Brown, Judge.
[1] Southern Indiana Gas & Electric Company d/b/a Vectren Energy Delivery of
Indiana, Inc. (“Vectren South” or “Petitioner”) filed a petition with the Indiana
Utility Regulatory Commission (“Commission”) seeking approval of its energy-
efficiency Electric Demand Side Management (“DSM”) Plan for 2016-2017
(“Plan”). Citizens Action Coalition of Indiana, Inc. (“CAC”) intervened in the
proceeding. The Commission held an evidentiary hearing and issued its
decision that approved the Plan but limited Vectren South’s lost revenue
recovery. Vectren South appealed, arguing that the Commission erred when it
found the Plan to be reasonable in its entirety but then capped lost revenue
recovery at four years. Vectren South further argued that the cap was arbitrary
and capricious because the Commission made no specific factual findings that
the cap would allow for the recovery of reasonable lost revenues. We agreed on
both counts, reversed the Commission’s order in part, and remanded the case to
the Commission for additional findings. S. Ind. Gas & Elec. Co. v. Ind. Util. Reg.

appeals from the Commission’s Order on Remand, raising the following issues
which we consolidate and restate as follows:
I. Whether the Commission’s Order on Remand is contrary to
law;
II. Whether the Commission’s Order on Remand impermissibly
deviates from precedent; and
III. Whether the Commission’s Order on Remand is supported
by substantial evidence.
We affirm.
Facts and Procedural History
[2] 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. In 2015, the General Assembly passed a statute, Indiana Code § 8-1-
2
8.5-10 (2015) (“Section 10”), requiring electricity suppliers to periodically
present to the Commission energy-efficiency (“EE”) plans, goals, and
3
programs for approval by the Commission beginning no later than 2017. See
Ind. Code § 8-1-8.5-10(h). The statute specifically provides as follows:
2
“Electricity supplier” means a public utility “that furnishes retail electric service to customers in Indiana.”
Ind. Code § 8-1-8.5-10(a). The term does not include a municipally owned utility and certain other
corporations. Id.
3
“Energy efficiency” means “a reduction in electricity use for a comparable level of electricity service.” Ind.
Code § 8-1-8.5-10(b). “Energy efficiency goals” means “all energy efficiency produced by cost effective plans
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 3 of 28
(h) Beginning not later than calendar year 2017, and not less than
one (1) time every three (3) years, an electricity supplier shall
petition the commission for approval of a plan that includes:
(1) energy efficiency goals;
(2) energy efficiency programs to achieve the energy
efficiency goals;
(3) program budgets and program costs; and
(4) evaluation, measurement, and verification

evaluation, measurement, and verification.

subsection to the commission for a determination of the overall

proceeding or as an independent proceeding.
that are: (1) reasonably achievable; (2) consistent with an electricity supplier’s integrated resource plan; and
(3) designed to achieve an optimal balance of energy resources in an electricity supplier’s service territory.”
Ind. Code § 8-1-8.5-10(c). “Energy efficiency program” or “program” means “a program that is: (1)
sponsored by an electricity supplier; and (2) designed to implement energy efficiency improvements. The
term does not include a program designed primarily to reduce demand for limited intervals of time, such as
during peak electricity usage or emergency conditions.” Ind. Code § 8-1-8.5-10(d).

“Evaluation, measurement, and verification (EM&V) is the collection of methods and processes used to
assess the performance of energy efficiency activities so planned results can be achieved with greater certainty
and future activities can be more effective.” DEPT. OF ENERGY, EVALUATION, MEASUREMENT, AND

In determining the overall reasonableness of the plan, the Commission is required to consider ten factors.

[3] As an incentive for participation, the General Assembly included provisions
within the statute allowing electricity suppliers, such as Vectren South, to
recover certain costs associated with their EE plans, including lost
6
revenues. See Ind. Code § 8-1-8.5-10(o) (“If the commission finds a plan
submitted by an electricity supplier under subsection (h) to be reasonable, the
commission shall allow the electricity supplier to recover or receive the
following: . . . (2) Reasonable lost revenues.”). In other words, and as
explained by Vectren South: “When the Commission approves an energy-
efficiency plan, [Ind. Code § 8-1-8.5-10(o)] requires it to approve an adjustment
to the utility’s electric rate, the amount charged to consumers, to compensate
the utility for lost revenues it would have received without these programs
designed to [lower energy consumption and, ultimately,] reduce its sales.”
Appellee’s Brief at 9.
[4] On June 29, 2015, Vectren South filed a petition with the Commission seeking
approval of its Plan, which outlined Vectren South’s EE programs and their
budgets and costs and included lost revenues resulting from reduced demand
for electricity. On July 6, 2015, CAC filed a petition to intervene, which was

