Maxxen Energy Opens Large-Scale BESS Manufacturing Facility in Turkey
Maxxen Energy has inaugurated an automated factory in Aydın, Turkey, dedicated to the production of utility-scale Battery Energy Storage Systems (BESS). The facility, a subsidiary of Kontek Energy, manufactures containerized solutions utilizing Hithium LFP cells. With an annual capacity of 5 GWh, Maxxen targets the European and Middle Eastern markets, having already sold 664 MWh across projects in its first nine months of operation.
Maxxen Energy, a subsidiary of the Turkish renewable energy specialist Kontek Energy, has inaugurated a new factory in Aydın, Turkey, dedicated to the production of utility-scale Battery Energy Storage Systems (BESS). The 20,000-square-meter facility, which commenced operations in 2026, focuses on assembling containerized solutions for the European and Middle Eastern markets.
The factory primarily produces its 5 MWh DC Box container and offers an optional MV Power Station, the MV Box, with power outputs of 2.5 MW, 5.0 MW, or 10 MW. The plant's nameplate capacity is 5 GWh per year, with current utilization at 1.5 GWh per year. In its first nine months of 2026, Maxxen has already sold 664 MWh across 21 global projects.
Production relies on a partnership with Chinese battery cell and ESS manufacturer Hithium, which supplies 314 Ah LFP cells. These cells, each approximately 1 kWh, are assembled into modules and then integrated into containers at the facility. Maxxen has announced plans to transition to using 587 Ah cells by the end of 2027. The facility represents a $35 million investment designed to supply utility-scale projects.
The manufacturing process is highly automated, utilizing KUKA robotic arms for picking and placing cells and modules. Assembly involves four main stages: cell pre-charging and testing, robotic stacking and laser welding, liquid-cooling setup, and final container integration and load testing. Safety is a key focus; in the event of a cell fire, a clean room can be evacuated of oxygen within 100 seconds.
To mitigate maritime shipping delays, Maxxen maintains a 200 to 250 MWh warehouse buffer stock of battery cells and raw materials on site. This enables the company to offer deliveries within one to two weeks by truck across mainland Europe. Maxxen has captured an estimated 5% market share in its European target segment during its first nine months of operation. According to Ruben Valiente, Maxxen’s Managing Director, the company has
