    3 very interesting pieces of news.

    If they go ahead, I expect that the interconnectors could become operational by 2029? Greenlink took around 5 years from start to finish I think.

    Although Silvermines claims a potential 2026 start, that will probably slip and it will be 2030 - 2035 before it's operational.

    They are tapping into EU funding initially.

    Impressive, I present 6500-7000MW of wind at time of this post

    If all the limited budget is being spent on accommodating variable supply then the local infrastructure suffers…that is the point from which you wish to deflect attention.

    It's a complete straw man. If your company makes a bad business decision, it's not the fault of the government. Very simple. The German government made enough bad decisions about energy infrastructure, but your company's failings are their own.



  • Registered Users, Registered Users 2 Posts: 852 ✭✭✭gossamerfabric


    My company is the reason the local municipality is unlike others in Germany not broke but rather sitting on billions of euro. It is not their fault that the entire infrastructure of Germany has been steered toward bringing online intermittent supply while neglecting the grid which neither the company or the municipality can influence.

    Blame should be apportioned fairly at the feet of those responsible and those responsible are the Green movement and their apologists in Germany.



  • Registered Users, Registered Users 2 Posts: 3,538 ✭✭✭hans aus dtschl


    That makes no sense. It's like me complaining that I'm not making enough profit as I used to because of government policies. Your company - in your own words - made commercial agreements with its suppliers and its employees which are at odds with each other. This is absolutely not the government's fault.

    It scales from a technical sense but the minute you put the panels on a roof, the cost per kWh increases 3 fold on average according to Lazard. Installation and maintenance costs dominate as PV panel prices have declined so dramatically and working on/with individual domestic roof structures will always require more effort/cost. I think community-scale solar is a better bet if land is available. A single large say 2 acre field could hold as many panels as 150 domestic rooftop installations.

    IIRC it's a big open pit rather than at the bottom of a mine shaft.

    Using computers to search for possible sites :-

    https://re100.eng.anu.edu.au/global/ - generic mountain near a lake sites in yellow

    We found about 616,000 potentially feasible PHES sites with storage potential of about 23 million Gigawatt-hours (GWh) by using geographic information system (GIS) analysis. This is about one hundred times greater than required to support a 100% global renewable electricity system. Brownfield sites (existing reservoirs, old mining sites) will be included in a future analysis.

    Brownfield - https://www.sciencedirect.com/science/article/pii/S0960148124001782 - 904 sites in mining areas (“Brownfield”) with combined potential storage of 30TWh. But don't appear to list any here.

    There's half a million tonnes of salt coming up from 400m deep in the Carrickfergus salt-mines every year.

    True, but worth pointing out that for an individual, it can be well worth putting solar panels on your own roof, despite the higher costs.

    I was bored :)

    Lower reservoir location in Clogerane, Kerry. Good luck getting planning permission to flood here.

    https://maps.app.goo.gl/DsMhA543d7ZukHAf8

    But you'll have more luck there than flooding the good people of Kilgarvan in South Kirry. That mapping algorithm has no idea the people it is dealing with :)

    https://maps.app.goo.gl/rYk1xdaQ5T4B7mqQA

    This is the R584, or at least it was before it was turned into a lower reservoir. See that sign? It's for Gougane Barra, half a km up the road. Not going to happen.

    The amount of denial among the Green brainwashed is on a par with that of climate deniers. In an economy with an arbeitskraftmangel and scarce resources all being directed toward renewable sources of electricity they simply will not accept that if workers are busy commissioning green projects that the normal activities associated with grid buildout get neglected and wealth creating economic activity undermined.

    In other news the Dunkelflaute persists and it gets colder by the day.

    This morning at 9:30 solar in the UK met 3.2% of demand according to their dashboard. I didn't expect it to be so high, curious to see what it will get to by midday. (The UK have a very nice dashboard)

    You don't want to look at the eirgrid dashboard today. Ireland is probably the least energy independent country in Europe at the moment between coal, gas, wood oil imports along with interconnectors which could be turned off at a flick of a switch or snip of a cable.



  • Registered Users, Registered Users 2 Posts: 3,538 ✭✭✭hans aus dtschl


    What does your first paragraph mean? It seems to be an unrelated topic from my post? Did your employer make some bad business decisions or not? And is that someone else's fault or not?

    Also, here in Cork it's been sunny the last two days with a light breeze. Really lovely weather. My German's a little rusty but according to the helpful language lessons in previous posts, I'm drawing the - perhaps incorrect - conclusion that it's not Dunkelflaute here. Again though, not sure what relevance that has to my post which you quoted.

    Maybe you didn't mean to quote me?



  • Registered Users, Registered Users 2 Posts: 2,173 ✭✭✭Ben D Bus


    The Eirgrid dashboard is broken since yesterday afternoon. A pretty normal situation unfortunately. Even when it's available it rarely works fully.

