Chris,

I used the Volume from either 521 or 351 to calculate the average price for various charge types.  Look at O:/portland/westdesk/volumemanagement/volmgnt/Jim/EES Monthly/Average Rate Analysis EES.xls

Chris, I can do this for PGES too.  I want to make sure this is what you need in terms of data.  Let me know if you need PGEs.
