Supply Units in SEM

Supplier Units are a collection of demand sites for which metered consumption is aggregated.

There are several distinct types of Supply Units for the purposes of participation:

  • Trading Site Supplier Unit
    Supplier Unit that contains only the demand within a Trading Site and is settled on a net basis against the Generator Units on that Trading Site.
  • Associated Supplier Unit
    A Supplier Unit which is recorded to a Trading Site but may also contain demand outside that Trading Site and has its demand settled on a gross basis with the Generator Unit(s) on that Trading Site.
  • Error Supplier Unit
    Each jurisdiction has an Error Supplier Unit for which loss adjusted net demand in that jurisdiction, allowing for net transfers between jurisdictions, is calculated.
