Idaho Power Files Annual Power Cost Adjustment


BOISE, Idaho—Idaho Power today filed for the annual power cost adjustment (PCA) with the Idaho Public Utilities Commission (IPUC). This filing reflects a true-up of last year's forecasted costs to actual expenses, as well as anticipated fuel costs for generating electricity, power purchases and offsets from the benefit of off-system sales for the coming year. The PCA, an annual filing in place since 1992, is strictly a cost recovery mechanism that passes on both the benefits and costs of supplying energy to Idaho Power customers. It does not contain a profit component.

If approved, today's filing means a rate increase of $93.8 million for the company's Idaho customers, or 11.40 percent overall. For the typical residential customer using 1,050 kilowatt-hours of electricity each month, the monthly increase will be approximately $7.20. The actual percentage of change varies by customer group based upon the rate they pay for electricity.
