Re:
Docket No. 07-085-TF
In the Matter of the Application of Entergy Arkansas, Inc.
For Approval of Energy Efficiency Programs and Energy
Efficiency Cost Rate Rider
Dear Ms. Rhude:
Please find attached for filing with the Arkansas Public Service Commission
(APSC), Entergy Arkansas, Inc.’s (EAI or the Company) request for approval of
the revised Rate Schedule No. 40, Energy Efficiency Cost Rate Rider (Rider
EECR) Attachments A, B, and C reflecting the revised Rider EECR Rates and
Rate Calculation.
EAI has calculated its 2013 Rider EECR Rate using the estimated 2013 program
costs as included in EAI’s Energy Efficiency Three-Year Plan approved by the
Commission in Order No. 39 of the above referenced docket and adjusted as
described in the Direct Testimony of Jeremy E. Champlin submitted in support of
this filing.
As explained by Mr. Champlin, EAI’s budget adjustments are within the APSC’s
budget flexibility guidelines, with one exception. EAI has proposed to remove 17
percent of the original approved budget from the Energy Star New Homes
Program and add the amount to the Multi-family Home Program. In accordance
with the Order No. 39 budget flexibility directives, EAI requests Commission
approval to remove more than 10 percent of the budget for the Energy Star New
Homes Program.
Additionally, Mr. Champlin describes the calculation of the Lost Contribution to
Fixed Costs (LCFC) to be recovered through Rider EECR in accordance with the
Commission’s Order No. 14 issued December 10, 2010 in Docket No. 08-137-U

4/8/2013 11:08:44 AM: Recvd 4/8/2013 11:02:39 AM: Docket 07-085-TF-Doc. 380
and the calculation of EAI’s incentive based on EAI’s 2012 program results in
accordance with Order No. 15 issued December 10 in Docket No. 08-137-U.
Additional details regarding the 2012 actual program costs and the calculation of
LCFC and incentives is provided in the Company’s 2012 Energy Efficiency
Program Portfolio Annual Report filed concurrently in this docket.
Also submitted is the Direct Testimony of Charles E. DeGeorge, which describes
the avoided energy and capacity costs used in the economic evaluation of EAI’s
energy efficiency programs.
Finally, EAI also submits the Direct Testimony of Margaret L. McCloskey, which
supports the calculation of the Rider EECR rates. The revised Attachments A, B,
and C are attached to Ms. McCloskey’s direct testimony as EAI Exhibit MLM-3.
The monthly bill of a typical residential customer using 1,000 kWh per month
would increase by $1.44 or 68.2 percent if the revised Rider EECR rates are
approved.
EAI respectfully requests Commission approval of the revised Rider EECR,
Attachments A, B, and C and approval of the request to reduce the budget for the
Energy Star New Homes Program by more than 10 percent. The terms of Rider
EECR specify an effective date of the first billing cycle of June for redetermined
rates.
If the Rider EECR rates are not resolved in time for a June
implementation, EAI requests APSC approval for an effective date of the first
billing cycle of the month following approval of the Rider EECR. If you have any
questions or need anything additional concerning this filing, please call me at
(501) 377-4457 or Susan Davidson at (501) 377-5720.
Work papers supporting the revised calculation of the tariff rates will be provided

BENEFIT-COST TEST RESULTS
6
Q.
WHAT WERE THE PROJECTED BENEFIT-COST ANALYSIS RESULTS
FOR THE 2013 PROGRAM YEAR?
7
8
A.
The 2013 program year with the updated budgets described above,
results in a projected portfolio net benefit of $24,758,065 and a benefit-
9
cost ratio of 1.27 based upon Total Resource Cost (“TRC”) Test.
10
11
12
Q
WHAT WERE THE BENEFIT-COST ANALYSIS RESULTS FOR 2012?
13
A.
EAI performed a benefit-cost test on the evaluated savings for the 2012
14
program year. The TRC Test remained positive with a TRC net present
15
value of $9,975,512 and a TRC ratio of 1.23. Of the 15 programs, 9
16
programs achieved a TRC ratio above 1.0 with 6 programs falling below.
17
As discussed last year, the primary concern for these benefit-cost analysis
18
results are due to low avoided cost. Further, the TRC Test results for
19
three programs, Energy Star New Homes, Residential Benchmarking and
20
Agricultural Energy Solutions, were below due to market conditions and/or
21
a late start in the market due to the length of time required to conduct
22
thorough due diligence prior to completing contracts with third-party
23
implementers to ensure that customer information is protected. The cost

