This project was a joint development between ESB Networks and EirGrid, and is now complete. It was a joint project because it included both a transmission line and a distribution line. (Transmission lines power the national grid, while distribution lines supply electricity to individual customers.)
The new line follows a Y- shaped path. This runs from the south of the county, near Binbane, to a switching station at Glenties. From there the line splits to serve Letterkenny and Derrybeg in the North West of the county. The line is just over 100 km in length, and is carried mainly on pairs of wooden poles. It uses some steel angle masts where the line changes direction.
There was an urgent need to reinforce the electricity network in County Donegal. This is because the demand for electricity in County Donegal had grown significantly over the past fifteen years. There was a risk that the quality of electricity supply would fall below acceptable standards.
We can summarise the problems this project solved as follows:
