    Anybody know if there's any subsidy for the construction of large (1 MW or so) onshore wind turbines? Or offshore, for that matter. There are various forms of subsidy for their actual electricity output (via guaranteed prices and ROCs) but are there any others? My understanding is that there were years ago but they're long gone but it'd be handy to have a proper reference.

    There may be regional grants, I think there are around here.
    Can give you a number of someone who may know for sure.

    Doubt it - the new Env Sec confirms that disparagement of onshore wind is a Tory vote catcher, as well as a support for their big-biz nuclear mates. Big new Cornish scheme just turned down.

    I must say, much as I like all the elegant turbines I see as I trundle down the A30 (means you're really in Cornwall now), there has to be a limit - miles of nothing between isolated wind farms. If they were on every Cornish hilltop, that would be a blight.

    Cornwall is a special case, as there is a lot more electricity used in Cornwall then generated in Cornwall. The cables feeding Cornwall are also mostly at capacity and very expensive to upgrade.

    PV does not help, as the peak demand is on cold winter evenings.

    OK, but any authoritative sources of information on subsidies other than those supporting the price of the electricity produced?

    There is a “hidden” subsidies/charge in that the network connection charge takes into account the effect on the destitution network capital spend needed.

    So in an area with lots of Wind farms but low depend, the connection charge will be more, as the additional wind farms make it more likely that the network will need upgrading to cope with the additional generating capacity.

    That makes sense but it's hardly a subsidy - just the wind farm operators paying for connection at a price related to the actual cost of having a distribution service provided to them taking into account the other grid users in the neighbourhood.

    Relatedly, there's also the payments windfarms get when the grid turns down the electricity they offer if the grid doesn't have the capacity to distribute it but a) that applies as much to other producers and b) it's not really a subsidy, just a matter of contractual agreement.

    Background is that I had an argument with somebody about this. I'm going to avoid that particular person in future but there are a lot of people around here who are anti-windfarm and I want to be sure of my facts and sources if it comes up again.
  1.  
    In all fairness I would agree in part that all of the new EWT 500kW turbines are harming wind power. In my opinion the individual turbines spread all over the place has a greater impact visually than good sized windfarms.
    I am very pro wind power generally as I am linked to the industry.

    I also have a major issue with turbines that are engineered to produce 900kW being limted through software to get the FITS payment. In my view that is just totally wrong in every way. My solution would be to let the owner get the 500kW rate and for power above the 500kW limit the rate drops away.

    Limiting peek output also reduces connection costs and may not have that much effect on reducing total output depending on the site. After all we do need power on days that are not blowing a gale.

    Wind power seems to stir up a lot of emotions, and I mean in the emotion rather than reason way. Given the urgency of the need to cut GHG emissions I think most of the objections to wind power are at best frivolous and at worst immoral. In 2040 when we discover we've put enough carbon dioxide into the atmosphere to commit ourselves to massive destruction of the natural world, increase in natural disasters, crop failures etc no one is going to care whether they might have been able to see a wind turbine out of the corner of their eye from their upstairs window...

    That's a prime case of unintended distortion via incentive/loopholing - and one that government could readily mend.

    It's so simple a story that the press could easily run it - the scandal that government squanders the national benefit that should arise from the public spirited 'suffering' that huge turbines impose on communities.
  2.  
    Fostertom- Exactly but not quite so much "suffering" I hope.

    FIT limit at 500kW is just wrong in my view. I don't blame the owners but the system is twisted.

    ringi- That is when capacity factor becomes more relevant. Any turbine not running in the 20's at the very least is poorly sited and should not be there at all. The sites I manage run at around 33% capacity factor. Fairly good for the UK. If a turbine is erected to generate power from the wind it should in my view be positioned to take full advantge of high and low winds. Very low wind sites should stick to PV or tidal/hydro.

    Wind does not work in every loaction across the country. People also tend to think that turbines shut down in high winds all of the time for safety reasons. The modern Enercon turbine will run in 35m/s, roughly 70mph wind speed. Now that is a windy day.

