Prior to working for CenterPoint, I worked as a Market Research Analyst for American 22 General Finance for six years working primarily on customer segmentation, demographic 23 analysis, and site location analysis.

I testified before the Commission in support of CenterPoint’s Certificate of Public 13 Convenience and Necessity (“CPCN”) in Cause No. 45052, and Petitioner’s request for 14 approval of a tariff rate for Excess Distributed Generation in Cause No. 45378. 15 Additionally, I recently provided written testimony in Cause No. 44910-TDSIC-8 and in 16 Cause No. 44909-CECA 3. 17 18 19 II. PURPOSE & SCOPE OF TESTIMONY 20 21 What is the purpose of your testimony in this proceeding? 22 A. My testimony describes the analysis and results of CenterPoint’s 2019/2020 Integrated 23 Resource Plan (“2019/2020 IRP”) process. In addition, I describe and support 24 CenterPoint’s request for a CPCN to purchase and acquire the Posey County Solar 25 Project through a Build Transfer Agreement (“BTA”) pursuant to Ind. Code ch. 8-1-8.5. I 26 also describe and support CenterPoint’s proposal to enter into a Power Purchase 27 Agreement (“PPA”) with Clenera LLC’s affiliate, Rustic Hills Solar II LLC, (“Clenera”) to 28 purchase energy and capacity from a 100 megawatts alternating current (“MWac”) solar 29 project in Warrick County, Indiana (the “Warrick County Solar Project”), over a 25-year 30 term and finding the terms of the PPA reasonable and necessary. I also describe why the 31 Posey County Solar Project qualifies as a “Clean Energy Project” under Ind. Code ch. 8- 32 1-8.8. In addition, I will explain how the Levelized Rate for the Posey County Solar Project 33 will be incorporated within CenterPoint’s Clean Energy Cost Adjustment (“CECA”), which IURC Cause No. 45501 Petitioner’s Exhibit No.4 (Public) CenterPoint Page 4 of 30 1 the Commission approved on August 16, 2017, in Cause No. 44909. I describe how the 2 cost of the Warrick County Solar Project will be recovered through the fuel adjustment 3 clause (“FAC”) mechanism, including recovery of debt equivalency described in Witness 4 Brett A. Jerasa’s testimony. Finally, I describe how customer rates will be impacted by 5 the two projects. 6 7 Are you sponsoring any attachments to your direct testimony in this proceeding? 8 A. Yes.

CENTERPOINT’S 2019/2020 IRP PROCESS 27 28 Please describe how CenterPoint approached the 2019/2020 IRP. 29 A. The 2019/2020 IRP was CenterPoint’s most detailed resource planning analysis process. 30 The Company worked with several industry experts to conduct the technical analysis: Itron 31 provided the long term energy and demand forecast; 1898 and Company, a Burns and 1 Currently pending before the Commission in CECA 3. IURC Cause No. 45501 Petitioner’s Exhibit No.4 (Public) CenterPoint Page 5 of 30 1 McDonnell company (“Burns and McDonnell”), worked with CenterPoint to conduct an All- 2 Source Request For Proposals (“All-Source RFP”) and provide modeling inputs for various 3 generating resources; Black and Veatch assisted with several studies utilized to evaluate 4 numerous alternatives for existing resources; GDS provided Energy Efficiency modeling 5 inputs; and Siemens PTI, formerly Pace Global Energy Services (“Siemens PTI”) provided 6 scenario development, deterministic modeling, probabilistic modeling, and provided 7 assistance with the risk analysis. A copy of Petitioner’s 2019/2020 IRP is attached to my 8 testimony as Petitioner’s Exhibit No. 4, Attachment MAR-1 (Confidential). 9 10 Q. What process did Petitioner use in developing the 2019/2020 IRP? 11 A. Petitioner began the process by reviewing stakeholder comments from the 2016 IRP, 12 including the Director’s Report, and by carefully reviewing the Commission Orders issued 13 in connection with Petitioner’s requests for CPCNs in Cause Nos. 45052 (F.B. Culley 3 14 upgrades and CCGT) and 45086 (50 MW Troy solar). This feedback was used to formulate 15 twelve continuous improvement commitments that were shared with CenterPoint IRP 16 stakeholders in our first public stakeholder meeting on August 15, 2019, and fulfilled on 17 June 30, 2020, with the submission of the 2019/2020 IRP. In the first stakeholder meeting, 18 CenterPoint presented the analysis plan and laid out all topics to be discussed with 19 stakeholders for each of CenterPoint’s public stakeholder meetings. Figure 3.1 20 “2019/2020 Stakeholder Meetings” on page 108 of the IRP details the topics discussed in 21 each meeting, which are summarized in Figure 1 below. 22 IURC Cause No. 45501 Petitioner’s Exhibit No.4 (Public) CenterPoint Page 6 of 30 Figure 1: 2019/2020 Stakeholder Meetings October 10, December 13, August 15, 2019 June 15, 2020 2019 2019 • 2019/2020 IRP • RFP Update • Draft Portfolios • Final Reference Process • Draft Resource • Draft Reference Case and • Objectives and Costs Case Modeling Scenario Measures • Sales and Results Modeling • All-Source RFP Demand • All-Source RFP Results • Environmental Forecast Results and • Probabilistic Update • DSM MPS/ Final Modeling Modeling Results • Draft Reference Modeling Inputs Inputs Case Market • Scenario • Scenario • Risk Analysis Inputs & Modeling Inputs Testing and Results Scenarios • Portfolio Probabilistic • Preview the Development Modeling Preferred Approach and Portfolio Assumptions 1 The general process involved presenting information and gathering feedback from 2 stakeholders on key topics, including but not limited to the following: objectives, scorecard 3 development, forecasts, modeling inputs, scenario development, portfolio development, 4 technical modeling, and results. At the beginning of each stakeholder meeting, 5 CenterPoint made a point to follow up with stakeholders on input provided in the prior 6 meeting. Often stakeholder feedback was utilized, but in instances where it was not, 7 CenterPoint discussed why it was not used. The planning analysis began with an All- 8 Source RFP, which was conducted simultaneously with the IRP and was utilized as an 9 input into modeling for resource selection/portfolio development.
