We've had several power outages in our area recently, most of them JUST long enough that the food in our fridge was deemed unsafe and we had to toss some of it out.

This sort of thing really makes me think about the large scale deployment of rooftop solar and batteries. If we had a battery system in our house, we could have used it to intermittently cool the fridge/freezer and potentially save the food and avoid the waste. It seems to make more sense to have everyone have their own power generation capabilities than for all of us to rely solely on a broad network stretched thin.

I know very little about this subject, but the primary reason we haven't done it is that there aren't many subsidies around where we are. In addition, I often wonder about the future proofing on these systems. Our old house had coax run to every room because they just assumed you would be using cable tv instead of wireless streaming.

The reliability of the UK grid was 99.999998% in the past year.

The last time I can recall any long electricity cuts was during the 3 day week in the early 1970s... Which perhaps explains some of the reasons why coal power (or at least the people who produced the coal) were seen as a political threat:

https://en.wikipedia.org/wiki/Three-Day_Week

NB I wasn't very old at the time and rather enjoyed the experience!

cameronh90 · a year ago
I'm in London, and I've only experienced two power outages in the last decade, each lasting less than a minute.

We have our problems, but electrical grid reliability is definitely not one of them.

prennert · a year ago
That does not mean that day long power outages are impossible. Especially not locally.

For example, storm Arwen in 2022 left lots of communities without power for many days https://www.ofgem.gov.uk/publications/storm-arwen-report . Admittedly not because of power generation, but because of transmission lines being cut by falling trees.

Exactly, the reliability of home brew battery systems is likely to be quite a bit less.

"In our area recently" — at least state the country!

You are commenting as if your experience is relevant to this news from Britain, but weasel out of even the roughest location. Your phrasing and choice of words is generally American.

thepuppet33r · a year ago
Guilty as charged! American, unfortunately located in the southeast.

To be clear, this wasn't intended as a comment against or argument against the UK's accomplishment. I am EXTREMELY glad to hear they're moving away from coal.

lars_francke · a year ago
A battery alone is not enough. You also need an inverter that's capable of powering your house. Most are not.

They need to e.g. provide the proper frequency on their own and entirely/physically decouple from the grid etc.

They are available but just rooftop solar and a battery is not enough.

It depends on how much you want to run. Just keeping the fridge working and powering an internet router and a tv would go a long way and wouldn’t take much.
outofmyshed · a year ago
Commodity hybrid PV inverters are now very capable of offgrid/island mode - I have one. If the grid goes down (which it does - I live rurally) I can flip a changeover switch and power my whole house from PV or battery up to a limit of 5kW, which is plenty to keep everything necessary running.

It’s not a mainstream feature and there’s a high setup cost but the tech is readily available and the price/kWh of home batteries is going down steadily.

bArray · a year ago
I think the easiest solution here would be one of many readily available UPS's. If the fridge/freezer is kept shut, it should just sip at the power.
magicalhippo · a year ago
Just need a BEV with inverter, which many modern cars have, and a long extension cord.
therealdrag0 · a year ago
This. Seeing a lot of great stories of EVs being very useful in the aftermath of hurricane Helen in US. The Ioniq 5 can power a house for 5 days for example. And is more cost effective (since you also use it as a car) than installing batteries at home. (Disclaimer not all EVs support V2L)
00deadbeef · a year ago
Where? I'm in the UK. One of my network switches has 595 days of uptime so I haven't had power issues in at least that long, but it seems like more than 3 years since the last disruption when something blew at the substation round the corner and was fixed within minutes.

> they just assumed you would be using cable tv

I think you mean - they just assumed you would be connecting to the antenna on the roof to get the 4 glorious full colour channels.

gandalfian · a year ago
Then there is Drax a vast coal plant now burning wood chips cut from foreign forests, dried and shipped across the ocean in bunker oil fueled cargo ships. That counts as renewables. 7% of our electricity today, more than solar. I am actually very optimistic about the future in ten years of so. I think we oversell the present a bit though.
ZeroGravitas · a year ago
Drax is less than 4% of electricity now, it's been steadily dropping:

https://ember-climate.org/insights/in-brief/the-largest-emit...

So lower than solar now (which has been growing).

mhandley · a year ago
I'm not a fan of Drax (is anyone?), but I guess the alternative is worse, at least for now. In the short term, the marginal alternative is LNG, also shipped in oil-fueled cargo ships. So as we continue to build out wind and solar and reduce the amount of natural gas we burn, it's probably good to keep Drax on biomass. But it shouldn't be a long term solution.
newpavlov · a year ago
>the marginal alternative is LNG, also shipped in oil-fueled cargo ships

LNG ships are usually fueled by natural gas evaporated from its liquefied payload, which is much cleaner than burning diesel.

blitzar · a year ago
Looking around at how much garbage people dump in the streets I am sure we could chuck some of that in Drax and close the loop a bit.
alecmg · a year ago
Could it be quantified how much UK is using coal power of other countries?

