Yes. But these things can be orthogonal. Or actually brcause gas is expensive.

https://www.bbc.com/news/articles/crkep1vx3mro

The price for wholesale electricity is set by a bidding process, with each generating company saying what it would be willing to accept to produce a unit of electricity.

Once built, the cost of generating power from renewables is very low, so these typically come in with the cheapest bid. Nuclear might come next.

Gas generators often have the highest costs, because they have to buy gas to burn, as well as paying a "carbon price" - a charge for emissions.

The wholesale cost is set by the last unit of electricity needed to meet demand from consumers. This means that even if gas only generates 1% of power at a given time, gas will still set the wholesale price.

> Or actually brcause gas is expensive.

Gas in the UK is expensive because the Tories spent decades selling off the storage so developers could turn them into real estate. This continued well into the 2000's when, for example the lettuce (Truss) closed the Rough storage facility in 2017.

Gas in the UK is expensive because of 1980's privitisation. Another one of the Tory's great ideas. The UK privitisation model is designed to generate profit. Norway made a different choice. Equinor is majority state-owned, and Norwegian extraction operates within a framework designed to capture resource rents for public benefit. Britain privatised its way out of that option decades ago in the Thatcher-era and has never seriously revisited it.

Analysis from the University of Oxford[1] found that maximising oil and gas extraction from the North Sea would only save households £16 to £82 per year – and this would rely on tax revenues collected being distributed to households to offset their energy bills.

Dr Anupam Sen, co-author of the analysis, said the idea that “draining” the North Sea would make the UK more energy secure and significantly cut household bills is “sheer fantasy”. “We show that regardless of the remaining lifetime of North Sea oil and gas, a ‘drill baby drill’ approach to extraction would actually cost households more money versus continuing on our path to clean energy.”

The authors stress that savings gained from the clean energy transition are recurring annual reductions in bills which would continue indefinitely, whereas North Sea oil and gas are finite resources that would run out around 2040.

  • Exactly, and the Tories banned onshore wind, and refused to really invest in offshore wind. We've got the North Sea and its perfect for wind farms we should have had for decades

    • They didn't refuse to invest in offshore wind. Tories were the ones who started this ball rolling in the mid-2010s by breaknecking the removal of non-renewable energy production without any clear plan.

      The issue with offshore wind is that it isn't always windy. If you look at modelling with energy system with a high proportion of offshore wind, you need other sources of energy which often isn't factored into the economic return of the original investment.

      We are doing this because, for some reason, we have decided there is political capital in paying out these huge subsidies to large companies to produce expensive energy. I would think that would be obvious when the UK has extremely high electricity prices and renewable production is very high...where do you think the money is going? It is going to subsidise inefficient and expensive supply.

      Also, one of the primary issues with the UK is that the political system heavily incentivizes people to blame "the other side" for these issues. The Tories were extremely aggressive in moving towards green energy but people who vote for Labour, because they support green energy, will have to believe the opposite. There are other posts on this chain that also blame the Tories for things that didn't happen. In this system, it is very hard for anything good to happen and is how you end up with someone like Starmer who appears to have almost no opinions on anything other than staying in power and keeping the gravy train going for the lads. Not serious. Expect things to get significantly worse.

      Our electricity prices are much higher than anywhere else. I remember reading research last year that the cost of government intervention in so high that if gas prices tapered to zero, electricity prices would not fall. It is going to get much, much, much worse.

  • Why would additional storage make a significant difference to the price of gas?

    • Because if you have enough renewables and storage to eliminate gas from the mix you are no longer paying gas prices. The more often that happens, the cheaper your bills get.

  • The study you have linked is completely wrong.

    There is no international market for gas because export/import is physically complex. This is why gas is priced very differently despite it being chemically similar (unlike oil). Anyone who says anything different should be immediately disregarded as someone who should not have an opinion.

