Please state your name and business address. A. My name is Lovita Griffin and my business address is Arkansas Public Service Commission (Commission), 1000 Center Street, Little Rock, Arkansas, 72201. Q. Are you the same Lovita Griffin who filed Suspension Testimony in this docket on April 2, 2015, on behalf of the General Staff (Staff) of the Commission? A. Yes, I am. II. PURPOSE OF TESTIMONY Q. What is the purpose of your testimony? A. The purpose of my testimony is to make a recommendation regarding the annual redetermination of the Energy Efficiency Cost Recovery (EECR) Rate filed by CenterPoint Energy Arkansas (CEA or Company) on March 31, 2015. Additionally, I will address the Energy Efficiency Program Portfolio Annual Report filed by CEA on March 31, 2015. III. ENERGY EFFICIENCY COST RECOVERY RATE Q. Why did CEA file the annual redetermination of the EECR Rate? A. Pursuant to Section 5.3 of its tariff, CEA filed its 2015 Attachment A in support of its annual redetermination of the EECR Rate to be applied to customers bills rendered on and after the first billing cycle of June 2015. The filing was made in accordance with provisions of Section 7 of the -2-2

Q. What is the Company allowed to collect through the EECR? A. Rule 7(A) of the C&EE Rules states that cost recovery shall be limited to the incremental costs of providing conservation and energy efficiency (EE) programs that are not already included in the current rates of the utility, and may include direct program costs, Lost Contributions to Fixed Costs (LCFC), and utility EE incentives. Q. What steps did you take in reviewing the redetermination of the 2015 EECR Rate (2015 EECR Rate) calculated in Attachment A? A. I reviewed all components used in the development of the 2015 EECR Rate. There are four components used in developing the Program Year (PY) 2015 Recoverable Cost; each component is listed below: a) The PY 2015 EE Portfolio Budget; b) The PY 2015 Projected LCFC; c) The PY 2014 Utility Performance Incentive (Incentive); and d) The true-up of the PY 2014 Recoverable Cost. Table 1 summarizes the four components and the resulting Recoverable Cost for 2015. The results from PY 2012 through PY 2015 are included in Table 1. I will address each of the four components in turn. 21-3- 3

Was the PY 2015 Portfolio Budget approved by the Commission? A. Yes. CEA used the PY 2015 Portfolio Budget of $7,272,764 approved by the Commission in Order No. 73, dated October 28, 2014 in this docket and Order No. 15 in Docket No. 13-002-U, which approved the existing PY 2014 budgets for use in PY 2015. PY 2015 Projected LCFC Q. What is LCFC? A. LCFC refers to the reduction in potential utility sales revenue resulting from decreased energy volumes due to EE measures implemented under utility-funded EE programs. The contemporaneous recovery of LCFC that results from EE programs was authorized by Order No. 14 in Docket No. 08-137-U (LCFC Order). LCFC is a cumulative savings based on measures installed in the current PY and prior PYs. The cumulative savings from the measures installed in a prior PY will continue until the expected life of the measure expires or until the Company implements new base rates through a general rate case, at which time the cumulative portion resets to zero. -4-4

CENTERPOINT ENERGY ARKANSAS DOCKET NO. 07-081-TF DIRECT TESTIMONY OF LOVITA GRIFFIN 1 2 Q. Please describe the PY 2015 Projected LCFC component. A. CEA s current base rates were implemented 2007 pursuant to a general 3 rate application. 1 Therefore, CEA s PY 2015 Projected LCFC consists of 4 5 6 7 8 9 10 11 12 13 14 15 16 17 five years of cumulative savings as follows: 1) The full year impact of the annualized net evaluated energy savings for measures installed in PY 2011; 2) The full year impact of the annualized net evaluated energy savings for measures installed in PY 2012; 3) The full year impact of the annualized net evaluated energy savings for measures installed in PY 2013; 4) The full year impact of the annualized net evaluated energy savings for measures installed in PY 2014; and 5) The estimated partial year impact of the expected net energy savings for measures that will be installed in PY 2015. The components of the PY Projected 2015 LCFC are summarized in Table 2. Table 2 Prior to 2014 Full Year Evaluated Savings PY 2015 Projected LCFC 2014 Full Year Evaluated Savings 2015 Estimated Partial Year Impact Total Projected LCFC (a) (b) (c) (d)=(a)+(b)+(c) $632,567 $193,588 $269,568 $1,095,723 1 Order No. 6, Docket 06-161-U. -5-5

