Future project

About

The Wallgrove battery is the first grid-scale battery in NSW that will pilot the use of synthetic inertia as a network service.

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 will offer energy and FCAS market services that generators need 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. 

The battery will also be used by Infigen Energy who will have 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 will be 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.

Project benefits

The battery will provide a new source of system stability services.

Finding lowest-cost ways to maintain frequency, while also increasing the supply of dispatchable power to the market, puts downward pressure on energy bills.

The trial will provide valuable technical and economic insights which will be shared across the energy industry – helping to identify the lowest cost technologies for future network needs.
