Ireland is advancing its energy strategy by expanding partnerships with Spain and the United Kingdom to improve electricity interconnection and strengthen energy security. The initiative focuses on building new infrastructure and reinforcing cross-border grid integration to support a more resilient and sustainable energy system.

A key component of this effort is the proposed Celtic Interconnector, a subsea electricity link between Ireland and Spain, which aims to directly connect the Irish grid to mainland Europe for the first time. In parallel, Ireland is also enhancing its existing and planned interconnections with the UK to ensure stable energy flows and reduce dependency on isolated supply.

These developments are designed to facilitate greater integration of renewable energy, particularly offshore wind, by enabling excess power to be shared across regions. Improved interconnectivity will help balance supply and demand more efficiently while reducing curtailment of renewable generation.

The Irish government emphasized that stronger interconnection is critical for achieving climate targets, lowering energy costs over time, and ensuring long-term energy resilience amid geopolitical and market uncertainties.

By deepening collaboration with neighboring countries, Ireland is positioning itself as a more connected player in Europe’s energy transition—leveraging regional cooperation to accelerate decarbonization and grid stability.
