Winter Outlook
The Winter Outlook report presents our view of the security of supply for the electricity systems for the winter ahead.
We publish our suite of Outlook publications across the year to provide information and transparency to the industry. We're also increasingly looking to supplement these publications with more continuous engagement through the Operational Transparency Forum.
If you have any comments or suggestions for improvements, please email us.
