Draft decisions 2011-16 Access Arrangements for APT Allgas and Envestra (Qld) Warwick Anderson General Manager, Network Regulation 1 March 2011 Public forum Housekeeping matters Please sign the attendance sheet A record of this meeting will be made 2 Purpose of the forum Present the main features of the AERs draft decision on the access arrangement proposals submitted by APT Allgas and Envestra Inform parties intending to make submissions on the AERs draft decision 3 Submissions Submissions on the AERs draft decision

can be sent to [email protected], until 21 April The AERs access arrangement guideline provides guidance on making submissions available at www.AER.gov.au Timeframes under the NGL and NGR limit the AERs ability to accept late submissions 4 Revenues & Prices - APT Allgas The AER has determined lower revenues & prices than those proposed by APT Allgas. The main reductions are to the proposed WACC, forecast opex and tax allowance. Tariffs for haulage services are expected to rise in real terms by about 3.6 per cent per annum (on average) over the AA period. The tariffs for ancillary services were revised and will increase each year only by the rate of change in CPI. 5 Haulage Tariffs APT Allgas Real price index starts at $1 in 2005-06

Revenues & Prices - Envestra The AER has determined lower revenues & prices than those proposed by Envestra. The main reductions are to Envestras proposed WACC, forecast capex and forecast opex. Tariffs for haulage services are expected to rise in real terms by about 2.6 per cent per annum (on average) over the AA period. The tariffs for ancillary services were revised and will increase each year only by the rate of change in CPI. 8 Haulage Tariffs - Envestra Real price index starts at $1 in 2005-06 $1.70 $1.60 Envestra Qld - Actual $1.50 $1.40 $1.30 Envestra Qld - Proposed Envestra Qld - AER DD

13 Cost of capital (WACC) The nominal cost of capital has increased significantly (see following table) Debt risk premium, more than tripled since the earlier AA period. The cost of equity has decreased, due mostly to a reduction in the equity beta. The AER has set the market risk premium to its pre-GFC level of 6%. 14 WACC parameters Parameters (%) Earlier AA period APT Allgas proposal Envestra proposal AER draft

26 Return of capital Both Envestra & APT Allgas proposed shorter asset lives than used previously. The AER has accepted these asset lives increased the rate of depreciation.

increased input costs increased UAG costs, and the need for various types of non-base year costs. The AER amendments, including input cost escalators a reduction in the price assumptions for UAG various proposed step changes. The AERs draft decision results in a 12% real increase in opex compared the earlier AA period. 30 Total opex APT Allgas APT Allgas opex Actual Estimate QCA allowance AER allowance Allgas's forecast

The AER required a number of amendments, including: input cost escalation network development UAG expenditure and several of the proposed non base year costs. The AERs draft decision results in an 11% real reduction in opex compared to the earlier AA period. 32 Base year costs - Envestra $(2009-10)/km Opex/km 9000 8000 7000 6000 5000 4000

The AER accepts most of the proposed terms and conditions for both service providers. However, changes are required to provide a better balance between the service providers and customers
