10. 10 Powers of the OPA a.To enter into contracts relating to the adequacy and reliability of electricity supplies b.To enter into contracts relating to the procurement of electricity supply and capacity in or outside Ontario c.To enter into contracts relating to the procurement of supply and capacity using alternative or renewable energy sources

11. 11 Powers of the OPA d.To enter into contracts relating to the procurement of reductions in electricity demand and the management of electricity demand e.To take steps to facilitate the provision of services relating to: (i)electricity conservation and the efficient use of electricity; (ii)electricity load management; or (iii)use of cleaner energy sources f.To enter into contracts with electricity distribution companies regarding (i), (ii) and (iii) above.

12. 12 Powers of the OPA g.To take steps to ensure adequate transmission capacity h.To act as settlement agent for payments relating to prescribed generation assets (owned by OPG) – may be outsourced to IESO

13. 13 IESO Objects and Character a.To enter into agreements with transmitters giving the authority to direct the operation of their transmission systems; b.To direct the operation and maintain the reliability of the IESO-controlled grid;

14. 14 IESO Objects and Character c. To participate in the development of standards and criteria relating to the reliability of transmission systems; d. To work with the responsible authorities outside Ontario to co-ordinate the IESO’s activities with their activities;

15. 15 IESO Objects and Character e.To collect and provide to the OPA and the public information relating to the current and short-term electricity needs of Ontario and the adequacy and reliability of the integrated power system to meet those needs; and f.To operate the IESO-administered markets.

16. 16 Ontario Energy Board Objects: 1. To protect the interests of consumers with respect to prices and the adequacy, reliability and quality of electricity service. 2.To promote economic efficiency and cost effectiveness in the generation, transmission, distribution, sale and demand management of electricity and to facilitate the maintenance of a financially viable electricity industry.

17. 17 Ontario Energy Board  Market Surveillance - existing Market Surveillance Panel of IMO continued under OEB  Market Rules - OEB reviews and approves amendments

18. 18 Ontario Energy Board  Procurement – review OPA’s proposed process (payments under contracts are deemed to be approved by the OEB)  Integrated Plan – review and approve OPA proposed plan

19. 19 Regulated Price Plan Regulated Price Plan (“RPP”) for Small Volume and Designated Customers based on:  Certain OPG generation assets (regulated and price-capped)  Legacy generation contracts with non-utility generators (“NUGs”)  OPA contracts a.300 MW Renewable b.2500 MW Clean Energy (gas and other) c.1000 MW Renewable

20. 20 Regulated Price Plan  OPA variance accounts  Wholesale market price forecast

21. 21 Components of Total RPP Supply Cost

22. 22 Other Current Initiatives  Eliminate 7,500 MW of coal-fired generation capacity  5,000 MW of new capacity by 2007 Renewable and Clean Generation and Demand-Side RFPs Expansion of Beck Tunnel at Niagara Falls Refurbishment of Nuclear Generation at Pickering and Bruce

23. 23 Other Current Initiatives  OPA working on Integrated Power System Plan Future of Nuclear NIMBY, NOPE, BANANA  e.g. York Region  Transmission Interconnection with neighbouring Provinces

24. 24 Other Current Initiatives  Conservation and Demand Management Initiatives $160M being spent by electricity distribution companies  Smart Meters and Time-of Use Pricing Goal: 8000,000 Smart Meters by December 31, 2007 Smart Meters for all Ontario consumers by December 31, 2010
