Department of the Interior Bureau of Reclamation Regional Office, Regio~ 4 P. O. Box 360 Salt Lake City 10. Ut~h Re: Upper Colorado River Storage Project Tra~8mission Facilities and Power Marketing Dear Mr. Clinton Our company on April 8, 1960 by letter to the Honorable Fred A. Seaton, Secretary of the Interior (copy attached) quoted for wheeling the Project's power, based on the schedule of deliveries furnished by the U.S.B.R. in January 1960. On May 18, 1960 the Secretary announced the Colorado River Storage project marketing area and criteria, approving the use of a trans- mission system as the basis for establishing rate schedules and yard- stick to evaluate proposals for wheeling the power over existing or proposed private utility lines. On September 9 we received a table of estimated distribution of Colorado River Storage Project power and energy, dated August 31, 1960. We find this most recent load schedule at variance with the one that we used to make our April 8, 1960 quote and oUr letter of April 8 makes mention that should there be such variance we desired to re-examine our quotation. Based on the August 31. 1960 schedule lIhich we understand will be used for making comparisons, we wish to quote for estimating purposes the following wheeling charges for de- livery of energy by transmission line to the Phoenix area, plus energy delivered by displacement at Four Corners. (a) Per ki1owatthour for all energy delivered 1.177 mills. This rate is applicable to the total annual energy shown on Exhibit I as a minimum. Energy wheeled above the minimum annual quantity will be at no charge. (b) Alternate - $6.74 per kilowatt year for the yearly peak load as per Exhibit II.