CENTERPOINT ENERGY ARKANSAS DOCKET NO. 07-081-TF DIRECT TESTIMONY OF LOVITA GRIFFIN 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Q. Please explain in more detail the three components of the PY 2015 Projected LCFC shown in Table 2. A. The first component (a) is the annualized net evaluated energy savings attributed to measures installed in PY 2011, PY 2012, and PY 2013 that will realize a cumulative full year savings 4,552,325 Therms in PY 2015. This energy savings results in an LCFC of $632,567 in PY 2015. The second component (b) is the annualized net evaluated energy savings attributed to measures installed in PY 2014 that will realize a full year savings of 1,634,775 Therms in PY 2015. This energy savings results in an LCFC of $193,588 in PY 2015. The third and final component (c) is the estimated non-annualized net energy savings attributed to measures that will be installed in PY 2015, including the true-up of the projected PY 2014 LCFC. CEA has estimated that the 2015 measures will have a partial year savings of 1,550,974 Therms in PY 2015, with an estimated energy savings resulting in an LCFC of $275,512 in PY 2015. However, in PY 2014 CEA over estimated its PY 2014 LCFC by $5,944. To account for this CEA has reduced its PY 2015 LCFC by 244,105 Therms, which results in a reduction in LCFC of $5,944. This adjustment results in a total estimated PY 2015 partial impact savings of 1,306,869 Therms, with an estimated energy savings resulting in an LCFC of $269,568. -6-6

CENTERPOINT ENERGY ARKANSAS DOCKET NO. 07-081-TF DIRECT TESTIMONY OF LOVITA GRIFFIN 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 These three components result in a cumulative energy savings of 7,493,969 Therms and a cumulative LCFC of $1,095,723 in PY 2015, reflected as Table 2, column (d). Q. Did CEA change the methodology used to calculate LCFC for PY 2015? A. Yes. CEA previously operated under its Billing Determinant Adjustment Rider (BDA) which modified its rates to reflect reduction in sales volumes. Since CEA accounted for those lost revenues related to EE through its BDA, it did not include prior PY cumulative savings in its projected LCFC calculations. In this filing, CEA has proposed to collect its cumulative LCFC through the EECR Rate. As a result, and consistent with the LCFC Order, CEA will adjust its BDA to prevent double-counting of any sales reductions already included in the LCFC recovery through the EECR. The change in the LCFC methodology is supported by Company witness Thomas D. Stevens in his Direct Testimony, starting on page 6 at line 7. Q. Do the methodology and calculations used by CEA to develop its PY 2015 Projected LCFC appear to be reasonable? A. Yes. My review of the Company s LCFC calculations revealed no mathematical errors. I reviewed the Company s Lost Contribution Rates (LCR) and the energy savings for estimated PY 2015. The LCR is consistent with CEA s currently approved LCR and the savings are consistent with the PY 2015 EE Program Filings. The methodologies utilized by the Company for its PY 2011 through PY 2014 evaluated LCFC -7-7

CENTERPOINT ENERGY ARKANSAS DOCKET NO. 07-081-TF DIRECT TESTIMONY OF LOVITA GRIFFIN 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 and its estimated PY 2015 LCFC calculations appear to be reasonable. Therefore, I conclude that the PY 2015 Projected LCFC as calculated by CEA is materially accurate. CEA has requested to recover PY 2015 Projected LCFC, in the amount of $1,095,723, which is 15% of its PY 2015 Portfolio Budget. Q. Did the Company true-up the PY 2014 LCFC? A. Yes. As I discussed above, the true-up for CEA s PY 2014 LCFC is reflected in the PY 2015 Projected LCFC of $1,095,723, as shown in Table 2, Column (d). Q. Do the methodology and calculations used by CEA to develop its PY 2014 LCFC true-up appear to be reasonable? A. Yes. CEA relied on after-the-fact, net energy savings, as determined by its independent Evaluation, Measurement and Verification (EM&V) contractor, ADM Associates, Inc.. The measures installed in PY 2014 were adjusted to account for the timing of the installation and heating and cooling degree days as appropriate. This is consistent with the LCFC Order. Therefore, I conclude that the true-up of the PY 2014 LCFC, as calculated by CEA, is materially accurate. PY 2014 Performance Incentive Q. Please describe the Incentive component. A. The Commission approved an Incentive related to EE savings achievement in Order No. 15 in Docket No. 08-137-U. The approved incentive mechanism awards the utility a shared savings of 10% of the -8-8

