Important Changes for Sftp Extracts

IMPORTANT CHANGES FOR SFTP EXTRACTS

This document is prepared to provide information regarding the foreseen changes for SFTP extracts. These changes aim to improve the following points:

• Naming convention of area names within the files, • Naming convention of folder and file names, • Reducing the size of csv files, • Avoiding repeating information within files.

Details of each planned change are provided in the following sections: 1. Naming Convention of Areas

On the existing SFTP files, for some of the area types (for ex: BZN, CTA) TSO names are used for area names. On the other hand, for some other types (for ex: SCA) country codes are used instead of TSO names.

In order to have the same naming convention through all areas, TSO names will be replaced by country codes. When there is more than one TSO for a country, TSO names will be added in addition to country code.

Each area name will have a 3-letter code at the end to specify the area type. (Ex: AT MBA)

All existing area names and foreseen changes are listed in the Appendix B. 2. Naming Convention of Folder & File Names

2.1. Folder Names

Data Item Number will be added to folder names. Existing format will become “DataItemName_DataItemNumber”

Ex: ActualTotalLoad -> ActualTotalLoad_6.1.A

A complete list of changes is available in the Appendix A. 2.2. File Names

In addition to data item number, year & month format will be changed slightly. New format will be “YYYY_MM_DataItemName_DataItemNumber”

Ex: 2020_9_ActualTotalLoad -> 2020_09_ActualTotalLoad_6.1.A

With this change in file names, it will be possible to order files chronologically within the folder in the SFTP directory.

3. Encoding of The CSV Files

Current encoding of UTF-16LE will be changed to UTF-8 encoding. With this change, file sizes will be reduced by ~50%. 4. Eliminating Redundant Columns

In the SFTP extracts, there are some columns with repeating information that can be derivable from other information available. These columns will be eliminated to avoid repetition.

Columns names to be eliminated from the existing CSV extracts are the followings:

• Year • Month • Day

Note: (In/Out)MapCode and (In/Out)AreaTypeCode columns will be eliminated in the long term. 5. Eliminating Files with Repeating Information

For data items 17.1.B & 17.1.C, files that are available per contract type will be eliminated as the same information is available under “AmountOfBalancingReserves" and “PricesOfProcuredBalancingReserves” respectively.

Ex:

Data available under “AmountOfBalancingReserves” files covers all the information from below extracts:

• AmountOfBalancingReservesDaily • AmountOfBalancingReservesHourly • AmountOfBalancingReservesLongTerm • AmountOfBalancingReservesMonthly • AmountOfBalancingReservesWeekly • AmountOfBalancingReservesYearly Therefore, files for per contract-type will be eliminated for the above mentioned 2 data items.
