- Cunderdin combines 128 MWdc of solar with 220 MWh of battery storage to supply the SWIS grid.
- It uses 80 PowerTitan units with liquid cooling, AI monitoring, and a modular design for efficient, safe performance.
- Delivers frequency and voltage support while storing excess solar power for peak demand periods.
The Cunderdin solar-storage hybrid project has entered full commercial operations, setting a new benchmark for clean energy integration in Australia.
Global Power Generation Australia developed the facility, which combines 128 MWdc of solar power with 220 MWh of battery storage. Sungrow Power Supply Co., Ltd. led the design, equipment delivery, grid integration, and commissioning of the project.
The project sits in the Wheatbelt region and connects directly to the South West Interconnected System (SWIS), the primary power grid for southwestern Australia. The development team completed commissioning tests in March 2025 and officially launched the project in early April.
The system uses a fully DC-coupled architecture. The solar panels connect directly to the batteries, eliminating the need for alternating current (AC) conversion. This design reduces energy loss and improves efficiency. It also allows the system to store excess solar energy and dispatch it during periods of high demand.
Sungrow installed 80 PowerTitan units on-site. Each unit features liquid cooling, modular components, and AI-driven cell-level monitoring. These technologies improve safety, simplify maintenance, and support long-term performance.
The hybrid system provides critical grid services, including frequency regulation and voltage control. These services help the SWIS manage the challenges of variable solar generation. The facility also improves real-time energy management, giving Australia’s wholesale electricity market greater flexibility.
Joe Zhou, Country Director at Sungrow Australia, emphasised the company’s role in delivering large-scale, tailored solutions. “This project reflects our commitment to delivering robust technical solutions tailored for large-scale networks,” he said.
Global Power Generation included the Cunderdin project in a broader strategy to expand energy infrastructure across Australia. The hybrid model demonstrates the potential for integrating renewables into complex grid systems with high reliability.
The project avoids curtailment by storing surplus solar energy and shifting delivery to match grid demand. It supports peak load management and boosts the grid’s dynamic response, positioning the facility as a key contributor to Australia’s clean energy transition.
Sungrow’s technical leadership and Global Power Generation’s investment strategy brought the project to life. The companies aimed to demonstrate how hybrid systems can overcome challenges related to renewable energy variability.
The Cunderdin hybrid plant now stands as a flagship for clean energy innovation. It showcases how advanced technologies and innovative design can stabilise grids, reduce emissions, and support long-term energy goals.
With the launch of this facility, Australia gains a critical tool for managing solar energy more efficiently. The success of this project signals new momentum for hybrid renewable solutions across the country.
The Cunderdin site strengthens the SWIS and adds value to the national electricity market. It sets a strong precedent for similar developments in the future, both in scale and technical execution.
