         Robert,

Per our conversation 20 minutes ago, I have added two files to
\\csiapapp1a\dataset. These two files are "RESOURCE_INFO.XLS" and
"RESOURCE_INFO.CSV". Both contain the same resource-participant-zone data in
different formats. Please review and let me know if you have questions.

4. Day-Of unconstraint PX energy market clearing prices and quantities

5. Day-Ahead Initial Preferred Schedules, at resource level and aggregated to
participant zonal supply and participant zonal demand leves

6. Day-Of or hourahead initial preferred schedules, at resource level and

7. Day-Ahead energy zonal market clearing prices and quantities

8. Day-Of or hour-ahead zonal market clearing prices and quantities
