1 2013 Transmission Stakeholder Meeting Ameren Transmission Company of Illinois and Ameren Illinois CompanyOctober 17, 2012
2 AgendaMain Purpose is to review ATXI and AIC Projected 2013 Transmission Rate CalculationsBackground on Attachment O, GG & MMOverview of MTEP and MVPsForward Looking RatesApproved IncentivesATXI Comparison to Current Revenue RequirementAIC Comparison to Current Revenue Requirement2013 AMIL Pricing Zone NITS Charge
3 Aic and AtxiBoth 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 projectsATXI is in the process of building and will own new regional transmission projects
4 MISO ATTACHMENTs O, GG & MM Calculate rates for Schedules 9, 26 & 26-AAttachment 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 MISOSchedule 9 is billed by Ameren
5 Cost Recovery for certain Network Upgrades Eligible projects MISO ATTACHMENT ggCost Recovery for certain Network UpgradesEligible projectsBaseline ReliabilityMarket EfficiencyGenerator InterconnectionsCost shared based upon project typeMISO-wide based on loadSubregional based on LODF (Line Outage Distribution Factor)AIC has three Attachment GG projects completedATXI has no Attachment GG projects
6 Cost recovery for Multi-Value Projects (MVPs) MISO ATTACHMENT MMCost recovery for Multi-Value Projects (MVPs)Very similar format as Attachment GGCriteria for being consideredDeveloped through planning process and support energy policyMultiple types of economic value across multiple pricing zones with benefit to costs > 1Address at least one:Projected NERC violationEconomic-based issueCost shared across MISO based on loadAMIL Zone is approximately 9%Ameren MVPs will primarily be built by ATXIAIC will be responsible for modifications needed to its existing facilities
7 MISO ATTACHMENT O, GG & MM All transmission costs included in Attachment O calculationSchedule 9 based on net revenue requirement – reductions for:Costs recovered in Schedules 26 & 26-APoint-to-Point revenue in Schedules 7 & 8Rental revenueRevenue from generator interconnectionsQuestions on Tariffs?
8 Miso transmission expansion plan (MTEP) Developed on an annual basis building upon previous analysisMISO, Transmission Owners & StakeholdersIncludes subregional planning meetingsMTEP goalsEnsure the reliability of the transmission systemEnsure compliance with NERC StandardsProvide economic benefits, such as increased market efficiencyFacilitate public policy objectives, such as meeting Renewable Portfolio StandardsAddress other issues or goals identified through the stakeholder processMultiple future scenarios analyzedEnd result – comprehensive, cohesive plan for MISO footprintMTEP approved by MISO Board of Directors
9 Brief history of development MISO MVPSBrief history of developmentBegan investigating value added expansion in 20032008 Regional Generation Outlet Study (RGOS) - formed basis of Candidate MVP portfolioPortfolio refined due to additional analysisMISO approved portfolio of 17 ProjectsSeven transmission line segments (MTEP proj numbers) in Ameren territoryAmeren identifies these three projects as:Illinois Rivers (four line segments)Spoon RiverMark 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
11 Rates better reflect current costs Implemented by several MISO TOs Forward looking ratesRates better reflect current costsImplemented by several MISO TOsRequires true-up to actual year costsNew calculations based on projected 2013 dataRate base items -13 month average balanceInterest on over/under recovery2013 true-up calculated in 2014 and reflected in 2015 ratesFERC approved forward looking rates for ATXI effective March 1, 2012AIC filed request at FERC in July 2012 and expects an Order by the end of 2012.

29 Modifications to Existing Facilities AIC Projections for 2013Modifications to Existing FacilitiesCategoryCAPEXProjectsDescriptionReliability/aging infrastructure replacement$178 million196These 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 million54These 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 million38These 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 million36These 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.
