Energy Vault has announced a global strategic agreement with Astor Enerji for a coordinated supply of energy storage systems, transformers, and high-voltage equipment. The partnership aims to accelerate deployment and strengthen global supply chains for battery energy storage systems (BESS) in critical infrastructure projects, including artificial intelligence (AI) data centers, grid-connected photovoltaic (PV) facilities, and utility-scale energy storage. This agreement responds to extended transformer wait times, with US transformer lead times reportedly reaching as long as 127 weeks, by prioritizing external supply chain sources.
Under the agreement, Energy Vault will deliver up to 2 gigawatt-hours (GWh) of its B-VAULT energy storage systems to Astor Enerji’s four grid-connected PV projects in Romania. These BESS installations will use Energy Vault’s VaultOS energy management platform, designed to optimize storage dispatch and grid performance. In return, Astor Enerji will supply more than 1 gigawatt (GW) of power transformers and high-voltage equipment for Energy Vault’s global BESS projects, covering deployments in the United States, Australia, and Europe.
Energy Vault states that the integration of its advanced hardware portfolio and VaultOS software with Astor Enerji’s manufacturing scale establishes a more resilient supply chain and infrastructure platform for high-growth markets, such as data centers and renewable power installations. Sourcing for the BESS projects will occur under Asset Vault, Energy Vault’s subsidiary dedicated to building, owning, and operating energy storage assets. Asset Vault is backed by a $300 million preferred equity investment to support its independent power producer strategy.
Marco Terruzzin, Chief Revenue Officer at Energy Vault, said, “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,” and continued, “Together, we are building the technology and supply chain capacity to meet surging power demand from AI data centers and the rapid adoption of renewable energy. This is how we deliver power abundance and economic growth on a global scale.”
Olcay Doğan, Chief Financial Officer at Astor Enerji, stated, “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,” and added, “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.”
