Meter number: a unique number that identifies your meter. Each meter has a different code.

Distribution company: the electricity contracted with Iberdrola Clientes is transmitted through the network of the distribution company for your area to the supply point. This company ensures the good state of the installations, connects the supplies to the network and installs and takes the readings from your meter.

Access contract number: a unique number that identifies your contract with the distribution company in case you need to deal directly with it.

Supply point identification (CUPS): Unique Supply Point Code, a number that identifies your supply point with any distribution or marketing company. It's like a national ID number for supply.

Power: this is the maximum amount of energy that can be consumed at a specific time, and it is what allows you to use a set number of household appliances at the same time. It is measured in Kilowatts (kW), and when contracting, its value is set for each hourly period. If your contract does not have a maximeter and you exceed that maximum capacity, the supply will be temporarily cut off. If your contract has a maximeter, the supply will not be cut off, but we will bill you a penalty for exceeding the maximum capacity, as stated in the contract.

Network access toll (ATR): this corresponds to the use made by electricity generating companies and consumers of the distributor's networks. The applicable prices are set by Ministerial Order. In this section we show the toll that corresponds to your supply point. The access toll varies according to the power you have contracted.

Access toll prices: in this section we indicate in which Official State Gazette the current access tariff prices are given.

Duration of contract until: this is the expiry date of your contract. Unless you state otherwise, your contract will be automatically extended. In the event of any price changes in the renewal (because the offer you have now is not in force), we will notify you at least 15 days in advance.

ENERGY

In the Energy section we can have:

Billed power: is the amount you pay to receive the kilowatts (kW) contracted in your supply, regardless of what you have consumed. It is calculated by multiplying the contracted power by the days of the billing period and by the price of the power term.

Billed energy: this is the electrical consumption generated during the billing period, and is measured in kilowatt hours (kWh). Depending on the chosen tariff, you may have a single price for the entire period, or different prices depending on peak/off-peak or at promoted/non-promoted hours. You can see how it has been calculated in the "consumption" section.

Reactive energy: reactive energy is only billed in certain types of contracts, since this energy is generated by some electrical devices that use coils, such as industrial machinery, lifts, pumps, fluorescent lights, etc. It is measured in reactive kilo volt-ampere hour (kVArh) and is only included on the bill if:
Tariffs 2.0 A and 2.1 A: the reactive energy exceeds 50% of the active energy consumption
Tariffs 3.0 A, 3.1 A and 6.x: the reactive energy exceeds 33% of the active energy. It does not apply in the Off-peak period (P3 of tariff 3.X and P6 of 6.X).

Electricity tax: this is a special tax on electricity. According to Special Tax Law 38/1992, it is calculated as follows: Electricity tax = 5.1127% x (Billed consumption + Billed power).
Sometimes more than one line may appear in the billing on the same item. This can happen for two reasons:

• When there has been a change in the prices to be applied in a single billing period
• When different time periods are contracted.

SERVICES AND OTHER ITEMS

Within this section we might have:

Metering equipment rental: the measuring equipment or meter is the device used to measure the energy consumption. It is normally owned by the electricity distribution company in your area and customers have it on a rental basis, so this item will be billed every month by multiplying the number of days in the billing period by the meter rental price, unless the meter is owned by the customer, in which case it is not billed. Its price is established by Law.

Other services: In this section, we will also bill any product or service that you have contracted, such as the Electric Emergency Service, the Household Electric Protection Insurance, or any other item that is not directly related to energy.

The current and previous meter readings are detailed here, as well as the dates on which they were taken. By subtracting the previous reading from the present reading, we arrive at the consumption (kWh) on your bill. We also give the source of the reading (real or estimated).
If you have several contracted periods, we will show you the reading for each period, and if you have a maximeter, we will show you the maximum power for each period.

Only part of the amount of your bill is used to cover the costs of electricity supply. The rest corresponds to a series of taxes and other regulated costs established in current regulations. You can see the breakdown in this graph. Click here if you want to know what each of the items is.

In this space, as on the front, we include useful messages about the amount of your bill or some specific item. You should always read it.

It is a legal requirement to include this information on the bill for customers to know the mix of generation technologies used by Iberdrola Clientes, and their environmental impact

This section will give you some useful tips on how to consume less energy, thus saving on your bill and protecting the environment.
