2G Energy Books 275 MW Order for Energy Vault AI Data Center Power

2G Energy AG has received a 275 MW order from Energy Vault Holdings for power generation systems supporting Energy Vault’s powered land and powered shell AI energy infrastructure solutions in the United States, according to a company press release dated September 23, 2026. Under current project planning, delivery of the systems is scheduled between the fourth quarter of 2027 and the third quarter of 2028.

Order Terms and Heek Manufacturing

The solutions are designed to serve AI and data center customers, including hyperscalers. In an issuer disclosure published the same day, 2G described the contract as another order for energy infrastructure solutions for AI data centers in the United States totaling 275 MW. 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 project will use plug-and-play, containerized power generation systems based on 2G’s technology. Beyond supplying and commissioning the systems, the order includes long-term service support, enabling 2G to support the generation fleet throughout its lifecycle and help sustain the availability and operational performance required by mission-critical data center infrastructure.

Dispatchable Generation Alongside Battery Storage

According to the release, 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, coordinating generation and storage in real time to support power quality, resilience, and rapidly changing AI compute loads. The release describes Energy Vault’s technology-agnostic platform as combining on-site generation, battery energy storage, power conversion, and VaultOS energy management software.

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 portfolio spans short-, long-, and multi-day duration storage, and it operates under a Build, Own & Operate model.

Executive Statements

“AI infrastructure customers need firm, always-on power on timelines that conventional grid interconnections often cannot meet,” said Marco Terruzzin, Chief Revenue Officer of Energy Vault. He said that integrating 2G’s modular generation systems with Energy Vault’s battery storage and VaultOS power plant controls delivers 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. Terruzzin said 2G’s technology, manufacturing scale, and lifecycle service capabilities make the company an important long-term partner as Energy Vault expands the platform in the United States and internationally.

Pablo Hofelich, CEO of 2G Energy, said the order demonstrates that the company’s technology and its approach to standardized, high-performance, and rapidly deployable power generation meet the requirements of the rapidly growing data center market. “For us, the focus extends beyond supplying the systems. Through long-term service, we also support their reliable operation throughout the entire lifecycle,” Hofelich said, describing the combination of high-performance power generation, a high degree of system integration, and consistently high availability as one of 2G’s proven strengths.

Demand Context and Heek Capacity Expansion

The release states that global data center expansion is being driven by increasing digitalization, particularly growing demand for computing capacity associated with artificial intelligence applications, and that securing sufficient and reliable electrical power has become a critical infrastructure challenge for operators and developers. On-site generation can complement existing grid infrastructure, particularly where grid capacity is constrained or additional power is required on accelerated timelines, and pairing dispatchable generation with battery storage and intelligent controls can support rapid load changes, power quality, and high availability under demanding operating conditions, including high ambient temperatures. For hyperscale projects, the release adds, there is growing demand for integrated power architectures that can be standardized, manufactured at scale, transported efficiently, and deployed in modular phases.

Hofelich said 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, which he described as a long-term growth market for 2G. To meet growing demand and support projects of this scale, 2G is expanding production capacity at its Heek facility: a new production hall became operational earlier in 2026, and a second production site is under development with completion scheduled by the end of 2027.

2G Energy’s Portfolio and Corporate Profile

2G Energy develops, manufactures, and installs decentralized energy supply solutions spanning combined heat and power systems, large-scale heat pumps, and peaking power generation systems. Its portfolio includes combined heat and power systems with electrical outputs from 20 kW to 4,500 kW designed to run on hydrogen, natural gas, biogas, and other low-calorific gases; large-scale heat pumps with thermal outputs from 68 kW to 3,200 kW; and peaking power generation systems starting at 500 kW of electrical output. The company states that its combined heat and power systems can achieve overall efficiencies of 90 percent and higher, that its large-scale heat pumps can reach a coefficient of performance of up to 5 depending on operating conditions, and that more than 10,000 2G systems are installed worldwide.

According to the issuer disclosure, 2G employs more than 1,000 people, is active in more than 60 countries, and generated net sales of EUR 398 million in the 2025 financial year with an EBIT margin of 6.6 percent. The company was founded in 1995 and has been listed since 2007 in the Frankfurt Stock Exchange’s Scale segment and the Scale30 index. The disclosure’s financial calendar lists publication of 2G’s preliminary first-half 2026 results for September 29, 2026, and the company’s first Capital Markets Day in Heek for October 1, 2026.
