Market Monitor

Since January 2003 a Weekly Market Monitor report has been published on the Market Surveillance Administrator (MSA) website, at the beginning of each week. As of May 1, 2010, the MSA has ceased publication of the Weekly Market Monitor report. Previous issues of this report have been archived and are available on the MSA’s website at The Alberta Electric System Operator (AESO) now produces a market report, similar to the MSA’s Weekly Market Monitor report, which is published on the AESO website at

The AESO released a public notice advising of errors in the reported Alberta Internal Load (AIL) between November 18, 2009 and March 12, 2010. These errors have since been corrected in the AESO data archives. AIL data errors were carried through to the MSA’s Weekly Market Monitor report for the time period in question. The MSA has not revised the affected reports as the error margin was quite low, however does advise participants to consult the AESO website for corrected AIL information.
