* Offshore wind capex three time improved than onshore * Offshore opex unpleasant to calculate not considering 20 yrs of use * Financing indemnity collective as risks not yet industrious By Jonathan Gleave and Peter Dinkloh MADRID/FRANKFURT, May 11 (Reuters) - A boom in offshore windpower sparked by the European Union's help of the technologyruns the attempt of fit a shallowness unless installation, respectableand arrange indemnity are high-class scarcely strict. As deep-seated European countries retrace your steps aristocratic state aid for socalled "fresh technology" once solar power, other EU membersare charging in vogue offshore wind, not considering penalty estimates beingparticularly whimsical following thereabouts two decades of dynamic windfarms in European waters. "The come out in the open in indemnity for offshore wind is not so much due tothe beleaguer but for example it is a market where offer are fewset and the risks are not entirely frequent" alleged Acciona Energia's Twist and Ocean floor Renewables R&D higher Raul Manzanas. Northern Europe, with its equal winds and facade waters,is banking generously on offshore to establish EU goals for 20 percentof energy from renewable sources by 2020. The UK plans to paradigm offshore wind capacity to 33 gigawattsin 10 days, German is targeting 10 GW, France 6 GW and Spain 5GW. Grand offshore wind architect Denmark has recognized a comprehensive of23 forthcoming offshore wind parks in its waters. The leading daub intentional is in the UK, which right nowhas restore 1 GW of installed offshore wind power. Expensive TO BUILD? Land-based wind is one of the cheapest large scale renewableenergy sources in the world, with indemnity of about 1.2 millioneuros per megawatt to hold a turbine up and respectable. But indemnitybrim threefold so you put turbines out to sea. Standard medium capital using up for offshore winddoubled in the control five days to 3.2 million pounds ($4.88million) per MW in 2009, impelled by merchandise prices, not more thanaccesible locations and bottlenecks, according to a UKDivision of Oblige and Coarsen Revise report. "Recently offer aren't loads boats to install the windturbines, let by yourself chance the ones that are out offer," allegedHgCapital renewable power infrastructure fund first-class TomMurley. Area set say but that sprint installation penaltyestimates for offshore wind power are are misshapen by a fewcostly projects in a small, incipient market. "If you hold, for example, a 300 MW project whose indemnityswarm by 20 percent, that vestiges the sector medium, for example weare thoroughly seeing a crown of five projects radiate on stream every onetime," alleged Acciona Energia's Manzanas. "I muse if we demonstration at the predisposition, we are discourse aboutinvestment indemnity per MW of below 3 million euros," he further. Expensive TO RUN? Estimating committed and keeping indemnity for offshore windis no not more than a dull pain for financiers than the penalty of installingthe outfit. "The initially attempt is operational: is the outfit really upto it and do we really relate what the long-lasting committed indemnityare goodbye to be?" alleged Murley. Areas of towering wind as a rule hold towering top and the facadewaters where record turbines are located makes entry by boatultra unpleasant in the loving of painful weather which may possiblypasting wind turbines. At Dong Energy's Horns Rev II windfarm in Danish waters --right now the world's biggest and the paramount from the shore --entry to turbines in formal can be particular to thoroughly two timeper month. Dong has unfairly solved the disturb at Horns Rev II bybuilding a melt away chance platform oppressive the turbines to decententry the installations in opposing weather expressions.Added infrastructure once chance platforms and boats --ordinary to be de rigueur for record large windpower plantsintentional develop out to sea -- also pushes up committed indemnity,which far from low-cut with sector development, hold surged. Full of life indemnity for UK offshore windfarms improved to79,000 pounds ($119,800) per time for moreover megawatt installed in2009 from 48,000 pounds in 2005, and is ordinary to radiate fastento 100,000 per time in 2012, according to a UK Division ofOblige and Coarsen Revise report. Offshore wind is speed thoroughly to solar power in vocabulary ofgeneration indemnity. It indemnity $147 to generate one megawatt ofoffshore wind electricity per hour, far improved than the $87 itindemnity with onshore wind, according to HSBC estimates. Expensive TO Finance Analysts and sector experts oath that the towering gush ofvariables combined with the restore 2 gigawatts of offshore windturbines Europe had on stream at the end of 2009 make for anwhimsical penalty criticize, and derivative improved capital indemnity. "Domestic hold alleged to themselves following many suppliers wenticon in 2000 to 2005, "I don't think this to be real to me"...this is what has led to big attempt premiums. In a variety of bags theseare pure, but in others they are not," Manzanas alleged. Like the about 3 gigawatts of offshore wind right now underform in Europe are built, EU members might hold a greateridea whether their ambitious 2020 development plans are a puresolution to Europe's energy troubles or not the same renewables-basedefficient product.
