Understand your electricity bill once and for all!

Power Consumption Bills 0

Are you one of those who when you look at your electricity bill do not understand half of things? This ends today. We are going to reveal to you the mysterious secret that the concepts that appear detailed in your invoice of the light imply, so that you begin to give a sense to him.

At Lumisa we always preach that knowledge is power, and that to improve something, we must first become aware of what does not work.

At this point, the most relevant data about the invoice are detailed. As they are:

Invoice data
  1. Invoice number.
  2. Date and billing period of the same.
  3. End date of the contract itself.
Supply data

The supply point is the physical place where the meter is located, that is, your house. This section will contain the personal data of the owner, who is the person in charge of the invoices.

The most relevant thing you should know:

  • The CUPS number that is essential for any consultation or management that you wish to carry out.
  • The network access rate is the rate you have contracted, it will depend on whether you have time discrimination or not, and the power band that you have stipulated.
  • Contracted power will be the one chosen in its day with the company based on the needs and within the range of your rate. For example, if you have a 2.0A tariff, it means that your power can range from 0.34 kW to 10 kW. Depending on your usual energy consumption, you can choose one power or another, in an average floor, it is usually around 5 kW. It is important since there are people who have contracted a power well above what they need. We have other articles with tips in which we help you discover it.

Both the invoice number and the contract number are so that we can make arrangements with our marketer with greater agility.

Meter reading

The reading will tell us how much we have spent exactly during the billing period that is specified at the top of the sheet.

As we can see there are different periods: Valle, Punta, Llano, and they will vary depending on whether we have contracted the rate with hourly discrimination (it would be specified as 2.0DHA, 2.1DHA or 3.0A) that divides the periods according to the hours, or without discrimination, which has the same price 24 hours a day.

We know by looking at the concept of access tariff, in this particular case, it is a 2.0A, that is, without time discrimination. Therefore, consumption appears in "Plain". If it were with DHA, it would appear broken down into the different periods according to the rate and the expense that it would have had in each of them.

Below this we have:

  • Current consumption (which is what we have spent since the day we signed up until today).
  • The previous consumption (which is the one that was billed last month or the last invoice you received).
  • It is subtracted between the 2, and the consumption that has been between one and the other is obtained, which will be the one you have to pay. It is in the concept "consumption" in bold so you do not get confused.

Origin of the reading: The reading can be real or estimated.

  • When it is real, it will mean that it is exactly what we have used, not one kW more or one kW less.
  • When it tells us that the reading is estimated, it is because for whatever reason, the distributor has not been able to read our meter, or that we have the digital meter, without having remote management activated.

Therefore, if the reading is estimated, an estimate of the expense is made, calculating the average of the previous invoices. When this happens, we have to send the real reading to our marketer so that we pay what it really is, because otherwise, we may be paying more than necessary. If it were the case, we could check and activate the remote management in our smart meter so that it was sent automatically.

Retail billing

The charge depends on 2 terms: power and energy. The power is as we have explained the one you hire, and you will always be charged, even if you have consumed 0 kW.

That is why it is very important that you have the right one, because if you hire more you will be wasting. We have a couple of articles that talk about it in depth: "Lower the power: yes or no?", "What is the right power for me?".


  • Power term: it is the summary of the power that you have contracted for the days in which the invoice has been generated, the price of the kW.
  • Energy term: The kWh consumed in terms of energy with its corresponding price.

Other concepts:

  • Tax on electricity: it is 5.11% set by the state.
  • VAT: it is 21% and is also set by the state.
  • Measurement equipment rental: if you do not have your own meter, you have to pay your distributor for the measurement equipment rental a small monthly fee.
Consumption history

There is a graph so that you can compare the consumption with your other previous bills.

Payment details

You will see the final amount that is the one that you are going to be charged, and your bank details. Then you view the customer service data, and the number of breakdown services for any problem that may arise.

This information may vary according to the company, there are some where the information is repeated in different ways, or more disaggregated, and several months together, instead of one, but we are committed to clarity and simplicity.

Customer service information

We do not want to deceive you, but that you understand everything in the best possible way, to make sure that you enjoy what is best for you in your particular case.

We hope we have cleared the uncertainty for you.
