© 2007 E.ON12 October 2014, E.ON, Page 3 AQ is a historic calculation and does not reflect changing consumption behaviour of consumers – this was particularly evident over the past 12 months of recession impact on LSP and energy efficiency within SSP  Rolling AQ would help ensure AQ was reflective of changing behaviour as soon as possible  Implementing Rolling AQ would enable benefits in the transition period  A fully AMR/Smart world could also feed into rolling AQ to ensure any estimation was based on current values
