How much spare capacity does the National Grid have?


The UK is scrambling to ensure its energy security for the coming winter after the National Grid revealed a spare capacity of just 1.2 per cent, the worst in a decad



i think we should show ppl what will happen and just shut down coal and gas power stations for a month and see what happens.

every one would kill them self with no facefook twatter and the internet will be like the end of the world. :p


Electricity demand increased in 2021 to 334.2 TWh, up by 1.2 per cent from 2020. The increase was primarily a result of the response to the Covid-19 pandemic, which severely restricted the activity of business and industry in 2020 but had a smaller effect in 2021. Demand increased in all sectors in 2021 compared to 2020. The reduction of restrictions in response to Covid-19 led to an increase in industrial and commercial electricity consumption, whilst cooler temperatures increased domestic consumption. Electricity supply increased in 2021, due to higher demand for electricity, but UK generation fell with higher supply from net imports. Total electricity supplied in 2021 was 333.2 TWh, with net imports of 24.6 TWh, 7.4 per cent of electricity supplied. Electricity generation fell to a record low of 308.7 TWh in 2021, 1.2 per cent less than in 2020. Generation from renewable sources decreased 9.3 per cent to 122.2 TWh in 2021. This was driven by less favourable weather conditions for wind, hydro and solar generation. In particular, wind generation dropped to 64.7 TWh in 2021, down 14 per cent despite increased capacity. This was because of unusually low average wind speeds across most of 2021. Fossil fuel generation increased 11.0 per cent in 2021 to 131.4 TWh. Increased demand for electricity and lower renewable generation increased the need for fossil fuel generation. The proportion of electricity generation coming from renewable sources fell in 2021 but was still the second highest share on the published data series. The renewable share was 39.6 per cent, down by 3.6 percentage points compared to 2020, lower than the share of generation from fossil fuels (42.6 per cent), a contrast to the previous year. Decreased nuclear and renewable electricity generation meant the share of generation from low carbon sources was 54.5 per cent in 2021, down from 59.3 per cent in 2020. Total net imports were a record 24.6 TWh in 2021. Total imports were 28.7 TWh in 2021, up 28.4 per cent compared to 2020, while total exports were down 7.0 per cent on 2020 to 4.2 TWh. Interconnector capacity rose to 7.4 GW in 2021 with new operational cables between the UK and Norway (North Sea Link), and a second link to France (IFA 2). Total de-rated generation capacity rose to 76.6 GW in 2021, a 1.0 per cent increase on the 75.9 GW capacity in 2020. Capacity for renewable technologies increasing by 3.2 per cent to 23.2 GW while fossil fuel capacity remained unchanged at 42.5 GW and nuclear capacity unchanged at 8.1GW.

It's naive to the extreme to think that somehow we can ditch all our gas boilers, ICE engines, (including stuff never mentioned like diesel electric trains, lawn mowers, chain saws, etc etc) and our current generating system will cope. It's struggling now.
30 million plus cars on UK roads. Imagine drain on grid with each of those taking 40 or so kwh out of system daily.

Overnight charging - I wish.
Like many households, mine is a terraced house with no parking and is on a 2 lane A road. True, very quiet at night as it's rural but still impractical to park outside.
The village is around 3/4 of a mile long, it has six lamposts, the nearest being 150yards away on someone elses frontage.

In the rural setting most journies are longer than the average urban, still not great, granted, and mostly more fuel efficient as there's little traffic and no traffic lights. However the projected range on that, no doubt very expensive, VW van would give me 2.5 trips to my workshop. Current diesel on full tank would conservatively give me 30 trips.
The amount of logistic planning that VW guy was having to do was insane. This on top of whatever he was carrying in his head about the job in hand. I'm an electrician and know some of the complexities one has to deal with, having extra head space on, 'How am I getting home tonight' is not good.
I am firmly in the second hand van market, my current Boxer is the most expensive vehicle I have ever bought at £7k. E.V. vans are way out of my budget.
Don't get me wrong. I know we need to change our power usage profile, especially for transport. I've been banging on about it since the 70's. I even considered buying an old milk float and putting a generator on the deck as I lived in an urban setting at the time.
I really hoped that e vehicles were going to be an answer but, so far, they are certainly no silver bullet. I suspect that plug in E.V.'s may prove to be the Betamax of the car world when another technology is developed.
How about a vehicle whose motive power is fully E.V. (electric motor with no gearbox so lighter/simpler transmission)but carrying a small ice powered generator with plug in as an option. This could be petrol or hydrogen powered (JCB are currently developing these engines). Battery range would be around 100 miles but with the generator auto start on registered battery capacity. Most urban driving would be emissions free but without the complicated logistic calculations for trade and commercial drivers.

Why aren't your brains functioning?

