Summary

To facilitate the correct energy balancing / billing and transportation charging (use of a site-specific CV and energy adjustments), SGN requires Xoserve to provide solution options considering impacts on:

  • LDZ System commodity invoice,
  • LDZ Entry invoice,
  • NTS commodity invoice(s)) and,
  • the relevant Shipper’s energy balancing position
  • Capacity charging (incorrect consumptions would lead to incorrect AQs and possibly incorrect SOQs)
  • Impacts of meter reads, reconciliation, ratchets, check-check reads, site visits
  • Adjustments received after D+5 exit close-out

Any acceptable solution option should be considered a pragmatic, tactical solution. Cadent’s Future Billing Methodology (FBM) Project is assessing the possibility to introduce sub-LDZ CV charging zones. It is anticipated a future rollout of FBM will provide a robust and enduring solution that will support the revised biomethane arrangements.
