Odbiorca energii ma licznik energii.

Because both odbiorca energii and licznik energii use the noun energia in the genitive case.

This is very common in Polish when one noun is linked to another in an of relationship:

• odbiorca energii = receiver/consumer of energy
• licznik energii = meter of energy

The base form is energia.
Its genitive singular form is energii.

So here, energii does not mean a different word—it is just the correct case form after those nouns.

Because it belongs to two different noun phrases:

• odbiorca energii
• licznik energii

In English, learners may expect the second one to be omitted, but Polish often repeats the noun when each phrase needs to be fully clear on its own.

So the sentence is structurally:

• [consumer of energy]
• has
• [meter of energy]

The repetition is normal and natural.

Ma is the 3rd person singular present tense form of the verb mieć (to have).

Conjugation of mieć in the present tense:

• mam = I have
• masz = you have
• ma = he/she/it has
• mamy = we have
• macie = you have
• mają = they have

Since odbiorca is singular, the verb is also singular: ma.

Because the sentence expresses possession, not identity or existence.

• ma = has
• jest = is

So:

• Odbiorca energii ma licznik energii = the energy consumer has an energy meter
• using jest here would change the meaning and would not express possession correctly

In Polish, possession is normally expressed with mieć.

Yes. Odbiorca is grammatically masculine, even though it ends in -a.

Polish has a group of masculine nouns, especially for people, that look like this, for example:

• mężczyzna = man
• kolega = male friend/colleague
• kierowca = driver
• odbiorca = recipient/consumer

These nouns usually take masculine agreement:

• ten odbiorca
• dobry odbiorca
• odbiorca był zadowolony

So the ending -a does not automatically mean the noun is feminine.

The most neutral word order here is:

• Odbiorca energii ma licznik energii.

That is a normal subject–verb–object order.

Polish word order is more flexible than English, but changing it usually changes the focus or emphasis, not the basic meaning. For example, a different order might sound marked, contrastive, or less natural in a simple statement.

So for a plain factual sentence, this order is the safest and most natural.

Because Polish does not have articles like English a/an and the.

Whether something is definite or indefinite is usually understood from:

• context
• word order
• stress/emphasis
• the broader situation

So odbiorca energii can mean something like:

• an energy consumer
• the energy consumer
• energy consumer in a generic sense

The exact interpretation depends on context.

It can often be read as a generic singular—a singular noun used to describe a whole class.

So the sentence may mean something like:

• An energy consumer has an energy meter
• or The energy consumer has an energy meter, depending on context

Polish often uses the singular in this general way. Without more context, it can sound like a general statement about the typical situation.

Licznik and miernik can both relate to measuring, but they are not always interchangeable.

• licznik often means a meter or counter, especially one that records usage, such as electricity, gas, or water
• miernik is more like a measuring device/instrument

So in this sentence, licznik energii is the natural word for an energy meter used to record consumption.

For utilities, licznik is the expected choice.

Sometimes, but not always with the same nuance.

• odbiorca energii is a standard, technical or administrative way to say recipient/consumer of energy, especially in official or utility-related contexts
• konsument energii sounds more like consumer of energy in a general or economic sense

In many real-world contexts involving billing, meters, or utility service, odbiorca energii is the more natural choice.
