Predicting the wind - update

Just an early morning comment. This is the latest NETA data

Notice NETA almost got it right. But the wind arrived late, about settlement period 7 ( 3.30am) on the 23rd when nobody wants it. NETA had estimated that the wind would arrive during peak household demand period in the evening of the 22nd.

Luckily, the amount of power (even from new higher wind) is so inconsequential it would not have caused any issues. But if we had been relying on wind for 30% of our power there would have been mayhem.

Look at the graph.  When I say the "wind arrived" I actually mean the total metered wind turbine output rose from 2% of the much lauded turbine rating to a peak of 18.5%.

Just as an example. If this was the planned Alaska windfarm at East Stoke in the Purbecks which has a projected boiler plate rating of 9.2MW, the actual output would have risen from 0.184MW through to a peak of 1.7MW. That of course ignores the amount of power used internally to heat the turbine blades and gear box to stop them freezing.

Don't forget, these are nationally based statistics, and it has been like this (or worse) for days
