Trina Storage has unveiled independently verified operational data from its 150MW utility-scale agrivoltaic + storage project in Feicheng, China, confirming robust real-world performance in both efficiency and long-term reliability. This significant milestone, evaluated by UL Solutions and China’s Quality Certification Center (CQC) after over a year of continuous operation, provides critical validation for large-scale hybrid renewable energy installations. The project's consistent achievement of 95.2% DC-side efficiency and 87.1% system-level round-trip efficiency positions it among the industry's leading energy storage systems, setting a high benchmark for operational effectiveness in the rapidly expanding global energy storage market.The Feicheng installation, a cornerstone of integrated renewable energy solutions, is powered by Trina Storage’s proprietary Elementa Series. This smart, flexible energy storage solution leverages in-house battery cells and is engineered for optimal performance from cell to grid, ensuring high efficiency, enhanced safety, and extended reliability. A key finding from the year-long monitoring period reveals that the system maintains 98% of its usable capacity, indicating exceptionally low degradation and strong cycle performance. This remarkable long-term reliability is projected to contribute to a 15–20% reduction in Levelized Cost of Storage (LCOS) compared to current industry averages, significantly improving project bankability and attractiveness for investors.The system's demonstrated high efficiency and stable performance unlock its potential for participation in a variety of critical market applications. These include energy arbitrage, where operators can capitalize on price differentials, as well as essential grid services such as frequency regulation and reserve capacity. Such versatility enables project operators to diversify revenue streams, enhance grid stability, and ultimately shorten investment payback periods, making large-scale energy storage projects more economically viable.Chen Chi, product manager at UL’s Energy and Industrial Automation group, underscored the rigor of the evaluation, stating, “Over the course of the past year, UL Solutions has conducted a rigorous evaluation of the project, based on strict performance standards. The system has consistently shown optimal efficiency and cycle life, and low auxiliary power consumption throughout the monitoring period. These outcomes indicate a solid level of technical integration and reliable performance under real-world conditions.”Shawn Deng, Trina Storage Head of Global Product and System Integration, emphasized the company’s commitment to transparency and performance. “We are proud to see our technology delivering real value under field conditions. From Cell-to-AC capability to third-party validation, our goal is to build trust through performance. We will continue working with global partners to test next-generation systems in diverse environments and provide transparent, data-driven benchmarks for the industry.” This independent verification provides crucial data for developers and investors, reinforcing confidence in the long-term viability and economic returns of advanced energy storage technologies.
