Following on from discussions at the Mod Panel, CER has decided that NQH consumption should be

resettled on a half hourly basis for the time since January 2005 until the SEM arrangements are fully

rather than at rolled up single day and night difference as currently. There is also a requirement for ESB

Networks to provide historical data back to Jan 2005.
