Order supports Energy Vault’s powered land and powered shell solutions for AI and data center customers, including hyperscalers

ST. AUGUSTINE, Fla., Sept. 23, 2026 /PRNewswire/ — 2G Energy AG has received a 275 MW order from Energy Vault Holdings Inc, (NYSE: NRGV) to supply power generation systems for Energy Vault’s powered land and powered shell AI energy infrastructure solutions in the United States. These solutions are designed to serve AI and data center customers, including hyperscalers. Based on current project planning, delivery of the systems is scheduled between the fourth quarter of 2027 and the third quarter of 2028.

Energy Vault is a publicly traded global 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. Its technology-agnostic platform combines on-site generation, battery energy storage, power conversion and VaultOS™ energy management software to accelerate time-to-power while maintaining the reliability and flexibility mission-critical operations require.

The project will utilize plug-and-play, containerized power generation systems based on 2G’s proven technology. The units will be pre-assembled and tested at 2G’s manufacturing facility in Heek, Germany, before shipping to the United States ready for on-site commissioning. The systems are designed to operate as the dispatchable generation layer within Energy Vault’s integrated power architecture, alongside battery energy storage and advanced controls. Together, these technologies will coordinate generation and storage in real time to support power quality, resilience and rapidly changing AI compute loads.

In addition to supplying and commissioning the systems, the order includes long-term service support. This will enable 2G to support the generation fleet throughout its lifecycle and help sustain the availability and operational performance required by mission-critical data center infrastructure.

“AI infrastructure customers need firm, always-on power on timelines that conventional grid interconnections often cannot meet. By integrating 2G’s modular generation systems with Energy Vault’s battery energy storage and VaultOS™ power plant controls, we can deliver a repeatable architecture that brings power online faster, responds in real time to dynamic AI workloads and can integrate grid power and renewables as they become available. 2G’s proven technology, manufacturing scale and lifecycle service capabilities make the company an important long-term partner as we expand this platform in the United States and internationally,” says Marco Terruzzin, Chief Revenue Officer of Energy Vault.

“This order demonstrates that our technology and our approach to standardized, high-performance, and rapidly deployable power generation solutions meet the requirements of the rapidly growing data center market,” says Pablo Hofelich, CEO of 2G Energy AG.

“For us, the focus extends beyond supplying the systems. Through long-term service, we also support their reliable operation throughout the entire lifecycle. The combination of high-performance power generation, a high degree of system integration, and consistently high availability is one of 2G’s proven strengths,” Hofelich adds.

Data Center Power Demand Continues to Grow
The global expansion of data centers is being driven by increasing digitalization, particularly the rapidly growing demand for computing capacity associated with artificial intelligence applications. For data center operators and developers, securing sufficient and reliable electrical power has become a critical infrastructure challenge.

On-site generation can complement existing grid infrastructure, particularly where grid capacity is constrained or additional power is required on accelerated timelines. For hyperscale AI campuses, pairing dispatchable generation with battery storage and intelligent controls can also support rapid load changes, power quality and high availability under demanding operating conditions, including high ambient temperatures.

For hyperscale projects, there is growing demand for integrated power architectures that can be standardized, manufactured at scale, transported efficiently and deployed in modular phases. 2G’s containerized systems support this approach through factory testing and rapid on-site integration.

“The data center market is developing very dynamically worldwide. Growing power demand, combined with limited grid capacity and constraints on available infrastructure and resources, is increasing the importance of alternative and decentralized power supply solutions,” says Hofelich. “We see this as a long-term growth market for 2G and are expanding our capabilities and production capacity accordingly.”

To meet growing demand and efficiently support projects of this scale, 2G is significantly expanding production capacity at its Heek facility. In addition to a new production hall that became operational earlier this year, a second production site is currently under development and is scheduled for completion by the end of 2027.
