Off-peak charging vital for electric car power supply, experts say. UK energy system can cope with rise of battery-powered vehicles if 4-6pm slot avoided, says report. The number of battery-powered cars on Britain’s roads will grow from around 120,000 today to 10m by 2035 and pass the 17m mark five years later, predicted Aurora Energy Research. If those millions of drivers return home from work and charge their cars immediately during the peak hours of 4-6pm, that would add around 3GW, the equivalent capacity of the Hinkley Point C nuclear power station, to peak power demand. The report said the alternative to that “dumb” scenario is “smart” charging, where car owners are encouraged to use cheaper tariffs at off-peak times or relinquish control of their charging to an energy firm. That scenario would add just 0.5GW of peak demand.
