        NO. D-1-GV-06-000827, HONORABLE JOHN K. DIETZ, JUDGE PRESIDING



                              CONCURRING OPINION


                We withdraw the opinion issued May 23, 2008 and issue the following opinion

and in its place.

                We join with Justice Patterson in the judgment regarding most of the parties’ issues

(as the Court’s recent opinion in CenterPoint Energy Houston Elec., LLC v. Gulf Coast

Coalition of Cities, No. 03-05-00557-CV, ___ S.W.3d ___, 2007 Tex. App. LEXIS 9919

(Tex. App.—Austin Dec. 20, 2007, no pet. h.) controls many of them) but diverge with regard to

whether the Commission’s adjustments to the net book values of the South Texas Project and
the Coleto Creek coal plant violated PURA section 39.252(d).1 We affirm the district court’s

judgment that the Commission lacked statutory authority to make these adjustments. Also, because

Justice Patterson’s more expansive view of the Commission’s power also undergirds her analysis

of the Joint Intervenor’s seventh issue concerning book-value adjustments related to bridge

power-sales agreements,2 we similarly differ in our analysis, though we ultimately join her in the

judgment affirming the Commission and district court regarding that issue.


PURA 39.252(d) and book-value adjustments to STP and Coleto Creek

                This issue turns on a question of statutory construction: simply put, whether an

electric utility’s conduct of a sale of its generation assets can meet the requirements of a

“bona fide third-party transaction under a competitive offering” under PURA 39.262(h)

and nonetheless violate the utility’s duty to mitigate stranded costs through commercially

reasonable means.

                The now-familiar term “stranded costs” under PURA chapter 39 refers generally to

“the portion of the book value of a utility’s generation assets that is projected to be unrecovered

through rates that are based on market prices,” Cities of Corpus Christi v. Public Util. Comm’n,

188 S.W.3d 681, 685 (Tex. App.—Austin 2003, pet. denied) (quoting In re TXU, 67 S.W.3d

130, 132 (Tex. 2001) (Phillips, C.J., concurring)), thereby “stranding” costs of the utility’s prior

investments in generation assets that would have been recoverable under the prior rate-regulated

regime. Id. (observing that “[s]tranded costs are a potential byproduct of Texas’s transition from

the former rate-regulated electricity system to competition”). Among the legislature’s “foundational”

policy goals in PURA chapter 39 was ensuring that incumbent, formerly integrated electric utilities

could recover their stranded costs so as to eliminate this competitive disadvantage they would face

against new market entrants. Id. (“Because the new market entrants would not have these embedded

generation-related costs and opportunity cost reflected in the rate of return, their pricing structure

would tend to be lower than that of incumbent utilities . . . enabl[ing] new market entrants to price

electricity below a level at which incumbent utilities could recover their investments” forcing them

either to “charge uncompetitive higher rates or simply absorb these ‘stranded costs.’”).

                “Conceptually, stranded costs under chapter 39 of the utilities code exist as of the last

day before the opening of retail competition, December 31, 2001 [but] accurate calculation of such

costs could take years, as a utility may not know whether it has been able to recover the millions of

dollars spent on a generation-related asset until it sells the last kilowatt generated by that asset.” Id.

at 691-92 (citing In re TXU, 67 S.W.3d at 147 (Brister, J., concurring)). The legislature opted to

sacrifice some of the certainty and accuracy of a long-term calculation of stranded costs under actual

market conditions (e.g., the extent to which the rates the utility could charge under competitive

conditions during the life of the generation asset ultimately enabled it to recoup its investments in

the asset) in favor of providing “finality regarding the issue to facilitate the transition to a

competitive electricity market by 2008.” Id. at 692. It “mandated that the 2004 true-up calculation

would be the final, controlling calculation of each utility’s stranded costs.” Id. However, the focus

of this calculation remained whether, under actual market conditions, the utility could recover its

stranded costs. In lieu of relying on long-term actual performance of the assets in the competitive



                                                    3
retail electric market, the legislature looked to a measure that would reflect a market judgment of the

assets’ anticipated future performance under that regime—the market value of the generation assets

under the competitive regime. See Tex. Util. Code Ann. § 39.262 (West 2007).

                 Subsection (h) of PURA 39.262 requires that “[f]or the purpose of finalizing the

stranded cost estimate . . . the affiliated power generation company shall quantify its stranded costs”

through one of four prescribed alternative market-based measures of the market value of its

generation assets. See Tex. Util. Code Ann. § 39.262(h).3 The legislature has imposed detailed

requirements and limitations governing the use of each measure aimed at ensuring the integrity of

the underlying market mechanisms. Of relevance here, the “sale of assets” method of valuation may

be used only if an electric utility or its affiliated power generation company has sold some or all of

its generation assets in a “bona fide third-party transaction under a competitive offering.” Id.

