Hitachi Energy to Supply 110kV Grid Connection for Kauri CAB Data Center in Frankfurt

Hitachi Energy has secured a contract to deliver a dedicated 110kV grid connection for a data center being developed by Kauri CAB Digital Infrastructure in Frankfurt, Germany. The solution is specifically designed to meet the challenges of integrating high-density power infrastructure into a constrained urban environment. As the data center industry faces growing pressure to secure reliable electricity supply in densely populated areas, this project highlights the increasing importance of compact and resilient grid interconnection technologies.

The grid connection, which Hitachi Energy claims offers high reliability within a compact footprint, is intended to reinforce the interface between transmission and distribution networks. This reinforcement is expected to support stable accommodation of Frankfurt’s rising electricity demand, driven in part by the expansion of digital infrastructure. No specific timeline for deploying the connection has been disclosed.

“Power systems are evolving faster than at any point in recent history, shifting from stable, centrally planned networks to highly dynamic systems that must integrate concentrated new demand, variable power flows, and rising resilience requirements,” said Marco Berardi, head of grid and power quality solutions and service at Hitachi Energy. “By delivering compact and advanced grid connections, we help customers such as Kauri CAB move forward with confidence, while strengthening the resilience of the broader electricity system and further reinforcing our strong position in the data center market.”

Although Hitachi Energy has not confirmed the exact location, the grid connection is widely expected to serve a data center project on a 55,000-square-meter land parcel in Hochheim, which Kauri acquired in April for €24 million. According to reports at the time of the acquisition, the planned facility is expected to deliver approximately 40MW of capacity upon completion. Kauri, a Berlin-based real estate specialist, is known for residential developments such as Wasserstadt Mitte and Berlin Spandau.

The deal is the latest in a series of power infrastructure announcements from Hitachi Energy. In April, the company partnered with Samsung Engineering & Construction Group to develop high-voltage alternating current grid infrastructure aimed at meeting data center demand. It has also signed agreements with OpenAI to supply power transmission and distribution equipment for the AI firm’s data centers, and with regional transmission operator Southwest Power Pool to develop an Nvidia-powered AI solution that shortens interconnection impact study timelines. These moves underscore Hitachi Energy’s growing footprint in the data center power solutions market, where grid congestion and interconnection delays have become critical bottlenecks for new development.
