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.
CP1595 ‘Correcting the D0148 flow in BSCP520 – CP1590 fix’
CP1595 will remove D0148 from 3.1.12 in BSCP520: Unmetered Supplies Registered in SMRS. The change will ensure references to the Data Transfer Network flows (D0148 in this case) is inputted for its correct use.
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’.
