Section P: Energy Contract Volumes and Metered Volume Reallocations

Section P sets out how Contract Trading Parties (Trading Parties and the NETSO), may notify contract volumes to settlements, specifically to the Energy Contract Volume Aggregation Agent (ECVAA). Two types of notifications, Energy Contract Volume Notifications (ECVNs) and Metered Volume Reallocation Notifications (MVRNs), are allowed and these can only be submitted on behalf of Contract Trading Parties by agents, appointed by the Parties specifically for this purpose, and known as Energy Contract Volume Notification Agents (ECVNAs) and Metered Volume Reallocation Notification Agents (MVRNAs) respectively.

The issues covered in Section P are:

  • how pairs of Contract Trading Parties may authorise ECVNAs or MVRNAs to submit notifications on their behalf, details of the information that such authorisations must contain and the validation checks that the ECVAA applies
  • how such ECVNA and MVRNA authorisations may be terminated
  • the information that ECVNs and MVRNs themselves must contain and the validation checks applied, including Credit Default
  • the process for matching notifications
  • the process through which ECVN’s Volume Data and MVRNs may be nullified
  • the aggregation of the Energy Contract Volume Data and Metered Volume Reallocation Data and the submission of the aggregated data to the Settlement Administration Agent (SAA)
  • how the provisions are modified in the event of failure of the ECVAA systems
