The 30MW Hywind Scotland, the world’s first commercial-scale floating wind farm, performed better than expected in its first three full months in production, Statoil, the operator of the wind farm said.

Despite one hurricane, one winter storm and wave heights of up to 8,2 meters, Hywind Scotland, the world’s first floating wind farm, performed better than expected in its first 3 full months in production.
The 30MW wind farm, operated by Statoil in partnership with Masdar, is located 25 kilometers offshore Peterhead in Aberdeenshire, Scotland, and is powering approximately 20,000 UK households.
During the winter, when the wind is at its strongest, the typical capacity factor for an bottom fixed offshore wind farm is 45-60%. By comparison, Hywind Scotland achieved an average of approximately 65% during November, December and January, i.e that the wind farm was producing 65% of max theoretical capacity.
A capacity factor of 100 % means all wind turbines have generated at maximum output every second of the day.
“We have tested the Hywind technology in harsh weather conditions for many years and we know it works. But putting the world’s first floating wind farm into production comes with some excitement. Therefore, it is very encouraging to see how well the turbines have performed so far. Hywind Scotland’s high availability has ensured that the volume of electricity generated is substantially higher than expected. In addition, it has delivered without any HSE incidents,” says Beate Myking, senior vice president of offshore wind operations in Statoil.
Hywind Scotland’s first encounter with harsh weather conditions was the hurricane Ophelia in October when wind speed of 125 kilometers per hour (80mph) were recorded. These wind speeds were surpassed during Storm Caroline in early December when gusts in excess of 160 km/h (100 mph) and waves in excess of 8,2 meters were recorded.
Looking for new opportunities
“Knowing that up to 80% of the offshore wind resources globally are in deep waters (+60 meters) where traditional bottom fixed installations are not suitable, we see great potential for floating offshore wind, in Asia, on the west coast of North America and in Europe. We are actively looking for new opportunities for the Hywind technology,” says Irene Rummelhoff, executive vice president for New Energy Solutions in Statoil.
Statoil and Masdar are having an ambition to reduce the costs of energy from the Hywind floating wind farm to 40-60 €/MWh by 2030, making it cost competitive with other renewable energy sources.
“This is an ambitious, but realistic target. Optimised design, larger and more efficient turbines, technology development and larger wind parks will drive down costs, improve infrastructure and logistics,” Rummelhoff says.

