The IESO Gets the Global Adjustment Wrong - Again

Today the final Class B Global Adjustment was posted as being $41.78/MWh.  At the end of August the second preliminary estimate of $28.94 was provided.

I wrote the issues with $28.94 in a 'better estimate' September 1st;  a month earlier I had noted my concern with July's implausible figures in the second estimates for July.

Graphing the variance between what the system operator (IESO) 'estimates' at the end of a month, and what it ends up being after the abacus work is done a couple of weeks later, there looks to be a total disintegration of ability over the past 2 months.
