Windy claims for wind farms exposed

The latest VENCorp annual planning report has yet more bad news for wind farms.

To the usual problems - that when the wind don’t blow, the power don’t flow - add the fact that the ones already installed at great expense aren’t producing as much power as promised.

From pages 30 and 33 we read that VENCorp has had to revise future summer wind generation from 24 per cent to 23 per cent of installed capacity, and winter wind generation even further down - from 27 per cent to just 19 per cent of capacity.

This is “based on the analysis of actual half-hourly wind generation during peak times”. Ugly, expensive and next to useless.

Thanks Andrew

To revise "winter wind generation even further down - from 27 per cent to just 19 per cent of capacity" means (do the math) a 30% decrease in total output (19/27ths) and 42% increase (27/19ths) in cost per unit output (both initial and continuing costs).

When will the "TRUE" ecomical cost of wind generation be disclosed? Without the goverment dole windmills would have been delgated to the scrap heap history.
