A Distribution System Operator (DSO), is responsible for operating and maintaining the electric power distribution system. This system delivers electricity from the high-voltage transmission grid to end users, including households, businesses, and other consumers. DSOs operate at the lower voltage levels and focus on the final stage of electricity distribution to end users within specific local areas or regions.
In many countries, there are multiple DNOs/DSOs operating at a local level, serving different geographic areas. This local structure allows for more localized management, efficient operation, and effective coordination with the transmission system operator to ensure a reliable and balanced electricity supply to consumers.
