SONET is the electricity settlements, DUoS and EMR invoice validation system used by the majority of the large electricity suppliers operating in the GB market. The system handles multiple BSC parties within a single application instance.

Amongst its key features are:

  • Sophisticated data flow scheduler and loader
  • Rigorous data flow validation
  • User configurable validation tolerances
  • Validation of both CVA and SVA volumes by BM unit
  • Validation of NETA settlement charges
  • Validation of DUoS invoices and generation of DUoS remittance advice
  • Validation of GSP Group Take volumes by GSP
  • Validation of BSUoS and TNUoS charges
  • Validation of EMR charges
  • Full audit trail.

On top of its primary validation function, SONET becomes the key source of validated industry data within supply businesses that use it. The data can become core to purchases vs sales analysis, demand forecasting and other commercial areas of the business.

The system uses the Oracle database management system and IBM P-series hardware to efficiently process data that can often approach 2TB in size.

The pivotal role played by the software demands a full breadth support service. St Clements provides a modern professional Helpdesk query and fix service and supplements this with active monitoring of industry change via its Watching Brief service.
