We’ve come a long way from the early 2000s when the nation was mostly powered by coal and gas.

Today, Great Britain has the fastest decarbonising electricity system in the world.

But that’s only because of the work that we have been doing, together with industry partners, to transition to a sustainable future system.

Read the story of how the ESO has decarbonised its electricity system to date, offering a blueprint to other countries around the world to help them reduce emissions. Check out our facts and figures, charting everything from renewable firsts to decarbonisation records.

Carbon intensity dashboard

As the UK closes in on its legally-binding 2050 emissions reduction targets, it’ll be more important than ever to understand how green our electricity is and the impact of any action we, as GB’s Electricity System Operator, take to keep electricity flowing.

We’ve created a dashboard that shows, in real time, the carbon intensity of the system and our balancing actions as well as the current generation mix. It’s an exciting development, providing unprecedented transparency around and insight into our actions – and how close we’re getting to zero carbon operation.
