It is important to mention that there is no precise temperature or rule of thumb to dictate whether there should or should not be an interruption. Depending on the duration of cold days and when the winter period starts and ends, storage provisioning tools might no longer be able to operate at their full capacity. This means that, even when the weather turns milder, it may be necessary to plan a day’s interruption, or to continue an interruption already in place.
If, even after the interruption, the demand for continuous service was not completely satisfied, Gaz Métro would then use the last tool available, that is, withdrawals from its Liquefaction, Storage and Regasification (LSR) plant, set up to ensure continuous distribution service.
The choice of customers subjected to a service interruption is based on the rate structures, as mentioned in the Conditions of Service and Tariff, and not according to the zone or region where a customer is located.
Remember that interruptible service customers benefit from lower load balancing and distribution rates than customers at the general rate of continuous service; in return, they may be subject to interruption on peak days.
