This is the final knowledge sharing report for the Gannawarra Energy Storage System (GESS). It outlines the performance and key learnings over the first 24 months of operation.
GESS is a 25MW / 50MWh battery that is integrated with Victoria’s first large-scale solar farm – GSF (being a 50MWAC solar farm). GESS was developed and structured by Edify and financed by ARENA and DELWP as providers of $25 million in grant funding with Edify in a consortium with WIRCON as 50-50 joint venture co-investors. Tesla was the battery provider, RCR the EPC contractor and EnergyAustralia is the long-term operator of GESS under a novel BSSA.
