Power systems manufacturer 2G Energy booked a 275 MW order for Energy Vault's thermal storage and power delivery systems supporting AI data center operations.
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. Delivery of the systems is scheduled between the fourth quarter of 2027 and the third quarter of 2028.
The units will be pre-assembled and tested at 2G's manufacturing facility in Heek, Germany, before shipping to the United States for on-site commissioning. These plug-and-play, containerized power generation systems are designed to serve AI and data center customers, including hyperscalers. Beyond system supply and commissioning, the order includes long-term service support to sustain availability and operational performance throughout the fleet's lifecycle.
The systems are designed to operate as the dispatchable generation layer within Energy Vault's integrated power architecture, coordinating on-site generation with battery energy storage and advanced controls in real time. This architecture supports power quality, resilience, and rapidly changing AI compute loads while integrating grid power and renewables as available. Energy Vault's technology-agnostic platform combines on-site generation, battery energy storage, power conversion, and VaultOS energy management software. The publicly traded company develops, owns, and operates integrated power solutions for utilities, independent power producers, industrial customers, and the AI and data center markets, operating under a Build, Own & Operate model.
"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 noted that integrating 2G's modular generation systems with Energy Vault's battery storage and VaultOS controls delivers a repeatable architecture that brings power online faster, responds in real time to dynamic workloads, and can coordinate grid and renewable power. "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," Terruzzin said.
Pablo Hofelich, CEO of 2G Energy, said the order demonstrates that the company's standardized, high-performance, rapidly deployable power generation meets data center market requirements. "For us, the focus extends beyond supplying the systems. Through long-term service, we also support their reliable operation throughout the entire lifecycle," he said, describing high-performance generation, system integration, and consistently high availability as proven strengths.
Global data center expansion, driven by digitalization and growing AI computing demand, has made securing reliable electrical power a critical infrastructure challenge. On-site generation complements existing grid infrastructure where grid capacity is constrained or power is needed on accelerated timelines. Pairing dispatchable generation with battery storage and intelligent controls supports rapid load changes, power quality, and high availability under demanding operating conditions, including high ambient temperatures. For hyperscale projects, integrated power architectures that are standardized, manufactured at scale, and deployed in modular phases command growing demand.
Hofelich characterized growing power demand, limited grid capacity, and infrastructure constraints as drivers of a long-term growth market in alternative and decentralized power supply solutions. To meet this demand, 2G is expanding production capacity at Heek: 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 develops, manufactures, and installs decentralized energy solutions spanning combined heat and power systems, large-scale heat pumps, and peaking power generation. Its combined heat and power systems deliver electrical outputs from 20 kW to 4,500 kW on hydrogen, natural gas, biogas, and other low-calorific gases; large-scale heat pumps provide thermal outputs from 68 kW to 3,200 kW; and peaking power generation systems start at 500 kW of electrical output. The company reports achieving overall efficiencies of 90 percent and higher in combined heat and power systems, coefficient of performance up to 5 in large-scale heat pumps depending on operating conditions, and more than 10,000 systems installed worldwide.
The company employs more than 1,000 people, operates in more than 60 countries, and generated net sales of EUR 398 million in 2025 with an EBIT margin of 6.6 percent. Founded in 1995 and listed since 2007 on the Frankfurt Stock Exchange's Scale segment and Scale30 index, 2G will publish preliminary first-half 2026 results on September 29, 2026, and will host its first Capital Markets Day in Heek on October 1, 2026.
