Energy distributors must provide us with voltage performance data every quarter. We use this data to monitor distributor compliance with our voltage performance standards and ensure consumer needs are met.
Voltage performance data
Maintaining steady and compliant voltage levels is important for energy consumers. It can affect household appliances and solar panel output from homes.
Energy distributors must provide us with voltage performance data every quarter. This requirement is contained in our Compliance and Performance Reporting Guideline.
We use this data to monitor distributor compliance with our voltage performance standards and ensure consumer needs are met.
In Victoria, electricity distributors must make sure that voltage levels comply with the Electricity Distribution Code of Practice (which refers to the Australian Standard AS 61000.3.100-2011).
Functional compliance is achieved if up to one per cent of measurements below 216 V and up to one per cent of measurements above 253 V are maintained across at least 95 per cent of a distributor's customers. The horizontal red line below shows where five per cent of customers experience over-voltage (graph 1) and under-voltage (graph 2) for more than one per cent of the time.
