Customer Change Team Leader


This change seeks to create a new charge [SoLR customer charge], through which the Gas Distribution Networks (DNOs) will recover any LRSP arising from a SoLR event.

It is proposed that the SoLR customer charge is introduced into the Gas Transportation charging statements. This new charge will be split by domestic and non-domestic Charging Codes and will be calculated by each DNO.

The charge, which will be on a Supply Meter Point basis and will be calculated to recover the costs originating from each market sector, with mixed portfolios allocated by market sector code as held within UK Link (domestic or I&C).
