2G Energy Secures 275 MW Order From Energy Vault to Power U.S. AI Data Centers German power generation specialist 2G Energy AG has received a 275-megawatt order from New York Stock Exchange-listed Energy Vault Holdings Inc to supply power generation systems for artificial intelligence infrastructure across the United States.

The equipment, scheduled for delivery between the fourth quarter of 2027 and the third quarter of 2028, will form the dispatchable generation layer within Energy Vault's integrated power architecture targeting data center customers and hyperscalers.

A Modular, Plug-and-Play Approach to On-Site Generation

The order centers on two Energy Vault product offerings described as "powered land" and "powered shell," both designed to address the power access challenges facing operators of large-scale AI computing campuses.

The generation systems supplied by 2G Energy will be built on a plug-and-play, containerized design, pre-assembled and tested at the company's manufacturing facility in Heek, Germany, before being shipped to the United States for on-site commissioning. Once deployed, the units will operate alongside battery energy storage systems and Energy Vault's VaultOS energy management software, forming what the company describes as a technology-agnostic integrated power platform.

The platform combines on-site generation, battery energy storage, power conversion and software controls, with the stated aim of shortening time-to-power while maintaining the reliability demanded by mission-critical operations.

Energy Vault has also indicated that the architecture is designed to eventually incorporate grid power and renewable energy sources as those become available at individual sites.

Beyond the initial equipment supply, the agreement includes a long-term service contract under which 2G Energy will support the generation fleet throughout its operational lifecycle, sustaining availability levels consistent with the demands of always-on infrastructure.

Executives Cite Speed and Reliability as Defining Requirements

Marco Terruzzin, Chief Revenue Officer of Energy Vault, stated that AI infrastructure customers require firm, always-on power on timelines that conventional grid interconnection processes frequently cannot accommodate.

He said that by integrating 2G's modular systems with battery energy storage and VaultOS plant controls, Energy Vault can deliver a repeatable architecture that brings power online faster and responds in real time to the dynamic load profiles generated by AI compute workloads. Terruzzin described 2G Energy as a long-term partner in expanding the platform both within the United States and internationally.

Pablo Hofelich, Chief Executive Officer of 2G Energy AG, said the order demonstrates that the company's standardized, high-performance and rapidly deployable generation solutions are aligned with the requirements of the fast-growing data center market. He emphasized that 2G's involvement extends beyond equipment supply, with the long-term service agreement designed to ensure reliable operation across the full lifecycle of the deployed systems.

Hofelich cited the combination of high-performance generation, strong system integration and consistently high availability as core and long-standing strengths of the company's offering.

Energy Vault's Platform and Market Position

Energy Vault describes itself as a publicly traded energy infrastructure company that develops, owns and operates integrated power solutions for utilities, independent power producers, industrial customers, and the AI and data center markets. The company's VaultOS software serves as the control layer for its power architecture, managing the interaction between on-site generation, battery storage and grid inputs to meet the operational demands of large computing facilities.

The company's platform is positioned specifically to address scenarios in which grid interconnection queues or constrained local transmission capacity prevent data center developers from securing power on the timelines their construction and commissioning schedules require. On-site generation, paired with battery storage and intelligent controls, is presented as a means of bridging that gap while also supporting power quality and load flexibility under demanding conditions, including high ambient temperatures typical of large-scale computing environments.

Data Center Demand Fueling Infrastructure Investment

The order reflects a broader acceleration in investment in power infrastructure tied to the global expansion of data centers.

The growth is being driven by increasing digitalization and, in particular, by the surge in demand for computing capacity linked to artificial intelligence applications. Securing sufficient and reliable electrical power has emerged as one of the most pressing infrastructure challenges for data center operators and developers, given the scale and speed at which new capacity is being brought online.

For hyperscale AI campuses, the pairing of dispatchable on-site generation with battery storage and intelligent control systems is increasingly seen as a means of managing rapid load changes, maintaining power quality, and sustaining high availability under the operating pressures that intensive AI workloads place on electrical infrastructure.

The context in which the deal was announced underscores the scale of activity in flexible energy infrastructure in the United States. The country installed a record 18.9 gigawatt-hours of storage capacity in the second quarter of this year, a figure that reflects the growing appetite for solutions capable of complementing or substituting for conventional grid supply.

2G Energy's Manufacturing and Service Capabilities

2G Energy AG, headquartered in Heek, Germany, will handle pre-assembly and testing of all containerized generation units at its German manufacturing facility prior to shipment to the United States.

The company's scope of work spans the full supply chain from production through commissioning and into long-term operational support under the service agreement included in the contract.

The 275-megawatt scale of the order positions it as a significant commercial milestone for the company in the North American market, and Hofelich's comments suggest the company views the engagement as a platform for further growth in the data center segment.
