Hi Phuc,
From the design brief, we mentioned that Saibai Island residents relies on a diversified energy mix and Ergon Energy operates in the area.
One way to identify the energy consumption of the island and to draw the consumption pattern is to look at the data that’s publicly available. In Ergon Energy’s website, they have a section called ‘Energy usage data to share‘. I can see that you can filter the data by postcode or by local government area.
I hope this helps to get you started and goodluck to your research!
Regards,
Jean
