This case study examines system integration of solar and storage in Western Australia. The AU$40 million (US$30 million) DeGrussa Solar Power Project is owned by France-based renewable energy firm Neoen, while German solar specialist juwi Group was responsible for development, EPC and O&M. By installing a 10.6MW solar PV plant and a 6MW battery storage system, diesel consumption can be reduced throughout the day and to some extent after the sunlight begins to dwindle.
