APA has interests in a number of energy infrastructure vehicles:
APA provides asset management and/or operation and maintenance services to these assets. APA also provides comprehensive corporate, financial and accounting services to the Ethane Pipeline Income Fund and Energy Infrastructure Investments .
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 EnergyAustralia (formerly 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, GDF Suez (formerly International Power) and EnergyAustralia (formerly 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,
(Click here to view the Directlink Network Management Plan)
- Gas power generation – Daandine and X41 power stations,
- Coal seam gas processing plants – Tipton West and Kogan North, and
- Gas pipelines – Telfer/Nifty Gas Pipeline, Bonaparte Gas Pipeline and Wickham Point Pipeline.
APA retains a minority interest of 19.9% in Energy Infrastructure Investments, with Marubeni Corporation holding a 49.9% stake and Osaka Gas 30.2%.
APA continues to manage, maintain and operate the assets under a long term agreement with a market-based fee structure.
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 Hallett, 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 Deutsche AWM 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 3,972 kilometres of distribution mains supplying 94,836 gas users.
A supply main to the residential development in Yarrabilba was commissioned in 2014. This will supply gas to an estimated 20,000 households over the next 30 years. Connections to date have exceeded expectations supporting a positive long-term growth outlook.
Ongoing expansion work continues on the GDI Allgas Gas Network in the Gold Coast area to extend the distribution network to service up to an additional 1,100 new homes per year.
Diamantina Power Station
Jointly developed and owned by APA Group and AGL Energy, the Diamantina Power Station (DPS) is a modern high-efficiency power station comprising 242 megawatt power generation from combined cycle gas turbines, with 60 megawatt back-up power supply available from the Leichhardt Power Station open cycle facility.
AGL Energy supplies the natural gas fuel source for DPS which is delivered to site by APA Group’s Carpentaria Gas Pipeline. DPS provides a cleaner source of power generation for Mount Isa with lower emissions and higher plant efficiencies than traditional coal-fired power plants. It produces electricity to supply mines and communities in the region, with scope for further expansion as energy demand increases.