§ 39.262(h)(1). The Commission has construed “bona fide, third-party transaction under a

competitive offering” to mean one in which “the seller conducts itself in a manner that a reasonable

person would act in an ordinary commercial transaction without the benefit of stranded-cost recovery

to protect that person’s financial interests.”4 Aspects of such behavior by a seller include “giv[ing]

serious consideration to understanding the market and acquiring competent financial advice,”

“encourag[ing] bidders to participate and negotiate reasonably,” “provid[ing] all bidders equal and

accurate information on the assets,” and “[i]mportantly . . . negotiat[ing] vigorously with potential



        3
          Subsection (i) provides an alternative measure for certain nuclear assets. We agree with
Justice Patterson that this provision is effectively a default that applies in certain situations when the
valuation methods of subsection (h) cannot be utilized.

buyers to obtain a price reflective of the value of the asset.”5 Additionally, the “bona fide aspect of

the transaction required by section 39.262(h)(1),” the Commission has explained, entails “one in

which the seller is sincerely and honestly intent upon obtaining a price for his assets that reflects a

true market value so as to minimize stranded costs” and “does not unduly rely on stranded-cost

recovery,” “is evidenced by the seller’s faithfulness to the twin obligations of both obtaining a true

market value and minimizing stranded costs,” and “comports with reasonable commercial standards

when viewed in its entirety.”6 “In addition to being a bona-fide transaction,” the Commission has

stated, “a sale of assets under PURA § 39.262(h)(1) must also be competitive,” and that a

“competitive offering” denotes one involving “multiple entities all seeking to purchase the same

generation assets at the same time, and all subject to the same set of rules.”7 “At the end of the

competitive sales process, when the seller has focused on one bidder and is negotiating with that

party,” the Commission adds, “the buyer and seller must negotiate vigorously.”8

                 Assuming the company complies with the prescribed requirements for the asset-sale

or other market-based valuation method under PURA 39.262(h), the valuation yielded establishes

the market value of the generation assets that the Commission must employ in its final stranded cost

estimate. See Tex. Util. Code Ann. § 39.262(h)(1)-(4).9 In circumstances where a utility fails to

comply with the requirements for using one of these methods, this Court has recently recognized that

the Commission has limited, implied statutory authority to determine the market value that one of

the statutory methods would have yielded had it been fully complied with. CenterPoint, ___ S.W.3d

at ___, 2007 Tex. App. LEXIS 9919, at *53-54 (implied power derives from “clear legislative

mandate that utilities be allowed to recover their stranded costs” and fact that “nothing in the code

indicates that the failure of a utility to satisfy one of the market-valuation requirements should result

in an automatic denial of the right to recover any stranded costs”); see also State v. Public Util.

Comm’n, No. 03-06-00503-CV, ___ S.W.3d ___, ___, 2008 Tex. App. LEXIS 563, at *23

(Tex. App.—Austin Jan. 25, 2008, pet. filed) (further observing that chapter 39 defines “market

value” as “the value the asset would have if bought and sold in a bona fide third-party transaction

on the open market”) (emphasis added).

                On the other hand, although PURA chapter 39 reflects the legislature’s policy goal

that electric utilities recover their stranded costs as part of Texas’ transition to retail electric

competition, “there were express limitations imposed on this right.” CenterPoint, ___ S.W.3d at

___, 2007 Tex. App. LEXIS 9919, at *10. Utilities are entitled to recover only their “net,

verifiable, nonmitigable stranded costs incurred in purchasing power and providing electrical

generation service,” Tex. Util. Code Ann. § 39.252(a) (West 2007) (emphasis added), and have an

affirmative obligation to “pursue commercially reasonable means to reduce [their] stranded costs,

including good faith attempts to renegotiate above-cost fuel and purchased power contracts or

the exercise of normal business practices to protect the value of its assets.” Id. § 39.252(d); see

Reliant Energy, Inc. v. Public Util. Comm’n, 101 S.W.3d 129, 149 (Tex. App.—Austin 2003),



                                                   6
rev’d on other grounds, CenterPoint Energy, Inc. v. Public Util. Comm’n, 143 S.W.3d 81

(Tex. 2004) (op. on reh’g) (“Compliance with the duty to pursue commercially reasonable means

to mitigate its potential stranded costs is part of what makes stranded costs non-mitigable.”).

