Process to put into service new power-generating modules

What procedure must you follow to commission an electricity generation module connected to the distribution network in non-peninsular electricity systems, who it applies to, and what notifications are required under current regulations.?

    1. Regulatory framework

    This procedure is based on Royal Decree 647/2020 of 7 July 2020, which regulates the application of network connection codes for certain electrical installations.

    Based on this standard, Distribution Network Operators (DNOs) have defined a specific commissioning guide for generation modules connected to non-peninsular networks.

    2. Who does this procedure apply to?

    This procedure applies to new Electricity Generation Modules (EGMs) in the Non-Peninsular Electricity System, except in the following cases:

    • Self-consumption installations without surpluses.
    • Self-consumption installations with surpluses and a capacity equal to or less than 15 kW, provided that:
      • They are located on urbanised land.
      • They have the amenities and services required by urban planning regulations.

    3. What procedure must you follow?

    If you are the owner of an Electricity Generation Module, you must request a series of operational notifications, as defined in Regulation (EU) 2016/631, from the Distribution Network Operator.

    These notifications allow the module to be connected to the grid and begin operating in a progressive and controlled manner.

    4. Types of operational notifications

    Notification

    What it allows

    When it is issued

    EON – Not

    Authorises the energisation of the module's internal network

    Before energising the installation

    ION

    Allows temporary operation and the start of compliance testing

    During a limited period

    FON

    Authorises the final operation of the grid-connected module

    After passing the tests and submitting the documentation

    LON

    Repealed since 02/10/2024

    Not applicable

     

    To obtain the Final Operational Notification (FON), you must provide the Final EGM Certificate, in accordance with the Technical Standard for Conformity Supervision for generators in non-peninsular systems.
