Reid Gardner Battery Energy Storage System

Energy Vault’s custom-tailored Battery Energy Storage System (BESS) solution addresses NV Energy's unique project needs. The Reid Gardner short duration energy storage project improves Nevada's grid resilience and enable excess solar generation to serve demand after the sun sets.

Project Overview

Located on the site of a former coal-fired power plant 50 miles northeast of Las Vegas, the Reid Gardner Battery Energy Storage System (BESS) is a 220 MW / 440 MWh project.  
The Reid Gardner BESS is one of the largest of its kind in Nevada, providing bulk energy shifting for regionally produced renewable solar energy. The project also provides system-stabilizing ancillary services and bolster the state’s firm dispatchable generation capacity.  
Energy Vault collaborated with project owner and Nevada’s largest utility, NV Energy, to design a bespoke BESS solution and provide an Engineering, Procurement, and Construction (EPC) wrap on the project to ensure successful delivery and commissioning of the 440MWh asset in under 4 months.  
Energy Vault's custom BESS solution configuration is coordinated by its technology-agnostic VaultOS energy management software. As part of the full lifetime maintenance of the project, Energy Vault is also providing a Long-Term Service Agreement (LTSA).
