QUESTIONS?
Appendix
Supplemental Background Information
(Not covered during presentation)
21
APPENDIX – AMIL PRICING ZONE
• 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)
22
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
23
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
24
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 9%
• Ameren MVPs will primarily be built by ATXI
• AIC will be responsible for modifications needed to its existing facilities
25
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
26
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
27
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
28
APPENDIX - MAP OF AMEREN MVPS
29
APPENDIX - RATE INCENTIVES
• FERC approved the following rate incentives for Illinois Rivers in
Docket No. EL10-80
– CWIP (no AFUDC)
– Abandonment (requires additional filing prior to recovery)
– Hypothetical capital structure during construction for ATXI
• FERC approved similar incentives for Spoon River and Mark Twain
Projects in Docket No. ER12-2216
