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.


We will approach potential service providers directly if a specific requirement is identified. Intertrip services are required as an automatic control arrangement where generation may be reduced or disconnected following a system fault event.

The requirements for a system to generator operational intertrip service will be determined at the time of setting up a connection agreement

Commercial intertrips may be specified at the time of:

  • a connection agreement being entered into; or
  • negotiation on an ad-hoc basis.

This service can be delivered from any generation connected to the transmission system.
