AGL’s $45 million co-generation facility in Altona is now open. The plant will provide an energy efficient supply of electricity and steam for Qenos, Australia’s sole polyethylene manufacturer.
Built, owned and operated by AGL’s Energy Services business unit, a team focused on improving the energy productivity of its commercial and industrial customer base, the plant will cut carbon dioxide emissions by 100,000 tonnes per annum, equivalent to taking 25,000 cars off the road.
The embedded plant has a nominal capacity of 21 MW and will produce 171 GWh annually, which is enough electricity to power more than 30,000 households. This, coupled with a heat recovery steam generator, produces up to 88 tonnes of steam per hour.
Michael Fraser, AGL Managing Director and CEO, said the facility was the largest investment in industrial or manufacturing co-generation in more than 10 years.
“This project has taken advantage of AGL’s strong position in the gas industry. It has also utilised the skills of our dedicated team of 65 plus engineers and technicians in AGL Energy Services, who are devoted to our industrial and commercial customers’ energy efficiency,” Mr Fraser said.
“AGL is well placed to assist the manufacturing industry, through its Energy Services business, to develop co-generation plants. These provide the biggest potential for manufacturers to reduce greenhouse gases and improve energy efficiency.”
Jonathan Clancy, Chief Executive Officer, Qenos said: “This project is a further demonstration of the cooperation achieved between industry, government, employees and the community to provide a secure and long term energy source, and improve the economics associated with the production of polyethylene. This is an investment in real sustainability.”
In 2012, AGL and Qenos were jointly awarded the “Best Co-Generation Project” at the Energy Efficiency Council industry awards.
• The co-generation facility, operated and maintained by AGL Energy Services, includes a Solar Titan 250 gas turbine package, with the latest combustion technology and heat recovery steam generator.
• The steam generator produces steam by recovering the exhaust heat generated by the gas turbine. The facility has the capacity to produce 21 MW of electricity, improving the customer’s carbon footprint and providing greater certainty of electricity supply, and generates up to 88 tonnes of steam per hour.
• The facility supplies up to 171 GWh of electricity to the site annually with the excess electricity being exported to the grid. All steam generation is used by the plant.
• The facility generates electricity at a lower greenhouse gas emissions intensity than the average emissions intensity of generators in the National Electricity Market. Further savings are achieved because all waste heat from the gas turbine is used to produce the steam required by Qenos, saving the need to install separate gas fired boilers. With the facility supplying most of Qenos’s electricity needs, it is estimated that overall greenhouse gas emissions will be reduced by approximately 100,000 tonnes per annum.
• AGL and Qenos 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 co-generation plant and balance of plant is estimated to consume approximately 4.5 petajoules of natural gas per annum.
