Connecting Synchronised Generators larger than 6kW single phase or 11kW three phase.
This section explains how to connect generators larger than 6kW single phase or 11kW three phase that may be exporting electricity to the Electricity Network for sale or supply.
This information is generally aimed at developers who wish to construct :
- a single wind turbine larger than 6 or 11kW
- a wind farm
- a landfill gas site
- a combined heat & power (CHP) facility
Note: If you wish to connect a generator less than 6kW single phase or 11kW three phase go to Connect a Micro-Generator.
Group Processing Approach (GPA)
The majority of renewable generator applications are processed under a Group Processing Approach (GPA) which is known as a Gate system. The current Gate is called Gate 3. It is based on a date order queue system that was approved by CER. However, your application may be eligible to be processed outside of the GPA in line with CER direction CER/09/099.

For any other queries not covered on our website, email DSOgenerators@esb.ie.
How to apply
Closure of Gate 3
The applicants for Gate 3 have already been selected and the full list of those included is published in the Gate 3 Node Assignments (PDF | 244 KB). Your application will join the generator applications queue and once all connection offers in Gate 3 have issued, the selection process for the next Gate will be initiated. We will contact you if you are selected for the next Gate. However, your application may be eligible to be processed outside of the GPA in line with CER direction CER\09\099.
For Export Capacity greater than 0.5 Megawatts.
For wind generator applications with an MEC greater than 0.5 Megawatts or other applications that have not been approved to be processed outside of the group process, application will be processed in accordance with the 'Group Processing Approach for Renewable Generator Applications' from CER/05/049.
One year prior to energisation of your project you will be required to submit the NC5 Form (PDF | 737 KB) unless this form has already been completed and the details provided remain unchanged. Any delay in submitting an NC5 form at this stage will delay energisation.
A connection offer will issue to you in due course. This offer will set out the technical and commercial terms including connection charges.
For Export Capacity less than 0.5 Megawatts
ESB Networks will aim to issue connection offers within 90 business days following CER approval (if required) and receipt of the relevant application fee, whichever date is later. The connection charge will be detailed in this offer, which is valid for three months.
Licence to Generate and Supply Electricity
ESB Networks does not issue licences. The CER is responsible for the issuing of authorisations to construct in relation to the construction/re-construction of generating stations, as well as licences for the generation and supply of electricity. For more information go to CER website.
Where a person is proposing to:
- Construct/ re-construct a generating station with an installed capacity not exceeding 1MW;
- Generate electricity from a generating station with an installed capacity not exceeding 1MW,
such a person is not required to apply to the CER in order to receive an Authorisation to Construct/Licence to Generate. This person is deemed to be authorised by Order under Article 5 (1)(b) of S.I. No. 383 of 2008/ licensed by Order under Article 5 (1)(b) of S.I. No. 384 of 2008. Such generators are subject to specific terms and conditions as set out in the relevant Orders. For more information go to CER website.
