Modification Requirements

Energy allocation can be improved in three distinct areas:

• 1. Introduction of three End User Categories for what was EUC01B/EUC02B:
• i. EUC01P/EUC02P – For prepayment heating load
• ii. EUC01I/EUC02I – For Market Sector Code of Industrial & Commercial (I&C) heating load
• iii. EUC01B/EUC02B – All remaining MPRs
• 2. Expand the data items included in the CWV to improve the WCF applied to all EUCs

(including the newly proposed ones) which would require amendments to Section H 5.1.1

• 3. To create wider parameters for the DAF and/or the WCF where the CWV and the SNCWV

are >[1]% tolerance

EUC Splits – Pre-payment Data

• Data supplied as part of RG631 has supported previous analysis that pre-payment customers

had flatter profiles that standard residential customers

• ii. EUC01I/EUC02I – For Market Sector Code of Industrial & Commercial (I&C) heating

load

• iii. EUC01B/EUC02B – All remaining MPRs
• Evidence is clear that there will be benefits from extra EUCs
• DESC is planning the EUC development, BUT will need data

WCF changes

• We have run some analysis on links between UIG volumes and WCF
• UIG is highly correlated to WCF and CWV confirming our view that a large proportion of UIG

is due to the algorithm not flexing sufficiently for temperature movement

• Our analysis shows that UIG is correlated to WCF lag 2 and CWV
• We also ran a number of regressions and the standard parameters of the algorithm are

improved if you also include CWV or SNCWV in addition to the WCF value

• Our belief is we can improve the algorithm by adding an additional two elements – a two day

lag to WCF and an increased weighting on CWV

• HOWEVER we are limited to only our data, which is not pure UIG
• We need help to analyse at an industry level and also to compare to sample data
