The Hornsdale development should be a key example on the pros and cons of battery technology.

The Hornsdale project was developed in 2016/17 for $90m with a generation capacity of 315 megawatts, and a published capacity factor of approximately 40%. That implies average production of 125MW of electricity per day.

The 50MW battery extension at Hornsdale was a cost of $70m. At this cost 125MW battery storage costs $175m. With the $90m development of Hornsdale, guaranteed next day production of 125MW totals $265m.

As Ash pointed out, renewables producer IFN paid $60m for Visy's 125MW fast start powerplant to provide firming capacity to it's renewable generation.

This should demonstrate the economics of gas providing a low cost transition for renewables.
