1. Project Nexus Market Differentiation Formal Market Separation

2. Proposal Formal Separation of Domestic and I&C
Use of Market Sector Code to Define customer type
Simplifies market operation
RBD aligned with Domestic Sector
Aligns with consumers actual market designation
Our current market operation is defined from the unbundling of the Gas Market in tranches and this has led to a disconnect between the actual nature of the consumer and their AQ.
We already hold and flow the Market Sector designation “D=Domestic” “C= Commercial”
The recognition of the existing Market Sector code will simplify market operation for all concerned.
We believe The market sector code is more appropriate as it is truly reflective of the nature of the site.

3. Benefits Reduces existing complexity Reflects Licensing Regime

5. Data Quality Market Sector Code Issue Solution Robustness
Timeline for Nexus allows for Data Cleansing to be undertaken if required
Suppliers free to define approach
It is currently recognised that the Market Sector Code is not a “robust” piece of Data
It is therefore appropriate to consider through the Nexus implementation as the lead times provide ample opportunity for making any changes to Data to ensure its accuracy.
