- Project PartnersVictorian GovernmentThis battery project was completed on 30 January 2022.
The Gannawarra Energy Storage System (GESS) is a 25 megawatt (MW)/50 megawatt-hour (MWh) lithium-ion battery to be co-located with the 60 MW(DC) Gannawarra Solar Farm located west of Kerang in north western Victoria.
It is being developed and financed by Edify Energy in a consortium with Wirsol Energy as co-investors, Tesla as battery provider, RCR Tomlinson as EPC contractor, EnergyAustralia as long-term operator, and ARENA and the Victorian Government as providers of grant funding.
How the project works
This Gannawarra Energy Storage System project will demonstrate how an existing solar farm can be retrofitted with battery storage. The battery will store energy at times of relatively low value. The battery will use stored energy and use it at times of relatively high value. The project will also examine providing other grid services such as frequency control ancillary services (FCAS) and, should it be established under the electricity market rules, a Fast Frequency Response (FFR).

Media Release: ARENA to Provide $25 Million to Jointly Fund Victoria’s First Large-Scale, Grid-Connected Batteries
The Australian Government through ARENA has announced it will match the $25 million by the Victorian Government to jointly fund Victoria’s first two large-scale, grid-connected batteries as part of the Victorian energy storage initiative.
Area of innovation
When complete, GESS will be:
- The first integrated renewables and battery system in Victoria and among the first in Australia;
- The first retrofit of a battery to an existing or under-construction solar farm; and
- Among the largest integrated renewables and battery systems in the world.
The battery will help demonstrate how large-scale batteries can provide different benefits to the electricity system, including improving grid stability and power quality, and how they can help integrate more variable renewable energy into the grid. For example, the battery could assist by reducing curtailment of future renewable energy generation on what is a relatively constrained line in the Victorian electricity system hence supporting higher levels of renewables in the region by reducing or controlling peak loading on these circuits.
ARENA and the Victorian Government will jointly provide $25 million in funding for both this project and the Ballarat Energy Storage System (BESS).
How are big batteries helping to transition to renewables?
Massive batteries are helping to keep the grid stable as more renewable generation comes online.
Solar battery storage in Victoria charging up for summer
Victoria’s two grid-scale batteries are up and running, ready to bolster the grid as temperatures rise and demand for electricity soars.
