The Commission has received an application from OZ Minerals Prominent Hill Operations Pty Ltd for a variation to its electricity transmission licence, to add an additional transformer to its licenced operations.
Current status is Initiate
On 26 July 2023, the Commission received an application from OZ Minerals Prominent Hill Operations Pty Ltd (OZ Minerals). The application seeks a variation to the OZ Minerals electricity transmission licence, to authorise the operation of an additional 132/11kV transformer, bringing the total amount of transformers authorised by the OZ Minerals electricity transmission licence from three to four.
In assessing an electricity transmission licence variation application, the Commission considers the application against the relevant licensing provisions set out in the Electricity Act 1996. It will also have regard to its primary objective under the Essential Services Commission Act 2002 (ESC Act), being the protection of the long-term interests of South Australian consumers with respect to the price, quality and reliability of essential services, and other factors as they apply to the Commission's role as an economic regulator of the South Australian electricity industry.
In making its assessment, the Commission considers advice from the Office of the Technical Regulator. Matters related to health and environment protection are regulated under separate legislative frameworks.
The application is subject to a public consultation period closing on 28 August 2023. The Commission welcomes submissions on any matters relevant to the application.
