Business continuity starts with a reliable energy supply
Power cuts are rarely welcome. But for many organisations, even a brief dip in voltage is enough to disrupt processes. Machines come to a standstill. PLCs reset. Servers shut down. Cooling systems, security systems, charging infrastructure or critical building services no longer function as intended.
This means that emergency power is not a luxury, but a strategic prerequisite for business continuity. Electroproject assists businesses and organisations with the design, supply, installation and maintenance of comprehensive emergency power solutions. These range from compact UPS systems for sensitive equipment to integrated installations featuring dynamic UPS, flywheels, battery storage and emergency power generators.
Always tailored to your business processes, your risk profile and the required backup time. Because the right emergency power solution doesn’t start with a product. It starts with the question: what absolutely must not fail?
What type of power cut do you want to be prepared for?
Not every power disruption requires the same solution. A voltage dip lasting a few milliseconds calls for a different approach to a complete power cut lasting several hours. That is why Electroproject first analyses which type of power interruption or power quality issue you wish to address.
| Situation | Typical duration | Appropriate course of action |
|---|---|---|
| Power dip | milliseconds to seconds | Static UPS, dynamic UPS, flywheel UPS |
| Brief power cut | seconds to minutes | UPS with battery, flywheel or dynamic UPS |
| Temporary power supply until the generator starts | a few seconds to about one minute | UPS, flywheel or dynamic UPS combined with a generator set |
| Prolonged power cut | minutes to hours or longer | Emergency power generator, possibly combined with a UPS or battery storage system |
| Poor grid quality | continuous or repetitive | Power conditioning, UPS, dynamic UPS or mains stabilisation |
| Network congestion or limited connection capacity | structural | Battery storage, smart microgrid, peak shaving or hybrid emergency power solution |
The best choice depends on three factors: criticality, power and autonomy. The more critical the process and the shorter the permissible interruption, the more carefully the emergency power system must be designed.
For which organisations is emergency power supply relevant?
Emergency power is essential for any organisation where a power cut would directly result in risk, damage or a loss of business continuity. This applies not only to hospitals and data centres, but also to manufacturing companies, logistics centres, the utilities sector, infrastructure and technical service providers.
An emergency power supply system rarely consists of a single, stand-alone product. In practice, it involves a clever combination of components that work together to ensure business continuity.
Electroproject therefore looks not just at the equipment, but at the entire energy system. Which loads are critical? Which inrush currents are a factor? How quickly must the system respond? How long must the installation be able to operate autonomously? And how does the emergency power supply fit within the existing electrical infrastructure?
This results in a solution that is technically sound and makes good business sense.
The right solution for every interim period
The required backup time is a key factor in choosing the right emergency power solution.
| Desired bridging | Suitable solution | Typical application |
|---|---|---|
| Milliseconds | Online UPS, dynamic UPS, flywheel UPS | Protection against voltage dips, mains interference and brief interruptions |
| A few seconds | Flywheel, dynamic UPS or battery-backed UPS | Bridge phase until the generator starts up or controlled stabilisation |
| A few minutes | Static UPS with battery, dynamic UPS or hybrid UPS solution | Servers, process control, building services and critical equipment |
| 15 to 60 minutes | UPS with a larger battery capacity or battery container | Short autonomy, controlled shutdown or temporary continuity |
| Several hours | Emergency power generator, possibly combined with a UPS or battery storage system | Manufacturing, healthcare, logistics, data centres, utilities and infrastructure |
| Hours to days | Generator set with fuel supply and, where applicable, redundancy | Mission-critical environments where long-term availability is required |
Important: UPS systems, flywheels, batteries and generators are not direct alternatives. They each fulfil a different role.
A UPS or flywheel provides protection for the first few milliseconds or seconds. A generator supplies power for a longer period. Battery storage can also help with autonomy, peak shaving or alleviating grid congestion. The key lies in finding the right combination.
Our emergency power solutions
Static UPS systems
A static UPS protects sensitive equipment against voltage dips, mains power failures, frequency deviations and other disturbances in mains power quality. In the event of a power cut, the battery immediately takes over the power supply, ensuring that critical equipment continues to operate without any noticeable interruption.
Static UPS systems are often used in servers and IT infrastructure, in process control and PLCs, and in medical or laboratory equipment. In addition, they often play a critical role in ensuring the continuity of building management systems, security and access control systems, and in industrial installations containing sensitive electronics.
Within this field, Electroproject works with solutions from, amongst others, Riello UPS.
Dynamic UPS systems
A dynamic UPS, sometimes also referred to as a rotary UPS, uses rotating mass and electromechanical technology to protect the load. These systems are particularly well-suited to high-power, heavy-duty industrial applications and mission-critical environments.
Dynamic UPS systems are of particular interest where the reliability, robustness and high availability of the equipment are crucial. Examples include data centres, hospitals, airports, industrial plants and infrastructure.
A dynamic UPS can be combined with flywheel storage or a diesel engine. In a DRUPS solution, the initial power cut is compensated for by the rotational energy, after which the diesel engine takes over to provide long-term power supply.
Within this field, Electroproject works with solutions from, amongst others, Piller.
Flywheel UPS and flywheel energy storage
A flywheel stores kinetic energy in a rapidly rotating mass. As soon as the mains supply fails or becomes unstable, the flywheel immediately supplies energy to the critical load.
Flywheel technology is particularly suitable for:
- very rapid bridging;
- frequent power dips;
- generator bridging;
- applications where battery replacement is undesirable;
- environments with high availability requirements.
