  2. Intertie Restoration Recommendation Paper • Expected to be released by the end of September • Will be released at the same time as the overall Intertie Framework Recommendation Paper • Intertie restoration initiatives fit within the context of the overall intertie framework • Intertie Restoration paper addresses both import and export restoration • Both initiatives will be pursued by the AESO • LSSi is the first step in restoring import capacity • It is expected other import initiatives will be pursued

  3. Intertie Restoration Policy Interpretations • Intertie Restoration services will be treated as a system service with costs allocated to load • Consistent with government transmission policy • Treats imports and exports similarly to internal loads and generators • LSSi or any other import restoration services will not confer transmission rights • Infrastructure solutions for further import restoration will also be examined

  4. Recommended LSSi Product Design • Procurement to be done through term contracts (1-3 years) • Three part price mechanism recommended (similar to standby market price structure) • Availability payment – Fixed $/MW payment based on actual consumption and willingness to be armed • Arming payment – Indexed to pool price based on volume actually armed • Trip Payment – Fixed $/MW payment based on volume tripped when frequency drops below 59.5 Hz

  5. Recommended LSSi Product Design • Availability payment is paid only when service is physically available • No payment when the load is not available due to reduced consumption and/or unwillingness to be armed • Arming payment is paid when the service is dispatched on to support import flows • Indexed to pool price • Once armed, the service is firm for the hour to support import schedule

  6. Implementation Activity • Dispatch tool being developed • Arm and disarm signal to be sent using SCADA • Participants will send the AESO armed status, current availability and future availability (next and next + 1) • AESO will arm providers as required to support scheduled import flow • Settlement to be a ‘shadow settlement’ system • Providers submit monthly invoice to the AESO • AESO performs shadow settlement to verify accuracy

  7. Implementation Activity • OPP Changes Required to OPP 312 • Arm and disarm duty for the system controller • Update import capability (Revised ATC table) • AESO will initiate consultation process on this change in the near future

  8. Next Steps • Finalize product design and initiate procurement process • Contract being developed • Procurement process will begin in the later part of Q4 • Consultation initiated on required rule changes • LSSi targeted to be in place and operational for Q2 2011
