The DSO (Distribution System Operator) or DNO (Distribution Network Operator) is the entity responsible for the management, operation, and maintenance of the local electricity distribution network. Its primary function is to distribute electricity from substations to end-consumers, including homes, businesses, and EV charging stations.
The DSO ensures network upkeep, the integration of new installations, and the management of faults or disruptions. It also plays a crucial role in the energy transition by facilitating the integration of renewable energy and managing grid load.
In Canada, this function is carried out by various provincial and municipal utility companies, such as Hydro-Québec, BC Hydro, Ontario Power Generation, and others, depending on the specific region.
