## Case Summary

[1] 

### As required by statute, Southern Indiana Gas & Electric Company d/b/a Vectren Energy Delivery of Indiana, Inc. (“Vectren South” or “Petitioner” ), filed a petition with the Indiana Utilit y Regulatory C ommission (“Commission”) seeking approval of its Electric Demand Side Management (“DSM”) Plan for 2016

- 2017 (“Plan” ). The Plan outlined Vectren South’sCourt of Appeals of Indiana | Memorandum Decision 93A02

### energy - efficiency (“EE”) programs and their budgets and costs, including lost revenues resulting from r educed demand for electricity. Indiana law requires the Commission to allow an electricity supplier to recover reasonable lost revenues associated with an energy

- efficiency plan. The Commission held an evidentiary heari ng and issued an order purporting t o find the Plan to be reasonable i n its entirety but limiting lost revenue recovery to four years or the
life of the energy - effi c iency measure, whichever is less, or until rates are implemented pursuant to a final order in Vectren South’s next base rate ca se, whichever occurs earlier.

[2] 

### Vectren South now appeals, arguing that the Commission erred in finding the Plan to be reasonable in its entirety but capping lost revenue recovery at four years. Vectren South also argues that the cap is arbitrary and capricious because the Commission made no specific factual findings that the cap would allow for the recovery of reasonable lost revenues . We agree on both counts and therefore reverse and remand for further proceedings.



## Facts and Procedural History

[3] 

### Vectren South is a public utility based in Evansville that “provides electric utility service to approximately 140,000 customers in six counties in southwestern Indiana.” Appealed Order at 2. In June 2015, Vectren South filed a petition with the Commissi on seeking approval of the Plan p ursuant to Indiana Code Section 8

### A retail rate adjustment mechanism proposed by an electricity
s upplier under this section to implement the timely recovery of program costs (including reasonable lost revenues) may be based on a reasonable forecast, with consideration given to the electricity supplier’s historical lost revenue forecasting accuracy

. I f forecasted data is used, the retail rate adjustment mechanism must include a reconciliation mechanism to correct for any variance between the forecasted program costs (including reasonable lost revenues and financial incentives) and the actual program co sts (including reasonable lost revenues and financial incentives based on the evaluation, measurement, and verification of the energy efficiency programs under the plan).

.... (q) The commission shall adopt:

### Citizens Action Coalition of Indiana, Inc. (“CAC”), was allowed to intervene
in Vectren South’s proceeding . In November 2015, the Commission held an evidentiary hearin g at which Vectren South , CAC, and the Indiana Office of Utility Consumer Counselor (“OUCC”) appeared and presented evidence

. In March 2016, the Commission issued a twenty

- eight

- page order , which reads in relevant part as follows :

6. Vectren South 2016

- 2017 Plan. The 2016

- 2017 Plan includes the following DSM programs, the majority of which are current programs ...: [residential lighting, home energy assessment and weatherization, appliance recycling, and smart thermostats , as well as commercial and industrial new construction and retrofit programs , among others].

7. Evidence.
[ T he Commission summarized the often conflicting evidence and recommendations presented by Vectren South, the OUCC, and CAC, including those regarding lost revenues and cost r ecovery

. The accuracy and adequacy of these findings are not at issue here. ]

8. Discussion and Commission Findings. Vectren South requests approval of its Energy Efficiency Plan and authority to recover program costs, lost revenues, and performance inc entives associated with the 2016

....
B. Reasonableness of the 2016

- 2017 Plan. Having determined that Vectren South has submitted an EE plan as required by Section 10(h), Section 10(j) identifies ten factors the Commission must consider in determining its overall reasonableness

.... For the reasons set forth below, we find that Vectren South's 2016

- 2017 Plan is reasonable and should be approved.

....
iv. EM&V. Evaluation for all programs in the Plan will be conducted by an independent evaluator every year for the prior year's prog rams

....

