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.

In assessing the benefit of acceptance of a commercial intertrip service, the value and costs of that service is considered. For details on the assessment process please see the Commercial Intertrip Service Assessment Principles document.
