Ok, I must have missed this but ... Wind produces 16% of UK electricity, and nuclear produces 13% .... Ok wow. I assumed solar would be the thing that takes over, and In Spain that's probably true. But here it seems wind is going to be a win. Anyway I still need to work out how to spend my declining years - how to write software for renewable energy farms ... wind or solar.

  Predictive maintenance software for renewables assets is a fairly large area of growth.

  Well bare in mind that capacity's different from the current (as in now, not amperes.. but that too) generation on this Winter day. (Not saying it does go the other way in capacity though, I don't know.)
- DrScientist 4y ago
  The UK is one of the best positioned countries in the world in terms of natural wind resource. This is because large parts of the north sea are shallow/have banks that very large offshore wind farms can be built on. No terrain to get in the way, no people to object about it being close to their house. Scotland is also windy and not that populated and so has quite a few onshore farms. Eg see. https://orsted.com/en/media/newsroom/news/2022/08/20220831559011#:~:text=%C3%98rsted%20is%20proud%20to%20announce,clean%20and%20secure%20renewable%20energy https://orsted.com/en/media/newsroom/news/2022/08/2022083155....

        It depends who owns the energy production. If the government keeps a stake then they can use the additional profits to shield consumers from prices.

        > Electricity prices would still be through the roof. The prices are all set on the international markets. Only to the extent that electricity can be imported and exported via international connectors, which are of course limited in their capacity. Prices are not set internationally, but domestically. Energy is not a tangible, stored commodity like coal which is internationally priced. If what you said was true then America's electricity would be priced the same as Europe's, whereas it is way cheaper. Therefore building out additional electricity production in the UK could well lower prices, depending on matching of demand and supply, agreed prices in contracts, length of contracts, etc, and of course whether additional connectors are deployed.

        Gas prices are a big component of electricity prices at the moment and they are mostly imported.

  In UK wind is actually broadcasted to take over. After the new line connecting with Norway (for hydro storage) the majority of investments are going into wind. On Nuclear, I think right now there is 1 big nuclear plan offline for maintenance so there might be some of that too. In the Mediterranean area, while there is more prevalence of solar, it's not a clear winner either. For instance in Italy there is quite an aggressive law on usage of agricultural space for big solar farms. Solar will win in the decentralized, domestic space, an area that I'm highly interested in. At scale, Wind seems to offer a better ROI, especially on country on the coast line (or other favourable morphological characteristic) I'm heavily looking to switch to work on the space (from more traditional consumer products), but it's a more full stack space: software is written as a byproduct of the hardware. unfortunately I haven't found any Electrical engineering interesting in doing something in the space. Shameless plug if there is someone out there interested.
  - cjrp 4y ago
    I read/heard somewhere that if the Republic of Ireland built all of their potential offshore wind-farms, it could power the country and generate a surplus for export. Obviously need to solve the storage issue or rely on interconnects for when the wind isn't blowing/blows too hard.
    - mrspuratic 4y ago
      The east coast around Dublin (fortuitously, as the major population center) has good banks in relatively shallow waters ~10-20km offshore (Oriel, Kish, Bray, Codling, Arklow banks). There are only 7 offshore turbines in operation today (Arklow, 2003 25MW, planned expansion deferred), but hundreds more planned within the next 5 years. Less wind than the west or north coasts, which is seemingly less amenable, but there is at least one bank planned for Galway. https://gis.seai.ie/wind/ https://gis.seai.ie/wind/
  - stuaxo 4y ago
    The Tories said no to onshore wind, now solar is getting really cheap they are banning the building of solar on most farms (by reclassifying low quality land as higher quality land that must be used for food). At the same time they are thinking about allowing wind on land again (probably because it will no longer be the cheaper option). Given their links to fossil fuel interests it comes across as delaying tactics.
- jl6 4y ago
  The UK is too northerly and has too little spare land for solar to dominate (it will of course still play a large role). Wind is where it’s at. The UK has a vast and windy offshore domain.
  - DrScientist 4y ago
    Agreed. But note that a lot of the local solar capacity doesn't actually show up on the grid production numbers. ie if you have a solar panel on your roof and mostly use it to reduce the power you take from the grid, all you will see in the national numbers is lower demand, not increased production.
    - cjrp 4y ago
      Don't most domestic panels actually feed into the grid (so presumably would show up on the stats as solar generation)? Unless you've got a battery system at home.
      - DrScientist 4y ago
        They do - but as the rate you are paid for electricity is now a fraction of the price you are charged, most people without a battery try and align their energy use with production. ( The suns out! Put on the washing machine/dish washer etc ).
        phas0ruk 4y ago
        Not if you locked in a feed in tariff from years ago. They lasted 15 years I think.
        DrScientist 4y ago
        Sure - don't know what proportion of solar panel installations that is though - it was an early adopter incentive. Bottom line - not all the local solar production is measured at the grid level - much of it results in demand reduction which can't be directly attributed. I think this will only increase - either due to local batteries, or more electricity driven heating systems ( heat pumps for example ). And this isn't just homes - if you have a farm and have a big water reservoir which you fill by pumping water - and you had some solar panels - you'd just run the pumps when it was sunny - there is no particular need to run them at particular times ( same if you had a wind driven pump ).
- pydry 4y ago
  Ideally you'd have a mix since they anticorrelate. If it's generally sunny when there's little wind and windy when cloudy why wouldnt you? (this is one reason why the amount of storage required for an all solar/wind grid is usually vastly overestimated).
  - snickmy 4y ago
    I'm not sure the anticorrleation has ever been proved. While it seems logical, the cloudy / stormy weather that sometime we experience in UK is too harsh for wind farms
    - magnetic-recoil 4y ago
      Named storms often generate records for wind power generation. Even if a few turbines in the middle of the storm have to turn off, the rest of the country still gets lots more wind. If you look at graphs of the wind and solar production in winter vs summer, the correlation is obvious. On a day-to-day basis, much less so, but on average low wind does tend to come along with higher sun.
      - DrScientist 4y ago
        It's complicated by the fact that the relationship between wind speed and power isn't linear - it's cubic - double wind speed - 8 times the power! This only happens in the designed operating window ( too light you get nothing, too strong you need to shut down ). So one question is what window have your tuned your farm for? Air density matters as well - the denser the more power - ie the colder the more power.....
  - DrScientist 4y ago
    Isn't it the sun's energy that ultimately creates the wind - through differential heating? So whether it's anti-correlated might a local feature depending on the local factors driving the weather? Perhaps stronger correlation would be that air movement ( wind ) is the thing that drives the weather changing. ie no wind, means slow change ( though the opposite isn't necessarily true - if you are in the centre of a cyclic weather system which isn't moving you could have wind and not much change ).
- pjc50 4y ago
  Wind is huge, while the last nuclear plant completed in the UK was in 1995. https://www.imeche.org/policy-and-press/from-our-perspective/energy-theme/nuclear-power/about-nuclear-power/nuclear-uk/britains-most-recent https://www.imeche.org/policy-and-press/from-our-perspective... > how to write software for renewable energy farms ... wind or solar.

