1 2013 Transmission Stakeholder Meeting Ameren Transmission Company of Illinois and Ameren Illinois Company October 17, 2012

2 2 AGENDA Main Purpose is to review ATXI and AIC Projected 2013 Transmission Rate Calculations Background on Attachment O, GG & MM Overview of MTEP and MVPs Forward Looking Rates Approved Incentives ATXI Comparison to Current Revenue Requirement AIC Comparison to Current Revenue Requirement 2013 AMIL Pricing Zone NITS Charge

3 3 AIC AND ATXI Both AIC and ATXI are transmission owning subsidiaries of Ameren Corporation, as well as MISO Transmission Owners (TOs) The sum of their Attachment O net revenue requirements equals the total revenue requirement for AMIL pricing zone to be collected under Schedule 9 (NITS) AIC will continue to build and own traditional reliability projects ATXI is in the process of building and will own new regional transmission projects

4 4 MISO ATTACHMENTS O, GG & MM Calculate rates for Schedules 9, 26 & 26-A Attachment GG - Schedule 26 (page 5) Attachment MM - Schedule 26-A (page 6) Attachment O - net revenue requirement billed under Schedule 9 (page 7) Schedules 26 and 26-A are billed by MISO Schedule 9 is billed by Ameren

5 5 MISO ATTACHMENT GG Cost Recovery for certain Network Upgrades Eligible projects Baseline Reliability 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 three Attachment GG projects completed ATXI has no Attachment GG projects

6 6 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 9% Ameren MVPs will primarily be built by ATXI AIC will be responsible for modifications needed to its existing facilities

7 7 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 Point-to-Point revenue in Schedules 7 & 8 Rental revenue Revenue from generator interconnections Questions on Tariffs?

8 8 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

9 9 MISO MVPS Brief history of development Began investigating value added expansion in 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

10 10 MAP OF AMEREN MVPS

11 11 FORWARD LOOKING RATES Rates better reflect current costs Implemented by several MISO TOs Requires true-up to actual year costs New calculations based on projected 2013 data Rate base items -13 month average balance Interest on over/under recovery 2013 true-up calculated in 2014 and reflected in 2015 rates FERC approved forward looking rates for ATXI effective March 1, 2012 AIC filed request at FERC in July 2012 and expects an Order by the end of 2012.

12 12 FORWARD LOOKING RATES TIMELINE September 1, 2012 Calculate 2013 revenue requirements for AIC & ATXI October 31, 2012 Meet with Customers to discuss rate input projections and cost detail January 1, 2013 New rates in effect July 1, 2013 Calculate and post 2012 true-up (Only ATXI in 2013) September 1, 2013 Calculate 2014 revenue requirements for AIC & ATXI Includes 2012 true up with interest for ATXI October 31, 2013 Meet with Customers to discuss rate input projections and cost detail January 1, 2014 New rates in effect based on 2014 projections and 2012 true-up for ATXI

13 13 RATE INCENTIVES FERC approved the following rate incentives for Illinois River in Docket No. EL10-80 –CWIP (no AFUDC) –Abandonment (requires additional filing prior to recovery) –Hypothetical capital structure during construction for ATXI July 2012 filing requested similar incentives for Spoon River and Mark Twain Projects

29 29 AIC PROJECTIONS FOR 2013 Modifications to Existing Facilities Category CAPEXProjectsDescription Reliability/aging infrastructure replacement $178 million196 These projects are primarily driven by the need to upgrade the transmission system based on meeting NERC standards or Ameren Planning Criteria and Guidelines. The NERC TPL standards set forth a set of tests that a transmission system must meet for a list of plausible scenarios, including contingent scenarios. Ameren Planning Criteria and Guidelines (C&G) are filed each year at FERC and constitute an additional, or complementary, set of tests that the transmission system must meet. Clearance for planned line rating $127 million54 These projects are primarily driven by the need to upgrade the transmission system to support expected flows on the transmission circuits. Load growth, plant additions/retirements, and flow changes due to future system expansions are primary inputs into the decision to either increase ground clearances using existing wire or in some cases, increasing ground clearances with wire replacement, in order to achieve higher circuit ratings. Right of way expansion$22 million38 These projects are driven by the need to increase the rights and rights-of-way associated with 40 transmission corridors. The primary benefit of this set of projects is increased reliability of the system in the area of vegetation. In many cases, the existing rights-of-way are much narrower than the widths specified in Ameren's Planning Criteria and Guidelines for reliable circuit operation. The 2003 blackout and the recent 2011 Northeast US major outage event had vegetation as an incipient cause. After both events, and with the adoption of the FAC-003 standard, FERC has emphasized the need for increased vegetation management efforts which these projects support. Improved Reliability$31 million36 These projects are driven by the need to address reliability concerns driven by system topology, configuration, or condition. Operating issues, including outages, usually identify these kinds of projects. The majority of these projects involve additions of equipment in substations, e.g. relaying and/or circuit breakers.
