    Oh no how will they survive as a country after all you told us this is not possible /s

    Meanwhile we remain the most expensive in Europe while producing 20x co2 of France today

    Right-wing populist proposes nuclear while restricting renewables… che sopresa!

    For countries that already have (or had) a nuclear infrastructure, then reactivating or expanding that resource is a pragmatic use of a sunk cost - they still need to clean up the mess after, so it’s worth getting as much good out of it all beforehand. However, doing so while reducing or eliminating renewables is a policy purely driven by “anti-green” mania: every country in Europe with a cheap energy system uses both nuclear and increasing amounts of renewable energy.

    The primary reason to use nuclear energy is to remove dependence on fossil-fuel; without large amounts of renewables in the mix, you become reliant on expensive gas peaking to meet demand, or cover for scheduled outage - hardly a great way of keeping energy costs down.

    (Yes, I do think Germany was stupid to shut its nuclear fleet, slow down its renewables rollout and rely increasingly on cheap Russian gas, but I think we know by now that Schröder had at best mixed loyalties there. Japan’s shutdown was different: this was driven primarily by safety concerns about the earthquake resilience of older sites in the wake of the Touhoku tsunami; Japanese operators have been slowly bringing selected plants back on line after extensive engineering reviews and remedial works, but some reactors have been permanently decommissioned)

    LOL.

    If EDF were building NPPs in Poland, The Czech Republic and Slovakia rather than Westinghouse and KHNP you would be the first on here questioning their credibility.

    We are not our neighbours. We have no nuclear. No offshore generation, and will not have this side of 2030, and two of the four granted strike prices I would view with the same scepticism I viewed Sceirde Rocks at the same stage.

    They have 5.9 GW of nuclear, are adding a further 6.4 GW, and all with over twice the capacity factor and three times the lifespan.



  • Registered Users, Registered Users 2 Posts: 9,235 ✭✭✭Markcheese


    Actually - that raises an interesting point -.if we were to consider building a NPP what countries regulations and standards would we follow , - probably a bit daft to make up our own ( no experience,cost , time .ect ) ,

    So if you were to follow UK or French,or US standards - who would you get to oversea the design and build, again we wouldn't be doing it ourselves - but you don't want to be getting ex- EDF or ex-westinghouse engineers to effectively oversea their mates .

    I suppose in that sense maybe a British team - theyre have loads of experience of EDF tech ,but arent necessarily nationally invested in, or biased towards it ..

    How Much Does a Battery Storage Plant Cost in 2026? ROI & Design Guide - AnengJi Energy https://share.google/QKmLLUM0hWlkMMUYW

    Dont forget , yes the ESB has made it expensive to build grid storage ,batteries or pumped storage -

    But they've also made it expensive to build gas and wind-turbines - and likely expensive to build nuclear, - any cheap government financing,and streamlining of energy planning and development laws and regs,will likely benefit all energy projects ..

    I doubt we'll ever get to the stage where we'll build more than a few hours worth of grid storage .. which in fairness would be great..

    Also , Nuclear would also need the same batteries and a level of storage to handle peaks and flows in demand..

    Why would I questioning their credibility? Currently nobody other than the EDF is building any Nuclear in Europe.

    Thats why they are the only credible test case for Nuclear. If we want to be building Nuclear here we should be basing it on costings for it like we see at Hinckley or Sizewell? And sure maybe they make sense even with that.

    Like again, I'm relatively speaking neutral on Nuclear and if shelling out 30bn on a Hinckley clone in Ireland made sense then I wouldn't necessarily be opposed to it.

    But lets not pretend that it *won't* cost that much.



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    If you are going to base your decision on the cost of an alternative plan involving nuclear, before you start looking at anywhere else as a comparison, then you are going to first have something to compare it too. And that would be the cost of the present plan taking into account the relative lifespans and capacity factors.

    So why are you and others here so seemingly knowledgeable in all things nuclear in opposing it, yet cannot even give as much as a single figure for the current plan we are following ?

    Far as I can see there can only be two reasons. You do not know, or you do know and it is financially insane.



