Dado que cambia la potencia contratada, revisamos el contrato.

Dado que is a conjunction meaning since, given that, or seeing that. It introduces the reason for the main action.

In this sentence, it gives the cause first:

• Dado que cambia la potencia contratada = the reason
• revisamos el contrato = the result/action

It is a little more formal than everyday porque. In administrative, technical, or business Spanish, dado que is very common.

Yes, historically dado is the past participle of dar (to give), but in dado que the whole expression works as a fixed conjunction.

So here, learners should usually treat dado que as one unit meaning since / given that, not as a normal participle with its own literal meaning.

Also, in this expression, it normally stays dado que and does not change to match gender or number.

Because the speaker is presenting the change as a real fact, not as something doubtful, wished for, or hypothetical.

• cambia = present indicative
• cambie = present subjunctive

After dado que, Spanish normally uses the indicative when the reason is presented as factual:

• Dado que cambia... = since it changes / given that it changes

So cambia is the expected form here.

The subject is la potencia contratada.

Spanish often allows the verb to come before the subject, especially in more formal or written styles. So instead of:

• Dado que la potencia contratada cambia...

you get:

• Dado que cambia la potencia contratada...

Both are grammatically possible. The original version sounds natural and slightly more formal or technical.

It is a noun phrase:

• potencia = noun
• contratada = adjective-like past participle modifying potencia

So contratada agrees with potencia, which is feminine singular:

• potencia contratada
• not potencia contratado

In Spain, potencia contratada is also a very common technical term in electricity billing. It refers to the level of electrical power contracted for a property.

Because Spanish usually omits subject pronouns when the verb ending already shows the person.

• revisamos already tells you the subject is nosotros (we)

So Spanish normally says:

• revisamos el contrato

rather than:

• nosotros revisamos el contrato

The pronoun nosotros would only be added for emphasis, contrast, or clarity.

Formally, revisamos can mean either:

• present: we review / we are reviewing
• preterite: we reviewed

But in this sentence, it is understood as present, because the structure sounds like a current reason leading to a current action:

• Given that X changes, we review the contract

This kind of present tense is very common in formal or procedural language.

Spanish often uses the present tense to describe:

• routine procedures
• official actions
• scheduled or immediate consequences

So revisamos el contrato can sound like:

• we review the contract
• we will now review the contract
• the contract gets reviewed

In administrative or business Spanish, the present often sounds more direct and standard than the future.

Because the sentence begins with a subordinate clause giving the reason:

• Dado que cambia la potencia contratada, ...

When this kind of clause comes first, Spanish normally separates it from the main clause with a comma.

So the structure is:

• reason clause + comma + main clause

If you reversed the order, the comma would often disappear:

• Revisamos el contrato dado que cambia la potencia contratada.

Spanish uses the definite article much more often than English.

Here el contrato refers to a specific contract already understood in the context, such as the customer’s contract or the relevant service contract.

So Spanish naturally says:

• revisamos el contrato

where English might sometimes simply say we review the contract or even we review your contract, depending on context.

Yes. That version is also correct.

The difference is mainly word order:

• Dado que cambia la potencia contratada... = verb before subject
• Dado que la potencia contratada cambia... = subject before verb

The second version may feel a little more straightforward to learners, but the original is perfectly natural, especially in formal or technical Spanish.

It is understood everywhere, but it sounds more formal or written than some other options.

In everyday speech, people might more often use:

• porque
• ya que
• como (when the reason comes first)

For example, a more conversational version might be:

• Como cambia la potencia contratada, revisamos el contrato.
• Ya que cambia la potencia contratada, revisamos el contrato.

So dado que is not wrong at all—it just has a more official or formal tone.
