SEA Gas Pipeline

SEA Gas Pipeline (“SEAGas”) is an unregulated, 680 km pipeline that commenced commercial operations in January 2004.  It transports natural gas from Port Campbell and Iona in Victoria to Adelaide and other regional markets in South Australia and Victoria as the only pipeline connecting Victoria’s gas fields to South Australia.  SEAGas also connects into the Victorian Transmission System and the TRUenergy Underground Storage facility at Port Campbell, Victoria.

At present, SEA Gas transports over half of Adelaide's natural gas requirements. Nearly all of the SEA Gas’s current load is sourced from the three foundation shippers (Origin Energy, International Power and TRUenergy) under long term agreements, with the initial term to the end of 2018, and two extensions of 5 years each.


Energy Infrastructure Investments

In December 2008 APA established the unlisted investment vehicle, Energy Infrastructure Investments Pty Limited, selling a number of its low growth annuity-style assets into the vehicle.

The assets transferred into EII comprise:


  • Electricity interconnectors – Murraylink and Directlink,

Ethane Pipeline Income Fund (ASX: EPX)

In April 2008 APA acquired a 6.1% interest in the Mariner Pipeline Income Fund (now the Ethane Pipeline Income Fund) together with the management rights for the Fund. In December 2008, an entity nominated by APA, APA Ethane Pty Limited, was appointed as Responsible Entity of the Fund. 

The Ethane Pipeline Income Fund is an ASX-listed registered managed investment scheme.  Its sole operating asset is the 1,375 km Moomba to Port Botany Ethane Pipeline (Ethane Pipeline) that for much of its length occupies the same easement with the Moomba Sydney Pipeline.  The Ethane Pipeline supplies ethane to a petrochemical facility at Port Botany under a long-term transportation agreement.  APA currently operates and maintains the Ethane Pipeline under a long-term agreement.



North Brown Hill wind farm at Hallet, South Australia is the sole asset of EII2.  It is the first investment  in  renewable  energy  generation by the EII consortium consisting of 63 wind turbines with a total wind-generated capacity of 132.3 MW. 

APA has a minority interest of 20.2%, with remaining interest comprising Marubeni Corporation (39.9%) and Osaka Gas Company Ltd (39.9%).  EII2 purchased the North Brown Hill wind farm project from AGL Energy.  It has a long term (25 year) offtake arrangement with AGL Energy for both the electricity generated and the renewable energy credits produced. 

GDI (EII) Pty Ltd

In December 2011, APA sold the Allgas Gas Network into an APA minority owned unlisted investment vehicle - GDI (EII) Pty Ltd. APA maintains a 20% interest, with equity partners Marubeni Corporation and RREEF each holding a 40% interest.

The GDI Allgas Gas Network extends from Brisbane, south of the river, to the northern tip of New South Wales, with separate networks in Toowoomba and Oakey. The network includes some small extensions in Northern NSW (Northern Rivers). In addition, a small pipeline (1km) services an ammonium nitrate plant at Moura, Central Queensland. In total, the network includes over 3,000 kilometers of distribution mains supplying over 92,000 gas users.

An expansion program of approximately $3 million per year on the GDI Allgas Gas Network is underway in the Gold Coast area, which will extend the distribution network to service up to an additional 1,100 new homes per year.

Additional expenditure in the Gold Coast area includes a $3 million augmentation of high pressure steel network supplying gas to Surfers Paradise and Broadbeach which is due to commence in 2013 with completion expected in 2014.
