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 2022-23 are below.

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

  • Lower through the middle of the day (when solar energy meets a proportion of demand) and late at night (when demand is lowest), and
  • High in the late afternoon and evening (when demand is highest, and when solar energy meets little or none of this demand).

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