Guangzhou Great Power Energy & Technology Co., Ltd. and Rept Battero Energy have both disclosed their financial reports for the first half of 2026. Driven by accelerating global energy storage adoption, Rept Battero’s H1 revenue surged up to 60 percent to top global residential storage cell shipments.
The latest interim disclosures from battery manufacturers underscore a structural pivot in the global energy market. While electric vehicle adoption rates see fluctuating momentum, stationary energy storage is expanding at a velocity that is catching even seasoned industry analysts by surprise. For supply chain managers and international investors alike, these financial results offer a clear window into where global capital is generating real returns.
Rept Battero’s Ascent to Global Residential Storage Leadership
According to preliminary earnings announcements, Rept Battero Energy generated between RMB 14.5 billion and RMB 15.2 billion (US$2.01 billion to US$2.11 billion) in revenue for the first half of 2026. This performance marks a year-on-year increase of 52.8% to 60.1%. Net profit attributable to shareholders reached an estimated RMB 700 million to RMB 850 million (US$97 million to US$118 million). Notably, these six-month figures already surpass the company’s entire full-year net profit of RMB 680 million for 2025.
Market research firm Xinluo Information confirms that the Tsingshan Holding Group-backed battery maker ranked first globally in residential energy storage cell shipments for the first half of 2026. It also secured second place worldwide in commercial and industrial (C&I) storage cell shipments. This dual milestone highlights a dramatic operational turnaround for a firm that reported a net loss exceeding RMB 2 billion as recently as 2024.
Here is why that matters: stationary storage is no longer just a secondary offshoot of the automotive battery sector. Data from the Gaogong Industry Research Institute (GGII) shows that China’s lithium battery storage shipments reached 630 GWh in 2025, growing 85% year-on-year—more than double the 35% growth rate recorded by EV batteries over the same period. By committing early capital to specialized manufacturing in Wenzhou and Jiashan back around 2020, Rept Battero positioned itself ahead of a massive demand curve.
Strategic European Standardisation and Margin Expansion
The company’s profitability turnaround rests on an early bet regarding international standardisation. As early as 2019, Rept Battero secured customized orders from leading European residential storage brands, helping establish a common cell specification for high-voltage systems across Europe. When geopolitical instability and soaring household energy costs triggered a European storage boom, the manufacturer was already deeply embedded in regional supply chains.
Total battery shipments reached 42.7 GWh in the first half of 2026, up 31.8% year-on-year. Energy storage battery shipments specifically grew 43.9% to 27.2 GWh, pushing related revenue up by 81.5%. As sales expanded and capacity utilisation improved, economies of scale became starkly evident. Gross profit rose by 138.8% year-on-year to 1.98 billion yuan (US$294.6 million), while net cash generated from operating activities jumped to 3.46 billion yuan (US$514.9 million).