    Yes, but what about the non-electricity related subsidies?
    • CommentAuthorEd Davies
    • CommentTimeOct 28th 2014
     
    Reason I'm asking, by the way, is that I had an argument with somebody yesterday. Like many he is very anti-wind (and something of a GW denier - it's happening & human caused but doesn't matter as it'll have no significant effects, apparently) so can't see the point of wind. To be fair, if AGW wasn't a problem and there was an unlimited supply of gas in politically acceptable places he'd have a point. Anyway, I'll be avoiding any discussions of this sort of topic with him in future but if anybody else insists that wind farms are subsidized other than for the electricity produced I'd like to be a) sure of my facts that they largely aren't (any more) and b) have some sort of reference to back that up.

    Steamy's hypothesis that there are regional subsidies is at least plausible and relevant - be interesting to see if anything comes of his minor enquiries on the subject.

    Spoken to a couple of people (in England), and there are now no grants for capital expenditure. Not even regional.
    It was suggested that the best method for funding (for smaller turbines, less that 10 2MW) is community finding and initiatives.
    They may get funding for other areas of the installation, say training and education/visitor centres.

    If you are on the FITs (tends to be for the smaller stuff) then you get the money on generation. You can enter the auction market, but are more at the mercy of the weather and demand, but does pay better overall. But that is really for the large developers who can afford to 'buy in' at 20p/kWh if they need to (basically domestic rates).

    There has been a fair bit on the radio today about our generation (because we are low on spare capacity again).
    What annoys the hell out of me is when they say that RE is unreliable i.e. the wind don't blow and the sun don't shine.
    These two are forecast very well (most of us know when it gets dark, well we did last week). They give the impression that one cloud or a bit of a stiff gust kills all RE generation completely.
    It is also worth mentioning that the woman that runs the National Grid says there is not a real problem at the moment, it is tight, but not fatal. She only had a few minutes to explain that they are negotiating with generators to run in stand-by mode, large users to reduce load. It is not as if we only have one power station and if that goes wrong we are snookered.

    Wrong.
    The bulk transport down here is excellent. Plenty of capacity, part of the reason there is a 900 MW gas plant in Plymouth. The end of the line at Hayle is especially robust as there used to be a power station there, they never built the nuclear one though, it is to radio active down here to start with. But the Wave Hub (what a joke) can easily supply to it (but that is just a testing ground).
    There is some trouble with over capacity on some tiny rural cables and transformers, but WP do a very good job at upgrading where they can/need to.

    If I recall correctly the issue with Cornwall is the connection to the “English” network and hence up to the midlands power stations. I believe that the Plymouth gas plant was one part of reducing the problem.

    For many years no one could get planning approval to build new power stations in Cornwall, hence the flow got very unbalanced. So anyone wishing to generate in Cornwall got a very good deal on connection charges.

    You could point out to this bloke that the very large coal/gas/nuclear generators get paid to shut down too, and get paid more when capacity is tight. Small scale RE gets the same no matter what.
    Once away from the small scale stuff (should be called government backed financial services), all the big boys play by the same rules, it is what the CfD was all about. The wholesale price is heading towards £120/MWh, even for gas and coal when the carbon taxes start to bite (it is what they are for).

    Personally I think everyone should play by the same rules. Electrical generation needs a central control system, even a distributed network. How long would the interweb last without agreed standards and controls.

    Not sure about wind turbines but there are allowances for businesses investing in capital equipment. For example as the equipment wears out and reduces in value you can offset the loss of value against company profits. I've no idea over what period a turbine can be written off.

    Edit: Looks like 8% a year..

    http://www.energyclever.com/index.php?solar=capital-allowances

    "The enhanced capital allowances do not apply to Solar PV and Wind Turbine systems as they are generating equipment,not energy saving equipment. Instead a solar PV or a Wind Turbine system may be claimed under the new annual investment allowance of £25,000 (April 2012, previously £100,000) ) and then under the special rate writing down allowance of 8 % (April 2012 )."
  3.  
    You have never been able to get subsidies as well as tariffs its part of the rules if you have any sort of government support it has to be paid back in full before your entitled to any generation incentives. Its all on the Ofgem website. In fact its worse than that. Councils now expect a S106 (bribe) agreement to be in place before any planning application is accepted and is normally based as a % of the nameplate capacity.

