The Sapphire Solar Farm – Battery Energy Storage System is a 50,000kW energy storage project located in Glen Innes, Inverell, New South Wales, Australia. The rated storage capacity of the project is 100,000kWh.

The project was announced in 2017 and will be commissioned in 2021.


The Sapphire Solar Farm – Battery Energy Storage System is being developed by CWP Renewables Pty. The project is owned by CWP Renewables Pty (100%).

The key applications of the project are renewables capacity firming and renewables energy time shift.

Contractors involved

CWP Renewables Pty is the owner. CWP Renewables Pty is the developer.

Additional information

CWP is currently building the 270 MW Sapphire wind farm, helped by a contract for part of the output from the ACT government, and in 2018 is looking to begin construction of a 170MW solar farm, along with 50MW/100MWh of battery storage. The projects will depend on contracted off-take agreements for at least part of the project. The Sapphire wind farm has a 20 year contract for 100MW with the ACT government (at $89/MWh fixed), but the remainder will go “merchant”. The solar and storage facilities could follow the same blueprint.
