Change Schedule 3.1 bid and offer validation data

If you are registered as a Scheduled Generator, Semi-Scheduled Generator or Market Participant and need to change your Schedule 3.1 bid and offer validation data, you must complete a Schedule 3.1 notification form. 

You do not need to complete this form if you are registering a new facility, as this information will be requested as part of your application.
