Commissioning of high-voltage installations

For the commissioning of transformation centers and high voltage lines of particular ownership, for their exclusive use, the procedure is the one described for the third group of facilities in Decree 70 / 2010, of 7 of October.

For this, and once the installation has been executed by an installation company qualified in high voltage, according to a project drafted by a competent technician, an inspection will be requested to a control body, and with the inspection certificate with a favorable result, it will be presented the documentation electronically, which must include the Communication form for the presentation of the documentation for the commissioning of high voltage electrical installations (Grupo Tercero), Accompanied by:
- Project drafted and signed by competent qualified technician.
- Summary sheet of features, in excel format.
- Proof of payment of fees.

- Construction management certificate signed by competent qualified technician, according to the established model.
- Declarations of conformity of the manufacturers of the components of the installation that are obliged to do so.
- Facility maintenance contract signed with installation company qualified in high voltage.
- Initial inspection certificate with FAVORABLE result, issued by the Control Body.

In case of any of the cases established in the environmental legislation, the environmental body must also provide a statement on the need to submit the project to any environmental assessment procedure.

The presentation of the Initial Inspection Certificate with a FAVORABLE result, signed by the inspection body, together with the documentation included in Annex III of Decree 70 / 2010, of 7 of October, completed in the Directorate General of Industry, Energy and Mines, enables the licensee to request electricity supply and start the installations provisionally for a period of one month under its responsibility and that of the director of the work, unless there is a pronouncement against it by the competent body.

Administrative silence has estimative effects.

These facilities require administrative authorization for their construction, modification, transfer of ownership or closure of the facility.

To do this, an application for authorization must be submitted, accompanied by the documentation established for the Fifth Group of facilities in Decree 70 / 2010, of 7 in October.

In the case of small power production facilities (nominal power not exceeding 100 kW) connected in low voltage to the distribution network or to the internal network of a consumer, only an operating authorization is required. These facilities can be production with discharge to the distribution network or for self-consumption under the 2 type of self-consumption.

For this, a request for the commissioning certificate must be submitted, along with the documentation established for the Fifth Group of facilities in the 70 / 2010 Decree, of 7 in October.

The facilities under 1 type of self-consumption do not require administrative authorization and must be processed as low-voltage generation facilities according to the provisions of article 18 of the Electrotechnical Regulation for Low Voltage and Order 9344 / 2003, of 1 of October .

Installations built according to standard projects already authorized by the Community of Madrid

For the commissioning of these facilities, the requirements established in the standard projects approved annually by the General Directorate of Industry, Energy and Mines of the Community of Madrid must be followed.

The procedure to be followed is that established for the second group of facilities, which provisionally allows the immediate commissioning, after the presentation of the application and required documentation, for a period of one month, under the responsibility of the owner.

These facilities, which are usually executed by a developer, also require administrative authorization for their construction, and for this, an application must be submitted, accompanied by the documentation established for the Fifth Group of facilities in the 70 / 2010 Decree, of 7 in October.

Once the construction has been authorized and the works have been executed, the application for commissioning accompanied by the assignment contract between the developer and the electricity company must be submitted.

The transfer of ownership of production, transport or distribution facilities requires administrative authorization.