  > I assumed solar would be the thing that takes over Solar in the UK is highly seasonal. A ~4kW installation that generated 500kWh in June might only produce 50kWh in December [1] - whereas a ~4kW install in Spain might generate 700kWh in June and 200kWh in December [2] So if you want power output in December, Solar in the UK isn't the best choice :) [1] https://pvoutput.org/aggregate.jsp?id=43099&sid=39381&v=0&t=m https://pvoutput.org/aggregate.jsp?id=43099&sid=39381&v=0&t=...

  Yeah wind is going well these days. The annual average is around 30%. I've seen it at 60% on a good day.

You can also view the effects of a frontpage post on HN here: http://www.gridwatch.templar.co.uk/admin/ http://www.gridwatch.templar.co.uk/admin/
- ls65536 4y ago
  In case anyone else is wondering why the effects of being on the HN front page look small at first glance, notice the logarithmic scale being used for the y-axis. At first I thought the increase in traffic, while noticeable, didn't look particularly impressive on those graphs, but then I noticed that those diurnal traffic patterns looked a bit strange, which is when I noticed the log scale!
dottedmag 4y ago
Fascinating! The data shows pretty clearly that combined-cycle gas turbines are still THE type of power stations that are used to balance the supply and demand, but solar is already helping a lot during the day. French data shows gas power stations produce up to 9GW (~13%), and without solar they would be used to produce 12.5GW (~19%).

  https://www.youtube.com/watch?v=37M7ffjro3I https://www.youtube.com/watch?v=37M7ffjro3I I have posted this before, but this is an interesting explanation from 2020 detailing what fuels UK electricity generation.