Wind power engineering seems to be getting better. The key metric of success will be how well it holds up over the long-term to payback the costs of engineering, installation, and operation.
Windmills are part of a basket of energy conversion/production technologies with niche applications. That said, it should still be characterized as an artificial green blight (i.e. low-density environmental disrupter), and considered appropriately as suitable to purpose in context.
“…it should still be characterized as an artificial green blight (i.e. low-density environmental disrupter), and considered appropriately as suitable to purpose in context.”
More polite than I would offer. Call me in 2030. This unit achieves 65% performance at less than 2% of design life. It’s not even broken in.
Storage? I still favor the eagles.
Not sure about actual costs to construct but projected costs were 210m GBP. With powering 20,000 households that is just around 10,500 GBP per house
While there is a question of ROI, unreliable technology coupled with renewable drivers may not be well suited for mission critical systems, they can serve a useful purpose in other areas, including, for example: desalination, waste processing, etc.
yes Bryan, that is the kind of hard nosed calculation this kind of “reporting” always manages to avoid.
30MW *65% = 20 MW , that makes 1kW each 24/7 for the alleged 20k homes being “supplied”.
Now taking the first figure I can find, UK households use about 4000kWh per year ( slightly higher in Scotland); ie a mean of 11kW per day. So they probably could claim more than 20k for that period.
Of course they never actually give the figures they have in real,engineering numbers but have to try to obfuscate by dumbing it down into “Olympic sized swimming pool” type units.
oops 11kWh per day, that’s slightly more than 500 W 24/7 . I’m guessing the 20k households was their initial PR talk for the expected annual production.
So capacity factor during a hurricane or no wind is 0%. What do they use as backup to ensure a steady supply?
“What do they use as backup to ensure a steady supply?”
Oil. Net result… less oil needs to be used.
Except the oil plant has to be kept running all the time ready to take over when the wind speeds either drops or increases by too much.
End result, no decrease in oil usage.
The other problem is that the oil plant costs the same whether you are using it 100% of the time or 50% of the time. So not only do you to pay for the renewables, the amount you are paying for the oil power doesn’t go down.
Gas, there is virtually no oil burning generation capacity in the UK.
When they are calculating the costs of electricity generation from other forms of energy I am guessing they are taking the cost as the cost the present electricity producer is experiencing for that region. They are forgetting that the costs have tripled in the last 15 years wherever green energy has been implemented. Those tripled prices are the direct result of subsidies and infrastructure, and spinning costs … etc. to the green energy alternatives. So the real comparison to competitiveness is what will be the cost of the floating wind turbines by 2030 as compared to a past value cost ( costed out to its future value cost as of 2030) of the energy costs of the electricity provider in the year before subsidies started. If that was done the target date will have to be pushed further into the future than 2030. Already 2030 is 12 years ahead and if the real even cost date is something like 20 years ahead then you have to add additional costs of the replacement of the wind turbines because they obviously have a finite life. If this 2nd extra cost is added in then I suspect that the wind turbines will never pay for themselves as an even replacement cost alternative for coal plants.
A measure of healthy skepticism is essential for the orderly advance of science and skepticism is even more important for the orderly development of engineering and technological innovations. The “renewable” energy discourse has evolved (devolved?) to the level that it pits reason against faith, or faith against reason if you prefer.
I think the apparent “faith-based” belief that we will ever be able to develop our science and technologies to the point that we will be able to use wind and solar PV to produce and provide an amount of usable electricity that is equal to the amount that we are currently deriving from fossil fuels is more off the wall than many cult religions. We should be operating based on the principle that sometime in the future when the inevitable depletion of available fossil fuels has occurred, the amount of energy that we have in our lives will be less that we have now and that amount will come with a unit cost that is greater than today — It’s simply a fact, Jack.
that amount will come with a unit cost that is greater than today
====≠=======
what will be sacrificed to pay for this?
technology has a history of reducing costs. otherwise competition eliminates the technology or the government or the people.
when laws make the technology too big to fail they set in motion a conflict between government and the people.
in many ways the rise in populism aka brexit and trump are a direct result of this conflict.
I have no problem with renewable power systems – they are to be encouraged, but not at any cost! At present, Renewable Power Suppliers conveniently ignore the overall costs to the customer, as incurred by themselves, and also incurred by others – as needed to provide comparable base load power systems; and yet they still need subsidies.
Taking Wind Turbines as an example, the power costs passed onto the customer have to still include the subsidy costs to make their operations commercially viable, together with the further subsidised costs of providing necessary inefficiently operated standby Gas Turbine plants which are needed because of the imposed ever varying 0-100% WT capacity power demand shortfalls imposed on them to maintain power supplies during typical and frequent no/low wind conditions – even over extended winter periods of maximum power demand.
Effectively the customer is ultimately paying for massive excessive installed Power Generation capacity and extended/enhanced Power Transmission works and power losses, as well as two lots of subsidies simply to accommodate these in-built WT operation inefficiencies, – something that no amount of WT R&D expenditure will ever significantly reduce. !
A very simple total life cycle cost comparison of the like for like base load systems, i.e. systems that produce power when needed and not when available, with a Wind Farm System, standby GT’s and extended PT works compared to a stand alone base load Gas Turbine systems quickly identifies that WT’s can effectively never be economical.
We as customers are continually being conned by the WT industry! We need UK fracked gas and new GT power to rapidly fill a widening UK Energy Gap and to drive down power costs and hence all our other costs – which will assist in maintaining and re-establishing strategic industries and export trades. At least we would then be able to buy time for the necessary R&D work on base load renewable systems – needed when gas supplies run out!
” making it cost competitive with other renewable energy sources.”
So, they are admitting that it is expensive, as they do not compare it to other energy sources.
See above. Let us wait, also, to see the eventual life of these WT’s, their actual future power outputs, and also their Operational and Maintenance/Replacement costs!
” The key metric of success will be how well it holds up over the long-term to payback the costs of engineering, installation, and operation.” Given the low energy density of wind even at rated capacity the engineering cost is high. Put the device offshore and both the installation and mainetnance costs go up. Get back yto me when the project is paying its way.
“Windmills are part of a basket of energy conversion/production technologies ”
shouldn’t that have read
“Windmills are part of a basket case of energy conversion/production technologies ” ?