    This is technically true for oil but there are two other factors. One, importing oil is environmentally-intensive and relies upon the assumption of free and open trade in oil...hopefully, the last few weeks have demonstrated why this is untrue. Two, the assumption is that mix of imports is not changing, because of high energy costs and reduction in North Sea production, UK refineries are shutting down so we are completely losing domestic capacity across the whole space. We aren't importing oil, we are importing refined products, losing domestic chemicals capacity, losing margin. Lower jobs, lower tax revenues, more reliance on imports.

    The above take would be somewhat funny if we weren't ten years into seeing the consequences of this. At this point, we could be back to the stone age and you would have the same people screeching that inventing fire is dangerous (I worked in equity research in the mid-2010s...I remember when Cameron was really pushing hard for this, Clegg was saying how expensive nuclear is, etc. people in the industry were saying this would very badly...the issue is that the political cycle is far shorter than the economic cycle, all of this stuff is obvious but people in the UK run on the political cycle so if it isn't the newspapers, no-one normal reads them, next week then it will never happen...same issue with housing, exactly the same thing happened, we are now subsidising retail electricity which is impossible to get out of, I remember specifically this idea was thought of as an insane impossibility but producers were saying it would have to happen, and giving huge subsidies to producers...this is all obvious, obvious things happening are obvious, producers were fine, they get paid the subsidies but consumers are getting shafted AND consistently voting to get shafted).

    Also, Roughs storage facility is in the sea...so I am not sure what "real estate" development was done here (the UK has been building 10-20% of the required growth in housing stock for something like two decades...again, the same people will be screeching about developers if we lived in caves). The reason it was closed was due to economics.

    For some reason, you deny that producing more gas would be useful but are outraged at a storage facility closing when the primary function of a storage facility is to allow energy producers to arb derivatives markets effectively. I have no idea how this makes sense to you based on all of the above...perhaps you just want to complain about the Tories? I have no idea.

    The current tax rate on North Sea production is 75%, there was ample opportunity for public benefit but multiple governments took that money and spent it on benefits. The reason why Norway has worked is because they incentivized exploration (again, something that you imply later would have no benefit...but okay). The policy of the last fifteen years has been to tax the industry heavily and disincentivize exploration. Revisiting this approach is extremely unpopular amongst all politicians which is why production has dropped. Even with this limitation, we have large gas fields that have been blocked (by the Tories btw) for environmental reasons.

    This isn't complicated: if you want more oil and gas, produce it and create more incentives to produce it. The reality is that people want to have their cake and eat it: North Sea production is both very pointless but paying huge amounts of carbon to import from the Middle East is a good idea and we have to pay subsidies of 30-40% electricity bills to subsidies green production...which is also very profitable but requires subsidies because of Tory developers or something.

    The UK isn't a serious country. What is happening to the UK is a reflection of phenomenally poor political leadership. It is deserved.

    • > paying huge amounts of carbon to import from the Middle East is a good idea

      You are wrong here.

      UK oil has a very high carbon footprint.

      British North Sea oil is sour (high in sulphur). It is the "wrong" type of oil for UK refineries. So it gets sent to other countries around the world for refining.

      UK oil is viscous, waxy, crude which needs to be heated to pipe it. This means it takes a lot of energy to pipe (hello carbon footprint !) and it is not compatible with UK refineries anyway, so it has to be moved overseas (hello carbon footprint !!).

      UK crude is nothing like Norwegian crude and massively different from the stuff drilled in the Middle East which requires barely any refining in comparison.

  • Is gas expensive though? It's like 6p per kWh at the moment with electricity about 25p per kWh for consumers.

    I think gas is dirt cheap, heating your home and hot water with electricity is 4x more expensive and costs hundreds a month.

    • It’s only x4 more expensive to use electricity with old methods like immersion / resistance heaters

      Heat pumps are 400% efficient or more, so have parity or better with gas prices

    • You have to include the costs of conversion - gas power plant. Also you have some some losses during conversion from heat to electricity, a modern gas power plant can be up to 60% efficient.

      https://en.wikipedia.org/wiki/Gas-fired_power_plant

      Then you have electric distribution costs (costs for building and maintenance of electric grid, transformers, power lines).

