Laois Kilkenny

EirGrid is proposing to reinforce the network in the general Laois-Kilkenny region. We plan to achieve this through the development of a new transmission line between the two counties.

The proposed infrastructure will consist of the following items:

• A new 400/110 kV substation situated to the south east of Portlaoise, at Coolnabacky. Two existing overhead lines will connect to this new substation. These are the 400 kV Moneypoint-Dunstown line and the 110 kV Carlow-Portlaoise line.
• A new 110/38 kV substation. This will be located next to the existing 38 kV electricity substation at Ballyragget, County Kilkenny.
• A new 110 kV line between the proposed 400/110 kV substation at Coolnabacky and the proposed 110/38 kV substation at Ballyragget.
• An upgrade to the existing Ballyragget - Kilkenny overhead line from 38 kV standard to 110 kV standard. 

We have identified problems that affect quality and security of supply in Kilkenny, Carlow, Kildare and Laois. Existing increases in demand for electricity have caused these problems. Projected growth in demand will further worsen the situation.

To resolve these issues, EirGrid is proposing the Laois-Kilkenny reinforcement scheme as a solution. It follows the transmission planning criteria for the affected areas, and minimises new infrastructure. This will reduce the impact of the scheme.

We have planned for the installation of interim measures in the Kilkenny substation. This will maintain the quality of supply standards to the area, but is only a short-term measure. These interim measures do address the underlying risks to the security and quality of your energy supply.

The Laois-Kilkenny reinforcement scheme will address the concerns on the network in the local area. In particular, it ensures that the system can comply with the grid’s technical standards.

All parts of Ireland need a reliable, high quality standard of electricity supply. This ensures that our electricity network can meet the present and future needs of all users. From homes to farms, and from small businesses to industrial customers.

A strong electricity network provides this reassurance.  This project will enable this region to come up to the national standard of electricity transmission. It will also provide the capacity and security of supply demanded by industry and high tech users. This will allow the region to compete for - and keep - businesses with employment potential.
