Economy 7 does not scale as more people shift to charging overnight.

Did you not read the post?

Grid controlled chargers will allow us to charge as many cars as possible over night. If you can sell cheap centrally controlled electricity for car chargers we can accommodate a third of generation capacity (the drop overnight) for electric cars.

No it won't solve all the supply issues but it gives us breathing room while we formulate a strategy and improve batteries.

My suggestion would be convert expensive vehicles (Trucks/Buses) to Hydrogen and build a distribution infrastructure that cars can use later.

Offer Hydrogen conversion to classic and even popular cars when infrastructure improves ~ 60% of cars are over 6 years old.

Promote Hydrogen fuel cell cars.

Switch off petrol & Diesel gradually as Hydrogen/Electric become more common.

Remove rare elements from batteries as soon as possible and offer battery cars in parallel as we improve the national grid & generation.

Or we can just let the substations burn!

No, your posts are often too long.

In Germany I have solar & a Powerwall. This works very well.

Perhaps you are underestimating how long it takes to spin up a power station or wind farm to demand. Hell even the tea break during Coronation street is a pretty major & precision exercise.

Electricity flows across the grid, it is not routed like IP traffic making demand adjustments at a micro level very tricky.

Try to keep it short for you.

Solar & powerwall is a £10-20k investment. Most houses won't spend that. £500 for a charger is about the limit.

If you can control the demand locally by using smart meters predicting demand is easy. With my idea when you have excess you can first charge emergency storage e.g. water /Hydrogen storage then dump to charging cars, when you are short you can cut off the cars, if you are really clever you can use the cars as storage.

Plenty of heavy electric users have been doing something similar for years.

Recent implementations by people like Moixa are showing the way.

Fair enough on the solar investment.

You can predict/control electricity demand as much as you want, the problem is infrastructure delivers electricity, not software. Moixa focus their EV plans on B2B. B2C use patterns of cars outside of commutes is a completely different beast.

People are going to have to shell out another £10K soon or get used to living in a cold house.

Cut meat and dairy by a FIFTH to save planet: Report tells Brits to slash car trips and curb flights | Daily Mail Online

A dramatic report from the government's Climate Change Committee laid out a swathe of measures to slash emissions over the next 15 years.

It urged moves including halting sales of gas boilers by 2033, banning new fossil-fuelled cars – including hybrids – by 2032, and encouraging people to cut the amount of meat and dairy they eat by a fifth in the next decade.

The plan is part of a push for UK to meet a target of getting emissions down 78 per cent by 2035 compared to 1990 levels.

It represents a major increase in ambition in UK climate efforts, with the new 2035 target almost as tough as the previous long term goal of 80 per cent cuts by 2050, which was in place before the net zero law was passed in June 2019.

However, the report from the advisory body suggests that energy efficiency measures could cost £10,000 per home.

If you have control of the demand tap at each endpoint via a smart meter & charger then yes you can adjust load. If we don't we will be switching off the grid in places so everyone can charge their Teslas.

Commuter vehicle charging loads tend to be during the night when use of electricity falls 30% the grid has excess capacity.

It is not going to fix everything but its a start.

Good grief, you can control "load" by regulating demand but supply is the issue. B2B is more predictable than B2C. You can predict what time the garbage truck or bus runs. Plug-in EV user charging behavior has a significant influence on a distribution network and its reliability and tulip loads of money is being poured into machine learning to try & address this.

Commuter vehicle traffic has completely changed due to Covid, there are no models yet.

Crapita run the smart meter programme, and the meters can't even cope with a change of supplier. You're asking a lot here...

Currently car usage is down massively so its a good time to start. I may not plan to use my car every day so the charge window can be longer.

When and if we return to normal then the commuter vehicle charging load will probably be between start 6-8pm and say finish at 6-8am (to be decided properly by research but that covers most of my commutes over the last 3 decades.)

I come in and plug my car in at 6pm and the intelligent charger App says you can pay 10p a unit and have 4 hours charge by 8am (I set the charge window end) on random charge in this charge window , or you can pay 18p a unit and have 4 hours charge by 10pm i.e. immediately. I choose and the rest is controlled by computers. If there is not enough free capacity at the start of the charge window the price changes and I may not be able to choose continuous charging. I may not always get a full charge if I don't pay the premium or if capacity isn't there.

We have a 33% drop in demand overnight so we have some slack but we won't have enough for everyone to own an electric car without significant investment, hence my support for Hydrogen.

If we can manage a third of the demand on the grid for charging overnight EVs by setting the prices so consumer behaviour is modified is that not a good thing? Remember most houses have a 100a fuse and so can draw 23,000W or 3 times a normal car charger but we could control a third of that.

lots of ducks to line up. The alternative is burning substations and electric cars becoming expensive drive ornaments.
