Revenue proposal objectives• Reduce the cost of transmission in Tasmania while at least 

maintaining service levels• Costs:

– based on future efficiencies, including from merger – achieve real cost reductions

• Service targets:– at least maintain level of service, extract higher performance from 

current assets– agree appropriate levels of security and reliability with customers for 

dedicated assets

Page 14: Transmission Revenue Proposal - AER

• lower transmission prices to support customer sustainability• at least maintain the present level of service but at lower cost• reflect the impact of lower demand in future plans• maximise the way we use assets rather than building more• set tougher efficiency targets• reduce our rate of return • reduce the regulated asset value

Customer feedback themes

Page 15: Transmission Revenue Proposal - AER

Supporting lower prices for consumers• Since the transitional revenue proposal and decision we have 

considered customer feedback – including adopting the AER’s view on cost of capital– further opex and capex reductions– further reduced our economic depreciation – permanently forgone $37 million under‐recovered allowable revenue

• Our revenue proposal is lower than AER March decision outcome– we have used our lower revenue figure to set prices for 2014‐15 

rather than use the transitional decision revenue