Lost revenues can be described as: “an estimation of the amount of lost sales attributable to the energy
efficiency programs. . . .” Exhibits at 19. According to Vectren South, “the purpose of lost revenue recovery
is to return the utility to the position it would have been in absent the implementation of the EE measures.”

granted on August 3, 2015. The Commission held an evidentiary hearing and,
on March 23, 2016, it issued an order (“First Order”) finding the Plan to be
reasonable in its entirety but limiting lost revenue recovery to “four years or the
life of the [EE] measure, whichever is less, or. . . until rates are implemented
[8]
pursuant to a final order in Vectren South’s next base rate case, whichever
occurs earlier.” Appellant’s [Vectren South] Appendix 2 at 31.
[5] Vectren South appealed the First Order, 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 argued that the cap was arbitrary
and capricious because the Commission made no specific factual findings that
the cap would allow for the recovery of reasonable lost revenues. On March 7,
2017, this Court issued a memorandum decision, agreeing with Vectren South
on both counts. S. Ind. Gas & Elec. Co., No. 93A02-1604-EX-914. We reversed
a portion of the First Order and remanded to the Commission with instructions
that it could either:
(1) issue specific factual findings to justify its implicit
determination that Vectren South’s lost revenue recovery
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
pursuant to Section 10(k) and allow Vectren South to recover
reasonable lost revenues in accordance with the Plan.
Id. at 7.
[6] On remand, Vectren South presented a revised lost revenue recovery proposal
(“Revised Lost Revenue Proposal”) that was described in the Commission’s
Order on Remand through testimony provided by Rina H. Harris (“Ms.
Harris”), Director of Energy Efficiency for Vectren Utility Holdings, Inc., at an
evidentiary hearing held by the Commission on September 5, 2017:
Ms. Harris described Vectren South’s [Revised Lost Revenue
Proposal as basing] lost revenues on: (1) the weighted average
[9]
measure life (“WAML”) of the Plan; and (2) a 10% reduction
in annual savings. Using this method, Vectren South would
recover the reasonable amount of lost revenues associated with
the WAML of its EE programs or the measure life, whichever is
less. The WAML of the portfolio would be re-evaluated and
adjusted with each EE filing. [Ms. Harris] said that in using this
approach, Vectren South first determines the weighted average
life of each program by weighting the energy savings for each
9
“Measure” is defined in pertinent part as “[s]pecific energy efficiency activities or equipment.” DEPT. OF
ENERGY, ENERGY EFFICIENCY & RENEWABLE ENERGY 1, https://www.energy.gov/sites/prod/files/2014/
05/f16/ what_is_emv.pdf (last visited Jan. 15, 2019).
“Measure life” is widely defined as “the average/median life over many data points, or customer
experiences, of a particular EE program. It takes into consideration variations in the useful life of an EE
measure among different types of customers by developing an average. [For example, a]n LED could last 5
years in one home, 11 years in another and 30 years in another – with an average of 15 years.” Exhibits at
27.
Weighted average measure life (“WAML”) “is the average life [of a measure or a program], weighted by
savings in years.” Id. at 24.
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 7 of 28
measure included in the program. Next, Vectren South
calculates the weighted average measure life of a portfolio by
weighting the energy savings of each program included in the
portfolio. To determine individual measure lives, Vectren South
[10]
uses the latest Indiana Technical Resource Manual (“TRM”)
for evaluation. Ms. Harris stated that capping recovery of lost
revenues based upon WAML is reasonable because it limits lost
revenue recovery based on the average equipment life and
measure persistence of the entire program plan. In addition, only
90% of annual savings would be recovered, reflecting the
statistical certainty EM&V providers can obtain for energy
savings.
Appellant’s Appendix Volume 2 at 10-11. Vectren South maintained that,
under the Revised Lost Revenue Proposal, it was not seeking to recover its
estimate of $34.3 million in lost revenue or sales, but rather “only about $26
million, or approximately $2.9 million per year.” Appellee’s Brief at 28.
[7] CAC argued for Vectren South’s lost revenue collection to be the lesser of four
years or the Plan’s measure life. A witness for CAC, Karl R. Rábago (“Mr.
Rábago”), the principal of Rábago Energy, LLC, testified that any lost revenue

