The University of Adelaide engages TEC-C for Early Design Works of the Solar, Batteries and HV Upgrade project at Roseworthy Campus


The University of Adelaide selected TEC-C as the preferred tenderer after participating in a competitive tender process for the EPC of the Roseworthy Solar, Batteries and HV Upgrade project.

Due to the complex technical requirements of the project that included several cutting edge technologies, such as the implementation of Vanadium Redox Flow Batteries and the required budget, it was necessary to undertake some specific Early Design Work to refine the scope and specification of the project, to meet some particular requirements:

  • Ensuring to meet the project’s business case,
  • Quality of Energy Supply;
  • Research incentives; and,
  • Grant funding requirements.


The University of Adelaide engaged TEC-C to undertake Early Design Work that established innovative solutions to meet these requirements. Initially, the project’s scope considered a 500kWh/2MWh flow battery, pushing the limits of commercially available technologies that would meet this requirement, as well as providing a tangible Return on Investment, with associated operational cost savings.

TEC-C came up with a hybrid approach of implementing two types of battery technologies, with a smaller 100kW/400kWh flow battery to be able to research this new technology, in addition to a larger 300kW/1,200kWh lithium-ion battery. This updated configuration would allow the whole system to achieve a lower levelized cost of energy, implementing other related energy management experiments at a larger scale, operating the campus in a microgrid scenario. TEC-C’s team of engineers and finance specialists optimised the sizing through techno-economic modelling.

As part of the scope, the additional advanced concept design work, especially around the brownfield works for the new 11kV high-voltage network, allowed to significantly reduce project risks, providing higher certainty for lower costs, with an optimisation of the overall design of the system to be implemented, integrating solar, the two types of battery and the microgrid system.