The Commission is statutorily empowered to enforce these limitations when calculating an electric

utility’s final stranded-cost estimate. A utility “may not be permitted to overrecover stranded costs

through the procedures established by [PURA 39.262] or through the application of the measures

provided by the other sections of this chapter.” Tex. Util. Code Ann. § 39.262(a). Further, in PURA

39.252(d), the legislature mandated that “the commission shall consider the utility’s efforts under

this subsection [to “pursue commercially reasonable means to reduce its potential stranded costs”]

when determining the amount of the utility’s stranded costs.” Tex. Util. Code Ann. § 39.252(d);

see Reliant, 101 S.W.3d at 147 (observing that PURA 39.252 supplies a statutory incentive for

utilities to maintain or increase the market value of their generation assets, countering potential

incentives to depress market value in order to increase stranded-cost recovery). But the legislature

added an important qualification to this power: “provided, however, that nothing in this section

authorizes the commission to substitute its judgment for a market valuation of generation assets

determined under Section 39.262(h) and (i).” Tex. Util. Code Ann. § 39.252(d) (emphasis added).

               Because PURA 39.252(d) requires the Commission to “consider” a utility’s

stranded-cost mitigation efforts in its final stranded-cost estimate while also prohibiting it from

substituting its judgment for the market valuation of generation assets yielded under PURA

39.262(h) and (i), this Court has deduced that the legislature “impliedly contemplate[d] some sort

of adjustment to book value—the only other component of stranded costs.” Reliant, 101 S.W.3d at



                                                 7
149; see Tex. Util. Code Ann. § 39.251(7) (West 2007) (“‘Stranded cost’ means the positive excess

of the net book value of generation assets over the market value of the assets . . . .”); State v. Public

Util. Comm’n, ___ S.W.3d at ___, 2008 Tex. App. LEXIS 563, at *15 (summarizing stranded-cost

“formula” as “SC = NBV - MV”).

                  Purporting to rely on this authority, the Commission reduced the book value of TCC’s

share in STP and the Coleto Creek coal plant based on what it found to have been TCC’s

commercially unreasonable conduct in connection with its sales of those assets under PURA

39.262(h)(1). The Commission deemed commercially unreasonable what it termed TCC’s failure

to “fully analyze the value” of its STP share before offering it for sale and stated that such actions

would have enabled TCC “to determine whether the bids received from the auction were appropriate,

and . . . cease[] negotiations with bidders if it became apparent that the negotiations were not

producing an appropriate price.” It also found unreasonable TCC’s “bundling” of the Coleto Creek

plant for sale with older gas plants without “explor[ing] other avenues of valuing the gas plants,”

such as selling them for “land, water rights, and scrap.” At the same time, however, the Commission

found that TCC’s sales of both generation assets met the standards for “bona fide third-party

transaction[] under a competitive offering” under PURA 39.262(h)(1). No party to this proceeding

challenges the latter determinations, with the exception of the Joint Appellants’ issue disputing

whether TCC’s sale of its STP share met this standard, and this panel has unanimously rejected

that challenge.

                  The parties dispute whether, as a matter of law, the Commission’s power to adjust

the book value of generation assets based on findings of commercial unreasonableness in failing to



                                                   8
mitigate stranded costs extends to conduct during a sale of those assets that complies with the

“bona fide third-party transaction under a competitive offering” standard of PURA 39.262(h)(1).

TCC urges that “[a] sale in compliance with section 39.262(h)(1) is legally sufficient as a matter of

law because it complies with this statutory divestiture provision.” The Commission and Joint

Appellants insist that any dispute with the Commission’s authority to make book-value adjustments

to account for commercially unreasonable conduct in any context was foreclosed by this Court in

Reliant. TCC would distinguish Reliant as addressing only whether the Commission had some

authority to make book-value adjustments to account for the effects of a utility’s commercially

unreasonable conduct, not whether that authority extended to making such adjustments under the

particular circumstances presented here.

