JinkoSolar will supply a two-hour liquid-cooled SunTera energy storage system for an ESS project in China’s Qinghai Province to cover grid-scale applications including energy shifting.
SunTera G2 adopts an advanced intelligent liquid cooling system to regulate temperature, its flow channel design controlling the operating temperature difference of the energy storage system within 2.5 degrees Celsius, effectively improving its heat dissipation and ability to handle higher thermal loads while maintaining a low-temperature operation. The system adopts a cluster level management scheme to enable it to achieve higher efficiency and enhanced uniformity in cell-to-cell temperature improves charging and discharging capabilities, with round-trip efficiency (RTE) reaching up to 94% compared to the industry average of 92%, and a prolonged lifecycle of 8,000-10,000 cycles.
To facilitate the integration of local solar and wind power into the grid, Qinghai Province is aiming to develop an advanced renewable-plus-storage system to ensure a stable and reliable electricity grid.
