Energy Vault Holdings, Inc. and NV Energy announced the completion and beginning of commercial operation of the Reid Gardner Battery Energy Storage System (BESS) in Moapa, Nevada. Built on the site of a decommissioned coal-fired electric generating facility, the 220MW/440MWh grid-tied BESS, is a 2-hour energy storage system that is designed to store and dispatch excess renewable energy, including wind and solar power. The BESS is charged and discharged on a daily basis and designed to dispatch stored renewable energy at peak consumption hours to help meet the high demand during Nevada?s peak load hours.

The system, which is now being operated at full capacity by NV Energy, leverages Energy Vault?s integration platform and energy management system (Vault-OS).
