The Coordinator of Energy received a submission from the Australian Energy Market Operator (AEMO) on 13 April 2022, seeking to trigger the Non-Cooptimised Essential System Service (NCESS) procurement process for a fast frequency response service.
The Coordinator has, in accordance with section 3.11A of the Wholesale Electricity Market Rules, determined that the NCESS procurement process should be triggered in this instance.
You can find the Coordinator’s full determination outlining the reasons for triggering the NCESS procurement process, along with AEMO’s submission, on our website.
