Wind Turbine Generator - Loss & Uncertainty

[racv2]

Sorry for crossposting, I was just wondering if anybody could help me out with a good source of reference or literature on the subject of Production losses and uncertainty calculations for a Wind Turbine Generator (600 kW)
Also, trying to find information on how to calculate P90 values (exceedence probability).
Tried creating a spreadsheet based on some online references but haven't been able to get anywhere.
Any help would be greatly appreciated.

Come on, there is plenty of information using Google;

Um, I managed to do vaguely similar for a high school physics report back in the mid 90's when the internet was new fangled and Google just a glimmer in a programmers eye. I"m sure with a determined effort you can work it out.

Thank you metengr.

Are you implying I am lazy? JK

I am actually trying to understand the math behind the calculations. I got the theory already from some of the links you posted in fact.
Created the spreadsheet attached now trying to make sense of the numbers.

JK;

Nope, but perhaps green.

All kidding aside, I would suggest you contact GL - Garrad Hassan.

In practice, Germany and the UK are getting between 8% and 23% of the rated power nationally for their several thousands of wind turbines.

That is, you need to buy five to six wind turbines (each mounted in a "good" sighting location by national utilities) to get the rated power of one wind turbine.

I was looking into this a few years ago. The figure that seemed to be in use then was 15% which fits well with the 8% to 23%.
