10. SYSTEM PLANNING 10 Role of Lexecon (cont.) Seeks to ensure objectivity and impartiality of the RFP process through the oversight and monitoring of the following: –Solicitation Process Receipt of actual “Notice of Intent to Submit Proposal” from prospective Bidders Oversight of opening of all proposals Classification and distribution of Proposal information –Evaluation Process Review of evaluation processes and criteria prior to receipt of proposals Monitoring of actual evaluation process –Selection Process Monitoring and review of final portfolio selections

11. SYSTEM PLANNING 11 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 confidential 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. Objectives

12. SYSTEM PLANNING 12 Communications with ESI regarding RFP issues before Proposal Submission For all purposes related to the RFP, except the submission of questions relating to the Entergy Transmission System, there is only ONE contact - Julie Ell. 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. 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. All questions from market participants relating to the RFP should be submitted through the question and answer process outlined in Section 2.6 of the RFP. The procedure for issuing questions regarding the transmission system is outlined in Section 2.7 of the RFP.

13. SYSTEM PLANNING 13 Q& A Process at the Technical Conference At today’s technical conference, questions will be submitted in writing –Oral responses will be provided where practicable at the technical conference –Written answers in any case will be posted on the Entergy RFP website –Written answers may contain information different from or in addition to information provided orally at the technical conference, in which case the written answer will supercede the oral answer

14. SYSTEM PLANNING 14 Question and Answer Process ESI will respond to market participant’s questions and requests for clarification or additional information relating to the RFP. The Entergy RFP website will be the official information source for accessing information relating to the RFP. All questions and answers will be posted on the RFP website. Responses will not be sent directly to Bidders who have submitted questions. Therefore, Bidders are encouraged to check the website periodically. All information contained in a question that is necessary for a complete articulation of the question will be posted on the website. ESI will attempt to redact information that would identify the Bidder and other information that Bidders are precluded from disclosing to other Bidders pursuant to the Proposal Submission Agreement (Appendix C to the RFP). (It would be preferable for Bidders to redact such information prior to submitting a question.) Although a proposal submitted pursuant to this RFP process is considered to be confidential, and will be given the protections described in Section 2.10 of the RFP, other information supplied by potential Bidders will not be considered to be confidential unless particular arrangements have been made for the submission of such information pursuant to a suitable confidentiality agreement. A potential Bidder should not submit questions to ESI containing confidential Bidder information without following the procedures specified in Section 2.6 of the RFP.

15. SYSTEM PLANNING 15 Protection of Confidential Information in the Q&A Process ESI’s preference is to avoid the need for ESI or Bidders to disclose confidential information. ESI does not expect that Bidders will need to include confidential information in questions relating to the RFP, and urges potential Bidders not to do so. If a Bidder believes that it must submit a question containing confidential information, then: –the Bidder must notify ESI in writing of the purpose of the question and the nature of the confidential information contained in that question, and –ESI, without receiving any confidential information, will then determine whether the disclosure of such information is necessary or can be avoided for purposes of the RFP process. If ESI determines that it is necessary for either ESI or any Bidder to submit confidential information in connection with the Q&A process, then such information may be provided pursuant to a suitable confidentiality agreement. Confidential Bidder information contained in a question or in a response to a question will only be disclosed to the Bidder who asked the question and to which the confidential information relates. A response containing confidential ESI information (but not any confidential Bidder information) will be sent to all Bidders who execute the applicable confidentiality agreement. Please review carefully Sections 2.6 and 2.7 of the RFP, as they describe in detail the procedures that ESI will follow.

