This section is where you can get a better understanding of how and when you use energy. View usage data, track your current 
energy spend and get an estimate of your next bill​.

If you're trying to track if energy efficiency changes around your home or business will have an impact on the size of your bill - then this has the insights you need.



  • How can I view my energy usage
    Visit the Usage section in MyAccount to see your usage history. Usage data updates every morning so you can switch between the latest day, week, month, bill period and year. The daily view provides a rolling 30-day history that displays hourly usage over the day.  
    If you have linked accounts, each of your meters will display together on the aggregated usage graph.  
    You can download up to 365 days of your usage data using the Interval data form.  
  • How do I export my usage data?
    Visit the Usage section in MyAccount to see your usage history. The Interval data form lets you download or email up to 365 days of your hourly and/or daily usage data (in Excel format).
  • How are my estimated energy charges and estimated next bill calculated?
    The estimated energy charges amount is based on how many units of electricity you have used so far in the current billing period. The current spend is calculated based on your tariff and fixed supply charge. 
    We then use your current usage behaviour to predict what your next bill is likely to be. The estimated next bill is an estimate only and will become increasingly accurate as the end of the billing period approaches. Where applicable, this calculation includes solar buyback credits, concessions or rebates applied to your account and any outstanding debts. 
    Please note: The figure shown can vary due to factors such as actual usage and the proportion of the bill that is based on a fixed vs variable charge e.g., smaller bills will have a bigger proportional fixed charge. All amounts shown are inclusive of GST.
