IPART’s “time-of-day” benchmarks provide guidance to households about the value of solar exports at different times of the day.  We also publish an “all-day” solar feed-in-tariff guide.

Our time-of-day benchmarks for 2023-24 are below.

IPART’s time-of-day benchmarks reflect the variation in prices throughout the day, which are typically:

  • Lower through the middle of the day (when solar energy meets a proportion of demand), and
  • Higher in the late afternoon and night-time (when solar energy meets little or none of this demand).

Retailers can offer different feed-in tariffs throughout the day in line with our benchmarks to reflect the variation in wholesale prices, however, they are not required to.  We have found that most retailers are continuing to only offer an all‑day rate for solar exports.
