Peer Comparison Data
This section displays information relating to Supplier public peer comparison. Details of the public peer comparison process can be found in 
BSCP534 ‘PARMS Techniques’(98Kb)
.
Peer comparison is part of the Performance Assurance Framework. It is a corrective technique and is designed to encourage a Supplier to improve its performance against its peers.
The current set of peer comparison graphs relate to the July 2008 reporting period, and can be downloaded from the tables below.
The next set of peer comparison graphs is for the August 2008 reporting period, and will be published no earlier than 14 October 2008. This allows for 26 Working Days (WDs) after the end of the reporting period plus 5 WDs for any queries. It will be updated monthly with data for the next reporting period.
At its meeting on 21 February 2007, the PAB confirmed its intention to publish graphs for the following Serials:
SP08a – Percentage of Non Half Hourly Energy settled on Annualised Advances at Final
Reconciliation (RF)
- A column graph will show the performance of each Supplier ID based on its percentage
of Non Half Hourly Energy that is settled on Annualised Advances at RF. This data
represents an average of performance across all RF Settlement Runs conducted by
the Supplier Volume Allocation Agent during a calendar month, and is reported per
GSP Group. The required BSC Standard is that a Supplier should settle 97% of its
Non Half Hourly Energy on Annualised Advances by RF. The graphs will show the reporting
period and the range of Settlement dates covered (in the accompanying text), and
Supplier IDs will be shown alphabetically on the x-axis.
- Each graph for Supplier Serial SP08a will display each Supplier ID that operates
in that particular GSP Group for the current reporting period. These will be ordered
alphabetically.
- The percentage (y-axis) scale will be set so as to display the most information
possible for all Supplier IDs.
- There are two horizontal lines labelled for reference. The red line represents the
Industry Standard of 97%, the black line represents the GSP Group average performance
for the reporting period.

format.

SP08b – Percentage of Half Hourly Energy settled on actual Meter readings at the Initial Volume Allocation Run (SF)
-
A column graph will show the performance of each Supplier ID based on its percentage of Half Hourly Energy that is settled on actual Meter readings at SF. This data represents an average of performance across all SF Settlement Runs conducted by the Supplier Volume Allocation Agent during a calendar month, and is reported per GSP Group. The required BSC Standard is that a Supplier should settle 99% of its Half Hourly Energy on actual Meter readings by SF. The graphs will show the reporting period and the range of Settlement dates covered (in the accompanying text), and Supplier IDs will be shown alphabetically on the x-axis.
-
Each graph for Supplier Serial SP08b will display each Supplier ID that operates in that particular GSP Group for the current reporting period. These will be ordered alphabetically.
-
The percentage (y-axis) scale will be set so as to display the most information possible for all Supplier IDs.
-
There are two, horizontal lines, labelled for reference. The red line represents the Industry Standard of 99%, the black line represents the GSP Group average performance for the reporting period.

SP09 – Percentage of Non Half Hourly Metering Systems settled on default Estimated
Annual Consumptions at Third Reconciliation (R3)
- A column graph will show the percentage of the number of its Non Half Hourly Metering
Systems that are settling on default Estimated Annual Consumptions at R3. This data
represents an average of performance across all R3 settlement runs conducted by
the Supplier Volume Allocation Agent during a calendar month, and is reported per
GSP Group for all Supplier IDs with greater than 1,000 Metering Systems. The required
BSC Standard is that no more than 0.1% of Metering Systems should be settled on
default Estimated Annual Consumptions at R3.
- The graphs will show the reporting period and the range of settlement dates covered,
and Supplier IDs will be shown alphabetically on the x-axis.
- The percentage (y-axis) scale will be set so as to display the most information
possible for all Supplier IDs.
- There is a red horizontal line for reference which represents the Industry Standard
of 0.1%.

Commentary for the viewer
The following viewer notes are provided for reference:
- The Standards for Serials SP08a and SP08b do not take into account the size of the Supplier
ID within that GSP Group. This means that small and large Suppliers have to achieve
the same Standard. Therefore, when viewing the graphs it is worth noting that a Supplier
ID may have a low performance but it may only have a low number of Metering Systems,
and therefore a smaller impact on the potential settlement error.
- All Supplier IDs have performance plans in place to improve their NHH performance.
- The performance displayed by these graphs are related to settlement only, and do
not reflect on the Supplier’s ability to produce accurate billing.
The graphs display Supplier IDs. A Supplier ID is a four character reference used
in Supplier Volume Allocation activities. A
Supplier ID(42Kb)
table is available to download for reference and shows which Supplier organisation
is associated with each Supplier ID.
Publication of Peer Comparison data
The intention to publish the above Serials was communicated to the industry via ELEXON Newscast Issue 134(97Kb)
on 26 February 2007. To view Newscast, refer to the Publications section available from the menu on the left hand side of the page.
Refer to the Monitoring and Reporting Peer Comparison section for more information about the function of peer comparison.
The Performance Assurance Board (PAB) will provide a two month notification prior to the publication of any peer comparison data. Current notifications are posted below:
