Wattle Creek Energy Hub
ABOUT THE PROJECT
The Wattle Creek Energy Hub is a proposed project to be located on land owned by the University of Sydney, east of Big Hill in the NSW Southern Tablelands of NSW.
If approved, the Wattle Creek Energy Hub could generate up to 500 megawatts (MW) of electricity from the sun and wind, providing enough clean, reliable energy to power around 170,000 households per year while offsetting the emissions of around 950,000 tonnes of carbon dioxide. The proposal also includes the installation of a large-scale battery with a capacity of up to 700 megawatt hours (MWh) of electricity, which would be dispatched on command to provide a range of network support services.
The proposed site is situated east of Big Hill, approximately two hours’ drive from Sydney. The proposal is strategically positioned to make use of an existing high voltage substation, located adjacent to the property, to deliver clean, renewable energy from the energy hub to the University, local electricity users and the rest of NSW.

Developer
The proposed project is being developed by Spark Renewables, one of Australia’s leading developers and long-term owner and operators of renewable energy generation assets. Spark Renewables is a part of the Spark Infrastructure Group, one of Australia’s leading investors in critical energy infrastructure assets. Read more about us and our team.
PARTNERSHIP WITH THE UNIVERSITY OF SYDNEY
Involvement of the University of Sydney

The University of Sydney selected Spark Renewables to investigate and develop a hybrid renewable energy facility on the University’s Arthursleigh property, located in the New South Wales Southern Tablelands.
The University of Sydney is a New South Wales State Government-owned tertiary education institution, engaged in the provision of tertiary education and research. As Australia’s first university – founded in 1850 – the University of Sydney has a proud history of global leadership in education and research and inspiring people from all backgrounds to contribute to positive real-world change.
University of Sydney Pro-Vice Chancellor (Research – Enterprise and Engagement) Professor Julie Cairney said:
“This long-term partnership with Spark Renewables will support a research program and infrastructure for the translation of research into innovative renewable energy technologies. New clean energy products and knowledge will benefit Australia’s environment and the economy. We look forward to a long and successful partnership.”
Research opportunities
A key element of the proposed energy hub is a two acre “test-bed facility”, which would enable the University of Sydney to undertake research on new and emerging technologies, including further testing of innovative battery systems developed by Gelion, a company spun out from the University in 2015.
Spark Renewables and the University have also agreed to an ongoing research agreement throughout the life of the energy park, collaborating on initiatives related to clean energy in the fields of science, engineering, business and economics. The proposed partnership will also include a work experience and placement program for undergraduate and PhD students.
