Consumers of electricity have the right to obtain access and be connected to electricity transmission and distribution networks in Spain.
This right is specifically established in Law 24/2013 of 26 December 2013 on the Electricity Sector, and is subject to the fundamental conditions set out in Royal Decree 1047/2013 of 27 December 2013, and in Royal Decree 1048/2013 of 27 October 2013.
It is precisely this connection that permits consumers to be supplied. To be able to achieve this, they must contact the network manager in the area where that physical connection is or will be established
Communication with the distribution company is essential to resolve the issue of enabling a consumer to be connected to the distribution network, or, as the case may be, to the electricity network and all aspects related to it.
Consumers who are not covered by the Voluntary Price for Small Consumers (VPSC) may always choose to contact the distributor directly or, if they already have a supply contract with a supplier, they may also ask that supplier to do so on their behalf. Consumers who have contracted their supply with several suppliers simultaneously must contact the distributor directly.
In any event, all consumers are entitled to a free telephone assistance service provided by the network operator to which their installation is connected. The service operates 24 hours a day, and may be contacted when incidents arise affecting safety or the continuity of supply at the installation. This number must be clearly indicated on the invoices and must be provided to the consumer by the supplier or, where appropriate, by the network operator.
It should be noted that distribution and supply companies are different entities in the electricity sector. In this respect, Law 24/2013 of 26 December on the Electricity Sector, defines them as different subjects in the following way:
In relation to connection, consumers must pay connection charges.
Connection charges will include the following items:
In addition, depending on the case, the consumer must pay for the following items, if they are necessary to execute the activities set out in the definition of said payments:
Lastly, and without prejudice to the above, once connected and as part of the electricity supply, the consumer must pay the respective transmission and distribution tolls and charges.
This will depend on whether the new consumer extends, maintains or reduces the contracted power supply.
If the consumer decides to extend an existing supply, they will be charged for this service extension and this includes paying the distribution company for carrying out all the work necessary to extend the supply. In this case, the cost of the service extension will be based on the power increase to the existing service.
If the consumer decides to reduce the supply or maintain the existing conditions, they only need to pay connection charges
In this case, the consumer must apply to the distribution company for a new connection.
As in the case of extensions to existing connections, this service also includes paying the distribution company for carrying out all the necessary work to set up a new supply.
Likewise, the consumer must pay for the costs of the connection, and for the testing and work on the metering and control equipment.
The above payments are separate from the fees and charges included in the electricity bill once the supply has started
As a general rule, the supply contract, which must be concluded in writing, will be for a period of one year and tacitly renewed for further periods of the same length. However, the consumer and the supplier may freely agree on a period other than one year. A consumer covered by the VPSC may freely switch to the free market and vice versa.
The owner of the electricity supply point concludes a supply contract with a new supplier. The consumer may ask the incoming supplier to implement the switch on a specific date. If they do not do this, it is assumed that the switch must take effect as soon as possible.
The incoming supplier will request the distributor to make the switch (of supplier) within a maximum period of 24 hours (on a working day) from concluding the contract with the consumer.
The distributor will send the incoming supplier notification of the acceptance or rejection.
The incoming supplier may request the distributor to cancel the switch (of supplier). The distributor will assess whether the request is justified and will notify the incoming supplier, as appropriate, of the rejection or acceptance of the cancellation of the switch (of supplier) within a maximum period of five working days from receipt of the cancellation request. If cancellation of the switch is accepted, notification will be sent simultaneously to the incoming supplier, the outgoing supplier and the consumer.
Through the following link you can access the energy offer comparison tool in the free market (for electricity and for gas) designed by the National Commission on Markets and Competition for low voltage consumers, with and without time restrictions:
Market energy offer comparison tool.
For contracts on the regulated market (PVPC), the contracted power must be equal to or less than 10 kW and the consumer must be a natural person or a microenterprise.
A simulation of the PVPC electricity bill (for consumers with contracted power of 10 kW or less) is available on the CNMC (National Commission on Markets and Competition) at the following link:
Before taking any other course of action, consumers wishing to lodge a complaint or claim must contact the customer service department of their supplier or distributor. That department has a period of 15 working days to resolve complaints, claims and any contractual issue raised by its customers. Consumers must first use this channel before they can take any of the options described below.
Suppliers and distributors may introduce an additional customer protection procedure. Any decision made under this procedure will be binding on the company in disputes on the invoicing of contracted services: Customer Ombudsman. This is a free service for customers, which operates independently of the company. The time-limit for reaching a decision will not exceed two months.
In addition, electricity consumers may submit their complaint to the Consumer Arbitration Boards, in accordance with the terms laid down in the applicable legislation.
They may also refer the matter to an accredited alternative dispute resolution entity, the effects, requirements and conditions of which will be set out in the applicable legislation.
Similarly, consumers may contact the autonomous communities and cities of Ceuta and Melilla, which may set up administrative procedures for complaints or disputes arising from supply contracts, network access contracts, or invoicing matters (including the absence of invoicing or related delays in invoicing) where such disputes relate to the supply provided in their respective territories. In addition, consumers who have been refused an energy allowance, or disagree with its application, may lodge a complaint with the relevant customer services.
For electricity supply to be suspended, that possibility must be provided for in the supply or access contract.
As a general rule, the payment period is 20 calendar days from the date of issue of the bill. However, consumers in the free market may agree on a different period with their supply company and have this reflected in their contract.
Without prejudice to the foregoing, the applicable legislation identifies a group of consumers whose supply may not be suspended. These are known as essential supplies. These include the following:
The autonomous communities and local authorities may, within the scope of their competences, declare such supply to be essential.
It must be stated that a declaration of the essential need of a supply point must be demonstrated and notified to the distributor, which will include it in the SIPS.