.... Based on the evidence presented, we find that Vectren South’s proposed EM&V procedures to independently verify the results of its proposed programs and the estimated EM&V costs are reasonable. Petitioner shall file its annual evaluation in its DSMA proceeding.

....
viii. Lost Revenues and Financial Incentives. Petitioner’s requested lost revenues and financial incentives are discussed in detail below.

### Because we have found Vectren South’ s 2016

- 2017 Plan is reasonable, we must consider whether Petitioner’s request for financial incentives and lost revenues associated with its EE programs is reasonable. We also note that 170 IAC 4

- 8 authorizes the provision of financial incentives and lost revenues that the Commission finds reasonable for DR programs. Accordingly, we consider them together.

i. Lost Revenues. Vectren South seeks to recover lost revenues associated with its 2016

- 2017 Plan in the same manner in which it has been authorized to recover lost revenues associated with its DSM programs previously. Both the OUCC and CAC generally oppose Petitioner’s recovery of lost revenues.
Both the OUCC and CAC argue that lost revenues should be authorized only if Petitioner has experienced a reduction in kWh [kilowatt hour] sales compared to the kWh sales used to set rates in its last base rate case. The OUCC presented evidence that Vectren South’s sales had exceeded test year sales for calendar years 2010 through 2014. However, on rebuttal , Vectren South pointed out that the increase in sales was attributable to industrial customers who had opted out of EE and that this trend is expected to reverse due to a large industrial customer's plans to begin self

- generating in 2017. [ Vectren Utilit y Holdings, Inc.’s Vice President of Customer Energy Solutions Robert C. Sears] testified that should sales continue to remain flat to declining, implementation of the EE programs will cause lost revenues that are not covered by load growth.
As we have pr eviously explained, because the purpose of lost revenue recovery is to return the utility to the position it would have been in absent implementation of DSM, simply eliminating lost revenue recovery when sales are higher than the levels used to develop a u tility’s current base rates would be contrary to this purpose. Recovery of lost revenues is intended as a tool to remove the disincentive a utility would otherwise face as a resultCourt of Appeals of Indiana | Memorandum Decision 93A02

### of promoting DSM in its service territory.

... The OUCC and CAC appear to be primarily concerned with what [CAC consultant Natalie Mims] termed the pancake effect, which is caused when lost revenues caused by EE investments in different years aggregate. For example, if the average weighted measure life is ten years for an EE meas ure then the utility company, assuming there is no rate case in the interim, would still be collecting lost revenues in 2025 for measures installed in 2016, along with lost revenues for measures installed during 2017

- 2025. [ 6 ]


### The proposed annual budgets f or the 2016

- 2017 Plan show lost revenue as a percentage of the total budget is 11.8% in 2016 and 12.5% in 2017. Ms. Mims noted that Petitioner is requesting $2.5 million in lost revenues, but that this amount does not appear to include the legacy lost rev enues, incremental or cumulative lost revenues for 2015 through 2017 that Petitioner has requested or is receiving, or the total amount of lost revenues that Vectren South has recovered.

6 According to the Commission, Mims testified that Vectren did not provide a breakdown of lost revenue by program or year , or any evidence that it will under

- recover authorized costs due to the impacts of its EE programs. She testified it is unreasonable to recover lost revenues if there is no evidence that t he revenues are actually lost. She also testified that lost reven ue recovery is meant to be a short

- term solution to address revenue loss in between rate cases. She stated that in the absence of a rate case, Vectren South will continue to add lost revenues from prior years to existing years for EE measures that are sti ll in service, which is known as the Pancake Effect. Accordingly, she recommended that if recovery of lost revenue is allowed, it should be limited to three years or the life of the measure, whichever is shorter, to avoid the Pancake Effect. She indicate d that the rationale for a cap of three years of lost revenue can be found in [Senate Enrolled Act 412, enacted as Section 10], which requires the utilities to submit EE plans at least once every three years. Appealed Order at 11. In Vectren South’s rebut tal, Sears disagreed with Ms. Mims that the Pancake Effect warranted limiting lost revenues because the lost revenues reflect a history of successful EE and DSM programs that produce significant savings each year. Mr. Sears testified that the average life of the weighted program savings in the Plan is 6.6 years with 31% of the program savings having an average life of three years or less for the residential sector; an average life of the weighted program savings of 10.9 years for the commercial sector and 8.5 years for the overall portfolio.

