Stanwell Corporation Limited & Diamantina Power Station Pty Ltd

Summary

Stanwell Corporation Limited and Diamantina Power Station Pty Ltd (the applicants) are seeking reauthorisation of the technical and operational arrangements related to the operation of the North West Power System (NWPS). Specifically, the parties are seeking authorisation to agree to rules related to the coordination of dispatch of generators, and demand management and load shedding of certain electricity consumers within the NWPS (the Dispatch Protocol). The NWPS is an isolated electricity generation and transmission network based in Mt Isa and is not connected to the national grid.

The Dispatch Protocol was previously conditionally authorised on 29 January 2015. The condition imposed on the authorisation requires the applicants to notify the ACCC in writing of any amendment to the Dispatch Protocol or schedules to the Dispatch Protocol within 10 days of the amendment being made, with the exception of amendments made to Schedule 5 – Forecast Data Format or Schedule 6 – Key Contact Details. The applicants are also seeking to extend the exception to this condition to apply to additional Schedules.
