The Goldfields Gas Pipeline Joint Venture participants propose to construct a buried pipeline from near Onslow to Kalgoorlie, via Newman in the eastern Pilbara. The pipeline would transmit gas from the existing Dampier to Perth gas pipeline to the Pilbara and Goldfields regions, initially for power generation at mine sites owned by the participants. Six lateral buried pipelines would be constructed from the main pipeline to deliver gas to the proposed gas-fired power stations at the mine sites. The pipeline would have the capacity for other developments by energy consumers along the route in the future.
