Rota Controlled Demand Reduction Outage

Your Electricity supply may be affected in the next 12 hours

Controlled Demand Reduction 

ESB Networks, under direction from EirGrid initiated controlled demand reduction protocols resulting in electricity outages across parts of Ireland.  ESB Networks regrets that some customers are without supply. The emergency actions were required at short notice to protect the integrity of the Irish electricity system as there was insufficient generation available to meet demand.  

  • The Controlled Demand Reduction is expected to run across the different zones for the coming day(s).
  • This disruption will run on a rota basis impacting 1 zone at a time resulting in temporary outages for some customers in the assigned zone. 
  • The maps will display the risk areas within each zone for the specified time period. We apologise to customers who are impacted.

Steps to stay informed

1. Know your Zone

For a controlled demand reduction event there is a map of Ireland which divides the country into three zones (Zone A, Zone B, and Zone C) so that controlled demand reduction is carried out evenly and rotated throughout the entire country

To view the map please click here and zoom in to view your location.

Some areas on the map titled ‘controlled demand reduction zones’ are not colour coded. This means that the electrical network in those areas are not included in plans for controlled demand reduction. These areas are primarily uninhabited areas, or have critical services connected to that part of the network. Please refer to FAQ link at the bottom of this page for further information on ‘How are customers prioritised?
