Generation Consultation 

Along with SONI we have issued a Consultation on NIE Networks Providing Distribution Generation Offers with Non-Firm Market Access for applicants 5MW and above on Friday 20 December 2020.


The consultation runs until the 28 February 2020 with a consultation workshop planned for the week commencing the 27 of January 2020.  

We are inviting interested parties to respond to this consultation. Responses should be sent electronically to and by 4.00pm on Friday 28 February 2020.

Those who wish for their response to remain confidential should highlight this when submitting the response. We may share responses with the Utility Regulator (UR). Respondents should be aware that as the UR is a public body and non-ministerial government department, the UR is required to comply with the Freedom of Information Act.


With network capacity exhausted and the absence of additional energy policy drivers that might permit an economic case to be made by NIE Networks or SONI for future network investment, we have asked for input from industry on a way forward for generation connections through the Call For Evidence issued on the 12 October 2017 and thConsultation on Connecting Further Generation in Northern Ireland (published on 31 January 2018).

Sections 5.2 to 5.4 of the above consultation addressed ‘Distribution Imminent Process Changes and Introduction of Milestones’ which were relevant only to NIE Networks. These sections detailed the changes to queuing principles and presented a number of questions to stakeholders on the potential introduction of milestones to Distribution offer of terms for connection, for a Generating Unit. 

Following the responses received from stakeholders to the consultation and stakeholder input received at the NIE Networks Milestone Workshop held on 20 February, we have now published the Decision Paper on Distribution Generation Process Change and Introduction of Milestones. This paper outlines the responses received from stakeholders in relation to these more immediate matters outlined in Section 5.2 to 5.4 and the rationale for our final decision regarding the milestones which will be introduced into any Distribution offer of terms for connection, of a Generating Unit, issued after the 18 of May 2018.

The updated approach is formalised within the Distribution Generation Application and Offer Process Statement and all applicant’s seeking to connect a Generating Unit, other than microgeneration, should read this Statement for information on the Distribution Generation Application and Offer Process.

The remaining sections of the consultation paper have been addressed through the joint NIE Networks & SONI Consultation Next Steps Paper (published 29 June 2018). The next steps paper proposes the formation of a Connections Innovation Working Group to tackle the complex challenges now faced in order to find solutions that would allow the further connection of generation that are technically and commercially viable for both network operators and generators.

NIE Networks and SONI made a call for expressions of interest from stakeholders to join the working group between 27 July - 17 August. Successful applicants have been notified and the Connections Innovation kickoff meeting is currently being arranged. Please sign up to the mailing list below if you wish to be kept up to date on these matters via e-mail.

Joint Statement regarding Transmission Assessment for Distribution DER Applicants

On the 31 of January 2018, NIE Networks and SONI published a Joint consultation paper on “Connecting Further Generation in Northern Ireland”.  

A “Phase 1 close out report” was included in Appendix 1 of this document which provided a nodal transmission assessment showing nodes with no remaining capacity or potential limited capacity.

This assessment was based on the uptake of all generation within the queue at that time at both Transmission and Distribution Level.  Since this “Phase 1 Close out report” was published, NIE Networks and SONI have both;

  • had connection applications withdrawn
  • issued a number of offers not all of which have been accepted
  • and have received additional connection applications

For the reasons highlighted above the “Phase 1 Close out report” may not reflect the current capacity availability and, potentially, some limited transmission capacity without the need for further transmission reinforcement may still be available at certain nodes within the East of Northern Ireland.
