METER READING REPLACEMENT MODIFICATION PROPOSAL - UPDATE Stefan Leedham 26 August 2009 © Copyright EDF Energy plc. All rights reserved. PAGE: 5 METER READING REPLACEMENT UNC TPD J 3.7.3: “In respect of the most recent Valid Meter Reading provided to the Transporter in accordance with paragraph 3.4 or 3.5 a User may at any time secure and provide to the Transporter a revised value of such Valid Meter Reading ("Revised Meter Reading"). “ UNC TPD J 3.7.4: “The Transporter will only accept such Revised Meter Reading where the Meter Read Date of such Revised Meter Reading is the same as or later than the Meter Read Date of the most recent Valid Meter Reading recorded by the Transporter.”

METER READING REPLACEMENT MODIFICATION PROPOSAL - UPDATE Stefan Leedham 26 August 2009 © Copyright EDF Energy plc. All rights reserved. PAGE: 6 REPLACEMENT METER READING Based upon the current UNC a replacement meter reading is: Any meter reading taken on a date the same as or later than the most recent meter reading. Therefore the replacement meter reading does not have to be taken on the same date. EDF Energy is looking to maintain the same principle for meter reading replacement but allow the replacement of a meter reading when a subsequent read has been submitted.
