Both AIC and ATXI are transmission owning subsidiaries of Ameren Corporation, as well as a MISO Transmission Owners (TOs)
AIC will continue to build and own traditional reliability projects
ATXI is in the process of building and will own new regional transmission projects
Prairie Power, Inc. became a TO in the AMIL pricing zone effective June 1, 2013.
The sum of all there Attachment O net revenue requirements equals the total revenue requirement for AMIL pricing zone to be collected under Schedule 9 (NITS)

24. Appendix - MISO ATTACHMENTs O, GG & MM
Calculate rates for Schedules 9, 26 & 26-A
Attachment GG - Schedule 26
Attachment MM - Schedule 26-A
Attachment O - net revenue requirement billed under Schedule 9
Schedules 26 and 26-A are billed by MISO
Schedule 9 is billed by Ameren

25. Appendix - MISO ATTACHMENT gg
Cost Recovery for certain Network Upgrades
Eligible projects
Market Efficiency
Generator Interconnections
Cost shared based upon project type
MISO-wide based on load
Subregional based on LODF (Line Outage Distribution Factor)
AIC has four Attachment GG projects completed
Two additional projects under construction
These projects were approved by MISO under prior Tariff provisions which allowed limited cost sharing for certain reliability projects

26. Appendix - MISO ATTACHMENT MM
Cost recovery for Multi-Value Projects (MVPs)
Very similar format as Attachment GG
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 10%
Ameren MVPs will primarily be built by ATXI
AIC will be responsible for modifications needed to its existing facilities

27. Appendix - MISO ATTACHMENT O, GG & 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
Revenue Credits
Point-to-Point revenue in Schedules 7 & 8
Rental revenue
Revenue from generator interconnections

28. 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

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 10% of each MVP no matter where project is located or who builds it
