  1. PN UNC Workgroup Settlement Issues 1st November 2011

  2. 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

  3. 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

  4. 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: • Monthly Meter Reading Frequency: 7 calendar days • Annual Meter Reading Frequency: 25 calendar 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 • Currently 14 days, would be 25 days under proposals • Is this acceptable?

  5. 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

  6. 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
