2G Energy Energy Vault received a 275 MW order from Energy Vault Holdings Inc. to supply power generation systems for artificial intelligence projects and data centers in the United States, the agreement includes equipment that will be part of the energy solutions developed by Energy Vault for AI customers, data centers, and hyperscale cloud service providers. According to the current plan, deliveries will take place between the fourth quarter of 2027 and the third quarter of 2028. The contract also includes long-term technical support to assist with the operation of the equipment throughout its lifecycle.
2G Energy will supply power generation for AI data centers
Specifically, 2G Energy will supply modular generation systems designed to integrate into Energy Vault’s energy architecture. The units will be pre-assembled and tested at 2G’s facility in Heek, Germany, and then shipped to the United States for installation and commissioning at their respective sites.
This modular manufacturing model reduces some of the on-site integration work and facilitates the progressive development of large-scale installations. Within the Energy Vault infrastructure, the equipment will function as a manageable generation source. The architecture will also incorporate energy storage via batteries and advanced control systems. This combination aims to coordinate generation and storage in real time to respond to load variations inherent in computing operations linked to artificial intelligence.
Energy Vault will integrate generation, batteries and VaultOS
Energy Vault develops integrated energy infrastructure for electric utilities, independent power producers, industrial customers, and operators related to the artificial intelligence and data center markets, its platform combines on-site generation, battery storage, power conversion systems, and energy management software VaultOS.
Integrating these resources allows for the coordination of electricity production and storage to maintain supply quality and respond to rapid changes in demand. Marco Terruzzin, Revenue Director at Energy Vault, explained that customers with AI infrastructure need firm energy availability within timeframes that conventional grid interconnections cannot always meet.
The combination of 2G Energy’s systems with batteries and VaultOS is designed as an architecture that can be replicated in different projects, in addition, it will be able to incorporate electricity from the grid and renewable sources as they become available.
The order includes long-term technical support
In addition to the supply and commissioning of the equipment, 2G Energy it will offer long-term technical support for the generation fleet; the service will be geared towards maintaining the availability and operational performance required by a critical infrastructure such as data centers.
Pablo Hofelich, CEO of 2G Energy AG, noted that the order demonstrates the ability of the company’s standardized systems to meet the needs of the data center market. He also emphasized the importance of providing service throughout the equipment’s entire lifecycle.
The company offers cogeneration systems, large-scale heat pumps, and generation solutions designed to meet peak demand. Its cogeneration portfolio includes electrical capacities ranging from 20 kW to 4,500 kW and can operate using hydrogen, natural gas, biogas, and other low-calorific-value gases.
Artificial intelligence increases the demand for electricity
Meanwhile, the expansion of data centers is increasing the electrical capacity needs related to digitization and application development artificial intelligence this growth makes the availability of a stable supply an increasingly important factor for developers and operators of large technology campuses.
In this context, on-site generation emerges as an alternative to complement the grid in areas where there is little available capacity or when projects need to incorporate new power in shorter timeframes. In hyperscale AI data centers, combining manageable generation, batteries and control systems also helps to respond to rapid variations in load and maintain high levels of availability.
Large-scale projects also require architectures that can be mass-produced and deployed gradually, 2G Energy’s containerized systems meet this model through pre-factory testing followed by on-site integration.
2G Energy expands its production in Germany
In response to growing demand, 2G Energy is expanding its manufacturing capacity in Heek, the company commissioned a new production facility in early 2026 and has another production facility currently under construction.
For 2G Energy, the increase in electricity consumption associated with the data centers and the capacity constraints facing some grids are creating new opportunities for decentralized generation solutions. Energy Vault’s 275 MW order incorporates these systems into an architecture that will combine power generation, battery storage, and digital management to power artificial intelligence infrastructure in the United States.
