APPENDIX - MISO ATTACHMENT MM

• Cost recovery for Multi-Value Projects (MVPs)• Criteria for being considered

• Developed through planning process and support energy policy• Multiple types of economic value across multiple pricing zones with

benefit to costs > 1• Address at least one:

• Projected NERC violation• Economic-based issue

• Cost shared across MISO based on load• AMIL Zone is approximately 9%

• Ameren MVPs will primarily be built by ATXI• AIC will be responsible for modifications needed to its existing facilities

20

APPENDIX - MISO ATTACHMENT O & MM

• All transmission costs included in Attachment O calculation • Schedule 9 based on net revenue requirement – reductions for:

• Costs recovered in Schedules 26 & 26-A• Since ATXI has no Attachment GG projects, there is no deduction for 26

• Revenue Credits• Point-to-Point revenue in Schedules 7 & 8• Rental revenue• Revenue from generator interconnections

21

APPENDIX - MISO TRANSMISSION EXPANSION PLAN (MTEP)

• Developed on an annual basis building upon previous analysis• MISO, Transmission Owners & Stakeholders• Includes subregional planning meetings

• MTEP goals• Ensure the reliability of the transmission system• Ensure compliance with NERC Standards• Provide economic benefits, such as increased market efficiency• Facilitate public policy objectives, such as meeting Renewable Portfolio

Standards• Address other issues or goals identified through the stakeholder process

• Multiple future scenarios analyzed• End result – comprehensive, cohesive plan for MISO footprint

• MTEP approved by MISO Board of Directors

22

MISO MVPS

• Brief history of development• Began investigating value added expansion in 2003• 2008 Regional Generation Outlet Study (RGOS) - formed basis of

Candidate MVP portfolio• Portfolio refined due to additional analysis

• MISO approved portfolio of 17 Projects• Seven transmission line segments (MTEP proj numbers) in Ameren territory• Ameren identifies these three projects as:

• Illinois Rivers (four line segments)• Spoon River• Mark Twain (two line segments)

• Broadly cost-shared, AMIL pricing zone allocated 9% of each MVP no matter where project is located or who builds it
