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-Generators

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

Step 1 - Familiarise yourself with the process

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.

Step 2 - Make an application

Download Micro Generation Notification form (NC6) | Download PDF 494 KB or call 1850 372 757 or +353 21 2386555 to request a copy.

Email the completed form to NetworkServicesBureau@esb.ie or post it to:

Step 3 - Installation of the Micro-Generator

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.

Step 4 - Installation of Import/Export Meter

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.

Step 5 - Set up export payment arrangements

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.
