The Eastern Gas Pipeline (EGP) is a {{convert|797|km|mi|abbr=on}} natural gas pipeline.{{cite web |url=https://www.aemc.gov.au/energy-rules/national-gas-rules/gas-scheme-register/nsw-eastern-gas-pipeline |title=NSW: Eastern Gas Pipeline |publisher=Australian Energy Market Commission |access-date=16 May 2018}} It is a key supply artery between the Gippsland Basin in Victoria and New South Wales, Australia. The EGP is currently operated by Jemena.{{cite web |url=http://jemena.com.au/about/what-we-own/our-assets/eastern-gas-pipeline |title=Eastern Gas Pipeline |publisher=SGSP (Australia) Assets Pty Ltd |access-date=16 May 2018}}

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. Gas is fed to the EGP at Longford and Orbost, and by the VicHub interconnect facility.

Capacity up to 2016 was 106 PJ per annum, and during 2016 was increased by 22 PJ per annum. Current capacity in 2018 was 350+ TJ per day.{{cite web |url=http://jemena.com.au/industry/pipelines/eastern-gas-pipeline |title=Eastern Gas Pipeline |publisher=Jemena |access-date=16 May 2018 |date=24 April 2018}}

Pipeline users

A 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.{{cite web |url=https://www.agl.com.au/about-agl/media-centre/asx-and-media-releases/2015/may/agl-secures-long-term-gas-transportation-with-eastern-gas-pipeline-agreement |title=AGL secures long-term gas transportation with Eastern Gas Pipeline agreement |publisher=AGL |access-date=16 May 2018| date=19 May 2015}}{{cite web |url=https://www.pipeliner.com.au/2015/05/19/agl-awarded-eastern-gas-pipeline-transportation-agreement/ |title=AGL awarded Eastern Gas Pipeline transportation agreement |work=The Australian Pipeliner |publisher=Great Southern Press |access-date=16 May 2018 |first= |last= |date=19 May 2015}}

History and construction

Survey work and land access negotiations were undertaken by LandPartners.{{cite web |url=http://www.landpartners.com.au/project-item/eastern-gas-pipeline/ |title=Eastern Gas Pipeline |publisher=LandPartners |access-date=16 May 2018}}

The EGP project was initiated by BHP Petroleum and West Coast Energy. 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.{{cite web |url=https://www.bluescopesteel.com.au/files/pipesteel_eastern_gas_pipeline.pdf |title=Case Study - Pipesteel - Eastern Gas Pipeline |publisher=BlueScope|access-date=16 May 2018}}

The pipeline was commissioned in 2000 and owned and operated by Duke Energy. Estimated cost was AUD450M.

API 5L X70 and X65 grade steel pipe with a fusion-bonded epoxy (FBE) coating was used.{{cite web |url=https://www.pipeliner.com.au/2016/03/16/victorias-productive-pipelines/ |title=Victoria’s productive pipelines |work=The Australian Pipeliner |publisher=Great Southern Press |access-date=16 May 2018 |first= |last= |date=16 March 2016 |archive-date=23 February 2019 |archive-url=https://web.archive.org/web/20190223184902/https://www.pipeliner.com.au/2016/03/16/victorias-productive-pipelines/ |url-status=dead }} 90 kT of pipe was used for the pipeline. 27.7 kT of this was processed by OneSteel Oil and Gas from BlueScope PS5200 pipesteel.

Ownership passed to Alinta in April 2004 when Alinta purchased Duke Energy's assets in Australia and New Zealand.{{cite web |url=https://www.theage.com.au/articles/2004/03/15/1079199164789.html |title=Alinta swoops on Duke assets |work=The Age |publisher= |access-date=16 May 2018 |first=Philip |last=Hopkins |date=16 March 2004}}

Jemena took ownership and control in 2007.

In 2008 a midline compressor was commissioned at Mila, near Bombala, New South Wales, increasing capacity by 15%.{{cite web |url=https://www.bombalatimes.com.au/story/1100410/mila-gas-compressor-station-opened/ |title=Mila Gas Compressor Station opened |work=Bombala Times|publisher=Australian Community Media|access-date=16 May 2018 |first= |last= |date=16 September 2008 }} Engineering constraints included snow zone operating conditions.{{cite web |url=http://gastoday.com.au/news/enerflex_delivers_mila_gas_early/269 |title=Enerflex delivers Mila gas early |work=GAS TODAY |publisher=Great Southern Press |access-date=16 May 2018 |first=Lyndsie |last=Mewett |date=1 November 2008}} Capacity was then 98 PJ per annum.

Local Rural Fire Service personnel are given response training by Jemena.{{cite web |url=http://www.michelagoregion.org.au/mrca/images/stories/firebrigades/colinton/newsletters/Courier_95.pdf |title=Training (2) – it’s a gas |work=Colinton Courier |publisher=Colinton Rural Fire Brigade |access-date=16 May 2018 |first= |last= |date=1 October 2009}}

The Wilton lateral was commissioned in 2016.{{cite web |url=https://utilitymagazine.com.au/jemenas-eastern-gas-pipeline-expansion-now-open/ |title=Jemena’s Eastern Gas Pipeline expansion now open |work=Utility |publisher=Monkey Media |access-date=16 May 2018 |first= |last= |date=8 March 2016}}

Planning for a compressor upgrade commenced in 2013. 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.{{cite web |url=http://minister.industry.gov.au/ministers/frydenberg/media-releases/investment-continues-australias-gas-infrastructure |title=Investment continues in Australia's gas infrastructure |publisher=Ministers and Assistant Ministers for the Department of Industry, Innovation and Science |access-date=16 May 2018 |date=29 February 2016}}
