Solar panels provide numerous benefits to consumers and assist with reducing carbon emissions to help meet the NSW Government’s target of net zero emissions by 2050.
The main benefit of solar panels is the savings customers can make on their bills because they buy less electricity from their retailer when they use their solar electricity. As an added benefit, customers can be paid a solar feed-in tariff for any unused electricity they export to the grid
Every year IPART sets solar feed-in tariff benchmarks to provide a guide to NSW customers about what their solar exports are worth. This helps them understand what they might expect to be paid by their retailer for their solar electricity.
IPART’s benchmark range for 2021-22 is 4.6-5.5c/kWh
IPART’s benchmark is based on the wholesale price of electricity
When households export their solar electricity to the grid, retailers can use this electricity to supply other customers, IPART sets the solar feed-in tariff benchmark based on the forecast wholesale price of this electricity. This is the price that retailers would have paid for this electricity if they had bought it from the National Electricity Market.
Wholesale electricity is only one of the costs to retailers of supplying electricity. Retailers also have to pay network and environmental charges on all the electricity that they supply, and recover their retail costs. This is why the feed-in tariff is lower than the retail price of electricity.
The benchmark is expected to remain lower than it has been in the past
The solar feed-in tariff benchmark has fallen in recent years as wholesale prices have reduced. More generation capacity – particularly from solar panels – has resulted in these lower prices. As more customers export their excess solar electricity and increase the supply of electricity available during the day, the value of this electricity is likely to remain low in future years.
Could IPART set a higher feed-in tariff benchmark?
A higher feed-in tariff would need to be paid for by charging higher prices for electricity. This could mean that customers without solar panels would pay more overall. Many of these customers are unable to install solar because they rent or live in an apartment.
