Connecting solar to the Chafford Hundred, West Thurrock and Purfleet-on-Thames network
The distribution network operator (DNO) for Chafford Hundred, West Thurrock and Purfleet-on-Thames is UK Power Networks, which runs the East England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
A bigger inverter or battery output needs a G99 application in advance. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator.
