  1. AQ Amendment: Relevant UNC obligations and additional Validations Applied 27 May 2010

  2. AQ Amendments: Summary Part 1 • UNC provisions (TPD G1.6.3, G1.6.4 and G1.6.5) Part 2 • xoserve system validations

  3. Part 1: AQ Amendment Window

  4. Part 1: Revised Value Restrictions Larger Supply Points • No restriction Smaller Supply Points • Must be lesser or greater than the Provisional AQ by not less than 20% • Except where the amendment would increase the AQ above 73,200kWh

  5. Part 1: Conditions An AQ Amendment can be raised where: • the User reasonably considers that the Provisional AQ is derived from • incorrect Meter Readings • Meter Readings taken prior to User’s registration • incorrect Supply Meter Installation details • the AQ has been carried forward due the Supply Point being Isolated within year or insufficient Meter Readings

  6. Part 1: User Warranties • When submitting an AQ Amendment, the User warranties: • it has applied a consistent methodology • it has applied a methodology that does not materially differentiate where requested AQs are greater than or less than the Provisional AQ • it has sought amendment of all AQs that it is able to under the UNC when applying the methodology

  7. Part 1: Information Requirements User must specify • MPR • Two Meter Readings (in accordance with TPD H3 – Relevant Metered Period etc) • Relevant Meter Exchange information • Requested AQ User shall record evidence and make available if requested

  8. Part 2: xoserve System Validation • AAI – AQ Amendment requests. • If the Meter Point is not part of any confirmation OR if the Shipper is not responsible for the provided MPRN, it would be rejected with SHI 00010. • If the provided confirmation reference is not the current live confirmation of the MPRN, it would be rejected with MPO 00024. • If smaller supply meter point is not eligible for AQ/WC amendment, then reject with STD 00177 • If an outstanding amendment referral exists for an MPRN, it would be rejected with AQA 00018 • If the requested AQ is less than 1, it would reject with STD 00178 • If the start reading date is less than 01.03.1996, then it would be rejected with STD 00149 • If the end reading date is less than 01.03.1996, then it would be rejected with STD 00150 • If the exchange start reading date is less than 01.03.1996, then it would be rejected with STD 00151 • If the exchange end reading date is less than 01.03.1996, then it would be rejected with STD 00152 • Invalid Imperial Indicator (other than Y/N), rejects with STD 00153 • Invalid Reading Units (other than 1, 10, 100, 1000, 10000), rejects with STD 00155 • Invalid Exchange Reading Units (other than 1, 10, 100, 1000, 10000), rejects with STD 00156 • Invalid Reading factor (other than 0.01, 0.1, 1, 10, 100), rejects with STD 00157 • Invalid Exchange Reading factor (other than 0.01, 0.1, 1, 10, 100), rejects with STD 00158 • Start reading is greater than processing date, reject with STD 00159 • End reading is greater than processing date, reject with STD 00160

  9. Part 2: xoserve System Validation • Exchange Start reading is greater than processing date, reject with STD 00161 • Exchange End reading is greater than processing date, reject with STD 00162 • Invalid Manual check flag (other than Y/N), reject with STD 00163 • Number of dials out of permitted range (ideal range is 4 to 12), reject with STD 00182 • If reading unit, reading factor and imperial indicator are inconsistent, then reject with MMO 00533 • If exchange reading unit, reading factor and imperial indicator are inconsistent, then reject with MMO 00534 • If the end reading is less than start reading, then reject with STD 00166 • If the start reading date is less than the earliest supply point start date, then reject with STD 00183 • If the supply point is end dated and if the end date is greater than the supply point end date, then reject with STD 00183 • If the exchange start reading date must be equal to end reading date, otherwise reject with STD 00164 • If the exchange end reading date is less than or equal to exchange start reading date, otherwise reject with STD 00165 • If exchange TTZ is 0 and if the exchange end reading date is less than exchange start reading date, otherwise reject with STD 00167 • Sum of read TTZ and exchange read TTZ count should not go beyond 99, otherwise reject with STD 00193 • If the shipper is not responsible for the MPRN, it would be rejected with SHI 0010

  10. Part 2: xoserve System Validation • All the readings except the start reading date should be greater than competition effective date, otherwise reject with MRE 471 • If the current and proposed market sector is Domestic, then 20% amendment tolerance rule is applied. Meter AQ changes will be accepted only if it lies beyond the tolerance range with respect to xoserve calculated initial AQ. Reject reason provided is AQA 00019 • The requested AQ value (provided in the file) and the derived AQ (using the parameters in the file) should match, otherwise reject with STD 00179 • If the MPRN is primary and if either the current or proposed market sectors is I&C, then refer the amendment, otherwise reject it with MPO 00587. • If the provided MPRN does not exist on the system, then reject with MPO 00001. • If the start read date is not later than AQ-WC backstop date, then reject with STD 00217 • If the end read date is earlier than xoserve calculated end read date, then reject with STD 00216 • Outstanding AQ/WC Appeal referral exists for this meter point, then reject with AML 00018 • Insufficientinformation to calculate AQ, then reject with AQA 00016 • Consumption period less than 6 month, then reject with MRE 00470 • Post code not found, then reject with POC 00011 • Start reading/date not consistent with UKLink, then reject with RRR 00010 • End reading/date not consistent with UKLink, then reject with RRR 00011 • Exchange start read/date not consistent with UKLink, then reject with RRR 00012 • Exchange end read/date not consistent with UKLink, then reject with RRR 00013

  11. Part 2: xoserve System Validation • TTZ count incorrect, then reject with RRR 00014 • Meter exchange not identified on amendment/appeal, then reject with RRR 00015 • Manual referral with insufficient supporting information, then reject with RRR 00016 • Appeal window not currently open for request, then reject with RRR 00017 • Exchange meter serial number not provided, then reject with STD 00137 • Exchange start reading date not provided, then reject with STD 00143 • Exchange end reading date not provided, then reject with STD 00145 • Occurrence of DM since start reading date, then reject with STD 00171 • Invalid value for number of dials or digits, then reject with STD 00181 • Meter point was not part of a live supply point for entire consumption period, then reject with STD 00183 • DM meter point cannot be appealed/amended to an AQ below the domestic threshold, reject with SPO 00013
