Registrations and modifications


The fees are charged by the Distributor for performing a series of services at the point of supply. These fees will be invoiced by the reseller, and are transferred in their entirety to the Distributor.

Supply entitlements:

They are the amounts payable to the distribution company for the procedures required to handle a new point of supply or to increase the power rating of an existing installation.
Flat rates nationwide. Paid in accordance with the characteristics of the supply. The subscriber connection fees payable are set by the autonomous regions within a margin of ± 5% of the fees established in the ministerial order, although the regions do not always apply this margin.

The subscriber connection fees comprise:

  • Extension fees: Amount payable for the electrical infrastructure required between the existing distribution network and the first element owned by the applicant.
  • Access fees: Amount payable for inclusion in the network.
  • Fees for the supervision of assigned installations: Amount payable for supervision of work and performance of testing and trials prior to commissioning for supply installations opting for direct execution and subsequent assignment of installations.

Look-up, verification and equipment action fees:

  • Hook-up: This comprises the electrical coupling between the receiving installation and the distribution company’s network. In the case of seasonal supplies, the hook-up fees will be reduced up to a fifth of the values indicated if, when the user’s installation once again has voltage applied, it has undergone no modification, and all that is required is the operation of an existing cut-out mechanism.
  • Verification of installations: This refers to the inspection and confirmation that they comply with the regulatory technical and safety conditions. The verification fees will not be charged for increases in power up to the maximum power permissible for the installation as set out in the last installation inspection notice.
  • Actions on metering and control equipment: This comprises the connection and ceiling of the equipment, and any action applied to them by the distributor as a result of decisions by the consumer. The fees for actions on metering and control equipment will initially be the same as those established for the hook-up fees.

* Falls supplies where presentation of an authorised installation agent notice is required, either because it is a new installation or has been subject to a modification, the verification fees will not be charged. If for execution of the installation a project and the final works certificate had to be presented, verification fees will not be payable.

CIE (Electrical Installation Certificate) or BIE (Electrical Installation Notice)

This is an official document issued by an authorised installation agent, certify that the installation has been performed in accordance with the regulations, with the document itself giving the details of the installation.

This document indicates the characteristics of an installation, the power rating and quality.

The CIE (BIE) may be required for various reasons:

  • For the registration of new supplies
  • For an increase in power
  • Because the last CIE (BIE) has expired (duration of 20 years)

Distribution guarantee deposit

According to the terms of Article 79 of Royal Decree 1955/2000, this is the amount to be handed over when the contract is arranged, equal to the theoretical monthly amount to be invoiced corresponding to fifty hours of usage of the power rating.

Official State Gazette 74 of 28/03/2006

The Ministry of Industry and Tourism (Minetur) regulated the standardised power ratings in 2006, and all new contracts must have a power rating aligned with the above table. Those users wishing to increase or reduce their power rating must choose from among the standardised values in the table, wherever the supply is 15 kW less.


Maximeters are fitted to all installations with a power above 15 kW. They measure the maximum power during the different invoicing periods, in intervals of 15 minutes. They may also be fitted for low-voltage tariffs (2.0 or 2.1) provided that they are uninterruptible supplies (such as lifts) or for emergency support (this supplied must be granted as uninterruptible by means of the Distributor and the Ministry of Industry and Tourism).

A reading of the maximeter provides various options for invoicing:

  • If the maximeter reading is below 85% of the contract of power, only 85% of the power will be charged
  • If the readings between 85% and 105% of the contracted power, the power metered will be charged
  • If the maximeter reading is above the contracted power rating, a penalty will be charged


This is the Power Control SWITCH, the function of which is to limit the maximum power contracted for an installation.

The ICP is fitted to the general distribution and protection board of your installation, or integrated within the new meters. As a general rule, the ICP is tripped if the installation demands more power than that contracted.


This is the Universal Point of Supply Code, or the “ID number” of a gas for electricity supply. There can be no identical numbers. It always begins with ES, followed by a series of numbers and two letters designated by the distribution company.

The CUPS must always be included on invoices, and is needed in order to switch to Fenie Energía.


They are used to remunerate distribution, transport and other regulated costs, they are regulated by the CNMC and the Government, the marketers are in charge of collecting it and giving it directly to the area distributors and the corresponding part, to Red Eléctrica.

They are applied to the fixed term (power) and the variable term (consumption).



These periods are approximate* and correspond to a “change of reseller without modifications”. For any other type of contract (news supply, modifications…), the periods will change. To settle any queries you might have, you should contact your Energy Agent.

*The periods may vary depending on the distributor

Types of contract


This is the Voluntary Small-scale Consumer Price, which took effect on 1 April 2014 to replace the former TUR (last-resort tariff). The price of this tariff is set by the Government. The PVPC will be the maximum price that all the Reference resellers may charge.

The PVPC is available to all supplies of a voltage no greater than 1 kV and a contracted power rating below 10 kW (this power rating limit may be modified by the Government).

This contractual mode can only be offered by the CORES (Reference Resellers), since in order to market it a series of requirements established by the Government filled.

The social rebate

This is a Government measure to protect the most vulnerable groups of society. It comprises a discount set by the Government and applied to the PVPC rate.

The only Resellers that can apply the Social Rebate of the COR (Last Resort Resellers).

The Social Rebate is available at:

  • Customers with a contracted power rating below 3 kW (automatically)
  • Pensions receiving minimum benefits (application required)
  • Large families (application required)
  • Households were all members of the family are unemployed (application required)

Types of tariff available for contracting on the open market

Depending on the contracted power rating of the installation and its voltage, supplies will be classified within one tariff or another.