Is wind an efficient way to produce electricity? Would we be producing wind turbines if there were 0 subsidies?
- fredley 4y ago
  Most windpower in the UK is offshore, and yes it's a great way to produce electricity, particularly here! https://en.wikipedia.org/wiki/Wind_power_in_the_United_Kingdom https://en.wikipedia.org/wiki/Wind_power_in_the_United_Kingd...
- magnetic-recoil 4y ago
  Offshore wind in the UK currently uses the "Contracts for Difference" payment mechanism. Operators bid to build turbines, and the best value operators get assigned areas of the sea. Then, they receive a fixed price from consumers for any electricity they generate (effectively, but there's market mechanisms in there that complicate the accounting). Initially, this was much more expensive than fossil electricity, but the price of turbines has dropped and the price of fossil electricity has grown, so now existing wind turbines are lowering the price consumers pay for electricity. New wind farms have achieved CfD rates of less than £0.04 per kWh, which is not a subsidy for the wind farm operators, but rather a subsidy for electricity consumers as this electricity is far cheaper than market rates.
  - DrScientist 4y ago
    Adding to that, they are now looking at local hydrogen production from wind excess. While not nearly efficient as using the electricity directly, it's more efficient than throwing it away. Also the offshore farms sit in a pool of the raw material ( water ).
    - snickmy 4y ago
      for record, best electrolysis for hydrogen is a 50% efficiency end-to-end conversion.

The National Grid Pressure maps are also interesting. https://gasdata.nationalgrid.com/ https://gasdata.nationalgrid.com/ The network is used for short term storage to even out supply and demand.
cm2187 4y ago
I find https://gridwatch.co.uk/ https://gridwatch.co.uk/ a bit more readable. At the bottom of the page you can click on each energy source to see those metrics for that source only (worth doing to understand the volatility of wind in particular if you haven't seen those charts already)

On Friday, December 9th at ~4:00pm GMT (Greenwich mean time): Nuclear: 5.25 GW Wind: 3.84 GW Combined Cycle Gas Turbines: 23.31 GW Solar (Estimated): 0.35GW Installed Wind Capacity (onshore + offshore): 25 GW [0] Installed Solar Capacity: 13.4 GW [1] Total installed Wind/Solar: 38.4 GW. Total produced: 4.11 GW Wind is currently producing 15% of its installed capacity. Solar is producing 2.6% of its installed capacity. Combined, the renewables are at almost 11% of their installed capacity. Gas turbines are making up the difference. Lots of you are cheerleaders for "renewables". They seem like a transitional technology to me. If hydrocarbons are ever going to be retired from use, nuclear sure does seem like the only option. It seems to me like humanity's only hope is a breakthrough in our understanding of the laws of nature.

  There's a few things that help with periods of low wind: More long distance transmission / interconnects Vehicle-to-grid Grid scale battery storage Domestic and commercial battery storage (Powerwall etc) Seasonal thermal storage - large insulated tanks or ground source heat pumps These all exist, and there will be more new technology coming. It doesn't seem like an unsolvable problem.
  - pydry 4y ago
    Also being 5x cheaper than nuclear power.
  - Schroedingersat 4y ago
    You don't even need vehicle to grid. Just a discount for charging when there's curtailment. Most regions can get by with no storage using that one change.

  An enormously expansive area nearly 3 times the area, mostly full of cheap land a full 20 degrees of latitude further south isn't very surprising to have more solar and the continental-ocean boundary generates powerful midday wind, exactly when you want it. For all the coal rolling, capital knows when there's a good deal going.

A ~4kW installation that generated 500kWh in June might only produce 50kWh in December [1] - whereas a ~4kW install in Spain might generate 700kWh in June and 200kWh in December [2] So if you want power output in December, Solar in the UK isn't the best choice :) [1] https://pvoutput.org/aggregate.jsp?id=43099&sid=39381&v=0&t=m https://pvoutput.org/aggregate.jsp?id=43099&sid=39381&v=0&t=...

Yeah wind is going well these days. The annual average is around 30%. I've seen it at 60% on a good day.

You can also view the effects of a frontpage post on HN here: http://www.gridwatch.templar.co.uk/admin/ http://www.gridwatch.templar.co.uk/admin/

In case anyone else is wondering why the effects of being on the HN front page look small at first glance, notice the logarithmic scale being used for the y-axis. At first I thought the increase in traffic, while noticeable, didn't look particularly impressive on those graphs, but then I noticed that those diurnal traffic patterns looked a bit strange, which is when I noticed the log scale!

Fascinating! The data shows pretty clearly that combined-cycle gas turbines are still THE type of power stations that are used to balance the supply and demand, but solar is already helping a lot during the day. French data shows gas power stations produce up to 9GW (~13%), and without solar they would be used to produce 12.5GW (~19%).