four years to be reasonable. He compared the dollar amounts between Vectren
South’s original lifetime lost revenue recovery proposal, the Revised Lost
Revenue Proposal, and CAC’s proposal to cap lost revenue recovery at four
years or the life of the measure, whichever is shorter. He determined that,
under Vectren South’s original lost revenue recovery proposal, ratepayers
would pay $34.3 million in lost revenues for a program that costs $16.8 million
to implement. He maintained that although the total amount of lost revenues
under the Revised Lost Revenue Proposal would be less, $25.9 million, this
amount in lost revenues for “$16.8 million in actual program delivery is
unreasonable.” Exhibits at 101. Mr. Rábago further testified that, under
CAC’s four-year-cap proposal, total lost revenues would amount to $14.4
million.
[8] CAC also argued that testimony from a Vectren South witness, Dr. M. Sami
Khawaja (“Dr. Khawaja”), Chief Economist at The Cadmus Group (an energy
efficiency evaluation firm), created a conflict of interest and should be
disregarded because The Cadmus Group had been retained by Vectren South to
perform evaluation services for the past eight years. According to CAC,
Section 10 requires that the EM&V procedures be independent, and that Dr.
Khawaja’s advocacy position “in this proceeding . . . casts doubt on the
integrity of the firm’s work as an independent evaluator.” Id. at 114.
[9] The Commission determined that “the only issue we need to address in this
proceeding [on remand] is the reasonableness of Vectren South’s [Revised Lost
Revenue Proposal].” Appellant’s Appendix Volume 2 at 16. Thus, on
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 9 of 28
December 20, 2017, the Commission issued its twelve-page Order on Remand,
concluding that “Vectren South’s modified lost revenue recovery proposal,
which has a strong relationship with the EM&V process, is reasonable.” Id. at
18. The Order reads in pertinent part:
Vectren South proposed a modified approach to its initial
proposal for lost revenue recovery, which caps lost revenue
recovery associated with its Plan by using the WAML of the Plan
programs and reduces the resulting recovery by an additional
10%. . . . Thus, the proposed LRAM is projected to recover
slightly less than $26 million of lost revenues over the nine-year
WAML of the Plan or, on average, approximately $2.9 million
per year.
*****
CAC argues that a four-year cap on lost revenue recovery is
reasonable because a term greater than four years creates
unreasonable difficulties in tracking the accuracy of lost revenues
[and] the pancaking or cumulative effect of lost revenues over
time on rates[;] and lost revenue policies were created at a time
when the period between rate cases was shorter.
Based on the evidence presented as further discussed below, we
find Vectren South’s modified proposal for lost revenue recovery
is reasonable and approve the Plan in its entirety. It is commonly
understood that the calculation of lost revenues is not an exact
science and there will always be a range of what may be
considered reasonable lost revenue recovery. Vectren South has
sufficiently demonstrated that its WAML proposal is grounded in
the EM&V processes that are required by Section 10 and
universally relied upon in the utility industry to estimate energy
savings and associated lost revenues. The other parties did not
provide us with evidence demonstrating that Vectren South’s
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 10 of 28
proposal is unreasonable. Nor did they provide us with sufficient
facts from which we could determine that a four-year (or less) cap
on lost revenue recovery would allow Vectren South to recover
reasonable lost revenues.
*****
In addition to the use of the nine-year WAML, Vectren South
proposes to recover only 90% of the annual energy savings. CAC
and other parties, in their post-hearing filing, argue that because
EM&V is only conducted once for each Plan year, the initial
determination of energy savings and lost revenue becomes
progressively less reliable and more uncertain in successive years
and therefore should not be relied upon. Further, they argue that
the proposed 10% reduction in energy savings only addresses the
degree of confidence in the threshold EM&V determination, not
the eroding reliability of assumed savings.
EM&V is the most established approach to reasonably estimating
energy savings and lost revenues associated with EE programs.
Vectren South’s approach appears reasonably designed to ensure
it recovers only the lost revenues that EM&V can establish, with
a high degree of confidence, [and that] will result from savings
driven by EE measures. Recognizing that estimates are more
certain in the immediate as opposed to the distant future, Vectren
South’s evaluation process for estimating net energy savings . . .
results in a statistically conservative estimate. While we
recognize that EM&V degrades over time based on accumulating
changes, this degradation is built into the EM&V process. We
further find that the approximate 24% reduction in recovered lost
revenues compared to Petitioner’s initial [revenue recovery]
proposal is intended to strike a reasonable balance in terms of
offsetting the inherent financial harm to a utility caused by EE
sales reductions, while also ensuring the recoveries are fully
supported by conservative EM&V estimates that safeguard the
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 11 of 28
cost and benefit analysis relied upon to determine that the EE
Plan provides short- and long-term benefits to customers.
*****
Rather than providing a reasoned explanation or analysis to
support ending lost revenue recovery after four years[,] regardless
of measure life[,] or evidence related to the financial effects of
such a proposal on Petitioner, CAC instead offers a conclusory
opinion that the magnitude of lost revenues exceeds the program
costs, which makes the proposal unreasonable. CAC provided
no factual basis to support its contention that lost revenues
should not exceed program costs. . . . [C]ost-effective EE
programs should have lower program[] costs with larger energy
savings, which does result in higher lost revenues relative to
program costs.
*****
Section 10(o) similarly recognizes the importance of subjecting
lost revenues to EM&V. Vectren South’s [Revised Lost Revenue
P]roposal recognizes that the EM&V process is not a perfect
science. It also employs limitations on EM&V quantification of
savings (and thus lost revenues) that ensure customers are billed
for lost revenues based on a conservative determination of
achieved savings with the highest level of confidence in the
energy savings attributed to EE measures. Accordingly, we find
Vectren South’s Plan is reasonable and approved.
Id. at 17-19.
[10] Regarding whether testimony from Dr. Khawaja should have been disregarded,
the Commission determined that:
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 12 of 28
Dr. Khawaja’s testimony was largely limited to addressing the
reasonableness of EM&V results over time and how the issues of
uncertainty and persistence are accounted for in the EM&V
process and methodology. While it may have been more prudent
for Petitioner to retain an EM&V witness not associated with
Cadmus, we lack sufficient evidence to find that EM&V
independence has been undermined – particularly given the
request for proposal process for selecting the EM&V entity and
the ongoing participation by members of the [Vectren Oversight
12
Board ] in the review of the EM&V analysis and reports.
Id. at 18.
[11] CAC now appeals the Commission’s Order on Remand. This is the second
appeal related to Vectren South’s Plan for calendar years 2016-2017.
Discussion
Standard of Review
[12] The General Assembly created the Commission primarily as a factfinding body
with the technical expertise to administer the regulatory scheme devised by the
legislature. N. Ind. Pub. Serv. Co. v. U.S. Steel Corp., 907 N.E.2d 1012, 1015 (Ind.
2009). The Commission’s assignment is to insure that public utilities provide
constant, reliable, and efficient service to the citizens of Indiana. Id. “The
Commission can exercise only power conferred upon it by statute.” Id.
“Because the complicated process of ratemaking is a legislative rather than

