Energy Vault: $50 Million Secured For Grid-Scale Storage Solutions

By Amit Chowdhry ● Sep 29, 2025

Energy Vault Holdings, a leader in developing sustainable grid-scale energy storage solutions, has recently announced a significant step to bolster its financial position and support its ambitious growth plans. The company has entered into a definitive funding agreement with YA II PN, Ltd., securing up to $50 million in corporate debenture financing.

This agreement provides Energy Vault with enhanced financial flexibility at the holding company level, which is crucial for the continued expansion of its energy storage project development and execution. This funding will enable Energy Vault to accelerate its efforts in bringing more innovative and sustainable energy solutions to market.

This recent funding agreement is entirely separate from and in addition to a previously announced $300 million preferred equity investment. This larger investment, which involves a leading infrastructure investor, is currently pending its final closure. Once this significant transaction is complete, Asset Vault will be established as a fully consolidated subsidiary of Energy Vault. This new entity will be dedicated to housing and managing Energy Vault’s growing portfolio of energy storage assets that the company will both own and operate.

Long-term offtake agreements will strategically support these valuable assets. These agreements are designed to guarantee project monetization and will serve as a strong foundation for Energy Vault’s independent power producer (IPP) strategy. This approach is expected to generate reliable and recurring revenue streams for the company, characterized by high margins and securely contracted cash flows.

Energy Vault’s expanding portfolio of owned and operated energy storage projects is already quite impressive and continues to grow. This portfolio currently includes operational facilities located in Texas and California, which are actively contributing to grid stability and renewable energy integration. Furthermore, the company recently acquired the substantial 1 GWh Stoney Creek project in Australia, significantly extending its international reach and capacity.

Energy Vault also boasts a robust development pipeline, encompassing approximately 3 gigawatts of battery energy storage systems spread across various key markets, including the United States, Europe, and Australia. This demonstrates Energy Vault’s commitment to becoming a global leader in providing essential energy storage solutions for a more sustainable future.

KEY QUOTE:

“This new facility provides Energy Vault with the working capital resources to continue scaling our business and delivering on our growth projects without constraint. Importantly, this cash is in addition to the preferred equity we previously announced in support of owning and operating energy assets, ensuring incremental liquidity for Energy Vault Holdings as we expand our third-party project pipeline.”
