    Oh and by the way, the new nuclear plant at Hinckley Point here in the UK will receive a guaranteed price per kWh when it begins generating.
    and that price is twice the market rate , index linked for ages

    and it'll only provide baseload power because nukes have to be keep running most of the time at high power for technical reason and to break even on their huge construction costs

    The point I think Fabo may have being making is that youd expect wind to REDUCE the need to import fuel.

    So its reasonable to wonder why we are increasing imports of fuel if we are adding more renewables to the system.

    Im not saying wind is causing this - but its a valid point I think

    I havn't seen the figure, might it be a percentage or an actual figure. Remember 40% of fuel is used for transport

    30% of power came from renewables this week , 20% this month

    you can compare CO2 emissions vs. wind easily

    And to be fair the dashboard figures do seem to show a reduction in C02 intensity per kwh when wind is on the system

    From memory it was at 570/600 at around 200 MW of wind on the system.

    And around 363 with 2,000 MW of wind production

    I may be wrong with those as im working off memory

    Lets not forget the fuel used for heating and for raw materials. Also there are the grey exports of vehicle fuel to the North due to excise differences and people on the border buying it on the best side.

    Climate also matters. It's a lot warmer than some recent winters.

    There was a fair bit of curtailment during the week. The SNSP was hovering around 48% most of the week with wind output close to Max capacity. The peat plants were running. These are really the only stations that use domestic fuels.

    I'm always amazed to see how much the price increase during peak hours. If we could sort that out price would drop big time

    Since the governments brain fart on wind energy and general interference in the energy market in the last 15 years we have seen the retail cost of power in this country go from less than the EU average to the 4th most expensive. We now have an installed energy system that is double peak demand. And given the plans of Eirgrid,SEAI etc and the rest of the wind cheerleaders, this situation will continue to deteriate into the future.

    Renewables aren't the only factor. If domestic production of another fuel goes down or overall demand goes up, our import dependency will go up. You may not be blaming it on wind but I'll be waiting for someone else to shortly.

    The SEAI report explains some related trends:

    The decline of indigenous natural gas reserves at Kinsale is also indicated by the growth in imported natural gas in the latter part of the decade. Coal imports have remained stable over the period, reflecting the base load operation
    of Moneypoint electricity generating plant. In 2013, oil, gas and coal accounted for 55%, 30% and 12% of net imports respectively.

    Other contributions to the increased import dependency in 2013 were:

    • Coal imports were up 11% to 1,485 ktoe
    • Oil imports were up 4.1% to 6,761 ktoe
    • Renewables imports were up 44% to 114 ktoe
    • Electricity imports were up 413% to 182 ktoe.
    Countering this was a 3.4% fall in natural gas imports to 3,717 ktoe.

    Are you taking about costs or prices? You seem to be mixing then up.

    By the way, funny line on government interference in market in the last 15 years. You might want to look up the history of EU energy market liberalisation, which started more or less 15 years ago.

    Did you note in the SEAI report that all power delivered via the interconnector comes CO2 free

    http://www.seai.ie/Publications/Statistics_Publications/Energy_in_Ireland/Energy-in-Ireland-1990-2013-report.pdf

    page 24

    Imported electricity is also considered zero carbon from Ireland’s perspective under the Kyoto Protocol as emissions are counted in the jurisdiction in which they are emitted. This resulted in the carbon intensity of electricity dropping by 48% from 896 g CO2/kWh in 1990 to a new low of 469 g CO2/kWh in 2013

    and do you notice that the IWIC http://smartgriddashboard.eirgrid.com/#all/interconnection
    runs at typical 200 to 500Mw import -

    so that's 15% to 25% of Irelands average demand (2000->4000Mw) coming CO2 free by magic.

    What's funny - is that some of this will be CO2 free as its from Nuclear (which typically cannot be ramped) but some of it will be from coal stations which hate to ramp

    Although they are technically reporting the numbers correctly its this blurring of the detail which undermines the value of a report such as this.

    Apologies if this has been posted previously as it's from 14/10/14, but I am discovering a report today from the Irish Academy of Engineering that I thought I would share here. I think it is relevant, and I will quote some snippets from the summary. (full report available on their website).

    I think I have seen mentioned bias within this group before, but all I can see are members' previous occupations and not really anything current that could imbalance their views, please correct me if you think they have a current interest in producing a biased report.


