LESSONS LEARNT REPORT NO.3 H1 2025 BLYTH BATTERY

Summary

The Blyth Battery Energy Storage System (BBESS) in South Australia aims to transition from Grid Following Mode (GFL) to Grid Forming Mode (GFM) to provide essential grid stability services, funded by the Australian Renewable Energy Agency. This retrofit, initially anticipated to be largely software-based, has encountered unexpected challenges requiring significant hardware changes, particularly new inverter-level harmonic filters, leading to increased costs and reduced plant availability. While the GFL operations are commercial, the GFM transition is ongoing and highlighting crucial lessons for future advanced inverter projects.
