Global Adjustment for Class A

Class A customers who participate in the Industrial Conservation Initiative (ICI) pay Global Adjustment (GA) based on a percentage of their contribution to the top five Ontario peaks over a 12-month base period.


Tracking the Current Base Period

This graph and table below show the pre-dispatch Ontario demand for the next 24 hours, and will help Class A customers identify whether the forecasted peak demand could be a new Top 10 Ontario Demand peak. Ontario Demand is the best indicator of the coincident peaks for real-time tracking.

​Real Time Data for Tracking

Top Ten Ontario Demand Peaks to Date

This table provides a real-time snapshot of the highest Ontario Demand values for the current base period that can be used to track future potential peaks. The precise hours used for ICI settlement may change based on the adjusted AQEW values as listed in the adjacent table.

Since May 1, 2016

Verified Ontario Demand Data

Adjusted Allocated Quantity of Energy Withdrawn (AQEW) Peaks to Date

ICI peaks are confirmed using adjusted AQEW peaks, a more precise, verified value. These values are published 20 business days after the trade date and only the highest demand hour of the day is used.

AQEW values for ICI are adjusted to omit the net energy withdrawn by Beck PGS, Fort Frances, and for ancillary services.

At the end of the base period, the top five AQEW hours will be used to determine the demand peaks (coincident peaks) to calculate GA allocation for the next billing period. To find the top five demand peaks for the last base period, and how to calculate your peak demand factor, visit Peak Demand Factor and the GA.
