  1. Single Meter Supply Points Discussion Points for Workstream 0428 27 September 2012

  2. Population of meter points by SPAQ band

  3. Population of meter points by SPAQ band and grouping size

  4. Form of System Capacity Charge

  5. Interesting points to note • SP < 73,200kWh • No interesting points of note!! • All MPRNs keep the same capacity rate aggregated or disaggregated • SP > 73,200kWh and < 293,000kWh • Average increase 18% • Largely due to capacity rate moving “up the step” • Where Supply Points are EUC WAR banded – Meter Point SOQ has been calculated using the same EUC WAR but corresponding with the lower AQ • SP > 293,000kWh and <732,000kWh • Average low (1%) but wide range between -24% and +34% • Largely due to move from a “WAR band” SOQ to EUC bands 1 & 2 • Positives result from moving from High LF EUC bands to lower, default EUC bands - e.g. 42.0% to 31.3% • Negatives result from a counter-positional move • SP > 732,000kWh • Average, across the entire bands – 25% increase • All percentages based on a random sample

  8. Proposed Phased Approach • Immediately – no new configurations • Phase 1: Within 3 months of implementation • All aggregations with AQs up to 73,200kWh to be disaggregated • Accounts for 11.5k supply points or 13% • Phase 2: From 1st April 2014 to 1st July 2014 • All aggregations with AQs above 73,200kWh & up to 732,000kWh to be disaggregated • Accounts for 46k supply points or 53% • Phase 3: From 1st April 2015 to 1st July 2015 • All aggregations with AQs above 732,000kWh to be disaggregated • Accounts for remaining 29k supply points or 36%
