Central Gas Industry IT System replacement “Project Nexus”

What is Project Nexus?

Xoserve is the Gas Networks’ central service provider and its IT system (“UK Link”) interfaces with Shipper/Supplier IT systems using industry data flows. Xoserve therefore plays a critical function within the gas industry, supporting change of supply processes, meter reading, meter asset information, transportation invoicing, energy balancing and settlement, gas allocations, nominations, and demand forecasting and estimation.

The UK Link IT system was replaced with upgraded technology in June 2017.  This was a very large programme of change for the industry lasting several years.  Project Nexus enabled the technology supporting the gas industry to be updated and meant that read and AQ processes could be improved and a new settlement regime was introduced across the industry.  This enabled the benefit of a smarter market with more granular consumption data to be maximised as the industry rolls out advanced and smart metering.  Project Nexus impacted all gas suppliers (Domestic and Non Domestic) who needed to make changes to their systems and processes to align them with the new central IT system.
