Method

Ultrasonic flow meters were used to measure flow from Lake Lyell, Lake Wallace and Thomsons Creek Reservoir to the Mt Piper and Wallerawang power stations.

 

Uncertainty

The volume is based on measured data. Estimated uncertainty based on meter accuracy is +/–2%. Meters are regularly calibrated. The NSW Office of Water conducts an annual verification review on Delta Electricity’s water data.
