Britain's reliance on coal-fired power set to end after 140 years (ft.com)

I took a course in my undergrad in physics on energy systems. It was basically a holistic look at the UKs primary energy sources, the grid, future sources of energy and some policy.

We briefly covered the elimination of coal. A graph showed a huge void in domestic energy at coal-plant closures, with other domestic sources planned in the future (renewables) to fill the void. These renewables sources have been much slower to come online and have been under resourced. The issue is now that we are enormous net-importers of energy, some of our demand is likely fulfilled by foreign coal burning. So none of this reporting is really that honest about how horrific it is to be a net energy importer, it would be another thing if we were at greater than 100% domestic energy generation and that these can now be taken offline (which many will take as the implication.)


https://ukerc.ac.uk/news/britain-net-electricity-exporter/ "Britain is a Net Electricity Exporter for First Time in 44 years" (2023)

OK, so that was the brief period when half the French nuclear reactor fleet had to be taken offline at the same time for crack inspections, but the other half of that - importing for 44 years - implies this is not a new situation nor a disaster. It is not "horrific" to be a net energy importer, nor is is particularly environmentally unfriendly when the French nuclear reactors are working.

The second most important link is importing energy from Norway, which is 99% (!) renewable.

The main delaying factor was the Conservative moratorium on building onshore wind in England, which I believe is ending, and the general reluctance to build new power lines to import more renewables from Scotland, Orkney etc.

Since someone complained, direct quote from article:

"So what happened?

Over the past year, French nuclear power stations had many maintenance problems which led to significant reductions in their output. In August, 57% of the country’s generation capacity was not being used. Despite a modest recovery, as of January 2023, 15 of its 56 reactors were closed for repairs. All this meant nuclear-reliant France had to import electricity from neighbouring countries.

This led to more electricity being generated in Britain than would otherwise have been the case, to satisfy the additional demand from France. So while Britain’s renewable generation was at a record level, its fossil fuel generation was also higher than in the previous year. Without the problems in France, 2022 could have been the first year that Britain’s wind, solar and hydro combined generated more electricity than its fossil fuels – a milestone that will happen anyway over the next couple of years."


One of Labour's more important policies is to repair the damage that the Tories did to the energy production system. The UK has a huge amount of potential wind energy just from off-shoring. Hopefully they'll start building onshore too and closing more of these ugly and polluting biomass plants.

Which damage?

The electricity system has done most of its decarbonising under either the coalition or Conservative governments, they used quite a lot of the machinery (the CfDs, capacity market, etc) setup at the end of the last Labour government but it has been the subsequent governments that have chose the annual budgets for the auctions as well as setting up the carbon budget system.

There have been only two things that I would regard as material mistakes in this time:

First, not adjusting the max strike price for offshore wind in AR5.

Second, changing the planning rules to make it very hard to build onshore wind.

Everything else, including things like the offshore bootstraps / HND which are now receiving FID (like EGL2 which was just approved), the upcoming decision on zonal pricing, and most of all the massive buildout of solar and offshore wind generation and battery storage has happened under previous governments.

It's arguably the only area of policy which has gone quite well over the last decade, so I'm intrigued which damage you have in mind.


Are there that many biomass plants? Or is it just Drax? Which is something of an asterisk in the "no coal" story, in that the UK's largest coal burner is still running, just on imported wood pellets. Supposedly from sawmill waste in the US and Canada. I'm not sure how "green" that really is.

I once did a back of the envelope calculation that if you tried to run Drax on domestic timber only you would consume every tree in the country within a year.



> Hopefully they'll start building onshore too and closing more of these ugly and polluting biomass plants

What's the issue with these? Biomass plants take the energy from biologically degradable farm and food waste that would otherwise decompose and degrade, releasing its energy as methane and other byproducts into the atmosphere, on either farm fields (where it contributes to overfertilization of fields and water bodies by runoff) or on dung piles/compost heaps.

Modern farming, particularly livestock farming, produces an awful lot of such waste that needs to be taken care of, and small but livestock-intensive countries such as Denmark or the Netherlands have to ship the biowaste across the EU because by EU regulations and practicality they cannot dispose of it domestically.