    Implications of continuing with existing Energy Policies
    http://www.iae.ie/publications/publication/iae-bulletin-no-4-implications-of-continuing-with/
    Continuing with the existing policy and related conditions is likely to have adverse economic
    consequences.
    Commitments entered into in 2007 relating to the amount of renewable generation on the
    Republic’s electricity system are driving current policy. This could lead to the addition over the next
    decade of more than 3,000MW of Windpower onto a system that has already excess capacity.
    This approach is not economically viable in view of the following:-
    ...
    o There is no demand or supply security requirement for new power plants over the next
    decade.
    o Irish energy prices are already high compared to the EU average.
    o The 2007 targets reflected the apparent buoyancy of the economy at that time and are not
    relevant in the present economic situation.
    o Windpower and Solar are currently expensive forms of energy due to high capital costs and
    intermittency. In particular it is an expensive way of avoiding CO2 emissions, costing in
    excess of €75/tonne of CO2, as against a current market price of under €7.
    o Existing windpower plants and new units under construction with other forms of renewables
    are adequate to comply with the 2020 EU requirements for renewable energy in the
    Republic (recent Academy reports contain proposals).

    ...
    Making a fundamental change in Irish energy policy reflecting current
    economic circumstances is a major issue.

    Capacity is not the issue.

    emissions and fuel cost are, otherwise we'd just use oil for the turbines and coal for the steam plant

    a lot of the recently installed capacity has been commercial gas and it was never a secret that ESB/Airtricity etc were looking towards wind/interconnectors

    the question is not why did we keep adding wind, it's knowing that wind was coming why did investors invest in gas too

    And how do you propose we power the country during extended periods of light winds?? - it was Eamonn Ryans brain fart that has led us up this dead end path of wind energy at any cost. We will allways need gas power stations as it is a reliable low CO2 energy source. The NCC are the latest body to question the states increasingly nonsensical energy policies

    The ESB in their recent submission to the Dept of Energy Green paper have called for an end to supports for the likes of wind as there is more than enough on the system already.

    It's a very cryptic reply.
    It seems they are all highly qualified with a lot of experience ? :confused:






    CM as they state the currently happening and established renewables as of October 2014 are meeting requirements for 2020.
    Why over inflate capacity then, with all the financial, environmental, and societal costs associated ?

    They do mention improving security re gas supply in another report. Their suggestions relate to establishing a stock to the amount of 20% of yearly gas needs iirr.

    There are a number of other suggestions, such as district heating, etc...

    Alternatives to more wind turbines. Fancy that ...
    It's simple really, and still time to change policy. They're recommending it, and also mention a recent review by EU commissioner with similar warnings. Must find out more about that.

    No there is a big difference. Engineers Ireland has 24,000 members and represents the engineering profession in Ireland. All of its members have to engage in CPD to maintain membership and of course be working out available to work as an engineer.

    The Irish Academy of Engineering has 145 members, most of whom are retired. They are the old guard. If you look up the two bodies' views on energy policy, they are quite different and the nature of the two organisations helps explain why.

    I have no idea who is saying we have enough renewables to meet our 2020 target or on what basis because it's total nonsense. We are one of the countries considered at risk of not meeting our target.


  • Registered Users Posts: 6,700 ✭✭✭Mountainsandh


    That's more informative, thanks.
    I'm trying to find clear estimates in the EU commissioner's reports here http://ec.europa.eu/energy/efficiency/events/2014_energy_efficiency_communication_en.htm

    It's time consuming, and there are very few country specific estimates, but it's interesting enough.


    What is very obvious is the contrast in policies and EU recommendations to what Ireland has been "doing" (as in : action) so far to achieve targets.

    The EU commissioner makes it clear that a wide ranging set of measures will achieve targets (or close : within 1 or 2% estimate). Every report that I read has lengthy sections that I find myself scrolling through, simply because here in Ireland, as this thread illustrates, the overwhelming emphasis is on wind energy sorting out all problems.

    This annex illustrates other measures taken by EU countries and their impact, it is a little glimpse that for once is nominal : http://ec.europa.eu/energy/efficiency/events/doc/2014_eec_ia_adopted_part3.pdf

    Meeting the targets does not and should not, as advised by EU commissioner, rely on one aspect of energy production. It is a mistake.
    The old engineers did not pick district heating, and other alternative measures out of a hat, these are EU commissioner recommendations to achieve targets.

    I will spend more time reading this week-end (if I can squeeze it in !), and post here if I find nominal estimates of what countries will achieve targets to what extent.

    Edit : it would be great to know whether there are non anecdotal, official Irish reports which state Ireland is not going to meet targets.


  • Registered Users Posts: 1,691 ✭✭✭fclauson


    The issue is Ireland never completed a proper NREP (National Renewable Energy Policy) - that's the whole Pat Swords vs EU Commission etc case

    Ireland went wind wind wind wind with very little else.

    For example Electric Ireland have just pulled their PV feed in tariff for new domestic entrants. There is next to zip support for anything renewable bar wind.

