The Northern and Western Isles get a different deal though. Instead of a strike price of £95/MWhr it's £115/MWhr or similar. Not sure what it currently is though.

No.

Unfortunately Philip you didn't "do" enough of the engineering. Taking the average wind speed against the turbine output at that speed is pretty much pointless. Take a look at: http://www.wind-power-program.com/wind_statistics.htm http://www.wind-power-program.com/mean_power_calculation.htm This gives a detailed overview of how to calculate the power output. It's interesting stuff.

Exactly. I was just trying to highlight that not even a normal power station produces flat out all the time.

Coal plants in the UK had a capacity factor in 2010 of 40.5%. What's piss poor?

This link shows a map of mackerel migration routes from Marine Scotland. There has always been a % of stock which passes through Faroe/Iceland waters. They claim this route has changed, which is the basis of their argument for a higher % of the TAC. Currently Iceland and Faroe get 10% of the 550000t TAC recommended by ICES. They have given themselves quotas equivalent to more than 50% if I remember right. There would need to be a massive change in migration for that to be realistic. http://trawlerphotos.co.uk/gallery/showphoto.php?photo=75944

Well done to everybody involved. A power of effort went into getting everything set up and running smoothly. Delighted with the figure they've raised!

It's a few year since I last heard about it so the designs might be a step ahead again. Lots more analysis being done these days to predict motions and consequently the effects on fuel consumption. Mostly due to technology improving to allow more work on computers without test tanks being required.

The x-bow isn't as fuel efficient in calmer conditions though. Can't see a north boat having one until somebody proves they'll use less fuel over the course of the year.

There's no saying that it isn't the same for the full lifetime of the site.

Why update it? It's aready better than any other farm. They don't have to release any of their data if they don't want to. It was just some good publicity at the time. After the 3 years that was all the data they had. 3 years is well short of what is regarded as a large enough statistical sample. The disclaimer just states that for everybody to know.
-
That figure has been online for a good few years now. Just because they haven't updated it doesn't mean that it's any different now. The point of the disclaimer is to highlight that it is a low sample period and could change.

Both could be right no?

Yup, £300million doesn't come for free, much is the pity!

If you're looking for quality wind data to do calculations on then realistically there's not much better than that of Burradale. Fit that data to a statistical curve and you're there. They have over 10 years of actual turbine data now plus whatever they had from a test mast beforehand. Following that it's a case of matching a turbine to the wind conditions. Burradale won't release anymore wind information than they have to as it's their commercial property.
