VENCorp approach to planning Based on requirements in the National Electricity Rules, VENCorp’s Transmission Licence and the Victorian Electricity System Code. Captured in three documents –Electricity Planning Criteria –Regulatory Test –Connection Augmentation Guidelines

Electricity Planning Criteria Investments decisions based on market benefits limb of the AER’s regulatory test and considers: –Probability-weighted impact on supply reliability –Value that customers place on reliability –Cost of additional capacity Decision to invest –benefits > costs – proceed with investment –benefits < costs – do not proceed with investment

Connection Augmentation Guidelines Where an augmentation is required to comply with a NER specified access standard –the connection applicant will be required to fund that augmentation Where an augmentation is required to increase the power transfer capability of the network –VENCorp will consider applying the regulatory test –If the augmentation does not satisfy the regulatory test the connection applicant can elect to fund that augmentation

Overview of Chapter 9 Chapter 6A outlines the economic regulation of transmission services. Part A of Chapter 9 sets out the jurisdictional derogations that apply to Victoria and VENCorp in particular Clauses 9.8.4B to 9.8.4F modify Chapter 6A with respect to the transmission revenue regulatory regime for the Victorian Transmission Network.

VENCorp’s revenue setting regime The transmission revenue regulatory regime that applies to VENCorp must comply with the following principles: –the amount of VENCorp’s maximum allowable aggregate revenue for a relevant regulatory period must not exceed VENCorp’s statutory electricity transmission-related costs; and –VENCorp's maximum allowable aggregate revenue must be determined on a full cost recovery but no operating surplus basis.

Terminology in the revenue proposal Committed Augmentations –identical to historic capex Planned Augmentations –identical to forecast capex Operating and Planning Expenditure –similar to opex Prescribed Services –Recovering costs of other TNSPs (SP AusNet, Murraylink)

Committed augmentations $150 million worth of committed augmentations commissioned during regulatory period Derived from –Contestable Projects (e.g Rowville and Moorabool Transformers) –Non-Contestable Projects (e.g. interface works) –Projects not rolled into SP AusNet’s asset base

Planned Augmentations Forecasting around $350 million (real) over six year period driven by –Increase in regulatory period (from 5 to 6 years) –Cost estimates based on upper end of reasonable range –Increase in load growth –Location of new generation and potential new interconnection upgrades to meet load growth
