7 The UCTE Accounting and Settlement process: Provided documents The UCTE Accounting and Settlement process is based on the following documents 1. Measurement Value Document (MVD) used for the verification of Accounting Point Relevant data on meter data level: message types SOMA and (SOVM: only for internal use, no data exchange with neighboring TS0) Identification of Accounting Point Relevant data by official 10T-Code for tie-lines, (identification of optional additional meter data by locally assigned code or local Z-Code for meters) 2. Energy Account Report (EAR) used for the matching of the Accounting Point data on accounting data level: message type SOAM for matching between TSO and SOVA for agreed values for exchange via Publication Framework Identification of Accounting Point data by official 10Z-Code for accounting point 3. UCTE Settlement Report (USR) used for the information of the UCTE Parties about the Settlement results: message types CBSR and CASR Identification of Accounting Point data by official 10Z-Code for accounting point
8 Use of Meter Measurement data in MVD document Identified by an local Code for metersIdentified by an EIC T Code
9 See IG Accounting: Page , line , especially line 460: use of MVD Optional: Local Code for back-up meter Mandatory: 10-T-code best „composition“ of meter data Optional: Local Code for main meter Local Codes in order to identify meters
10 Explanation to page 6 Accounting Point Relevant data shall (must) (mandatory) be exchanged in MVD (10T-Code). These are the meter data, that are necessary in order to calculate the Accounting point, hence accounting point relevant. If for example the meter data of both ends of a tie.line are used for the calculation of the accounting point (e.g. Accounting point is on middle of tie-line or on border point), the meter data of boths ends of the tie-line are accounting relevant data and have to be exchanged.. Each partner is sending in MVD the best “composition” (mandatory with 10-T- Code) of the available meter data from his station (Main meter, back-up meter) (see IG Accounting line ???). In normal cases the best collection of meter data is the pure main meter. In addition to the best “composition” of meter data (mandatory with 10-T-Code) in the MVD the original data from main meter and back-up meter or tele-mesurement etc. (assigned with a local code in the MVD) can (optional) be exchanged in the MVD in order to make transparent, how the best “composition” of meter data was made.
11 Excerpt of IG Accounting Excerpt of IG Accounting: Line 429: In the UCTE process to establish the Accounting Point Relevant data the following rules for identification are to be used: Line 431 · Accounting Point Relevant data are identified with an ENTSO-E assigned EIC "10T„-code. Line 433 · Meter Measurement data are identified with a locally assigned code or an EIC "Z“-code issued by the Local Issuing Office.
12 Abstract MVD and EAR MVD (for SOMA) Accounting Point Relevant data are identified with an ENTSO-E assigned EIC "10T„- code. (Mandatory) Meter Measurement data are identified with a locally assigned code or an EIC "Z„- code issued by the Local Issuing Office. (optional) EAR (for SOAM) Agreed Accounting Point data are identified with an ENTSO-E assigned official EIC "10Z„-code. (Mandatory)

19 Tie-line with 3 ends (2) (split into two lines) TSO A TSO B Local Code Meter C Line 1: 10T-DE-DE-04710H Local Code Meter D MVD: accounting relevant data of point 1 with official 10T-Code „10T-DE-DE-04710H“ accounting relevant data of point 2 with offical 10T-Code „10T-DE-DE-04711F“ accounting data with official 10Z-Code „10Z-DE-DE “ accounting data with offical 10Z-Code „10Z-DE-DE “ Line 2: 10T-DE-DE-04711F EAR: Accounting point 1 Accounting point 2 Note: this is possible, if accounting point 1 is at TSO B and accounting point 2 is at TSO C(!).
