Starting from 2013 with the opening of the electricity market, customers have two separate service providers: a network operator and an electricity seller. The network operator is the network operator in the area where you consume electricity, whose task is to supply electricity to your home, collect consumption data, and maintain the lines and other network-related equipment. The network operator forwards the invoice for the transmission of electricity - or the so-called network connection. The electricity seller is your electricity supplier to whom you pay for the electricity consumed.
