We are becoming a separate company

In April 2019, Electricity Transmission is becoming a separate company within the National Grid Group. Find out more about what this change will mean.

Separating the Electricity System Operator (ESO) from Electricity Transmission (ET)

In April 2019, we will legally separate the ESO from the ET function within the National Grid Group.


The Electricity System Operator (ESO) and Electricity Transmission (ET) business separation

Electricity Transmission’s role is adapting to keep pace with an ever-changing system. The business separation is an opportunity for us to keep consumers' household bills down by working to ensure and enable more competition, coordination, and innovation across the transmission network in England and Wales.

While remaining completely focused on delivering energy safely and reliably to those who need it.

What you need to know:

•  the ESO and ET will start operating as separate legal companies within the National Grid Group from April 2019

•  to make sure we get legal separation right, we will be commencing separation activities across the ESO and ET from autumn 2018. This means you’ll start to see the ESO and ET acting as separate entities ahead of the April 2019 go-live date

•  Warwick-based ET employees will be based in a separate part of the building from ESO staff

•  Wokingham-based ESO staff are already physically separate from other employees and will remain in their current location.
