3 3 FOCUSED Wind farms Geothermal Plants Australia s power sector is redefining the way it operates following shifts in consumption trends, an increase in the use of renewable energy and stringent emissions legislation. Today, utilities, mining and industrial power producers are faced with the unprecedented challenge of optimising operational capacity to meet growing demand without significantly increasing their carbon footprint or costs. Thiess has been synonymous with Australia s landmark construction projects since becoming the largest contractor on the nation-building Snowy Mountains Hydro-Electric Scheme in the 1950s. We have gone on to construct some of Australia s most vital power infrastructure from the 1,500 MW Tumut 3 power station that forms part of the Snowy Mountain Hydro-Electric Scheme to the early site and civil works for Queensland s Tarong Power Station and the Bayswater Power Station in New South Wales. We continue to participate in the sector, executing full turnkey projects such as the Worsley Multi Fuel Cogeneration project in Western Australia. More recently, as utility, mining and industrial operators look to use cleaner fossil fuels and more renewable energy sources in their power generation mix, we have expanded our capability to include gas-fired open and combined cycle power stations, as well as geothermal, wind and solar power plants. Thiess is helping to meet the changing needs of Australia s power industry and importantly: Manages risk to deliver safe and quality outcomes that go beyond compliance and guarantee performance Retains a highly-skilled, power generation project management and construction team, which draws on the multi-disciplinary specialist skills and capability of our broader construction and services teams Invests in partnerships with internationally-recognised Original Equipment Manufacturers (OEMs) and design and technology specialists to provide a seamless and integrated capability spanning design, construction and commissioning through to handover and ongoing operations and maintenance.

4 4 ESTABLISHED AND EXPERIENCED Behind every successful power project is an experienced contractor who can work in partnership to deliver firstclass solutions in engineering, procurement and construction (EPC) turnkey contract arrangements. As a Leighton Holdings Limited subsidiary, Thiess offers clients the financial security and stability of working with Australia s largest project development and contracting company. We are one of Australia s largest tier one contractors, providing a one-stop construction solution including initial site clearing, civil, structural, mechanical, piping, and electrical, instrumentation and controls. Generally operating as the principal contractor, Thiess directly manages all construction activities, safety and statutory requirements. This approach reduces the project s direct site costs and aligns with our preference for selfperforming works where possible. Ultimately, it delivers greater flexibility and control of resources to provide certainty of delivery. Our commitment to working closely with OEM providers and their design and commissioning engineers at every stage of the life cycle from taking delivery of the equipment through to installation, pre-testing and final commissioning ensures we achieve the optimum start-up sequence. Underpinning this commitment is an understanding and appreciation of the level of documentation and verification required to satisfy handover.

9 9 CONSTRUCTION INDUSTRY LEADERSHIP Thiess has proven its ability to manage complex construction projects throughout the power generation supply chain and across the energy value chain, including coal, gas, biomass and geothermal. We are well positioned to take on the challenges and opportunities facing Australia s power sector, backed by our high-performing team that is responsible for some of the country s most significant projects, including: Chevron-operated Gorgon Project a 4,000 worker construction village and site preparation and temporary facilities for the LNG plant and marine offloading facility Chevron-operated Wheatstone Project condensate and LNG tanks, breakwater and marine offloading facility, micro-tunnel and site preparation $3.5 billion Victorian Desalination Project Australia s largest desalination plant which draws on our civil; structural, mechanical, piping, electrical and instrumentation (SMPEI); tunnelling and services capabilities $4.8 billion Airport Link, Australia s largest road infrastructure project which included the largest jacked box operation in the country.

10 10 project snapshot Worsley Multi-Fuel Cogeneration Plant Western Australia A multi-fuel cogeneration plant incorporating leading edge technology is providing Western Australia s Worsley Alumina Refinery s recently-expanded facilities with the additional steam and electricity required to boost annual production from 3.1 to 4.7 million tonnes. Thiess, in alliance with CH2M Hill, joined the Worsley Multi-Fuel Cogeneration Project (MFCG) in 2010, following the completion of the civil work foundations, to provide structural, mechanical and piping resources, and assume overall construction management responsibilities. In an Australian first, the team constructed and commissioned two AE&E duel fuel circulating fluidised bed (CFB) boilers capable of producing 550 tonnes of steam per hour, and associated coal and biomass feeding systems. Each boiler was coupled with a 57MW back pressure steam turbine and balance of plant. In another first for fuel-fired boiler plants used in industrial applications in this country, a re-heat steam cycle was installed to supply the main steam at 160 bar and 540 C to the boiler and steam turbines, further boosting power generation efficiency. Thiess scope also included installing an air system that staged the release of oxygen into the combustion chamber to keep combustion temperature low and limit the NOx emissions. The boilers were fitted with limestone injection systems to ensure low SOx emissions. During 2010/2011, the Worsley MFCG project was the largest power project under construction in Australia, with job numbers peaking at 940. The Western Australian aluminium industry currently contributes $3.2 billion to the State s economy each year. Declared a project of state significance, the Worsley expansion project is expected to inject a further $1.2 billion annually.