Biomass reactors make the process a whole lot easier. They take the biowaste, extract all energy they can by having bacteria and fungi break it down, burn the gas for electricity and district/local heating, and the solid remainder can then be landfilled safely.


I think you are mixing up three separate types of power generation

> Biomass plants take the energy from biologically degradable farm and food waste that would

Drax doesn't do that, drax burns wood pellets: https://www.drax.com/sustainability/sustainable-bioenergy/so...

There are biowaste plants, I think there is one in thetford, but they are dirty and produce more CO2 per kwhr than gas (from what I recall, do check that first.) The thetford one is an incinerator, so requires a lot of processing to remove water.

> Netherlands have to ship the biowaste

thats because its really high in nitrates, and will kill waterlife should it run off.

> Biomass reactors make the process a whole lot easier.

not at scale. They are dirty, difficult to run and are dangerous at large scale. They often need to be heated. They also use a lot of water.

You can use it to generate low grade heat though. but needs to be mixed with something like straw so that the balance of sloppy to twiggy is right (not a technical term...)


> In 2020, the Boris Johnson-led government decided to permit onshore wind power, and since December 2021 onshore wind developers have been able to compete in subsidy auctions with solar power and offshore wind.

Adding my reply that explains why your claim that there hasn't been a ban since 2021 is only technically correct while actually misleading as to the real effects (to this comment that's in a more prominent thread).

Pasting from https://news.ycombinator.com/item?id=41444838 :

Yes, there hasn't technically been a universal ban since a few years ago, but until this year legislation basically allowed NIMBY's to veto any new onshore wind farms with no way for local authorities to force approval through, which is why less than ten new onshore wind projects were approved England in 2021-23 compared to hundreds in Scotland. So sure, not officially a ban but it was effectively a ban.

And that's what the new government have fixed: https://www.gov.uk/government/publications/policy-statement-...


Why replace ugly coal with ugly windmills? Why not build nuclear plants instead?

Nuclear plants are essentially identical levels of ugly to coal: from the outside both are concrete cuboids with cooling towers.

Aesthetics are not a reason either way, or the UK wouldn't have had brutalism.

Actual reason is that nuclear is expensive, while wind is much cheaper even after adding costs for storage etc.

Also that the UK can't cross-subsidise the power plants from the military because they no longer have a big enough military to justify the nuclear weapons they already have, let alone a big enough militarily to justify the capability to breed more plutonium.


Doesn't the UK have some of the highest electricity prices in the world? They're on trend to drop below the world average for energy availability per capita too according to ourworldindata.com [0] and are already behind the EU, US and China.

Horrific is in the eye of the beholder, but the UK's energy situation is unimpressive. I'd call it horrific, it looks like they've been in a state of acute crisis since around 2000.

> Doesn't the UK have some of the highest electricity prices in the world?

no.

https://www.statista.com/statistics/263492/electricity-price...

> They're on trend to drop below the world average for energy availability per capita too according to ourworldindata.com

it's not energy availability. it's energy use. and yes, energy use should come down worldwide over time.


> no.

Yet your link shows the UK at number 4. And I note number 1 is Ireland.


Do either of you have a source with more than 29 countries in it?

Statistia comes up a lot, but the free content always feels like it's an ad for their paid stuff.


Not me. I was phrasing it as a question because I thought maybe someone would have a better source that showed otherwise.

That being said, China & India are managing <10c/kWh for ~1 billion people each. I feel pretty safe claiming that the UK does indeed have a horrific problem making electrons move through wires. 500% cost increase above par is an uncomfortable statistic.


I'm no expert in the UKs domestic energy, but at least looking at electricity mix charts it seems to me like growth of renewables after introduction (lets say 2005) from <5% to ~40% compensates the drop in electricity produced from coal (~33% to <2%) quite nicely. The huge drop in coal production starting ~2014 also doesn't seem to correspond to an increase in net electricity import, so I don't see what you're basing your claims on.

