Connecting the Nation

About us

  • As part of ESB Group, we are licensed to build, operate, maintain and develop the electricity network in the Republic of Ireland.
  • Our countrywide staff of 3,000 people are proud to put every customer first, whatever the electricity supplier.
  • We build and operate the medium and low voltage electricity infrastructure, including distribution stations, overhead lines, poles and underground cables.
  • We are funded through 'use of system' charges billed to customers via Electricity Suppliers, controlled by the Commission for Regulation of Utilities.

Connecting Ireland's Power Network 

At ESB Networks, we've been connecting customers to Ireland's power network for years.  We've also been making new connections, building a network that's stronger than ever so we can all be kinder to the planet. 


Supporting competitive electricity markets

We operate, install, maintain and read meters for our expansive customer base up to four times a year.

Powering the future

We're committed to a lower carbon energy future powered by renewable sources, such as wind farms.

Transmission System

ESB Networks finances builds and maintains the transmission system under a license granted by the CRU and under the direction of Eirgrid. We distribute electricity from the bulk supply to users under the Distribution System Operator License (DSO) granted by the CRU.