Soundwave:
The answer to your question is that almost all of the national grid capacity is spare between midnight and 4am every day. Then the current is on offer very cheaply to get rid of it. E-cars have charge timers, my typical one has two of them. The owners arent dumb enough to pay the high prices when they can charge then cheaply, so that is what they do,

Zlatan:
The average annual mileage of all our UK cars is 7300, some 20 miles a day, Even if all of them suddenly magically became e-cars, they couldn't possibly use 40kW each in the same 24 hours. They would at most use 8kW average each, one fifth of your contention.

Their chargers would replace that one fifth in an average of two hours of that four hour window of plentiful availability.

Of course that is a big drain, BUT WE HAVEN'T GOT 30 MILLION E-CARS AND WON'T HAVE FOR AT LEAST 15 YEARS YET.

By then in 15 years time we will have Hinckley Point and Sizewell C up and running, plus many hundreds more wind turbines generating, creating even greater surplus in that middle of the night window for charging.

You are absolutely right that it will not be enough for all home heating systems and I also foresee very big problems in the other 20 hours of each day. But that will not affect the great majority of e-car drivers for whom the night window is more than adequate.

It will be the minority of drivers who do long distance driving needing to charge during trips who could well hit big problems if current isn't available.

However, that is being tackled. The new en-route charging stations are increasingly having solar panel banks and battery banks included, some even renting large fields alongside covered with panels. So by when most cars are e-powered in 15 to 20 years, the long distance minority problem could well be solved.

In any case as you may have noticed from my posts, I'm absolutely certain that far fewer people will own cars by then. High costs and alternatives will drive change. Just as today would be unrecognisable to those from the past, so tomorrow would be unrecognisable to us if still alive in 20 or more years time.

This is what happens to people like yourself who haven't followed the subject and frankly know far too little about it. So you reinvent the wheel.

We've already had these, they were the original hybrids and they have failed and all been discontinued. For example

The Chevrolet Volt
The Vauxhall Ampera
The original BYD
The BMW 13 hybrid

I won't waste time in the complex explanations of why they failed, that they did and were proved unnecessary anyway is all that matters.

This second answer is to this part of your post:

It will take at least 15 to 20 years to replace all the 32.7 million cars we have. 15 to 20 years to solve your common problem, so during that time it will be all those who can have home charging who will be predominately the e-car users. That is already the case, 84% of all today's e-car users have a home fast charger and a number of the remainder have charge points at their place of work, effectively the same thing.

And your problem is being dealt with slowly. Schemes are up and running to provide charging in such locations, for one example some villages in Kent are being provided for. But only where a need is already in prospect of course. Street chargers dont need lamp posts, they are used when they are convenient, but when not, bollard chargers are provided.

For busier pavement areas where street furniture can be a nuisance, one firm provides sunken bollard chargers flush with the pavement. A smartphone app makes the charger rise for use.

There's more I could mention, but this is enough to show that there's far more going on than you realise.

Flecc, your solution is accept EVs but stay at home. Not a real solution.
You keep quoting averages. As tho that means most driving can find an EV solution. If you knew more about the maths behind averages you, d realise making a solution to fit average won't work for the majority.
The average size foot is probably a size 8 . Just make size 8's and see how many folk wear shoes. Mean average is almost useless without further info.. Standard deviations, inter percentile ranges, standard distribution curves etc etc need to be examined to see what exactly is going on.
I am telling you as a fact a vehicle with 160 mile range, irrespective of public charging points would be bordering on useless for my travel profile. Chap above has explained similar but you insist we are wrong. That is at best pretentious of you. I know which vehicles would work for me and which would not. At moment there simply is no alternative to my 2 litre diesel car and 3 litre diesel camper van. Almost at any price. Working for you or some meaningless average driver is irrelevant to my position. Saying my stand is through some prejudice against EV is utterly ridiculous. I built a fully electric Westfield /Caterham 7 ( actually an MK) 15 years ago. (, Siemens motor/control etc) It was fantastic. For 80 miles. (to be fair I was involved with it, doing majority of mechanical side, it was a demo car for a firm I did work for) Nothing has really changed since then. I, ll be sticking with Jag for as long as possible or until a guaranteed range of 250 miles at sub £20k purchase price becomes available. (Jag cost £15k,4 years ago. Easily achieves 60 mpg, great to drive, 600 mile range, £30 a year to tax and still worth £12k)
Please please, suggest an EV alternative and I, ll have a look.
I,m writing this from daughter's House. 80 mile journey. (About 70 mins via motorway) I, d have to be thinking about where /if/how long to recharge on way home. Even in the 42k C4 mentioned earlier. I ain't putting £42k into a Citroen C4. No chance. One, I can't afford it. Secondly I don't want hassle of 153 mile range. Thanks but no thanks.

is this why our electric is so cheap then and why we blew up the Russian gas pipe line to import gas from the usa pmsl.

ev will solve nothing and just make them even more money have total control over it and where you go and how fast and how long it will last.

and dont forget electric smart meters that will monitor usage 48 times every 24 hrs so there will be no cheap time to use anything if you have one of those things.

again just to make them even more money and keep you in debt like good little slaves to the system.

