[Full-capacity Grid Connection of the World's First Large-scale Grid-side ESS Project Using In-situ Solidified Solid-state Batteries] On June 29, the world's first large-scale grid-side ESS project using in-situ solidified solid-state batteries achieved full-capacity grid connection. The overall construction scale of the project is 200MW/400MWh, with Phase I having completed 100MW/200MWh. The current phase of construction is 100MW/200MWh, adopting a prefabricated cabin layout and utilizing 280Ah semi-solid ESS batteries. This phase of the project installed a total of 44 battery prefabricated cabins, 22 PCS step-up integrated machines, and expanded one 220kV/35kV step-up substation.
