When companies, energy suppliers, grid operators, or operators of critical infrastructure are faced with the task of installing new medium-voltage technology, a fundamental question often arises: should the power supply be implemented in a container station or in a classic building station?
Both solutions are legitimate and have been successfully used for many years. Nevertheless, the requirements for modern energy infrastructure are continuously changing. Projects need to be implemented faster, energy demands are increasing, locations are becoming more complex, and at the same time, demands for safety, availability, and cost-efficiency are growing.
Precisely for this reason, more and more companies are opting for modern container stations. They offer high flexibility, short realization times, and enable efficient integration of modern medium-voltage technology.
EnergieTechnik Becker GmbH is developing the POWERBOXX® container station, a solution specifically designed for the requirements of modern energy infrastructure. But when is a container station the better choice, and when can a building station be useful?
The Role of Medium-Voltage Stations in Modern Energy Projects
Regardless of their design, medium-voltage stations have a central task. They manage the safe distribution of electrical energy between the grid connection, transformer, medium-voltage switchgear, and low-voltage level.
Whether it's an industrial plant, charging park, data center, wind farm, or infrastructure project – a reliable power supply would not be possible without powerful medium-voltage stations.
Modern stations must do far more than they used to. In addition to pure power distribution, issues such as operational safety, arc fault protection, ease of maintenance, digitalization, remote monitoring, and future expandability play an increasingly important role today.
What is a Building Station?
A building station is a permanently installed technical facility housed within a specially planned building or technical room.
First, the building structure is erected. Subsequently, the electrical components are integrated, such as:
- Medium-voltage switchgear
- Transformers
- Low-voltage distribution
- Protection technology
- Measurement technology
- Communication systems
Building stations are often used where large technical facilities are planned for the long term or where existing buildings can be utilized.
Planning is carried out in close coordination between construction planning, electrical engineering, fire protection, and infrastructure planning.
What is a Container Station?
A container station takes a different approach. Here, all relevant technical components are already integrated within a specially designed container structure.
The station is planned and delivered as a complete energy system.
Depending on the project, the following components can be integrated:
- Medium-voltage switchgear
- Power transformers
- Low-voltage distribution systems
- Protection technology
- Measurement technology
- Remote control technology
- Ventilation systems
- Pressure relief systems
The POWERBOXX® from EnergieTechnik Becker is an example of a modern container station where all technical and safety-relevant requirements are already considered in the engineering phase.
Why Container Stations Are Being Used More and More Frequently
The energy industry is undergoing a fundamental transformation. New industrial projects, electromobility, battery storage, data centers, and renewable energies mean that power supply must now be planned with significantly more flexibility than just a few years ago.
At the same time, many projects are under considerable time pressure.
Here, container stations offer a decisive advantage.
Since technical integration already takes place during manufacturing, numerous work steps can be carried out in parallel. While foundation work is underway on the construction site, the station can already be produced and equipped.
This often significantly shortens project durations.
Cost-Efficiency in Direct Comparison
Cost-efficiency plays a central role in investment decisions.
At first glance, a classic building station often appears to be a familiar solution. However, when all project costs are considered, a different picture often emerges.
With a building station, additional costs arise for:
- Construction planning
- Permits
- Shell construction
- Finishing trades
- Fire protection measures
- Technical building equipment
- Longer construction times
With a container station, many of these points are eliminated or significantly reduced.
Since large parts of the system are pre-fabricated at the factory, the effort on the construction site is significantly reduced.
Especially for time-critical projects, this can represent a decisive economic advantage.
Flexibility as a Decisive Future Factor
Another advantage of modern container stations lies in their flexibility.
Many companies today do not know exactly how their energy demands will develop in the coming years.
New production lines, additional charging infrastructure, or increasing power requirements can lead to existing power supply systems needing to be expanded.
Container stations enable significantly greater adaptability here.
They can be:
- expanded
- supplemented
- relocated
- used temporarily
- serve as a backup power solution
This flexibility is a great advantage, especially in dynamic infrastructure projects.
Safety as a Key Decision Criterion
In medium-voltage systems, safety must never be a secondary issue.
Regardless of whether a station is installed in a building or in a container, the highest demands on personnel and plant protection must be met.
The decisive factor here is not the design, but the quality of the safety concept.
Modern container stations like the POWERBOXX® feature comprehensive safety solutions specifically tailored to the requirements of medium-voltage technology.
These include:
- controlled pressure relief
- arc fault protection
- pressure duct systems
- hot gas routing
- robust construction
- secure room separation
This allows even critical fault events to be controlled.
Arc Fault Safety as a Quality Feature
A significant difference between simple standard stations and professionally developed solutions lies in the control of arc fault events.
An arc fault can generate enormous temperatures, pressure waves, and mechanical stresses in a very short time.
Therefore, EnergieTechnik Becker develops the POWERBOXX® with an integrated safety concept specifically designed for the requirements of modern medium-voltage infrastructure.
The successfully passed tests according to IEC 62271-200 and IEC 62271-202 confirm the high safety quality of the station.
Maintenance Friendliness and Operation
In addition to safety, ease of maintenance plays a crucial role.
Technical systems must be able to operate reliably for many years.
Container stations offer numerous advantages here.
Thanks to the structured room layout, maintenance work can be carried out efficiently.
At the same time, technical components are easily accessible and can be replaced if necessary.
The POWERBOXX® has clearly separated functional areas for:
- medium voltage
- transformer technology
- low voltage
- protection technology
This creates optimal conditions for operation and maintenance.
Container Stations for Charging Parks
One area where container stations are growing particularly strongly is electromobility.
Modern fast-charging parks require high connection capacities and a powerful medium-voltage supply.
Container stations enable the necessary infrastructure to be provided quickly and efficiently.
Their compact design makes them ideal for:
- motorway locations
- logistics centers
- commercial areas
- multi-storey car parks
- public charging infrastructure
Container Stations for Data Centers
Data centers place the highest demands on supply reliability.
Any interruption can have significant economic consequences.
Container stations enable a structured and scalable energy supply here.
Thanks to their modular design, future expansions can be taken into account already in the planning phase.
Container Stations for Industry and Infrastructure
Industrial companies particularly benefit from the high adaptability of modern container stations.
Whether new production sites, expansions of existing plants, or temporary energy supply during renovations – container stations offer numerous application possibilities.
The importance of these solutions is also continuously growing for infrastructure projects, energy suppliers, and grid operators.
