This option for Rate L or LG customers provides an opportunity to consume electricity in excess of your normal consumption in off-peak hours to meet short-term or exceptional needs.
The price applicable to additional electricity, which covers both power and energy, varies month to month and reflects Hydro-Québec Distribution’s marginal supply cost. It cannot be lower than 4.66 ¢ per kilowatthour.
Energy billed as additional electricity is calculated in 15-minute blocks.
Hydro-Québec will inform you of the price of additional electricity 7 business days prior to the start of each calendar month. The price remains the same for the full month.
To take advantage of this option, you must apply to Hydro-Québec at least 5 business days prior to the start of the consumption period.
The option goes into effect at the beginning of the consumption period, subject to an agreement on reference power and Hydro-Québec's acceptance.
You must agree to adhere to the additional electricity option for a whole consumption period.
