Transgrid, the NSW-based transmission company providing the backbone to the country’s biggest state grid, has put out an urgent call for 10 giant spinning machines and 5 GW of battery storage to protect the heartbeat of the grid as it shifts to periods of 100 per cent renewables.

The latest assessment of system strength needs by Transgrid – revealed in its final regulatory document – signals a significant shift in its thinking about new technologies and their ability to replicate the critical system services traditionally provided by coal, gas and hydro.
