Winter Outlook

The Winter Outlook Report presents our view of security of supply for the electricity systems for the winter ahead. 

Outlook publications

We publish our suite of Outlook publications across the year to provide information and transparency to the industry. Alongside this, we are increasingly looking to supplement these publications with more continuous engagement via forums such as the Operational Transparency Forum.

If you have any comments or suggestions for improvements, then please email: [email protected].


Winter Outlook 2021 - Early View

We believe this will help to inform the electricity industry and support preparations for the winter ahead.

We will be publishing the next Winter Outlook Report during October 2021.