V.
CALCULATION OF LCFC
14
Q.
HOW DID EAI CALCULATE THE LCFC FOR EACH PROGRAM YEAR?
15
A.
LCFC is a cumulative amount based on the LCFC for individual program
16
years, which are accumulated until the Company implements new base
17
rates as a result of a general rate case decision. Upon the implementation
18
of new base rates the cumulative portion of the LCFC calculation is reset.
19
With EAI’s base rate filing made March 1, 2013 (Docket No. 13-028-U),
20
this effectively means that, from a cumulative perspective, EAI’s LCFC
21
calculation will reset.
22
Each year, the LCFC for the current program year is based on the
23
projected energy savings targets approved in the Company’s energy

are then multiplied by the average rate class annualized Lost Contribution
9
Rate (“Average LCR”). The Average LCR is the base rate revenues less
10
customer charge revenues calculated on a dollar per kWh basis, using the
11
Company’s most recently approved base rates.
12
The current program year LCFC also includes the prior years’ full
13
year LCFC amounts for each program year accumulated since base rates
14
were last set. The prior years’ LCFC amounts are calculated based on the
15
actual evaluated energy savings achieved, on a measure by measure
16
basis, multiplied by the seasonal rate schedule base rates less customer
17
charges (“Seasonal LCR”). The prior years’ measures are reviewed and
18
adjusted if the efficiency measures installed have reached the end of their
19
lives.
20
Also, each year, the prior year’s LCFC amount is trued-up. The
21
projected portion of the prior year’s LCFC is recalculated based on actual

The First Year Monthly Curve Ratio is a ratio developed by ICF International specifically for EAI

will be adjusted during the annual true-up process.

Q.
WHAT IS THE 2013 LCFC?
5
A.
As I explained above, the 2013 LCFC includes the projected 2013 LCFC
6
and the full year trued-up LCFC for 2011 and 2012. The 2013 first year
7
estimated LCFC is $2,530,087. The 2011 full year LCFC is $1,917,064.

Q.
WHAT IS THE 2012 TRUED-UP LCFC ?
12
A.
As I explained above, the 2012 LCFC includes the true-up of the projected
13
2012 program year LCFC and the full year trued-up LCFC for 2011. The
14
2012 prorated trued-up LCFC is $1,410,888. The 2011 full year LCFC is
15
$1,917,064. The cumulative total LCFC for 2012 is $3,327,951.
16
The 2012 true-up prorated LCFC is less than the projected 2012
17
prorated amount because some programs were implemented later than
18
planned due to the length of time required to conduct thorough due
19
diligence prior to completing contracts with third-party implementers to

RIDER EECR.
14
A.
In Order No. 15 of Docket No. 08-137-U, the APSC provided directives as
15
to both the qualification and calculation of incentives. Under that order,
16
the program year evaluated savings results must meet at least 80 percent
17
of the goal established by the Commission for a utility to qualify for an
18
incentive. The calculation includes a shared savings amount based upon
19
10 percent of the portfolio Net Present Value of the TRC Test, but not to
20
exceed 5 percent of portfolio budget if evaluated goal achievement is at
21
least 80 percent up to 100 percent and not to exceed 7 percent of portfolio
22
budget for evaluated goal achievement at 100 percent up to 110 percent.

EAI’s target for 2012 was 96,694 MWh of energy reductions.7 EAI’s
2
evaluated energy savings for 2012 is 107,627 MWh before line loss
3
adjustments.8 This result of 111 percent of target qualifies EAI to obtain
4
incentives. Because EAI achieved over 100 percent target, the Company
5
qualifies at the program cost cap of 7 percent. The 7 percent cap is
6
applied to the final 2012 program budget of $39,609,138 resulting in a
7
maximum possible incentive of $2,772,640. The program portfolio Net
8
Benefits based on Total Resource Cost analysis for 2012 was $9,975,512
9
and the shared savings of 10 percent is $997,551. Because the shared
10
saving amount is the less than the 7 percent cost cap, EAI’s incentive
11
amount is $997,551. EAI included this incentive amount in the total costs
12
to be included in the EECR recovery amount.
13
14
Q.
DOES THIS CONCLUDE YOUR DIRECT TESTIMONY?
15
A.
Yes, it does.
7
EAI’s energy savings target for 2012 of 105,413 MWh as reported in EAI’s Three-Year Plan is
reduced to reflect the impact of the Self-Direct customer’s exempted usage as provided by the
APSC’s Rules for Conservation and Energy Efficiency Programs, Section 11, subsection O.
8
EAI’s evaluated energy savings results reflect the application of NTG adjustments as directed
by the Commission. See Docket No. 07-152-U, Order No. 7; Docket No. 08-137-U, Order No. 16;

