Interesting - was installed in 1991 with 0.45MW turbines, absolutely tiny in comparison to today's Leviathans.

Good article Dan,
                 This provides the very necessary information for future projects, Even the concrete used is being studies for it,s resistance to the marine elements.
 The companies involved and the government officials must be commended for their long term approach. This coming on the heels of the latest Wind power subsidies dropping below nuclear to an astounding 58.00 per MW  is good news for those who put their faith in Renewable Energy.
The latest news from Florida,s Nuclear power stations is that that one was certified as unfit for purpose before Irma paid a visit. It got flooded and had to be shut down, A valve in the cooling system then ceased to function and only good luck saved the plant from going the way Fukushima went.
 I believe that it is gradually dawning on even the most anti-wind turbine fractions that wind generated power and solar pv are going to have to be a large part of our future if we want to save our planet.

243GWh produced.  That equates to about 10 million quid at 4p/kWh.  About 40 million, at current domestic rates, with no fuel costs.

No doubt the cost at the time was a bit expensive.  Probably some deal of subsidy at the time.  But they had to start somewhere.

450kW was certainly not a small turbine at the time! Jounalists trying to be something they are not, as usual?

What it does do is debunk the myth, spread about by the anti renewable mob, that wind turbines never recoup their carbon footprint cost.  Note that the output was only about 25% of nameplate, so rather less than our latest off-shore additions.  Development has certainly moved on - thanks to that initial installation made over 25 years ago.  Think for a moment they could easily double that wind farm output with just one turbine, now.

And here's its lifetime production, expressed as rolling annual capacity factor.

Note that I only had annual data up to 2002, which is why it's so lumpy in the first half of the graph - there's only one data point per year. From then on, I have monthly data, so the rolling annual number was updated 12 times per year.
