Data format

The data is contained in csv format, covers the period 1 July to 30 June for each zone substation and contains the following information:

  • The name of the zone substation.
  • The date of the reading.
  • The time of the reading in Australian Eastern Standard Time (AEST) or Australian Eastern Daylight-saving Time (AEDT) as applicable.
  • The raw zone substation load data (in MVA) in half hour intervals (where available).

Evoenergy notes its SCADA readings are measured on the secondary side of its zone substation transformers. As per clause 5.13A(c) of the National Electricity Rules, no correction has been applied to the data provided. To avoid possible confusion, any additional data points recorded at the time of transition

between AEST and AEDT and vice versa have been excluded from the data provided. All times represent wall clock time.

Future updates

Annual zone substation reports will be provided by 31 December each year covering zone substation information for the preceding financial year.

Further information

Further information regarding the configuration of the distribution network, including system maps and tables detailing which transmission connection point substations normally supply our zone substations, can be found in our Annual Planning Report (APR).
