doing business as Avista Utilities ("Company"), to submit a compliance filing with an updated
Schedule 66 (Temporary Power Cost Adjustment—Idaho) that conforms with the order.

66, which allows the energy charges of electric Schedules 1, 11, 12, 21, 22, 25, 25P, 31, 32, and
41-49 to be decreased by 0.246 cents per kilowatt-hour in all blocks of these rate schedules.

in the updated Schedule 66 is accurate and that the updated schedule complies with Order No.
36339. Staff verified that the rates in the updated schedule 66 reflect the Commission-approved
adjustments for Clearwater and Chelan Hydro expense.
