Initial Project Assessment of the MaresConnect electricity interconnector
We have published a consultation on the Initial Project Assessment of the MaresConnect interconnector.

The CRU proposes to award the MaresConnect interconnector with a Cap and Floor regime in principle. This proposal is in principle as it is subject to a set of Initial Project Assessment (IPA) conditions.
The purpose of this consultation is to seek views on the CRU’s IPA for the MaresConnect interconnector, a proposed 750 MW electricity interconnector connecting Ireland and Great Britain.
We are requesting responses from interested parties, to the questions asked throughout the paper. Please provide supporting evidence-based rationale within responses.
Following the end of the 6-week consultation period, the CRU will review responses received and, taking this feedback into consideration, will commence drafting the decision paper.
Responses should be submitted via the consultation platform by the close of business on Friday, 13th June 2025.
