Summary / Instructions: The MCA Data Base file is the input to the AURORA model used in the Marginal Cost Analysis (MCA). The data base file contains several large tables. Some of this data directly represents assumptions in the MCA while other data represent pointers or other instructions for AURORA.

The AURORA model is owned by EPIS, Inc. and licensed to users. BPA has reached an agreement with EPIS to make the model used in the BPA rate case available to interested parties for $1000. For information on the BPA rate case license contact:

The MicroFin file is an Excel workbook that is used to evaluate the fixed costs of new generation equipment and convert these data in AURORA input format. The essential input data is shown on the 'PROJECT' tab. Use Tools/Scenarios to check various types of generation equipment. To convert the data into AURORA input format, click the "Calcuate AAVs" button on the 'Aurora Calcs' tab. View the AURORA input data on the 'AAV Output' tab.