  • Registered Users, Registered Users 2, Paid Member Posts: 1,736 ✭✭✭Consonata


    We have figures for what it costs to build wind turbines in Ireland, in the UK and elsewhere in Europe because it's a relatively common, cheap, form of power.

    We have figures for what it costs to build solar panels in Ireland, in the UK and elsewhere in Europe because it's a relatively common, cheap, form of power.

    We have figures for Nuclear as well. However there is only 1 nuclear provider in this region, the EDF, the only company that has an actual proven track record of building Nuclear.

    Hanging all our hopes on cheap nuclear on companies or countries which haven't ever built Nuclear in Europe, or in the case of westinghouse, several decades. This to me would seem insane.

    So, if we are to discuss building Nuclear in Ireland, we should at the very least, discuss it in the context of companies who actually have a proven track record.



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    You are either getting ahead of yourself again, or just performing further gymnastics attempting to again avoid answering the question.

    If you know the cost of wind farm turbines on shore, fixed offshore and floating offshore and their relative capacity factors and lifespans, as well as the same for solar farms, - plus the cost of green hydrogen production and cost to the consumer when used ,- then you have all you need to work out, not just the cost of this current plan, but also the cost of electricity to the consumer by continuing to follow it. So why not show it ?



  • Registered Users, Registered Users 2, Paid Member Posts: 1,736 ✭✭✭Consonata


    It's pretty much impossible to cost the end energy cost to the consumer after 20-30 years of investment in any field. This would be as much true for Nuclear as it is for Renewables. The best we can do is cost out how much it is to build the capacity.

    We know how much it is to build a wind turbine , we're quite good at building wind turbines. We have no idea how much it costs Korea or Westinghouse to build a nuclear plant in Europe. They have yet to do so.

    Known costs > Unknown costs every day of the week.

    Hence my argument is that if you are to fly the flag for Nuclear in this country, the only real game in town is the EDF.

    Because their costs are known.

    Vs 200bn+

    One solution costs tens of billions and is proven to work today the other costs and order of magnitude more in the hundreds of billions and works nowhere

    Focusing on cost when the current path (where we already built 9GW of renewables) if it ever completes and has already led us to have the most expensive (and still dirty) electricity in Europe is mad



  • Registered Users, Registered Users 2 Posts: 30,004 ✭✭✭✭end of the road


    ultimately, there is no future for nuclear in ireland.

    expensive, unreliable and requires large scale backup which would and could be scaled just that little bit more to be our main energy source for a fraction of the cost.

    the time was in the 50s to the 70s, maybe the 80s at a stretch but we were broke then.

    but now, it's time to move on, it's old tech.

    I'm very highly educated. I know words, i have the best words, nobody has better words then me.



  • Registered Users, Registered Users 2 Posts: 10,207 ✭✭✭✭Birdnuts


    Yet plenty will be imported while our current energy policies lock us into sky high energy bills - and thats b4 the madness of the current governments Data centre policies are full unleashed….



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    It`s not impossible to cost the end energy cost to the consumer after 20 years for electricity from any source when you know the Capex, the strike price, the capacity factor and the lifespan.

    If you believe it is impossible, then does it not follow that you must also believe that our current plan is nothing more than an uncosted wing and a prayer ?

    Actually the cost, when you know the above four figures, is fairly straight forward mathematics. The hydrogen factor would be a bit more complicated - a lot of very unrevealed expenses for whatever reason - but again from the strike price you could get a high degree of accuracy.

    You have already stated you know the cost of turbines, we know the strike price, the capacity factor and the lifespan so what would be the cost per GW of that 37GW offshore proposal and how would that effect the price to the consumer with or without hydrogen ?



  • Registered Users, Registered Users 2 Posts: 30,004 ✭✭✭✭end of the road


    we have high energy bills because in this country along with the UK, the consumer is expected to pay the greater share of the costs associated with energy + the reliance on high expensivity gas.

    in france and others, the tax payer pays the greater share, so if you want cheap electricity, then subsidization is the only option as even cheap renewables can only go so far.

    I'm very highly educated. I know words, i have the best words, nobody has better words then me.



