1 CVA Long and short Format data files

1.1 CVA Long File Format

The CVA Long Format is essentially a file containing every Line Loss Factor (LLF) for every Settlement Period of every Settlement Day for the BSC Year. The collection of data records is detailed in the table below. LDSOs can choose to create an individual file for each CVA MSID or combine multiple MSIDs into one file.

For example the Settlement Date row would be entered as STD|20090401| in the long format, followed by the LLF row for each Settlement Period of that day. This is then repeated for each Settlement Day.

1.2 CVA Short File Format

The CVA Short Format is essentially a file containing every LLF for every Settlement Period of every Settlement Day for the BSC Year in a grouped format. LLF values are quoted for a range of Settlement Periods, for each Settlement Date, up to the last one in which the value is to be applied.

The collection of data records is detailed in the table below. LDSOs can choose to create an individual file for each CVA MSID or combine multiple MSIDs into one file.
