Another interesting assertion by Prof Anderson on the earlier thread was what he had to say about capacity factors for wind turbines:
...the capacity factor for turbines - which ranges from low 20 to 50 depending on size and location (well sited on land probably 25-35%, with well sited offshore and bigger (3-5MW) 35 to 50%) - I recall a few years back some 3MW turbines near the Shetlands reached 52% over the year - though the Shetland is a particularly good site.
When we discussed this the other day, we were looking at figures that were much lower than this - more like 10%. Can anyone explain the discrepancy?
