Energy Vault Holdings, Inc. (NYSE: NRGV) (“Energy Vault” or the “Company”), a leader in sustainable grid-scale energy storage solutions, announced today that NV Energy, Nevada’s largest public utility, has awarded the Company with a project for the deployment of a short duration energy storage solution. The Battery Energy Storage System (BESS), one of the largest in Nevada, is expected to start construction in Q2 2023 with commercial operation expected by the end of 2023.

The 220MW/440MWh grid-tied BESS will be deployed at a site located near Las Vegas. The 2-hour energy storage system is designed to store and dispatch excess renewable energy, including wind and solar power.
