Here are Aurora Energy’s distribution loss factors, published in accordance with industry agreements including the Electricity Industry Participation Code and Use-of-System Agreements.

Distribution losses are the amount of electricity that is consumed during the delivery to customers’ premises. Loss factors are calculated to ensure that retailers and customers are only charged for electricity that they use. Distribution losses occur as electricity passes through transformers and other equipment and can also occur as a result of metering and reporting errors and theft.
