  1. Regulatory Planning for Supply to GTA & Toronto Areas Presentation to Regulatory Affairs Standing Committee May 14, 2003

  2. Purpose Today • Overview of the GTA & Toronto Areas Supply Adequacy Issues • Need for Regulatory Planning • Regulatory Issues To Be Addressed

  3. GTA & Toronto Area Supply: Adequacy Issues • IMO’s last March’s 10-year Outlook identified the inadequacy of supply to Toronto as a significant concern. • Concern has been triggered by the assumed shutdown of Lakeview generation by 2005. • It also recognized that load growth in outlying parts of the GTA had created excessive loadings on transmission facilities. • The IMO has requested market participants to submit their solutions. Generation and transmission solutions have been proposed.

  4. GTA & Toronto Area Supply: Need for Regulatory Planning • Short time-frame • Complex, interrelated issues • Can benefit from a comprehensive approach

  5. GTA & Toronto Area Supply: Regulatory Issues • Planning process • Source of Funding • Cost and Rate Recovery • OEB Proceedings and Approvals • Environmental Permits and Approvals

  6. Appendix: Elements of the Ontario planning process for transmission adequacy • Annual assessment process (10-year Outlook) • IMO assesses resource adequacy and identifies market participant plans and forecast system constraints • IMO solicits voluntary responses to constraints (all resource types, including merchant and regulated transmission) • IMO assesses whether it must intervene to augment voluntary market responses to address constraints

  7. Appendix: Elements of the Ontario planning process for transmission adequacy • If urgency warrants IMO intervention: • IMO issues RFP to all potential resources (Generation, Demand, Transmission) • Responses (if any) are assessed by IMO for technical feasibility, and submitted to OEB review and approval • Assessment includes associated system (grid) upgrades • Currently there is no provision for the IMO to optimize among solutions, conduct cost-benefit analysis and select a preferred alternative • If no responses to RFP, IMO issues DFP to the local Transmitter (who must submit a proposed solution) • IMO assesses the DFP response, and project proceeds to OEB review for approval • Environmental approvals may be required

  8. Appendix: Elements of the Ontario planning process for transmission adequacy • Market participants may at any time file “spontaneous” applications for new resources • Independent of the IMO’s annual assessment process • Includes Generators, Demand Resources, Transmitters (merchant and regulated) • IMO assesses via CAA (Connection Assessment and Approval) process • includes Preliminary Assessment and System Impact Assessment • IMO recommendation forwarded to OEB for approval (Leave to Construct) • Note: Currently, the IMO can identify and solicit solutions for congestion constraints, but cannot intervene to force a solution
