CP1567 ‘New BSC Procedure (BSCP) for Assurance Information Requests (AIRs)’

The AIR is a Performance Assurance Technique (PAT) which was introduced in May 2022. Currently there is no related BSCP for an AIR, therefore when issuing an AIR, there is no written obligation on Parties to adhere to the request.

This Change Proposal will deliver improvements to the Complex Sites process.

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.

P440 ‘Enabling Elexon to administer the Capacity Market Advisory Group’

The BSC does not currently allow Elexon to undertake administrative activities that would support the Capacity Market Advisory Group (CMAG). This does not align to Ofgem’s decision to appoint Elexon to undertake the CMAG administrative activities on its behalf.

P412 ‘Ensuring non-BM Balancing Services providers pay for non-delivery imbalances at a price that reflects the real-time value of energy’

P430 ‘Extension of P375 to include Suppliers’

P430 seeks to extend the solution to Approved Modification P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point’ to allow Suppliers to register Asset Meters and allocate Asset Metering System Identifier (AMSID) Pairs to Secondary Balancing Mechanism Units (SBMUs).

Read More

P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point’

P375 will allow Metering Equipment situated ‘behind’ the defined Boundary Point to be used for Settlement purposes in place of the Boundary Point Meter. Primarily, this will allow balancing-related services on-site from smaller assets to be separated from current imbalance-related activities, more accurately reflecting the balancing-energy volumes provided by the Balancing Service Provider (BSP).
