1. IMO Perspective on Reliability A presentation to the IEEE Toronto Section Forum on Reliable Power Grids in Canada by Dan Rochester, Section Head - Assessments Independent Electricity Market Operator October 3, 2003

2. August 14, 2003

3. ONTARIO The events described here, and those not fully catalogued, may change as the investigation progresses. Full document available at http://www.doe.gov 11:05 AM - 3:13 PM EST

4. Ontario Demand

5. Affected Area 300 MW Load 1200 MW Generation Smoky 30 MW 40 MW Load 720 Generation Des Joachims 20 MW 800 MW Load 480 MW Generation 320 MW 680 MW To New York 900 MW

6. Restoration Paths

8. “…to maintain the reliability of the IMO-controlled grid…” “…to participate in the development by any standards authority of standards and criteria relating to the reliability of transmission systems…” Supporting Activities: –resource (MW/MVAr) and transmission needs identification (IMO Outlooks) –connection assessments of new facilities –comprehensive reviews of transmission and generation adequacy (NPCC) IMO’s reliability role

9. Assessing New Connections Generation, Load, Transmission IMO assesses projects approval if no adverse impact conditional approval if remedial measures required [coordination of assessments approaches a planning function]

10. 10-Year Outlooks influence investment –resource adequacy, transmission adequacy, risks and requirements Looking out 10-Years

11. 18-Month Outlooks influence operations –resource adequacy, outage planning, inter-tie benefits Looking out 18-Months

12. What we see in the Outlooks Supply improving

13. What we see in the Outlooks additional supply/ demand response req’d

14. What we see in the Outlooks generation fleet aging

15. What we see in the Outlooks transmission reinforcement required
