what is dno

DNO stands for Distribution Network Operator, which is a licensed company responsible for the maintenance and operation of infrastructure that delivers electricity from the national transmission network to consumers in the UK. DNOs own and operate the network of cables, transformers, and towers that bring electricity from the national transmission network to businesses and homes. They are responsible for the distribution of electricity from the transmission grid for a large geographical area, and they manage distribution networks from 240V to 400 kV through underground and overhead power lines, covering commercial, industrial, and residential properties. DNOs are regulated by Ofgem to protect consumers from overcharging, and they must connect customers when requested. There are 14 licensed DNOs owned by six different groups that cover specific geographically defined regions of Britain.