CENTERPOINT ENERGY ARKANSAS DOCKET NO. 07-081-TF DIRECT TESTIMONY OF LOVITA GRIFFIN 1 2 3 4 5 6 7 8 9 10 11 12 13 portfolio s net benefits for achievement above 80% of the goal. The Commission established a cap of 5% of portfolio budgets for achievement between 80% and 100% of the goal, and a cap of 7% for achievement above 100%. The Commission established goal for PY 2014 for gas utilities was 0.40% of the utility s PY 2010 annual energy sales. Q. Is CEA requesting recovery of an Incentive for PY 2014 results? A. Yes. CEA met the Commission s target in PY 2014 and is eligible for recovery of an Incentive. As shown in Table 3, CEA s savings goal was 2,268,882 Therms and CEA achieved savings of 2,743,851 Therms, which is 121% of the PY 2014 savings goal. CEA is therefore eligible to recover 7% of its Portfolio Budget or 10% of the 2014 Portfolio Net Benefits, whichever is smaller. CEA s performance Incentive for the PY 2014 is $509,094, which is $779,779 less than 10% of the net benefits. 14 Table 3 DERIVATION OF 2014 UTILITY PERFORMANCE INCENTIVE Net Savings 2014 Incentive Calculations 2014 2010 Volume (Therms) 567,220,496 10% of Portfolio Net Benefits ($) $1,288,873 Commission Established Goal 0.40% Portfolio Budget ($) $7,272,765 Therms Goal 2,268,882 Incentive Cap 7% Therms Achieved 2,743,851 Maximum Allowed Incentive $ $509,094 % of Goal Achieved 121% Eligible Incentive $'s $509,094 15 16 17 Prior Year True-Up Q. Do the methodology and calculations used by CEA to develop its PY 2014 true-up appear to be reasonable? -9-9

CENTERPOINT ENERGY ARKANSAS DOCKET NO. 07-081-TF DIRECT TESTIMONY OF LOVITA GRIFFIN 1 2 3 4 5 6 7 8 9 10 11 A. Yes. I reviewed the calculations used by CEA for its PY 2014 true-up and found no mathematical errors. I compared the actual expenses in PY 2014 to those approved by Commission Order No. 73 in this docket. I also verified that CEA used the appropriate carrying charge rate as approved in its last rate case, Docket No. 06-161-U. The methodology utilized by the Company in its calculation of the PY 2014 true-up appears to be reasonable. Therefore, I conclude that the PY 2014 true-up, as calculated by CEA, is materially accurate. These amounts, along with the reported actual recoveries under the PY 2014 EECR Rates, are summarized in Table 4. Table 4 Program Year Program Year True-Up Actual Revenues Actual Expenses* (Over)/Under Collection Carrying Charges Prior Year Cumulative (Over)/Under Adjustments Cumulative (Over)/Under "True-Up" (a) (b) (c)=(b)-(a) (d) (e) (f) (g)=(c)+(d)+(e)+(f) 2012 $4,659,717 $5,335,788 $676,071 $24,623 $483,983 $100,210 $1,284,886 2013 $7,967,865 $6,640,904 ($1,326,961) $9,482 $1,284,886 $78,715 $46,123 2014 $9,057,676 $6,177,104 ($2,880,572) ($156,738) $46,123 $0 ($2,991,187) *Acutal Expenses include LCFC and utility performance incentives. 12 13 14 15 16 17 18 Other Adjustments Q. Did CEA make any adjustments to its calculation of the PY 2015 Recoverable Costs? A. No. As shown in Table 1, column (e) CEA did not have any adjustments. 2015 Attachment A Q. Do the calculations used by CEA as reflected in PY 2015 Attachment A comply with prior Commission Orders in this docket? -10-10

CENTERPOINT ENERGY ARKANSAS DOCKET NO. 07-081-TF DIRECT TESTIMONY OF LOVITA GRIFFIN 1 2 3 4 5 6 7 8 9 10 11 12 A. Yes, the calculations in Attachment A appear to be consistent with CEA s 2015 Attachment A approved by Commission Order No. 73 in this docket. Based on the review as described above, I conclude that the Recoverable Cost of $5,886,393 as calculated by CEA is materially accurate. Q. If CEA s 2015 EECR Rate is approved by the Commission, what would be the impact on CEA s residential customers? A. If CEA s proposed 2015 EECR Rate is approved by the Commission, the current residential rate of $0.02020 would decrease to $0.01300 per Ccf. A residential customer consuming 50 Ccf per month would see an decrease in the EECR charge from $1.01 to $0.65. The current rates for all rate classes would change as shown in Table 5.

