National Resource Adequacy Assessment Methodology for Ireland and Northern Ireland Consultation

Closed4 Dec, 2023, 11:00 - 26 Jan, 2024, 16:00

Primary tabs

EirGrid has today published a National Resource Adequacy Assessment Methodology for Ireland and Northern Ireland. The methodology document can be found on this page or through the EirGrid website.

EirGrid are looking to the power system of the future and seek to enhance the approach for assessing long term resource adequacy. This methodology outlines the proposed approach. The updated methodology will be used to enhance the existing methodology currently implemented in EirGrid and SONI’s joint publication, the Generation Capacity Statement.

This will be the first of three consultations on the National Resource Adequacy Assessment:

  1. Methodology Consultation – Now open until 12th January
    1. Webinar to be scheduled for Wednesday 13th December
  2. Inputs & Assumptions Consultation – Q1 2024
  3. Final Report Consultation – Q4 2024


EirGrid encourages feedback on the questions posed within the paper. These responses should be submitted through the EirGrid Consultation Portal no later than 16:00 on 12th January 2024.
