DUDETAILSUMMARY

DUDETAILSUMMARY sets out a single summary unit table so reducing the need for participants to use the various dispatchable unit detail and owner tables to establish generating unit specific details.

DUDETAILSUMMARY is a public table, and is available to all participants.

Source

DUDETAILSUMMARY updates only when registration details change.

New Data Timing

When registration details change

Code Examples

Polars

Casting is enums, categoricals etc is not essential, but may speed up parsing. Swapping int for pl.UInt16, pl.Int32 would also speed up parsing. However some of the datatypes are inferred, so they may be wrong.

This code deduplicates for you. Deduplication is normally only required across multiple months.

This code assumes that all columns are present, which may not be true for older files.

Availability

Visibility: Public

This table is in the public monthly MMSDM archive.

I have collated the list of all those files into one place, in this CSV metadata file. (Columns year, month, url, compressed_size in bytes).

The earliest available data is month 1 of 2015. The most recent available data is month 9 of 2026.

Every month in between has a file. (No gaps.)

Data Size

Each year of data is approximately 5 MB when zipped, 46 MB as unzipped CSV.

Deduplication and PDR Loader Configuration

The primary keys are:

The transaction type is "INSERT-UPDATE", which means that you will likely see duplicate data with different values.

You should deduplicate by sorting based on LASTCHANGED, within each group of primary keys.

PDR Loader configuration is:

Report Name Report Subtype Version
PARTICIPANT_REGISTRATION DUDETAILSUMMARY 6
PARTICIPANT_REGISTRATION DUDETAILSUMMARY 7

This means that the CSV files start with metadata columns:

I,PARTICIPANT_REGISTRATION,DUDETAILSUMMARY,6,...
D,PARTICIPANT_REGISTRATION,DUDETAILSUMMARY,6,...

or

I,PARTICIPANT_REGISTRATION,DUDETAILSUMMARY,7,...
D,PARTICIPANT_REGISTRATION,DUDETAILSUMMARY,7,...

ROW_FILTER_TYPE is LASTCHANGED
