Because the energy in the wind obeys a cube law (2 x speed = 8 x energy and also sadly 1/2 speed = 1/8 energy) The annual average ends up looking like a number of unpredictable short term spikes smeared over a grindlingly low base value. As memory serves me - the capacity factor (i.e. the 24%) is only ever reached or exceeded in UK for less than 40% of the year. The headline rating is very rarely reached (if ever - a maximumum of a few hours a year)BilloTheWisphttps://www.blogger.com/profile/16221663524948086557noreply@blogger.comtag:blogger.com,1999:blog-3508346572086151757.post-66309415041695212732014-01-14T12:33:14.641+00:002014-01-14T12:33:14.641+00:00@ Ed P - not exactly.

Or look at it another way - in a stiff breeze it might actually chuck out the full rated amount, in a light breeze it could be a few tens of KW's, or when it's calm nothing at all!<br /><br />There is another crafty wheeze being employed - since the subsidies paid out are greater per unit for sub 500KW turbines, the investors are now installing standard 2MW units, but limiting the maximum output to 500KW, knowing they will be running nearer to this figure for more of the time, and thereby maximising the amount of subsidies they receive...microdavehttps://www.blogger.com/profile/01352078582764696261noreply@blogger.comtag:blogger.com,1999:blog-3508346572086151757.post-25041536667331553762014-01-14T11:41:00.136+00:002014-01-14T11:41:00.136+00:00From everything I've read in the last few year...From everything I've read in the last few years, wind turbines normally go tits-up after only 5-7 years because of gearbox trouble. <br /><br />In the USA this problem is so bad that a Government-sponsored agency ("Gearbox Reliability Collective" (GRC), part of the NREL, National Renewable Energy Laboratory) has been looking into it since 2007 and they <i><b>still</b></i> don't know for sure what causes it, let alone have any clue as to how to fix it.<br /><br />For more info, see:<br />http://billothewisp.blogspot.co.uk/2013/12/wind-turbines-ghost-in-gearbox.html<br /><br />This website also has interesting articles for anybody interested in the damage being caused to the seabed by offshore turbines.<br /><br />Mike.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3508346572086151757.post-16138294050919219872014-01-14T09:18:23.710+00:002014-01-14T09:18:23.710+00:00My accountant is courting the 'contractors'...My accountant is courting the 'contractors' who work in the Walney offshore farm as they are loaded, pretty dim, scared shitless of HMRC whicg apparently makes them an ideal customer as they are all self employed.<br /><br />Best of all though is those in the 'maintenance game who spend most days fishing or bobbing about in boats due to the weather and the shed load of elfin safety that prevents them from working if a butterfly flaps its wings. <br /><br />Off topic but highly relevant (is that possible?)<br />Do have a read of this most excellent PDF.

I'm Master of a coastal tanker, have watched these wind farms sprouting up around the coast and seen what proportion of them aren't working on even a moderately windy (what you might call a good power generating) day.
