Annual Monthly System Entry Capacity Auction (AMSEC) 2008 Tranche 4 Screen Error : Update

NGG would like to update all Users on the issue experienced yesterday (28th February 2008) with the Gemini report screens which show the quantity of entry capacity available in Tranche 4.  Please be advised that we believe this issue has now been resolved for all ASEP’s, apart from a couple of months at Isle of Grain (IG).

When adding a bid the quantities currently shown for capacity available in the Bid Capture screen for Isle of Grain (IG) are incorrect for the periods 1st May 2009 to 31st May 2009 and 1st July 2009 to 31st July 2009. The Capacity & Price Information and the Tranche Details reports are also incorrect for these two months at IG therefore please do not rely upon this information for any assessments made for bidding strategies in Tr 4. The available quantity for May and July 2009 in Tr 4 at IG is 350,440,000kWh/day.

We can confirm that this issue has not affected the Tranche Results reports published on the National Grid website for Tranches 1 to 3.

We apologise for any inconvenience you may have experienced during this time.  Should you wish to contact anyone regarding this issue, the Capacity Team will be available on 01926 654071.
