Turbulence in the Wind Industry: PPA Renegotiations, Turbine Collapse, and Lidar Advancements

In Allen's part of the USA, an escaped emu that was on the loose! We then discuss an investigation into a wind turbine collapse at the Akmene wind farm in Lithuania, which was caused by a malfunctioning sensor that provided incorrect data to the turbine controller. The root cause analysis took several months, and the wind farm was shut down until the issue was resolved. Shifting to policy news, the podcast analyzes the UK's latest CfD auction round which awarded 1.5GW of onshore wind capacity across 24 projects in Scotland and Wales. Offshore wind was absent from this round due to limited funding availability and inflation concerns. In the US, Equinor and BP are seeking to renegotiate offshore wind PPAs for their Empire Wind and Beacon Wind projects off Massachusetts unless they can achieve a 6-8% rate of return. On the technology front, we discuss a PES Wind Magazine article from Vaisala about how lidar systems can measure turbulence intensity to improve wind farm performance. Mounting lidar systems on turbine nacelles provides hub-height data to anticipate incoming wind conditions. To close, we cover news that EDF Renewables will repower Africa's oldest wind farm in Morocco, doubling its capacity to 100MW with new Siemens Gamesa turbines.

It was roaming around scaring local residents. And in fact, the, the local animal control officer said, Hey, be careful because emus are dangerous. But they did capture the emu. He would have been left behind by a former owner who moved out of state. And just left the emu behind and the new owners of the property were willing to help cooperate to kind of capture the emu. So the emu will have a new home with a local species expert and I assume that local species expert is in Australia. So you're getting another emu, Rosemary. Because Massachusetts is not the right place for those things. Rosemary Barnes: Oh, all right. That, that hurt, that hurt my ears as an Australian. Can we just clear one thing up? It's emu, emu. It's not an emu, it's an emu. You, you Americans, you know, like you don't get to take an Australian animal and give it your own, your own name.
