Recently, LONGi has been making frequent moves in the energy storage sector. From the successful grid connection of its first integrated storage project in the European market to the establishment of a new wholly-owned subsidiary in China, the company is clearly demonstrating its strategic ambition in the energy storage track.
LONGi’s First Integrated Storage Project in Europe Successfully Connected to the Grid in Italy
Marking LONGi’s "debut" in the European energy storage market, an integrated energy storage project located in Italy was recently successfully connected to the grid and put into operation.
The project features a 13.75MW / 50.16MWh energy storage system operating in synergy with a 35MWp photovoltaic power plant. LONGi not only provided a comprehensive integrated solution ranging from core storage equipment to system-level control but also offered full-cycle technical support under a Long-Term Service Agreement (LTSA). This support encompasses equipment maintenance, performance monitoring, and emergency response services.
Establishing "Yuanchu Weilai" New Energy to Expand Business Horizons
While deploying in overseas markets, LONGi is also steadily advancing its domestic energy storage assets and operational services.
On April 15, Yuanchu Weilai (Guangxi) New Energy Co., Ltd. was officially established. According to equity data from Qichacha, the company is indirectly wholly-owned by LONGi Green Energy.
The core business scope of the new company is extensive, covering multiple dimensions including energy storage technical services, contract energy management, wind power technical services, and solar power technical services.
Since LONGi’s acquisition of CleanTech, it has established several energy storage subsidiaries and launched three major products—OneBank 2.0, OneMatrix 2.0, and Hi-MO One+EnergyOne—covering all application scenarios such as large-scale utility plants and industrial/commercial sectors.
According to incomplete statistics from TrendForce, LONGi’s accumulated energy storage orders have exceeded 1.6GWh since the beginning of 2026.
Conclusion
Taken together, from the delivery, grid connection, and long-term maintenance of overseas equipment to the expansion of the domestic market, LONGi’s energy storage business has entered a stage of substantive, large-scale realization. It is gradually becoming a new pillar of business growth for the company as it navigates the cyclical fluctuations of the photovoltaic industry.