voting members of the Board.

judicial function, it is more properly left to the experienced and expert opinion
present in the Commission.” Citizens Action Coal. of Ind., Inc. v. N. Ind. Pub. Serv.
Co., 76 N.E.3d 144, 151 (Ind. Ct. App. 2017) (internal quotations omitted).
[13] Indiana Code § 8-1-3-1 (1993) authorizes judicial review of Commission orders
by this Court. The review involves multiple tiers. U.S. Steel, 907 N.E.2d at
1016. “On the first level, it requires a review of whether there is substantial
evidence in light of the whole record 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. (citation and footnote omitted). We neither reweigh evidence
nor assess witness credibility, and we consider only the evidence favorable to
the Commission’s findings. Id. The Commission’s order is not binding if it
lacks substantial evidence supporting the findings of the Commission or is
unreasonable or arbitrary. Id.
[14] “At the second level, the order must contain specific findings on all the factual
determinations material to its ultimate conclusions.” Id. 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. Id. 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. Id. “More specifically, on matters within its
jurisdiction, [the Commission] enjoys wide discretion and its findings and
decision will not be lightly overridden simply because we might reach a
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 14 of 28
different decision on the same evidence.” Citizens Action Coal. of Ind., Inc., 76
N.E.3d at 151 (brackets and internal quotation omitted). “Essentially, so long
as there is any substantial evidence to support the rates as fixed by the
Commission as reasonable, the judicial branch of the government will not
interfere with such legislative functions and has no power or authority to
substitute its personal judgment for what it might think is fair or reasonable in
lieu of [the Commission’s] administrative judgment.” Id. (brackets, emphasis,
and internal quotations omitted).
[15] Findings of fact are important because they help us understand the
Commission’s reasoning and policy judgments and allow for a reasoned and
informed 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. N. Ind. Pub. Serv. Co. v. LaPorte, 791
N.E.2d 271, 278 (Ind. Ct. App. 2003). Further, requiring findings of fact helps
the Commission avoid arbitrary and capricious action. Id.
[16] “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 involved in producing its decision, ruling, or order.” U.S. Steel, 907
N.E.2d at 1016.

