Powering Up Wicklow

This programme will help deliver a consistent and reliable supply of electricity for Wicklow. 

Powering Up Wicklow requires the installation of a replacement transmission substation in Arklow, adjacent to an existing substation that is approaching end of life.

The existing substation in Arklow is reaching its end of life and needs to be replaced. A Gas Insulated Switchgear (GIS) Substation has been identified as the best solution to address the region’s growing electricity demand. This substation replacement will support: 

• Residential housing and commercial developments 

• Demand growth due to electrification of heat and transport

• Improve security of supply in the Town Centre 

• Bringing renewable energy on to the grid 

EirGrid has surveyed the surrounding area adjacent to the existing Arklow substation to identify suitable sites for this substation replacement to reinforce the electricity grid in Wicklow. 

The location is adjacent to the existing Arklow substation.

Information Events

In 2024 EirGrid held two pop-up information events in Arklow to provide members of the public with information on Powering Up Wicklow and the Arklow Station Redevelopment. 

These events offered an opportunity for interested people and groups to:

• Speak with a member of the technical team and our Community Liaison Officer 

• View details of the project 

• Ask questions or discuss issues which may arise from the project

Our team is always happy to meet with individuals, community, and business groups on a one-to-one basis if requested.
