In planning for a shortage of supply, we have prepared and published a rolling outage plan.

Updating your rolling outage plans

Rolling outage plans must be kept up to date and updated plans must be sent to the system operator for approval. In any event rolling outage plans must be re-submitted to the system operator for approval not later than two years after they were last approved.

Participants who have an approved rolling outage plan should forward their amended plans to the email address After receiving your revised outage plan, we will be in touch to work through the approval process.

The following document provides additional guidance for participants when updating their rolling outage plans:
