The construction site in Queensland, Australia, is buzzing with machines, and large-scale construction equipment is entering in an orderly manner. The Lower Wonga integrated solar energy storage project in Australia is entering full operation. As one of the leading photovoltaic direct current coupling benchmark projects in Australia at present, the implementation and construction of this project not only fills the gap in the local power grid's new energy consumption, but also witnesses China's hard core energy storage technology crossing the ocean, adding a key weight to Guoxuan High tech's global new energy layout.

Empowering the Australian power grid upgrade

The Lower Wonga integrated photovoltaic and energy storage project, which is currently under construction, is located in Queensland, Australia. It is fully invested and developed by the internationally renowned comprehensive energy developer Lightsource BP. The overall plan is to build a 380MWdc photovoltaic power station, which will be accompanied by 281MW/843MWh energy storage systems. The energy storage scale ranks among the top tier of large-scale photovoltaic and DC coupling projects in Australia. The overall construction period of the project is steadily advancing, and it is expected to be completed and officially connected to the grid by the end of 2028.

After the project is fully put into operation, the clean energy supply capacity will be greatly released, and the annual power generation can stably meet the electricity demand of 126000 households in the local area for a whole year. On the one hand, it can continuously expand the total supply of clean electricity in the Australian national electricity market, and on the other hand, it can effectively alleviate the problem of local new energy grid connection, comprehensively enhance the regional new energy consumption capacity, consolidate the stability of the Australian power grid operation, and help steadily promote Australia's energy transformation work.

Cracking down on local industry pain points

As the core EPC contractor of the project, Guoxuan High tech provides a one-stop integrated solution for large-scale photovoltaic energy storage, covering the entire process of customized design of energy storage systems, supply of complete core equipment, overall system integration, on-site grid connection debugging, and other closed-loop services. It fully controls the construction quality and progress of the project. The project is equipped with Guoxuan High tech Qianyuan Intelligent Storage 5MWh energy storage system, combined with the company's independently developed long cycle battery cells, which can achieve long-term stable and safe operation for 25 years. At the same time, the entire product has successfully passed multiple international authoritative qualification audits such as IEC certification and Australian power grid access, fully adapting to the complex and changing operating conditions of the local power grid in Australia.

Based on the long-standing industry challenges in Queensland, such as photovoltaic curtailment and limited power generation, frequent voltage fluctuations in the power grid, and high project construction and operation costs, Guoxuan High tech has targeted and developed its own core technology for DC coupling. This technology can efficiently absorb surplus electricity from photovoltaic power generation, minimize photovoltaic power waste, and reduce abandoned solar losses. At the same time, the project optimizes the shared mode of optical storage equipment, simplifies the asset allocation structure, effectively compresses the initial investment cost in the early stage of the project, and comprehensively improves the operational efficiency of the entire optical storage system. In addition, the project adopts industry standardized prefabricated cabin structure design, combined with cutting-edge battery management technology, to accurately regulate the operation status of batteries, extend the service life of energy storage equipment, ensure stable output of grid connected power, fully comply with Australian electricity market supervision and operation standards, and take into account the economic and regional power supply safety of the project.

Accelerate global strategic layout

The successful commencement of the Lower Wonga integrated solar energy storage project is a milestone event for Guoxuan High Tech in deepening its cultivation of the high-end new energy market in Australia. Relying on its core competitive advantage in the complete lithium battery industry chain, Guoxuan High tech has achieved the full chain capability of independent research and development, large-scale production and manufacturing of energy storage core equipment, and integrated engineering project delivery for external output. It continues to implement the overseas model of Chinese technology+local landing, and carries out project co construction in accordance with the needs of overseas and local markets, gaining high recognition from leading enterprises in the global energy industry.
