Our investment

In our first investment in a standalone grid-scale battery, the CEFC committed up to $50 million to enable the expansion of the Hornsdale Power Reserve from its initial 100 MW capacity to 150 MW. Leading French renewable energy provider Neoen owns and operates the Hornsdale Power Reserve, which also attracted investment from ARENA and the South Australian Government.

Energy storage supports cost effective, reliable, clean electricity and is a key component of Australia’s transition to a low emissions economy. Large-scale batteries can help electricity networks support a higher penetration of cleaner, lower-cost renewable energy, while also delivering support to the grid at demand periods.
