We are becoming a separate company

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

Black start

Black start is the procedure we use to restore power in the event of a total or partial shutdown of the national electricity transmission system. On this page, you will find out about providing a black start service.

It is possible to provide other balancing services, as long as doing so does not interfere with your ability to deliver black start.

We will consider the provision of a black start service from any provider that can meet the technical requirements of the service.

If you are interested in providing this service to us, please contact us.
