The facility represents Australia’s largest industrial cogeneration plant to be built in a decade, according to AGL.
At an approximate cost of $45 million, the plant will have a nominal capacity of 21 MW and when coupled with a heat recovery steam generator will produce up to 88 tonnes of steam per hour.
The embedded cogeneration facility is expected to reduce greenhouse gas emissions associated with the production of polyethylene at the Qenos plant by 100,000 tonnes of carbon dioxide per annum, the equivalent to taking 24,390 cars off the road.
“The replacement of one of our steam boilers with a 21 MW cogeneration plant will result in a significant improvement of our energy efficiencies,” said Qenos CEO Jonathon Clancy.

An existing steam boiler on the Olefins site at Altona will be decommissioned and replaced with a modern cogeneration unit. The cogeneration unit will meet all of Qenos’ electricity demand and will be capable of producing over a third of its steam requirements.
AGL will build the cogeneration plant for Qenos and the parties have entered into an Operating and Maintenance Agreement for the next 15 years, with options to extend to 25 years. AGL will also become the sole supplier of natural gas to the site to operate the gas turbine and balance of plant.
The cogeneration plant and balance of plant is estimated to consume approximately 4.5 petajoules of natural gas per annum, and is expected to begin operations in late 2012.
AGL’s EPC contractor for the project is UGL Limited and the turbine for the project will be provided by Solar Turbines International and supported by Solar's overhaul, parts, and service facility in Rowville, Victoria.
