As many of you are aware National Grid is currently developing a new web publication system that will improve the way that market data is presented and accessed on the internet. Previously we have communicated a target date for implementation of 29 October 2007 however ongoing wider system issues have led to the decision to delay the implementation date until the end of November. Notice will be given via the National Grid website before the new implementation date is confirmed and a 2 week parallel run of the new and existing systems is planned as previously.

The data associated with UNC mods 0097a, 0104 and 0121 will continue to be published via the existing web publication system in the interim period.

If you require any further information please contact Paul Gallagher (01926 654109) or Chris Logue (01926 656733).
