5. MISO: An Evolving Market Ron Ryckman Senior Consultant, Customized Energy Solutions

6. Value of an Integrated System  Reliability  Market  Energy  Ancillaries (Regulation & Contingency Reserves)  Resource Adequacy  Transmission Planning  Regional Transmission Operator BEFORE AFTER

7. MISO Evolution  By the numbers:  Participants 362  Generation 132,296 MW  Peak Load 98,576 MW  Transmission 49,670 miles  Annual Settlements $18.4 billion charges

8. Voluntary Membership  Illinois split between two RTOs (MISO & PJM)  Ameren Illinois & ComEd  Both RTOs under Federal Energy Regulatory Commission (FERC) jurisdiction  Different market designs for energy, ancillaries, and resource adequacy  Market participants can move energy and capacity across the border  Different approaches to transmission planning  Entergy Plans to Join MISO (12/19/2013)  Arkansas, Mississippi, Louisiana, Texas  Add over 18,000 miles of transmission, ~40,000 megawatts of generation capacity, and ~40,000 MW of load into the MISO footprint  Generation – 69% Gas/Oil, Nuclear 20%, Coal 11%  FERC and state decisions expected mid September

9. Reliability & Markets Right mix of resources at the right locations with sufficient transmission to reliably operate the system Market Prices [Incentives] Reliable System [Adequacy] Cost-Effective Delivery of Electric Power [Costs] Transmission Limitations [Planning]

10. Resource Adequacy  Annual auction  System-wide peak  1 in 10 loss of load expectation  Deliverability matters  Zonal clearing prices (capped)  Peak Load Contribution method to track customer switching in IL  Pricing of the auction (residual market)  PJM design very different MISO Planning Year 2013/14 Auction Results $1.05 MW-Day or.03 kW-Mo Same price for all zones 96% opt-out or self-schedule MISO Planning Year 2013/14 Auction Results $1.05 MW-Day or.03 kW-Mo Same price for all zones 96% opt-out or self-schedule

11. Reliability/Deliverability Matters  MTEP (MISO Transmission Expansion Plan)  Baseline Reliability Projects  Generator Interconnection Projects  Market Efficiency Projects  Other Transmission Projects  Multi-Value Projects (MVP) Facilitate public policy objectives, such as meeting Renewable Portfolio Standards (~$5 billion)

12. Illinois Projects (MVP) -From Ameren Illinois Presentation at Williams Capital Group Midwest Utilities Seminar - 04/09/2013  Plan to invest ~$1.2 billion over 2013-2017 period  2014 construction begins  FERC & ICC review  Cost allocation through MISO charges

13. MISO Wrap-Up  Reliability  Resource Adequacy  Transmission Planning & Construction (High Voltage)  Markets  Energy  Ancillary Services  Resource Adequacy  Oversight  Federal Energy Regulatory Commission  Illinois Commerce Commission  Market Participants
