OPINION - FOR PUBLICATION

KIRSCH, Judge

Citizens Action Coalition of Indiana, Inc., Save the Valley, Inc., Sierra Club, and 

Valley Watch, Inc. (collectively, “Intervenors”) appeal the order of the Indiana Utility 

Regulatory Commission (“the Commission”) approving Duke Energy Indiana, Inc.’s 

(“Duke”) request to include power plant construction costs incurred from October 1, 2011 

through March 31, 2012 in a rate adjustment rider.

On appeal, Intervenors raise the following restated issues:

I. Whether the Commission erred when it authorized Duke to pass on to 

ratepayers 100% of Duke’s requested financing costs for the period 

under review when the Commission’s authorization was made in the 

absence of findings of fact and conclusions thereon regarding costs

incurred during a three-month delay; and 

II. Whether the Commission erred by allowing Duke to consider 50% of 

the power plant to be “in-service,” and thereby increase customer 

rates, despite Duke’s admission that the plant had not reached its “InService Operational Date” as that term was defined in a Commissionapproved settlement agreement to which Duke was a party, when such 

determination was made in the absence of Commission findings of 

fact and conclusions thereon.

 

1 Kari A.E. Bennett was absent when the Order at issue was approved on April 3, 2013.

We remand for additional findings.

FACTS AND PROCEDURAL HISTORY2

In 2006, Duke operated a coal and oil-fired generating station at its Edwardsport 

facility in Knox County, Indiana. The facility, which had a capacity of 160 megawatts,

had been placed “in-service” between 1944 and 1951, and was nearing the end of its useful 

economic life. On September 7, 2006, Duke and Southern Indiana Gas and Electric 

Company, d/b/a Vectren Energy Delivery of Indiana, Inc.3filed a Verified Petition with the 

Commission, pursuant to Indiana Code chapters 8-1-8.5, 8-1-8.7, and 8-1-8.8, requesting 

the issuance of applicable certificates of public convenience and necessity (“CPCN”) and 

applicable certificates of clean coal technology for the construction of a 630-megawatt 

capacity, integrated gasification combined cycle (“IGCC”) power plant at the Edwardsport 

location. An IGCC generating facility converts coal into synthesis gas, which is used to 

fuel highly efficient combustion turbines. 

In the Verified Petition, Duke requested: approval of the estimated costs and 

construction schedule of the IGCC Project (“the Project”); authority pursuant to Indiana 

Code section 8-1-8.8-12 to recover construction and operating costs associated with the 

 

2 Oral argument was held on June 25, 2014 at Purdue University’s Krannert Graduate School of 

Management. We extend our thanks to counsel for the quality of the oral and written arguments, for 

participating in post-argument discussions with the audience, and for commuting to West Lafayette. We 

especially thank the Executive Education Program at the Krannert Graduate School of Management for 

their accommodations and the students in the audience for their thoughtful post-argument questions.

Project on a timely basis via applicable rate adjustment mechanisms;4authority to use 

accelerated depreciation for the Project; approval of certain additional financial incentives 

associated with the Project; authority to defer its property tax expense, post-in-service 

carrying costs, depreciation costs, and operation and maintenance costs associated with the 

Project on an interim basis until the applicable costs are reflected in Duke’s retail electric 

rates; and authority to recover other related costs associated with the Project. In re Duke 

Energy Ind., Inc., 43114, 2007 WL 4150583 (Nov. 20, 2007). Duke also asked the

Commission to conduct an ongoing review of the construction of the Project. Id.

Pursuant to Indiana Code section 8-1-1.1-5.1, the Indiana Office of the Utility 

Consumer Counselor (“OUCC”) participated in the proceedings before the Commission on 

behalf of consumers and ratepayers. Intervenors, Duke Energy Indiana Industrial Group 

(“Industrial Group”), and Nucor Steel, a Division of Nucor Corporation (“Nucor”), among 

others, were additional parties to this proceeding. 

On November 20, 2007, the Commission issued its final order in consolidated Cause 

Numbers 43114 and 43114-S1 and made several determinations, including: (1) approval 

 

4 The Commission is required to provide new energy generating facilities with the financial 

incentive of being able to timely recover from ratepayers, through a rate adjustment mechanism, the costs 

incurred in the construction of the facility. Ind. Code § 8-1-8.8-12(a) (emphasis added). An eligible utility 

must apply to the Commission for approval of a rate adjustment mechanism. I.C. § 8-1-8.8-12(b). Such 

application must include at least a schedule for completion of the construction and a statement of the amount 

of capital investment being made by the applicants. I.C. § 8-1-8.8-12(c). As applicable, the Commission

shall allow an eligible business to recover: (1) the costs associated with qualified utility system property; 

and (2) qualified utility system expenses. I.C. § 8-1-8.8-12(d). A retail rate adjustment mechanism 

proposed by a utility may be based on actual or forecasted data. I.C. § 8-1-8.8-12(f). 
5