    But yes your main point stands.



  • Registered Users, Registered Users 2 Posts: 852 ✭✭✭gossamerfabric


    I did mean to quote you. you are an apologist for a movement who couldn't even organise a piss up in a brewery if their lives depended upon it.



  • Registered Users, Registered Users 2 Posts: 3,538 ✭✭✭hans aus dtschl


    I'm not an apologist at all. I earn more money from gas and diesel fired electricity production than most people tbh.

    You just have a real knack of being wrong, by the looks of it :D !



  • Registered Users, Registered Users 2 Posts: 14,741 ✭✭✭✭josip


    If you want to expand on the energy independence topic, where does France gets the Uranium from for the nuclear that's providing 63% of its electricity at the moment?

    https://www.rte-france.com/en/eco2mix/power-generation-energy-source#

    And Belgium, Finland, and all the other European countries heavily reliant on nuclear power?

    Do German gas/oil fields keep its generators/transport going?

    I would be interested in seeing recent per-country figures for European Energy independence.

    That's all I really care about to be honest: the degree to which German dependence on Russian gas has made a mess of their economy was a real eye-opener for me. I know we have an integrated world etc but we need as much independence as possible. Greening is also important, obviously, but insulation from the whims of unpredictable regimes is absolutely critical.



  • Registered Users, Registered Users 2 Posts: 7,769 ✭✭✭plodder


    Wind is a no brainer here in Ireland. We have no conception of what 'blighting the landscape' means, compared to Germany, considering how under utilised the resource is here compared to there.



  • Registered Users, Registered Users 2 Posts: 852 ✭✭✭gossamerfabric


    …and yet I still have only a few kWh in the car over the last few hours. Charging nowhere near 11kW at the moment. Once they have trained up a few Azubis who aren't stolen away for green projects they might be able to roll around to improving the electricity network in the locality.



  • Registered Users, Registered Users 2 Posts: 852 ✭✭✭gossamerfabric


    "No brain"seems appropriate considering the disappointing contribution when it is needed in the cold of winter.



  • Registered Users, Registered Users 2 Posts: 14,741 ✭✭✭✭josip


    UK solar topped out at 11% of demand earlier. I missed the solar noon by 10 mins, might have been a few points higher then. Pushing for 2nd place in the Generation Mix. Admittedly it's a very peak point value on a perfect day for solar. But we're a lot closer to the winter solstice than the summer one. And these peak values are only going to increase in the coming years.

    I'd prefer to be able to have this discussion with respect to Ireland instead of UK/Germany. But in the absence of a working realtime dashboard for Ireland what can we do. The UK dashboard is really excellent, good granularity and minimal latency.



  • Registered Users, Registered Users 2 Posts: 2,418 ✭✭✭KrisW1001


    He was talking about Ireland, not Germany. And in that context, your assertion is nonsense. Ireland's highest wind availability is in the months from November to March inclusive. Peak wind generation in Ireland over the last 12 months was in December 2023.

    Our climate is very different to yours.

    Most data centres have generators as back up anyway ( I assume they're diesel and not natural gas ) ,in case of power cuts from the grid - so at peak times it's financially well worth their while to load shed , ie turn on the generators and not get power from the grid ..

    Probably batteries will be added to data centres for the same reasons - more available power and saving money ..

    Surprised they're not all putting solar panels on the roofs of data centres ,

    Currently the 2 largest suppliers of uranium,and uranium fuel are Russia and Kazakhstan, so make of that what you will , the US is largely ok because they uranium from Canada ,

    Australia is ramping up production quickly - that's likely to go to their Pacific allies , Japan and the US , maybe south Korea if necessary,

    So that kind of leaves Europe high and dry , France used to get their fuel from central Africa , that ship has sailed - for now ..

    So expanding nuclear isn't really that energy secure an option ,

    Having said that , any country that has nuclear facilities that can be got going again for a reasonable sum ( ha ha ,reasonable sum and nuclear in the same sentence 😉) would be foolish not to , there is fuel available - just not as limitless as was once though …

  • Registered Users, Registered Users 2 Posts: 9,060 ✭✭✭Markcheese


    Thats always part of the picture , it's an intermittent resource , obviously energy storage will help with short term blips of a few hours ,

    But beyond that it's plan B time , which is first the existing gas generators that we have, and any new gas generating facilities that need to be built ( prob open cycle ) , the interconnectors and any of the older less efficient legacy stations that are kept in readiness for a calm spell ,

    Apart from regular testing our generators periodically they never run. I am looking out the window at the chimneys from my seat at one of the datacentres right now. batteries exist in a datacentre purely to give a buffer to shut down the systems elegantly if power can't be restored.
