Apart from the development and operation of wind and solar farms, the construction of hybrid power plants for off-grid industries is an important growth segment for juwi. In such projects solar or wind power plants are complemented with storage units.
To date juwi has developed hybrid solutions with renewable energy for three Australian customers: For the gold and copper mine DeGrussa, the mine Agnew and a research center on Heron Island. The fourth appointed hybrid project will be realised to secure the electricity supply for the town of Esperance.
In 2017 juwi installed the worldwide largest solar hybrid system at the time, for the DeGrussa coppermine in the west of Australia. The system reduced the CO2 emissions of the mine by 12,000 tons per year and saved an annual diesel consumption of 5,000,000 liters.
juwi built a high-performance solar battery system for a research station of the University of Queensland, on the Heron Islands, in the southern area of the Great Barrier Reef. Since the middle of 2019, the hybrid system provides more than 80 per cent of the electricity demand of the station.
juwi built a 4 MW solar power plant including a cloud forecasting tool and a high-performance microgrid control for the Agnew Goldmine in the west of Australia. The fully integrated hybrid solution will improve the reliability of the electricity supply, reduce operating expenses and decrease the environmental impact of the mine.
Currently in planning: juwi will construct a wind and solar farm for the electricity supply of the town Esperance in the west of Australia. The hybrid project consists of a 4 MW solar plant, two 4.5 MW wind turbines and a lithium-ion battery storage system, all of which will be synchronised with the existing gas generators.