of CPCNs for the Project under IC 8-1-8.55 and 8-1-8.7;6(2) approval of Duke’s estimated 

costs of $1.985 billion as reasonable to complete the Project; and (3) agreement that 

ongoing review of the construction of and cost recovery for the Project would be conducted 

in semi-annual proceedings. Id. The semi-annual proceedings included a rate adjustment 

mechanism, the IGCC Rider. In each IGCC Rider, the Commission would review the 

progress of the Project’s construction and consider Duke’s request to immediately recover 

construction costs, financing costs, and other operating costs that Duke had incurred during 

the previous six-month period. Once approved, these costs were immediately added to 

customers’ rates. Each six-month period was numbered, with the first being IGCC-1, the 

second IGCC-2, and so forth. In the instant action, Intervenors appeal from the 

Commission’s order (“Order”) in the ninth semi-annual review, IGCC-9.7 

 

5

Indiana Code chapter 8-1-8.5, which addresses Utility Powerplant Construction, prohibits a public 

utility from constructing an electric generating facility without first obtaining from the Commission a 

CPCN stating that public convenience and necessity will be served by constructing the facility. Ind. Code 

§ 8-1-8.5-2. As a condition for receiving this CPCN, the utility must file an estimate of construction costs 

in such detail as the Commission may require. The Commission must review the continuing need for the 

facility under construction and, when requested by the public utility, must engage in an ongoing review of 

the construction progress. Ind. Code § 8-1-8.5-6. Under such a program, the utility must submit, at intervals 

mutually agreed to by the utility and the Commission, a progress report and any revisions in the cost 

estimates for the construction. I.C. § 8-1-8.5-6(a). 

6

Indiana Code chapter 8-1-8.7, which addresses Clean Coal Technology, prohibits an electric 

generating plant from constructing a clean coal technology plant without first obtaining from the 

Commission a CPCN stating that public convenience and necessity will be served by such technology. Ind. 

Code § 8-1-8.7-3. Prior to granting this CPCN, the Commission must approve the estimated costs of 

construction. I.C. § 8-1-8.7-4. Thereafter, the Commission must review the continuing need of the clean 

coal plant under construction and, when requested by the public utility, must engage in an ongoing review 

of the construction progress. I.C. § 8-1-8.7-7. Additionally, at intervals mutually agreed to by the utility, 

the applicant must submit a progress report of the construction as it proceeds and any revisions in the cost 

estimates for the construction. Id.

7 On September 11, 2013, the Commission entered its order in IGCC-10, the subsequent semiannual review covering April 1, 2012 through September 30, 2012. 2013 WL 5275998 (Ind. U.R.C.). 

Intervenors have appealed that order in Case No. 93A02-1310-EX-835. 
6

In May 2008, Duke filed its petition in IGCC-1, which included a request by Duke

to revise the projected cost estimate of the Project from $1.985 billion to $2.35 billion and 

a request for approval to undertake studies related to carbon capture at the Project and for 

cost recovery for such studies. On January 7, 2009, the Commission issued its order in 

IGCC-1 approving: (1) Duke’s increase in cost estimate to $2.35 billion and its ongoing 

review progress report; (2) timely recovery from ratepayers of construction and operating 

costs, including financing, through the IGCC Rider for the six months under review; and 

(3) studies related to carbon capture at the Project and cost recovery for such studies. In re 

Duke Energy Ind., Inc., 431114 IGCC-1, 2009 WL 214580 (Jan. 7, 2009). In the 

subsequent two reviews, the Commission also approved Duke’s cost recovery requests in 

IGCC-2 and IGCC-3.

On November 24, 2009, in connection with IGCC-4, Duke requested approval from 

the Commission to recover from ratepayers the costs it had incurred during the six-month 

period ending September 30, 2009. Duke also requested a subdocket, referred to as IGCC4S1, asking the Commission to approve an increase to the cost estimate for the entire 

project. In re Duke Energy Ind., Inc., 2012 WL 6759528 (Ind. U.R.C., Dec. 27, 2012). 

Under IGCC-4S1, Duke initially requested an increase in the Project’s cost from $2.35 

billion to $2.88 billion including allowance for funds used during construction 

(“AFUDC”). Id. Subsequently, Duke proposed to voluntarily cap the costs that it would 

seek from customers and sought approval of a Project cost estimate of $2.72 billion in 

direct construction costs, plus all associated AFUDC costs on the $2.72 billion for a total 

of approximately $3 billion. Id.
7

On July 28, 2010, the Commission issued its interim order in IGCC-4, approving 

Duke’s six-month costs and the IGCC Rider on an interim basis, pending the outcome of 

IGCC-4S1. On September 17, 2010, Duke, Industrial Group, and the OUCC submitted a 

settlement agreement to the Commission in IGCC–4S1, which set a hard cap cost of $2.975 

billion on the construction costs of the Project. Subsequently, amidst an ethics scandal

involving Duke and the Commission, the settlement agreement was withdrawn. 

