Trina Storage has released independently verified operational data from a 150MW utility-scale agrivoltaic + storage project, confirming strong real-world performance in both efficiency and long-term reliability.
The Feicheng project, part of a solar + storage hybrid renewable energy installation, has been in continuous operation for over a year, with performance evaluation conducted by UL Solutions and China’s Quality Certification Center (CQC). Results show that the system has consistently achieved 95.2% DC-side efficiency and 87.1% system-level round-trip efficiency, placing it among the most efficient large-scale energy storage systems currently in operation.
The project is powered by the company’s Elementa Series, a smart, flexible energy storage solution based on its proprietary in-house battery cells. Designed for flexibility and scalability, Elementa delivers high efficiency, safety and long-term reliability by optimizing performance across the entire system, from cell to grid.
After more than a year in operation, the system retains 98% of usable capacity, indicating minimal degradation and strong cycle performance. This long-term reliability supports a 15–20% reduction in Levelized Cost of Storage (LCOS) compared to industry averages, enhancing project bankability.
With its high efficiency and stable performance, the system enables participation in multiple market applications, including energy arbitrage, frequency regulation and reserve services, helping operators diversify revenue streams and shorten investment payback periods.
“Over the course of the past year, UL Solutions has conducted a rigorous evaluation of the project, based on strict performance standards,” commented Chen Chi, product manager at UL’s Energy and Industrial Automation group. “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, added: “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.”
