5. UK renewables growth Data from BEIS, Energy Trends.
Peak demand of the order of 60GW
Falls below 40GW on a summer day
1m EVs with 7kW chargers would make a huge contribution, 5m would balance everything
Data from BEIS, Energy Trends.

6. Supply / demand match 2016 electricity demand 2016 solar generation
2016 wind generation

7. Average Ev charging profile at single household
Non-EV use based on Elexon class 1 profile
EV charging data c/o DriveElectric from WPD’s Electric Nation trial

8. Some challenges Is the network big enough?
Do we have enough power stations?
Do we have enough fuel for the power stations?
Will user demands (or institutional blockers) limit potential?
Can a uniform customer experience co-exist with niche business models?
(Network size) Yes, but cables are not a good way to move energy quickly!
(Power stations) Yes, but not quite the right question

9. Some actions Require control from subsidised chargers
Improve access to time varying pricing for discretionary charging
Acclimatisation to real costs for on-demand charging
