REQUEST:
Please provide the monthly forward prices that have been quoted to A vista on a daily basis
during the period from January 2002 through March 31 , 2003 for delivery months beginning
March 2003 and ending February 2008.
RESPONSE:
A file entitled "Forward Curves 1-2002 thru 4-2003.xls," is being provided with Avista
data response 4C, and contains CONFIDENTIAL information.
Data Response 4C, contains all forward price curve data for the forward months March 2003
through February 2008 recorded during the period January 2002 through March 31 , 2003. The
data represent an historical record of the Company s "forward curves" for each traded day for
Mid-Columbia electricity. Because broker quote data is available on a monthly basis for only a
few months out, and quarterly data is available for only a few quarters out, the Company
interpolates between available data points using historical market information to create monthly
forward curves.
The worksheet entitled "Sheet 2" contains average 7x24 monthly prices over the period. More
detailed on- and off-peak prices are available in "Sheet I." "Chart I" contains a graphic of the
average March 2003 through February 2008 forward curve price for each trading day beginning
on January 2, 2002 (the first trading day of the year) and ending on March 31 , 2003. The Chart
explains that the lowest average value for the period was recorded on January 7 , 2002 at $23.
per MWh. The highest value, $43.35 per MWh, was recorded on February 25 , 2003. On March
31,2003, the last requested forward curve day, the average price was $35.74 per MWh.
