Access and connection to distribution networks is defined by Law 54/1997, of 27 November, on the electricity sector, and Royal Decrees 1955/2000, of 1 December, and 661/2007, of 25 May.

Right to access distribution networks

Líneas aereas

Those eligible to access distribution networks are producers, self-producers, distributors, suppliers, external agents and qualified consumers.

The right of distributors to access the networks of other distributors will be limited to those already in existence and to cases in which it is necessary to increase the interconnection capacity, in order to address the growth in demand in their area and in accordance with minimum cost criteria for the system.

To be able to request access to distribution networks you first need to have a connection point that meets the technical conditions established by law.

This right may only be restricted due to the lack of necessary capacity, in accordance with safety, regularity and quality of supply criteria.

Procedure for connecting to and accessing the distribution network

Agents who wish to directly connect a new installation to the distribution network, or who wish to extend the declared power and conditions of existing installations already connected to the network, need to make their request to the local network distribution manager. This request should include the information required to enable the local network distribution manager to carry out the studies to establish if there is the required capacity.

The evaluation of access capacity and definition of any potential reinforcements will take into account criteria relating to safety and the operation of the local distribution network and the development plans for the network. If there is not sufficient capacity to meet the conditions expressed by the user in accordance with network safety and operational conditions, the local distribution network manager may refuse the request. This refusal must be sufficiently justified and should include suggestions for alternative access through another connection point or, if possible, the reinforcements that need to be carried out on the local distribution network to eliminate the access restrictions.

If a conflict should arise relating to the network connection procedure, the conflict will be put before the competent conflict resolution body (usually the Department of Industry of the Regional Governments).

In cases where a conflict arises relating to the procedure for accessing the network, the conflict will be put before the National Energy Commission.

Access to the distribution network for consumers and generators with an influence on the transport network.

Distribution network managers will forward to the system operator and manager of the transport network all requests for access to the distribution network for new installations that may constitute a significant increase in energy flow in the distribution network’s nodes connecting to the transport network, or which may affect the safety and quality of the service.

Restrictions on use of access to the distribution network

The granting of access gives the user the right to use the network. However, this access may be temporarily restricted to ensure compliance with safety and reliability criteria established to ensure the operation and maintenance of the distribution networks.

Conditions and deadlines for access to the market

  • To have the regulation-compliant meter and Power Circuit Breaker installed.
  • To have signed a contract with a marketing company.
  • If no action is required on the installations:
    • If the billing is bi-monthly, there will be a choice between 15 days after the application or when the reading is taken. Communication takes place with the marketing company directly
    • If the billing is monthly, transfer to the market takes place as appropriate based on the reading cycle
  • If action is required, the transfer takes place when:
    • The action is taken (within the established deadlines, usually 5 days
    • These deadlines apply to the marketing company switch 

Connecting to the distributor’s networks

The point already exists

  • The supply point already exists and a supply is being received (bills are available from the consumer or company) or it exists but has not received a supply for some time.
    • In this case, the consumer must assume the contract from the previous user.
    • If the power is NOT increased, the consumer is NOT required to pay grid access fees because a connection already exists.
    • The consumer is NOT required to pay extension fees because a connection already exists.
    • Take note of the meter reading at the time of entering the property and notify the distribution company.

    Warning: Depending on how long the point has been without a supply, the extension entitlement may have expired (3 years for domestic supplies).

     

    Connection charges:

    These are paid when contracting a new supply or increasing the power for an existing supply. The contract holder pays these fees (usually the consumer)

    Other fees that may be applicable:

    • Supervision charges for transferred installations
    • Connection charges
    • Verification charges
    • Charges for action on measurement and control devices

The point does not exists

  • The supply point does not exist.When connecting a new supply, the connection charges must be paid. This payment covers various items
    • Access to the grid must be requested.
    • The corresponding access and extension charges (1) must be paid and the corresponding connection made

    (1) Extension charges:

    These are paid when requesting new supplies. The applicant pays them (usually the developer).

    Criteria for determining the extension charges

    • Developed land with plot status: the distribution company is required to complete the electrical installation:

    – Low voltage supplies -> Max. Pow. 100kW

    – High voltage supplies -> Max. Pow. 250kW

    • Developed land without plot status: electricity infrastructure cost incurred by the owner.
    • Undeveloped land: electricity infrastructure cost incurred by the owner, including the installations for connection to the existing distribution network and supporting equipment.

     

    Connection charges:

    These are paid when contracting a new supply or increasing the power for an existing supply. The contract holder pays these fees (usually the consumer)

     

    Other fees that may be applicable

    • Supervision charges for transferred installations
    • Connection charges
    • Verification charges
    • Charges for action on measurement and control devices