      In many industrial process heat applications direct burning of gas is preferred, because it lowers the costs.

  • > Gas in the UK is expensive because of 1980's privitisation

    Post privatization domestic gas production rose 900%. Increasing supply = cheaper prices. Prices were low and stable at the time compared to today:

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

    This claim is the sort of dangerous ideological nonsense that is so common in Britain, and which has wrecked it. Literally every time socialist policies fail people come out of the woodwork to blame privatization, and yet invariably this made things better despite an often botched process. The American oil/gas industry is fully private and yet they have much cheaper energy: blaming Thatcher is dumb and not the answer.

    Gas in the UK is expensive because successive British governments wanted to have nothing to do with it and did everything they could to crush the suppliers. They thought deliberately deindustrializing the country was moral and ethical, for "climate" reasons. So they:

    • Imposed massive "windfall" taxes on the industry to the extent that nobody developed new sources

    • Then imposed very high carbon prices on it

    • Banned fracking

    • Stopped issuing licenses for exploration

    • Imposed price caps

    • Chased all the industry that needed cheap energy away to Asia

    • Shut down gas storage facilities, exposing Britain to the global spot price

    • Didn't build other reliable energy sources like nuclear or coal

    End result: high prices and shortages. There are graphs here that show how much of the British electricity price is artificially created by government:

    https://davidturver.substack.com/p/why-is-my-energy-bill-so-...

    Other countries didn't make all these mistakes together. And they were mistakes by the government. Really, can you even claim the British energy industry is private when the government takes 80%+ of its profits? Socialist policies always create shortages and high prices. Always.

  • The UK (and Europe) could produce much more gas and consequently control prices if they wanted. It is easy to always blame the previous government(s) but the current situation is policy across Western Europe.

    Edit: puzzled by the blunt downvotes for stating a noncontroversial fact. Over the last 15 years the US has invested in shale gas while the UK and EU have banned it. Even today the UK refuses expension of North Sea gas extraction. Whatever the reasons (environment, decarbonisation) it does mean that the situation we have now with gas across Western Europe is policy, not an unfortunate consequence of world events...

California is a great example; highest electricity prices in the US (not counting Hawaii, which makes sense) despite significant hydro and fantastic solar capacity. In the last few years California runs 100% renewable on many days (and growing) every year.

Economics 101: prices are not set by what goods cost to create + markup. Prices are set by how much people are willing to pay.

  • Why is it "people are willing to pay" and not "corporations are brazen enough to charge"? These utilities are necessities and relatively few people have access to cheaper alternatives to them.

    • The regulations mandate that the market operates that way. It's the government that should be held to account.

    • Because, under usual circumstances, self-interested corporations compete against each other to get as close to what people are willing to pay for energy as possible.

  • PG&E's prices are not a function of what people will pay though, it's a function of what people expect.

    CA wants green energy now (aggressive targets), needs to have fire hardened infrastructure (expensive upgrades), and wants full service to sprawling remote areas using modern infrastructure.

    The combination of these is incredibly expensive.

    If you don't believe me, buy PGE stock and get your dividend from their "greed". But honestly, the stock is an awful performer, because the actual problems facing them are real.

  • > In the last few years California runs 100% renewable on many days (and growing) every year.

    How many is "many days"? Gas is still used for at least one fifth of electricity. https://app.electricitymaps.com/map/zone/US-CAL-CISO/5y/mont...

  • I know nothing about California so please correct me if I'm wrong.

    You mention significant hydro and solar capacity in California. So minimal carbon externality: lung disease and climate change. If you consider that externalised cost into the cost of electricity elsewhere, does not California and other renewable-rich electric grids fare more competitive on price?

    E.g. the problem is not the expensive renewables in California, rather, the problem is that the cost of declining human and animal health and climate change is externalised for the fossil fuel.

  • Meaning it's supply. Overall dupply low because fossil fuels discouraged and penalized, demand high, price high.

  • California has high volumetric rates, but mostly that is because it has much more distributed generation than any other state, uses far less grid power, so the grid rates are dominated by fixed grid costs. Actual monthly electric bills in California are not remarkable at all. According to the EIA the typical residential electric bill in California is almost exactly the same as Texas: $174.59 vs. $173.94.

Yeah I'm in the UK and for electricity, I'm on the green Octopus Agile tariff, which tracks the wholesale price updating every 30 mins. Given the abundant green energy today, and peak times between 3-7pm, right this second I'm paying £0.02/kWh, but at 6pm, I'll be charged £0.40/kWh. In the coming months with gas supply reduced, and consumer demand steady, it will have a knock on impact to me given it tracks wholesale cost so I'll have to consider moving off the tariff given I'll be paying more overall.

They aren't orthogonal - the reason that gas is being used is because renewable can't reliably power the grid! If you look at something like https://grid.iamkate.com/ you can see that in the last 24 hours the gas peak is when the wind dies down and the sun isn't shining, around 6-8pm. Happens to be a real price peak at that time. This isn't some weird and unexpected outcome, we've had at least a decade of evidence with this sort of low-wholesale-high-retail price dynamic.

That isn't gas is expensive, it is simply policy that the UK, rather naively, is trying to run their grid 24/7 based on processes that are not available 24/7. That is an expensive trick to try and pull off. Poor people need a way to signal that they won't use electricity in the evening if they want to be able to afford power is my read on the situation. Not very civilised but if that is how the UK approaches reliable cheap energy as a target then it seems the most reasonable outcome.

  • Unfortunately for the UK, its geology means there isn't a lot of pumped hydropower storage unlike France, which is the cheapest way to bank intermittent renewables. In the places where there is pumped hydro capacity like Coire Glas, the operators are demanding the government guarantee they would be paid today's (natural gas generated) price to go ahead with construction, which would completely defeat the purpose of energy storage.

    And yes, letting nuclear power dwindle was a political choice, spurred by short termist bean-counter thinking:

    http://www.stross.org.uk/charlie/old/rant/torness.html

  • Seems like a very good case to get storage and power backup in people's homes. Industrial users could install their own gas fired generators. Residential consumers could have simple battery based backup, or even a generator which would double for helping during powerouts.

    • Bigger question is why they haven't already - these trends have been in place for a very long time and this current phase of the UK energy crisis has been on display for years. Anything legal and cost effective would have been done by now if the market had anything to say about it. Which suggests something odd is afoot. Maybe storage is more expensive than gas, maybe the UK government has regulated the option out of existence. Maybe something else.

I've read this before and I don't understand how this doesn't become/is untenable.

Doesn't this mean that solar/wind are insanely lucrative?

Also, this would mean that in order to really bring the price down, gas needs to be taken out as a source. But gas is typically the source that balances the grid because its output can be changed quickly. So price wise, you might get a drop but you would lose your ability to react quickly to fluctuations in demand

  • > Doesn't this mean that solar/wind are insanely lucrative?

    I used to work in wind energy in the Netherlands, it is only profitable there due to government subsidies. It was/is an enormously complicated system to understand on the whole. I was on the environmental impact side (visualizations) during the permitting process. It's high-risk & enormously expensive during the permitting process (i.e. getting permission to build the wind farm), and beyond that I understand it's a bidding process and again, super complicated on the energy trading side once you're operating. My experience was that the wind farm operators seemed to be doing well financially, but insanely lucrative? I'm not sure about that vs. non-renewables. Everyone I worked with (including myself) believed in green energy as a part of a larger mission to make the world a slightly better place. EU directives on renewables is what pushed the mission forward; the dutch on the whole (surprisingly), do not love wind turbines in their back yard.

    • :-( I'm sitting here looking at huge wind turbines out my front window and I absolutely LOVE them. I get to live in a solarpunk future where I can get where I need to without a car, my kids run out the door and play without getting run over, and I can see clean energy being made for my home (and that of my neighbours).

      I'm sure a lot of the cranky old people near me don't like them, but they hate everything and go out of their way to find things to complain about, to be honest.