It's also news to me that the UK was ever self sufficient for energy in the last few decades. Most countries are at least roughly matching their electricity production, but almost all are huge energy importers for non-electric energy, so I don't quite see the issue (if e.g. most large oil producing countries were to suddenly stop exports, most of the world would be in huge trouble).

Why do you claim that this, which has been the reality for almost all countries over the last few decades, would be horrific?


https://www.gov.uk/government/statistics/energy-chapter-1-di...

This is what you want to look at. Really energy dependance is a complicated issue. You'd have to be living under a rock to not see how this dependance has rocked Europe (particularly Germany) since the Ukraine war. Energy price instability is an enormous social problem.


I'm no expert either but I do know that we have been importing significant amounts of energy from France for quite some time. This suggests to me that France has a huge surplus rather than just matching their own need.

France built out a huge number of Nuclear reactors in the 80s. Some 70% of it's electricity comes from Nuclear. Nuclear has a very low marginal cost so when it's up and running you want to run it at full power as much as possible. At times of low demand in France this means exporting as much of it as they can at whatever rate they can get for it. It's not that they have a huge surplus overall, it's just the economics make it better for them to export rather than load following.

The UK seems to import around 10% of its electrity https://en.wikipedia.org/wiki/Energy_in_the_United_Kingdom

""" Demand for electricity in 2023 was 29.6 GW on average (259 TWh over the year), supplied through 235 TWh of UK-based generation and 24 TWh of energy imports.[4] """

Hopefully this is paired with reduced coal burning in the places Britain relies on for power, and improvements in efficiency. The wastefulness of British houses is something to behold...

Of course, there's also the energy used to build things that Britain imports that used to be made domestically, not accounted for here.

Britain seems to be doing reasonably well w.r.t. energy imports though - https://www.statista.com/statistics/550304/electricity-impor...

From https://www.statista.com/topics/4938/energy-imports-in-the-u...

""" Although historically relatively self-sufficient in covering domestic energy demand, the United Kingdom’s dependency on imports has increased in the past few decades. With oil and gas fields on the continental shelf depleting and the government phasing out coal, the country has grown increasingly reliant on supplies from other countries. Energy dependency reached its peak in 2013, at nearly 48 percent. Thanks in large part to growing capacity additions of wind power and a decline in primary energy consumption, the dependency rate had fallen to some 35 percent since. This is notably lower than the European Union average. """


> The wastefulness of British houses is something to behold...

I'm reminded of how there was an "Insulate Britain" campaign group, using unpopular disruptive tactics; the outcome of that was the law changed and they got jailed for several years, and the British public could go back to not thinking about insulation again.


We have some of the oldest housing stock in Europe.

There isn't much space inside for insulation, one solution is thin wall insulation.

https://assets.publishing.service.gov.uk/government/uploads/...


In the North East of England, theres a point where these houses aren't even worthwhile purchasing to rennovate. Houses can be purchases easily for £60k but require at least that to modernize. But while you've done well to purchase a house for £120k, it doesn't reflect in the local market.

The solution would be to knock the house down and build a modern one on the reclaimed land. But you've just bought a mid-terrace, so that's out of the question.


I would be considered a monster for saying it but maybe it's OK if someone buys up a row of houses to knock them down and build new, warm apartments.

External wall insulation is your friend there. Its about £12k to do, possibly including windows. will reduce your heating needs by 3/4ths if done properly.

> We have some of the oldest housing stock in Europe.

Yeah. One of those complex issues that just keeps getting worse as you dig into it. I think people in the UK are much more conservative about historical preservation of ordinary houses, due to both percieved ugliness and build quality issues and also some genuine regressions of utility from, say, the days of the Parker-Morris standards.


Also we appear to be unable to build new houses at anywhere the rate needed to meet demand, so it's unsurprising that old houses are retained and that people are willing to live in houses with suboptimal energey efficiency...

Not to mention horrendous draughtiness.

Which was a feature, given historical reliance on coal fires inside homes for heating.

tbh it still is kind of a feature given that we (collectively) also don't really know how to ventilate old houses and many many who have tried to tackle the insulation problem live with terrible mould problems

How does it count if you import fuel and burn it locally? It's still "imported energy". Most of our energy is imported if you look at it that way.

The vast majority of imported energy comes from France and Norway, much cleaner energy than the UK.

> some of our demand is likely fulfilled by foreign coal burning

Actually very little. Most is French nuclear power. The electricity that the UK imports has a lower carbon footprint than the UK's domestic electricity.


Does this mean the UK is basically completely reliant on import of power for a base load or does the nuclear reactors and whatever hydro there is cover the need to offset the intermittency of renewables?

> These renewables sources have been much slower to come online and have been under resourced.

It's far worse, then have been over-resourced using green taxes on fossil fuels and are still not coming to fruition. When they lose their green tax subsidies, the cost of renewable energy will sky-rocket.

> The issue is now that we are enormous net-importers of energy, some of our demand is likely fulfilled by foreign coal burning.

When the sun doesn't shine and the wind doesn't blow, we have no other way to magic up energy. The thing that made the most sense was nuclear, but the UK also failed to invest in that too.

I think the UK is quickly heading towards energy insecurity, rolling black outs and high-priced foreign energy. This winter for example is already set to be overly expensive.


"Power" technically means more than mere electricity (or electric power). In the UK, the modern steam engine can trace its origins back to either 1764 or 1712 (depending on how you count). Even in the one in 1712 served to help lift coal out of a mine, a form of reliance. But even if we limit ourselves to steam trains and regular service, the Liverpool-Manchester railway from 1830 is also a form of reliance. In any case, Britain has been reliant on coal-fired power (in the broadest sense) for a lot longer than 140 years. And in the narrower sense, it took decades for electricity to be a bare necessity.

https://commonslibrary.parliament.uk/research-briefings/sn04...

>The UK’s dependence on imported energy looks set to continue to increase in the future. This, alongside higher fuel prices and increased concern over the security of energy supply has increased the attention on energy imports and exports over the past decade.

I get the achievement here. But it sounds like a very significant net negative for the UK.


It’s not all bad. UK has a lot of onshore wind energy potential that was banned from development to placate the shires. That ban is no more.

UK is also a good place for nuclear power with an almost complete absence of risk factors, though with the price of renewables it’s too late to exploit it to the level France has done.


It's a crying shame that we didn't build out nuclear in the 1980s as we would have been in an excellent position had we done that. Instead we have the Chinese taking 30 years to build our new reactor.

The French buildout was very definitely a reaction to the oil crisis. https://en.wikipedia.org/wiki/Nuclear_power_in_the_United_Ki... describes a similar process of thinking in the UK, which was abandoned in favor of privatizing the industry, and the PWRs were never built apart from Sizewell B.

I suspect the arrival of North Sea oil and gas eased the energy concerns in the 1980s.

> Instead we have the Chinese taking 30 years to build our new reactor.

It's still owned by the same company that operates all the French nuclear reactors, EDF, and I suspect that most of the people doing the actual work on site are British. China can certainly build new reactors in China. I wonder if it's same the general disease of Western project management which causes high speed rail to get more and more expensive and less feasible.


It was a shame that we didnt accept EDF's offer to build 10 nuclear plants for free* under around 2000.

* would need a gaurenteed strike price around something like 2005 electricity prices.

They would have been online by now as they were going to be the same type as the one that opened in finland


> UK has a lot of onshore wind energy potential that was banned from development to placate the shires. That ban is no more.

there hasn't been a ban since 2021:

https://www.gov.uk/government/news/biggest-ever-renewable-en...


Offshore wind has always been allowed.

Onshore wind was technically allowed but in practice the rules were so restrictive that it was very difficult to get any projects approved. So yes technically not a ban, but it was a de facto ban. https://fullfact.org/live/2024/jul/onshore-wind-ban/


Needs a (2018)

Probably worth looking at a briefing that is a bit newer - a lot can change in 26 years

I listen to a few podcasts on clean energy. Two of them are by Brits (Michael Liebreich's Cleaning up and Robert LLewellyn's Fully Charged podcast). So, the UK's energy market gets discussed a lot.

