List of all BSC Change Proposals
These pages list all Change Proposals (CP) issued since 2001. These are detailed proposals which are raised to amend CSDs and/or BSC Systems, but would not alter the BSC. They must have a clear aim, a single defined solution and contain the relevant redlined documentation changes.
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.
CP1598 Amending the EMDS to add missing Scenario Variants for P375
CP1598 sought to update the Retail Energy Code (REC) Energy Market Data Specification (EMDS), which includes various Market Message Scenario Variants relevant to BSC (Balancing and Settlement Code) processes. BSCP603, introduced for BSC Modification P375, outlined new Scenario Variants of existing Supplier Hub Market Messages to support Asset Metering Virtual Lead Party (AMVLP) processes.
CP1597 ‘BSCP513 Text Change – Bulk Change of Agent’
This CP proposes to remove references to Non Half Hourly Agent roles, and the reference of excluding SVA NHH MOA appointments from BSCP513 to align with Retail Energy Code.
CP1596 Amend BSCP40 to include the process for changes to the Retail Energy Code Energy Market Data Specification
This CP seeks to update BSCP40 to define processes for changing EMDS items.
CP1595 Correcting the D0148 flow in BSCP520 – CP1590 fix
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.
CP1593 New Interconnector Fuel Type Category: Greenlink
Changes are needed to the Insights Solution to ensure data relating to the new Greenlink Interconnector is provided to market participants alongside existing data relating to Settlement arrangements in the Great Britain (GB) electricity market.
CP1592 Upgrade of NHHDA and EAC/AA systems from Oracle 12c to version 19.21
Upgrade NHHDA and EAC/AA systems to the latest available version of Oracle 19.21.
CP1591 New Site Visit Check Code Valid Set value
The implementation of Distribution Connection and Use of System Agreement (DCUSA) Modification DCP411 ‘Charging De-energised sites’ involves updating the J0024 data set by adding a new Enumeration Value.
CP1590 Enabling use of DTN agent appointments process for P434
Enabling suppliers who may be considering the use of DTN derived Dataflows to meet the requirements to migrate their Unmetered Supply (UMS) portfolios over the 12 months up to the UMS mandate go live date.
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’.
CP1587 Obsolete Metering Equipment
Providing a process and transition period to remove unsupported assets and mitigate the risk to Settlement.
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’.
CP1585 Submission of Half Hourly data for Embedded LDSO sites to Host LDSO
This CP proposes that the Half Hourly Data Collector send Half Hourly data for Embedded LDSO connected sites to the Host LDSO via D0275 and/or D0036 to improve the quality of forecasting and reduce manual effort.
CP1584 Allow non-BSC Parties to raise Change Proposals, add a CP withdrawal process and remove BCA/PACA concept
BSC Issue 102 ‘BSC Change Process Review’ identified several improvements to align and simplify BSC Change processes on solution ownership and recommended Elexon make changes to several current processes described within BSC Procedure (BSCP) BSCP40 “Change Management”.
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.
CP1581 Recommendation to update BSCP18 following Issue 105
The Issue 105 ‘Further considerations following implementation of BSC Modification P448′ Workgroup has recommended a number of improvements to BSC Procedure (BSCP) 18 ‘Corrections to Bid-Offer Acceptance Related Data’.
