Provided documents Phases covered by the IG UCTE Accounting: The Implementation Guide UCTE Accounting cowers the following 3 phases Establishment of Accounting Point Relevant data Matching of Accounting Point Data Issuing of UCTE Settlement results Each of these phases is managed by a different document as following: 1.For the establishment of Accounting Point Relevant data –”Measurement Value Document” (MVD) 2.For the matching of Accounting Point data –”Energy Account Report” (EAR) 3.For issue of UCTE Settlement results –”UCTE Settlement Report” (USR)

Description of 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 10T-Code for tie-lines, (identification of optional additional meter data by local 10Z-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

Meter Measurement Data synchronisation

Meter Measurement Data synchronisation

Establishment of Accounting Point Relevant data Process: The neighbouring TSO agree on the Accounting Point per Tie-Line (Accounting point located in a Substation or on the border) If the accounting point is on the border both TSO have to agree on how to calculated the flow on the border Also they agree on the Meter Measurement Data set be exchanged and validated in the Accounting Point Relevant Data synchronization process Then the TSO exchange the set of Meter Measurement Data by help of the SOMA file. Once both TSO have received a positive Ack. the data are synchronized and provided in file SOVM. SOMA and SOVM files are ”Measurement Value Document” (MVD) documents

Matching of UCTE Accounting Point Data

UCTE Accounting process overview diagram

Matching of UCTE Accounting Point Data Process: Once the SOVM document, containing the synchronized Accounting Point Relevant Data is received, the TSO calculate (consideration of tie-line losses) the Accounting Point Data. As next one of the two TSO prepares the EAR based SOAM document and send it to the neighbour who will release a positive ACK if the Accounting Point Data match with his data. Than the Accounting Point Data are made available on the UCTE Publication Framework (UPF) by both TSO by delivery of the EAR based SOVA document. The final step is the verification of the Accounting Point Data by the concerned UCTE body (Control Area, Control Block and Coordination Centre). There for they download the data from the (UPF) and check if they are consistend.

UCTE Settlement Report

UCTE Settlement Report Process: Once the Accounting Point data are agreed the UCTE Settlement is performed and the results are made available on the UCTE Publication Framework. The UCTE Settlement Process goes from top of UCTE Pyramid to its bottom. As first the Settlement is performed for the coordination Centres and when agreed the calculation for the control blocks is executed. The result are provided to the control blocks by help of the UCTE Publication Framework. Then the control block operator calculates by help of the UCTE Settlement reports, provided by the CC’s, the UCTE Settlement Reports for the Control Area and provide them also by the UCTE Publication Framework. One distinguish between “daily” and “weekly” Settlement Report. Depending on this the content of the UCTE Settlement Report is different.
