Energy Vault and Astor Enerji have signed an agreement to deploy battery energy storage system (BESS) solutions for projects in Romania and for the provision of transformer and high-voltage tech for projects in the US, Australia and Europe.
Under the agreement, Energy Vault will supply B-VAULT BESS solutions for Astor Enerji’s four grid-connected PV projects in Romania, delivering a combined storage capacity of up to 2GWh. These systems will be integrated with Energy Vault’s VaultOS energy management system platform for optimal performance and grid stability.
Energy Vault will source over 1GW of transformers and high-voltage equipment from Astor to support its BESS projects, which are being developed and operated through Asset Vault — a fully owned subsidiary dedicated to building, owning, and operating energy storage assets.
On the side of Astor Enerji, the Turkey-based global manufacturer will provide transformers and high-voltage equipment for more than 1GW of Energy Vault BESS projects planned in the US, Australia, and Europe.
The agreement combines Energy Vault’s portfolio of advanced long- and short-duration energy storage hardware solutions and AI-driven software platform with Astor Enerji’s manufacturing scale and global delivery track record.

Commenting in a release was Olcay Doğan, chief financial officer of Astor Enerji: “Energy Vault’s innovative approach to energy storage, combined with their extensive global project pipeline, makes them an ideal partner as we expand our footprint in the rapidly growing battery storage sector.
“This agreement builds on our mission to deliver the grid infrastructure needed for a sustainable energy future, and we are excited to create lasting commercial and technological value together.”
Said Marco Terruzzin, chief revenue officer, Energy Vault: “This partnership is about more than equipment supply — it’s about aligning two high-growth companies to solve the most pressing challenges in the energy transition.
“Together, we are building the technology and supply chain capacity to meet surging power demand from AI data centres and the rapid adoption of renewable energy. This is how we deliver power abundance and economic growth on a global scale.”
The partnership comes at a tight time for the US transformer supply chain, with wait times stretching from 50 weeks to as long as 127 weeks, says Energy Vault. This collaboration addresses such supply shortages by leveraging Astor Enerji’s manufacturing capacity and global supply chain to ensure access to high-quality equipment.
Research released by Wood Mackenzie last week detailed the weak supply chain, describing how surging demand has plunged transformer markets into a significant deficit with supply unable to keep up with the burgeoning demand.
The company estimates that power transformers and distribution transformers are currently in a supply deficit of 30% and 6%, respectively for the country, based on annual supply and demand estimates.
