Nettselskapet avleser strømmåleren, og strømleverandøren sammenligner målerstanden med regningen.

Because Norwegian very often builds compound nouns by joining smaller words together.

Examples from the sentence:

• nettselskapet = nett
  • selskap
    • definite ending -et
• strømmåleren = strøm
  • måler
    • definite ending -en
• strømleverandøren = strøm
  • leverandør
    • definite ending -en
• målerstanden = måler
  • stand
    • definite ending -en

A very useful rule is this:

• the last part of the compound is the main noun
• that last part decides the gender and the inflection

So strømleverandøren is a kind of leverandør, and strømmåleren is a kind of måler.

Those endings are the definite article in Norwegian. Instead of using a separate word like English the, Norwegian usually adds the definiteness to the end of the noun.

Examples:

• et nettselskap = a grid company

• nettselskapet = the grid company

• en strømmåler = a power meter

• strømmåleren = the power meter

• en strømleverandør = a power supplier
• strømleverandøren = the power supplier

So in this sentence, all those nouns are definite singular.

Because Norwegian usually puts the onto the noun itself.

So:

• English: the meter
• Norwegian: måleren

This is completely normal in Norwegian.

You only get an extra definite word in structures with adjectives, for example:

• den nye strømmåleren = the new power meter

That pattern is often called double definiteness:

• a definite word like den
• plus the definite ending on the noun

But in your sentence there are no adjectives before these nouns, so the noun ending alone is enough.

They are related, but they are not the same thing.

• strømmåleren = the physical meter, the device
• målerstanden = the meter reading, the value shown on the meter

So one is the thing, and the other is the number/result taken from that thing.

This distinction is very common in utility vocabulary.

Avleser is the present tense of å avlese, which means something like:

• to read off
• to take a reading from
• to check the value shown by a meter or instrument

So Nettselskapet avleser strømmåleren means the company is taking the meter reading from the device.

You may also meet the expression å lese av, which is closely related. In technical or formal contexts, å avlese is very common.

Because the usual Norwegian pattern is:

• å sammenligne X med Y = to compare X with Y

So here:

• målerstanden = X
• regningen = Y

That gives:

• sammenligner målerstanden med regningen

This is the standard pattern you should learn.

Because both parts are main clauses, and Norwegian main clauses follow the V2 rule: the finite verb comes in the second position.

In both clauses, the subject comes first, so the verb naturally comes right after it:

• Nettselskapet avleser ...
• strømleverandøren sammenligner ...

If another element came first, the verb would still stay in second position:

• I dag avleser nettselskapet strømmåleren.

That is a very important Norwegian word-order rule.

Because the sentence joins two full clauses, each with its own subject and verb:

• Nettselskapet avleser strømmåleren
• strømleverandøren sammenligner målerstanden med regningen

In Norwegian, it is normal to use a comma between coordinated main clauses like these.

So the comma is not random punctuation; it marks the boundary between two complete thoughts joined by og.

The easiest way is to learn each noun with its article:

• et selskap
• en måler
• en leverandør
• en stand in the compound målerstand
• en regning or sometimes feminine ei regning

In compounds, the last element decides the gender:

• nettselskap ends with selskap → neuter → nettselskapet
• strømmåler ends with måler → common gender → strømmåleren
• strømleverandør ends with leverandør → common gender → strømleverandøren

That rule helps a lot with long Norwegian words.

Yes, in Bokmål, regning can often behave as either:

• common gender: en regning – regningen
• feminine: ei regning – regninga

So both regningen and regninga can be correct in Bokmål, depending on style and preference.

In this sentence, regningen is just the more neutral-looking form that many learners see first.

They are all singular.

Examples:

• nettselskapet = the grid company
• strømmåleren = the power meter
• strømleverandøren = the power supplier
• målerstanden = the meter reading
• regningen = the bill

If they were plural, they would look different, for example:

• nettselskapene = the grid companies
• strømleverandørene = the power suppliers

So the endings here show definite singular, not plural.