### Although we have previously approved lost revenues over a measure’s life or until a utility’s next base rate case, whichever is shorter, Ms. Mims’ and the other parties’ concerns with pancaking and the increased length of time between base rate cases for utilities in Indiana raise a valid concern. Clearly, pancaking of lo st revenue is much less of an issue in an environment where a utility comes in regularly, i.e., every three to five years, for a base rate case. When the Commission’s DSM Rules were adopted in the early 1990’s, the previous 20 years was characterized by r outine and sometimes almost back

- to

- back rate case filings where utilities’ rates were reset on a regular basis. Consequently, recovery of lost revenues at that time was viewed as a tool of limited duration until the utility filed its next base rate
case in the not too distant future. However, in the years after adoption of the DSM Rules, utilities have been staying out for ten or more years before filing for a rate case. E.g., Indianapolis Power & Light , 19 years between Cause No. 38664 (IURC 8/23/95) a nd pending Cause No. 44576; Southern Indiana Gas & Electric Co. , 12 years between Cause No. 39871 (IURC 6/21/95) and Cause No. 43111 (IURC 8/15/07); Duke Energy Indiana, Inc. , last rate case was filed 13 years ago in Cause No. 42359 (IUR C 5/18/04, rh’g denied 7/28/04).
Because we believe the parties raise a valid con cern, we find that Vectren South’ s lost revenue recovery should be limited to: (1) four years or the life of the measure, whichever is less, or (2) until rates are implemen ted pursuant to a final order in Vectren South’ s next base rate case, whichever occurs earlier. We note that the CAC also requested that the Commission initiate some type of formal process to develop a standard methodology for Indiana utilities to calcula te lost revenues for an EE measure. Because Section 10 authorizes the recovery of reasonable lost revenues to utilities with an approved EE plan and Section 10(q) requires the Commission to adopt rules implementing the requirements of Section 10, we fully expect that this issue will be addressed in that future rulemaking.Court of Appeals of Indiana | Memorandum Decision 93A02

Commission orders by this Court

. The review involves multiple tiers. Id . “ On the first level, it requires a review of whether there is substantial evidence in light of the whole r ecord to support the Commission’s findings of basic fact. Such determinations of basic fact are reviewed under a substantial evidence standard, meaning the order will stand unless no substantial evidence supports it. ” Id

### “ At the second level, the order must contain specific findings on all the factual determinations material to its ultimate conclusions. ” I d . We review the Commission’s conclusions of ultimate facts for reasonableness, the deference of which is based on the amount of expertise exercised by the agency. I d . If the order involves a subject within the Commission’s special competence, we should give it greater deference; if the subject is outside the Commission’s expertise, we give it less deference. I d

. Findings of fact are important because they help us understand the Commission’s reasoning and policy judgments and allow for a reasoned and i nformed basis of review, which decreases the likelihood that we will substitute our judgment on complex evidentiary issues and policy determinations best left to an agency with technical expertise.

### Further, requiring findings of fact helps the Commission avoid arbitrary and capricious action. Id

.

[7] 

### “ Additionally, an agency action is always subject to review as 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 invo lved in producing its decision, ruling, or order. ” U.S. Steel , 907 N.E.2d at 1016. “ Courts should consider a statute in its entirety, keeping in mind the subject i t addresses and the legislature’ s apparent objective in enacting it. ” In re Dunn , 848 N.E. 2d 310, 316 (Ind. Ct. App. 2006).
The best indication of legislative intent is the statutory language, given its plain and ordinary meaning

. Where the language of a statute is clear and unambiguous, courts should apply the statute without resort to furthe r aids of statutory construction. It should be presumed that the legislature did not intend an absurd, inconvenient, or unjust result.

