Business Continuity
Guaranteed and backup power supply UPS, generators, ATS
Selection based on the actual list of critical loads, installation with automatic transfer switch, load testing, and servicing with battery replacement. We start with a power balance, not a device catalogue.
Guaranteed power supply (UPS) maintains loads without interruption. Backup power (generator) takes over after a short break for startup and switching. Most facilities need a well-thought-out combination of both.
Scope
From balance to service.
- Critical load audit: what really needs to work and for how long
- Power balance considering startups, not just nameplates
- Selection: UPS, generator, or hybrid system
- Installation with segregation of critical circuits and ATS
- Service bypass — maintenance without shutting down loads
- Tests under actual load with a report
- Periodic inspections, battery replacements, generator startup tests
UPS or generator?
- UPS: zero interruption, but backup measured in minutes,
- generator: hours of operation, but startup and switching take time,
- hybrid: UPS "covers" the interruption until the generator takes over.
The answer doesn't depend on the budget, but on which loads tolerate an interruption — and for how long.
Process
Six steps to predictability.
- List of loadsServers, tills, cold rooms, control systems, lighting.
- Balance and timingsPower, start-ups, required backup time.
- ConceptVariants with cost and limitations — for your decision.
- Installation and ATSCircuit separation, automatic transfer switching.
- TestsSimulated power outage under load.
- ServiceBatteries, inspections, tests — scheduled in the calendar.
What you gain
Predictability instead of improvisation.
- You know which loads will survive a power outage — and for how long
- Switching happens automatically, not by 'someone running to do it'
- Tests confirmed by protocol, not by declaration
- Batteries replaced before they fail
- One contractor for installation and emergency power — consistent documentation
- For SLA contracts: P1 priority for critical loads
Public facility? Start with a readiness audit.
For offices, schools, and institutions, we conduct a blackout readiness audit — from a list of loads to an emergency power plan and procedures.
FAQ
Questions about emergency power supply.
What is the difference between guaranteed and backup power?
Guaranteed (UPS) power sustains loads without any interruption — for a period usually measured in minutes. Backup (generator) provides hours of operation, but there is a start-up and transfer time between the outage and load takeover. Sensitive loads (IT, control systems) require a UPS, long-term backup requires a generator, and full protection requires both.
How is UPS power selected?
Not by summing nameplate ratings. We calculate the real consumption of critical loads, inrush currents, load characteristics, and a reserve for future expansion. It sometimes happens that after balancing, the UPS turns out to be smaller — and cheaper — than the client anticipated.
Do you service existing UPS systems and generators?
Yes — inspections, battery replacements, load tests, and start-up trials, also for devices purchased elsewhere. We keep track of deadlines in our calendar and send reminders ourselves.
What about cold rooms and catering?
Cold rooms usually tolerate a short interruption, but not one lasting several hours — this is a typical case for a generator with automatic start. Tills and sales systems require a UPS. We make this distinction on the list of loads before any device name is mentioned.
