Energy Vault's Massive Battery Projects to Drive US Arbitrage by 2025
Energy Vault, a leading energy storage solutions provider, is making waves in the USA with its massive utility-scale battery projects. By 2025, the company will operate some of the largest installations, such as the 220 MW Reid Gardner BESS in Nevada and the 100 MW St. Gall BESS in Texas. These projects, designed to maximise battery energy density, are set to support energy arbitrage using advanced lithium-ion battery systems.
In 2024, a significant 66% of all utility-scale battery capacity in the US included arbitrage among its applications, with a substantial 41% primarily used for this purpose. Arbitrage, the practice of buying low and selling high, has emerged as the dominant use case for utility-scale battery energy storage systems in the country. Following arbitrage, frequency regulation is the next most common application, serving as the primary function for 24% of battery capacity.
Energy Vault's projects align with these trends, aiming to optimise energy use and stabilise the grid through strategic charging and discharging.
By 2025, Energy Vault's large-scale battery storage projects, such as the Reid Gardner and St. Gall BESS, will contribute to the growing use of arbitrage in the US energy storage landscape. These projects, along with others, will help maximise battery energy density and support the efficient management of energy resources.
