Galway · Limerick · Cork, Ireland

Where could the next cluster emerge?

Western Ireland brings together two signals worth investigating: potential transmission connections and an expanding fibre corridor.

The insight

Power and fibre overlap. That gives land research a direction.

Still to verify

The MW figures are indicative regional potential, with mid-2030s timing and no secured parcel allocation. New transmission-demand resilience rules take effect on 27 October 2026.

Next investigation

Match grid nodes and fibre access to industrial land, then test the connection programme and demand-compliance requirements.

Western 220 kV opportunities come with a mid-2030s timing caution

Potential demand is indicated at 50–100 MW per Galway, Limerick and Cork area on the 220 kV network, or 150–300 MW combined, subject to technical and generation requirements. EirGrid advises assuming new connections from the mid-2030s because station works and outages are already programmed. Capacity is unsecured until a connection contract is executed.

Enet opens western corridor access across Galway, Shannon, Limerick and Cork

The route goes from Ballycoolin through Athlone and Galway, then Shannon and Limerick to Cork. Enet offers duct and dark-fibre access and existing capacity products. Its release separately describes a new ultra-low-latency fibre route as still awaiting commissioning. Aurora publishes a backbone through Galway and a Shannon metro network.

Ireland approves transmission demand resilience rules effective 27 October

The rules cover existing and future transmission-connected demand and address fault ride-through, rate of change of frequency and active-power recovery. The final framework rejects the proposed portfolio approach and uses metering for Demand Utilisation Threshold monitoring. The framework extends the compliance-plan submission period to six months for data-centre derogation applicants; facilities unable to comply are expected to seek derogation before the rules take effect.
