Outage scheduling

Elia periodically sends updates to contractors and to companies directly connected to the grid to inform them of scheduled outages.

Elia sends out periodic reports about scheduled deactivations or “outages” of grid components (for maintenance work, for example) to companies directly connected to the Elia grid and to contractors who carry out work at its facilities. Reports are only sent to companies directly affected by the outage of a grid component.

Contents

The reports contain information about outage periods, the outage mode, the restitution time for the grid component, information on the safety officer and/or the works manager(s), the type of work planned, and so on.

The first section of the report provides the most up-to-date information, while the second section highlights any changes made to the previous version (the changes are highlighted in the text itself).

Companies receive the initial provisional schedule five weeks prior to the outage. If the schedule changes, an amended provisional schedule is sent out once a week. Changes to the previous version are highlighted.

The final schedule is sent out one week prior to the outage of the grid components. This schedule may, in principle, be updated with the latest available information every day. If necessary, the original version remains valid.
