Interruption Procedure

When Transco identifies a need to invoke interruption, the following steps are taken:-

Transco informs the Shipper of the need to interrupt

Transco will give a minimum of five hours notice and more if we can - of the need to stop using gas. Wherever possible, the shipper will be given the opportunity to choose which consumers are affected.

Shippers/suppliers contact their Interruptible Consumers

Once the shippers have received notification from Transco, they will, in accordance with their contractual terms, issue notice, to their consumers of the need to interrupt. In exceptional circumstances Transco may contact the consumer directly, for example where there has been a problem with communication, or in a localised emergency.

Shippers confirm with Transco that interruption has taken place

Shippers confirm with Transco, no later than five hours after the interruption notice has been given, that their consumers have interrupted or that they will interrupt, at or before the time required by Transco.

Restoration

As soon as Transco determines that supplies to interruptible consumers can be restored, we will inform shippers of the exact time their consumers can resume taking gas. Shippers will notify the consumers. During periods of interruption, Transco will provide shippers with regularly updated information about the continuing need for interruption this is available via:

• Information Telephone Helpline (recorded message)
• Likelihood to Interrupt Service (available to subscribers)

If consumers require any information about their interruption status, either during or outside a period when their supplies are interrupted, they should contact their shipper/supplier, ring the Transco Information Line or check this Transco website

Note: Gas consumers should always obtain authorisation to re-commence taking gas after interruption from their supplier or shipper.