    I believe (and the evidence is starting to show) a mass retrofit program is a better route cutting C02
    a) it draws on skills in the work force (with some training) and employs people
    b) cuts peoples heating bills - For ever
    c) moves people out of fuel poverty (the PSO levy is moving people into fuel poverty !!)
    d) is something you can do yourself or employ a professional

    If back in 2004 or earlier the government had done a proper energy review and made the decisions to move to only permit Passive Houses or even highly insulated houses we would be in so much a better place across the country rather than now we have a pile of houses which are amazingly energy inefficient, wind farms going up which are highly inefficient (it costs them €70+ to save a ton of C02 rather than the market rate being around €7)
    and we are failing to meet our C02 targets

    So do we have enough wind - yes - because (and back to my very very first post) when the wind does not blow we need a backup.

    In Oct here was a instance where the entire Irish wind fleet produced -3Mw (UK was also very low so don't come the interconnect at me)

    We need to sit down and work out what needs doing and what is best for the Irish citizen

    Great post Francis

    Part of the difficulty with wind - isn't so much the turbines themselves - but the fact that we are planning energy on its own COMPLETELY separately from everything else.

    Moving to the low carbon economy or decarbonising - isn't just about how many wind turbines we can fire up - but also how we will live in the future - how we live and how this is planned will hugely impact on our emissions.

    For example - and being pro Agri this pains me - but if you reduced cattle numbers this would reduce emissions.

    If you improved the energy efficiency of BOTH new and existing homes YOU REDUCE the amount of energy needed in that home - which is fantastic especially with heating.

    Actually this applies to all buildings - not just homes.

    Really we need to work towards getting to a point where energy planning AND how we live - plus industries for now and in the future - and so many aspects of our lives get planned together.

    The other aspects that need looking at - include......

    One off houses are blamed as a challenge to wind energy planning in Ireland - a fair point - however two things are being over looked

    Firstly - where are the people in the one off houses going to live in the future - bearing in mind one off houses are seen as negative to the environment in general - not just wind energy planning in general.

    Secondly - if the answer to where people will live is - "in their current one off homes" - how do you ensure the wind energy is going to be the trouble free neighbour that wind energy claims it will be. And if the answer is - we could move people out of their homes - where will they go - and how do we plan the new living solutions for what would be ex one off house residents.


  • Registered Users Posts: 5,791 ✭✭✭Old diesel


    I think we should look at our energy planning with a different mindset

    Some possibilities going forward......

    1) Residents feel negative about energy production solution in their area - I wonder should the aim be - to get to an operational scenario with projects where residents are VERY PLEASANTLY surprised with the end outcome - regardless of what that would be.

    2) Wind energy says its solutions are problem free - others disagree - but regardless - my PERSONAL mindset if I were planning wind projects in a community - would be to ENSURE the wind energy solutions im planning are in fact trouble free for residents. This REALLY shouldn't be a problem if wind energy is as problem free as its supporters and promoters claim - for residents.

    3) designing everyday living solutions that work for residents very well - but that these could be co designed with energy solutions - which may include wind - that deliver on the goals of renewable energy - and driving towards decarbonisation. In short plan BOTH living in the future - and energy together - don't just plan one and completely overlook the other.

    finally - design the communities of the future - and the ENERGY SOLUTIONS of the future plan and design them together so they work great together - think of the people as being the wheels of a car that move the country forward - and the engine as being the renewable energy.

    My thinking being - all the parts of a car are designed to work together - we need the same mindset planning Irelands future communities AND its energy production.

    Im trying to be constructive here btw - so if im coming across as anti wind - I apologise - as while im not a lover of wind - I more intend the last post and this one to be constructive in moving forward

    There are no real plans for new safer mini nukes.

    Hundreds of safe mini nukes have been used by the Navies of US, UK and France since the 1950's.

    They are a shining example of how nuclear power could be if you didn't have to worry about the cost.

    However no one's commercialised the technology, and lots of commercial nukes haven't reached the safety levels of western naval reactors.


    You could make the comparison with supersonic aircraft. The military has had them for ages, but they haven't exactly taken off for public transport.


  • Registered Users Posts: 6,700 ✭✭✭Mountainsandh


    The storm of objections has pretty much been ridden enough to ensure Ireland meets its targets.

    It can be done, but for such a humongous step to be taken, information and communication need to be honest and comprehensive.
    People are not idiots.

    If there is a possibility that one nuclear station may make a massive difference to the lives of people in Ireland, and everyone is adequately informed, I think people will give it due consideration.

    I hate the way it is always established as a given in Ireland that people are idiots who will reject any new proposition outright, or who will not have the capacity to understand a complex situation.

    It happens in the medical system all the time, it happens in the case of abortion at the moment, gay marriage, you name it.