Sounds encouraging. IAre there and subsidies from any government being employed?
Yes, both directly and indirectly.
That’s why they’re running Drax on wood pellets from forests felled in America even though, overall, it produces more plant food (CO2) than it would if it ran on coal. Anything to keep the cost of running Drax as high as possible so it doesn’t make those seagull slaughtering whirligigs look quite so uneconomic.
Kind of like the oil industry that gets subsidized by the military.
Does not include the cost of the backup, either the fossil it keeps on the grid to do this, or the hugely expensive battery or pumped storage necessary w.o fossil for times when wind output is close to zero during winter high pressure systems.
What was the actual cost of the electricity produced? Including the connections to shore. How does that compare to other new-build installations, including fuel costs?
And the expected lifetime of the cabling to shore which must be flexed at the same points to some extent with every wave…
Those in the know say the all-in price (including construction, engineering, transmission, fuel, and O&M) for each unit of electricity, the offshore wind costs are twice the costs of a power from new combined cycle natural gas turbine.
“making it cost competitive with other renewable energy sources.”
….oh good grief….this is their bragging rights?….how about making it cost competitive with conventional energy sources….then they would have something to brag about
So in other words, the floating bird shredders suck about as much as any other greentarded energy “solution”. Why don’t we just burn cash, along with our food?
That’s the point. If fossile energy is phased out, the costs of renewable energy may skyrocket, so it is easy to be competitive. Let’s see how they perform after 5 years. ‘Before the court and on the high sea one is in God’s hands’. I hope he’ll stop that sort of renewable hubris.
Dad to go reread the context of the quote you referenced:
[ Statoil and Masdar are having an ambition to reduce the costs of energy from the Hywind floating wind farm to 40-60 €/MWh by 2030, making it cost competitive with other renewable energy sources. ]
“having an amibition” … “by 2030” … leads me to believe that this power is not even comparable to other renewable energy sources today.
I used to “have an ambition” to meet Marilyn Monroe; then Gina Lollobrigida; then… None of those “ambitions” were ever realized!
“to meet Marilyn Monroe; then Gina Lollobrigida; then… None of those “ambitions” were ever realized!”
Along with Jan Stephenson. I had to laugh, mine were never realized either.
Scottish subsidies to offshore wind is around $300 million a year….
“Part of the attraction for Scottish politicians is that the subsidies that pay for Scottish wind farms come from consumers all over Great Britain. Scottish consumption is about 10 per cent of the British total – so when the Scottish government grants planning permission to the wind industry, it is simply writing a cheque drawn overwhelmingly on English and Welsh accounts. Taxation without representation, in fact.”
https://www.wind-watch.org/news/2017/08/10/the-scottish-wind-power-racket/
“Subsidies to onshore wind in the UK now cost a little under £600 million a year, with Scottish wind taking about half”……..
that’s a pretty wild and windy part of the UK. If it can operate there it can operate anywhere. The key question is its durability and costs, as UK guaranteed energy prices to the supplier for renewables is very high which impacts on the cost to the consumer..
Hopefully it can demonstrate that low prices and renewable can be mentioned in the same sentence.
We shall see.

I loved this part:
Several things:
1) Nothing about current costs, just future hopes.
2) They’re not saying it’s as cheap as fossil power, just as cheap as renewable power.
3)
“40-60 €/MWh” is 60 cents to 90 cents US per kilowatt hour … most of the US pays around 10 cents per Kw-hr, here in the People’s Republic of California the green lunacy has me up to 15 cents per Kw-hr.[That was wrong, I’m ashamed to say, moving too fast. Thanks to those pointing it out. It should have said about 6 to 9 cents per Kw-hr … which I’ll believe only when I see it. No unsubsidized wind power I know of is that cheap.]If that’s all they are getting from fighting the weather and the waves and the hurricanes, they can all just go home now. That’s a green joke.

Willis, at 1.23 $ per euro currently, this would work out to about $50 to $73 per MWh, which is $0.05 to $0.073 per kwh. Still, it’s their “ambition”, for which no market exists.
I thought it was 6 to 9c per kwh, not 60 to 90?
YIKES! My bad … although I know of NO windfarm selling power that cheaply.

Fortunately we of the Peoples Republic of California aren’t yet the Peoples Democratic Republic of California though Governor Jerry (Green) Brown has us going in that direction.
There is always Mississippi or Alabama if you prefer a more fascist form of government.
davidgmillsatty February 17, 2018 at 8:22 pm
So if someone doesn’t like the insanely liberal politics of California, they’re a fascist. Got it.
You do understand that that kind of logic is why we have Donald Trump, I hope, but carry on …

What would be the cost without subsidies?
Ted Midd February 16, 2018 at 1:16 pm
What would be the cost without subsidies?
Somewhere between unaffordable and ridiculously expensive.
My first reaction was: If you have to ask the price …
My favorite definition of boat is: ‘A hole in the water into which you pour money.” A yacht differs only in magnitude. Renewable energy is a lot like yachts in that regard … ie. a very expensive luxury.
I’ve known a number of people who’ve been quite happy with their little bass boats to the point when the boat reached the point where you could no longer step in it without stepping through it, they went out and bought another.
I am having an ambition to win the lottery jackpot. Can someone fund me until that happens?
The key word is
I would guess that this “ambition” does not include capital costs.
yes every millionaire and billionaire that buys a yacht finds out that it is just a super expensive way of getting from one port to another port by travelling slower than you could of got there by any other means of fueled transport.