A.
ITS 2013
ENERGY EFFICIENCY
EAI proposes to allocate the costs of its 2013 Energy Efficiency Programs
6
and the LCFC using the production demand allocation factor (“PDAF”)
7
approved in the Company’s most recent rate case adjusted to remove the
8
customer accounts that are exempt from the Rider EECR charge for the

Q.
WAS
THE
PDAF
SELECTED
AS
THE
ALLOCATION
METHODOLOGY FOR RIDER EECR?
13
14
WHY
A.
EAI’s Energy Efficiency Programs and the related LCFC provide
15
significant benefits, including the reduction in demand-related production
16
costs. Production costs are allocated based on either demand or energy,
17
and because these costs are demand-related, it is appropriate to use the
18
PDAF to allocate these costs.

CAPITAL COSTS?
2
3
4/8/2013 11:02:39 AM: Docket 07-085-TF-Doc. 380
A.
Yes.
In EAI Exhibit MLM-3, EAI has included a revenue requirement
4
calculation associated with incremental capital costs incurred in
5
connection with EAI’s Agricultural Irrigation Load Control (“AILC”)
6
Program1 and included that revenue requirement within the total revenue
7
requirement for EAI’s energy efficiency programs to be recovered through
8
the redetermined Rider EECR rate for 2013.
9
Consistent with the methodology used in prior years’ Rider EECR
10
updates, the AILC revenue requirement is the sum of the return on rate
11
base calculated by applying the before-tax rate-of-return on rate base as
12
approved in Docket No. 09-084-U to the average rate base and the
13

EAI’s Irrigation Load Control Program budgets for capital and expenses for the program years
2011 and 2012. In Order No. 39, issued in Docket No. 07-085-TF on June 30, 2011, the APSC
approved EAI’s AILC Program and budgets for program years 2011-2013 which incorporated the
2011 and 2012 AILC budgets approved in Docket No. 08-072-TF. In addition, the APSC
approved the transfer of the AILC Program to Docket No. 07-085-TF and the closing of Docket

A.
EAI requested estimates of avoided costs of energy and capacity for 2012

WHAT ANALYSES WERE PERFORMED TO ESTIMATE THE AVOIDED
A.
The analyses were divided into two time frames to estimate the avoided
11
energy cost. The first time frame, 2012 and 2013, represents the period
12
when EAI is still a participant in the Entergy System Agreement and is not
13
yet a participant in a Regional Transmission Organization (“RTO”). The
14
second time frame, 2014 and beyond, represents the period when EAI no
15
longer participates in the Entergy System Agreement and is assumed to
16
be a participant in the Midwest Independent Transmission System
17
Operator, Inc. (“MISO”) RTO.

WHAT ANALYSIS WAS USED TO ESTIMATE THE AVOIDED ENERGY
A.
The AURORAxmp Electric Market Model (“AURORA”) model was used to
14
simulate market operations and produce a long-term forecast of the
15
Locational Marginal Price (“LMP”) for the EAI commercial pricing zone as
16
part of operating in the MISO Day 2 Market.4 AURORA estimates price
17
and dispatch using hourly demands and individual resource-operating
18
characteristics in a transmission-constrained, chronological dispatch
19
algorithm.
4
Day 2 Markets are centralized region-wide markets operated by RTOs that include day ahead
unit commitments, a real time balancing market, and an integrated ancillary services market. In a
Day 2 Market, generators are required to schedule or bid into the market, locational marginal
prices are used to price the use of the transmission grid, congestion charges replace “first come,
first served” transmission service, and financial transmission rights are used to hedge congestion.
The “Day 2” label arose because these are things that RTOs began to implement after they
initially began to operate, or in Day 2 of their creation.

