China connects gravity storage and launches three new projects

Energy Vault | 6 March 2024

Swiss-based storage developer Energy Vault has confirmed China state grid interconnection and inverse power operation for the Rudong EVx system announced in 2023, alongside construction on three additional grid-scale EVx gravity energy storage system (GESS) deployments in the country.

Following the start of grid interconnection in September 2023, the 25MW/100MWh EVx GESS in Rudong achieved full interconnection after the completion of the final 4km 35kV overhead power line to a remote end substation, as planned with local state grid authorities.

Upon final provincial and state approvals for the start of commercial operation to the state grid, the Rudong EVx will be the world’s first commercial, utility-scale non-pumped hydro gravity energy storage system.