I. Whether the Commission’s Order on Remand is Contrary to Law
[17] CAC’s first argument is twofold. It contends that the Commission’s Order on
Remand is contrary to law because the approval of Vectren South’s Revised
Lost Revenue Proposal is unreasonable, and that it is inconsistent with Section
10. We address each argument in turn.
A. Whether the Approval of the Revised Lost Revenue Proposal is
Unreasonable
[18] CAC maintains that the Commission should have reviewed Vectren South’s
overall financial condition when it determined whether the Revised Lost
Revenue Proposal was reasonable and just. The crux of CAC’s argument is
that:
[b]ecause the Commission[, in approving the Revised Lost
Revenue Proposal,] has ignored the requirement that each
utility’s rates must be set on the utility’s overall financial
condition including total revenue and expense, the approval of
Vectren [South]’s lost revenue rate recovery in the [Order on
Remand] is not just and reasonable, and should be declared
unlawful by this Court.
Appellant’s Brief at 28. According to CAC:
[t]he approved lost revenue rate in the [Commission’s Order on
Remand] just guarantees rate recovery based on projected savings
without any consideration for other ratemaking principles. It
also disregards the distinction between a utility who comes in for
regular rate cases, regularly zeroing out lost revenue totals when
resetting rates, versus a utility who does not reset rates but for
once every 10, 15, 20 years, resulting in exorbitant lost revenue
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 16 of 28
rate recovery and millions of dollars in difference in terms of
what the ratepayers is [sic] required to pay.
Id. at 27. CAC also argues that to allow Vectren South to recover the requested
13
amount dissuades Vectren South from filing general rate cases.
[19] CAC further argues that the Revised Lost Revenue Proposal is unreasonable
because it allows Vectren South to recover $25.9 million in lost revenue for EE
programs projected to cost $16.8 million to administer. It states that “lost
revenue rates at 1.54 times greater than the cost to actually run the programs is
far in excess of what is necessary to satisfy a monopoly utility’s shareholders’
legitimate expectations.” Id. at 25-26. CAC claims that “[t]his lost revenue is
outside the zone of reasonableness in light of the legal framework, ratemaking
policy, regulatory history, objective of the required cost-effectiveness in the
statute, and the appropriate degree of reliability in forecasting estimated savings
out beyond a few immediate years.” Id. at 26. CAC contends that “it is
particularly wasteful and results in artificially high prices to award a utility 1.54
times more in revenue than costs to run the energy efficiency programs with no
13
CAC posits that the approval of lost revenues is subject to a “just and reasonable” rates standard under
Indiana Code § 8-1-2-4 (1984), the general rate statute, which provides in relevant part that “[t]he charge
made by any public utility for any service rendered or to be rendered either directly or in connection
therewith shall be reasonable and just, and every unjust or unreasonable charge for such service is prohibited
and declared unlawful.” However, in its Surreply Brief, CAC clarifies that in referencing the statute, it was
not raising a new argument. CAC acknowledges that it should have been more careful with its phrasing, but
that “the point . . . is this: by failing to consider its precedent of capping the time a lost revenue rate
adjustment mechanism may be used due to Indiana’s environment of infrequent rate cases, the Commission
brings the just and reasonable rates requirement from I.C. § 8-1-2-4 and the examination of the utility’s
overall financial condition to the forefront . . . .” Appellant’s Surreply Brief at 6.
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 17 of 28
shown correlation that this extra revenue will equate to more energy efficiency
services or savings.” Id. at 27.
[20] We are not persuaded by CAC’s arguments. The only disputed factor on
remand was Vectren South’s Revised Lost Revenue Proposal. Section 10(j)(8)
provides that, when the Commission makes a determination of the overall
reasonableness of a plan, it must consider the lost revenues and financial
incentives associated with the plan and sought to be recovered or received by
the utility. Section 10(o) provides that if the Commission finds a plan
submitted by a utility to be reasonable then the Commission must allow the
utility to recover or receive reasonable lost revenues. Here, the Commission
considered the lost revenues sought to be recovered and determined that CAC
“provided no factual basis to support its contention that lost revenues should
not exceed program costs.” Appellant’s Appendix Volume 2 at 18.
Furthermore, Section 10 does not require the Commission to consider a utility’s
overall financial condition in determining whether lost revenues sought to be

