EirGrid Recommendations Paper on LDES Procurement Mechanism

EirGrid has today published a Recommendations Paper on the procurement mechanism of Long Duration Energy Storage (LDES). In the Recommendations Paper, we set out our recommendations on the procurement arrangements for the LDES service. This paper should be read in conjunction with the CRU decision published REF CRU2026174 on 5th November https://www.cru.ie/en-ie/publications/29272/. The recommendations and decision follows a consultation held by EirGrid from 13 October to 24 November 2025. In addition, we are publishing an Afry LCOS Assessment which has been undertaken to help inform the approach to the procurement arrangements.