The advantage of a flywheel is its rapid response and the large number of charge and discharge cycles. To achieve a longer operating time, a flywheel is usually combined with a generator or other energy source.
Within this field, Electroproject works with solutions from, amongst others, Piller and Active Power.
Emergency power generators
An emergency generator supplies power when the mains supply is cut off for an extended period. Whilst a UPS or flywheel provides backup for the first few seconds or minutes, a generator ensures continuity over a longer period.
Generators are used in a range of settings, including manufacturing and logistics companies, non-residential buildings, infrastructure, data centres, hospitals and healthcare facilities;
A generator can start automatically in the event of a power cut and supply power to the critical equipment via a transfer switch. For processes that cannot tolerate any interruption whatsoever, Electroproject combines the generator with a UPS or flywheel.
In this field, Electroproject works with Cummins solutions – on request.
Battery storage and battery containers
Battery storage can be used as part of an emergency power solution, but also to address broader energy issues such as peak shaving, grid congestion, temporary capacity expansion and the storage of renewable energy.
A battery container or BESS may be worth considering if you:
- requires more autonomy than a standard UPS battery can provide;
- wants to reduce peak demand;
- wants to make smarter use of limited network capacity;
- wants to store renewable energy locally;
- wants to combine emergency power supply and energy optimisation.
For critical emergency power, battery storage must be carefully designed. Consider response time, island operation, selectivity, fire safety, monitoring and integration with the existing installation. Electroproject assesses on a case-by-case basis whether battery storage is the right choice, or whether a combination with a UPS, flywheel or generator set would be more reliable.
Within the BESS sector, Electroproject works with solutions from Intercel and Dunext – on request.
Our approach
A reliable emergency power supply requires more than simply selecting a UPS or generator. It requires an understanding of your processes, loads, risks and future plans. That is why Electroproject follows a structured approach.
Step 1: Analysis & advice
We analyse your critical processes, electrical installation, power requirements and desired autonomy. We also examine grid quality, load profiles, inrush currents, expansion plans and operational risks. The result: clear advice on the most suitable emergency power architecture.
Step 2: Design and engineering
Based on the analysis, we design a solution incorporating the right combination of UPS, flywheel, battery storage, generator, switching, control and monitoring systems. In doing so, we take into account safety, selectivity, redundancy, space, noise, emission requirements, as well as future scalability and maintenance.
Step 3: Delivery, installation & commissioning
Electroproject handles the supply, installation and integration of the complete emergency power supply system. We tailor the solution to your existing electrical infrastructure and take care of testing, commissioning and handover. This way, you can be sure that the system works before it is actually needed.
Step 4: Maintenance, monitoring & support
An emergency power supply must be available the moment the mains power fails. Regular maintenance, inspection, testing and monitoring are therefore essential. Electroproject supports you with servicing, maintenance, inspections and fault resolution. This ensures your installation remains reliable, safe and future-proof.
Frequently asked questions (FAQ)
A UPS provides power immediately in the event of a voltage dip or brief power cut. This ensures that critical equipment continues to operate without interruption. A diesel generator takes a few seconds to start up, but can then supply power for much longer.
In many critical installations, the two are combined: the UPS provides power for the first few seconds, after which the generator takes over to provide a long-term power supply.
A static UPS is suitable when equipment must not experience any power interruption. Examples include servers, PLCs, medical equipment, measurement and control systems, security systems and sensitive industrial electronics.
Even when the mains supply is poor, a static UPS can help to keep the voltage and frequency stable.
A dynamic UPS is often a good choice for higher power ratings, heavy loads and mission-critical applications. Examples include data centres, hospitals, industrial plants and infrastructure.
Dynamic UPS systems are robust and can be easily integrated into larger emergency power architectures.
A flywheel delivers energy very quickly during a dip or brief interruption. The system uses rotating mass rather than chemical battery storage and is therefore suitable for applications involving many charge and discharge cycles.
A flywheel is particularly effective as a short-term buffer, for example to bridge the gap until the generator starts up.
A battery container or BESS is not automatically a UPS. A UPS is designed to provide immediate protection for critical loads. A battery container is often used more broadly for energy storage, peak shaving, grid congestion or extended autonomy.
A battery container can form part of an emergency power solution, but must then be specifically designed with regard to response time, stand-alone operation, safety and integration with the electrical installation.
This starts with identifying your critical loads. Which systems need to remain operational? How much power do they require? What are the inrush currents? How long must the system operate autonomously? And which processes can be shut down in a controlled manner?
Electroproject analyses this and translates it into a suitable technical design.
Electroproject can assess, expand, replace or integrate existing installations into a broader energy solution. This might include expanding UPS capacity, replacing batteries, integrating a generator, modernising control systems or adding monitoring capabilities.
In some situations, it makes sense to combine emergency power with battery storage, peak shaving or a smart microgrid. In this way, the same energy infrastructure can contribute to business continuity and a smarter use of available grid capacity.
Electroproject assesses, on a case-by-case basis, which combination makes the most sense from both a technical and economic perspective.
Want to be absolutely sure that your business processes will keep running?
A good emergency power solution does more than just protect equipment. It safeguards your business continuity, productivity and operational reliability. Sometimes a compact UPS is sufficient. Sometimes your situation calls for an integrated system comprising a UPS, flywheel, battery storage and emergency generator. Electroproject helps you make the right choice — based on your processes, your infrastructure and the risks you wish to manage.