ENERGY EFFICIENCY ANNUAL REPORT Q. Did you review the PY 2014 Annual Report submitted by CEA? A. Yes. I have reviewed the PY 2014 Annual Report submitted by all seven of the investor owned utilities, including CEA. A summary of the utility annual reports is provided in Attachment A to my Testimony. Q. Has CEA s Annual Report been used as evidence to support its 2015 EECR Rate? -11-11

CENTERPOINT ENERGY ARKANSAS DOCKET NO. 07-081-TF DIRECT TESTIMONY OF LOVITA GRIFFIN 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 A, Yes. I verified that the PY 2014 expenses, LCFC, net energy savings, and Incentives reported in the Company s PY 2014 Annual Report were consistent with the 2015 EECR and used as evidence in the calculation of CEA s 2015 EECR Rate. Q. Did CEA remain within the Commission approved budget for PY 2014? A. Yes. CEA operated within the Portfolio Budget approved by the Commission for PY 2014. Q. Did you review the EM&V section of CEA s Annual Report? A. No, I did not. I relied on the evaluated net energy savings provided within the EM&V report, but I did not review how they were developed. The Independent EM&V Monitor (IEM) reviews and reports on the EM&V activities and efforts of each Company. The IEM Team, led by Dr. Katherine Johnson of Johnson Consulting Group, will be filing its annual report on EM&V activities to the Commission by June 1, 2015. The IEM Annual EM&V Report will provide an overview and assessment of the utilities and third-party administrators EM&V efforts. In addition to commenting on the quality of the EM&V efforts, the IEM report may also provide insights into program design and process issues which will address some of the Commission s questions regarding how effectively programs are working and ways to improve the viability of various programs. -12-12

A. I recommend that the Commission approve CEA s 2015 Attachment A in support of its annual redetermination of the EECR Rate as filed on March 31, 2015. Q. Do have any other recommendations? A. Yes. Although I have concluded that the approved methodology was used in the development of the 2015 Attachment A, I have not conducted a complete examination of the underlying data used in the development of the 2015 Attachment A. In order to avoid questions regarding Staff's right to review the underlying data used in developing the costs recovered from ratepayers, I recommend that the Commission s order explicitly state that its approval of the Company s 2015 Attachment A reserves Staff s right to subject the underlying data to ongoing compliance audits at Staff's discretion, and affirms the Commission s authority to order refunds (including the payment of carrying charges) in the event the Commission ultimately rules that any part of the program costs were not appropriate for recovery from customers. Q. Does this conclude your testimony? A. Yes, it does. -13-13

ATTACHMENT A Introduction Summary of Utility Program Year 2014 Annual Reports Section 9 Arkansas Public Service Commission s (Commission) Rules for Conservation and Energy Efficiency Programs (C&EE Rules) 1 requires all investor owned utilities (IOUs or utility) to file an annual report by May 1st of each year addressing the performance of all approved energy efficiency (EE) programs. In compliance with the C&EE rules, each investor owned electric and gas utility submitted its 2014 Annual Report consistent with the EE Standardized Annual Report Packet Versions 3.0 (SARP) 2 approved by Commission Order No. 16 in Docket No. 10-010-U. The General Staff of the Commission has prepared this Program Year (PY) 2014 Annual Report Summary. This summary provides information provided by the following seven IOUs: Electric Utilities o Entergy Arkansas, Inc. (EAI) o Southwestern Electric Power Company (SWEPCO) o Oklahoma Gas & Electric Company (OG&E) o The Empire District Electric Company (Empire) Natural Gas Utilities o CenterPoint Energy Arkansas Gas (CenterPoint) o SourceGas Arkansas Inc. (SourceGas) o Arkansas Oklahoma Gas Corporation (AOG) More details regarding each utility can be found in the individual Annual Reports filed by the utilities in each of their respective TF dockets or in the EE section of the Commission s website. 3 Beginning in 2007, all electric and natural gas utility customers in Arkansas were able to participate in EE quick start programs offered by their utility. New comprehensive programs became available in 2011 as utilities implemented their first set of three-year plans which included additional programs and expansion of existing quick start programs. With the start of the new comprehensive 1 http://www.apscservices.info/rules/energy_conservation_rules_06-004-r.pdf 2 http://www.apscservices.info/eeinfo/sarp3.0instructions.pdf 3 http://www.apscservices.info/eeannualreports.aspx 1 15

