We provide you with a list of your consumption along with its evolution.

In the table on the left, the previous and current readings from your meter performed by the distribution company, along with their corresponding dates, are displayed. The difference between the current reading and the previous reading indicates the consumption (kWh) in the period contained in your bill. This is the same consumption that is displayed in the bill details.

We also inform you if the reading is actual or estimated:

• The actual reading is the value read on the supply meter or metering equipment by the distribution company on the corresponding date.

• The estimated reading is a value calculated by the distribution company, using historical consumption as a basis and according to a regulatory formula established by the Ministry of Industry.

Remember that you have the option of reading your meter yourself, that is to say, you can provide the corresponding distributor with the reading from your meter, either on the Customer Services Telephone Line 900 225 235 or at our Virtual Office for inclusion on your next bill.

You can see that some data is highlighted in blue. These are some of the details that you will need to complete on the "Electricity Bill Simulator" provided by the National Commission for Markets and Competition so that you can check that your bill has been correctly calculated. You can find this simulator at http://facturaluz.cnmc.es.

The graph displayed in this section shows the evolution of your electricity consumption (kWh) over the past 14 months. In this way, you can compare consumption during the last period with the same period the previous year. The highlighted horizontal line marks the average consumption for your contract. When consumption is estimated, the corresponding graphic bar will be displayed with stripes.

We also provide you with data on your average daily consumption for the billed period and for the past 14 months (in euros), along with your accumulated consumption over the past year (kWh).
