Jinko ESS Delivers 476MWh of SunTera System to Northern Jiangsu PV-Storage Project

Jinko ESS, a global leading energy storage company, has successfully delivered 476MWh of its SunTera G2 5MWh liquid-cooling systems as the first batch under a 1GWh PV+storage framework agreement signed with a major customer in northern Jiangsu. Designed to support centralized PV power plants, the project leverages an integrated “solar + storage” approach to improve renewable energy consumption and enhance regional energy structure and reliability.

To address the comprehensive needs of centralized PV projects in northern Jiangsu for safety, cost-efficiency, and environmental adaptability, the SunTera G2 system features an industry-leading liquid thermal management system that keeps cell temperature differences within 2.5°C. It also includes five-layer protection across the battery, module, rack, container, and system levels, providing strong resilience against high humidity and temperature fluctuation. With a 94% RTE and lifecycle exceeding 8,000, the system delivers high-performance output and optimal economic value. It supports the establishment of a stable, efficient, and secure clean energy supply system and accelerates the region’s energy transition.

“This marks a major step forward for Jinko ESS in scaling up solar-plus-storage applications,” said Damon Duan, General Manager of Jinko ESS China. “Energy storage plays a vital role in shaping the new energy landscape. With its safety, efficiency, and intelligence, the SunTera G2 is becoming a preferred choice for utility-scale energy projects. We will continue advancing our R&D efforts to provide tailored storage solutions for utility-scale PV and other major energy applications.”