Since industry is moved outside, the products we consume use power of producer country, mostly China. Is there a correlation in reduction of local coal power and amount of energy intensive products imported?

jillesvangurp · a year ago
It's all connected of course.

It's much easier to just look at the global consumption of coal. Peak coal usage was in 2022 (a brief spike caused by the Russian invasion of the Ukraine). With the exception of China and India, coal usage has declined pretty much everywhere. And in many western countries, like the UK and US it is being phased out rapidly; mostly for economical reasons. It's just no longer cost competitive.

China is still building coal plants but their usage seems to have peaked as well or be close to that as they have aggressively accelerated deployment of wind and solar there and are of course responsible for producing most of the growth of that. Also, there's a sense of urgency there because coal related pollution was making their cities unlivable. This is similar to what happened in the UK mid last century. Also, they are pursuing some aggressive short term goals to reduce dependence on coal.

TheBruceHimself · a year ago
On the flip side is really fair for a nation to claim their emissions aren't their responsibility because it was due to the production of exported goods? Would we accept that line from Germany if they decided to keep a coal plant open. "Oh, that's not our CO2, it's all going to make cars for China. It's their CO2". A little ubsurd when Germany gets rich off the sale. All the profit, none of the responsbility. If china wants to make our stuff I only think it's fair that they are responsible for the pollution caused by the production.

If anything else this narrative "exported CO2" muddies the water and makes it harder to hold nations to account. A basic "emissions in your borders are your responsibility to handle and reduce" is easy to understand, hard to game, and avoids this all devolving into CO2 accounting tricks.

ZeroGravitas · a year ago
CO2 is about 20% higher when accounting for imports:

https://ourworldindata.org/co2/country/united-kingdom#consum...

But both are still trending down.

WeylandYutani · a year ago
That is a good point. Europe has since the 1970s actually cleaned up the continent pretty well by kicking out a lot of polluting industry.

(The latest target of environmentalists in the Netherlands was data centers. They used too much power, water whatever. So they went to the deserts of Spain. Epic win).

baq · a year ago
What's interesting about 140 years is that there's probably quite a few people who are ~70 and their grandparents have seen the first coal power plant start up. It isn't really that long ago.

Such generator facilities need to be retained, and not demolished, for contingency purposes.
alex_duf · a year ago
The actual electricity production and consumption of the UK is declining [0] The UK is also rapidly deploying renewables, and adding more and more interconnection to mainland Europe.

So as the capacity goes up the consumption goes down (for now). It's completely fair to decommission all coal plants.

I assume the energy consumption will go up at some point, as there's only so much you can save with energy efficiency, an delocalisation, and as we shift primary energy usage onto electricity (what's currently being imported in the form of gas and petrol).

But hopefully by this point the continued growth of production means will cover the increase

happymellon · a year ago
I had understood that one of the reasons for the reduction in consumption was related to having one of the highest priced electricity in the world. With more being deployed it should bring prices down too to allow increased consumption. Hopefully.

It really does make things uneconomic here, and painful for the poorer folks in society.

Symbiote · a year ago
This is the plant that was retained. It was kept a little longer due to the problems with gas supply after Russia invaded Ukraine.

It's no longer needed for contingency.

mattlondon · a year ago
We don't need to keep coal for that. There is relatively clean by comparison gas stations for that. Or pumped hydro.

Or just build more wind and over provision

toomuchtodo · a year ago
Burn the ships, we aren’t going back. Net zero is within reach, the evidence and data on this is clear.

Mostly replaced with gas, which is probably just as bad for climate change https://www.spglobal.com/marketintelligence/en/news-insights...
mhandley · a year ago
The graph in the article makes clear that isn't really true. Around half of coal use was replaced by natural gas in the 1990s, as you say. That's still a win - same energy, but half the CO2 emmisions. But since 2010 or so, the remainder of coal use was largely replaced by renewables.

Now we just need to get rid of the remaining natural gas use. For electricity production, the trend here is pretty good. Natural gas won't disappear anytime soon, but there will be longer and longer periods where none is burned. But for home heating, I don't think gas will be phased out as fast as really needs to be done.

Electricity not power just to be pedantic. Most power is still from directly burning gas and oil.

cpressland · a year ago
At least it’s still lower on average than renewables at the moment [1]. I’m not sure what the current state of Nuclear Reactor construction is like, but hopefully we get some come online soon.

'Mostly' isn't true over the last decade which is the period of the most recent big shift from Coal.

That one looks only at carbon emissions, which is not the main issue with Natural gas. The problem is that since it's a gas it leaks and natural gas in the atmosphere is a very very potent greenhouse gas.Though ofcourse over time in will break down to simple co2
