On 29 April 2011 the AER provided its final determination on SP AusNet’s AMI Revised Budget Application for 2009-11. The AER has since identified errors in the final determination and has issued a corrigendum which specifies the corrected figures. These corrected figures result in a -$14.46 million reduction to SP AusNet's Approved Budget for 2009-11 and not a -$4.63 million reduction as incorrectly specified in the final determination previously.
The corrigendum is to be read together with the final determination.