36. SYSTEM PLANNING 36 The principal topics of this discussion are : Overview of Evaluation Method Key Evaluation Factors for Product Categories Utilized in the Proposal Evaluation Process Factor Evaluation of Proposals Economic Evaluation of Proposals Development of Supply Portfolio Alternatives Consistent with Resource Supply Planning Objectives and Constraints Comprehensive Cost and Operational Analysis Overview Of Discussion

37. SYSTEM PLANNING 37 Evaluation Method Overview The proposal evaluation process will be conducted by the Proposal Evaluation Team, with oversight from the Supply Procurement Executive Team. The Proposal Evaluation Team will evaluate proposals and develop supply portfolio alternatives to be presented to the Operating Committee for its decision regarding procurement of resources for 2003 needs and beyond. The Proposal Evaluation Team will use a pre-defined evaluation process. Each proposal will be evaluated using the proposal evaluation criteria and methodology established prior to receipt of the proposals. Proposals will be opened and reviewed for compliance with threshold requirements as specified in the RFP prior to the evaluation of any proposals. The primary consideration in the evaluation of individual resource proposals will be an objective evaluation of the economic impacts of a proposal on Entergy system total production costs (“Economic Evaluation”).

38. SYSTEM PLANNING 38 Evaluation Method Overview Key proposal factors that cannot be easily included in the Economic Evaluation (such as credit, gas supply and flexibility, potential transmission issues, etc.) will be evaluated using pre-defined procedures, criteria, and scoring systems (“Factor Evaluation”). A “Portfolio Evaluation Model” will be used to identify a portfolio of proposals that result in the lowest evaluated production cost consistent with constraints developed from the Resource Supply Objectives and the targeted product mix requirements. This model will also be used to evaluate “sensitivity cases” associated with each Portfolio Alternative considering the impacts of various constraints. The Proposal Evaluation Team will select a set of the Evaluated Portfolio Alternatives for possible presentation to the Operating Committee for its review and decision (“Supply Plan Alternatives”). Supply Plan Alternative cases will be further evaluated to assess the integrated effect of each alternative portfolio of proposals upon total system production costs, transmission issues, and the financial impact upon the Operating Companies. Lexecon will oversee the various steps in the Evaluation process.

39. SYSTEM PLANNING 39 Key Evaluation Factors for Product Categories Utilized in the Proposal Evaluation Process The key price, cost and performance factors that will influence selection include: Non-fuel annual revenue requirements Energy price as a function of heat rate curve and operating level Expected and historical availability factor Dispatch flexibility (minimum run levels, start-up costs and start-up times, etc.) An assessment of transmission impacts including: constraints on dispatch; the potential for the resource to qualify as a firm network resource; any estimated transmission costs (or avoided transmission costs associated with qualifying the resource for firm network service); and the ability of non-firm resources to deliver into multiple Entergy geographic load areas, Fuel supply availability and flexibility, The Bidder’s credit quality and willingness to offer credit security, if needed, and An assessment of operational issues including but not limited to environmental compliance and risks, unit operating history, and experience of the plant operator.

40. SYSTEM PLANNING 40 Factor Evaluation of Proposals The operational performance of proposals will be assessed by factor evaluators using evaluation methodology that will include examination of features of the proposal response that are difficult to translate into economic parameters but which can be used to differentiate relative benefits of resource alternatives. A point scoring system will be established to reflect relative performance of one or more non-economic factors. Each proposal will be assigned an overall point score for each factor (“Factor Evaluation Score”) using the pre-established factor evaluation procedure.

41. SYSTEM PLANNING 41 Factor Evaluation of Proposals (cont.) The Factor Evaluation Score will be recorded on a Factor Evaluation Scorecard. Performance factors will include (but are not limited to) features such as: –Credit Issues – Compliance with the corporate risk management processes and limits for exposure to counterparties in transactions. –Gas Supply Issues – Issues such as fuel supply flexibility (e.g. number of and availability of capacity in pipelines serving facility) and fuel supply flexibility for daily load following. –Unit Commitment and Dispatching Issues – Issues such as ramp rate for units for load following and the availability of AGC for generation control. –Transmission Issues – Issues such as resource location relative to previously identified transmission constraints, potential limitations on economic dispatch, exposure to single contingency event risks, etc. –Operational Issues – Issues such as environmental compliance, unit operating and maintenance history, staffing and labor issues, and bidder experience in developing and /or operating projects that are of a comparable size and technology to the resource being proposed.

