Trina Storage opens second battery super factory, boosting production capacity to 25 GWh

Recently, Trina Storage’s second super factory officially commenced operations. This milestone marks another key step in the company’s “Cell-to-AC” integrated production ecosystem and drives steady progress toward achieving its 2025 delivery target of 8–10 GWh.

This facility, covering more than 14,000 m2, brings the company’s total product capacity to 25 GWh. It enables mass production of next-generation energy storage systems and 314Ah battery cells, including some of the industry’s first large-capacity cells, supporting the sustainable development of reserve projects exceeding 70 GWh.

According to InfoLink Consulting, global battery energy storage system (BESS) installations reached 86.7 GWh in the first half of 2025, representing a 54% year-on-year increase. In response to surging market demand, Trina Storage has taken the lead in upgrading its high-quality production capacity, driving industry transformation through enhanced intelligent integration and coordinated AC-DC synergy. Apart from its manufacturing facilities, the company has also established localized integration centers in China, Europe, and North America to deliver comprehensive lifecycle services to clients worldwide.

The first Super Factory has recently completed a comprehensive upgrade, achieving fully automated production from cell manufacturing to container integration, which has boosted overall efficiency by over 50%. An industrial IoT platform now integrates ERP and MES systems, establishing a comprehensive “human-machine-system” intelligent management framework.

Trina Storage’s headquarters houses a state-of-the-art system integration validation platform, featuring the industry’s first self-built 35 kV MW-scale power station, a 478 $m^3$ environmental testing chamber, MV PCS integration capability, and a 1:1 semi-physical EMS simulation platform. Following a four-level validation framework, the platform enables precise simulation of system efficiency and stability, mitigates risks in the early stages, and shortens overall delivery cycles.

The company recently secured a total of 2.48 GWh energy storage orders from clients across China, Latin America, and the Asia-Pacific region. In North America, cumulative shipments reached 1 GWh in the first half of the year, marking Trina Storage’s entry into the GWh-scale delivery era and further extending its global footprint across six continents.

With a solid global manufacturing network, intelligent production systems, and leading-edge validation capabilities, Trina Storage continues to accelerate its “Cell-to-AC” strategy and reinforce its position as a pioneer in the global energy storage industry. Moving forward, the company remains committed to driving technological innovation, advancing sustainable energy solutions, and empowering a cleaner, smarter energy future worldwide.
