Lanesborough 110kV Substation Redevelopment Project

This project involves the redevelopment of the Lanesborough Substation which is essential in the movement of energy across the island of Ireland.

This project involves the construction of a new electricity transmission substation on the lands adjacent to the existing Lough Ree Power Station.

Lanesborough 110 kV Substation itself is located in the town of Lanesborough on the boundary of counties Roscommon and Longford. It is situated to the rear of Lough Ree Power Station on a separate site adjacent to the River Shannon.

The substation connects Lough Ree Power Station to the national electricity grid. It also supplies the local distribution network that brings power to homes and businesses throughout Longford and Roscommon. Lanesborough substation dates back to the 1950s. The existing substation uses Air Insulated Technology (AIS), which means the technology is sitting in the outdoors.

Why do we need this project?

Built in the 1950s, Lanesborough Substation is an important point on the national electricity grid. It is essential in the movement of energy across the island of Ireland. Redevelopment of the station is needed for a number of reasons:

  • Equipment in the substation is nearing the end of its life, and is in need of upgrading to ensure a safe and secure supply of electricity for existing customers across Longford and Roscommon and ensure access to secure electricity supplies for new customers.
  • Substations are normally designed with some level of spare capacity to enable important maintenance activities, and facilitate new connections. The substation currently does not allow for this. The proposed new development will meet immediate needs while also providing some reserve capacity.

  • Changes are needed so that the station can accommodate increasing power flows from the west, largely coming from renewable energy.

How will this project help us to reach our sustainable energy targets?

Developing renewable energy is a key part of Ireland’s sustainable energy objectives and climate change strategy. EirGrid’s role as part of this strategy is to facilitate connections for generators, including renewable generators. The EU has set a target for Ireland to generate 40% of our electricity from renewable sources by 2020. Upgrades to the national electricity grid will allow Ireland to take advantage of renewable resources and help us to achieve our goals for climate change.
