Goxia also delivered strong profitability. The annual net profit attributable to parent company shareholders hit RMB103 million, up 109.5% year-on-year. Most strikingly, net cash from operating activities exploded from RMB 3.73 million in 2024 to RMB 145 million—an almost 40-fold increase.
The company’s grid-scale solutions are primarily marketed under its ‘Hanchu ESS’ brand.
Financial summary (for the year ended 31 December)
On the gross margin front, despite widespread industry price-cutting, Guoxia lifted its overall gross margin from 15.1% to 18.6%—a 23.2% improvement—via agile cost controls. Its core energy storage system solutions segment delivered a gross margin of 20.1%, underscoring strong cost discipline and pricing power.
Business restructuring: utility-scale storage becomes the cornerstone
Revenue mix shifts reveal a successful strategic pivot from overseas residential storage to utility-scale storage as the core business.
Energy storage system solutions remained the primary revenue pillar, generating RMB1.814 billion in 2025—88.2% of total revenue. Large-scale/utility energy storage systems contributed RMB1.568 billion, soaring from 12.2% of total revenue in 2022 to 76.6% in 2025, cementing its status as the largest revenue driver.
By contrast, the European residential storage market—once the mainstay—fell slightly to 11.2% of total revenue, while Mainland China’s share remained stable around 79.27%.
Revenue by Geography (for the year ended 31 December)
The company is capitalising on policy tailwinds in China’s booming large-scale storage market. As China rolled out supportive renewable energy and storage policies, Guoxia swiftly repositioned itself, establishing dedicated teams to develop domestic utility-scale project markets and deliver sustained growth.
Meanwhile, engineering, procurement and construction (EPC) services emerged as a powerful new growth engine. In 2025, EPC revenue hit RMB174 million—soaring 790.3% year-on-year—lifting its revenue share from 1.9% to 8.4%.
To match explosive order growth, Guoxia accelerated capacity expansion. Annual energy storage system manufacturing capacity jumped from 1.56GWh in 2024 to 4.80GWh in 2025—a massive 207.5% increase. This scale-up ensures delivery capability for gigawatt-scale utility storage projects.
Looking ahead, the company plans to add multiple new production lines and testing systems, targeting an extra 6.0GWh of annual capacity for utility and C&I storage systems and 240,000 additional residential storage units (≈900 MWh) by the end of 2027.
This aggressive expansion supports current demand and prepositions Guoxia for the “AI + Energy Storage” boom. As AI data centers demand ultra-stable power, energy storage firms with large-scale delivery capacity will become critical, scarce partners.
