At the head of the electricity bill
In the highest part, the upper part of the bill, are the data that identifies the company that supplies us with electricity: the logo of your supplier where it is It informs you if the contract we have is a free market or the other case, the regulated one. In the part On the right we find the monthly and bi-monthly consumption periods and, at the bottom, the reference of the supply contract that indicates the installation we have.
Left part of the invoice, are the data of your contract. The customer is informed of the toll rate, which varies depending on the contracted power. Also in this section you will find the power, which ranges between 3.3 and 4.6 kW. In addition, you will be able to check the type of contract made, the reference number of the meter and its class, the start date of the contract and that of the invoice, among other data.
The detail of the general invoice
It is in this part where most lose the desire to continue reading it. Here i knowthey concentrate the taxes payable, the price of the consumption madeand other information that is difficult to fully understand.
The first thing we see is the billing made by the contracted power. There are two broken down concepts: the marketing margin and the toll. To understand the figures, the key is that in both cases the contracted kilowatts are multiplied by the days billed and the daily price.
Next, the billing for energy consumed. In this case, you only pay for what you consume, that is, the company charges you for each kilowatt / hour consumed. Below you will find the charge for the electricity tax -which is 5.113% - and it applies to both consumption and the term of power.
Regarding the rental of measurement equipment - the typical meters - appears in the following place. This cost is given by the Administration and is calculated by multiplying the number of days in the billing period by the price / day of the meter rental, unless the device is yours. Finally, the applicable VAT, which is applied to the total sum of the invoice and which in this supply is 21%.
