The trope has it that soon we’ll all be auto-piloted by EVs charged by electrons lovingly caressed from sunshine and breezes. Although, if that vision is ever realised, expect to hear more about collisions between stray unicorns and EVs, which is just as likely as an RE-powered all-EV future.
Meanwhile, back on Earth, grid managers have worked out that the potential load represented by having hundreds of thousands of all-EVs sucking power from the grid while they’re recharging threatens to send the grid into meltdown, on a routine basis.
Naturally, there’s no solar power available during the night-time EV charging routine and less still, where that routine coincides with a burst of calm weather.
It’s a dilemma, to be sure, as Paul Homewood reports.
UK: E-car chargers will turn off to prevent blackouts
Watts Up With That?
13 September 2021
From The Times:
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.
The government is also taking powers to impose a “randomised delay” of up to 30 minutes at other times to avoid pressure on the grid if there is a scramble among motorists to recharge their batteries at the same time.
There are only 300,000 battery electric vehicles (EVs) on the UK’s roads.
We have long been assured that EVs would not cause problems for the grid, because most of the charging would take place at night when there is spare capacity. As many of us could have told them, most drivers would simply plug in as soon as they got home.
Now the government has woken up to this reality.
Charging between 10pm and 8am may be OK for some, but what about shift workers?
This new regulation is a clear admission that government is now seriously concerned about grid capacity and blackouts. I suspect there will be many more measures to come designed to ration electricity.
Watts Up With That?
