Trina Storage Exhibits Remarkable Performance in Energy Solutions
Independent testing confirms 95.2% DC efficiency and 98% capacity retention after one year of operation
Trina Storage has released independently verified operational data from a 150MW utility-scale agrivoltaic and storage project. This confirms the company’s strong performance regarding efficiency and long-term reliability in real-world conditions.
Independent Verification Establishes Performance Standards
The project is part of a hybrid renewable energy installation that combines solar and storage solutions. It has maintained continuous operation for over a year. The evaluation of its performance was executed by UL Solutions alongside the China Quality Certification Center (CQC), leading third-party authorities recognized globally.
According to the results, the energy storage system consistently achieved a remarkable 95.2% DC-side efficiency and an 87.1% system-level round-trip efficiency. This level of efficiency positions Trina Storage among the most effective large-scale energy storage systems currently operational.
Cutting-Edge Technology for Enhanced Reliability
The system utilizes Trina Storage's Elementa Series, a highly efficient and versatile energy storage solution designed and constructed with proprietary in-house battery cells. This design focuses on flexibility and scalability, ensuring that the system achieves high efficiency and long-lasting reliability across its performance spectrum—from the battery cell stage right up to the grid level.
Among its key features, the system integrates a smart thermal management apparatus that minimizes cell temperature variation to within 3°C. Additionally, the auxiliary power consumption remains impressively low at 1.8%. Collectively, these functionalities significantly reduce energy loss—by approximately 30% in contrast to conventional systems. Therefore, the project contributes around 200,000 kWh of extra electricity annually, further enhancing overall output and revenue potential.
Long-Term Economic Benefits
Having been operational for more than a year, the system maintains 98% of its usable capacity. This remarkable retention signifies minimal degradation, affirming solid cycle performance. Customers benefit from a reduction of 15-20% in Levelized Cost of Storage (LCOS) when compared to industry averages, which substantially enhances the project’s bankability.
The system’s high efficiency and dependable performance facilitate participation in various market applications, including energy arbitrage, frequency regulation, and reserve services. These features allow operators to diversify their revenue streams and decrease investment payback periods, thereby bolstering overall financial health.
Insights from Industry Experts
“Over the course of more than a year, UL Solutions conducted a rigorous evaluation of the project based on strict performance standards,” stated Chen Chi, product manager in the Energy and Industrial Automation group at UL Solutions. “The system has consistently shown optimal efficiency and cycle life, alongside low auxiliary power consumption throughout the monitoring period. These outcomes indicate a solid level of technical integration and reliable performance in real-world conditions.”
Shawn Deng, the Head of Global Product & System Integration at Trina Storage, commented: “We’re proud to see our technology delivering real value under field conditions.
