Located outside of Shanghai in Rudong, Jiangsu Province, China, the 25MW/100MWh EVx GESS is built adjacent to a wind farm and a national grid interconnection site in the hopes of balancing the country’s national energy grid through long duration storage of renewable energy.
Commissioning began in June on the power electronics and what the company calls “new ultra-efficient ‘ribbon’ lifting systems”, they stated in a press release announcing the commissioning.
The system is expected to be fully grid interconnected in Q4 2023 as planned with local state grid authorities, which Energy Vault states will make EVx the world’s first commercial, utility scale non-pumped hydro GESS.
According to Energy Vault, the EVx system is expected to have round trip efficiency (RTE) above 80%.
