P428 Report Phase Consultation

Under the current approved P376 solution, VLPs with BM Units that have not been registered as a ‘Baselined BM Unit’ would be required to specify the ‘Inactive’ status of a non-baselined BM Unit. It is Elexon’s view that this new requirement was not intended, is expected to increase both system development costs associated with P376 as well as on-going operational costs for VLPs. This current requirement is not necessary, adds no value and does not better facilitate any of the Applicable BSC Objectives. The Proposer of P376 agrees that allowing non-baselined BM Units would cause a problem and suggested disallowing this functionality.
