SPA - Supply Point Administration
Shippers can ask Xoserve for details about a site to help them decide whether to nominate or confirm that site before adopting ownership.
This is known as a Shipper Enquiry. You can ask for details such as:
- capacity values
- meter class
- smart meter information.
Enquiries need to be submitted via Xoserve’s Information Exchange (IX) gateway.
Shippers must submit an S47 record (Supply Point Enquiry Request) and an S68 record (Enquiry Supply Meter Point) to enquire about a site.