Commission did not act contrary to law in determining that Vectren South’s
Plan was reasonable.
B. Whether the Approval of the Revised Lost Revenue Proposal is inconsistent
with Section 10
[21] CAC also argues that the Commission’s approval of the Revised Lost Revenue
Proposal is inconsistent with Section 10. It contends that the Commission’s
Order on Remand “misinterprets and misconstrues” that section by
“establishing rates under Section 10 without any reference or consideration of
ratemaking practices and the requirements of Indiana’s Public Service
Commission Act (‘PSCA’).” Appellant’s Brief at 36. CAC specifically argues
that “the most basic error is the Commission’s failure to reconcile its approval
of [the Revised Lost Revenue Proposal] without any reference or application of
ratemaking policies” and the Commission’s failure to “consider ratepayers in
making a determination as to the reasonableness of this rate.” Id.
[22] We observe that the requirement under Section 10 that electricity suppliers file a
three-year EE plan was adopted by our General Assembly in 2015 as a separate
requirement that is in addition to long-standing requirements regarding general
ratemaking. CAC points to no relevant authority indicating that the
Commission was required to consider or apply procedures adopted in
connection with general ratemaking cases when considering a petition filed in
accordance with Section 10. CAC has failed to establish that the Commission’s
approval of Vectren South’s Revised Lost Revenue Proposal is inconsistent
with Section 10. We, therefore, find that the Commission’s approval of the
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 19 of 28
Revised Lost Revenue Proposal was not inconsistent with Section 10 and was
not contrary to law.
II. Whether the Commission’s Order on Remand Impermissibly Deviates from
Precedent
[23] We next address whether the Commission impermissibly deviated from
precedent. CAC maintains that the Commission’s Order on Remand “ignores
available precedent related to the relationship between lost revenues and
general rate cases that articulated principles by which to ascertain the
reasonableness of lost revenue recovery proposals.” Appellant’s Brief at 29.
According to CAC, “the relationship between rate cases and lost revenues, as
articulated in the Commission’s [First] Order and other available precedent,
was a material issue raised and put in dispute by the parties before the
Commission in this remand proceeding, but it went unaddressed.” Id.
[24] In support of its argument, CAC cites to four Commission decisions. See In re
Ind. Power & Light Co., Cause No. 43911, 2010 WL 4499412, at *9 (November
4, 2010) (denied lost revenue recovery “in absence of a base rate case to ensure
that class specific investment and investment recovery is properly aligned”); In
re N. Ind. Pub. Serv. Co., Cause No. 43912, 2011 WL 3346770, at *22 (July 27,
2011) (denied request to recover lost margins but remained “willing to consider
a request for lost margins, provided NIPSCO can demonstrate the revenue
margin rates are reasonably reflective of today’s operations”); In re N. Ind. Pub.
Serv. Co., Cause No. 44634, 2015 WL 9605053, at *30, 31 (December 30, 2015)
(Commission acknowledged that it had “previously approved lost revenues over
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 20 of 28
a measure’s life or until a utility’s next base rate case, whichever is shorter,” but
due to “concerns with pancaking and the increased length of time between base
rate cases for utilities in Indiana,” ultimately found NIPSCO’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 implemented pursuant to a final order in
NIPSCO’s next base rate case, whichever occurs earlier.”); In re Duke Energy
Ind., Inc., Cause No. 43955, 2016 WL 1118794 (March 16, 2016) (denied
approval of Duke’s EE plan, finding, in part, that recovery of lost revenues
should be limited to four-year term). However, nothing in our review of these
decisions leads us to the conclusion that reversal is required in this case.
[25] By its own acknowledgement, the Commission has previously approved the
recovery of lost revenues over a measure’s life or until the utility’s next base rate
case, whichever is shorter. The Commission has also previously approved a
four-year cap on a utility’s lost revenue recovery. An agency may change its
course and is not forever bound by prior policy or precedent as long as it
explains its reasons for doing so. See Ind. Bell Tel. Co. v. Ind. Util. Reg. Comm’n,
810 N.E.2d 1179, 1186 (Ind. Ct. App. 2004), trans. denied. In its Order on
Remand, the Commission found Vectren South’s Plan to be reasonable in its
entirety, found Vectren South’s Revised Lost Revenue Proposal to be
reasonable, and explained its reasons for doing so. The Commission did not
impermissibly deviate from precedent.

