    The source is one thing, the framing and general use of rhetoric shows an agenda on the part of the writer.

    Falling Irish wholesale electricity prices were the principal driver of the 1% month-on-month fall in the Bord Gáis Energy Index during December. Increased wind energy, which met a record 24% of the total electricity demand in December, combined with a reduction in electricity demand due to the mild weather, resulted in wholesale electricity prices dropping by 5% month-on-month.

    Wind forecasting is fairly accurate. And grids already have reserves to cater for the largest generating unit going off line anyway. The UK gets 5% of it's electricity from wind. Unpredictability means that 9% of the operating reserve was used for it, and the rest was used to cover the "dispatcable" stuff.

    Overall wind provided over 1,000 times the power that was used to cover it's "intermittancy"

    http://www.gizmag.com/uk-national-grid-wind-data/28046/
    For the 23,700 gigawatt-hours of electrical energy generated by wind in the UK between April 2011 and September 2012, only 22 GWh of electrical energy from fossil fuels "was needed to fill the gaps when the wind didn't blow,"
    ...
    Table 2 of the report shows the energy provided by the National Grid's Short Term Operating Reserve, and how much of that was due to wind energy output being lower than forecast. Of the 246 GWh provided by the Reserve for the same period, 22 GWh are thought to be due to the wind not blowing as forecast.

    Is Ireland heading this way - Germany being bankrupted by renewerable energy

    You didn't really mean bankrupted, did you. You just threw that ludicrous exaggeration in the hope that someone feeble minded might actually believe it. Isn't that right?

    Like many countries, once promising advances in nuclear technologies have suddenly taken a backseat after Fukushima. Unlike America, Europe has not been able to transition to natural gas,
    They are promising technologies, they've been promising then for decades without delivering. "But this time it will be different". EDF still hasn't completed one of their current EPR reactors.

    We have gas. We all use gas. Coal is cheaper though, but it's used for base load. We all use gas to match supply and demand.


    http://www.bloomberg.com/news/2014-01-03/german-power-costs-seen-dropping-for-fourth-year-energy.html
    Wholesale power prices in Europe’s biggest economy plunged 32 percent since 2010 amid record wind and solar output and the weakest demand in four years. The cheapest coal since 2009 is spurring utilities to keep building plants burning the fuel. EON SE (EOAN) and RWE AG (RWE), the largest generators, will report lower profit this year, according to analyst estimates compiled by Bloomberg.

    ...
    Year-ahead electricity prices fell 19 percent to 36.80 euros ($50.30) a megawatt-hour in 2013. The contract closed at 35.90 euros yesterday, its lowest settlement since March 2005, and at 36.15 euros today, according to broker data compiled by Bloomberg.

    ...
    Generating capacity will expand by 9.4 gigawatts this year, equal to 5.3 percent of current supply, according to Energy Brainpool GmbH & Co. KG. Renewable capacity will rise by 5.1 gigawatts and coal plants will supply most of the rest in their biggest expansion since at least 2000, the Berlin-based consultant estimates. A gigawatt of electricity, or 1,000 megawatts, is enough to power about 2 million European homes.
    ...
    EON, RWE and Stockholm-based Vattenfall AB, the three biggest utilities operating in Germany, plan to shutter more than 16 gigawatts of unprofitable generating capacity in central-west Europe in the four years through 2015, company filings show.
    So yes there is more coal but there is also less coal. A lot of the new coal plants are replacing older more inefficient ones.

    No details on which plants are closing but it's unlikely to be renewables
    http://gastopowerjournal.com/technologyainnovation/item/2851-german-regulator-approves-closure-of-51gw-of-generating-capacity

    Jan 16 – The German energy network regulator, Bundesnetzagentur, has approved operators' requests to close 16 power plants with a combined capacity of 5,092 MW.

    The plants are located mainly north of the river Main, where closure impacts less on security of power supply than in Bavaria and Baden-Württemberg – the states most impacted by Germany's nuclear exit.

    So what does this all mean for the Irish markets ?

    Dropping whole sale prices must make wind farms less attractive to build

    The reduction on the emphasis on CO2 reduction by the EU must also have an impact

    15 year contracts by the Irish government to wind farm operators would have to some how price in these market variations (somehow)