42. SYSTEM PLANNING 42 Economic Evaluation of Proposals The Economic Evaluation consists of two steps: –The ranking of individual proposals based upon their individual impact upon Entergy System total production costs; and –The development and evaluation of supply portfolios consisting of a combination of proposals meeting the overall supply requirements and the objectives established by the Operating Committee for resource supply. The economic evaluation of individual proposals results in the ranking of individual proposals within product groups and product categories based upon the incremental economic impact of each proposal on the total production cost of the Entergy System. The results include a “Product Category Supply Cost Curve” that can be used to illustrate the proposal responses and to evaluate alternative product mix portfolio alternatives.

43. SYSTEM PLANNING 43 Economic Evaluation of Proposals (cont.) The primary analytical tool for the product category economic comparison will be a “PROSYM Proposal Evaluation Model” production costing model that will utilize information provided in the proposal response to examine the proposal’s incremental total production cost impact on Entergy System production costs The economic performance evaluation methodology will consider multiple Evaluation Scenarios for each proposal to capture the impact of uncertainties resulting from “uncontrollable cost drivers” such as gas prices, the future price and availability of economy or other power purchases, or other significant factors. The resulting economic analysis of the total production cost for individual proposals will be consolidated into a Product Category Economic Ranking (Product Category Supply Cost Curve). Factor evaluations will also be considered in this ranking, particularly with respect to proposals that have identical or very similar economic impacts.

44. SYSTEM PLANNING 44 Development of Supply Portfolio Alternatives Consistent with Resource Supply Planning Objectives and Constraints The proposal evaluation process will produce a set of Supply Plan Alternatives to be presented to the Operating Committee representing combinations of proposal responses in several product categories that meet the Resource Supply Objectives. Once individual proposals have been evaluated by product category and product group on both economic and qualitative factors, several potential portfolio alternatives that meet the Supply Procurement Plan Objectives will be developed through analysis that seeks to select the optimum set of resources to minimize total Entergy System production costs given specified constraints and objectives.

45. SYSTEM PLANNING 45 Development of Supply Portfolio Alternatives Consistent with Resource Supply Planning Objectives and Constraints (cont.) A “Portfolio Evaluation Model” (an integer programming model, which is a type of linear programming optimization model appropriate for evaluating discrete proposal packages) will be used to select a portfolio of proposals that result in the lowest evaluated total production cost consistent with constraints developed from the Resource Supply Objectives and the targeted product mix requirements for the Portfolio Alternative case. This model uses each proposal’s total production cost impacts as determined in the Economic Evaluation along with constraints based upon the Supply Resource Objectives and the targeted product mix to determine the lowest cost combination of proposals satisfying the constraints. This model will also be used to evaluate “sensitivity cases” associated with the Portfolio Alternative considering the impacts of various constraints. For each Portfolio Alternative evaluated, the PROSYM Proposal Evaluation Model will be used to assess the impact of the combined proposals included in the Portfolio Alternative upon the Entergy System’s total production cost.

46. SYSTEM PLANNING 46 Comprehensive Cost and Operational Analysis The Proposal Evaluation Team will select a limited set of Evaluated Portfolio Alternatives for possible presentation to the Operating Committee for its review and decision (“Supply Plan Alternatives”). Supply Plan Alternative cases will be further evaluated to assess the impacts of the entire portfolio of proposals upon total system production costs, transmission flows, overall credit risk of the portfolio, fuel supply risks, and the financial impact upon the Operating Companies' revenue requirements. The results of these evaluations will be summarized and included in the documentation for each Supply Plan Alternative. The Supply Plan Alternatives, along with associated analyses, sensitivities and recommendations, will be presented first to the Supply Procurement Executive Committee and then to the Operating Committee for its review. Additional studies may be requested. Based upon the Supply Plan Alternatives and associated analyses, the Operating Committee will select the resources to be acquired and determine the participation in resources by each Operating Company.