III. Whether Substantial Evidence Supports the Commission’s
Order on Remand
[26] CAC’s last argument is that the Commission’s Order on Remand “lacks a
reasonably sound basis of evidentiary support.” Appellant’s Brief at 33.
Specifically, CAC maintains that 1) the Commission failed to consider the
“relationship of the lost revenue rate with the resetting of rates in general rate
cases”; 2) the Order on Remand failed to “mention or weigh any of the critical
cross-examination that was conducted by the other consumer parties”; and 3)
the Order on Remand failed to mention certain evidence of record from the
underlying proceeding, namely, a white paper from the American Council for
an Energy-Efficient Economy. Id. at 33-34, 35.
[27] Our inquiry here is limited to whether there is substantial evidence supporting
the Commission’s Order on Remand. U.S. Steel, 907 N.E.2d at 1016. We
neither reweigh evidence nor assess witness credibility, and we consider only
the evidence favorable to the Commission’s findings. Id. Here, the record
reveals the following substantial evidence supporting the Commission’s Order
on Remand and its ultimate approval of Vectren South’s Revised Lost Revenue
Proposal.
[28] Testifying for Vectren South, Ms. Harris explained in detail how Vectren South
calculates lost revenues. She testified that it is reasonable to collect lost
revenues for the Plan for the life of the measure because “utility revenues
continue to be reduced over time by energy efficiency measures or programs
each year for the life of the measure”; thus,“[i]t is reasonable to match the
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 22 of 28
ability to recover lost revenues for the programs over the same life which is used
to determine a program’s cost effectiveness.” Exhibits at 22. She added that
Vectren South’s EE programs “undergo rigorous, independent, third-party
[EM&V] process to determine the actual program savings which are used to
determine cost effectiveness of programs and also serve as the basis for the lost
revenue calculation.” Id. She explained how the EM&V results would be
applied in the calculation of the lost revenues, why a four-year cap on the
recovery of lost revenues was not appropriate and would cause financial harm
to Vectren South, and how and why Vectren South’s Revised Lost Revenue
Proposal, based on “(1) the weighted average measure life (‘WAML’) of the
[Plan] period[,] and (2) a 10% reduction in annual savings,” provides “even
greater assurance customers are paying only for lost revenues that result from
EE measures.” Id. at 24. She further explained that under the Revised Lost
Revenue Proposal, “Vectren South would recover the reasonable amount of lost
revenues associated with the weighted average measure life of its EE programs
or the measure life, whichever is less,” and that the WAML of the portfolio
would be re-evaluated and adjusted with each EE filing.” Id. On rebuttal, she
testified to “two key factors” associated with Vectren South’s Revised Lost
Revenue Proposal “that make it superior to the approaches recommended by
the OUCC and CAC and they are: (1) lost revenue recovery remains connected
to measure life; and (2) lost revenue recovery remains connected to EM&V,
which has been relied upon for decades in the determination of lost revenues.”
Id. at 45.
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 23 of 28
[29] Dr. Khawaja, who has conducted impact evaluation studies for energy
efficiency programs for nearly thirty-five years and is an expert in evaluation
methods, also testified for Vectren South and described the EM&V process
utilized for it. He explained that confidence and precision energy program
evaluation is “typically based on estimating energy impacts using a
representative sample of program participants to determine how measures are
installed and used.” Id. at 54. He stated that the results of these efforts are then
used to estimate savings for the program and that, for Vectren South, “program
evaluations are in line with the industry standard of obtaining estimates with a
confidence level of 90% with a relative precision of ±10%.” Id. He testified
that it is appropriate to recover lost revenues for the life of a measure and to cap
lost revenue based upon the WAML of a plan; and, he expressed his concerns
regarding placing a four-year cap on lost revenue recovery. In summary, he
stated:
In my view, Vectren South’s use of evaluation results, combined
with the [effective useful lives (“EUL”)] of program measures, is
a conservative basis for the calculation of lost revenues.
First, the EUL values used are conservative (Vectren South
estimate of weighted average life is 9 (rounded from 8.5) years
while the same estimate based on industry values is 9.5 years).
Second, Vectren South’s evaluation process for estimating net
energy savings utilizes at minimum a 90% confidence interval
(industry accepted standard). Vectren South supports a 10%
degradation of annual savings within its lost revenue calculation.
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 24 of 28
This reflects using the lower end of the confidence interval which