Id . (citations and quotation marks omitted). We give considerable deference to an interpretation of a statute by an adm inistrative agency charged with administering the statute, but that interpretation is not binding on us when it is incorrect or if the legislative intent is obvious.

### In challeng ing the Commission’s order in this case, Vectren South makes several interrelated arguments , one of which is that the Commission erred as a matter of law by approving its “energy

### By cappin g lost revenue recovery at four years, the Commission implicitly found Vectren South’s lost revenue recovery proposal to be unreasonable

. 9

[9] 

### Vectren South also argues that the Commission’s four

We reiterate that an administrative agency may not make rules or regulations inconsistent with the statute it is administering.

- year cap proposal [by CAC] .” Appellant’s Br. at 35, 36, 37 ; n.6 supra . Indeed, as Ve ctren South points out, the financial effect of the four

10 The Commission observ es that “this is the first plan submitted by Vectren [South] under the new statutory framework in Section 10” and that “[a]n agency may change its course and is not forever bound by prior policy or precedent” as long as it explains its reasons for the chan ge .

11 Vectren South observes that althoug h the Commission expressed “conce rn” about the pancaking of lost

revenue recovery , it failed to explain “why it believes pancaking is bad ” or “why the amount of pancaking that will occur with a 4

- year cap is reasonable, but the amount that will occur with a smaller or larger cap is not.” Appellant’s Br. at 39. On page 17 of its appellate brief, t he Commission quotes from a document that Mims cited regarding the alleged difficulty of tracking the pancake effect over time, but the Commission did not specifically rely on this document in its order or specifically find that the independent EM&V required by statute (and approved by the Commission) is unable to adequately account for this effect. The Commissio n add resses EM&V on pages 18 through 20 of its brie f, but this is too little, too late.

12 The Commission notes that it “similarly capped lost revenue recovery at four years” in two recent orders involving other utilities and that neither utility appealed. Appellee’s Br. at 24. The legal actions or inactions of other utilities are irrelevant here.

### Consequently, we reverse the Commission’s order and remand for furthe r proceedings consistent with this opinion. On re mand , the Commission may either (1) issue specific factual findings to justify its implicit determination that
Vectren South ’s lost revenue reco very proposals are unreasonable, determine that the Plan is not reasonable in its entirety pursuant to Section 10(m ) , and allow Vectren South to submit a modified plan within a reasonable time ; or (2)
issue specific factual findings to justify a determination that the Plan is in fact reasonable in its entirety purs uant to Section 10(k) and allow Vectren South to

recover reasonable lo st revenues in accordance with the Plan

- 6(c) provides that “the approval of a lost revenue recovery mechanism shall not constitute approval of a specific dollar amount, the prudence or reasonableness of which may be debated in a future proceeding before the commission.” According t o the Commission, Sears testified that Vectren South takes a conservative approach to its projected lost revenues to ensure Petitioner is not over

collecting lost revenues from customers. Any over/under collection variance will be recovered in Petitioner’s next DSMA filing. He further testified that forecasted program costs will be reconciled against actual results based on EM&V of the EE programs under the Plan. Appealed Order at 6. The Commission made no findings regarding Vectren South’s historical los t revenue forecasting accuracy or reconciliation mechanism as mentioned in Section 10(o).

15 We need not pass upon the wisdom of the Commission’s justification of a four

- year cap based on the trend toward less frequent base rate cases. We note, however, th at another panel of this Court recently stated that rate cases are “ expensive, time consuming, and sometimes result in large, s udden rate hikes for customers.” NIPSCO Indus.
