P231 aims to clarify the arrangements and obligations to be undertaken during a Black Start or Fuel Security Code (FSC) event, as currently there is no such detail in the BSC. The P231 solution outlines what is to be considered the duration of a Black Start / FSC event and the processes required to enable normal market operation.


BSC Panel’s recommendation was that the Proposed Modification should be made. The Authority approved the Proposed Modification on 25 June 2009. P231 was implemented on 05 November 2009 as part of the November 2009 Release.