About two years later, on April 30, 2012, Duke filed a modified settlement 

agreement in IGCC-4S1 (“Agreement”) to which Duke, Industrial Group, OUCC, and 

Nucor were all parties. Appellants’ App. at 321-32. This Agreement included a $2.595 

billion hard cost cap for construction costs and provided a partial cap on capital costs up 

through the Plant’s in-service date. Id. at 322. The Agreement included conditions that 

Duke had to meet before the Plant would be declared in-service and also stated that the 

“In-Service Operational Date shall not be prior to September 24, 2012.” Id. at 323. 

Intervenors were not signatories to the Agreement in IGCC-4S1 and actively opposed it 

being approved by the Commission.

On December 27, 2012, the Commission issued its final order approving the 

Agreement in IGCC-4S1, again over Intervenors’ objections. The Commission

simultaneously issued final orders in several other IGCC Rider proceedings that were then 

pending, but were essentially concluded: Cause Nos. 43114 IGCC-5, IGCC-6, IGCC-7, 

and IGCC-8. In these Orders, the Commission began implementation of the IGCC-4S1 

settlement. In re Duke Energy Ind., Inc., 2012 WL 6759529, (Ind. U.R.C., Dec. 27, 2012); 

In re Duke Energy Ind., Inc., 2012 WL 6759530 (Ind. U.R.C., Dec. 27, 2012); In re Duke 
8

Energy Ind., Inc., 2012 WL 6759531 (Ind. U.R.C., Dec. 27, 2012); and In re Duke Energy 

Ind., Inc., 2012 WL 6759532 (Ind. U.R.C., Dec. 27, 2012).

On June 8, 2012, Duke filed its Verified Petition in the instant action, IGCC-9, 

requesting:

[T]hat the Commission, for ratemaking purposes, authorize the addition of 

the actual expenditures for its IGCC Project made through March 31, 2012, 

to the value of Petitioner’s property. Petitioner further requests that the 

Commission approve and authorize the requested rate adjustment allowing 

Petitioner to earn a return on said amount, in addition to the return on value 

of its used and useful utility property and on its construction work in progress 

investment previously approved by the Commission. Petitioner also requests 

recovery of certain other applicable costs and credits via the IGCC Rider,

including . . . depreciation, and Indiana Coal Gasification Technology 

Investment Tax Credit, as well as reconciliation of amounts necessary to 

adjust the IGCC Rider charges and credits to actual amounts.

Appellants’ App. at 36-37. That same day, the parties offered written testimony into 

evidence. That evidence was admitted without objection. Duke’s testimony was submitted 

by W. Michael Womack, Vice President of the Project; Jack L. Stultz, General Manager 

II, Regulated Fossil Stations; and Diana L. Douglas, Duke’s Director of Rates. Appellant’s 

App. at 9. Kerwin L. Olson, Executive Director for Citizens Action Coalition of Indiana, 

Inc., submitted testimony, again without objection, on behalf of Intervenors on December 

10, 2012. Id. at 10. The pertinent portions of the testimony will be discussed below.

The Commission held a hearing on Duke’s petition on January 15, 2013. About two 

weeks later, Duke filed its post-hearing argument in the form of a Proposed Order.

Intervenors filed Exceptions to Duke’s Proposed Order on February 21, 2013, setting out 

the following specific legal and factual objections to the relief Duke requested in this case. 

1. Duke is not entitled to recover financing costs for the three[-]month 
9

delay that occurred as a result of events that took place during the review 

period at issue in this case. Duke failed to carry its burden of proof that the 

Project financing costs attributable to this three month delay were reasonable 

and necessary, as required under Indiana Code § 8-1-8.8-12.

2. Duke should not be permitted to increase customer rates by declaring 

50% of the plant “in-service,” given that the plant admittedly did not meet 

the definition of the “In-Service Operational Date” included in the 4S1 

Settlement Agreement and approved by the Commission’s 4S1 final order. 

Duke contends the in-service definition in the Settlement is to be used purely 

for ratemaking purposes. Yet at the same time, Duke’s witness Diana 

Douglas acknowledged that Duke’s proposed “partial” in-service declaration 

will, in fact, increase customer rates.8

Appellants’ App. at 418. 

Duke filed a Reply to these arguments on February 28, 2013. Id. at 466-85. In 

pertinent part, Duke asserted: 

3) no evidence has been presented in this proceeding that the schedule 

update testified to by [Duke’s] witness Mr. Womack was 

unreasonable or caused by imprudence; 

4) the principles of collateral estoppel or issue preclusion do not apply 

to this proceeding, which covers an entirely different time period than 

that reviewed by the Commission in IGCC-4S1; 

5) the determination that a portion of the Edwardsport IGCC Project 

should be placed in[-]service for income tax purposes does not 

contravene the Settlement Agreement approved by the Commission 

in IGCC-4S1, nor does it negatively impact customers;

6) [Duke’s] calculation of its AFUDC is proper and logical, and [Duke] 

 

8

Intervenors raised three objections, two of which they raise on appeal. Intervenors’ third 

objection was:

Under Indiana law, a utility may not earn a return on customer contributed capital. 

