Who runs the network in South West England
The wires in this region (Bristol, Somerset, Devon and Cornwall) are operated by National Grid Electricity Distribution. Network costs are set per region and passed through to every electricity tariff — they are the main reason the same kWh costs a different amount here than elsewhere in Great Britain, and why the Ofgem price cap itself is set regionally.
