Peninsular grid codes

We explain you how to commission a power-generating module connected to the peninsular distribution grid, in accordance with current regulations.

    After the adoption of the Royal Decree 647/2020, of 7 July, regulating aspects necessary for the implementation of the network codes for the connection of certain electrical installations, the Distribution System Operators (DSO) have written the Commissioning Guide for grid-connected power generation modules. 

     

    Which installations does this procedure apply to?

    This procedure applies to Power-Generating Modules (PGMs) with a maximum capacity equal to or greater than 0.8 kW, falling within the scope of Regulation (EU) 2016/631.

    Excluded installations

    The following are excluded:

    • Self-consumption installations without surpluses.
    • Self-consumption installations with surpluses and a capacity equal to or less than 15 kW, located on urbanised land.

     

    How are power-generating modules classified?

    PGMs connected to the Penincular Electricity System are classified according to their capacity and the voltage of the connection point.

    Types of power-generating modules

    • Type A: connection below 110 kV and capacity between 0.8 kW and 100 kW.
    • Type B: connection below 110 kV and capacity above 100 kW and equal to or below 5 MW.
    • Type C: connection below 110 kV and capacity above 5 MW and equal to or below 50 MW.
    • Type D: connection equal to or above 110 kV or capacity above 50 MW.

     

    What steps must you follow for commissioning?

    To commission a PGM, the owner must request several operational notifications from the Distribution System Operator (DSO).

    Types of operational notifications

    • Energisation Operational Notification (EON): allows the internal grid of the module to be energised prior to its commissioning.
    • Interim Operational Notification (ION): allows interim operation and conformity testing.
    • Final Operational Notification (FON): allows definitive operation of the module. To obtain it, you must provide the Final PGM Certificate, in accordance with applicable technical regulations specified in the Technical Rule for the Supervision of Conformity for generators. For those PGM facility owners who should deliver an “MGE Final Certificate” issued by an authorized installer, we provide you with a template.

    Important notice:
    The Limited Operational Notification (LON) was repealed on 2 October 2024.

     

    Procedure by module type

    The commissioning procedure varies depending on the PGM type (A, B, C, or D).
    On the page, you can consult the specific flowcharts for each case.
