Project Nexus update: new risks to delivery

A new update on Project Nexus, the new settlement system for the gas industry, has identified additional risks to delivery.

The latest programme update highlights that key industry processes such as transfer of ownership may not be operable across industry post go-live, adversely impacting customers. It also identified that:

  • there are risks that participants’ and Xoserve are not aware of, may have misinterpreted or do not adhere to the published baseline of file formats.
  • workarounds and defects post Go-Live  could have an operational impact on shippers and Xoserve.

The update reported “poor progress” on market trials. Test completion run rate “has remained low at 3.4%.”  Only two of 17 parties had began testing in the first week of trials but they reported defects in the system including functionality gaps and lack of data availability. On data, the update reported high defect numbers, tight timelines and complexity of data loads.

Ofgem is already consulting on whether to delay the Go-Live date for the new system, with the most likely scenario a delay of four to six months. A decision is expected at the end of June, after which a replanning will identify a final go-live date.
