17. 17 2006 Long-Term RFP Process Safeguards

18. 18 RFP Process Safeguards l Independent Monitors l Code of Conduct l RFP Process Design and Implementation l Confidentiality Protections

19. 19 Role of Independent Monitors l ESI has retained two Independent Monitors (IMs) to assist in the development of the RFP solicitation, evaluation and selection process in support of ESI’s efforts to ensure that the RFP and its evaluation process will be objective and impartial –Process IM – Elizabeth Benson, Energy Associates –Evaluation IM – Potomac Economics (David Patton, Robert Sinclair, Michael Chiasson) l The Independent Monitors also will monitor the design of the RFP and the conduct of the RFP solicitation, evaluation, selection and contract negotiation processes to provide an objective third-party perspective in support of ESI’s efforts to ensure that all proposals are treated in a consistent fashion and that no undue preference is provided to Entergy Competitive Affiliates or self-build/self-supply options l The specific roles of each IM are described in the Scope of Work Activities of the Independent Monitors that is posted on the RFP Website

20. 20 RFP Process Safeguards l Code of Conduct –All employees of ESI, any Entergy Operating Company, or any Entergy Competitive Affiliate, including those involved in the RFP process, must adhere to the appropriate Affiliate Rules and Codes of Conduct as applicable and further outlined in the RFP –Link provided on ESI RFP website l Additional protocols –Each RFP Proposal Evaluation Team is made up of designated personnel. Team composition is overseen by the Process IM –ESI personnel involved with the 2006 Long-Term RFP evaluation process will adhere to the provisions of a confidentiality acknowledgement that governs access to and uses of information contained in proposals and proposal documents –The Self-Build Commercial Team will be segregated from the RFP proposal evaluation process l RFP Process Design and Implementation –Various elements of the RFP process have been designed to assure fair treatment of all Bidders (as described in the following slides)

21. 21 RFP Process Safeguards Communications with ESI before Proposal Submission l All issues related to the RFP should be directed to Ms. Laura Berryman, the RFP Administrator –Potential bidders wishing to communicate with the IMs may contact Ms. Benson l Any inquiries about the Entergy Transmission System should be directed to the Transmission Organization through the OASIS web site http://oasis.e- terrasolutions.com/OASIS/EES l Unapproved contact with ANY other ESI Employee for ANY purpose in connection with the RFP is prohibited, and may, depending on the circumstances, constitute grounds for disqualification l All questions from market participants relating to the RFP should be submitted through the question and answer process outlined in Section 2.5 of the RFP. The procedure for issuing questions regarding the transmission system is outlined in Section 2.6 of the RFP l ESI will have an RFP “Hotline” available from April 18th through May 19th to assist Bidders only with respect to technical questions regarding the electronic registration or proposal submission process

22. 22 RFP Process Safeguards Data Segregation l The objective of the proposal segregation process is to limit data distribution on a “need-to-know basis” within the RFP evaluation teams, and to reduce to the extent possible the distribution of confidential information l Segregation of information obtained from proposals is performed automatically by electronic processing of all proposals –Pre-formatted proposal data reports with information about proposals are prepared by the automated process prior to the distribution of reports to the evaluation teams –This process captures relevant information submitted in “Special Considerations” fields l The proposal data reports are reviewed by the Process IM before distribution to the RFP evaluation teams –This process supports the effort to keep the Bidder identity unknown to the RFP evaluation teams l Proposal data reports are limited to the data necessary for each team to perform its specific analysis –Economic Evaluation requires details regarding dispatch flexibility, pricing, availability, and mutual exclusivity of the proposals –Other evaluation processes require details regarding that specific area of evaluation (i.e., Fuel, Transmission, Credit)

23. 23 RFP Process Safeguards Communication with Bidders During Evaluation l No communication with Bidders is expected during the initial evaluation process –ESI retains the right to contact Bidders via the RFP Administrator to obtain clarification or request additional information l Bidders should direct any questions to the RFP Administrator l Any communication with Bidders will be under the supervision of the Process IM

24. 24 RFP Process Safeguards Q&A Process l The objectives of the Question and Answer Process include the following: –To ensure to the extent practicable that all Bidders have equal access to information that may be potentially relevant to their proposals –To minimize the need for either ESI or Bidders to disclose confidential information –To maintain to the maximum extent practicable the confidentiality of proprietary information that is disclosed in Bidders’ proposals or otherwise in connection with the RFP –To ensure compliance with all applicable affiliate rules and codes of conduct and other information sharing rules

25. 25 RFP Process Safeguards Q&A Process at Today’s Conference l At today’s conference, all questions will be submitted in writing –Oral responses will be provided where practicable –Written answers will be posted on the RFP Website –Written answers may contain information different from, or in addition to, information provided orally at the Conference, in which case the written answer will supercede the oral response

26. 26 2006 Long-Term RFP Overview of Resource Plan

27. 27 Supply Objectives Risk Mitigation – Supply Diversity – Mitigate the exposure to major supply disruptions that could occur from concentrated or systematic risks, for example outages of a single generation facility The supply needs that determine the resource requirements of the Operating Companies are driven by six basic resource supply objectives: Provide adequate resources to meet customer peak demands with adequate reliability Provide low cost baseload resources to serve baseload requirements (the firm load level that is expected to be exceeded for at least 85% of all hours per year) Reliability Provide efficient, dispatchable load-following resources to serve the time varying load shape levels that are above the base load requirement load levels Provide a generation portfolio that is more efficient and avoids an over-reliance on aging resources Mitigate the exposure to price volatility associated with uncertainties in fuel and purchased power costs Production Cost – Baseload Supply Requirements Risk Mitigation – Supply Diversity Production Cost – Load Following Supply Requirements Generation Portfolio Enhancement Risk Mitigation – Price Stability System Resource Needs

28. 28 Summary of Resource Requirements System Resource Needs Summary System of Resource Needs (MWs) SSRP anticipates 1500-3000 MWs of short-term and limited-term products acquired through ongoing RFP efforts. Long-term and limited-term additions include resources added to the utility portfolio since the adoption of the SSRP. Resources exclude short-term, seasonal, monthly and weekly purchases.
