I know a few people in the energy generation industry. There won’t be power cuts, stop reading click bait on the daily mail.

Such blatant and desperate trolling rofl

Yea... us EV idiots feel pretty stupid now... we're gutted we're not paying nearly £2 per litre of fuel like all the cool kids smile

The sensible answer to the daft question is that it wouldn't affect the vast majority of EV owners. The blackouts would be temporary and dead easy to charge in between them.

Turn off the Daily Fail presses and web servers first, then you need do nothing else.

Back when you could use red diesel in a generator, it was actually cheaper to charge an EV than using the mains in some cases (business rates so not capped like domestic).

So millions are warned that we may have power cuts this winter because of energy shortages, potentially a failure of our government on a criminal level, My suggestion is - should we cut off EV charging points first, so that the available electricity can be better prioritised? No doubt it will upset the smug, preachy early adopters of a technology that is unfit for purpose, and which is never likely to be the solution. I also wonder whether extended energy shortages could mean a reprieve for the ridiculous plans to ban ICE engine production from 2030.
I have not used a public charger, or a petrol station in the last 10,000 miles.

A smug EV bd.

PS. The ban is coming and there is diddly squat you can do about it. Time to roll over and take it like a man laugh

Anyone who expects the bans to not happen or be delayed is dreaming. Or at least, desperate and clutching at straws.

They've already bought the date of the ban forward 5 years from the original date - so I'd say they're pretty keen on it happening. The main manufacturers are all on track with their EV range rollouts too.

There is, or a least was, a diesel generator 'farm' just outside Plymouth.

I've worked on industrial sites where they fire up their diesel generator at certain times of day to save cash.
That was big old diesels, maybe running on something other than red DERV type 'gas oil'.

Short Term Operating Reserve (STOR) farms are still pretty common. Usually diesel generators or simple gas turbine farms.

I think some of you have sort of sussed me out. It is a genuine news story and someone may have to make decisions about prioritising energy usage (which can be done in many ways). It wasn't trolling ( there can be a nasty side to that), but possibly at the back of my mind it may have been a gentle wind up of the EV brigade
It's already been said, it's clear that you've never been near to an EV in any shape or form.
Cars are stationary over 95% of the time. The average driver in the uk needs to charge about 2h/day.

Putting thoughts like this online reminds me of the saying "Better to remain silent and be thought a fool than to speak and to remove all doubt.". rofl

Shutting off slow domestic chargers to deal with short-term load surges on the grid sounds like a good idea to me. I suspect it'll happy voluntarily in practice as more and more EV owners shift onto tariffs which follow the wholesale price of electricity and set a maximum they're willing to pay. Of course if V2G really takes off, EV owners will even be paid to feed power back into the grid at peak times which is a win-win solution to load management.

I'd certainly sign up to that if I had an EV, sounds like a great idea and will make EVs even cheaper to run compared to ICE vehicles. smile

I already does happen voluntarily.

Octopus energy are running several schemes.

One is 1 hour free electricity a month, during daytime. There's nothing more to it, 24 hours notice and you get free electricity.

The other is encouraging you to use as little energy as possible and paying you the difference based on a "normal" day consumption.

It all adds up to pennys at this time.

Interesting to see those "peaks". I think that the gap between 11 and 16h is because of solar?
Those chargers are ideal for load balancing though.

I think what we will actually see regards grid balancing and solar will be far more advanced than set times when you should or should not charge.

In theory, if even a small % of all EV's were generally plugged in whilst parked, a centralised system could start them charging in sync with times at which their is excess energy feeding into the grid - or at least ping the owner to let them know that they will receive a small discount if they do start charging then..

Currently Tesla have built a few battery plants to help balance the grid and smooth out renewable energy input. But it wouldn't take much to utilise the millions of EV's around the globe to achieve the same, everywhere, in real time. We have the technology - it's just a matter of BEV itself maturing to a point there is more standardisation and regulation introduced to ensure all future EV's have the capability to have their charging controlled by a central smart system.

Agreed, iirc Hyundai is doing pilot projects in Utrecht in that sense.
Seeing EV's as the solution rather than the problem is a great way to look at it.

The article is deliberately misleading.

There's nothing in the provision that says they "will not operate". It's that be default they will not automatically charge when plugged in at that time.

The random 30 min delay for overnight charging is useful. At the moment the grid sees a frequency drop at 0030h when all the chargers lock-in.

Since I typed this out for the other thread that the mods think this matches, I may as well post it.

https://www.pistonheads.com/gassing/topic.asp?h=0&...

The perfect is the enemy of the good.

Current real-time carbon intensity of the network;

https://electricityinfo.org/real-time-british-elec...

Over the last 24 hours it has been 313g/kWh. Over last year, it averaged 232g/kWh.

Burning a gallon of petrol releases 10.87kg of CO2. A gallon of diesel, 11.91kg

10.87kg / 313g is 34.7. That's how many kWh is equivalent to a gallon of petrol in CO2 emissions at this currently high level of grid emissions.

For diesel, it's 38kWh.

EV efficiency stats said:
Here are the top 10 most efficient electric cars to lease in terms of miles per kWh:

Tesla Model 3, Standard Range Plus: 4.56 miles per kWh
Fiat 500e: 4.54 miles per kWh
Tesla Model 3, Long Range: 4.54 miles per kWh
Hyundai Ioniq Electric: 4.19 miles per kWh
BMW i3: 4.16 miles per kWh
Mini Electric: 4.10 miles per kWh
Seat Mii electric: 4.10 miles per kWh
Volkswagen e-up!: 4.07 miles per kWh
Smart EQ fortwo: 4.05 miles per kWh
Hyundai Kona Electric (39 kWh): 3.99 miles per kWh
Miles per kWh figures are approximate and will vary according to ambient temperature, speed and other factors. The efficiency data are based on estimates of average, real-world range (roughly official WLTP range minus 18%) and useable battery capacity.

https://www.selectcarleasing.co.uk/hybrid-electric...
If we said 4 miles per kWh, even on this day of poor grid carbon efficiency, we'd be getting 139 miles out of the same amount of carbon emissions as a gallon of petrol. Or 152 miles out of the equivalent of a gallon of diesel.

Does your petrol car do 139 miles to the gallon? Does your diesel do 152 miles per gallon?
