​System operator to system operator (SO to SO)

SO to SO services are provided mutually with other transmission system operators connected to Britain's transmission system via interconnectors.

Interconnectors inherently have a range of technical capabilities that enable them to adjust the volume and direction of electricity flows.

Dispatch

How will providers be dispatched?

These services are instructed dynamically following conversation between SO control rooms.

How often will providers be dispatched?

Currently, the need to use SO to SO services is infrequent, at most once a month and sometimes only once or twice a year.
