California startup Energy Vault Holdings Inc. is nearing completion of its first major power-storage project, one of the only systems in the world to generate electricity using gravity.

The project in Rudong, China, north of Shanghai, will be finished by September, Chief Executive Officer Robert Piconi said Wednesday in an interview at Bloomberg’s New York headquarters. It will be able to deliver as much as 25 megawatts of power for four hours.
