Draft Change Proposals (DCPs) for Impact Assessment

DCP0029 - Recommendations of the Unmetered Supplies Expert Group

As part of their 2006 report the Auditor identified a number of ‘Market Issues’ relating to Unmetered Supplies. On ELEXON’s recommendation the SVG agreed that an expert group (UMSEG) should be set up to address these Market Issues.

DCP0029 sets out the solutions proposed by the UMSEG, and has been issued for Impact Assessment to obtain input from the Industry. As part of you impact assessment can you please indicate your level of support for each solution. If there are multiple options, can you please indicate in your response you preferred option.

Change Proposals (CPs) for Impact Assessment

CP1233 – Transfer of the Non Half Hourly Data Aggregator functional requirements from PSL140 to BSCP505 following the creation of PSL100 ‘Generic Non Functional Requirements For Licensed Distribution System Operators And Party Agents’

The CSD review highlighted a large amount of duplication between the requirements in the PSLs and the corresponding BSCPs. To resolve this issue a single generic PSL has been created under CP1182 ‘Creation of a generic Party Service Line’ which will contain participants’ non-functional requirements.

Following on from CP1182, CP1233 was raised on 29 February 2008 by ELEXON and seeks to move the functional requirements of PSL140 ‘Non Half Hourly Data Aggregation’ into BSCP505 ‘Non Half Hourly Data Aggregation for SVA Metering Systems Registered in SMRS’.

CP1233 was previously issued for participant Impact Assessment as DCP0025 via CPC00625 and has since been converted into a CP.

The estimated ELEXON implementation cost for CP1233 is £330. CP1233 is targeted at the November 2008 Release.

CP1234 – Movement of the functional requirements within PSL110 to BSCP514 and BSCP550, following the creation of a generic non functional PSL (PSL100) via CP1182.

As with CP1233, CP1234 was raised on 29 February 2008 by ELEXON following the implementation of CP1182 and seeks to move the functional requirements of PSL110 ‘SVA Meter Operation’ into BSCP514 ‘SVA Meter Operations for Metering Systems Registered in SMRS’ and BSCP550 ‘Shared SVA Meter Arrangement of Half Hourly Import and Export Active Energy’.

The estimated ELEXON implementation cost for CP1234 is £550. CP1234 is targeted at the November 2008 Release.

CP1235 – Movement of Functional Requirements in PSL150 (‘Half Hourly Data Aggregation’) to BSCP503 following the creation of PSL100 for generic non functional requirements.

As with CP1233 and CP1234, CP1235 was raised on 29 February 2008 by ELEXON following the implementation of CP1182 and seeks to move the functional requirements of PSL150 ‘Half Hourly Data Aggregation’ into BSCP503.

The estimated ELEXON implementation cost for CP1235 is £440. CP1235 is targeted at the November 2008 Release.

CP1236 - Clarification of De-Energised and Disconnection Processes - Obligations under BSCP515

The BSC Auditors have reported compliance failures with respect to LDSO’snot meeting the 5 Working Days (WDs) to issue confirmation of a change on energisation status (D0139), an obligation in BSCP515. The reported failures relate to the BSC Auditor’s interpretation that the 5 WDs relates to the time of the request or the proposed date of visit contained within the flow, rather than the actual date of energisation.

CP1236 was raised on 29 February 2008 by ScottishPower and proposes amendments to BSCP515 to provide clarity regarding the issuing of a change of energisation status (D0139 flow) to prevent further differing interpretation of the code.

The estimated ELEXON implementation cost for CP1236 is £110. CP1236 is targeted at the November 2008 Release.

Please carry out an Impact Assessment of the attached DCPs/CPs and return your response using the attached forms by 5:00pm on Thursday 3April 2008. Please let me know as soon as possible if you are unable to meet this deadline. Please note that lack of any response to a CPC does not indicate a negative response.
