Note: The bottled generation values indicated in the table are capacity values calculated at the hour of weekly peak.
In real time operation, the actual amount of bottled generation will depend on many conditions prevailing at the time,
including the local generation levels, overall generation dispatch and the direction and levels of flows into and out of
Ontario.
Zonal information is found on page 6 of the Ontario Transmission System document.
