Addendum to Western Water s Corporate Plan 2016 Western Water s Corporate Plan 2016 was issued to the Department of Environment, Land, Water and Planning (DELWP) in April 2016. Following finalisation of the Melbourne Water Corporation Price Determination that takes effect from 1 July 2016, Western Water has revised its proposed 2016/17 tariffs to pass on savings to customers arising from lower Melbourne Water charges. This Addendum presents the revised sections of the Western Water Corporate Plan 2016. Page numbers within the Addendum reflect their original numbering within the Corporate Plan.
Financial analysis Western Water s Corporate Plan has been prepared after reviewing major assumptions including revised growth forecasts and the associated revenue and infrastructure expenditure impacts. The Corporate Plan continues to deliver the $100 per annum Government Water Rebate to residential customers until the end of the current regulatory period and assumes that continued operating efficiency savings will contribute to lower customer tariffs in the next Price Determination period. Revenue New Customer Contributions (NCC) revenue forecasts have been reviewed in line with revised growth forecasts and analysis of current trends in developer activity. In particular, consideration has been given to gifted asset contributions due to growth in Greenfield development as compared to infill development. Operating revenue forecasts reflect revised growth forecasts and price increases established under the 2013-2018 Price Determination. For the 2018/19, 2019/20 and 2020/21 years, a price increase has been assumed that reflects continued operating efficiencies, a revised forecast of customer growth, and a return on the increasing capital expenditure. Expenses While local water sources will continue to be optimised, the assumed return to dry climate scenario requires the business to rely on transfers from the Melbourne system to meet customer demand. Charges associated with supply from the Melbourne system are under review with the financial forecasts reflecting the Melbourne Water Corporation Draft Determination released by the Essential Services Commission. Expenditure forecasts reflect a continued focus on delivering operating cost efficiencies to meet the $100 customer rebate while ensuring achievement of customer and community service levels. In line with the negotiated Enterprise Agreement, a 2.5% increase in employee expenses has been factored in assumed until December 2017, with 3.0% assumed beyond that period. Interest Borrowing costs reflect interest expense associated with existing fixed rate loans and forecast loan maturities refinanced at indicative forward fixed rates for loans with an average maturity of 6 years. Future new loan financing has also been forecast at current indicative forward fixed rates and an assumed financial accommodation levy of 1.9% (1.56% for 2015/16).

Tariffs and charges Western Water s Schedule of Tariffs is included in Appendix 1. The schedule is in accordance with the ESC Final Determination and incorporates CPI increases in addition to the Price Path Multiplier (PPM) identified per year plus/ minus a desalination factor. A further to reflect the lower electricity expenditure post the abolition of the carbon tax effective from 2014/15 is also included, as well as an to reflect changes in bulk water prices following Melbourne Water s price submission. For example: Residential water tariff (20mm) for 2016/17 would be calculated as follows: $250.99 x CPI x PPM x Desal Adj - Bulk Water Adj - Carbon Adj or $250.99 x (1 + 1.31%) x (1 + 3.3%) x (1 +1.026%) - $55 - $1 = $209.37 The rising block tariffs structure was introduced on 1 November 2004. The tariffs included in this Corporate Plan through to the end of 2017/18 are in accordance with the ESC Final Determination (cap) and with consideration of the Government Water Rebate (GWR) initiative. A smoothed price path was applied from 2013/14 consisting of water services and water usage at CPI+3.3% and CPI+1.30% for sewerage services. The known impacts of the desalination (D factor) have been incorporated into water service and usage tariffs from 2014/15 onwards. No further s will be made after 2016/17 due to removal from the desalination pool. The financial statements have been prepared showing the $100 rebate credited to residential water usage customers each year until 2017/18, with prices beyond the current regulatory period being absorbed into the tariff process. For the years 2016/17 and 2017/18, a Bulk Water Adjustment has been applied to pass onto customers reductions in Melbourne Water Charges. For the years beyond 2017/18, the tariffs assume a price path that reflects maintenance of current operating efficiencies, revised forecast customer growth and increases in the regulated asset base as a result of capital expenditure in this Water Plan period. Customer impact snapshot Western Water has undertaken detailed analysis of the impact of the price increase on customers using 150kl, 200kl and 250kl per annum. The resulting tables are included in Appendix 2. New customer contributions (NCC) NCCs are proposed at $4,226.36 per lot for Greenfield (inclusive of water, sewer and potentially recycled water) and $2,112.66 for infill lots, regardless of the number of services provided. NCCs are assumed to continue to increase by CPI each year. Restriction levels The Corporate Plan 2016 assumes that all serviced areas remain on Permanent Water Saving Rules (PWSR) for the five year period. This restriction level is expected to be in line with metropolitan Melbourne predictions. Table 11 shows anticipated reductions in demand for each stage of restriction compared to a totally unrestricted approach to water availability. Table 11: Reduction in demand (est.) for each water restriction stage Restriction stage Estimated reduction in demand PWSR 2.9% Stage 1 2.9% Stage 2 8.0% Stage 3 12.0% Stage 3a 15.0% Stage 4 17.9% 39
