As promised, I'm limbering up for a dissection Crapper Huhne's electricity market 'reforms' ...
In last year's cold January snap we noted the uselessness of wind power on many a cold, still day when we urgently need it for heating. Same again this winter, of course, with several recent periods when wind generation output has been less than 5% of its rated capacity for whole days at a time according to the data from this useful website. That, of course, is because still air often coincides with extreme cold.
Interesting, therefore, to note that in Oz they suffer from the other side of this exact same coin: bugger-all wind output on hot days, when they urgently need it for air conditioning !
The Australian Energy Market Operator yesterday revealed ... "During the top ten per cent of summer peak demand periods, approximately 3% of total wind generation-installed capacity contributed to demand." Energy Users Association of Australia said ... "Wind does not work on hot days and there's been incidents. That obviously means we're going to have to build more generation."
Wind-farm mania is clearly sans frontier.