               We agree with TCC that Reliant does not control our disposition of this issue. Reliant

involved a declaratory-judgment action brought by a utility under PURA 39.001(e) challenging the

validity of the Commission’s rule 25.253(e)(4), which implemented section 39.252(d) by authorizing

the Commission to adjust net book value to correct for commercially unreasonable conduct. The

utility argued that the limitation of section 39.252(d)’s final clause—“provided, however, that

nothing in this section authorizes the commission to substitute its judgment for a market valuation

of generation assets determined under Sections 39.262(h) and (i)”—evidenced legislative intent to

ensure an “accurate” stranded-cost figure, as determined by market valuation, and that permitting

any adjustments to book value circumvented that statutory goal. Observing that “the relevant

statutory goal is not calculating an accurate stranded-cost amount, but calculating an accurate

“verifiable, non-mitigable stranded cost[ ]” amount, this Court held that section 39.252(d) “impliedly



                                                  9
contemplates some sort of adjustment to book value” because “the Commission is prohibited from

adjusting the market value of the generation assets as determined under section 39.262(h) and (i).”

Reliant, 101 S.W.3d at 148-49.

               Thus, Reliant merely rejected the broad contention that the Commission lacked any

statutory power under any circumstances to make book value adjustments to correct for what it finds

to have been commercially unreasonable conduct. It did not, contrary to the Commission’s and

Justice Patterson’s suggestions, hold that the Commission has statutory authority to make such

adjustments under any circumstances, much less when the purported commercially unreasonable

conduct occurs during a transaction complying with the “bona fide third-party transaction

under a competitive offering” standard of PURA 39.262(h)(1). Nor does CenterPoint suggest

any such thing.

               In the portion of CenterPoint emphasized by Justice Patterson, the Court addressed

whether the Commission had acted arbitrarily and capriciously in refusing to make certain

book-value adjustments to reflect alleged commercially unreasonable conduct occurring before a

stock sale in attempted compliance with the partial-stock valuation method of PURA 39.262(h)(3).

In upholding the Commission’s ruling, the Court assumed that “[e]ven if [PURA 39.262(d)] allows

the Commission to alter the amount that a utility is entitled to recover if the utility fails to

‘commercially reasonable ways to reduce its potential stranded costs,’ there is no indication from

the words used in that section or in any provision of the utilities code that this power is punitive in

nature” so as to allow book-value adjustments for conduct having no ultimate impact on the amount




                                                  10
of stranded costs. CenterPoint, ___ S.W.3d at ___, 2007 Tex. App. LEXIS 9919, at *82-83

(citation omitted). In this regard, the Court explained:


       any power that the Commission may have [under section 39.252(d)] to alter the
       amount of [stranded-cost] recovery is limited to ensuring that the amount of stranded
       costs that a utility recovers corresponds to the actual costs that the utility incurred as
       a result of deregulation and was not intended to be used for punishing utilities for
       commercially unreasonable behavior. . . . [I]f the commercially unreasonable
       behavior has no financial impact or if the financial impact is either irrelevant to or
       accounted for in the valuation method chosen, then adjusting the amount of recovery
       would be contrary to the legislative directive.


Id. at ___, 2007 Tex. App. LEXIS 9919, at *83. Read in its proper context, nothing in this analysis

implies that the Commission has statutory power to make book-value adjustments for alleged

commercially unreasonable conduct that it deems to impact market price during a transaction

complying with the legislature’s prescribed market valuation methods in PURA 39.262(h).10 In fact,

PURA chapter 39 is to the contrary.

                Considering chapter 39 and its stranded-cost recovery scheme as a whole, we

conclude that the legislature intended that an electric utility’s compliance with the “bona fide

third-party transaction under a competitive offering” standard of PURA 39.262(h)(1) in its sale of

generation assets satisfies, as a matter of law, any duty during the sale to mitigate its potential

stranded costs by commercially reasonable means. We first observe that, as the Commission has

acknowledged in this proceeding, the “bona fide third-party transactions under a competitive

offering” standard of PURA 39.262(h)(1) is itself a standard of commercial reasonableness. That




       10
            We note that Justice Puryear, the author of CenterPoint, joins this opinion.

                                                  11
standard, as noted, serves to ensure that the asset sale yields a valuation that reflects a true market

judgment of the generating asset’s anticipated revenue streams and other factors bearing on its value

in a competitive retail electric marketplace. Conversely, the standard ensures stranded–cost

mitigation by preserving the integrity of the market transaction against any incentives that

might otherwise exist to depress market value in order to increase stranded-cost recovery.

Consequently, the “bona fide third-party transaction under a competitive offering” requirement of

PURA 39.262(h)(1) amounts to a particularized application of an electric utility’s general duty to

mitigate its potential stranded costs through commercially reasonable means. And the fact that the

legislature prescribed these specific standards of commercially-reasonable conduct to govern

sales of generation assets belies the notion that it impliedly delegated authority to the

Commission to enforce some other concept of commercial reasonableness in these transactions.

