About Energy Vault
Energy Vault is an energy infrastructure company founded in 2017 that supplies grid operators and large consumers with utility-scale energy storage, backup power and powered infrastructure for AI and data centers. The company operates an integrated build-own-operate model: projects are developed, financed, built, commissioned and operated over the long term – from BESS to solar+storage and hydrogen integration to gas engine power plants (RICE). At the core of the platform is a technology-agnostic, software-based architecture with proprietary energy management and power plant control technology. Customers include NV Energy, Wellhead Electric, Kore Power, Cemex, China Tianying (Atlas Renewable) and Crusoe. The portfolio comprises more than 1 GW of power and energy assets under management as well as a pipeline of over 5 GWh across six major electricity markets from North America to Australia. Energy Vault Holdings, Inc. has been listed on the NYSE (NRGV) since 2022.
