The proposal is for the construction and operation of two nominal 229 Megawatt (208 Megawatt net sent-out) subcritical coal-fired base-load generation plants (i.e. Bluewaters Power Station Phases III and IV) on a site adjacent to the existing Bluewaters Phase I and Phase II generating plants located approximately 4.5 kilometres north-east of Collie.
The proposal also involves the construction and operation of an approximately 63 kilometre long wastewater discharge pipeline following the same alignment as the existing Collie A Power Station wastewater pipeline with a route deviation through the coastal foredune system, and an ocean outfall consisting of an approximately 650 metre long pipe including a 110 metre long diffuser located north of the Leschenault Inlet at Buffalo Road.
