Known Gaps in the Data Supplied

as at 12th July 2010


The historical NEM data provided by the AEMO has a small number of instances where data appears to be missing or incorrect. As the AEMO data is downloaded to NEM-Review, these gaps and errors also exist in your local NEM-Review database, and our online web database.

Gaps may be rows missing from the database (when you view the data behind your query you will not see any rows for the missing trading periods), or values of 0 (you'll see a row for the affected trading interval with values of 0 in it).
