Our people

We have one of the most reliable electricity systems in the world and it's all down to our team of incredible people. Read their stories and find out more about how we're building an inclusive and collaborative culture here at National Grid ESO. 

As Great Britain’s electricity system operator, we move electricity around the country to where it’s needed, when it’s needed.

We have a vital role. Think about all the ways in which we use electricity, from charging our appliances, to powering our homes, schools and businesses - we keep Britain running.

It’s thanks to our team of amazing people that we have one of the most reliable electricity systems in the world.

We work with a whole range of experts, including engineers, academics and industry professionals so that we can safely deliver affordable and clean energy to customers.

As we build a greener electricity system of the future, one that can run on zero carbon by 2025, our people know they are shaping the future for generations to come.