Deferred taxes constitute “customer contributed” capital. Consequently, Duke cannot be 

permitted to earn a return on deferred taxes as part of its financing costs accrued as 

allowance for funds used during construction (“AFUDC”). 

Appellants’ App. at 418. 
10

has not and is not earning a return on its deferred tax balance.

Id. at 466-67.

On April 3, 2013, the Commission entered its Final Order in IGCC-9, approving the 

financing costs that Duke incurred during the IGCC-9 review, which included an alleged 

$61 million of financing costs that Duke incurred during the three-month delay. The 

Commission approval allowed Duke to pass along to ratepayers, through the IGCC Rider,

all of the IGCC-9 financing costs including the $61 million.

In its order, the Commission set forth “Discussions and Findings,” but failed to 

make findings regarding the reasonableness of the three-month delay or whether 50% of 

the IGCC Plant was deemed to be in-service. Intervenors now appeal the Commission’s 

order. Additional facts will be supplied where necessary.

DISCUSSION AND DECISION

In IGCC-9, the Commission approved Duke’s construction progress and granted 

Duke’s request to recover from ratepayers all costs incurred from October 1, 2011 through 

March 31, 2012. In its order, the Commission set forth the following “Discussions and 

Findings”:

6. A. Ongoing Review Progress Report for IGCC-9. Mr. Womack testified 

concerning the IGCC Project progress report and issues relating to start-up, 

testing, validation, and commissioning activities and explained in detail the 

schedule delays resulting from the increase in bulk commodity quantities.

He explained the IGCC Project has encountered delays in testing and 

commissioning due to issues that have been uncovered and subsequently 

corrected. Thus, the facts explored in previous IGCC proceedings relating 

to the increased commodity quantities continue to have an impact on the 

IGCC Project through the ongoing review period of this proceeding. Joint 

Intervenors reiterated their prior testimony considered in previous IGCC 

dockets that these delays have been caused by mismanagement of the IGCC 
11

Project.

Joint Intervenors renewed their previous concerns related to the “cascade 

effect” of construction problems and the impact of the “deep conflict”

between GE [General Electric (“G.E.”), Duke’s primary equipment vendor 

for the Project,] and the Company and its impact on the IGCC Project. The 

Commission finds that these concerns of Joint Intervenors have been 

addressed in other proceedings and we are not persuaded that evidence 

presented herein alters those findings. Accordingly, they will not be 

addressed again in the present docket.

We further find that the Company has adequately satisfied the information 

reporting requirements to the Commission for purposes of these review 

proceedings as specified in the IGCC-1 and IGCC-2 Orders and subsequently 

amended in Cause No. 43114 IGCC-8. Accordingly, we approve the 

ongoing progress report for IGCC-9.

B. Ratemaking Issues. Joint Intervenors contend that Duke is not entitled to 

cost recovery in this proceeding and that Joint Intervenors believe CWIP 

[construction work in progress] is inappropriate. However, pursuant to 

Indiana Code ch. 8-1-8.8, and this Commission’s Orders in previous IGCC 

proceedings, the Commission finds no basis to discontinue the recovery 

mechanism for the 1GCC Project it previously found appropriate within the 

statutory construct in Indiana.

Joint Intervenors assert that the Company’s calculation of AFUDC is 

incorrect. Ms. Douglas explained that Petitioner calculated its AFUDC rates 

in conformance with FERC’s general instructions for the computation of 

AFUDC rates (found in the Code of Federal Regulations), which this 

Commission has adopted for use by Indiana electric utilities, and that the 

Company’s calculation does not include accumulated deferred income taxes 

because it is not one of the elements specified to be included in the 

calculation by FERC. She also explained that deferred income taxes are not 

included when calculating AFUDC rates in recognition of the fact that 

plant[,] which has not yet been placed in[ ]service[,] generally will not 

generate cumulative deferred income tax balances because it is not yet 

depreciating. We agree with Ms. Douglas that excluding deferred income 

taxes from the calculation of AFUDC rates is in accordance with the FERC 

instructions we have adopted for use by Indiana electric utilities and, 

therefore, is in accordance with this Commission’s rules. We therefore find 

the Company’s calculation of AFUDC rates to be applied to IGCC 

investment is correct.
12

Ms. Douglas testified as to the updated IGCC Rider and the associated 

calculations and assumptions contained in that Rider. Joint Intervenors did 

not present evidence of any miscalculations or propose any alternative 

calculations. The OUCC found the figures used in the calculation of the 

Rider to be supported by the exhibits of the Company. Based on our review 

of the evidence presented on this issue, we find that Duke’s IGCC Rider, as 

sponsored by the testimony of Ms. Douglas, accurately reflects the net retail 

jurisdictional IGCC Project investment as of March 31, 2012, and that the 

proposed IGCC-9 Rider is accurately calculated and accurately incorporates 

the provisions of the Cause No. 43114 IGCC-4S1 Settlement Agreement. 

