Energy Vault has taken a major step in expanding its renewable energy storage footprint with a substantial capital infusion aimed at scaling its Independent Power Producer (IPP) strategy. The investment will enable the company to accelerate large-scale projects worldwide while strengthening its ability to own and operate critical energy infrastructure.

Energy Vault, a global leader in grid-scale energy storage, has secured a USD 300 million exclusive preferred equity investment from a major infrastructure fund to launch Asset Vault, a new fully consolidated subsidiary. This funding will be used for project development costs, acquisitions, and equity investments to support the construction, commissioning, and operation of energy storage assets—both standalone and paired with generation—in key markets across the U.S., Europe, and Australia.

The creation of Asset Vault is designed to accelerate the execution of approximately 1.5 gigawatts of energy storage projects, unlocking over USD 1 billion in capital expenditures and positioning the platform to generate over USD 100 million in recurring annual EBITDA within the next 3–4 years.

“The USD 300 million investment and the creation of Asset Vault unlock the full potential of our ‘Own and Operate’ storage IPP strategy with immediate investment flexibility. By combining long-term contracted revenues with strategic capital and integrated, self-performed project execution, we are well-positioned to scale resilient, mission-critical energy infrastructure to meet the current needs driven by the penetration of renewable energy and the massive increases in energy demand driven by data center AI infrastructure,” said Energy Vault's Chairman & CEO, Robert Piconi.

Energy Vault was ranked at the TOP 100 Swiss Startup Award in 2022.
