P441 ‘Creation of Complex Site Classes’

This Modification looks to progress a recommendation of the Issue 88 Workgroup to introduce Complex Site classes. These classes would categorise the types of Complex Site, each having clearly defined criteria within the BSC. A new “type” of Complex Site (referred to as a Class 6 Complex Site) to allow approval of ”non-standard” complex sites would also be introduced.
P441 would also clarify when the netting of Imports from Exports for multiple Metering Systems registered in Supplier Volume Allocation (SVA) is permitted.

This change would facilitate consistency across the market and as so called “Local Energy Schemes” become more popular, rules for when netting are permitted would be clearly defined going forward.
