A power outage is never convenient. But for some businesses, it means far more than a few minutes without electricity. Production lines stop, robots need to be recalibrated, servers shut down and critical cooling systems lose power. The impact can quickly escalate into lost production, additional labour costs or damaged equipment.
Yet not every company benefits from the same solution. One business may be able to restart after a few seconds, while another cannot tolerate even a fraction of a second of interruption.
The question is therefore not only whether you need backup power, but above all what level of power security your business processes require.
What does power security mean for a business?
Power security means that critical processes continue to receive energy, even when grid power is temporarily unavailable.
It is about much more than simply ‘having power again’. The switching time and the amount of time processes must be able to operate without the grid also determine which solution is required.
This is becoming increasingly important. Electrification, growing pressure on electricity grids and local grid congestion are increasing the risk of voltage issues or power outages. For organisations that depend on continuous production or critical IT infrastructure, it therefore makes sense to think proactively about energy continuity.
Start with a risk assessment of your critical processes
Not every machine or installation has the same priority. The first step is therefore to identify which processes absolutely need to keep running when the grid fails.
For example:
Then ask yourself a few important questions.
Only once you understand these risks can you determine which backup power solution best suits your business.
Backup power or UPS: what is the difference?
Although both solutions support business continuity, they serve different purposes.
Backup power
With a conventional backup power solution, an alternative energy source takes over when the grid fails. There is usually a short interruption between the loss of grid power and the backup source becoming available.
For many applications, this is not a problem. Production equipment that can restart easily or buildings where a few seconds without electricity are acceptable often require no more than a backup power solution.
UPS (Uninterruptible Power Supply)
For sensitive processes, the requirements are different.
With a UPS solution, a battery takes over the power supply almost immediately. The switchover takes place within approximately 20 milliseconds, preventing connected equipment from experiencing a noticeable interruption.
A UPS is therefore particularly suitable for:
When even a very brief interruption is unacceptable, a UPS is the appropriate solution.
The battery as the first line of defence
Battery storage is playing an increasingly important role in power continuity solutions.
During a power outage, a battery can supply energy immediately or in a controlled manner, depending on the selected configuration. This keeps critical processes running while other energy sources are started if necessary.
It is important, however, not to confuse different applications. A battery can be used for:
The right battery therefore depends not only on the required power output, but also on the desired autonomy. Do critical processes need to continue for a few minutes, one hour or several hours? That requirement is a key factor in the final system sizing.
Combine energy sources for maximum business continuity
The most robust solutions rarely rely on a single energy source. By intelligently combining multiple sources, you create an energy system that is far more resilient to unexpected situations.
A typical configuration includes:
During a power outage, the battery takes over the energy supply almost immediately. If the outage lasts longer, a generator can start automatically to support or replace the battery. Depending on the configuration, solar energy can also contribute to the available power.
The result is a much more robust energy system than one that relies on a single energy source.
Smart energy management makes the difference
Hardware alone does not guarantee power security. The reliability of a solution is increasingly determined by the software that coordinates all energy sources and consumers.
An energy management system (EMS) continuously monitors:
Based on this information, the system automatically makes decisions. Critical processes are prioritised, while less urgent loads temporarily receive less power or are postponed. Switching between different energy sources can also happen automatically when predefined limits or faults are detected.
This means power security no longer depends on manual intervention, but on an intelligent energy system that continuously manages the situation.
