World's First LDES Industrial Park Launches in Heze, Aiming for 30GWh Cells & 20GWh Systems
On August 7, the first products rolled off the line at the world's first integrated industrial park dedicated to long-duration energy storage (LDES), located in the Luxi New Area of Heze, Shandong, developed by a leading Chinese storage battery maker. With a total planned investment exceeding RMB 13 billion across the full chain and a site of roughly 1,200 mu, the park spans LFP storage cell manufacturing, module and system integration, new materials and upstream raw materials, targeting 30GWh of 1175Ah LDES cells and 20GWh of 6.25MWh systems at full capacity — over 70% earmarked for overseas markets. Equipped with the company's Gen-5 smart production lines, the site is the industry's first to break 15GWh per line, cutting per-GWh investment by 32%, labor input by 58% and manufacturing energy by 13%, while doubling production efficiency versus its Gen-4 plants. The debut 1175Ah cell offers over 11,000 cycles and energy density above 180Wh/kg, covering 4–8 hour LDES scenarios; the company's order book is already filled through 2027.
