July and August were very hot months and for the Industrial Conservation Initiative (ICI) Class A program, five very strong peak hours were established. The first week of September is expected to remain hot and, with school starting and less vacations, it is possible that a new peak will contribute to the top five adjusted Allocated Quantity of Energy Withdrawn (AQEW) peak hours.
According to the IESO forecast, the only other month we can expect a peak Ontario demand hour is in January 2019. This is under normal weather conditions. For extreme weather conditions it is still possible for demand peaks to occur in the shoulder months of September, December and February.
