The new pipeline supplied nearly all of Adelaide's gas needs at times while the damage was repaired. The pipeline was operated by a joint venture formed in May 2001 by Pelican Point Power (a subsidiary of International Power and operator of the Pelican Point Power Station) and Origin Energy (a major Australian energy producer and retailer). In September 2003, TRUenergy (then owner and operator of the Torrens Island Power Station) joined as an equal one-third partner. The initial proposal was to build a 14" diameter high-pressure gas pipeline, operating at 15 MPa. This was modified to dual 14" pipes for 338 km of the route and an 18" pipe for the remainder when TRUenergy joined SEA Gas as to accommodate the additional capacity required by the Torrens Island Power Station. Construction commenced in October 2002, 180 km south east of Adelaide near Tintinara. Operations commenced on 1 January 2004, however the project was not officially opened until 15 March 2004. Construction was carried out on an engineer-procure-construct (EPC) basis by a joint venture between Australian pipeline company AJ Lucas Group and French company Spie Capag.
