Giant energy company, Energy Vault, Secures $300 Million Investment to Debut Expanded Energy Storage System
In a significant move for the renewable energy sector, Energy Vault, a leading provider of grid-scale energy storage solutions, has secured a $300 million preferred equity investment. This investment, from a leading multi-billion-dollar infrastructure fund, marks the launch of Asset Vault, a new subsidiary that will build, own, and operate energy storage assets.
The investment in Energy Vault's Asset Vault subsidiary is aimed at funding the deployment of 1.5 GW of energy storage projects, unlocking more than $1 billion in capital expenditures. The capital will also support attractive project financing to deliver the asset construction, commissioning, and operation.
The Stoney Creek Battery Energy Storage System (BESS) in New South Wales, Australia, has been acquired by Energy Vault and is now a part of the Asset Vault portfolio. With a capacity of 125 MW/1,000 MWh, the Stoney Creek BESS project is Energy Vault's first asset under the Asset Vault subsidiary.
The creation of Asset Vault unlocks the full potential of Energy Vault's 'Own and Operate' storage IPP strategy, which combines long-term contracted revenues with strategic capital and integrated, self-performed project execution. Energy Vault retains voting and operational control of Asset Vault and expects the platform to generate over $100 million in recurring annual EBITDA within 3–4 years.
The acquisition of the Stony Creek BESS project reinforces Energy Vault's expansion strategy in the Australian market. The new capital will be used for project development expenses, project acquisition, and equity investments. Asset Vault will consolidate Energy Vault's owned storage portfolio, including a 3 GW pipeline of battery energy storage systems (BESS) projects.
The $300 million investment in Energy Vault provides immediate investment flexibility for its 'Own and Operate' storage IPP strategy. Asset Vault will contract project design, construction, commissioning, and service agreements to Energy Vault. The additional revenue is expected to be additive to Energy Vault's existing Energy Storage Solutions business.
The acquisition of the Stony Creek BESS project follows Foreign Investment Review Board (FIRB) approval. Despite detailed reporting on the nature and goals of the investment, the specific name of the infrastructure fund that committed the preferred equity has not been publicly disclosed as of August 2025.
This investment marks a significant step forward in Energy Vault's mission to build a sustainable and resilient energy future. The funds will be used to scale resilience and meet the current needs driven by the penetration of renewable energy and the massive increases in energy demand driven by data center AI infrastructure.