HOW ARE LMPs USED TO DEVELOP ESTIMATES OF AVOIDED
A.
The Aurora model estimates the hourly LMP for each commercial pricing
15
zone of the MISO South footprint. EAI is divided into two load zones
16
representing EAI North Arkansas and EAI Central. A composite LMP for
17
the EAI load zones is determined by taking the load weighted share of the
18
EAI North Arkansas hourly LMP and the EAI Central hourly LMP. The
19
resulting EAI zone LMP is representative of the avoided cost of energy
20
available to EAI each hour based on participation in the MISO Day 2

Market.

4/8/2013 11:02:39 AM: Docket 07-085-TF-Doc. 380
A.
For both time periods, 2012 – 2013 and 2014 - 2035, once the hourly
4
avoided energy cost is determined, an avoided energy cost by time period
5
for each year is calculated by averaging all of the hourly prices within each
6
time period. The results of these analyses are the avoided energy cost
7
estimates, which are provided in highly sensitive EAI Exhibit CED-2.

Q.
ESTIMATE?

11
WHAT IS THE BASIS FOR THE AVOIDED CAPACITY COST
A.
The avoided capacity cost is based on the installed cost of a new
12
combustion turbine (“CT”), which is assumed to be the lowest cost long-
13
term alternative for new capacity that is under the control of EAI. SPO
14
estimated the installed cost of a CT based on the Technology Assessment
15
Guide, which is licensed from the Electric Power Research Institute. To
16
adjust the CT cost for commencing commercial operations in future years,
17
SPO used the CT Capital Cost Real Escalation Rate from IHS CERA
18
Capital Cost Analysis Forum – Power, “Power Capital Cost Index
19
Projection – North America” November 2012 and SPO’s macroeconomic
20
forecast of Gross Domestic Product. Using this approach, the installed
21
cost of a CT is determined for each year of the period 2012 – 2035 and an
22
annual levelized CT revenue requirement is determined by applying a
23
levelized fixed charge rate that is calculated for a CT.

Q.
WHAT OTHER ADJUSTMENTS TO THE ANNUAL LEVELIZED CT
3
COST ARE INCLUDED FOR PURPOSES OF ASSESSING ENERGY
4
EFFICIENCY PROGRAMS?
5
A.
In addition to the installed cost of a CT, the reduction of demand through
6
energy efficiency programs may also potentially avoid transmission and
7
distribution line losses and capacity needed to meet reliability reserve
8
margins.
9
installed CT cost was grossed up by a line loss percentage determined for
10
residential, commercial, industrial, and total retail customer classes.
11
Similarly, to adjust for capacity needed to meet reliability reserve margins,
12
the installed CT cost was grossed up by the reserve margin assumed to
13
be needed by time period. For 2012 – 2013, the reserve margin is 16.85
14
percent based on EAI’s participation in the System Agreement, which is
15
the reserve margin target established for the Entergy Electric System.
16
Beginning with 2014, assuming participation in the MISO RTO, the
17
reserve margin is 12 percent based on historical reserve margin
18
requirements determined by MISO. The result of these adjustments is to
19
increase the installed CT cost by an amount needed to offset the cost of
20
line losses and reliability reserve margins.
To adjust for transmission and distribution line losses, the

ARE OTHER COSTS POTENTIALLY AVOIDED BY REDUCTION IN

DEMAND THROUGH ENERGY EFFICIENCY PROGRAMS THAT ARE
3
REFLECTED IN THE AVOIDED CAPACITY COST ESTIMATE?
4
A.
Yes. In addition to the installed CT cost grossed up for line losses and
5
reserve margin requirements, transmission and distribution investment
6
may be avoided. An estimate of avoided transmission and distribution
7
investment was developed by Utility Operations based on the average
8
cost of actual expenditures over the prior five years, expressed as a
9
levelized annual revenue requirement in terms of $/kW-yr. Therefore, the
10
avoided capacity cost is estimated based on the installed CT cost grossed
11
up for line losses and reserve margin requirements plus an estimate of
12
avoided transmission and distribution investment. The results of these

analyses are the avoided levelized capacity cost estimates, which are
