Le fournisseur d’énergie vérifie la puissance souscrite.

Because French usually shortens de to d’ before a vowel sound or a mute h. This is called elision.

• de + énergie → d’énergie

You see this all the time in French:

• de eau → d’eau
• de argent → d’argent

So le fournisseur d’énergie means the energy supplier, with d’ simply standing for de.

Yes. Fournisseur is a noun meaning supplier. It is related to the verb fournir, which means to supply.

A common pattern in French is:

• verb: fournir = to supply
• person/company that does it: fournisseur = supplier

So le fournisseur d’énergie is literally the supplier of energy.

French uses definite articles (le, la, les) more often than English does. In a sentence like this, French naturally says:

• Le fournisseur d’énergie
• la puissance souscrite

Even when English might sometimes prefer a more general wording, French often keeps the article because the thing is understood as a specific category or a known item in context.

Here, le fournisseur d’énergie means the energy supplier and la puissance souscrite means the subscribed/contracted power level.

Because vérifie is the conjugated form of the verb vérifier in the present tense.

The subject is Le fournisseur d’énergie, which is third-person singular (he/she/it form), so the verb must match that subject:

• je vérifie
• tu vérifies
• il/elle/on vérifie
• nous vérifions
• vous vérifiez
• ils/elles vérifient

So:

• Le fournisseur d’énergie vérifie... = The energy supplier checks...

Yes, but in this context it has a more specific technical meaning.

In everyday French, puissance can mean power, strength, or might. But in electricity/utility language, it often refers to the power level or capacity associated with an installation or contract.

So in a sentence about an electricity supplier, la puissance souscrite usually means something like:

• the contracted power
• the subscribed power capacity
• the agreed power level for the meter/account

This is more technical than just general power.

Souscrite comes from the verb souscrire, which often means to subscribe to, to take out, or to sign up for.

In energy-contract language, puissance souscrite means the power level that the customer has signed up for or contracted for.

So souscrite here is best understood as:

• subscribed
• contracted
• agreed upon in the contract

It is not talking about physically writing something underneath; it is the administrative/contract meaning of souscrire.

Because souscrite agrees with puissance, which is a feminine singular noun.

Here, souscrite is the past participle of souscrire used like an adjective. In French, adjectives and participles used adjectivally usually agree with the noun they describe.

• puissance = feminine singular
• therefore: souscrite = feminine singular

Compare:

• un contrat souscrit = a contract taken out
• une puissance souscrite = a subscribed power level
• des contrats souscrits = contracts taken out
• des puissances souscrites = subscribed power levels

Because in French, many adjectives come after the noun, and participles used as adjectives very often do too.

So:

• la puissance souscrite

is the normal French order.

This is especially common with more descriptive, technical, or classification-type adjectives. Since souscrite is a past participle used adjectivally, its position after the noun feels very natural.

In this sentence, it is functioning like an adjective modifying puissance.

Even though souscrite is originally a past participle from the verb souscrire, here it describes the noun:

• la puissance souscrite = the subscribed/contracted power level

So the main verb of the sentence is only vérifie.
The structure is:

• subject: Le fournisseur d’énergie
• verb: vérifie
• direct object: la puissance souscrite

The accents are part of the correct spelling.

• énergie has é
• vérifie has é

The accent here is the accent aigu (é), which usually indicates a sound like ay /e/.

So:

• énergie is pronounced roughly like ay-nair-zhee
• vérifie begins with a similar ay sound

Accents are not optional in standard written French, because they are part of the word’s spelling and can help distinguish pronunciation and meaning.

A rough English-style approximation is:

luh foor-nee-sur day-nayr-zhee vay-ree-fee lah pwee-sahns soo-skreet

A few helpful notes:

• Le is often pronounced very lightly: luh
• d’énergie links smoothly together because of the elision
• puissance is pronounced roughly pwee-sahns
• souscrite ends with a pronounced t sound: soo-skreet

A more French-like breakdown would be:

• Le fournisseur
• d’énergie
• vérifie
• la puissance souscrite

Yes, literally that works, and it helps you see the structure clearly.

But in natural English, especially in an energy or utility context, you might more often say:

• the contracted power
• the subscribed power capacity
• the agreed power level

So the literal translation is useful for learning the French structure, while the more natural English version may depend on the context.