We find that the IGCC Project costs, including the actual IGCC Project 

investment incurred through March 31, 2012, up to the amount of the Hard 

Cost Cap and Additional AFUDC, as defined by the IGCC 4S1 Settlement 

Agreement and reflected in the testimony and exhibits of Ms. Douglas, are 

hereby approved consistent with our findings herein.

Ms. Douglas also sponsored Petitioner’s Exhibit C-6 which shows the impact 

of the proposed IGCC Project ratemaking treatment. The monthly bill of a 

residential customer using 1,000 kilowatt-hours will decrease by $0.14 or 

approximately 0.2% with implementation of this factor.

Appellants’ App. at 26-27. 

On appeal, Intervenors contend that it was contrary to law for the Commission to 

pass IGCC-9 costs on to ratepayers without making findings regarding Intervenors’ 

objections that Duke has negatively impacted customers’ rates by being three months 

behind in construction and by prematurely declaring 50% of the Edwardsport Plant to be 

in-service. 

The Indiana Code authorizes judicial review of Commission orders as follows:

Any person, firm, association, corporation, limited liability company, city, 

town, or public utility adversely affected by any final decision, ruling, or 

order of the commission may, within thirty (30) days from the date of entry 

of such decision, ruling, or order, appeal to the court of appeals of Indiana 

for errors of law under the same terms and conditions as govern appeals in 

ordinary civil actions, except as otherwise provided in this chapter and with 

the right in the losing party or parties in the court of appeals to apply to the 

supreme court for a petition to transfer the cause to said supreme court as in 
13

other cases. An assignment of errors that the decision, ruling, or order of the 

commission is contrary to law shall be sufficient to present both the 

sufficiency of the facts found to sustain the decision, ruling, or order, and the 

sufficiency of the evidence to sustain the finding of facts upon which it was 

rendered.

Ind. Code § 8-1-3-1 (emphasis added).

Recently, our Supreme Court set forth the standard of review for the Commission 

order as follows: 

The General Assembly created the Indiana Utility Regulatory Commission 

primarily as a fact-finding body with the technical expertise to administer the 

regulatory scheme devised by the legislature.” N. Ind. Pub. Serv. Co. v. 

United States Steel Corp., 907 N.E.2d 1012, 1015 (Ind. 2009) [hereinafter 

NIPSCO]. The Indiana Code authorizes judicial review of IURC orders as 

follows:

An assignment of errors that the decision, ruling, or order of the 

commission is contrary to law shall be sufficient to present both the 

sufficiency of the facts found to sustain the decision, ruling, or order, 

and the sufficiency of the evidence to sustain the finding of facts upon 

which it was rendered.

Ind. Code § 8-1-3-1 (2012). This amounts to a multiple tiered review. 

NIPSCO at 1016. First, the order must contain specific findings on all the 

factual determinations material to its ultimate conclusions. Id. We review 

the conclusions of ultimate facts, or mixed questions of fact and law, for their 

reasonableness, with greater deference to matters within the IURC’s 

expertise and jurisdiction. Id. (citing McClain v. Review Bd. of Ind. Dep’t of 

Workforce Dev., 693 N.E.2d 1314, 1317-18 (Ind. 1998)). Second, the 

findings of fact must be supported by substantial evidence in the record. Id.

We neither reweigh the evidence nor assess the credibility of witnesses and 

consider only the evidence most favorable to the IURC’s findings. Id.

(quoting McClain, 693 N.E.2d at 1317). Finally, we review whether IURC 

action is contrary to law, “but this constitutionally preserved review is 

limited to whether the Commission stayed within its jurisdiction and 

conformed to the statutory standards and legal principles involved in 

producing its decision, ruling, or order.” Id.

Ind. Gas Co., Inc. v. Ind. Fin. Auth., 999 N.E.2d 63, 65-66 (Ind. 2013) (emphasis added).
14

The parties disagree regarding the extent to which the findings must be set forth in 

the Commission’s order. Intervenors contend, “By simply ignoring the central dispute in 

the case, the Commission failed to satisfy its duty ‘to articulate the policy and evidentiary 

factors underlying its resolution of all issues which are put in dispute by the parties.” 

Appellants’ Br. at 13 (quoting L.S. Ayres & Co. v. Indianapolis Power & Light Co., 169 

Ind. App. 652, 676, 351 N.E.2d 814, 830 (Ind. Ct. App. 1976)). Duke maintains that the 

Commission is not required to resolve all issues that are put in dispute by the parties, but 

instead, the Commission’s order must contain specific findings on all factual 

determinations material to its ultimate conclusions. Appellee’s Br. at 9-10 (quoting L.S. 