I calculates $0.25/kWh.
The key metric of success will be, how long it can keep riding the fat subsides gravy train.
That a power producing system has to be shut down when there is to much of its fuel source , has to be truly ironic given it was the free nature of this source which its selling point and the intermittent nature of its ability biggest weakness .
Utility scale solar PV from the sector leaders is headed for 20 cents a watt next year and without ocean engineering to accomplish it. Be careful buddy.
I have invented a renewable underwater breathing apparatus that is half the cost of a conventional underwater breathing apparatus. It should work fine if you don’t mind that it only works intermittently.
That’s why the grid has peaker plants and there too the costs are falling for those.
In a normal grid, you have a pretty good idea, days in advance, when the peaker plants will be needed.
With renewables, you usually have little to no notice before hand.
In a normal grid, peaker plants are only needed to provide an extra percent or two to get the grid past peak load of the day.
In a grid dominated by renewable energy, you need enough peaking power to completely take over power generation when the wind stops blowing at night.
Another point is that peaking power is usually needed for 30 minutes to an hour or so. Peaking power in a renewables dominated grid will be needed all night when the solar plants stop producing altogether.
ResourceGuy,
In the good old days, you needed some 10% backup of maximum (in our country winter) consumption for in case a huge unit failed at once and some 10% power from the neighbors for in case that at the same moment one of the other huge units was in maintenance. If you install 30% renewables like wind and solar, you need additional 30% backup for in case that there is no wind or sun, as is always the case at night and 10% of summer yield in winter for solar and 70% of the time for wind on land.
Thus in case of installing costs, all extra installations needed for wind and solar backup must be included and running them idle or full speed needs to be added to to the running costs of these renewables…
Happy, happy, joy, joy! Each floating whirligig powers up to 2.5 Algore-homes, or a Big-Wig climate meeting for 97% of a second.
And when you get near them you can hear the pounding (Swoop, Swoop, Swoop, Swop, Swoop, Swoop) of their AlGore Rhythm
“The key metric of success will be how well it holds up over the long-term to payback the costs of engineering, installation, and operation.”
Yes, that is the bottom line. Was this installation subsidized? If so, we need to add the subsidies to the metric.
Sounds like nuclear plant promoters.
Except nuclear isn’t subsidized.
And except that we never did molten salt thorium reactors because the military could not make bombs out of them.
I’d like to know the impact on wildlife, especially birds. Do many habitually fly in that location? How many are lost to the flying blades? The article did not mention that aspect.
Going out on a limb here. They’ll send an intern to count dead birds at the bottom of the windmills who will joyfully return with a count of zero deaths and as a plus the windmills will have fatter, healthier fish swimming in the shadows. At that point they’ll declare victory over solving the bird chopper problem and how they’ve also solved the world fisheries declining population problem! Full steam ahead on building more windmills at sea!
Need I say /sarc?
I’ll go farther than that. The harmonics disrupt the aquatics in the area and they all die. Forcing any future installations to be on land. 🙁
I suspect the answer is;Far fewer than before.
Just spitballing but, Statoil couldn’t possibly be just a bit biased about the performance of Hywind, could they?
This is a function of wind resource, not technological adroitness…
Unless the wind turbines are suffering mechanical issues, the capacity factor is dictated by the wind.
The capacity factor can be increased by reducing the peak capacity.
Well, those are very good numbers for winter. How about the rest of the year?
A hurricane? Your BS meter should have blown up already. Supposedly a hurricane made it further n/w than ever before, but it never got anywhere near Scotland.
By a fluke of the weather, what is always the most productive time of year was at the upper end of the expected range. Over the next few years it will average out at 35% or whatever, like all the other industrial complexes busy destroying migrating birds and bats and massively inflating my electricity bill.
Just more wind industry propaganda.
Good, I’m glad someone else spotted the incorrect labelling of EX-Hurricane Ophelia. Also, as for high productivity, it is all down to the weather. There has been very little high pressure in that area this winter, so plenty of wind.
Rich.
Ophelia was just normal weather for Scotland.
30 MW * 24 hr/d * 0.65 = 468 MWh/d… About 1,600 mmbtu/d.
A single typical Marcellus well produces 5,000 mmbtu/d of natural gas. At 7,870 btu/kWh, that’s 635 MWh/d.
Thanks
David: what are the footprint and development cost for a single Marcellus well?
The footprint is tiny. I’d have to look up the exact numbers.
Breakeven for the Marcellus ranges from $2.00-$3.00/mmbtu. At 5,000 mmbtu/d and 7,870 btu/kWh, that’s about $24/MWh.
The breakeven for offshore wind is around $155/MWh.
David Middleton,
Somewhat OT, but I’ve passed a couple NY Marcellus questions past you before. I don’t know if this is up your alley, but I hope you would entertain this one.
Without going into boring (no pun intended :)) detail, the NYDEC issued the final Supplemental Generic Environmental Impact Statement (SGEIS) which essentially bans “high-volume hydraulic fracturing.” I looked at a website recently (can’t find it again) that, I think, defines HVHF as over 300,000 gallons of water. Don’t think that this is your area of expertise, but just wondering because I have no idea. Can you do hydraulic fracturing in the Marcellus in New York (profitably) with less than 300,00 gallons of water, or did they pick this because they knew it couldn’t be done, so effectively banned on all gas exploration in NY.
Maybe bass ackwards, but what prompted my question was AW,CDL7’s question about footprint. When I was younger, I spent a lot of time in north central PA (where they allow production) and south central NY (where they ban production), and you can look on Google Earth to see the footprint of a Marcellus well (HINT: not much). Newly developed shopping centers in the area take up more footprint than a gas well (and have large parking lot for cars, heat islands, etc.). Gas wells are usually up in the hills away from the developed areas.
So after 3 months in peak/ideal conditions they performed “better than expected” providing 65% of capacity. Come back in a year and tell us how much they produced and how much was actually used and what the maintenance costs were. California plays the “energy produced” misinformation game with all its’ wind and solar installations to deflate cost/kwh. With all the talk about how wind and solar are becoming competitive with fossil fuel energy how come everyone’s utility bills are rising so drastically?
Sum up all the steel and other materials used pr. mill it is crazy. Much more than for onshore wind. Each mill has a tower of 670 tonnes, substructure of 2300 tonnes, 10000 tonnes ballast and 3 chains totaling 1200 tonnes of steel. Perhaps 10x more than an onshore mill. The cost, the energy input and CO2 emissions from the manufacturing made with fossile energy. They call this green energy. I call it subsidised industrialization of nature.
Simply getting the machine to site and installed is a huge undertaking. I am impressed they can do it. It would be better if there was only private investment involved. If it is viable it doesn’t need subsidies.
Given the storminess and waviness of the area, perhaps it would have been best to build wave generators and tidal entrainment. Are readers aware that these wind turbines consume power when the wind is not blowing? It is not just backup that is needed, it is the energy to keep them heated and turning plus 100% backup.
Didnt I tell you?
“We are actively looking for new opportunities for the Hywind technology”. Translation “We are actively looking for big subsidies for the Hywind technology”. There, fixed it.
Better than imagined, maybe?

