3,000 tonnes of armored concrete per 5 MW turbine ? That's 2,000 tonnes of armored concrete per MW effective, assuming a 30% capacity factor. That's a lot. Isn't there a little commodity cost sensitivity issue there?
Talking of wind, what's your opinion about that paper on wind farm interconnection:
http://www.stanford.edu/group/efmh/winds/aj07_jamc.pdf
It came out a year ago and I thought it was pretty interesting, in particular figure 3.
Mind you, I have a "little" disagreement with their discussion of reliability benchmarks.
you are the media you consume.
Maintenance, possibly an interesting experience too.
Dutch, I think...got the gist of it...
That graph was indeed interesting; I must admit that I found the rest of the article mostly confusing. In the long run, we're all dead. John Maynard Keynes
What really matters for high grid penetration of wind power is effective available power at a given reliability. And they actually show pretty good results from geographic balancing. 20% load factor at 79% reliability over a 850 km x 850 km area. Not great but pretty good and certainly a lot better than a single location.
Do you know of similar studies for European countries?
