Interesting article, if one allows for the general bias.Fascinating to me that this was the first off-shore wind project - I hadn't realised they had been operating for so long.
I was trying to put this into context for that time... Ford were replacing the Sierra with the first generation Modeo while this was being built. Given how far the current Mondeo has come when compared with the last of the Sierra's gives me some inkling how far the engineering for wind turbines has probably progressed too.

The worlds first wind farm pensioned off: a post-mortem
Capacity factor of 22% and only generated 55% of the anticipated output.
No doubt there will be some who think this performance good. They are entitled to that view but this just goes to show that the wind industy's predictions should be taken with a huge pinch of salt.
No mention of the minimum capacity factor i.e. how much back-up was required.Capacity factor of 22% and only generated 55% of the anticipated output.

I would suggest either 0% or pretty damned close to that when no wind. i.e. 100% back-up.Also, don't forget down time when there's no need for wind and constraint payments made for the white elephants to stand idle.

Proven reliability?
Other than being the SWT 6.0-154 supplied by the biggest manufacturer of Offshore wind turbines and their current model, most widely deployed last year and producing on multiple sites currently....... Germany : Anzetel
Germany : Arkonabecken Südost
Germany : Gode Wind I
Germany : Gode Wind II
Germany : Veja Mate
United-Kingdom : Dudgeon
United-Kingdom : Galloper
United-Kingdom : Hunterston Test Site
United-Kingdom : Race Bank
United-Kingdom : Westermost Rough
I'd say the odds on it being a better more reliable turbine is high

I thought that yesterday Sturgeon was flying around the first ever floating wind farm.
Surely she should have been swimming round it?She seems to be a graduate of the Richard Branson school of self promotion.
Presumably the device in which she was flying produces zero carbon during its lifetime?

Which turbine does it use ?
The Bottom Line - Batteries - @bbcradio4 http://www.bbc.co.uk/programmes/b096jb29
This episode has centrica peak supply division (currently gas but looking at battery), a next-gen battery manufacturer and a company who make battery farms talking about advances in storage that will enable local generation to take off.
They think there will be a tipping point where local storage can resolve the variability of renewables.
I hadn't even heard of lithium-sulphur batteries... But right now they have prototypes with 3x energy density of lithium-ion. Apparently it's only the start if the technology.
A company using recycled leaf batteries to set up battery farms.
A good listen.

Has the Leaf really been around so long that a substantial number of batteries are available to be repurposed?This episode has centrica peak supply division (currently gas but looking at battery), a next-gen battery manufacturer and a company who make battery farms talking about advances in storage that will enable local generation to take off.

Rolando,
Don't be so stupid. You look an idiot.
Grow up and join the conversation - rather actually questioning whether things 'float'.
I would imagine that a lot of effort will have been put into the tethering technology for both location (based on oil and gas rig work?) and electrical connections.Don't be so stupid. You look an idiot.

Presumably also it will have been a requirement to consider the marine environment and maybe even the movement of submarines.
What sort of new and previously untested technology (untested in the sense of deployment long term for real production use 24/7) might there be that could add risk to the project success?
A small scale scheme that'll work using 100 year old kit
Shame we don't all have a fast flowing stream at the bottom of the garden.