Well, I could expect quite a lot, but right now I’m stuck with fantasies. Fantasies such as wind-generated electricity that could actually compete on cost and reliability with gas and coal generation without government subsidies and legally required feed-in tariffs. What other industries in the world actually get to have laws made that mandate that the customer buys a company’s product when there are cheaper ones available?
Don’t forget the right to feed in, plus the tariff. It is the ‘must take it’ that is causing so many losses. The wind farm is guaranteed the income whether the power is needed or not. The same does not apply to other producers. They can only sell when there is a customer. The wind farm contracts make the distributor the customer.
For this reason the South African giant ESKOM is refusing to take ‘renewable power’ even at a low price unless they can pass along the true cost of keeping their investment idling – for which they have to pay, used or not – on to the consumer. The government says “No.” They say, “Then, No deal.”
Stalemate at the moment.
So they have ambitions to reduce their costs at the low end, by 2030, to what nuclear plants in Ontario get paid now. OK then.
Yes, all is well

Paying people to vote Labour and it’ll all be legal of course. What could possibly be wrong with that?
Windmills are just stupid. And their output depends upon the wind, not whether they are floating.
I saw the stats that , just to produce enough energy to equal the typical yearly increase in consumption, one would have to build 350,000 ginat windmills, and require all of the land area of the British Isles, Ireland incuded.
