The UK electricity market, regulated by Ofgem, is split into four phases: Generation, Transmission, Distribution and Supply. The Distribution system connects the transmission system to the consumers within a region. IDNOs are networks embedded within the distribution system that own the ‘final mile’ of cable within a new development.
Typically, all new property developments will require a new electricity distribution network and those networks are installed by a qualified Independent Connection Providers (ICP) accredited to the Lloyds Register National Electricity Registration Scheme (NERS). As an Ofgem regulated Independent Distribution Network Operator (IDNO) EA Networks adopts, operates and maintains new electricity distribution assets installed by ICPs after agreeing the value of the assets.