You are starting to sound like you are on a crusade Flecc.
I think you need to do some maths about night time spare capicity against let's say 15 million EVs taking 30kwh every night and half country on electric heating. Not to mention the fact that night time charging doesn't get everybody home. How many topping up to to help that 160 mile range at tea time. The logistics simply do not work for mass take up of EVs. Yes, fine whilst those that can manage on 160 miles between fill ups do so. (not sure what %age EVs are at moment but it's at most 5%,)
Have a look how many EV owners would rather go back to ICE next time? (survey I read was 40%)
And spending £42k on Citroen C4 is much more akin to keeping us slaves to the economy than running the ICE we have into ground. (and I suspect latter better for environment)

Oh dear, shows how little you know. Some of the companies are now linking low cost periods to the smart meters to allow MORE time for low cost charging, not less.

pre pay smart meters are the most expensive way to pay for electric and why if you are in debt to them they force install them to keep you in debt.

but you wont know this fact unless you have used one and why they are forcing them to be installed again all for more money.

Doh!!

Stop trying to teach granny to suck eggs. Of course I know that there are many users like yourself who e-cars just don't suit.

But until we get to replacing more than half of our car fleet, there are huge numbers for whom they are perfectly ok, so it is they who are taking them up, and they are the great majority.

The problems will therefore only possibly arise many years from today. Meanwhile for the next 8 years you and those like you can carry on buying pure ic cars for the next 8 years, or for the next 13 years hybrid-ic cars instead.

Since our UK average car life is 23 years, there is no problem for 36 years yet (13 plus 23 years), so stop trying to tell me there is an impending one.

Yes, there is an e-car and battery cost problem, but as I've said, that isn't a problem when the take up will be so slow at under 5% of the fleet replaced each year,

After a long while we will certainly run out of those who can afford to own and run one, but they will use the alternatives as the world changes, resulting in far less car ownership. Soundwave at least recognises that.

That wont suit you in 36 years time, but so what? The future isn't yours or mine, it belongs to those who follow us.

I don't use then and dont have to. Most suppliers do not force their use and those who do only do it to the bad payers. That is th customers fault, not the supplier's.

if you are in debt they will force install them and can see many more getting installed in the years to come.

even if you dont put money in to it the standing charge still goes up even if you have no power so a complete rip off.

Then don't get into debt.

The standing charge increases are not a rip off by our supply companies, they dont receive a penny of them.

Fair point.
And, no, I, m not suggesting EVs don't suit some and I, m not in slightest against their growth.
What I am saying is 3 things.
Our generating capacity needs to grow alongside EV take up. Night time spare capacity I, m afraid simply does not cover any type of significant increase in EV usage along side higher home use as many convert to e heating.
Secondly the whole charging infrastructure needs massive investment and growth. (I, ve already seen problems, agreed some initial teething but some simply logistic issues. (somebody left car charging, with 2 cars awaiting same point, returned after 25 mins, to realise car wasn't charging, sorted problem and went for another coffee, the 2 cars waiting were unimpressed but had no choice but to wait, one of drivers waiting was telling story to anyone nearby)
Thirdly.. Range needs to improve.Which, I suspect will never happen. Think ICE will see my driving days out.
Thinking of changing van and Jag to a single vehicle. Some 7 seater. S max, Discovery,?? etc.
Must be capable of 50 mpg. Launch and recover boat. Room for windsurf kit inside.
Carry 7 occasionally. Sub £20k. If an EV qualified I, d try one.

I disagree, since the generation and therefore spare night capacity is growing faster than the e-car takeup and electric home heating takeup. There will be some evenness, but as the war in Ukraine is halted in a year or so time and more wind farms come on stream, that will settle. Later Hinckley Point coming on stream will greatly increase night spare capacity.

Secondly the whole charging infrastructure needs massive investment and growth.
It's already getting it, far faster than e-car takeup. The routes most drive on are already more than covered enough, That was true even on my run from London to the wilds of Dorset in 2018 and since then the numbers of rapid and ultra-rapid chargers on that route have increased still further, far in excess of what I could possibly need. But patience is necessary. Just as adequate roads followed vehicles, so enough charge points at all times will follow sufficient e-vehicles to justify them.

Thirdly.. Range needs to improve.Which, I suspect will never happen. Think ICE will see my driving days out.

Fully agreed, these won't happen, certainly not for the masses. It will be a changed world, but as ever those born into it will like it and fight against their threatened changes. Small c conservatism, thus it ever was.
