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 role is to distribute electricity from substations to final consumers, whether they are homes, businesses, or EV charging points. The DSO ensures network maintenance, the integration of new installations, and the management of faults or disturbances. It also plays a key role in the energy transition by facilitating the integration of renewable energy and managing load on the network.
In the UK, this function is carried out by companies such as UK Power Networks, Western Power Distribution, and SP Energy Networks depending on the area.
