The System Margins Outlook Report will be published every Monday and Friday, excluding bank holidays. The report will provide market participants with information on the anticipated availability of dispatchable generation capacity to meet peak demand each day over the week ahead; the average and lower confidence renewables forecast; and the availability of the East-West Interconnector and the Moyle Interconnector with Great Britain to support trades - should these be required to meet power system requirements when renewable and dispatchable generation are inadequate.

This sets out the provisional dates for the main milestones for the fifth onshore Renewable Electricity Support Scheme Competition (RESS 5).
