It is essential that CSU lead by example
and continue to address sustainability
“ ”
Sustainability at CSU is everyone's business
“ ”Professor Andrew VannVice Chancellor and President
THE IDEA
Cogeneration energy has been explored as a sustainability project at CSU since 2010.
By the following year, CSU identified that the centralised hot water system at CSU in Bathurst, which supplies hot water and heating for a large proportion of the campus, was a potential site for the installation of a cogeneration system.

In addition to energy savings, cogeneration also appealed because of its financial viability and the robustness of its technology.
THE JOURNEY
Investing in sustainability projects to achieve CSU’s energy reduction targets is a rigorous process designed to ensure CSU receives value for money for the goods and services procured.
INVESTING IN SUSTAINABILTY PROJECTS AT CSU
EQUALSVALUE FOR MONEYFOR GOODS AND
SERVICES PROCURED
In the case of cogen at CSU, some 12 months of data logging to develop a model of energy demands and a year’s worth of 30-minute interval energy consumption data for the campus was developed and analysed before the project was deemed to be viable. The data was needed to determine the best size cogeneration system for CSU’s needs.
The forecast energy and cost savings developed were also used to aid in understanding potential risks of the investment under a range of scenarios.
CSU engaged an external consultant to assist with the feasibility assessment and development of a technical specification.The project was tendered and at the end of the process the CSU cogeneration contract was awarded to Clarke Energy Australia to install a 637kW system.
The manufacturing and delivery of the system to Bathurst took three months. The 22-tonne system was custom-made in Austria, transported to Hungary where it was fitted into a soundproof enclosure….

and then shipped to Australia
It arrived in Bathurst in April 2014. On-ground specialist staff in Bathurst worked on setting up the plant and configuring it to campus systems.
HOW IT WORKS
THE BENEFITS
Cogeneration energy will drop CSU's total carbon footprint by about seven per cent
Cogen energy will provide power and hot water to CSU buildings
Cogen works towards CSU's commitment to achieving sound sustainability outcomes
Cogeneration energy will power about 65 per cent of CSU's Bathurst campus
Forecast savings for CSU in Bathurst after converting to cogen:
