EirGrid welcomes signing of MoU to explore potential Ireland–Spain electricity interconnector
The Irish and Spanish Transmission Grid Operators, EirGrid and Red Electrica, have warmly welcomed the signing of a Memorandum of Understanding (MoU) by the Department of Climate, Energy and the Environment and Spain’s Ministry for the Ecological Transition and the Demographic Challenge in Madrid to explore the potential for future electricity interconnection between Ireland and Spain.
The MoU is the first step in assessing the feasibility and benefits of an Ireland-Spain interconnection. It also reflects the close cooperation between transmission system operators, governments, and European partners, working together to explore pathways for future electricity interconnection between the two countries.
The studies to be carried out together will also contribute to the European Commission’s vision for a greater level of interconnection between European countries and regions.
Following the signing of the MoU, Cathal Marley, EirGrid’s CEO said: "The commitment to study the potential for an Irish-Spanish Interconnector is a significant step for the development of our systems and has the potential to play a key role in helping us to move towards greater European energy independence.
"Strengthening Ireland’s interconnection with our neighbours is essential to delivering a secure, low‑carbon energy system and to maximising the benefits of renewable energy for consumers across Ireland and Europe.
EirGrid looks forward to continuing to work closely with colleagues across Red Eléctrica, the Irish Government, and European partners as we collectively advance a cleaner, more secure, and more interconnected energy future.”
Echoing this sentiment, Roberto García Merino, CEO at Redeia added: “Enhanced electricity interconnection is strategically important in supporting the European Union’s objectives for decarbonisation, energy security, and the effective integration of renewable energy sources.
"Redeia looks forward to further engaging with EirGrid, the Spanish Government, and European partners to advance the early-stage feasibility studies in line with the European Union’s interconnection objectives. By connecting our electricity systems, we can support the energy transition and contribute to a more resilient and sustainable power system for Spain, Ireland, and Europe.”