See Cities of Corpus Christi, 188 S.W.3d at 691-93 (holding that text of chapter 39 and

comprehensiveness of stranded-cost recovery scheme belied legislative intent to impliedly delegate

power to Commission to order refunds of stranded-cost “over-recoveries” as calculated under interim

estimates before 2004 true-up).

                In contending otherwise, the Commission attempts to draw a distinction between the

“overall” commercial reasonableness of an asset sale as a determinant of market value, which it

acknowledges is addressed by section 39.262(h)(1), and “the commercial reasonableness of a utility’s

mitigation efforts under PURA § 39.252(d)” during the conduct of the sale, which it deems

“a separate issue in this proceeding.”11 What the Commission suggests, in other words, is that

                                                  12
PURA chapter 39 imposes a two-tiered duty on electric utilities to mitigate stranded costs through

commercially reasonable means during an asset sale under section 39.262(h)(1)—comply with the

“bona fide third-party transaction under a competitive offering” standard of section 39.262(h)(1) and

ensure that it otherwise “perfectly performs all activities relating to a sale” (as later determined by

the Commission).12 This is not what the legislature has contemplated or required in PURA chapter

39, however. The legislature has required a legitimate market judgment of the generation assets’

value—the price yielded through a “bona fide third-party transaction under a competitive

offering”—and explicitly prohibited hindsight regulatory judgments of whether the price yielded

in such a transaction was “fair,” “appropriate,” or somehow could have been better.                See

Tex. Util. Code Ann. §§ 39.252(d), .262(h).

                Having determined that TCC’s sale of its STP share and the Coleto Creek coal plant

meet the legislature’s prescribed “bona fide third-party transaction under a competitive offering”

standard for calculating the assets’ market value, we conclude that the Commission had no authority

to make book-value adjustments based on its own perceptions as to how or why TCC’s conduct

during the sale should have achieved better prices than the market actually yielded. For this reason,

we agree with the district court that the Commission’s book-value adjustments for purported

“commercially unreasonable” conduct during the asset sales amounted to an improper substitution

of its judgment for a proper market valuation under PURA 39.262(h)(1). See Tex. Util. Code Ann.

§ 39.252(d). Accordingly, we affirm the district court’s judgment as to that issue. Because that

                                                  13
disposition obviates the parties’ issues regarding the specific amounts of the book-value adjustments,

we do not reach them.


Bridge-power-sales agreements

               This issue concerns the scope of any duty by TCC to mitigate its stranded costs in the

interim after it has executed the purchase-sale agreements regarding its generation assets until the

transaction finally closed. During this period, TCC continued to sell power generated by the assets.

The Joint Appellants insisted that TCC should have executed bridge power-sales agreements with

the buyers of the assets. Under the agreements that the Joint Appellants envisioned, the buyers

would have compensated TCC with a higher asset sale price in exchange for the right to sell the

power generated by the assets until the sales were finalized. They urged that the Commission should

reduce the book value of the generation assets by the amount of the margins TCC earned on its

power sales during the interim period, thereby reducing its stranded costs. The Commission rejected

this argument. We affirm the Commission on this issue.

               As previously explained, PURA 39.262(h)(1), governs an electric utility’s duty to

mitigate potentially stranded costs by commercially reasonable means during its sale of generation

assets. When crafting this provision, the legislature was no doubt aware of the complexity of the

asset-sale transactions it was contemplating and the likelihood that such sales would not close

instantaneously. Importantly, the legislature did not require or regulate a particular treatment of

interim power sales, but left those considerations—like myriad others—to be reflected in the market

price yielded by the requisite “bona fide third-party transaction under a competitive offering.”




                                                 14
                Alternatively, the Commission did not misinterpret or misapply PURA § 39.252(d).

The legislature has required that electric utilities pursue commercially reasonable means to reduce

their potential stranded costs. See Tex. Util. Code Ann. § 39.252(d). TCC presented evidence that

bridge power-sales agreements are not common in the industry, and that the effect of such an

agreement would be a wealth transfer to the buyer, effectively enabling the buyer to obtain a return

on an investment that it ultimately might not ever make. The Commission found that the bridge-

power agreements would “increase [the value] artificially,” amounted to “an additional asset[] rather

than maintenance of the value of the plant itself,” and that it was not commercially unreasonable for

TCC not to pursue such agreements.13 We conclude that substantial evidence supports these

findings, and that the Commission’s interpretation and application of section 39.252(d) to this record
