NOTICE – Market Concentration Metrics: Additional Stakeholder Feedback

To: Market Participants

Further to our Notice dated December 14, 2006, concerning stakeholder feedback on the MSA’s November 1, 2006 report, we have received additional comments from:

Enmax Corporation

TransAlta Corporation

The MSA is still open to receiving feedback on this issue and its preference remains in receiving that feedback in a written form and that it may make that feedback public. The MSA is still expecting to update the analysis in the market concentration metrics report in the first half of 2007 and will respond to the suggestions of market participants at that time.  If you have comments or questions, feel free to call Mike Nozdryn-Plotnicki               (403) 705 8503         (403) 705 8503 (Email: or Matt Ayres               (403) 705-3182         (403) 705-3182 (Email:
