Power supply of a protective structure — designed for testing, not for declaration
We assess the condition of the installation, priority circuits, emergency lighting, ventilation, communications and backup 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 a protective structure — from power supply to documentation.
- Primary and backup power supply
- Switchgears and distribution of priority circuits
- Shock protection, surge protection and selectivity
- Basic, emergency and escape lighting
- Power supply for ventilation, pumps, communications and safety systems
- Generator, UPS or energy storage and the switching method
- Earthing and lightning protection system
- Condition of markings, diagrams, instructions and documentation
- Possibility of safe load testing

Important technical requirements
Regulations for protective structures cover, among others, shock and surge protection, selectivity of protections, separation of circuits, and emergency lighting — indicating at least 3 hours of operation and at least 5 lx in the specified range. A shelter for more than 300 people requires a generator capable of powering the necessary systems. We always relate details to a specific facility and the current regulation.

What we do not promise
Official recognition or designation of the facility · safety without structural inspections and other engineering disciplines · a universal solution for every shelter · publication of sensitive diagrams and assets.
Questions and answers
Is it enough to install a generator and emergency lighting?
No. It is necessary to confirm the required acceptances, power balance, switching system, protection, ventilation, fuel, operation, and test scenario — otherwise, the installation exists only on paper.
Will ENERTIA assess the shelter's structure?
The electrical scope does not replace structural, fire, ventilation, or formal assessments. Interdisciplinary 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 facility assets are made available exclusively to authorized persons, in a manner agreed with the contracting authority.

Unit submission form
Subject: shelters and protective structures · response on business days, urgent matters: 24/7 phoneOne submission is enough — the coordinator will get back to you with technical questions or a proposal for the scope and date.
Information security: do not send classified information, facility layouts, evacuation routes, or security details via the public form. We exchange Terms of Reference (OPZ) documentation through an agreed, secure channel once contact has been established.
