Modern energy supply is facing a massive transformation. Industrial companies require more electrical power, charging parks are growing, data centers are emerging, renewable energy systems must be reliably connected to the grid, and operators of technical infrastructure expect solutions that are safe, flexible, and available long-term. It is precisely in this environment that container substations are gaining increasing importance, because they combine medium-voltage technology, transformer technology, low-voltage distribution, protection technology, and mechanical container construction into a compact and project-specific configurable solution.
EnergieTechnik Becker GmbH develops its own container substations with POWERBOXX® for demanding energy infrastructure projects. EnergieTechnik Becker sees itself not only as a supplier of a ready-made station, but as a manufacturer and engineering partner for individual medium-voltage solutions that are designed for operational safety, personal protection, standard-compliant planning, and long-term technical availability.
What is a container substation?
A container substation is a compact electrical station in which central components of power distribution are integrated into a robust container housing. Depending on project requirements, this can include medium-voltage switchgear, transformers, low-voltage distribution systems, protection and measurement technology, ventilation systems, pressure relief concepts, and safety devices.
In contrast to traditional substation buildings, the technology is not housed in a permanently constructed building, but in a technically prepared container structure. This creates a flexible energy supply solution suitable for permanent installations as well as for temporary power supply, grid replacement solutions, construction site power supply, or rapid expansions of existing infrastructures.
Especially in the medium-voltage sector, however, a container substation is far more than a simple technical container. The electrical design, the mechanical construction, the thermal dimensioning, the protection technology, the accessibility for maintenance and operation, and the safe management of possible fault events must be precisely coordinated. This is precisely where the difference lies between a standard solution and a professionally developed container substation.
Why container substations are becoming increasingly important in energy technology
The energy demand of many companies and infrastructure projects is rising significantly. Production facilities are becoming more powerful, charging infrastructure requires high connection capacities, data centers demand high supply security, and renewable energy systems must be efficiently integrated into existing grids. At the same time, projects must be implemented more quickly, without compromising safety and technical quality.
Container substations offer several decisive advantages for these requirements. They can be planned project-specifically, constructed compactly, technically pre-equipped, and used flexibly. This often allows energy infrastructure projects to be realized faster than with purely structural substation solutions.
For operators, this means greater planning certainty, shorter realization times, and a solution that can be adapted to actual technical needs. This advantage is particularly relevant in medium-voltage technology, because not only is electrical power transmitted here, but there are also high demands on protection, safety, operation, and maintenance.
The POWERBOXX® from EnergieTechnik Becker
With POWERBOXX®, EnergieTechnik Becker is developing its own solution for container substations in the medium-voltage range. The focus is not on a standard series container, but on a technically sophisticated system solution that can be individually designed for each project.
The POWERBOXX® combines robust container construction with medium-voltage technology, transformer technology, low-voltage distribution, and safety concepts. Each substation is tailored to the requirements of the respective project. This includes, among other things, the electrical integration, the mechanical design, the thermal planning, the spatial layout, the ventilation, the pressure relief, and the accessibility for operation and maintenance.
EnergieTechnik Becker thus positions itself as a manufacturer of container substations that not only installs technology but develops complete energy infrastructure solutions.
Typical applications of container substations
Container substations are suitable for many applications where electrical energy needs to be safely distributed, transformed, or temporarily provided. They are particularly relevant for industrial plants, energy suppliers, grid operators, charging parks, data centers, photovoltaic systems, wind energy systems, construction sites, infrastructure projects, and temporary grid replacement solutions.
In industrial plants, container substations can be used when production capacities are expanded, new machines are installed, or existing energy distributions need to be modernized. For charging parks, they offer the possibility of centrally providing high electrical power and integrating medium-voltage technology compactly. Data centers benefit from a structured and secure power distribution, where availability and ease of maintenance are particularly important.
Container substations are also relevant for renewable energy systems, because generated energy must be reliably collected, transformed, and fed into the grid. For temporary projects, container substations can also be used as flexible grid replacement solutions when power is needed at short notice or existing systems need to be secured during maintenance or conversion.
Construction of a modern container substation
A professional container substation consists of several functional areas that are technically separated in a sensible way. There is often a switchgear room, which houses medium-voltage switchgear, protection technology, measurement technology, and low-voltage components. In addition, a transformer room can be provided, where the power transformer is installed.
