Full financial operation commences 8 June 2025.
The implementation of the Primary frequency response incentive arrangements rule is driving change in how system frequency is controlled and paid-for. The changes stem from how the NEM will incentivise primary frequency response. 6...

Friday 31st January 2025 (appeared to) experienced a very large drop in demand in NSW in a single dispatch interval - but we're now suspecting some form of data/operational glitch. However we wonder, if...
Alex Leemon of Gridcog delivered this presentation about Big Battery Revenues in the NEM at All-Energy in Melbourne last week.
To further understand the frequency drop we delve into the 4-second data (used for regulation FCAS contribution calculations) in this Part 2, looking at generating units (including BDUs).
Following a presentation with the CEC, Linton shared some insights into FCAS Regulation costs for wind and solar units over last calendar year.
Our GSD2023 was released just over 4 weeks ago. This is the second sequential article utilising the GSD2023 Data Extract to take a look across all the Semi-Scheduled units (i.e. Wind and Solar). In...
Looking back at Tuesday 13th February 2024 there's consistently large aggregate under-performance (compared to Target) across all Semi-Scheduled units in the NEM through daylight hours. The reason for the increased procurement of Regulation Raise.
