Under the NSW Biofuels Act 2007, volume fuel retailers must ensure that ethanol accounts for at least 6% of the total volume of petrol sold in any one quarter (ethanol mandate), unless they have been provided an exemption. IPART has two ongoing roles under the Biofuels Act:

  1. to determine, and periodically review, a ‘reasonable wholesale price’ for ethanol for use in the production of petrol-ethanol blends such as E10, and
  2. to monitor the retail market (including prices) for petrol-ethanol blend and make reports to the Minister for Innovation and Better Regulation (the Minister) on the effect of a determination of the reasonable price for wholesale ethanol.
