A net zero future

Explore how renewables, EVs and more are part of the transition to a zero-carbon system that will take us to net zero 2050.

Great Britain’s electricity system is undergoing an ambitious, exciting and vital transformation. Together with industry, we are creating a cleaner, greener system, one that protects the planet and serves generations to come.

The ESO has a key role to play in tackling climate change by transitioning GB’s electricity system to net zero. We already operate the fastest decarbonising electricity system in the world, with an ambition for zero carbon operation by 2025. And by 2035, we want to run 100% clean, green energy, all the time.

If the UK is to meet its 2025 net zero targets, the electricity industry must play its part.

Our progress towards net zero

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.

Our net zero work

We’re well on our way to net zero, building a network that runs purely on green, clean energy.

But transforming a network isn’t straightforward and to make it happen, we carry out a range of activity that spans multiple time horizons, from real-time all the way out to 2050.

Net zero explained

At National Grid ESO we’re on track to run the grid on zero carbon electricity by 2025.

But what is zero carbon and how is it different from net zero? And how are renewables like wind and solar key to taking us to a greener future?
