The essence is here:
Electric car charging points in people’s homes will be preset to switch off for nine hours each weekday at times of peak demand because ministers fear blackouts on the National Grid.
Under regulations that will come into force in May, new chargers in the home and workplace will be automatically set not to function from 8am to 11am and 4pm to 10pm. Public chargers and rapid chargers, on motorways and A-roads, will be exempt.
Owners will be able to override the preset times, to take account of night workers and people who have different schedules.
The Commons Transport Select Committee called this summer for owners to be incentivised to recharge batteries ‘little but often’ to avoid power shortages.
Electric cars have been forecast to create extra 18GW demand for power in UK at peak times by 2050, according to the National Grid. That is the equivalent of six Hinkley Point nuclear power stations.
