CP1600 Amend BSCP301 to remove e-mail submission of Funds Accession Form

BSCP 301 ‘Clearing, Invoice and Payment’ requires BSC Parties to submit Trading Charges and bank details to Funds Administration Agents (FAA) through two methods: an online form in Elexon Kinnect and a paper BSCP301 Funds Accession Form. However, the existence of these dual processes has led to data inconsistencies and missing information due to misalignment of mandatory fields, increasing the risk of errors during data entry. Ongoing data anomalies may significantly impact the migration to the new FAA system, which will utilise an API for direct data sourcing, emphasising the need for robust data controls that the current paper process does not support.

CP1599 Remove the requirement in BSCP602 to specify the Half Hourly Data Aggregator in Non-Final Demand Declarations

CP1599 proposes updates to BSCP602 to remove the requirement for Non-Final Demand Declarations to specify the HHDA and Effective From Date (EFD) for each MSID. It also adds a process in the Customer Solution to check if an MSID in the SVA Metering System and Asset Metering System Register has transitioned to the MHHS arrangements and validate and store the relevant MSID information.

CP1594 Creating an Approval Process for New and Legacy Communication Types

Older metering communication types are quickly becoming redundant and are being replaced by newer communication types. Elexon are proposing to create an approvals process to allow for the managed end dating of older technologies, such as Public Switched Telephone Network (PSTN), Circuit Switched Data (CSD) and subsequently 2G.

CP1589 Create Additional Market Participant Role Codes

Market Participant Role Code’ is a single character alphanumeric value which is used as a unique identifier for certain Market Roles. There are 36 possible Role Codes to be allocated to different Market Participant Roles, which are defined in the Market Domain Data (MDD). In order for new Market Roles to be created in the future, a change to the format of the ‘Market Participant Role Code’ Data Item is required to increase the number of available Role Codes. Moving to a two-character alphanumeric value would provide hundreds of new potential Market Participant Role Codes.

CP1588 Mandating Calibration Checks for Main and Check Meters

This CP proposes to provide an assurance process to confirm whether a Meter Type is still operating within the allowed accuracy limits or is drifting towards, or beyond, the extreme end of the limits. It will also define the steps to be taken where an issue is identified mitigating the risk to Settlement. CP1588 originates from Issue 93 ‘Review of the BSC Metering Codes of Practice’.

CP1586 Defining the requirements for Minimum Burden and CT ratios

In some cases, the Current Transformer (CT) ratios for the maximum current of the circuit is not appropriately selected, even though these ratios are vital for accurate energy settlement as they ensure safe and precise current conversion, maintain metering equipment within its optimal operating range, and uphold regulatory compliance standards. CP1586 originates from Issue 93 ‘Review of the BSC Metering Codes of Practice’.

CP1583 Rationalising publication of European Transparency Regulation (ETR) data on Elexon Systems

The ETR data published on the Balancing Mechanism Reporting Service (BMRS) was intended to provide additional insights to the market with approximately 40 reports currently available. This CP identifies several of these reports which are believed to be of minimal  value to Elexon’s customers as the data is duplicated in other reports, has had no data reported, or has been superseded by subsequent regulatory changes.

CP1582 Update BSCP520 on Change of Measurement Class to ensure the UMSO send a D0388 with a zero charge code

CP1582 was originally raised as a housekeeping Change Proposal (CP) to update BSCP520 ‘Unmetered Supplies Registered in SMRS’ step 3.6.2.3, as introduced erroneously by P434 ‘Half Hourly Settlement for UMS Metering Systems’], states “UMSO confirms the de-energisation date to Supplier, NHHDC and MA”’ as Non Half Hourly (NHH) Unmetered Supply (UMS) sites don’t have a Meter Administrator (MA).

Following an objection to the CP as housekeeping, and subsequent consultation period, CP1582 has been expanded to provide greater clarity and alignment with industry process for BSCP520 where a Change of Measurement Class (CoMC) event has occurred.
