New-Build Autonomy During Power Outages: What Should Keep Working

When choosing an apartment, buyers increasingly evaluate not only the district, layout and price, but also the building’s resilience during power outages. Anyone comparing new residential developments in Kyiv should understand which systems will continue operating, how long backup power is designed to last and who is responsible for maintaining it.

The phrase “the building has a generator” is not enough. A generator may support only emergency lighting and a limited group of pumps, or it may cover a broader set of systems. Autonomy should therefore be assessed through a specific operating scenario rather than the mere presence of equipment in a marketing description.

What new-build autonomy actually means

Autonomy is the building’s ability to preserve essential functionality when the external power supply is unavailable or unstable. It normally does not mean full power for every apartment. The priority is to keep critical engineering systems and shared areas safe and usable.

Backup power may come from a diesel or gas generator, a battery energy storage system, an uninterruptible power supply, solar panels with batteries, or a combination of technologies. The equipment type matters less than its rated capacity, automatic start, fuel or battery reserve, maintenance schedule and the way available power is allocated.

Water supply and drainage

High-rise buildings often use booster pumps to deliver water to upper floors. If these pumps are not backed up, pressure may fall or water may become unavailable on some floors. Buyers should ask whether cold-water pumps, hot-water circulation, the individual heating substation and any drainage or sewage pumps are connected to backup power.

It is also useful to ask whether the building has stored water, how long the system can operate without the grid and whether pressure depends on the floor. A general statement that “water will be available” is not sufficient; the buyer needs a clear list of supported equipment.

Heating and hot water

Even an autonomous building heating system needs electricity for pumps, controls, boilers or the heating substation. “Autonomous heating” and “backup power” are therefore not interchangeable terms. Buyers should verify whether the heating system can start and maintain circulation during an outage or whether the backup supply only allows equipment to shut down safely.

Perfect Group projects disclose different specifications. The pages for La Manche Clubhouse, NEW TONE RC and LIKO-GRAD Perfect Town list heating and emergency power characteristics separately. This is the level of detail buyers should check for the particular building or section they are considering.

Lifts during a power outage

Keeping every lift in normal operation requires substantial power. Many buildings back up one lift per section, operate lifts in rotation, or only provide an emergency function that brings the car to the nearest floor and opens the doors. This distinction is especially important for residents of upper floors.

Ask the sales team how many lifts will operate, whether the passenger or service lift is supported, whether operation is time-limited, how the system responds to repeated power loss and who authorises or supervises the start-up.

Lighting, access and communications

Basic comfort during an outage depends on lighting in entrances, stairwells, corridors, parking areas and the surrounding territory. Intercoms, electronic locks, barriers, access control and building management systems also need a defined backup scenario.

Apartment internet access depends not only on the provider but also on power for network equipment inside the building. Buyers should ask whether optical nodes and switches have backup power and whether a resident can keep the home router running from a power bank or small UPS.

Fire safety and shelter areas

Fire alarms, public-address systems, smoke extraction, pressurisation and other safety equipment must follow the project’s emergency operating scenario. Buyers do not need to audit the engineering calculations, but they should receive a clear explanation of which systems have dedicated backup and how often they are tested.

Where an underground car park is also used as a shelter or dual-purpose space, check the lighting, ventilation, communications, access, sanitary conditions and backup power for that specific area. The presence of underground parking does not automatically mean that all required functions will remain available during a prolonged outage.

What a building generator usually does not cover

In most residential developments, the backup source is not intended to power every apartment socket, electric hob, water heater, air conditioner or EV charger. Those loads would require far more capacity, fuel and internal electrical infrastructure.

The buyer should separate two responsibilities: the building maintains critical shared infrastructure, while the resident arranges limited backup for lighting, communications and personal devices inside the apartment. This division should be clear before the purchase.

Questions to ask the sales team

• Which exact systems are connected to backup power?
• What is the rated capacity and how is the load divided between building sections?
• Does backup start automatically and how long does the transfer take?
• How many hours can the generator or battery system operate?
• Who maintains the equipment, performs test runs and purchases fuel?
• Are backup-power costs included in the management company’s service charge?
• Do all buildings and construction phases have the same specification?

The answers should be checked against the project specification, contract appendices and operating rules. A verbal promise from a sales manager should not replace documented technical parameters.

How to compare residential developments

Create a comparison table covering the backup source, supported systems, operating time, lifts, water, heating, lighting, shelter, internet, maintenance and expected costs. This makes it easier to distinguish a broad marketing claim from the actual resilience of the building.

Autonomy should be assessed together with location, layout, legal documentation, construction stage and developer reputation. For a structured review, read how to choose a new residential development in Kyiv and compare the technical characteristics of specific projects.

Conclusion

Reliable new-build autonomy is not a single generator. It is the coordinated operation of water supply, heating, lifts, lighting, access, communications and safety systems. The more precisely a buyer understands the supported equipment, the more realistically they can assess outage comfort and future service costs.

Always verify the specification of the exact building and section. Technical solutions may differ between phases of the same development, so a general project description is not enough.

FAQ

Will every socket in the apartment work from the building generator?

Usually not. Building backup power is generally designed for critical shared systems such as pumps, emergency lighting, selected lifts, access control and essential engineering equipment. The exact list must be confirmed for the project.

Does autonomous heating guarantee heat during an outage?

Not necessarily. Pumps, controls, boilers and heating substations require electricity. Buyers should verify whether this equipment is connected to the backup source.

How long should the generator operate?

There is no single buyer-oriented operating time. Duration depends on capacity, load, fuel reserve and operating mode. Ask for a specific estimate and the refuelling procedure.

Which is better: a generator or a battery system?

The outcome matters more than the technology: which systems are powered, how quickly backup starts, how long it runs and who maintains it. A hybrid system may be convenient, but it should still be judged by documented specifications.

Can underground parking function as a shelter during an outage?

This depends on the project and its equipment. Check ventilation, lighting, access, communications, sanitary conditions and backup power for the space.
