As of March 2015 Ireland has an installed wind power nameplate capacity of 2,230 megawatts (MW).〔http://www.eirgrid.com/media/All-Island_Wind_and_Fuel_Mix_Report_March_2015.pdf All-island Wind and Fuel Mix report for March 2015〕 In 2014, the year-long average capacity factor, or actual electricity generation from the entire nation's installed capacity was approximately 30%, with higher dependability in the gustier Winter months and lower in the Summer.〔http://www.eirgrid.com/media/All_Island_Wind_and_Fuel_Mix_Summary_2014.pdf〕 In 2014 wind provided approximately 700 MW of electricity on average, generating 19% of Ireland's average electricity demand, one of the highest electric grid penetration values in the world. Ireland's 188 wind farms,〔http://www.iwea.com/index.cfm?page=viewnews&id=130〕 are almost exclusively onshore, with only the 25MW Arklow Bank Wind Park situated offshore as of 2015. ==Previous milestones== , the island has 2,911 MW wind capacity. In 2014, 17.7% of Irish electricity came from wind, second only〔 to the 30% of Denmark. By 20 August 2013, Ireland had an installed capacity of 2,232 megawatts. The 2013 figure shows an increase of 232 megawatts compared to the figures reported on 24 March 2012. Depending on weather conditions the power was enough to supply 1.3 million homes in 2012. On 31 July 2009, the output from the country's turbines peaked at 999 megawatts. At that time, 39% of Ireland’s demand for electricity was met from wind.〔(Green Inc Blog on the New York Times Website )〕 On 24 October 2009, the output exceeded 1000 megawatts for the first time with a peak of 1064 MW. Once in April 2010, 50% of electricity demand was met from wind power. However, the wind generation capacity factor for 2010 was approx. 23.5%, giving an annual average wind energy penetration of approx. 11% of total kWh consumed.〔()〕〔()〕 On 19 July 2010 the Irish Wind Energy Association reported an installed capacity of 1746 megawatts, enough to power 753,000 households. 2012 capacity is more than four times the total of 495.2 megawatts in 2005. In 2008 alone, the rate of growth was 54.6%, amongst the highest in the world.〔(World Wind Energy Report 2008 )〕 Average 2013 output to 21/09/2013 is 486 Megawatts and Median 2013 Output is 393 Megawatts. Output can be as low as 3 Megawatts on a still day such as 12 July 2013 when a low of 3 Megawatts was reached at 9:30 am〔(Eirgrid Wind Generation Statistics )〕 which is 0.012% of the Rated Installed Capacity of over 2,200 Megawatts. As of July 2012, up to 14.8% of Irish electricity has been generated from renewable sources, up from 5% in 1990. Wind is the main source of renewable energy production, increasing from less than 1pc of total renewable production in 1995 to over 40pc today. On 7th January 2015, the output from the country's turbines peaked reaching 2,514 megawatts (63% of load), a new record.〔"(The Future Role of Wind in Ireland’s Energy Mix - Irish On-shore Wind In Numbers )" page 12.