It's pretty interesting. Like many energy markets, the key challenges are actually legislation and policy related. The new government just removed a ban on new on-shore wind turbines. Which given that they are so cheap now is a sensible thing to do. The ban was madness to begin with of course. Offshore wind is of course also huge. And the UK has a lot of former offshore oil industry that is now adapting to doing offshore wind (a lot of overlap in tools and skills).

And while they are shutting down coal, they still have a huge former coal plant that is now burning biomass in London. That's a single plant that powers most of London.

Basically the way that works is that the Canadians and the British both subsidize this "green" and not so renewable power. The Canadians basically chop down what little proper ancient forests they still have on the west coast, which from an ecological point of view is criminally insane. The wood then gets shipped half way across the planet to the UK where it is burned. Shipping it of course involves burning a large amounts of nasty bunker fuel. There's nothing cheap, sustainable, clean, renewable, or green about this business. It's only economical because of the subsidies. And those subsidies exist because of fossil fuel industry lobbying and very willing politicians. That would be the same jerks that banned on shore wind in the UK.

Another key policy challenge in the UK is that energy prices are the same throughout the UK. Most of the cheap wind power is up north. Much of the demand is in the south. So they are firing up gas plants in the south at the same time they actually have a surplus in Scotland. And then prices in Scotland are high because the gas they use in the south is expensive. Even when they have more wind power than they can use and they rarely have a need for any gas power in Scotland. They are a net energy exporter most days of the year. And they are connected to the Norwegian grid which enables them to import hydro power from there.

Part of the solution is cables but installing those is expensive and challenging because it involves a lot of haggling with local councils and planning commissions. But the real solution is actually changing how this market works. This kind of change is much more challenging. Why move the power south when you can move the demand north? Variable pricing would cause that to happen.


Prices are also high in Scotland due to sparse population, the standing charge is higher.

A lot of the renewables up in Scotland also give incentives to the local population as a sweetener for the planning application, typically £5000 per annum per megawatt of installed capacity. This isn't really reflected in what people pay for energy, but it is a benefit of the energy transition for people living nearby.


>And while they are shutting down coal, they still have a huge former coal plant that is now burning biomass in London. That's a single plant that powers most of London.

Do you mean Drax? That's nowhere near London.

>And those subsidies exist because of fossil fuel industry lobbying and very willing politicians

Why would the fossil fuel industry lobby in favour of wood-chip biomass?


Which is the power station burning biomass in London? If it's SELCHP in Bermondsey, I thought that was mostly burning rubbish?

Sounds like they're thinking of https://en.wikipedia.org/wiki/Drax_Power_Station (200 miles from London, but burns "biomass" and powers 6% of the uk)

Sticking around to dismantle your old workplace sounds like a lot of fun. Cathartic even.

Dismantling fossil fuel infrastructure will free up enormous amounts of steel for recycling.

I wonder what they did or will do with all the ash, though.


Rye House power station dumped the ash in the nearby gravel pits of Lea Valley, which is quite good for orchids.

https://www.theguardian.com/science/2016/mar/23/plantwatch-s...


How interesting!

Much of it is reused as a cement additive. https://www.cemex.co.uk/fly-ash

A report on this: https://www.ukqaa.org.uk/wp-content/uploads/2016/01/UKQAA-As...

The fraction is larger than I would have guessed. I imagine they will now be working through stockpiles.


I wonder what they did or will do with all the ash, though.

If I am not mistaken, I believe they landfill it.


I'm not sure why, but reading the article I got an urge to just apply for a job to help clean up the site. The coal plant served us (humanity), and now it's time to clean up after ourselves and return the land for other use. It seems like a fitting final chapter of the coal era

There was a plan to convert the Cockenzie site into an assembly site for offshore wind turbines. I don't think that quite got there, but it now looks like there are plans to use it for landing offshore generation cables and for battery storage. Which is very fitting.

https://www.eastlothian.gov.uk/info/210547/planning_and_buil...


Makes sense . . . the grid infrastructure is already in place at that site.
