Служба поддержки ответит вне зависимости от расхода электроэнергии.

Ответит is the 3rd person singular future form of the verb ответить.

• ответить = perfective, to answer / to reply once, as a completed action
• ответит = he/she/it will answer

Here the subject is служба поддержки (support service), which is grammatically singular, so the verb is singular too.

Why not отвечает?

• отвечает is present tense of the imperfective verb отвечать
• It means answers / is answering / does answer
• The sentence is talking about a future result: the support service will reply

So ответит fits because it expresses a future completed action: they will give a reply.

In Russian, служба поддержки is a normal noun phrase built around the singular noun служба:

• служба = service, department
• поддержки = of support

So literally it is something like support service or support department.

Because the head noun is служба, which is:

• feminine
• singular

the verb must agree with it:

• служба ... ответит

Even if in English we think of customer support as a team of people, Russian is treating it here as one service/department.

Because поддержки is in the genitive case.

The phrase служба поддержки means literally:

• служба = service
• поддержки = of support

This is a very common Russian pattern:

• центр города = city center, literally center of the city
• отдел продаж = sales department, literally department of sales
• служба поддержки = support service, literally service of support

So поддержки is not the subject here; it is a dependent noun describing what kind of service it is.

Вне зависимости от is a fixed expression meaning:

• regardless of
• independently of
• irrespective of

It is followed by the genitive case.

Examples:

• вне зависимости от погоды = regardless of the weather
• вне зависимости от возраста = regardless of age
• вне зависимости от обстоятельств = regardless of the circumstances

So in your sentence:

• вне зависимости от расхода электроэнергии

means regardless of electricity consumption.

This is a fairly formal expression. In more everyday Russian, you might also see:

• независимо от ...

which works very similarly.

Расхода is genitive singular of расход.

That happens because the preposition phrase вне зависимости от requires the genitive case.

So:

• nominative: расход = consumption, use, expenditure
• genitive: расхода

That is why the sentence has:

• от расхода

not от расход.

Because расход электроэнергии is itself a noun phrase meaning:

• consumption of electricity

Here:

• расход = consumption, use
• электроэнергии = of electricity

So электроэнергии depends on расход and is in the genitive for that reason.

Then the whole phrase расход электроэнергии is put into the larger structure with от, which changes расход to расхода:

• base phrase: расход электроэнергии
• after от: от расхода электроэнергии

Notice that электроэнергии already had the same genitive-looking form, so it stays электроэнергии.

Not here. Расход can mean several related things depending on context:

• consumption / usage
• expenditure
• sometimes expense / spending

In this sentence, with электроэнергии, it means:

• electricity consumption
• electricity usage

So it is about how much electricity is used, not directly about the bill or price.

For cost, Russian would more often use words like:

• стоимость = cost, price
• цена = price
• расходы = expenses, costs

Russian has no articles.

So Russian does not have direct equivalents of:

• a
• an
• the

Whether something is definite or indefinite is usually understood from:

• context
• word order
• the situation
• sometimes added words like этот (this) if needed

So Служба поддержки ответит can mean:

• The support service will reply
• Support will reply
• A support service will reply

depending on context, though in real use it would usually be understood as the support service / customer support.

Yes. Russian word order is more flexible than English word order because cases show grammatical relationships.

The original sentence:

• Служба поддержки ответит вне зависимости от расхода электроэнергии.

is neutral and natural.

But other orders are possible for emphasis, for example:

• Вне зависимости от расхода электроэнергии служба поддержки ответит.

This puts stronger emphasis on regardless of electricity consumption.

Even when the order changes, the meaning usually stays similar because:

• служба is still the subject
• ответит is still the verb
• вне зависимости от still governs the genitive phrase

Yes, usually вне зависимости от sounds a bit more formal, bureaucratic, or written.

Compare:

• вне зависимости от результата = regardless of the result
• независимо от результата = regardless of the result

Both are correct and common, but:

• вне зависимости от often feels more official
• независимо от is often a bit simpler and more straightforward

So this sentence has a slightly formal or institutional tone, which fits well with служба поддержки.

Yes, Russian can move things around more freely than English, but subject + verb is still a very normal default order.

So:

• Служба поддержки ответит ...

is the straightforward, neutral structure: The support service will reply ...

You could also say:

• Ответит служба поддержки ...

but that would sound marked and would usually emphasize who will reply.

In other words:

• Служба поддержки ответит = neutral
• Ответит служба поддержки = more emphatic or contrastive

So the original word order is probably the most natural if there is no special emphasis.

Both words exist, but they are not always used in exactly the same way.

• электричество = electricity, often the everyday word
• электроэнергия = electrical energy / electric power, often more technical or official

In contexts involving:

• utility usage
• meter readings
• tariffs
• consumption figures
• official communication

электроэнергия is very common.

So расход электроэнергии sounds more technical or administrative than расход электричества, though both may be understandable depending on context.