Ayres, 169 Ind. App. at 661, 351 N.E.2d at 822). We find the Commission’s order was

deficient under both standards and that the Commission failed to articulate the policy and 

evidentiary factors underlying the issues put in dispute by Intervenors. As we explain 

below, the Commission also failed to make adequate findings on all factual determinations

material to its ultimate conclusions to allow Duke to pass along to ratepayers all of Duke’s 

IGCC-9 costs. 

I. Three-Month Delay and Financial Impact

As part of the IGCC-9 review, Duke requested Commission approval to change the 

IGCC Rider to recover financing costs incurred from October 1, 2011 through March 31, 

2012. Intervenors insist that the Commission’s order, which lacked specific findings on 

the three-month delay, is contrary to law. Specifically, Intervenors contend that the 

Commission was required to make findings regarding whether Duke was entitled to the full 

recovery of its requested financing costs in light of the fact that, during the period under 
15

review, there was a three-month delay in Project testing and a commensurate $61 million 

cost associated with that delay. 

We agree with Intervenors that the findings were insufficient to support the 

Commission’s conclusion that Duke was entitled to recover through the IGCC Rider the 

$61 million in financing charges incurred during the three-month delay in commissioning 

the Plant. The first paragraph of the section titled “Ongoing Review Progress Report for 

IGCC-9,” is merely the Commission’s reiteration of Womack’s and Intervenors’ testimony 

regarding the delay—Womack testified that the delays were caused by the increase in bulk 

commodity quantities, while Intervenors testified that the delays were caused by Duke’s 

mismanagement of the Project. This paragraph contains no findings. In the second 

paragraph of that section, the Commission states that Intervenors renewed their previous 

concerns relating to the “cascade effect” of construction problems and the impact of the 

“deep conflict” between G.E. and the Company and its impact on the IGCC Project. Again, 

this language does not reflect a Commission finding. The only true finding is as follows: 

“The Commission finds that these concerns of Joint Intervenors have been addressed in 

other proceedings and we are not persuaded that evidence presented herein alters those 

findings. Accordingly, they will not be addressed again in the present docket.” Appellant’s 

App. at 26. As we discuss below, the evidence before the Commission did not support this 

finding.

Although the IGCC Project is ongoing, each of the IGCC reviews covers a distinct 

six-month period.9 During the IGCC-9 review, Intervenors focused specifically on a threemonth delay that occurred during the period from October 1, 2011 through March 31, 2012. 

In written testimony, Womack confirmed that, in 2010, Duke set a schedule forecasting

that the Edwardsport Plant would be in-service by September of 2012 and would reach 

“substantial completion” in December of 2012. Appellants’ App. at 59. In November 

2011, one month into the IGCC-9 review period, the in-service date was still projected to 

be September 2012. Tr. at 23-24. However, over the course of the six-month IGCC-9 test 

period, the Project schedule fell behind by three months. This delay was supported by 

Womack’s testimony that within one month of the conclusion of the IGCC-9 test period, 

the projected in-service date was postponed until December 2012 and the “substantial 

completion date” was postponed until March 2013. Id. at 25-26.

Intervenors’ counsel J. David Agnew, recognizing that various delays had plagued 

the Project, reminded Womack that during the IGCC 4-S1 hearings, Womack had testified 

regarding Project delays and cost overruns pertaining to “unexpected quantity increases in 

the Fall of 2009.” Id. at 18. To distinguish the current delay, Agnew asked Womack 

whether the three-month10 delay under this IGCC-9 review was a function of those same 

 

9 Duke also recognizes the distinct nature of these proceedings as reflected by the following 

comment it made in its February 2013 reply to Intervenors’ objections: “[T]he principles of collateral 

estoppel or issue preclusion do not apply to this proceeding, which covers an entirely different time period 

than that reviewed by the Commission in IGCC-4S1.” Appellant’s App. at 467. 

10 During the hearing, Agnew referred to a six-month delay. Noting that by October 31, 2012, the 

IGCC Project was delayed an additional three months, Agnew discussed both of these delays together. The 

delay at issue, however, is the three-month delay that occurred during the six month review in question, 

which ended March 31, 2012.

quantity increases. Id. at 19. Womack responded, “[T]here may have been some residual 

impact from the quantity increases”; however, quantity increases “was not the primary 

reason for the delay.” Id. at 19-20. Womack conceded that the reasons for the three-month 

delay “were different—primarily different than the quantity increases.” Id. Upon further 

questioning, Womack admitted that “primarily, the quantity increases impacted the 

construction period most and then a slight increase on the start-up period,” the latter of 

which was the period at issue. Id. at 21-22. 

Intervenors also introduced evidence that Duke was responsible for the delay 

because the testing problems, and therefore the delay, fell within Duke’s area of 

responsibility. To support this position, Intervenors introduced, without objection,11

monthly Progress Reports that G.E. had prepared during the IGCC-9 period. Id. at 156-57. 

