What this could mean for UK Power Networks
• By 2020:
– We will be supporting as many new connections of EV
charge posts annually as we do bus-shelters and lamp
posts today
– have seen PV added at the domestic level to up to 15%
of our maximum demand
• By 2023, 1 in 25 of our ‘customers’ will be an EV charge
post!
• Regulator has shown clear direction towards ‘Smart’
• We want to serve customers better
• Low Carbon London is the idea platform to prepare for
this future
