This optional column is used to adjust how the Capacity Pricing Function input works. (That column must reference the Time Series Weekly table, and by default the columns 1-168 represent a reserve margin of 1% through 168%.)  

This column specifies values outside that range by changing the range itself. If the Capacity Pricing Function Offset is non-zero, then its value is added to the column labels to change how the data is interpreted.

For example, if a value of -10 is input in the Capacity Pricing Function Offset column, then columns 1-168 shift to represent reserve margins -9% through 158%.
