Hallett 2
Hallett 2 Wind Farm, also known as Hallett Hill Wind Farm, was completed in late 2009. It consists of 34 Suzlon turbines each 2.1MW, giving an installed capacity is 71.4MW. Up to March 2011 it was averaging a capacity factor of 39%.
In December 2010, AGL identified that under certain wind conditions tones from the wind turbines were audible at the nearest residence. Resonance dampers have since been installed to address this tonality issue with the wind turbines - http://www.esm-gmbh.de/EN/Products/Tuned_mass_dampers. Noise testing has confirmed that this permanent acoustic treatment has fixed the tonality issue - http://www.agl.com.au/about/ASXandMedia/Pages/AGLfixestonalityissueatHallett2windfarm.aspx
