Connect a Micro-Generator

Micro-Generator is a source of electrical energy which operates in parallel with ESB Networks LV System and rated up to and including:

  • 25 amperes (6kW) at low voltage [230 volt] when the connection is single phase
  • 16 amperes(11kW) at low voltage [230/400 volt] when the connection is three phase


Note: for connections made after September 2018 some Distribution Code conditions may change, arising from the need to be aligned with European Network Codes. For more information on this see our European Network Codes page.

Micro Generator Solar Panel


The following are examples of different types of Micro-Generators:

  • Wind-power (Turbines)
  • Solar-power (PV panels)
  • Small hydro electric schemes
  • Micro combined heat-and-power (CHP)
  • Combined renewable Micro Generator and storage systems
Note: Standby Generators cannot be used to sell electricity to the electricity grid. If you wish to connect a generator with an output greater than that for micro-generation, go to ​connect a wind farm or other renewable generator.

Step by step guide

To connect a Micro-Generator to the electricity network, you must follow the steps outlined in the document Conditions Governing the Connection and Operation of Micro-generation (PDF | 111 KB). It's useful to read this before you start.


“Note 1: Text in Section 2.2 should now read  “Table 1 below displays the specific Irish Settings” .
Protection settings as per I.S. EN50438:2013 are not acceptable.  New settings were issued in the Oct 2018 edition of Conditions Governing the Connection and Operation of Micro-Generation.


Note 2: I.S. EN50438:2013 has now been withdrawn by CENELEC and replacement standard is now EN 50549-1:2019/AC:2019-04 for which test certificates for inverters should be provided.


Note 3: Certificates to EN50438 but with current protections settings as per Oct 2018 edition of ‘Conditions Governing the Connection and Operation of Micro-Generation’ will continue to be accepted until 30th June 2021”

Do not proceed if you have been notified by ESB Networks (within the specified time-frame) that you cannot proceed with installation of the micro-generator.

It is your responsibility to ensure that the Micro-Generator is installed by a registered electrical contractor to ETCI standards.

The generator (inverter) must comply with EN50438 with Irish settings. We will request a paper copy of the compliance cert and your application will not proceed until compliance is verified.

In order to export surplus electricity for payment, you will need an Import/Export meter.  We will send you a quotation for installing an Import/Export meter.  On completion of the wiring, your Electrical Contractor will submit a validated wiring cert which will be sent to ESB Networks electronically.  

If you do not require an Import/Export meter, please state this on your Application Form.

Installation can start when all of the above conditions have been met.
When the Micro-Generator has been installed and we have received payment for the Import/Export meter along with the necessary ETCI electrical certification, we will install the Import/Export meter.
When the meter has been installed, you can contact your Electricity Supplier regarding payment arrangements for any electricity you export to the grid. You will need to have an agreement with your Electricity Supplier to purchase the electricity exported and to supply the electricity imported. Both import and export must be with the same supplier.
