Energy storage to strengthen grid reliability in NSW

Transmission network service provider TransGrid is installing a 50MW / 75MWh grid-connected lithium ion battery at its Wallgrove substation in western Sydney.

The Australian Government is providing up to $11.5 million for the project through the Australian Renewable Energy Agency (ARENA). The NSW Government is funding a further $10 million through its Emerging Energy Program. 

The Hon Angus Taylor MP, Minister for Energy and Emissions Reduction, said projects like this are important to test the ability and associated costs of large scale batteries as a way to stabilise the grid. 

‘Energy storage is one of the priority technologies under our Technology Investment Roadmap but for batteries to play a role we must bring down the cost,’ the Minister said. ‘This project will test role and capability of batteries to bolster the grid, helping to improve the technology.’

ARENA CEO Darren Miller said, ‘Large scale batteries have a big role to play in firming and balancing our electricity system as we move towards a future energy mix with higher penetration of renewable energy.’
