We've published our Early View of Winter 2024/25 which sets our initial assessment of electricity security of supply for Great Britain the coming winter, and our Winter Review 2023/24 which looks at how conditions impacted demand, margins and balancing costs for the previous winter. 

Learn about how our innovation projects are playing a critical role in exploring new technologies and solutions to deliver a zero-carbon energy system of the future in our Innovation Annual Summary.

If you missed our webinars explaining our new responsibilities as the National Energy System Operator (NESO), you can watch recordings to learn how we can work together to deliver a net zero energy system that balances sustainability with affordability and security.

Ever wonder how much electricity is generated and used in Great Britain?

See Great Britain's electricity generation and how much came from sources such as wind, solar and biomass in our monthly snapshot. 

Our control room experts continue to balance supply and demand second by second and you can follow the electricity mix live in our carbon intensity app – available on Google Play Store and The App Store.