This separation is important because different components have different requirements. Medium-voltage switchgear requires safe operability, clear accessibility, and standard-compliant protection concepts. Transformers generate heat and require appropriate ventilation. Protection and measurement technology must be positioned in such a way that operation, maintenance, and diagnosis are possible efficiently.
In the POWERBOXX®, this room structure is planned project-specifically. EnergieTechnik Becker takes into account not only the electrical function but also mechanical safety, pressure relief, thermal operation, and long-term maintainability of the system.
Arc fault safety as a key quality feature
A particularly important point for medium-voltage substations is safety in the event of a fault. An arc fault is one of the most critical events in electrical systems, as extreme temperatures, pressure waves, hot gases, and mechanical stresses can arise within a very short time. An uncontrolled fault can cause significant risks for operating personnel, maintenance personnel, and adjacent infrastructure.
Therefore, in modern container substations, not only the electrical function is crucial, but also a well-thought-out safety concept. The POWERBOXX® was developed precisely for these requirements. Central components include controlled pressure relief, defined pressure duct systems, targeted hot gas guidance, robust container construction, and safe separation of functional areas.
The POWERBOXX® has been successfully tested for arc fault safety and meets the requirements of IEC 62271-200 and IEC 62271-202. The confirmed classification IAC AB 20 kA for 1 second shows that the substation has been developed for high demands on personal and plant protection.
Why in-house development is crucial
Many container substations appear similar at first glance, but differ significantly technically. What matters is not only which components are installed, but how these components are integrated into an overall system. A medium-voltage switchgear, a transformer, and a container do not yet make a well-designed substation if pressure relief, ventilation, protection technology, accessibility, mechanical design, and operating concepts are not cleanly interconnected.
EnergieTechnik Becker therefore relies on its own engineering for the POWERBOXX®. Each substation is technically planned and designed project-specifically. This allows individual requirements to be taken into account, such as special connection capacities, spatial restrictions, safety requirements, climatic conditions, grid connection points, or project-specific specifications from operators and energy suppliers.
This in-house development is a central factor if EnergieTechnik Becker is to be perceived as a manufacturer of container substations. It is not about mere assembly, but about the development of a functional, safe, and long-term usable energy infrastructure solution.
Advantages of container substations over classic substation solutions
Container substations offer several advantages over traditional substation buildings. A key advantage is flexibility. A container substation can be adapted to different locations, performance requirements, and technical conditions. At the same time, it is compact and can often be implemented faster than a conventional structural solution.
Another advantage is predictability. When all relevant technical components are brought together in a well-designed unit, interfaces can be reduced and processes simplified. This is particularly important for projects that are under time pressure or where quick commissioning is required.
Container substations are also attractive for extensions of existing systems. If additional power is needed, a container substation can serve as a supplement to existing infrastructure. For temporary applications, it is also suitable because it can be used as a mobile or relocatable energy supply solution.
Container substations for charging parks and electromobility
A particularly growing application area is charging infrastructure. Modern charging parks require high electrical connection capacities, especially when several fast-charging points are to be operated simultaneously. In many cases, the existing low-voltage infrastructure is not sufficient for this. Then medium-voltage technology becomes necessary.
A POWERBOXX® container substation can be used here as a central energy supply unit. It integrates the necessary medium-voltage technology, transformer capacity, and distribution in a compact solution. This allows operators of charging parks to plan their infrastructure professionally and prepare for future expansions.
Especially in electromobility projects, it is important not to view the energy supply as a minor point. Without a safe and powerful medium-voltage infrastructure, charging parks cannot be operated reliably.
Container substations for industry and production
In industry, reliability and security of supply are particularly important. An unplanned power outage can interrupt production processes, shut down machines, and cause significant costs. Therefore, industrial companies need energy distribution systems that are reliable, maintainable, and technically future-proof.
Container substations can play a central role here. They enable power to be specifically provided where it is needed. At the same time, they can be adapted to the requirements of specific production areas, machine parks, or expansion projects.
With POWERBOXX®, EnergieTechnik Becker offers companies a solution that takes into account individual medium-voltage requirements and enables safe power distribution.
Container substations for data centers and critical infrastructure
Data centers and critical infrastructures place particularly high demands on energy supply. Availability, redundancy, security, and clear maintenance concepts are crucial here. A container substation can be used as part of a powerful energy infrastructure and contribute to providing electrical power safely and in a structured manner.
Especially for projects with high energy demand, early planning of medium-voltage technology is crucial. EnergieTechnik Becker supports operators in analyzing technical requirements, developing suitable substation concepts, and implementing standard-compliant solutions.
