interpretation, we would have to believe that after
    securing those representations about the Lenawee County site, Exelon was
    nonetheless willing to commit itself to paying the earn-out if it were able to bring a
    wind farm to operation anywhere, as long as it made use of the PPA. And that would
    upend the Purchase Agreement’s balance between the fixed earn-out payment that
    Deere demanded, and Deere’s assurances that it knew of no material obstacles in the
    22 App. A336.

    way of land or permit acquisitions at the Lenawee County site that could swell
    development costs and swing the proj ect’s value out of line with the amount of the
    earn-out.
    C
    Together, these provisions in the Purchase Agreement make implausible the
    notion that a different wind farm, situated in a different location and regulatory
    environment (and acquired from another company, no less), was the same “wind
    project” that had been under development in Lenawee County, simply because
    Exelon was able to persuade Consumers Energy to transfer the PPA there. And aside
    from the PPA being the only link between the two developments, that link was
    attenuated by Consumers’ demand that, in exchange for transferring the PPA to the
    Beebe Wind Farm, Exelon assume the risk that Consumers could lose its tax credits
    if the development were not completed in time.
    When Exelon first approached Consumers with the idea of amending the PPA
    to move it to a new development, Consumers resisted, telling Exelon that if it was
    unable to complete development in Lenawee County, then Consumers preferred “to
    go out for a rebid.”29 Although Consumers did not foreclose the idea of transferring
    the PPA to a new project, it emphasized that its highest priority was that “the
    29 App. A528.
    19
    replacement project . . . be built in 2012.”30 Missing the 2012 completion date would
    put an estimated $16 million in tax credits that Consumers was set to receive at
    risk_a risk that Consumers had to bear under the terms of the PPA as Consumers
    and Deere had negotiated them. To secure Consumers’ consent to move the PPA to
    the Beebe Wind Farm, Exelon agreed to take on this risk.31
    So while Exelon succeeded in finding a way to save the PPA after community
    opposition doomed the Lenawee County development, the PPA ended up being on
    different terms than Deere had negotiated before the sale, and that further reduces
    the little the two developments have in common.
    D
    The Superior Court offered two reasons why the “wind project” that Exelon
    purchased from Deere could be_and was_moved to the Beebe Wind Farrn.
    The first turned on the amendment the parties made to the PPA to strike the
    reference to “Lenawee County” and replace it with “Ionia or Gratiot County.” In the
    Superior Court’s view, that “amendment . . . reflect[ed] the ability of Exelon to
    change the project location.”32
    30 App. A529.
    31 As the Beebe Wind Proj ect was in fact completed in 2012, the risk did not materialize, but
    that does not mean that Exelon’s assumption of this risk did not work a material change to the
    terms of the PPA as they stood when Exelon acquired Deere’s rights to it.