plans, the Commission also set annual savings targets for PYs 2011, 2012, and 2013. The electric utilities EE savings targets were set at 0.25%, 0.50%, and 0.75% of each electric utility s 2010 sales for 2011, 2012, and 2013, respectively. The natural gas utilities EE savings targets were set at 0.20%, 0.30%, and 0.40% of each natural gas utility s 2010 sales for 2011, 2012, and 2013, respectively. Commission Order No. 2 in Docket 13-002-U set an annual net energy savings target for PY 2014 of 0.75% for electric utilities and 0.40% natural gas utilities, using 2010 sales adjusted for Self- Direct customers as the baseline. All Commission established EE savings targets by PY are shown in Table 1. Table 1: Commission Established EE Saving Targets Program Year Electric Natural Gas Baseline Year 2011 0.25% 0.20% 2010 2012 0.50% 0.30% 2010 2013 0.75% 0.40% 2010 2014 0.75% 0.40% 2010 2015 0.90% 0.50% 2013 2016 0.90% 0.50% 2013 2 16

PY 2014 Net Energy Savings and Cost Electric Utilities In PY 2014, the combined EE program expenses by the four electric IOUs in Arkansas totaled $72.2 million dollars and resulted in net savings of 249,504 MWh. The reported EE portfolio results for each electric IOU in PY 2014, including net demand and net energy savings, actual expenses, Lost Contribution to Fix Cost (LCFC), performance incentives, and the cost-effectiveness for both the total resource cost (TRC) test and program administrator cost (PAC) test are shown in Table 2. Table 2: Reported PY 2014 Portfolio Results Net Energy Savings Cost Cost-Effectiveness Electric Utility Demand Energy Actual Performance LCFC TRC PAC MW MWh Expenses Incentives EAI 63 205,507 $59,913,755 $4,225,925 $4,581,715 1.88 2.27 SWEPCO 14 30,056 $7,611,826 $2,373,855 $721,976 2.33 2.98 OG&E 3 13,794 $4,547,081 $1,893,174 $229,548 2.50 2.33 Empire 0 147 $115,688 $20,141 $0 0.94 0.53 TOTAL Arkansas 80 249,504 $72,188,350 $8,513,095 $5,533,239 As shown above EAI, SWEPCO, and OG&E earned a performance incentive for its achieved savings in PY 2014. Those same three utilities also achieved a TRC and PAC test above 1.0. The TRC and PAC tests are two of the five cost-effectiveness tests as outlined in the California Standard Practice Manual. 4 The TRC test reflects the total benefits and costs to all customers, both participants and nonparticipants, in a utility s service territory. The TRC ratio is the net benefits of the portfolio divided by the total cost, including both the participants and the utility s costs. The PAC test reflects the total costs incurred by the program administrator (including incentive costs) and excludes any net costs incurred by the customers. The primary differences between the TRC and PAC tests are (1) the PAC test does not include any energy benefits for fuels the utility does not provide; (2) the PAC test does not include any participant contributions to the cost of the EE investment; and (3) the TRC test does 4 http://www.apscservices.info/rules/prompractice-gas-electric_pt_2.pdf Electric Utilities 3 17

not include any incentives paid by the utility to the participants. A TRC or PAC ratio above 1.0 indicates that the portfolio is beneficial. The total cost for PY 2014 reported by the utilities includes actual expenses, LCFC, and performance incentives. The total combined cost for Arkansas electric utilities in PY 2014 was $86.2 million, which includes $8.5 million of LCFC and $5.5 million in performance incentives. The cost components for each utility s total cost in PY 2014 are shown in Figure 1. Figure 1: Percentage of Total PY 2014 Cost 100% 80% 60% 40% 20% Performance Incentives LCFC Actual Expenses 0% EAI SWEPCO OG&E Empire PY 2014 Net Energy Savings Targets In PY 2014 the electric IOUs on average saved 0.75% of the annual baseline sales. EAI achieved the highest level of net energy savings at 1.14% or 151% of the target while spending 92% of its budget. SWEPCO achieved net energy savings of 1.06% or 141% of the target while spending 74% of its budget. Both OG&E and Empire failed to reach the 0.75% target; however, OG&E did achieve 85% of the target at 0.64%. This qualified OG&E for a performance incentive (the Commission rules require a minimum of 80% of goal attainment to receive an incentive). 5 A summary overview of each electric utility s EE portfolio for PY 2014 is shown in Table 3. It compares budgets to the amounts actually spent; planned and evaluated net energy savings and the level of achievement towards the established savings target.
