Sungrow Collaborates with Zenith Energy to Power Australia's Largest Off-Grid Hybrid Project

Australia's mining sector continues to play a vital role in the economy, contributing 10-11 percent to the nation's GDP and generating a record USD 455 billion in export revenue in 2022-23, according to the Australian Bureau of Statistics. Kathleen Valley, located in a remote region of Western Australia, is far from an established power infrastructure but rich in abundant mining resources, utilizing off-grid energy solutions essential for reliable and continuous mining operations.

The renewable off-grid solution will reduce reliance on costly and polluting diesel fuel, lower greenhouse gas emissions, and cut energy costs. As Australia moves toward sustainable practices, it also helps mining companies comply with stricter environmental regulations and enhance the overall sustainability of their operations.

This project features an advanced hybrid power system that integrates 17 MW / 20 MWh of battery storage, 17 MW of solar energy, and 30 MW of wind power. Additionally, the system includes 32 MW of thermal generation, comprising 27 MW of gas and 5 MW of diesel. The project applied Sungrow's SG350HX string inverter, SC4000UD-MV power conversion system, and ST2236UX PowerTitan liquid cooling energy storage system to provide a highly efficient renewable energy solution, supporting sustainability and energy optimization for mining operations.

These advanced systems have powered the entire site on 100 percent renewables continuously for three and a half days since being commissioned on 30 June this year. The system design will enable delivery of up to an 80 percent renewable energy fraction over the course of a year significantly reducing its carbon footprint and setting new benchmarks for environmentally responsible mining.

The country director of Sungrow Australia, Joe Zhou, said, "We are proud to collaborate with Zenith Energy and Liontown Resources on this transformative project. By integrating advanced renewable solutions, we are driving the mining industry's energy transition and demonstrating the power of sustainable innovation in one of Australia's key economic sectors."
