We set the minimum feed-in tariffs that your energy company pays you for power you export to the grid (via sources including solar panels).
Minimum feed-in tariff
We set the minimum feed-in tariffs that your energy company uses when they charge you for electricity use, or when they pay you for power you export to the grid (via sources including solar panels).
The 2017-18 minimum feed-in tariff for solar system owners is 11.3 cents per kilowatt hour
The 2017-18 minimum feed-in tariff for households and businesses who feed power back into the electricity grid from small renewable energy sources (like solar panels) is 11.3 cents per kilowatt hour. From 1 July 2018, retailers will be able to offer solar system owners a choice between a single rate or 'time-varying' tariff.
The 2018-19 'single rate' feed-in tariff is 9.9 cents per kilowatt hour
The single rate feed-in tariff applies regardless of the time of day or day of the week. This tariff will apply from 1 July 2018.
The 2018-19 'time varying' feed-in tariff is between 7.1 cents and 29 cents per kilowatt hour
Under the time varying tariff, customers will be credited between 7.1 cents and 29.0 cents per kilowatt hour of electricity exported, depending on the time of day. This tariff will apply from 1 July 2018.
Time varying tariffs from 1 July 2018
The time-varying tariff for certain times of day is outlined in this table:
|Period||Weekday||Weekend||Rate: cents per kilowatt hour (c/kWh)|
|Off peak||10pm to 7am||10pm to 7am||7.1 c/kWh|
|Shoulder||7am to 3pm, 9pm to 10pm||7am to 10pm||10.3 c/kWh|
|Peak||3pm to 9pm||n/a||29.0 c/kWh|
We set the minimum feed-in tariff paid to owners of small solar systems for the power they sell to the grid
Our Minimum Electricity Feed-in Tariffs to Apply From 1 July 2018: Final Decision marks the first time that retailers are able pay solar system owners either a 'single-rate' or 'time-varying' tariff.
We are introducing time-varying tariffs to address recent developments
We recently completed an inquiry into the value of distributed generation. This included the value of electricity generated from alternative sources, like solar power. The inquiry recommended that solar system owners are paid a price that better reflects the wholesale cost of electricity at the time they sell it into the grid. As a result of the findings retailers will be able to offer customers either single-rate or a time-varying feed-in tariff from July 1 2018.
Solar system owners will also have the opportunity to shop around to choose a tariff-type that best suits their individual circumstances.
We calculate the minimum feed-in tariff by forecasting the wholesale price of electricity for the year ahead
The wholesale price varies across different times of the day due to changing supply and demand. As solar panels generally export power between certain hours of the day, we only use the forecast wholesale price for electricity during these ‘solar hours’.
We also consider the costs that are avoided when your retailer buys your solar power instead of power from a large scale generator. This includes the cost of power that is normally lost when it travels long distances through the transmission network from a large central generator and the cost of the fees and charges your retailer would normally pay to the Australian Energy Market Operator when they buy wholesale energy.
The minimum feed in tariff also includes a price that is paid to account for the avoided social cost of carbon attributable to a reduction in air pollution due to the energy exported by your solar panels. This rate is currently set at 2.5 cents per kilowatt hour (c/kWh).
