Summer Outlook report 2021
In our Summer Outlook, we outline Great Britain’s projected electricity needs for the summer ahead.
As the Electricity System Operator, we sit at the heart of Britain’s electricity industry, working in partnership with a wide range of stakeholders to manage the national electricity system and ensure safe, secure and reliable electricity.
The Summer Outlook report helps energy companies with their planning, so they can best provide electricity for the coming months, and we also set out how we will tackle any operational challenges we expect to face.
