Below we present key information on our decisions for Water NSW’s rural bulk water services for customers in the South Coast valley. This information is not exhaustive and should be viewed in conjunction with our Final Report and Determination. 

Prices for South Coast valley will increase from 1 October 2021 

Under our decisions, Water NSW’s prices will increase as its efficient costs are higher than those used to set prices for the 2017 Determination. The key drivers of these increased costs include that the customer share of: 

  • operating expenditure for South Coast valley has increased by 31% (but by 12.2% less than proposed by Water NSW), mainly due to increased expenditure on metering and compliance, asset management planning and long term transformational strategy. 
  • capital expenditure for South Coast valley has decreased by 19.6% (but by 12.1% higher than proposed by Water NSW), mainly due to increased expenditure on internal corporate projects and dam safety compliance. 

Offsetting these factors are a lower cost of capital, which has decreased from 4.7% to 3%.

Decision on prices for the South Coast valley

Whilst we aim to set prices that fully recover the customer share of efficient costs, in setting the 2017 Determination it was recognised that full cost recovery (FCR) was likely to be unattainable in the South Coast valley over the 2017 Determination and going forward. 

For the 2021 determination period, we have decided to keep prices constant in real terms for the South Coast valley. This will recover about 32% of the customer share of efficient costs.

The table below sets out our decision on Water NSW’s prices, as well as Water NSW’s proposed prices.
