The Wallgrove Grid Battery is the first grid-scale battery in NSW and provides the use of synthetic inertia as a network service, fully operational as of December 2022.
These network services help to stabilise the grid, and will become increasingly integral to enable the increase of renewable generation to safely connect to the grid.
As well as grid-scale synthetic inertia, the battery offers energy arbitrage and FCAS market services that are needed to optimise and firm up energy supply. Research and results from the trial will be shared to support future projects and help demonstrate that battery technology is a low cost and technically viable solution to the emerging challenge created by the transformation of the generation sector.
Iberdrola Australia has dispatch control of the battery for energy arbitrage and Frequency Control Ancillary Services (FCAS). These uses are complementary to the network services and ensure the full capacity of the battery is optimally utilised – which helps provide network services at the lowest possible cost to customers.
The battery has been designed and constructed by Tesla using Tesla Megapacks, and connected directly to Transgrid’s transmission network.
The project has received funding from ARENA as part of ARENA's Advancing Renewables Program and the NSW Government as part of the Emerging Energy Program.
