54 MINNESOTA ELECTRIC UTILITY INFORMATION REPORTING - FORECAST SECTION INSTRUCTIONS The individual worksheets in this spreadsheet file correspond closely to the tables in the paper forms received by the utility. The instructions provided with the paper forms also pertain to the data to be entered in each of the worksheets in this file. PLEASE DO NOT CHANGE THE NAME OR ORDER OF ANY OF THE WORKSHEET TABS IN THIS FILE In general, the following scheme is used on each worksheet: Cells shown with a light green background correspond to headings for columns, rows or individual fields. Cells shown with a light yellow background require data to be entered by the utility. Cells shown with a light brown background generally correspond to fields that are calculated from the data entered, or correspond to fields that are informational and not to be modified by the utility. Each worksheet contains a section labeled Comments below the main data entry area. You may enter any comments in that section that may be needed to explain or clarify the data being entered on the worksheet.

Starting the summer of 2013 OTP's resource adequacy obligation is no longer based on its non-coincident peak demand forecast. Therefore, the surplus and deficit capacity values in column 15 do not reflect OTP's capacity position. Starting the summer of 2013 OTP's resource adequacy obligation is based on its load at the time of the Midcontinent Indepent System Operator's (MISO) peak, which occurs during the summer months. Since OTP generally does not peak at the same time as the MISO it's resource obligation is approximately 91% of its summer non-coincident net demand shown in column 7. The net reserve capacity obligation in column 13 was valued at zero because OTP's reserve obligation is based on its MISO coincident
