This Lessons Learnt Report outlines the key learnings Meridian Energy Australia has learnt from the period between October 2019 – April 2020.
The 44 degree day on January 31st, 2020 revealed a need for us to check the temperature data from inside the turbines. That day, despite high winds, yielded low-to-moderate farm output power during the peak heat of the afternoon. After some investigation, we determined the cause of this was the internal temperature sensors of the turbines reached a temperature high enough to trigger internal shut-down.
Hence our farm was experiencing high wind speeds but due to high temperature was producing nearly zero power output and so we needed to ensure our forecast incorporated this technical feature of the wind turbines installed at Mt Mercer.
