Tarbert Redevelopment


EirGrid, a state-owned company, is the national operator of the electricity grid. The national grid is an interconnected network of high voltage power lines and cables, the equivalent of the main roads, dual carriageways and motorways of the road network. EirGrid’s role is to operate, plan and develop the grid to provide customers throughout the country - from rural areas, to homes, business parks, hospitals and sports fields - with a safe, secure, reliable and efficient electricity supply. In particular, development of the grid is essential to provide a platform for renewed economic growth and regional development, and is vital if we are to effectively tap into our abundant renewable resources.

What is Grid25?

Grid25 is a major initiative to put in place a safe, secure and affordable electricity supply throughout Ireland, supporting economic growth and utilising our renewable energy resource to its maximum potential.Grid25 will involve upgrading the high voltage system and an overall investment of approximately 4 billion to the period 2025.This new infrastructure is every bit as essential to the future growth of the country as any investment in road, rail and broadband. Under Grid25, €730 million will be invested in the development of the energy transmission infrastructure for the South-West region.

What is required?

EirGrid has identified a number of areas of the electricity grid in the South West that require reinforcements and one of them is the existing Tarbert electricity substation, located in Tarbert, Co Kerry. The Tarbert substation was built in the 1960s and much of the equipment and structures need to be replaced. Furthermore the location of the Tarbert substation is on a peninsula and any further expansion of the substation at this current location is limited. Relocating to new area in Tarbert will resolve these issues and facilitate future energy developments planned for the region such as the connection of Shannon LNG.

What is proposed for Tarbert?

  • A new electrical substation is required for the Tarbert area.
  • A number of lines currently connected to the station in Tarbert will be diverted to a proposed new substation in the area.
