Interruption Reform

New arrangements for interruption came into effect on 1 October 2011.  Customers are no longer able to elect to be interruptible but must successfully bid for interruption rights through an interruption tender process. The window when offers for interruption can be submitted is normally open in June each year as part of an annual process. The first interruption tender process for the gas year commencing 1 October 2011 was held in June 2008. Additional ad hoc interruption tender events may be held at other times of the year if necessary.
The next opportunity to bid for interruption rights will be an ad hoc event in December 2011. Bids for interruption are invited to be submitted during the ad hoc bidding window which will be open weekdays from 12 to 16 December 2011 inclusive.  A copy of the overall timetable can be found here