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    That has not been how the French have kept electricity charges low. Since 2011 until last year French nuclear was supplying ARENH with 100 TWh of electricity at €42 per MWh. That has now been replace by the New Universal Nuclear Levy (VNU).

    With their nuclear being state owned and supplying 70% of their electricity, the money France makes from the marginal pricing policy - unlike with renewables who just pocket the excess profit - France will step in and use 50% - 90% of the profit to subsidise electricity charges.

    Hungary which generates ~50% of it`s electricity from nuclear, and are planning on increasing that to over 60%, do the same and their electricity is one quarter the price of Ireland`s. Poland will also own their nuclear plants and are planning on doing the same. Belgium are negotiating to nationalise their nuclear plants, and have changed their legislation on nuclear, planning to add a further 4 GW and do the same as France, Hungary, Poland and others.

    Under the marginal pricing policy renewables will never provide reasonably priced electricity. That it can be achieved with state owned nuclear is very much overlooked in these discussions



  • Registered Users, Registered Users 2 Posts: 30,004 ✭✭✭✭end of the road


    all of those countries support their nuclear by substantial subsidies.

    margional pricing and everything else is all backed up by subsidy.

    ultimately, it is subsidy that keeps electricity prices low and we don't really do that in this country, instead expecting the user to pay most of the cost.

  • Registered Users, Registered Users 2 Posts: 1,799 ✭✭✭bored65


    Why? We were sold a lie that renewables are cheap and clean

    Turns out they are neither

    We are about twice more expensive than France and about 20x more polluting than them after building 9GW of renewables in a country that needs about 5GW



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    Germany didn`t get a single bid for their 6 GW - 10 GW offshore offer last year.

    they are, so we weren't sold a lie.
    we still depend highly on gas and it is that that is of high expensivity hense needing much higher subsidy.
    it is our gas usage that is causing the polution and high prices.
    renewables will still require subsidy as well and that is not a big deal, they are still cheap compared to the alternatives.

    I'm very highly educated. I know words, i have the best words, nobody has better words then me.



  • Registered Users, Registered Users 2 Posts: 1,799 ✭✭✭bored65


    we are dependent on gas precisely because renewables need backup most of the time

    Due to their 30 and 10% capacity factors

    If you bought a cheap car that only worked a tenth to a third of the time forcing you to take expensive Ubers most of time to get to work you be well pissed off (and ripped off)



  • Registered Users, Registered Users 2 Posts: 30,004 ✭✭✭✭end of the road


    yes because we haven't installed the full amount of them yet.
    even then you will still need other sources like pumped storage and others but all together they will provide our energy needs.
    yes exactly, nuclear is like that car that only works part of the time and then requires you to not only have to get an expensive uber taxi, but to have that uber taxi on standby outside your door at all times because there is no predictive ability to know whether the car will work or not.

    I'm very highly educated. I know words, i have the best words, nobody has better words then me.



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    Problem is that nobody seems to know what the full installed amount will be, what these other sources will be and how much it would all cost.

    If you compare the uber taxi we use as backup for renewables + the 14.6% of electricity we imported last year to keep the volume down, to France, Sweden and Finland, their uber taxi drivers would be penniless and looking for another career.

    when you multiply a large number by zero, you still endup with zero

    Not a difficult concept, used to be taught in schools



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    Yeah, not a great look for them.

    Still, similar to the U.K. and Denmark not getting a single bid for a round of their offshore offerings, at least they now know who is really calling the shots.



  • Registered Users, Registered Users 2 Posts: 9,235 ✭✭✭Markcheese


    France has relatively cheap electricity, largely because of their legacy nuclear and hydro..

    Would France have cheap electricity if they had to build both from scratch today ? And for sake of fairness if they built an updated Westinghouse design (as the poles are doing) , which is pretty much what they did the 70s and early 80s , their nuclear assets work more efficiently because of their hydro schemes ..

    And remember, there's no benefit really from inflation over time , if the strike price for CFD is index linked +of course it is ..

    Even if you plug-in the most expensive of new reactors you still come well short of the trillion+ Germany spent and has nothing to show for

    Meanwhile loads of opposition to new gas plants needed for unreliable renewables

    Yeah, adding more gas will totally bring us cheaper electricity:
