Due to a failure within the Gemini IS system, ASEP entry capacity was inadvertently and unknowingly resold at Easington for Gas Day 01 March 2007 having been previously allocated within the RMSEC auction. All affected participants were advised yesterday once the matter came to light, and 10 erroneous Day ahead and within day capacity bids were cancelled. National Grid apologises to affected parties and all market participants. The matter received our urgent attention and will continue to do so such that we can better understand the wider impact of this system error, limit the potential for any reoccurrence, and to develop an appropriate and transparent framework for managing any future system or human errors. If you require further operational or commercial assistance please contact either David Mitchell 01926 653438 or Paul Roberts 01926 656369.
For the avoidance of doubt: The affected parties were advised yesterday, this matter has not affected cashout prices or imbalance cashout, and was limited to Gas Day 01 March 2007.
