About us

As a Distribution Network Operator (DNO), our role in the energy system is to carry electricity from the high voltage transmission grid to industrial, commercial and domestic users via a network of cables and poles.

Although your electricity is sold to you by your electricity supplier, it’s carried along wires and poles by us, your electricity network operator. Our electricity distribution networks carry electricity to over 3.8 million homes and businesses across the north of Scotland and central southern England.



As a regional monopoly, funded through electricity bills, we are regulated by the Office for Gas and Electricity Markets (Ofgem). Ofgem regulates network operators through periodic price controls that determine the revenue that can we can earn, and that stipulate levels of performance. 


RIIO-ED2 is the next electricity distribution price control period set by our regulator Ofgem. RIIO-ED2 will run from 2023-2028. We’re currently building our business plan to submit to Ofgem, which will set out how we intend to operate and develop our networks during this period and are actively seeking views from our customers and stakeholders to help shape our plans.
