Gladstone Power Station Joint Venture


Rio Tinto sought minor variations under section 91A of the Competition and Consumer Act 2010 (the CCA) to authorisations A91205-A91207 which authorised a number of electricity supply agreements involving the Gladstone Power Station.  The minor variations are proposed to allow amendments to the relevant authorised agreements in response to the change to a five minute settlement period under the National Electricity Rules.

Further detail on the proposed minor variations are available under the Application heading below.

On 29 October 2021, the ACCC issued a determination granting authorisation and interim authorisation to the minor variations.
