Revenue determination 2016-2020

Revenue determination 2016-2020

Our investment to deliver services to customers from July 2016 to June 2020 is outlined in our Regulatory Business Proposal 2016 (RBP 2016) and the Essential Services Commission of South Australia’s determination.

In delivering its determination, the Essential Services Commission of South Australia (ESCOSA) reviewed our proposal and sought public feedback.

A draft determination was released in February 2016 and following further feedback, ESCOSA released its final determination in June 2016. This determination set the revenue we can raise through customer bills for the regulatory period July 2016 to June 2020.

RBP 2016 balanced our customers' views and expectations with our business needs to meet various responsibilities, such as safety, drinking water quality, environmental and technical standards. It outlined our proposed investment to operate our infrastructure and deliver services our customers value.

In its determination, ESCOSA

  • supported our customer focus and efficiencies to reduce prices
  • made adjustments to our proposed expenditure
  • was roughly in line with our robust and efficient proposal.

ESCOSA’s determination resulted in a 5.2 per cent reduction in revenues compared with the revenue allowance for the first regulatory period (2013-16). This meant an $87 reduction in the combined water and sewerage bill for the average metropolitan residential customer in 2016-17.
