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.