In these Progress Reports, G.E. “blamed the quality—or lack thereof—of Duke’s 

‘commissioning’ activities for these equipment problems and resulting delay.” Appellants’

Br. at 7. Contrary to the Commission’s statement, the Intervenors’ concern of the threemonth delay during IGCC-9 was not “addressed in other proceedings.” Appellant’s App.

at 26. 

As to the financial impact, Intervenors cite to Douglas’s testimony establishing the 

financing costs during the IGCC-9 period. During the Commission hearing, Douglas 

quantified the revenue requirement for financing costs (when grossed up for taxes) as 

 

11 After being specifically asked if she had any objections to these reports being introduced into 

evidence, Duke’s attorney replied that she did not object. Tr. at 156. 
18

roughly $122 million. Tr. at 145-46, 150. Douglas confirmed that to get the per month 

financing charge, the $122 million would be divided by six, which would result in roughly 

$61 million for three months of financing costs. Id. at 150.

Intervenors point to the January 2013 testimony of Douglas, who testified that 

financing costs related to Duke’s construction work in progress (“CWIP”), i.e., financing 

costs recovered through the IGCC Rider (plus an additional “gross up” to factor in the cost 

of taxes) amounted to $20.38 million per month, or roughly $61 million for three months. 

Id. at 145-51 

Duke counters that the Commission properly declined to rely on the G.E. Progress 

Reports to reach its determination because those Reports were “plainly hearsay to the 

extent introduced for the truth of the matter asserted.” Appellees’ Br. at 12. Furthermore, 

even if Intervenors proved imprudent delay, Duke alleges that no evidence was introduced 

during the hearing to quantify the costs of that delay. Duke insists that Douglas did not 

equate $61 million with the delay in the scheduled in-service date, “nor did she calculate 

or quantify the potential impact of any alleged schedule delay on the IGCC-9 rates.” 

Appellant’s App. at 477. Duke finds that Intervenors’ claim on appeal that this was the 

“central dispute in the case” is a fallacy. Appellees’ Br. at 14 (citing Appellants’ Br. at 13).

In its final order, the Commission approved 100% of Duke’s requested financing 

costs for the IGCC-9 review period. Intervenors contend, and even Duke agreed, “The 

Commission did not specifically address Joint Intervenors’ contention that the purported

delay led to financing charges of $61 million.” Appellants’ Reply Br. at 7 (citing Appellees’ 

Br. as 16). Intervenors maintain that Duke cannot cure this defect by arguing that “there 
19

was ‘sufficient evidence’ on which the Commission could have relied in entering its order.” 

Id. at 8 (emphasis in original). If the Commission agreed with Duke, and disagreed with 

Intervenors, regarding the impact of the delay on rates, Intervenors argue that the 

Commission should have made findings to support its determination.12 Id.

We need not find that the three-month delay was the “central dispute” to conclude 

that Commission findings relating to the delay and its impact on ratepayers were “material 

to [the Commission’s] ultimate conclusions.” L.S. Ayres, 169 Ind. App. at 661, 351 N.E.2d 

at 822. We remand this issue to the Commission for findings as to whether the three-month 

delay was chargeable to Duke, and if so, what impact that delay had on Duke’s customers’ 

rates.

In-Service Date

Intervenors also argue that it was contrary to law for the Commission to make no 

findings regarding Duke’s request that 50% of the Plant be declared in-service as of August 

12, 2012, where Duke admitted that the plant had not reached its “In-Service Operational 

Date” as that term was defined in a Commission-approved settlement agreement to which 

Duke was a party, and the resolution of this issue impacted Duke’s customers’ rates. 

Intervenors’ contention arises in the following context. 

 

12 Duke claims that it “provided extensive testimony” to rebut Intervenors’ contention that Duke 

caused the delay. Appellees’ Br. at 5. First, Duke’s witnesses testified that “delays occur as part of every 

construction project, especially a large one such as this, and were not caused by mismanagement.” Id. 

(citing Tr. at 309-10). Second, Womack testified, “the required schedule extension[s] have been driven by 

the circumstances of the Project, caused largely by circumstances outside the Company’s control” and “are 

certainly not the result of Duke Energy mismanagement.” Id. (citing Tr. at 310). Duke reminded this court 

that the G.E. Progress Reports cannot be trusted because they were prepared in anticipation of commercial 

litigation, i.e., a suit by Duke against G.E. Id. Because Duke made these rebuttals, the Commission should 

have made findings regarding the impact of the delay and resulting financing costs.

In her written testimony, Douglas explained the financing, depreciation, and other 

costs that Duke proposed to immediately pass through to ratepayers by means of the IGCC 

Rider. In her corrected testimony, filed four months later, Douglas added the following 

three sentences:

[Duke] has determined that approximately half of the Edwardsport IGCC 

plant (consisting primarily of the power block, including the gas CTs, 

HRSGs, and steam turbine) should be declared to be in-service as of August 

1, 2012, for income tax purposes, which will produce bonus depreciation in 

2012 sufficient to prevent the use of the Section 199 deduction in 2012. The 

remainder of the plant is expected to be declared in-service for income tax 

purposes in 2013. [Duke’s] external auditors will be reviewing the income 

tax in-service decision at year-end. 

