A. 'Investment efficiencies.xlsx' contains spreadsheet models of investment efficiencies from:
(1) More efficient investment in generation and load
(2) Increased certainty/durability of TPM regime
(3) Greater scrutiny of investments

Monte Carlo analysis has been used to test assumptions and arrive at central estimates of benefits from items (1) and (2). The results of that 
analysis is summarised in A. in the 'Summary' sheet. 

The .png files show the input assumptions (parameter distributions) and output distributions from the Monte Carlo analysis.
