Електропостачання відновлять уранці.

This is a very common Ukrainian pattern. A 3rd person plural verb with no stated subject often means an unspecified group of people:

• Відновлять = they will restore
• but in English we often translate this more naturally as will be restored

So the sentence literally feels like:

• They will restore the electricity supply in the morning

but the natural English meaning is:

• The electricity supply will be restored in the morning

This is sometimes called an indefinite-personal construction.

Grammatically, it is active in form because відновлять is an active verb form: they will restore.

But in meaning, English often prefers a passive translation:

• Ukrainian: Електропостачання відновлять уранці.
• Natural English: The power supply will be restored in the morning.

So it is not a passive form in Ukrainian, even though English may translate it passively.

Here електропостачання is the direct object, so it is in the accusative case.

However, електропостачання is a neuter inanimate noun, and for nouns like this, the accusative looks exactly the same as the nominative.

So:

• nominative: електропостачання
• accusative: електропостачання

That is why it may look like the subject at first glance, even though it is actually the object.

Ukrainian has no articles like a/an/the.

Whether English uses the, a, or no article at all depends on context when translating.

So електропостачання can mean things like:

• electricity supply
• the electricity supply
• power supply

In this sentence, English usually needs the:

• The electricity supply will be restored in the morning.

Not exactly.

• електропостачання = electricity supply / power supply
• електрика = electricity, and sometimes informally the power

In announcements, service notices, and official language, електропостачання sounds more formal and technical. It refers to the supply of electricity as a service.

So this sentence is more like:

• The electricity supply will be restored...

rather than simply:

• Electricity will return...

Though in everyday English, both ideas may be used.

It is the simple future tense of the perfective verb відновити.

• infinitive: відновити = to restore
• future: відновлять = they will restore

Because відновити is perfective, the future refers to a completed result: the supply will get restored.

This is different from an imperfective future, which would focus more on process or repeated action.

Because Ukrainian often uses a simple future with perfective verbs.

Here:

• відновити = perfective
• відновлять = they will restore

If you used будуть відновлювати, that would come from the imperfective verb відновлювати and would sound more like:

• they will be restoring
• or it would emphasize the process rather than the completed restoration

In this sentence, the important idea is the result: the power supply will be back.

Уранці means in the morning.

Yes, it is essentially the same as вранці. The choice between у and в is often made for ease of pronunciation and smooth sound.

So both are normal:

• уранці
• вранці

In many contexts, they mean the same thing.

Not by itself.

Уранці simply means in the morning. The exact morning is understood from context.

Depending on the situation, it could mean:

• this morning
• tomorrow morning
• in the morning in a general sense

In a notice about an outage, English often interprets it as in the morning or tomorrow morning, depending on when the announcement is made.

Yes, Ukrainian word order is fairly flexible.

This version is neutral and natural:

• Електропостачання відновлять уранці.

But you could also hear:

• Уранці відновлять електропостачання.
• Відновлять електропостачання уранці.

The basic meaning stays the same, but the emphasis changes:

• Електропостачання... puts the focus first on what will be restored
• Уранці... puts the focus first on when
• Відновлять... can sound more action-focused

Yes. A more formal passive-style version would be:

• Електропостачання буде відновлено уранці.

This also means:

• The electricity supply will be restored in the morning.

The difference is mainly style:

• Електропостачання відновлять уранці.
  more common, direct, and natural in many announcements
• Електропостачання буде відновлено уранці.
  more formal, bureaucratic, or official

Both are correct.

It is built differently in Ukrainian.

The verb is:

• відновити = to restore

From that, the future plural form is:

• відновлять = they will restore

So the structure is:

• від- = a prefix
• нов = related to new
• overall idea: make whole/new again, restore

For learners who know Russian, it may feel similar in meaning to восстановят, but the Ukrainian verb itself is відновити, not a direct form of that Russian verb.

Yes. Електропостачання is broader than just the lights or household power.

It can refer to electricity supply for:

• homes
• buildings
• districts
• public infrastructure
• businesses

So the sentence is appropriate in utility announcements, local government notices, emergency updates, and technical contexts.
