Let’s talk about AQEW.
What is this and why does it matter?
There are two numbers that are important to understand in the generation of Global Adjustment five coincident peaks in power (5CP) – Ontario Demand and AQEW (Allocated Quantity of Energy Withdrawn.) Ontario Demand is the number that is posted in real time that shows the rise and fall of power usage in Ontario; while it is useful to get a sense of when a peak might be, it is not the actual number that the peak is based upon. Enter the AQEW.
AQEW is the number that is verified by the IESO (Ontario’s power system manager) and published 20 business days after the original peak. This is the number that the peak is actually calculated against and it often differs from the Ontario Demand number. (see table below)
What does this mean? Most Peak Alert Services use Ontario Demand as their key metric of prediction, which is simply not as accurate as using AQEW. When choosing your Peak Alert service, calculations around AQEW are key.
Let’s Compare…
2018 Top 5 Ontario Demand
| Date | HE | Ont Demand |
| 5-Sep-18 | 18 | 23240 |
| 5-Jul-18 | 16 | 23045 |

| 28-Aug-18 | 17 | 21989 |
| 4-Sep-18 | 17 | 21885 |
Even though AQEW is what a peak is calculated with, our competitors repackage this Ontario Demand data for their alert systems. As you can see, this data is not relevant in deciding peak hour.
