The Waddi project, 150 kilometres north of Perth, will comprise 57 turbines for an installed capacity of around 170MW, and up to 80MW of static or tracking flat-plate PV panels.
No announcement has yet been made on turbine choice, but a recent amendment to the planning permit has allowed tip height to be extended from 152 to 165 metres, together with changes to the location of the transmission line.
The wind project was initiated in 2008 by Wind Prospect, which sold the development to Trustpower last year.
Wind Prospect has remained involved in helping push on the wind element and achieving planning approval for the solar installation.