is also statistically conservative. . . .
Finally, it is extremely likely that lost revenues are far in excess
of those claimed due to the significant amount of market effects
caused by utility DSM programs.
Id. at 58.
[30] Scott E. Albertson (“Mr. Albertson”), Vice President of Regulatory Affairs and
Gas Supply for Vectren Utilities Holdings, Inc., also testified on behalf of
Vectren South and addressed concerns regarding the frequency of rate cases and
the concept of pancaking lost revenues. When asked if the frequency of a
utility’s rate cases contribute to the magnitude of lost revenues, he replied as
follows:
Yes and no. While the costs recovered via an LRAM (i.e.[,] a
lost revenue adjustment mechanism) would be lessened if rate
cases were filed more frequently, the revenues lost as a result of
EE are included in base rates each time the utility files a rate
case. In either case, the appropriate level of fixed costs will be
included in customers’ bills. Customer usage at the time of a rate
case reflects the usage reductions resulting from EE, thus
increasing unit rates as needed to recoup fixed costs. So[,]
whether via an LRAM or new base rates, the utility should
recover the revenues needed to recover the approved level of
fixed costs. An LRAM cap is merely a temporary limit on
recovery which may force utilities into rate cases sooner and
more frequently than would have otherwise been the case had the
period of lost revenue recovery matched the lives of EE measures
implemented by customers. And, as noted by the Court of
Appeals, rate cases are “expensive, time consuming, and
sometimes result in large, sudden rate hikes for customers.”
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 25 of 28
Thus, capping lost revenue recovery to force utilities to file a rate
case is not good public policy.
Id. at 68. He further testified that if a four-year cap on lost revenue recovery
were implemented, a utility would be incented to offer only programs that have
lives of four years or less, and that “[i]t simply would not make sense to embed
such a perverse incentive into the EE Program framework.” Id. at 69. On
rebuttal, Mr. Albertson testified that Vectren South’s Revised Lost Revenue
Proposal sets a reasonable limit on the recovery of lost revenues. He refuted
claims by Mr. Rábago that, under the Revised Lost Revenue Proposal, Vectren
South would over-recover lost revenues. He further testified that Mr. Rábago
“has provided no specific evidence to support that a [four-year] cap would
allow Vectren South reasonable lost revenue recovery.” Id. at 76.
[31] The Commission reviewed the evidence and determined that Vectren South’s
Revised Lost Revenue Proposal was reasonable, and that Vectren South’s Plan
was reasonable in its entirety. The Commission found that “the calculation of
lost revenues is not an exact science”; that “there will always be a range of what
may be considered reasonable lost revenue recovery”; and that “Vectren South .
. . sufficiently demonstrated that its [Revised Lost Revenue Proposal] is
grounded in the EM&V processes that are required by Section 10 and
universally relied upon in the utility industry to estimate energy savings and
associated lost revenues.” Appellant’s Appendix Volume 2 at 17. The
Commission was unpersuaded by CAC’s arguments regarding a four-year cap
on lost revenue recovery and further found that CAC did not provide it with
Court of Appeals of Indiana | Memorandum Decision 18A-EX-95 | March 11, 2019 Page 26 of 28
evidence “demonstrating that Vectren South’s proposal is unreasonable” or
with “sufficient facts from which [it] could determine that a four-year (or less)
cap on lost revenue would allow Vectren South to recover reasonable lost
revenues.” Id. The Commission also found that “[r]ather than providing a
reasoned explanation or analysis to support ending lost revenue recovery after
four years regardless of measure life or evidence related to the financial effects
of such a proposal on [Vectren South], CAC instead offer[ed] a conclusory
opinion that the magnitude of lost revenues exceeds the program costs, which
makes the proposal unreasonable” and “provided no factual basis to support its
contention that lost revenues should not exceed program costs.” Id. at 18. It
further found that “[i]t is inherent to EM&V that validated energy savings will
create lost revenues”, and that “[c]onsequently, cost-effective EE programs
should have lower programs [sic] costs with larger energy savings, which does
result in higher lost revenues relative to program costs.” Id.
[32] Based upon our review of the record, we conclude that there is substantial
evidence to support the Commission’s determination that Vectren South’s
Revised Lost Revenue Proposal is reasonable and that the Plan is reasonable
and should be approved in its entirety. CAC’s arguments to the contrary
amount to an invitation to reweigh the evidence, we do not reweigh evidence or
reassess witness credibility on appeal. See U.S. Steel, 907 N.E.2d at 1016.
[33] For the foregoing reasons, the Commission’s Order on Remand is affirmed.
[34] Affirmed.
