Eastern Gas Pipeline
The Eastern Gas Pipeline (EGP) is a 797 km (495 mi) natural gas pipeline.[1] It is a key supply artery between the Gippsland Basin in Victoria and New South Wales, Australia. The EGP is currently operated by Jemena.[1][2] The EGP supplies more than half the gas consumed in New South Wales and supports consumers in Sydney and regional centres, including Bairnsdale, Cooma, Canberra, Nowra, Bomaderry and Wollongong.[2] Gas is fed to the EGP at Longford and Orbost, and by the VicHub interconnect facility.[1][2] Capacity up to 2016 was 106 PJ per annum,[2] and during 2016 was increased by 22 PJ per annum.[3] Current capacity in 2018 was 350+ TJ per day.[4] Pipeline usersA major user of the pipeline is AGL, who have contracted capacity from the pipeline for AGL's customers in the Australian Capital Territory and New south Wales.[5][6] Industrial EGP customers include BlueScope at Port Kembla.[7] Power generation EGP customers include Marubeni’s power station at Smithfield, EnergyAustralia’s power station at Tallawarra,[2] and Alinta Energy’s Bairnsdale power station.[7] Route and branchesThe main pipeline is 797 km (495 mi) from Longford to Horsley Park.
History and constructionSurvey work and land access negotiations were undertaken by LandPartners.[9] The EGP project was initiated by BHP Petroleum and West Coast Energy.[9] Design and construction were undertaken by Duke Energy. The initial design capacity was 65 PJ per annum, with an operating pressure of 14.9 MPa.[10] The pipeline was commissioned in 2000[2] and owned and operated by Duke Energy.[1] Estimated cost was AUD450M.[10] API 5L X70 and X65 grade steel pipe with a fusion-bonded epoxy (FBE) coating was used.[11] 90 kT of pipe was used for the pipeline.[10] 27.7 kT of this was processed by OneSteel Oil and Gas from BlueScope PS5200 pipesteel.[10] Ownership passed to Alinta[1] in April 2004 when Alinta purchased Duke Energy's assets in Australia and New Zealand.[12] Jemena took ownership and control in 2007.[1] In 2008 a midline compressor was commissioned at Mila, near Bombala, New South Wales, increasing capacity by 15%.[13] Engineering constraints included snow zone operating conditions.[14] Capacity was then 98 PJ per annum.[11] Local Rural Fire Service personnel are given response training by Jemena.[15] The Wilton lateral was commissioned in 2016.[1][3] Planning for a compressor upgrade commenced in 2013.[7] In 2016 capacity was increased by 20%, 22 PJ per year, by the addition of two new midline compressor stations, at Michelago, and at Orbost.[3][16] References