    Grants in Scotland: Part 2

    Spoke to my mate who works for an energy quango in a regional office in Glasgow, England.
    Apparently there are some grants up there, one for £6m has just closed.
    Most is administered though the Energy Saving Trust Scotland.

    Thanks Steamy - looks like those are all for community energy schemes but interesting.

    Posted By: SteamyTeaScotland has an aim to be powered by 100% renewable energy
    Not quite, the actual aim is a lot less ambitious/more realistic/completely inadequate: equivalent of 100% renewable electricity (not energy):

    http://www.scotland.gov.uk/Topics/archive/National-Planning-Policy/themes/renewables

    Scottish Government Policy is to generate the equivalent of 100% of Scotland's gross annual electricity consumption , the equivalent of 11% of Scotland's heat demand met from renewable sources and 500 MW of community and locally-owned renewable energy, all by 2020.
    I think that's saying they want to produce a certain amount of energy from renewables. That amount is the same as the annual electricity consumption. It's also the the same as 11% of the heat demand which is a bit surprising as I thought electricity was generally between a 10th and a 6th of total energy use and there's no mention of transport there.

    (Off to look at some of the links from that page which might have information on subsidies other than generation for the big turbines.)

    Actually, it seems the 11%-of-the-heat-demand aim is separate from the 100%-electricity aim:

    For example, the renewable heat target of 11% will be built upon a much wider development and uptake of such sources as geothermal, solar and biomass heat which will rely on access to the Renewable Heat Incentive for support; meanwhile, the transport target relies at present on the success of the Renewable Transport Fuel Obligation, but will depend much more over time on advances in the electrification of private and public vehicles.

    Ah, it was ironic - I like it!

    The Bentley (Microstation) 'Dataset' regionally customised (very poorly) from the American base-Dataset is titled Dataset_GB. Now that rules out N Ireland, IOW, Hebrides, Orkneys, Doggerland etc - but is supposed to include IOM and Channel Islands (which are neither GB nor UK), and Republic of Ireland! That's American error, but I always wondered about homegrown-error GB plates on cars. The now universal UK label seems to have originated elsewhere than from 'here' - good invention.

    GB is the ISO country code for the UK. The UK (GB) and Ukraine (UA) agreed not to argue over “UK”. That's why the UK is shown as GB or GBR at the Olympics, etc, even though there might be players from NI.

    http://www.iso.org/iso/country_codes/country_codes

    For this reason the Ukrainians are a bit teed off that the UK uses .uk for its Internet top-level domain - it's a historical accident left over from when the Internet was mostly academic and JANET (the Joint Academic Network) used .uk. AFAIK, the UK is the only country not to use its ISO country code for its TLD though, of course, only a few US sites are actually in the .us domain.

    What should we call our island then, if 'Great Britain' means something else? If Hind is the land, Hindi is the language, Hindu is the religion and Hindia is the nation, maybe, in reverse pattern, our main island should be called Brittania once more. Or Pretani as the ancient Greeks called their source of tin, or Pretanack as the Cornish still say.

    In my view anyone getting a subsidy to construct a wind turbine which subsequently is not used should pay the money back. I regularly pass a wind turbine located outside Runcorn Station in Cheshire and in the three years it's been there I've never seen it turn a blade.

    Edit . A quick search suggests the turbine was installed in 2009 by Virgin Trains, so come on Virgin why is your turbine not operational?

    The island is Great Britain. It has three countries on it (England, Scotland and Wales). They're all parts of the United Kingdom (at least for now) as is Northern Ireland (at least for now) which not in or on Great Britain (at least for a geologically long meaning of now).

    But using the letters “GB” as a code for the United Kingdom is reasonable.
