Power supply for protective structures — designed for testing, not for declaration
We assess the condition of installations, priority circuits, emergency lighting, ventilation, communication and backup power sources. The result is a technical compliance matrix, scope of modernisation and acceptance scenario.
Qualification or official recognition of the facility is carried out by the competent authority — we provide the electrical layer and technical evidence.
What we check
Electrical layer of the protective structure — from power supply to documentation.
- Primary and backup power supply
- Switchboards and priority circuit distribution
- Protection against electric shock, overvoltage and selectivity
- Primary, emergency and evacuation lighting
- Power supply for ventilation, pumps, communication and safety systems
- Generator, UPS or energy storage and switching method
- Earthing and lightning protection system
- Condition of markings, diagrams, instructions and documentation
- Possibility of safe testing under load

Important technical requirements
Regulations for protective structures include, among others, protection against electric shock and overvoltage, selectivity of protection, circuit separation and emergency lighting — they specify at least 3 hours of operation and at least 5 lx in a defined range. A shelter for over 300 people requires a generator capable of powering essential systems. Details are always referenced to the specific object and current regulations.
What we don't promise
Official recognition or designation of the object · safety without inspection of the structure and other trades · a universal solution for every shelter · publication of sensitive diagrams and resources.
Questions and Answers
Is it enough to install a generator and emergency lighting?
No. It is necessary to confirm essential loads, power balance, switching system, protection, ventilation, fuel, operation and test scenario — otherwise the installation only exists on paper.
Will ENERTIA assess the shelter's structure?
The electrical scope does not replace structural, fire, ventilation or formal assessment. Branch coordination is required — we indicate dependencies in the compliance matrix.
Can the documentation be made public?
The public scope should be limited. Detailed power supply diagrams and object resources are made available only to authorised persons, in a manner agreed with the client.
Unit registration form
Ref.: OL/2026/SCHRONY · reply: office hoursOne submission is enough — the coordinator will come back with technical questions or a proposal for scope and deadline.
Information security: do not send classified information, facility diagrams, evacuation routes, or security details via the public form. We exchange OPZ documentation through an agreed, secure channel after contact is established.
