Core Viewpoint - The Australian Energy Market Operator (AEMO) has successfully implemented the Frequency Performance Payment (FPP) reform in the National Electricity Market (NEM), which is seen as a significant milestone for the NEM, effective from June 8, 2025 [1] Reform Key Changes - The reform includes two major changes: the abolition of the "causer pays" model and the introduction of a new framework based on a five-minute contribution factor, primarily affecting semi-scheduled assets like solar and wind farms [2] - A new funding pool has been created under the FPP, charging units with poor frequency performance and compensating those with good performance, benefiting battery storage system owners due to their rapid response capabilities [2] Chain Effects and Additional Benefits - The change from the "causer pays" model will alter how large solar and wind farms share costs, eliminating existing loopholes and prompting owners to seek more accurate forecasting technologies [3] - The FPP framework is expected to attract international capital investment in NEM storage projects, enhancing grid reliability amid the shutdown of coal-fired power plants and the proliferation of investor-owned generation [3] Ensuring Mechanism's Continued Applicability - The FPP framework is designed to be configurable, allowing AEMO to respond to future market changes while maintaining the fundamental calculation rules [4] - AEMO can adjust levers to accommodate performance differences among various assets, ensuring the mechanism remains relevant as energy transition progresses [4]
