Intertie Restoration Update
September 15, 2010
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
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
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
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
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
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
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
