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.

Codes

We administrate four vital codes - the CUSC, Grid Code, SQSS and STC, to ensure the rules which govern the industry’s roles and responsibilities are fit for purpose.

Find out how these codes are changing and how to propose your own modifications to drive improvements.
