Structure of the option
The price applicable to additional electricity, which covers both power and energy, varies month to month and is based on Hydro-Québec Distribution’s marginal supply costs.
It cannot be lower than 5.53¢ per kilowatthour.
Lower limit for the price of additional electricity
The price of additional electricity cannot be lower than the average price at Rate M, expressed in ¢/kWh, based only on the second-tier energy price for 25-kilovolt service and a 100% load factor.
- Billing of the reference power and corresponding energy consumption is based on the prices and conditions for the applicable rate DP, M or G-9.
- All excess consumption is billed at the applicable rate for additional electricity.
The reference power reflects the customer’s normal consumption profile at the applicable rate (DP, M or G-9). It is expressed in kilowatts (kW).
Upon receiving a request for the additional electricity option for photosynthetic lighting, Hydro-Québec may base the reference power on the normal consumption profile without photosynthetic lighting.
On the basis of load management requirements and power system availability, Hydro-Québec reserves the right to prohibit consumption of additional electricity on 2 hours’ notice.
Hydro-Québec will notify you of the price of additional electricity 7 business days before the beginning of each calendar month. This price will remain fixed for the entire monthly period.
Calculation of billing amount
Energy billed as additional electricity is calculated in 15-minute blocks.
- Consumption that exceeds the reference power is billed at the applicable price for additional electricity.
- The reference power and the rest of the energy are billed at Rate DP, M or G-9 prices and conditions in effect.
