Expenditure forecast assessment guidelines - March workshops

7 March 2013

Category analysis workstream - Replacement and demand driven augmentation (Transmission)

This workshop discussed definitions for replacement and augmentations expenditure, and sub-categories of expenditure, as well as appropriate measures of volume of activity undertaken for these categories. This workshop also discussed the impact of other exogenous variables on the expenditure recorded against replacements and augmentations, relative materiality of particular exogenous variables, and methods for defining and measuring material exogenous variables.

Category analysis workstream - Repex model, auges model, demand forecasting (Transmission and Distribution)

This workshop covered details of the AER’s replacement and augmentation expenditure models (repex and augex models) as discussed in general terms at its working group meetings on 7 and 8 March. This workshop also covered issues around the preparation and use of demand forecasts as a key input to the AER’s assessment of capital expenditure allowances, including as inputs to the augex model.
