Changes to electricity prices, fees and charges 2021

June 01 2021

Each year, the WA State Government reviews electricity tariff prices, fees and charges so they better reflect the costs of making and delivering electricity through Western Australia.

This year the WA State Government has announced changes to most electricity tariffs, in line with inflation. These changes come into effect from 1 July 2021.

There are also a number of changes to the fees and charges you pay.
