Hilo challenges

How are my rewards calculated?

Hilo first calculates your baseline consumption. To do this, we evaluate your consumption before each challenge –  between 1 a.m. and 4 a.m. for morning challenges and between noon and 3 p.m. for evening challenges. This is called the anchoring period.

Then we calculate the average consumption of the last 5 days of the same type (weekday or weekend), excluding any days on which there were challenges. We remove from the calculation the day when your consumption was the highest and the day when it was the lowest, giving us the average of the three most representative days.

This average consumption is then adjusted according to the anchoring period so as to obtain a consumption ratio. We then apply this ratio to the hours corresponding to the reduction phase (from 6 a.m. to 10 a.m. or from 5 p.m. to 9 p.m.).

The resulting baseline consumption is thus representative of your usual consumption and adapted to the outside temperature at the time of the challenge.   

If it is impossible to make a connection between your Hydro‑Québec meter and the Hilo hub, you will receive a lump-sum reward that is calculated based on your home’s potential energy-saving contribution as well as your participation mode for challenges.

Calculating your reward

To determine the amount of your reward, we first calculate the curtailment, which is the difference between your reference consumption and your actual consumption during the Hilo challenge (reduction phase).

The curtailment achieved during the Hilo challenge is measured in kilowatthours. To calculate the reward amount, we multiply the number of kWh by $0.55.

For example, if your total consumption during a challenge is 26 kWh and your baseline consumption is 31.4 kWh, you saved 5.4 kWh and will earn a reward of $2.97.

If your actual consumption is higher than the baseline consumption, you fail the challenge and won’t earn any rewards ($0). You cannot earn rewards when you discontinue your participation in a Hilo challenge, even while it’s under way.

Note: Your energy consumption during the preheating and recovery phases has no impact on the calculation of erasure.


Here is a typical example of a morning challenge with preheating selected in intrepid mode.

Below is the customer’s baseline consumption for this challenge, as calculated during the anchoring period.

Preheating phase*

Between 4  a.m. and 5 a.m.:       6.64 kWh

Between 5 a.m. and 6 a.m.:        9.54 kWh

Reduction phase

Between 6 a.m. and 7 a.m.:        10.41 kWh

Between 7 a.m. and 8 a.m.:        10.55 kWh

Between 8 a.m. and 9 a.m.:          4.06 kWh

Between 9 a.m. and 10 a.m.:       4.46 kWh

Total:                                                 29.48 kWh

Recovery phase*

Between 10 a.m. and 11 a.m.:   4.36 kWh

To pass this challenge, the customer’s total consumption cannot exceed 29.48 kWh, which is equivalent to the total baseline consumption calculated during the reduction phase, between 6 a.m. and 10 a.m.

Below is the customer’s actual consumption during the challenge.

Preheating phase*

Between 4  a.m. and 5 a.m.:       8.05 kWh

Between 5 a.m. and 6 a.m.:        9.61 kWh

Reduction phase

Between 6 a.m. and 7 a.m.:        8.34 kWh

Between 7 a.m. and 8 a.m.:        4.91 kWh

Between 8 a.m. and 9 a.m.:        1.75 kWh

Between 9 a.m. and 10 a.m.:     2.07 kWh

Total:                                                17.07 kWh

Recovery phase*

Between 10 a.m. and 11 a.m.:   4.71 kWh

For this challenge, the customer’s total consumption during the reduction phase is 17.07 kWh, which represents a curtailment of 12.41 kWh compared to the baseline consumption (29.48 - 17.07 = 12.41).

As a result, the customer will earn a reward of $6.83 (12.41 kWh x $0.55 = $6.8255).
