This Change Proposal has been raised to deliver Modification 730.

The Modification was raised to provide relief to customers who have been adversely impacted by Covid-19. As sites have had to cease production as a result of the pandemic, the current arrangements have still meant that capacity charges have been applied. Therefore, where an isolated status has been applied to a Supply Meter Point, partial relief from the capacity charges will be given, without requiring a full Supply Point Withdrawal.

This change aims to apply a discount of 50% to LDZ Capacity Costs for sites that are set as Isolated (utilising the process introduced by UNC Modification 0723 - Use of the Isolation Flag to identify sites with abnormal load reduction during COVID-19 period). The remaining 50% payment is to be seen as a Capacity retention payment guaranteeing the continued availability of capacity at that site. This should be managed through a short-term manual process.

This Change Proposal has been raised to deliver the central changes required as set out within this Modification. At a high level, the CDSP will need to introduce a process to identify the sites which are in scope of Modification 0730 and once these are identified, apply the 50% rebate. If the Modification is approved, it is anticipated that the implementation will be almost immediate and therefore we expect the solution to be predominantly manual.
