The introduction of frequency performance payments in 2025 changes how costs of regulating frequency are quantified and allocated. This article inspects historical trends in regulation FCAS enablement levels and prices.
The faster-moving nature of the FM, with the introduction of FPP, removes predictability in the indicator for frequency performance.
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...
The NEM operates at a frequency of 50 hertz (Hz) which means the alternating current should cycle 50 times a second between positive and negative voltage.
Seeking indications of possible performance at solar sites announced in the CIS tender of 2024, we inspect statistics of nearby solar farms using the GSD2024.
Using the latest GSD – GSD2024 – we take the opportunity to reflect on FCAS enablement and how enabled levels are changing between technology types.
Inspecting unit data at Willogoleche Wind Farm to ascertain drivers of the outage on 4th of February, 2025.
Units typically cut over to their BDU counterpart in 2 weeks once the BDU was registered.
We understand how the solar farm units received targets of 0 MW, when the constraint appears to simply limit the inverter count to 100.
