According to EnergyTrend, Sigenergy has stepped up its activities in the energy storage sector recently. Since March, the company has made simultaneous efforts across four core areas—capacity expansion, technological and product upgrades, overseas orders, and capital strategy—with a series of key breakthroughs.
On March 13, Sigenergy’s Nantong Smart Energy Center was officially inaugurated. With a total investment of 500 million yuan and a floor area of 136,000 square meters, the center can produce over 300,000 units of inverters and energy storage PACKs per year, making it one of the world’s largest distributed energy storage plants under a single roof.
The Nantong Smart Energy Center has a planned capacity of 26 GWh and an automation rate of 95%. One energy storage PACK rolls off the production line every 15 seconds, and one inverter every 21 seconds, with a product yield rate of 99.9%.
Following the successful launch of Phase I, Sigenergy has also kicked off planning for Phase II of the center, which involves an investment of over 1 billion yuan and will add an extra 20 GWh of capacity, further strengthening its global delivery capability.
While ramping up production capacity, Sigenergy has also achieved remarkable progress in products and market expansion.
On the same day as the inauguration of the Nantong Smart Energy Center, Sigenergy launched its “AI in All” strategy, integrating artificial intelligence into products, manufacturing, and energy management, while improving production coordination efficiency through its self-developed MES system. The company also unveiled new energy storage products covering residential, C&I, and utility-scale scenarios, enriching its product portfolio.
On the same day, Shanghai Sigenergy Source Intelligent Technology, a wholly-owned subsidiary of Sigenergy, won the battery container bid for the Duqm Energy Storage Project of Oman’s national grid. With a scale of 500MW/2000MWh, the project stands as a flagship large scale electrochemical energy storage initiative in the Middle East. This win marks Sigenergy’s official entry into utility scale grid side energy storage, expanding its business from residential and C&I storage to full scenario energy storage solutions.
EnergyTrend believes that Sigenergy’s accelerated full scenario layout aligns with the industry’s development trend: “utility scale storage leading, residential storage coordinating, and C&I storage breaking through”. The company is well positioned to gain an edge as industry concentration rises.
In terms of capital strategy, on March 9, Sigenergy submitted its application for a mainboard listing on the Hong Kong Stock Exchange for the third time, with CITIC Securities and BNP Paribas as joint sponsors.
The prospectus shows strong growth in recent years. In 2023, the company recorded revenue of 58 million yuan, which surged to 1.33 billion yuan in 2024, representing a year on year increase of 2193%. In the first three quarters of 2025, revenue reached 5.641 billion yuan, up 692% year on year, with net profit of 1.89 billion yuan.
Overseas, in February, Sigenergy’s C&I energy storage inverters obtained Australia CEC certification, officially entering Australia’s C&I energy storage market. To date, Sigenergy has established a presence in more than 80 countries and regions, partnering with 161 distributors worldwide.
Overall, Sigenergy’s recent moves have further strengthened its layout in production capacity, product lines, and market structure. With capacity gradually coming online, listing procedures advancing, and technologies continuously implemented, the company’s competitiveness in the global energy storage market is expected to grow significantly.
