World’s first floating windfarm opens

They’re only tethered to the sea floor, but you still wouldn’t want to bump into one. The five turbines are 253 metres tall (of which 78m. submerged) and 720-1,600 metres apart, about 25 km.(15 miles) offshore. Will they throw the towel in if one floats away – or sinks?

First Minister Nicola Sturgeon has officially opened the 30 MW Hywind Scotland windfarm today (18 October), which is situated 25 kilometres off the coast of Aberdeenshire, and being operated by Statoil in partnership with Masdar reports Utility Week.

“This marks an exciting development for renewable energy in Scotland,” said Sturgeon. “Our support for floating offshore wind is testament to this government’s commitment to the development of this technology and, coupled with Statoil’s Battery Storage Project, Batwind, puts us at the forefront of this global race and positions Scotland as a world centre for energy innovation.”

Statoil’s executive vice president of new energy solutions, Irene Rummelhoff, said Hywind can be used for water depths up to 800 metres and will be able to open areas “that so far have been inaccessible for offshore wind”.

“The learnings from Hywind Scotland will pave the way for new global market opportunities for floating offshore wind energy,” added Rummelhoff.

“Statoil has an ambition to reduce the costs of energy from the Hywind floating wind farm to € 40-60 €/MWh by 2030. Knowing that up to 80% of the offshore wind resources are in deep waters (+60 meters) where traditional bottom fixed installations are not suitable, floating offshore wind is expected to play a significant role in the growth of offshore wind going forward,” she added.

  1. Scotland benefits and the rest of the UK pays through the nose.

  2. Saighdear says:

    Is the Fish effect just like the Gore effect? Been watching the gridwatch.templar site most of the day – under 2GW been produced all day ( over 3GW tonight as I write. Part time power for part time users ? All that expense – is Norway providing it for the Good of their Heart? Think not, WE will be paying Brit £s at reduced Xchange rates fro years to come. Great for the Balance of payments – Remember that in the News every month, years ago?

  3. “Our support for”, Nicola

    What you mean is the UK bill payer

  4. oldbrew says:

    Yes, we’re supposed to believe that ‘costs can be driven down’ with our own subsidies.
    Give me £10 and I’ll give you £5 back for free.

    Btw the turbines are from Norway and the floating bases from Spain.

    Update: The £190m cost was subsidised by bill-payers under the UK government’s Renewable Obligation Certificates.

  5. jolan says:

    The limit of 800m presumes that the turbines are tethered to the ocean floor. How far can they float horizontally?

    I’m just waiting for the next ‘unprecedented’ storm to see how this works out…can the British Navy re-deploy their minesweepers as wind farm debris-sweepers to clean up the mess? and will Statoil’s insurance cover the cost for UK taxpayers?

  7. oldbrew says:

    Statoil says: ‘Linked to the Hywind Scotland project Statoil and partner Masdar will also install Batwind, a 1MWh Lithium battery storage solution for offshore wind energy.

    Battery storage has the potential to mitigate intermittency and optimise output.’

    One megawatt hour won’t do a lot, maybe buy time to find another power source when the wind drops?

  8. Tim Hammond says:

    I know Sturgeon speaks utter b*llocks most of the time, but what “race” does she think she in?

    For taxpayers, it is far better that Scotland waits until the cost of generation is as low as possible before putting new technologies in place. Being first in some delusional race simply results in higher costs for everyone.

  9. oldbrew says:

    Tim H: costs are subsidised by energy bill payers, not from taxes.

    They used to be in a wave power race. How’s that going ☹

  10. oldbrew says:

    Date: 18/10/17 M J Kelly, Department of Engineering, University of Cambridge, UK

    The agreed wholesale price of the Hornsea energy over the next twenty-five years is £140/MWh. Even assuming a very generous load factor of 50%, Hornsea’s lifetime revenue would be about £20 billion, suggesting a ratio of revenue to cost of 6:1 (reduced further by any maintenance costs), still barely half the average value that prevails in the global economy, which is more than 85% fossil-fuel based.
    . . .
    There is a lot at stake in the choice between cheap fossil fuels and expensive renewables.

    Slow the economy or not – who decides?

  11. Stop the wind and set the world on Fire!

  12. ivan says:

    It will be interesting to see how they perform in real world conditions.

    Will the blades fail through fatigue before the bearings give out or will they be shut down every time there is a little rough weather?

    If they get a 25% usage factor out of them it will be one for the books and I reckon on them maybe reaching 28% of nameplate output on a good day.

    Ah well Statoil et al will get their money even if it is only the little people that are paying for this fiasco.

    [reply] And 90% of them won’t even be living in Scotland

    Might be some interesting reports as Brian drifts through.

    “If they get a 25% usage factor out of them it will be one for the books and I reckon on them maybe reaching 28% of nameplate output on a good day.”

    I think you are wrong there, they should get close to 100% on a good day, which is offset by the 0% on a bad day, ending up with 25% to 28% overall.

  15. oldbrew says:

    The claim is that taller turbines further offshore will get more consistent wind and stronger wind.
    This £190m. ‘experiment’ should be able to test that.

    And for the next trick – kites…

    Kite Power Systems Moves To New Glasgow Offices
    Wednesday, October 4th, 2017

    KPS’ power system features two kites which fly up to an altitude of 1,500 feet. Both kites are attached by tethers to a winch system which drives a generator as they spool out, thus producing electricity for the grid. This technology has the potential to transform the global onshore and offshore wind generation markets, as it is cheaper to manufacture and requires less construction and installation materials than conventional wind turbines (See Notes to Editors).

    As the only UK company active in the high-altitude wind power sector, KPS is currently flight testing its 40kW system at West Freugh and its latest 500kW demonstration model is being manufactured and assembled in Dumfries.

    West Freugh military range kite power scheme approved

    The RAF left West Freugh in 2001

    YouTube should be getting some rather spectacular videos down the road of the debris field when these things meet Mother Nature
