2G Energy AG has received a 275-megawatt order from New York Stock Exchange-listed Energy Vault Holdings, Inc. to supply containerized power generation systems for AI and data center customers across the United States.

The order represents a significant commercial milestone for 2G Energy as demand for reliable, on-site power generation at hyperscale computing facilities continues to accelerate.

Scope and Timeline of the Agreement

Under the terms of the order, 2G Energy will supply plug-and-play, containerized power generation systems that will form the dispatchable generation layer within Energy Vault's integrated power architecture.

The systems are designed to operate alongside battery energy storage and advanced control technologies, coordinating generation and storage in real time to support power quality, resilience, and the rapidly changing load profiles characteristic of AI compute workloads.

Delivery of the systems is scheduled to take place between the fourth quarter of 2027 and the third quarter of 2028, based on current project planning. In addition to the supply and commissioning of the equipment, the agreement includes long-term service support, enabling 2G Energy to support the generation fleet across its full operational lifecycle.

The systems will be pre-assembled and tested at 2G Energy's manufacturing facility in Heek, Germany, before being shipped to the United States ready for on-site commissioning.

This factory-testing approach is designed to reduce deployment timelines and simplify integration once the units arrive at their destination sites.

Energy Vault's Platform and Customer Base

Energy Vault describes itself as a technology-agnostic 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 platform combines on-site generation, battery energy storage, and power conversion and its proprietary VaultOS energy management software, which the company says is designed to accelerate time-to-power while maintaining the reliability and flexibility that mission-critical operations require.

The 275 MW order specifically supports Energy Vault's powered land and powered shell solutions, which are aimed at AI and data center customers, including hyperscalers.

Marco Terruzzin, Chief Revenue Officer of Energy Vault, said that AI infrastructure customers need firm, always-on power on timelines that conventional grid interconnections often cannot meet.

Terruzzin described 2G's modular generation systems as part of a repeatable architecture capable of bringing power online faster and responding in real time to dynamic AI workloads, with the ability to integrate grid power and renewables as they become available.

2G Energy's Manufacturing Expansion

To meet the growing scale of orders such as the one announced with Energy Vault, 2G Energy is significantly expanding production capacity at its Heek facility in Germany.

A new production hall became operational earlier in 2026, and a second production site is currently under development, with completion scheduled by the end of 2027.

Pablo Hofelich, Chief Executive Officer of 2G Energy AG, said the order demonstrates that the company's standardized, high-performance, and rapidly deployable power generation solutions meet the requirements of the data center market.

Hofelich emphasized that the company's focus extends beyond supplying the hardware, noting that long-term service support and consistently high availability represent core strengths of 2G's offering.

He also described the data center sector as a long-term growth market for the company, citing growing power demand, limited grid capacity, and constraints on available infrastructure as factors driving demand for decentralized power supply solutions.

Broader Market Context

The order reflects wider pressures facing the data center industry as operators and developers scramble to secure sufficient and reliable electrical power.

The global expansion of data centers has been driven by increasing digitalization and the rapidly growing computing demands associated with artificial intelligence applications.

For hyperscale AI campuses in particular, grid capacity constraints and extended interconnection timelines have elevated the strategic importance of on-site generation.

The companies note that pairing dispatchable generation with battery storage and intelligent controls can address rapid load changes, support power quality, and maintain high availability under demanding operating conditions, including high ambient temperatures.

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