Whether you’re a balancing provider looking to supply services to us, trying to find the latest Grid Code, or looking for the latest TNUOS charging guidance, you can find all the information you need in our Industry Information hub.

It’s the ESO’s role to make sure there’s enough electricity to keep homes and businesses supplied with the energy they need.

But it’s only by working with our industry partners that we’ll reach our goal of being able to operate a zero carbon electricity system by 2025 and achieve our vision of becoming a trusted partner, to everyone who interacts with us.
