PN UNC Workgroup
Settlement Issues
1st November 2011
Outstanding Issues
• No outstanding issues for ‘Settlement’ in the issue log,
however
• During an internal review of the BRD a couple of issues
raised around
– Read submission timescales/targets
– Must Reads & Check Reads
• Based on current UNC, the new rules do not provide
more flexibility or protection in some cases
• Following slides detail the current rules as per the BRD
as possible suggestions
• Possible option for all issues is to retain SSP, Smaller &
Larger LSP (e.g. > 293,000 kWh?) within Products 3 & 4

Issue: Read Submission Targets
• Currently in BRD (5.15: Read Submission Performance Targets)
–

–
Product 1 :[99%] of sites in the Shippers portfolio per calendar day
Product 2: [97.5%] of sites in the Shippers portfolio per calendar day
Product 3: [90%] of sites in the Shippers portfolio per calendar month
Product 4: [70%] of sites in the Shippers portfolio per calendar month
• Issue: For Product 3 & 4 there will be a mixture of market sectors
(domestic, Smaller & Larger LSP). Are these % still appropriate?
• Suggest:
– Product 3:
• For SSP [90%] of sites in the Shippers portfolio per calendar month
• For LSP [95%] of sites in the Shippers portfolio per calendar month
– Product 4:
• For Monthly read meters: [90%] of sites in the Shippers portfolio per
calendar month
• For SSP Annual read meters: [90%] of sites in the Shippers portfolio
in a 12 month period
• For LSP Annual read meters: [98%] of sites in the Shippers portfolio
in a 12 month period

Issue: Read Submission Frequency
•
5.8.4: Maximum Read Submission
–
amended in BRD v0.9 – read will be rejected if there has been
a read in the last x days:
•
•
•
Current UNC
–
M3.7.2 Read rejected where more than one Meter Reading is
received by the Transporter;
•
•
•
•
Monthly Read Meter, in any 7 Day period;
Larger Annual Read Meter, in any 14 Day period;
Smaller Annual Read Meter, in any 63 Day period
So for a Larger annual read meter new rules provide
for a lesser max frequency than existing with respect
to a Larger Annual Read Meters
–
•
Monthly Meter Reading Frequency: 7 calendar days
Annual Meter Reading Frequency: 25 calendar days
Currently 14 days, would be 25 days under proposals
Is this acceptable?
4
Issue: Must Reads
• 5.17: Must Reads
–
–
–
–
Product 1: 4 month trigger
Product 2: 4 month trigger
Product 3: 4 month trigger
Product 4:
• where the read frequency is monthly: 4 month trigger
• where the read frequency is annual: 24 month trigger
• Issue: There is likely to be a mixture of market sectors in
Products 3 & 4, so a SSP in Product 3 could receive a
Must Read every 4 months.
• Suggest:
– Product 3 & 4:
• SSP every 24 months
• Smaller LSP every 24 months
• Larger LSP every 4 months
5
Issue: Check Reads
• 5.18: Check Read
–
–
–
–
Product 1: Every 12 months
Product 2: Every 12 months
Product 3: Every 24 months
Product 4: Every 24 months
• Issue: Mixture of market sectors in Products 3 & 4
• Suggest:
– Product 3 & 4:
• Larger LSP every 12 months
• Smaller LSP every 24 months
• SSP every 24 months