Appellants’ App. at 265-66 (emphasis added). Douglas offered no explanation regarding 

how Duke’s declaration of 50% in-service as of August 1, 2012, was consistent with the 

Agreement’s definition that September 24, 2012 was the earliest that the Plant could be 

deemed in-service. On cross-examination Douglas claimed that the Agreement was not 

violated because its language was meant to limit Duke’s ability to declare the plant inservice for ratemaking and accounting purposes, but not for tax purposes.13

 Tr. at 127-29. 

The Commission, however, had conflicting evidence on this issue from Douglas 

herself where, in her written rebuttal, Douglas admitted that the in-service declaration 

would not only affect Duke’s taxes, it would also have an accounting and ratemaking effect

in IGCC-9, saying, “Mr. Olson is not correct, however, that this determination does not 

 

13 However, Douglas admitted that the Agreement’s definition relating to in-service makes no 

distinction between in-service for ratemaking purposes and in-service for tax purposes. Appellants’ App. 

at 209. It is a well-established principle of Indiana law that any ambiguities in a contract are to be strictly 

construed against the drafter. Heartland Crossing Found., Inc. v. Dotlich, 976 N.E.2d 760, 763 (Ind. Ct. 

App. 2012). Duke, as a signatory to that Agreement, had a measure of control over the terms, and 

Intervenors opposed the Agreement and therefore did not draft any of its terms.

affect the accounting or the rates the Company is proposing in IGCC-9.” Appellants’ App. 

at 405. When asked at the hearing to explain the impact this partial in-service declaration 

would have on customer rates in IGCC-9, Douglas explained: “They were higher - the 

rates were higher than they would have been had we been able to utilize the Section 199 

deduction.” Tr. at 120. Intervenors’ attorney asked, “So am I correct that the declaration 

of in-service does cause rates to be higher than they otherwise would be,” Douglas 

responded, “Yes, in this particular proceeding.” Id. at 122. In other words, by declaring 

the Plant partially in-service, Duke has caused retail rates to rise.

Intervenors highlight that Douglas did not disclose until the hearing in January 2013, 

that declaring the Plant partially in-service would increase retail rates. Id. For that reason, 

Intervenors, assuming that the partial in-service would not impact rates or accounting, 

initially took no position on this issue. Appellants’ App. at 350. 

Douglas’s belated revelation that customer rates within the IGCC-9 period would 

increase as a result of Duke’s decision to declare the Plant partially in-service, placed 

Intervenors at a distinct disadvantage. First, the soonest Intervenors could object to this 

change in in-service date was in their exceptions to Duke’s proposed order. Second, 

Intervenors were unable to conduct discovery to determine the long-term rate implications 

of this premature in-service declaration. Accordingly, because of the lateness of Douglas’s 

revelation, Intervenors recommended that any increase to Duke’s IGCC Rider rates 

attributable to the in-service declaration should be approved by the Commission only on 

an “interim” basis, i.e., subject to possible refund after the long-term ratemaking 

implications could be evaluated. Appellants’ App. at 438. The Commission neither 
22

accepted nor rejected this recommendation. Instead, the Commission simply ignored the 

in-service issue entirely. In its final order, the Commission made no reference to Douglas’s 

testimony on cross examination, nor to the fact that Intervenors had changed their position 

in response to Duke’s change in position. Instead, the Order simply summarized 

Intervenors’ initial position - i.e., taking no position, so long as customer rates would not 

be impacted - without ever addressing the evidence admitted at the hearing or Intervenors’ 

post-hearing arguments based on that evidence.

Here, the Commission reached no conclusion and made no findings on whether or 

how the Plant could be declared 50% in-service for ratemaking purposes. “The subject 

matter of the regulatory process is too complex to permit the judicial non-expert any clear 

insight concerning the legal and factual issues which the Commission thought ‘material’ 

to its decision.” L.S. Ayres, 169 Ind. App. at 676, 351 N.E.2d at 830. The declaration of 

in-service was pertinent to the ratemaking treatment of Duke’s request under IGCC-9. 

Neither during the formal hearings nor in the Commission’s final written order was any 

attempt made to articulate the reasons underlying the Commission’s apparent acceptance 

of Duke’s request that the 50% of the Plant be deemed to be in-service. “Since the record 

is clearly insufficient to disclose the factors considered, we are incapable of determining 

that the considerations which actually motivated the Commission’s decision were 

reasonably related to the discharge of its statutory duty.” L.S. Ayres, 169 Ind. App. at 677, 

351 N.E.2d at 830. We must remand this portion of the proceedings to the Commission 

for a clear statement of the policy and evidentiary considerations underlying its 

determination regarding Duke’s request that 50% of the Plant be deemed to be in-service. 
23

We remand to the Commission for actions consistent with this opinion. 

Remanded for additional findings.
