  • Distributed Generation in Australia: A Status Review 2011
    • University of Technology, Sydney

    This report was undertaken for the Australian Alliance to Save Energy. It includes case studies on a cogeneration plant at the Crown Casino in Melbourne and a bio-energy plant. Electricity generation was a big advantage when planning the Casino, due to the high load of the complex. Cogeneration has proven a cost-effective way to provide energy for the site, including waste heat for hot water and steam. While a 3.9 MW cogeneration plant was installed at Earthpower’s food waste to energy facility in Sydney to produce biogas from municipal, commercial and industrial food waste. Electricity generated from these plants is considered renewable under the MRET scheme, and is sold as eligible renewable energy, and is also eligible for the NSW Greenhouse Gas reduction scheme.

  • Macquarie University saves with cogeneration (Opens in a new window)

    Macquarie University had to replace the 30-year-old chiller running their library’s air-conditioning system. The university seized the opportunity to examine the cost of cogeneration and discovered that they could shave $20 million off their energy bill over the next 23 years.

  • Innovative gas-fired cogeneration on display at Griffith Hospital 2003 (Opens in a new window)

    When Griffith Hospital closed down its laundry and catering services, the hospital was left with a central steam plant working under capacity. Griffith Hospital installed an innovative gas-fired cogeneration system which will reduce its energy bills by $140,000 each year and cut greenhouse gas emissions by over 1,000 tonnes per year, the equivalent of taking 240 cars off the road.

  • CSR – Pioneer II Cogeneration Case Study 2012 (Opens in a new window)
    • Clean Energy Council

    Pioneer Mill incorporates a technology that allows the mill to operate under normal sugar operations whilst exporting electricity in a cleaner and more efficient way than in the past. Greater heat efficiency is achieved through electrification of the milling tandem, removal of smaller steam turbines around the boilers and new evaporator designs. During cogeneration operations steam from the backpressure turbine is used for sugar processing.

  • Energy Saver Cogeneration Feasibility Guide 2013 (Opens in a new window)

    This resource provides a guide and a tool to help companies decide if cogeneration is suitable for their site. The guide includes practical information about on-site cogeneration projects and a detailed step-by-step guide to assist companies to evaluate the financial viability of an on-site cogeneration system. The guide is aimed at asset/facility managers and is for sizing small to medium on-site cogeneration systems (up to 5 MW).

  • Energy Saver Co-generation Feasibility Tool 2013 (Opens in a new window)

    This tool gives users an understanding of their electrical and thermal loads and how much energy is consumed at a site level. The tool generates analysis to help users identify the most appropriate plant size for a site. It also provides financial information, including energy price scenarios and cash flow analysis, to help determine a business case.
