About the underground cable

The East Meath-North Dublin Grid Upgrade will use High Voltage Alternating Current (HVAC). This form of electricity transmission is used in electricity networks, internationally and in Ireland. Our studies show a 400 kV underground cable between the Woodland and Belcamp substations is the most viable option for this project. The cable will be buried about 1.3 metres below the road surface.

What does underground cable construction look like?

As this project progresses, we will do everything possible to minimise disruption during the construction phase of the project by engaging with local communities, businesses, and landowners.

We will apply to the local authority for permission to install cables. When installing, we will follow our traffic management plan to ensure the least amount of traffic disruption in the area.

The following photos show what construction may look like.