    20
    But that reasoning_that Exelon’s success in amending the PPA showed that
    Exelon could move the wind project-~begs the very question that must be answered:
    is amending the PPA tantamount to moving the project? All that the amendment of
    the PPA established was that the PPA could be used for a different development It
    does not automatically follow that using the PPA for a different development meant
    that Exelon had also moved the “wind project,” as that term is used in the Purchase
    Agreement, or, more to the point, that the wind project consisted of just an idea for
    a Wind farm and the PPA, which both could be freely moved to another site with a
    simple amendment to the PPA.
    The Superior Court was of the view that the Purchase Agreement’s concept
    of the “wind project” had to travel with the PPA because the Purchase Agreement
    incorporates the milestones from the PPA as one of the two triggers for the eam-out
    payment So if the “wind project” in the Purchase Agreement were not harmonized
    with the project in the PPA, the “Purchase Agreement [could not] be given its full
    meaning.”33 But that is not so.
    33 See 
    id.
     In the course of its discussion, the Superior Court opined that “[t]he Blissfield PPA
    is incorporated by reference into the purchase agreement.” 
    Id.
     Not just the term “Commercial
    Operation Date,” which the Purchase Agreement does expressly incorporate, but the entire PPA.
    Why the Superior Court needed to reach that conclusion we cannot say, because the only part of
    the PPA that the Superior Court found relevant_the amendment the parties made to the term
    “Plant Site” by changing “Lenawee County” to “Ionia or Gratiot County”_is incorporated into
    the PPA’s definition of “Commercial Operation Date” (through a sort of roundabout reference to
    the term “Plant,” which in turn references the term “Plant Site”). So there was no need to
    contemplate whether the Purchase Agreement incorporated any other parts of the PPA, or the rest
    of it entirely. And to the extent the Superior Court believed that the incorporation of a discrete
    21
    As explained, the Purchase Agreement provides that the earn-out would be
    triggered if “the Blissfield Wind Project achieves Completion of Development and
    Commencement of Construction,” which, with its defined terms fully expanded,
    means that the payment would be due if “the wind project under development in
    Lenawee County, Michigan achieves” either the five milestones specified in the
    Purchase Agreement or the milestones “set forth in the Michigan PPA related to . . .
    [‘the wind project under development in Lenawee, County, Michigan’].” If the PPA
    were transferred to a different wind farm development separating the PPA from the
    development in Lenawee County, that would not create an interpretive disconnect
    between the Purchase Agreement and its incorporation of the PPA’s milestones_it
    would simply mean that “the wind project under development in Lenawee County”
    would not be able to achieve those milestones.34
    term or two from another contract necessarily means that the entire contract has been incorporated,
    we disagree See 11 Richard A. Lord, Williston on Contracts § 30:25, at 234, 238 (4th ed. 1999)
    (“It is not necessary to refer to or incorporate the entire document; if the parties so desire, they
    may incorporate a portion of the document . . . While discussion of incorporation by reference is
    often framed in terms which suggest the complete absorption of one document into another, it is
    important to note that when incorporated matter is referred to for a specific purpose only, it
    becomes a part of the contract for that purpose only, and should be treated as irrelevant for all other
    purposes.”).
    34 Our understanding that a transfer of the PPA to a different wind farm development would
    end any chance that Blissfield Wind Project could meet the PPA’s milestones, which constitute
    one of the two triggers for the earn-out, does not leave the Purchase Agreement vulnerable to earn-
    out-avoiding gamesmanship. The Purchase Agreement required Exelon to “us[e] all commercially
    reasonable efforts and Prudent Industry Practices to . . . complete development and commence
    construction” on Blissfield Wind Project “such that [the Project] would . . . achieve commercial
    operation by the . . . Commercial Operation Milestone Date” in the PPA, App. A319, so only in
    scenarios such as this one, where some unexpected occurrence (like a hostile municipality)
    rendered it commercially unreasonable to continue development at the Lenawee County site, could
    22
    The second reason the Superior Court offered was its view that Exelon’s
    “actions and representations at the time it was seeking to amend the Blissfield PPA”
    showed that Exelon itself believed that the “wind project” was something it could
    move to another site. Among the evidence the court seized upon was the force
    majeure letter that Exelon sent to Consumers Energy shortly after the restrictive
    ordinance was passed in Riga Township, in which Exelon told Consumers that “[t]he
    Force Majeure event [would] continue unless and until these new regulations are
    repealed . . . or the Project is moved to an alternate location.”35 Exelon spoke in
    similar terms to Consumers in a second letter sent shortly thereafter, in which it told
    Consumers that it “ha[d] identified a possible alternative site for the Project in a
    nearby county within Michigan and is currently assessing the feasibility of moving
    the Proj ect to this location.”36 But, of course, these letters do not mean that the Beebe
    Wind F arm was “the wind project under development in Lenawee County,
    Michigan” for purposes of the Purchase Agreement, to which Consumers was not a
    party. They simply recognize that Exelon was hopeful it could identify a substitute
    site that_with Consumers’ consent-could fulfill the role that the Blissfield Wind
    Project was supposed to play, but could not, under the PPA. And Exelon also
    Exelon have moved the PPA and abandoned the Lenawee County development And the notion
    that Exelon might be trying to game the earn-out provision is undermined by the fact that it
    willingly paid Deere earn-out payments for its successful development of the other two Michigan
    Wind Proj ects.

    apparently included a line item for the $14 million earn-out payment to Deere in one
    of its internal valuations of the Beebe Wind Farm, which the Superior Court
    interpreted as suggesting that Exelon_or at least someone in its finance
    department_believed that the “wind proj ect” Was moveable. But this document may
    simply reflect that there was a risk Deere would argue that the Beebe Wind Farm
    counted, Which Exelon believed was prudent to factor into its decision making37
    The questionable value of these documents aside, what is important is that
    they are all parol evidence Extrinsic evidence like this cannot be used “to interpret
    the intent of the parties” or “to vary the terms of the contract” unless the contract
    suffers from some ambiguity.38 But the Superior Court concluded-and we agree_
    that “[t]he Purchase Agreement is unambiguous in its terms relevant to this case.”39
    So why the parol evidence? The Superior Court believed that when a contract
    contains an earn-out provision, a court is allowed to consult “post-closing events and
    circumstances” to “resolve the parties’ rights and obligations under the contract.”4°
    That was error.
    The Superior Court said that when a dispute arises over a party’s entitlement
    to a contractual earn-out payment, “it [is] necessary for the [court] to examine the
    37 See also App. A530 (Deere internal email confirming Deere’s intent to write off the earn-
    out connected to the Blissfield Wind Project).

    post-closing conduct of the parties” to “deterrnine whether the seller [is] entitled to
    the earn-out.”41 That is true enough. But it stands for nothing more than the obvious:
    when a party to a contract claims that the other breached (such as by failing to pay
    an earn-out that was allegedly due), whether a breach has occurred depends upon
    what the parties did (or did not do) after the contract was formed. That evidence
    cannot be used, as the Superior Court did here, as an aid to interpreting the meaning
    of the contract So although the parties’ post-closing conduct is essential to
    determining whether the Beebe Wind Farm met the Purchase Agreement’s definition
    of the “wind project under development in Lenawee County, Michigan,” and, if so,
    whether the Beebe Wind Farm achieved the earn-out triggering milestones, it
    cannot_absent an ambiguity that the Superior Court did not identify-be used to
    determine what the parties meant by “the wind farm under development in Lenawee
    County, Michigan,” and whether they understood it to be tethered to Lenawee
    County.

    For the foregoing reasons, the Superior Court’s grant of` summary judgment
    in favor of Deere is reversed, and this case is remanded with instructions to enter
    judgment in favor of Exelon.42
    42 In light of our conclusion that Exelon does not owe the earn-out payment, We need not
    address the Superior Court’s rejection of the affirmative defenses that Exelon raised in the hopes
    of defraying some or all of that payment
