Whatever the rate of your electricity service contract, you can have an electricity generating installation, like a solar panel, that allows you to reduce your electricity consumption and bill. However, if your contract is with Rate DT, you cannot use the net metering rate option, offered by Hydro-Québec to self-generators.
The net metering option is available for customers who have Rate D and Rate DM. It allows you to feed your surplus power into the Hydro-Québec grid in exchange for kilowatthour credits. This credit is applied to your bill. If the power you generate is not enough to meet your needs, you can draw power from the Hydro-Québec grid and enjoy reliable, high-quality service.