  • Yes, and I think that’s actually intentional, they’re rewarding renewables way over the odds without needing to give politically controversial benefits. The rewards are just an inherent result of the existing system. This is why renewables are growing rapidly in the uk.

    Of course we’ll need a way to resolve fluctuations both rapid and slower. Rapid fluctuations are handled by pumped hydro and increasingly by batteries.

    The slow fluctuations (day/night all the way to summer/winter and good/bad weather patterns) are much trickier, I think it’s still unclear how well handle them, but it will certainly be partly handled by having an excess of renewables, though we’ll likely need some other solutions too, nuclear is probably one of them.

    • The irony is that your comment should be entirely inverted. Renewables are not rewarded way over the odds - in fact the ruling party banned onshore wind entirely and i remember them banning at least one offshore wind farm. Luckily it is very cheap to build.

      Now Hinkley Point C is another story. It's a hugely expensive boondoggle which is taking decades to construct at enormous cost and the reward at the end is that they are rewarded with a strike price that is 3x that of solar and wind. That is an obsecene subsidy forced on to customers for a power source that cant even do load following and doesnt help with fluctuations in supply and demand.

      The slow fluctuations on cold, windless nights or when nuke plants are down for unplanned maintenance are going to be managed with gas.

      Maybe one day it'll be gas synthesized with electricity from solar+wind overproduction on a day like today. The roundtrip is expensive, but will still be cheaper than nuclear power on a windy, summer day.

  • > Doesn't this mean that solar/wind are insanely lucrative?

    This is how markets are supposed to work. It provides an economic incentive for production to increase, which is what we want.

    Consider what happens if you develop a farming method to produce potatoes for a fraction of the usual cost, but you can only meet 10% of total demand at your local market. What price are you going to sell your potatoes for when you show up to the market? You (like any free market seller) want to maximise your return, so you'll be able to sell for a fraction under the previous market rate, undercutting everyone else. Your farming method would be extremely lucrative.

    • Sure, but those same free markets will happily see those expensive producers go out of business. In the electricity scenario, that would mean blackouts.

      If you triple the price, you don't have a new gas plant appear out of thin air. And the result won't really be lower consumption either, because most people would have fixed rate contracts (not in the UK so don't know specifically, but this is very common elsewhere)

      1 reply →

    • Yes, but here’s the thing: you don’t have a monopoly over your potato farming method. Lots of new farms are built, and the more that do, the more the average price of a potato drops. Your expected return starts to drop. Yours - and everyone else’s - profit margins get squeezed.

      Investors begin to refuse to build new potato farms because a return on their investment gets worse whenever anyone decides to build a new farm.

      But the people need potatoes and more potato farms! The government issues an incentive scheme to guarantee a minimum price for each potato sold. Potential farm owners bid against each other for the lowest price, but it means they can build a farm and expect to break even.

  • Not only is it insanely lucrative, but the government enters into "contract for difference" contracts that guarantees a price per MWh that are generally above market rates, taking out most of the financial risk.

Which, importantly, drives more renewables and storage development because it makes the renewables fantastically profitable to run: near zero cost for you, but paid the price set by gas.

Renewables may be the cheapest at spot values, but there needs to be a way to price in the intermittent nature of the power.

  • People disliking renewables always say this.

    Then when asked what method to price in the Swedish nuclear fleet having ~50% of capacity offline multiple times last year and France famously having 50% of the capacity offline during the energy crisis I always get crickets for answers.

    It’s apparently fine when nuclear plants doesn’t deliver, but not renewables.

    The difference with renewables is that it’s even easier to manage. Their intermittency is entirely expected and the law of large numbers ensure we never have half the capacity offline due to technical issues at the same time.

> The price for wholesale electricity is set by a bidding process, with each generating company saying what it would be willing to accept to produce a unit of electricity.

Without mentioning how Contracts for Difference (CfD) works, this is a slightly disingenuous oversimplification.

Well explained, thank you! This is called the marginal price. Many people are not aware of this and are then think renewables are expensive.
