Trina Storage and North China Electric Power University Launch White Paper on Large-Scale Energy Storage Technology Applications and Industry Development

On September 26, 2025, the 2025 Large-Scale Energy Storage Technology Innovation and Application Seminar was successfully held at North China Electric Power University. During the event, Trina Storage and the university jointly released the White Paper on the Application of Large-Scale Energy Storage Technology and Industry Development (hereinafter referred to as the White Paper). This document focuses on the critical role of energy storage technology in energy transition and development opportunities, providing forward-looking insights to promote high-quality industry growth.

Jiang Zhiyi, the director of the Trina Storage Product Research Institute, delivered a speech titled “Ready for Storage: How Large-Scale Energy Storage Supports Energy Reform”. He systematically explained the core value of energy storage in building a new power system and highlighted the 6MWh+ coordinated solution for alternating current and direct current launched by Trina Storage. This solution achieves significant breakthroughs in system safety, lifecycle profitability, and adaptability across multiple scenarios, thereby aiding global energy transformation.

Jiang emphasized that against the backdrop of expanding renewable energy installations and ongoing electricity market reforms, the energy storage sector is undergoing a crucial transformation from being “policy-driven” to “demand-driven” and from “cost-oriented” to “value-oriented”. Notably, the recent national-level Special Action Plan for the Large-Scale Construction of New Energy Storage (2025-2027) has further clarified the direction of technological development and market applications in the industry. It has also set higher requirements for the safety and reliability of energy storage systems, synergy among generation, grid, load, and storage, as well as intelligent operation. Trina Storage is actively responding to these trends by continually advancing system capability upgrades.

To establish a comprehensive safety system from cell to system, Trina Storage is committed to the belief that “safety is the lifeline of energy storage”. They have built a multi-layered protection system covering cell materials, pack integration, and the entire system. At the cell level, high thermal stability cathode materials and optimized separator technologies have improved the cells’ heat resistance to 180°C. At the pack level, the use of flame-retardant materials, comprehensive temperature monitoring, millisecond-level fusing, and pack-level fire protection systems enable early suppression of thermal runaway. To validate the system’s reliability under extreme conditions, Trina Storage has conducted full-scale fire tests simulating the entire process from cell thermal runaway to open flame development. The results showed that the fire protection system can rapidly extinguish flames without re-ignition, meeting various international standards, including NFPA 855 and NFPA 69.

The explosion-proof and ventilation designs have also received third-party certification from Rhein, ensuring controlled pressure and flammable gas in the event of an accident. In terms of electrical safety, the system innovatively employs a three-tier electrical protection and multi-level isolation mechanism, combined with arc flash analysis to safeguard the equipment and personnel. Furthermore, Trina Storage has established a three-tier safety early warning platform that collaborates across cloud, edge, and terminal systems, covering key risk points such as insulation anomalies, voltage fluctuations, thermal runaway, and outlier cells. This enables comprehensive monitoring from device-level to cloud-level. Coupled with an AI big data panoramic monitoring platform, it can assess the health and predict faults of core equipment, achieving 24-hour dynamic operation and maintenance, effectively identifying potential hazards and providing early warnings, aligning with the requirements for the “AI+” integration applications stated in the Special Action Plan.

In addition to safety upgrades, the new generation system has also achieved significant improvements in economic efficiency. By incorporating 587Ah ultra-large capacity cells, the new 6MWh+ system has increased the energy density per cabin by 24.6%, effectively reducing land use and EPC costs. Combined with hybrid wind-liquid temperature control technology, a zero degradation design for the first year of the cells, a system efficiency of 96% (RTE), and a cycle life exceeding 15000 cls, the system’s lifecycle cost of electricity (LCOS) has decreased by approximately 12.5% compared to the previous generation, creating greater profit opportunities for participation in electricity market transactions.

Trina Storage is dedicated to validating and unlocking the value of energy storage across different application scenarios. They provide customized system configurations and scheduling strategies for complex scenarios such as large-scale renewable energy integration, independent shared storage, commercial and industrial parks, and overseas microgrids, ensuring efficient and stable operation throughout the project lifecycle. As of the first half of 2025, Trina Storage’s cumulative global shipments have surpassed 12GWh, with projects spanning multiple markets including Asia-Pacific, Latin America, Middle East and Africa, and North America, demonstrating excellent grid adaptability and local service capabilities. Notably, current overseas orders signed exceed 10GWh, expected to be delivered in 2025-2026, showcasing Trina Storage’s global leadership.

Looking ahead, Trina Storage will continue to leverage its industry synergy advantages, providing efficient, reliable, and intelligent energy storage products and solutions to empower large-scale applications in diverse scenarios. They will persist in driving the evolution of energy storage systems towards greater safety, economy, and intelligence, contributing to the formation of a new power system centered on renewable energy.
