To ask the Minister of State, Department for Business, Enterprise and Regulatory Reform pursuant to the answer of 15 September 2008, Official Report, column 2128W, on the National Grid: standards, if he will (a) publish the National Grid’s full report and (b) provide an explanation of the third drop in system frequency of 27 May 2008. (224889)

I have been asked to reply.

A full report into the loss of electricity supply is expected to be published before the end of 2008. National Grid is making good progress in establishing the cause of the incident and the consequential effects, and I expect the report to cover each stage of the frequency drop including the third stage.
