The SCTD Transport-Distribution Communication System, is a common, homogenised IT system for all natural gas distributors acting in Spain. It was developed by the Spanish Gas Association (SEDIGAS), and attempts to cover all communication needs between agents, as a consequence of the legal requirements deriving from the liberalisation process on this market.

Nedgia customer managing processes through the SCTD

The SCTD tool can be used for tasks relating to managing the agreement of TPA contracts, consulting data on supply points, meter readings, distribution, programming and nominating, etc.

Development of a common IT application for all natural gas distributors in the Spanish market enables processes to be simplified, communications to be standardised and costs to be reduced for all agents involved.

Processes that can be managed through the SCTD.

Definition

Process for a consumer to switch from being supplied by a certain supply company in the liberalised market to being supplied by a different supply company.

 

Agents involved

  • New supply company (applicant)
  • Outgoing supply company
  • Network owner

 

Application

The new gas supply company requests the change of supplier from the installation owner via the SCTD, using the electronic form established for that purpose, as described in the user manual (A1), attaching a copy of the letter of agreement by the client for the change in supplier.

 

Validation of applications by the installation owner

The installation owner validates the application received, within the legally established deadline. Applications with incorrect data or forms, or corresponding to supply points whose location does not allow any transfer, will be rejected.

 

Response to application

After validation, the installation Owner should inform the gas supply company, within the legally established deadline, whether it accepts or rejects the application for change of supplier, indicating, when relevant, the reasons for rejection, which are defined in the SCTD tables.

The validation or rejection response, and any further correspondence between the gas distributor and supply company, shall be sent using the electronic forms specified in the user manual (A2).

 

Activating the application

If the application is accepted, the installation owner will contact the outgoing supply company with the last reading and the termination date for the TPA contract, and will also activate the new TPA contract after having finalised the switchover process to change to the new supply company. Both communications shall be done using the corresponding electronic messages defined in the user manual (A3).

Definition

Process through which the gas supply company requests the installation owner for amendments to the data affecting the third party network access (TPA) contract, or that needs to be updated on the distributor’s database.

 

Agents involved

  • Supply company with current TPA contract (applicant)
  • Network owner

 

Application

The gas supply company applies for amendment to the Distributor data via the SCTD, using an electronic A1 form set up for that purpose and described in the user manual.

 

Validation of applications by the installation owner

The installation owner validates the application received, within the legally established deadline. Applications with incorrect data or forms, or corresponding to supply points where infeasible amendments are requested, will be rejected.

 

Response to application

After validation, the installation Owner should inform the gas supply company, within the legally established deadline, whether it accepts or rejects the application for change of supplier, indicating, when relevant, the reasons for rejection, which are defined in the SCTD tables.

The validation or rejection response, and any further correspondence between the gas distributor and supply company, shall be sent using the electronic forms specified in the user manual (A2).

Definition

Process for cancelling the TPA contract relating to a supply point on behalf of a supply company.

 

Agents involved

  • Consumer
  • Supply company with current TPA contract (applicant)
  • Network owner

 

Application

The gas supply company should request termination or cancellation of the TPA contract from the installation owner, using the TPA Access Management unit, whether on its own initiative or that of the consumer, in strict compliance with the legally established procedures.

The gas supply company will send the application via the SCTD, using the appropriate electronic file defined in the user manual (A1), attaching a copy of the corresponding regulatory notifications. Furthermore, if the cancellation of the supply contract is initiated by the supply company, it should notify the consumer and the installation owner of the cancellation, by certified mail, or any other medium that reliably guarantees communication. This should take place with at least six working days’ notice, pursuant to legislation.

 

Validation of applications by the installation owner

The installation owner validates the application received, within the legally established deadline. Applications with incorrect data or forms, or corresponding to supply points where infeasible amendments are requested, will be rejected, with the reason for the rejection being specified.

 

Response to application

After validation, the installation Owner should inform the gas supply company, within the legally established deadline, whether it accepts or rejects the application for cancellation of the TPA contract, indicating, where appropriate, the reasons for rejection.

The validation or rejection response shall be sent using the electronic forms specified in the user manual (A2).

 

Activating the application

If the application for cancellation is accepted, the network owner will contact the applicant supply company with the last reading and the termination date for the TPA contract, through the SCTD, using the established electronic forms (A3), and shall proceed to suspend supply to the consumer, as appropriate.

Definition

Process for a gas supply company to annul an application sent previously, for change of supplier or termination of TPA contract, as long as the process has not already been completed.

 

Agents involved

  • Supply company with current TPA contract (applicant)
  • Network owner

 

Application

The supply company should request annulment of a change of supplier or TPA termination process from the installation owner via the SCTD, using the A1 file designed for that purpose (see user manual).

 

Validation of applications by the installation owner

In the same way as for previous cases, the network owner will verify the viability of the application for annulment. If the original process being requested for annulment has already taken place, the application will be rejected.

 

Response to application

After validation, the installation Owner should inform the gas supply company whether it accepts or rejects the application for annulment indicating, where appropriate, the reasons for rejection.

The validation or rejection response shall be sent using the electronic forms specified in the user manual (A2).