Is wind an efficient way to produce electricity? Would we be producing wind turbines if there were 0 subsidies?

fredley 4y ago
Most windpower in the UK is offshore, and yes it's a great way to produce electricity, particularly here! https://en.wikipedia.org/wiki/Wind_power_in_the_United_Kingdom https://en.wikipedia.org/wiki/Wind_power_in_the_United_Kingd...

Offshore wind in the UK currently uses the "Contracts for Difference" payment mechanism. Operators bid to build turbines, and the best value operators get assigned areas of the sea. Then, they receive a fixed price from consumers for any electricity they generate (effectively, but there's market mechanisms in there that complicate the accounting). Initially, this was much more expensive than fossil electricity, but the price of turbines has dropped and the price of fossil electricity has grown, so now existing wind turbines are lowering the price consumers pay for electricity. New wind farms have achieved CfD rates of less than £0.04 per kWh, which is not a subsidy for the wind farm operators, but rather a subsidy for electricity consumers as this electricity is far cheaper than market rates.

  Adding to that, they are now looking at local hydrogen production from wind excess. While not nearly efficient as using the electricity directly, it's more efficient than throwing it away. Also the offshore farms sit in a pool of the raw material ( water ).

    for record, best electrolysis for hydrogen is a 50% efficiency end-to-end conversion.

The National Grid Pressure maps are also interesting. https://gasdata.nationalgrid.com/ https://gasdata.nationalgrid.com/ The network is used for short term storage to even out supply and demand.

I find https://gridwatch.co.uk/ https://gridwatch.co.uk/ a bit more readable. At the bottom of the page you can click on each energy source to see those metrics for that source only (worth doing to understand the volatility of wind in particular if you haven't seen those charts already)

On Friday, December 9th at ~4:00pm GMT (Greenwich mean time): Nuclear: 5.25 GW Wind: 3.84 GW Combined Cycle Gas Turbines: 23.31 GW Solar (Estimated): 0.35GW Installed Wind Capacity (onshore + offshore): 25 GW [0] Installed Solar Capacity: 13.4 GW [1] Total installed Wind/Solar: 38.4 GW. Total produced: 4.11 GW Wind is currently producing 15% of its installed capacity. Solar is producing 2.6% of its installed capacity. Combined, the renewables are at almost 11% of their installed capacity. Gas turbines are making up the difference. Lots of you are cheerleaders for "renewables". They seem like a transitional technology to me. If hydrocarbons are ever going to be retired from use, nuclear sure does seem like the only option. It seems to me like humanity's only hope is a breakthrough in our understanding of the laws of nature.

There's a few things that help with periods of low wind: More long distance transmission / interconnects Vehicle-to-grid Grid scale battery storage Domestic and commercial battery storage (Powerwall etc) Seasonal thermal storage - large insulated tanks or ground source heat pumps These all exist, and there will be more new technology coming. It doesn't seem like an unsolvable problem.

  Also being 5x cheaper than nuclear power.
- Schroedingersat 4y ago
  You don't even need vehicle to grid. Just a discount for charging when there's curtailment. Most regions can get by with no storage using that one change.

There is a reason [1] why Solar is only generating a small fraction of installed capacity. [1] https://en.wikipedia.org/wiki/Night https://en.wikipedia.org/wiki/Night

I really enjoy this one: https://app.electricitymaps.com/zone/GB https://app.electricitymaps.com/zone/GB It shows energy sources for all of the countries in Europe on a map, import/export, prices and CO2 intensity.
- bearbin 4y ago
  The visualisation on that site is good, but it's sadly plauged with data errors. The UK data doesn't seem to correspond to any other source I can find. I think it might be delayed by 24 hours, but even that doesn't seem quite right...

      Well, that issue explains a lot. The data source went missing, so the website just made up some data and used that instead! That whole website is a nonsense, what's the point in visualising imaginary data and pretending it's real...

        Totally agreed. May be the top link change to non-lying site so not to affect all the good works of others.

I'm guessing NordPool has something like that somewhere on their site (probably not as cool looking though), but what I found interesting is this: https://umm.nordpoolgroup.com/#/messages?publicationDate=all&eventDate=nextweek https://umm.nordpoolgroup.com/#/messages?publicationDate=all... It's the notifications for all production and transmission in Europe coming online and going offline with power and dates.

Texas and GB seem to have similar levels of demand, but Texas seems to have quite a bit more wind/solar.

An enormously expansive area nearly 3 times the area, mostly full of cheap land a full 20 degrees of latitude further south isn't very surprising to have more solar and the continental-ocean boundary generates powerful midday wind, exactly when you want it. For all the coal rolling, capital knows when there's a good deal going.
