What is Grid Link?

THE Grid Link project, costing €500m, is designed to upgrade and reinforce the electricity transmission network linking Leinster and Munster.
It is part of an overall national electricity network improvement plan that will cost an estimated €3.2bn.
The project is being developed by EirGrid, the State-owned company that operates the national electricity grid.
EirGrid has said it would cost an extra €2bn to install cables underground instead of overhead pylons and power lines.
The original Grid Link proposal now under review by an independent commission would result in the building of 750 high-voltage pylons along a 250km route from Kildare to Cork via Wexford, equivalent to one pylon every 3km.
The proposed pylons would carry 400kV lines and would be much bigger than anything Ireland is currently used to.
The most common type are the 110kV ones on wooden poles. There are 4,122km of these in the country.
In addition, there are 2,000km of 220kV lines.
