SONI Transmission Outage Plan

Transmission Outages

Transmission Outages involve planned times when transmission infrastructure (lines, cables and substations etc.) will be maintained and not in service. It also involves times when testing, connection of new plant and decommissioning of old plant is carried out.

Transmission Outage Programme

We plan and manage an annual Transmission Outage Programme. This programme includes all outages of transmission infrastructure which are planned to occur this year. You can access a list of planned outages for 2024 here. Separate tabs are provided to list outages by region. An ‘Info’ tab is provided to give information on the transmission outage planning process. An updated version of this document will be published in the first week of each month.

See below the weekly documents dealing with the Transmission Outage Programme for 2024.
