P322 proposes new arrangements to migrate sites, classed as Profile Class (PC) 5-8 with Advanced Meters installed, to Half Hourly (HH) Settlement under the P272 obligations. P322 has the following features:

  • Required start and end dates to facilitate a phased approach to implementation
  • Performance Monitoring, most likely through the existing Performance Assurance Framework (PAF)
  • An implementation approach, which considers approved Modification P272 and possible amendment to the P272 Implementation Date by the Authority

The Panel agreed to submit P322 to an Assessment Procedure by a Workgroup, with the Draft Modification Report to be presented to it at its meeting on 11 June 2015.

The P322 Workgroup issued a request for information on 13 May 2015. This initially closed on 20 May 2015, however, the Workgroup welcomed any additional responses by 3 June 2015.
