Great Britain’s electricity system is one of the oldest, and most complex, in the world.

Every year the ESO moves 300 Terawatt Hours (TWh) of electricity - equivalent to 4 trillion kettles boiling at once – around our system, all whilst enabling the transformation to a sustainable energy system.

We’re experts in all things electricity and we’ve got some of the world’s top engineers working for us to innovate and shape our system of the future.

And we want to share all that knowledge with you.

So if you’re musing about megawatts, or have questions about renewable energy and why we think electric vehicles are such an important part of our future, you’re in the right place.

Learn about some of the hot topics and key challenges facing our industry right here.
