BUSINESS ADDRESS. 2 3 PLEASE STATE YOUR NAME, BY WHOM YOU ARE EMPLOYED, AND YOUR A. My name is David R. Dyke. I am employed by Oklahoma Gas and Electric 4 Company ("OG&E") and my business address is 321 N. Harvey, Oklahoma City, 5 Oklahoma 73101 . 6 7 Q. PROFESSIONAL EXPERIENCE. 8 9 PLEASE DESCRIBE YOUR EDUCATIONAL BACKGROUND AND A. I am a graduate of East Central University where I received a Bachelor of 10 Science in Environmental Science. I accepted a position with the Oklahoma 11 Corporation Commission ("OCC") Public Utility Division ("PUD") in 1981 as a 12 Public Utility Specialist where I worked on rate design and fue l clause adjustment 13 audits until being appointed Fuel Procurement Manager in 1983. As the Fuel 14 Manger, I was responsib le for overseeing th e fuel and purchased power 15 adjustment clause audits for electric and natural gas public utilities in Oklahoma . 16 In 1985, I was appointed Deputy Director of the PUD and served in that position 17 for nine years. During my tenure with the PUD I managed over 100 utility cases 18 and filed testimony before the OCC in more than 30 proceedings. In 1994, I 19 joined the Oklahoma Department of Environmental Qua lity ("DEQ") as the 20 Deputy Director of the Air Quality Division and served in several leadership 21 positions with the DEQ before being appointed Director of Admin istrative 2 APSC FILED Time: 1/17/2014 3:52:11 PM: Recvd 1/17/2014 3:42:57 PM: Docket 14-007-tf-Doc. 3 1 Services in 2003. In this role , my broad respons ibilities included rule-making and 2 legislative activities , accounting and finance , human resources , information 3 techno logy, records and property management. I began my employment with 4 OG&E in October 2009. 5 6 Q. WHAT POSITION DO YOU CURRENTLY HOLD WITH OG&E? 7 A. I hold the position of Regulatory Compliance Specialist. Q. WHAT ARE YOUR RESPONSIBILITES AS REGULATORY COMPLIANCE 8 9 SPECIALIST FOR OG&E? 10 11 A. My current responsibi lities include oversight of Energy Cost Recovery ("ECR") 12 filings and activities in Arkansas and case management of Fuel Clause 13 Adjustment ("FCA") activities including the annual FCA audit and prudence 14 review in Oklahoma . I also serve as a resource in rate case and environmental 15 regulatory policy matters and monitor comp liance with regu latory filings. 16 17 Q. PUBLIC SERVICE COMMISSION ("APSC" OR "COMMISSION")? 18 19 HAVE YOU PREVIOUSLY PRESENTED TESTIMONY BEFORE THE ARKANSAS A. Yes. I fi led testimony to support the Company's compliance filing pursuant to Docket No. 10-059-U. 20 21 22 Q. WHAT IS THE PURPOSE OF YOUR TESTIMONY IN THIS PROCEEDING? 3 APSC FILED Time: 1/17/2014 3:52:11 PM: Recvd 1/17/2014 3:42:57 PM: Docket 14-007-tf-Doc. 3 1 A. The purpose of my testimony is to support changes to the ECR tariff in order to 2 provide clarification regarding the Company's participation in the Southwest 3 Power Pool Integrated Market 11 ("SPP IM") which is replacing the Energy 4 Imbalance Services ("EIS") Market. 5 6 Q. CHANGES? 7 8 HAVE YOU PREPARED TARIFF SHEETS THAT REFLECT THE PROPOSED A. Yes. Exhibit DRD-1 is a red line version of the revised ECR tariff sheets reflecting the updates described in my testimony. Exhibit DRD-2 is a clean copy of the 9 revised tariff sheets. 10 11 12 Q. OG&E's PARTICIPATION IN THE SPP INTERGRATED MARKET. 13 14 PLEASE DECRIBE THE TARIFF CHANGES PROPOSED BECAUSE OF A. Upon implementation of the SPP IM , the current EIS Market will no longer be 15 available with its current functions being performed in the new SPP IM. OG&E 16 plans to participate in the SPP IM , therefore, the ECR tariff requires updating for 17 the new market. The Company is proposing to replace EIS with SPP IM and 18 define SPP IM in the tariff. This change simply updates and clarifies the ECR 19 tariff language and formulas. 20 1 Docket No. 04-137-U, Order No. 10 Find ings and Rulings of the Commission on Joint Petition for Approval to Participate in Southwest Power Pool's Integrated Marketplace and for Declaratory Relief. 4 APSC FILED Time: 1/17/2014 3:52:11 PM: Recvd 1/17/2014 3:42:57 PM: Docket 14-007-tf-Doc. 3 1 We are also recommending the deletion of Note (7) which refers to a minimum 2 level of off-system and EIS sales revenue. Participation in the market changes 3 the Company's level of contro l over both of these sales and the historical dollars 4 used in determining the level of revenues will no longer be comparable to the s level settled in the market. Therefore this note is no longer valid . 6 7 Q. DOES THIS CONCLUDE YOUR DIRECT TESTIMONY? 8 A. Yes. 5 APSC FILED Time: 1/17/2014 3:52:11 PM: Recvd 1/17/2014 3:42:57 PM: Docket 14-007-tf-Doc. 3 ATTESTATION I do hereby swear and affirm that the foregoing is my testimony in this docket. David R.

(4) Should there be unusual circumstances associated with any Projected Energy Cost Period either the Company or the Staff may propose use of a Projected Energy Cost (PEC variable) different from that defined by this formula. (5) The fuel cost associated with the DAP incremental kWh will be deducted from fuel cost and the fuel cost associated with DAP decremental kWh will be added to fuel cost. The incremental DAP kWh will be removed from PES and the decremental DAP kWh will be added to PES. (6) The recovery of purchased energy costs associated with long-term energy resources must be approved by the Commission prior to recovery through the ECR Rider. THIS SPACE FOR PSC USE ONLY
