EnergieTechnik Becker GmbH develops and manufactures high-quality container substations, medium voltage substations, and customized energy containers for industry, energy providers, data centers, and charging infrastructure. With POWERBOXX®, we offer tailored solutions for demanding energy infrastructure projects.

The POWERBOXX® container stations from EnergieTechnik Becker combine modern engineering with tested medium-voltage technology and maximum operational safety.
As a manufacturer, EnergieTechnik Becker develops individual container stations for demanding energy infrastructure projects. Each station is planned project-specifically and designed according to current standards.
From planning and engineering to commissioning, customers receive a well-conceived complete solution from a single source.

Container stations are a central component of modern energy infrastructures today. Whether it's an industrial plant, charging park, data center, or grid connection point – powerful medium-voltage solutions are used wherever electrical energy needs to be distributed safely.
EnergieTechnik Becker develops modern container stations for a wide range of applications with POWERBOXX®. Unlike standardized solutions, each station is created based on an individual engineering process, in which electrical, mechanical, and safety requirements are precisely coordinated.
This results in container stations that meet the highest demands for safety, operational reliability, and long-term availability.


An arc fault is one of the most critical fault events in medium-voltage systems. Extreme temperatures, pressure waves, and mechanical stresses occur within a very short time.
The POWERBOXX® was specially developed for these challenges. Through controlled pressure relief, defined pressure duct systems, and a robust container construction, people and systems are effectively protected.
The container station has been successfully tested for arc fault safety and meets the requirements of IEC 62271-200 and IEC 62271-202.

Answers to the most important questions regarding POWERBOXX® container stations, medium voltage technology, safety and areas of application.
A container station is a compact power supply system in which medium-voltage switchgear, transformers, and low-voltage distribution systems are integrated into a robust container housing. It enables safe and flexible power distribution for industrial plants, infrastructure projects, charging parks, and energy suppliers.
POWERBOXX® container substations are suitable for industrial plants, data centers, charging infrastructure, wind farms, photovoltaic systems, grid connection points, construction site power supply, and temporary grid replacement solutions, among other applications.
Yes. The POWERBOXX® container station has been successfully tested for arc fault safety and meets the requirements according to IEC 62271-200 and IEC 62271-202. The test confirms the classification IAC-AB 20 kA / 1 s.
This classification confirms that the container station can safely withstand an internal arc fault with a short-circuit current of 20 kA for a duration of one second, protecting persons inside and outside the station.
Yes. EnergieTechnik Becker develops the POWERBOXX® container stations entirely in-house. Each station is individually planned and adapted to the technical requirements of the respective project.
The design takes into account relevant medium-voltage standards, in particular IEC 62271-200 and IEC 62271-202. This ensures a standard-compliant and safe execution.
Yes. Each POWERBOXX® container station is developed specifically for the project. Switchgear, transformers, protection technology, room layout, ventilation systems, and safety concepts can be individually adapted to the project's requirements.
Yes. EnergieTechnik Becker realizes projects throughout Germany and supports clients from planning and engineering to the commissioning of the plant.
The POWERBOXX® container station combines modern engineering, tested safety, individual planning, and many years of experience in medium-voltage technology. Customers receive a tailor-made solution for a safe and reliable energy supply.
