BOISE — Idaho Power customers can expect to see a slightly lower bill this summer.
On June 1, an overall 0.65% rate decrease was implemented, as it was approved by the Public Utilities Commission. The decrease will equal roughly 59 cents for the average residential customer, according to a news release from the Public Utilities Commission.
The decrease is composed of four separate increases and decreases in rates by the company.
Idaho Power rates fluctuate based on a number of tools used by the company.
The Fixed Cost Adjustment is a tool that adjusts costs based on customer energy use over the course of a year. This year, the adjustment increased by 3.64%.
However, another tool used by Idaho Power, the Power Cost Adjustment, decreased by 3.49%.
The Power Cost Adjustment looks at fuel costs and fuel sales and adjusts rates accordingly.
Idaho Power also proposed a slight increase in rates from its closure of the Valmy Power plant in Nevada, which amounted to a 0.11% increase.
The company also proposed a fourth rate adjustment to the Public Utilities Commission, a decrease in the Energy Efficiency Rider. This tool helps pay for varied management programs, according to Idaho Power.
The rate went down from 3.75% to 2.75%, according to the news release.
Altogether, the increases and decreases amounted to an overall decrease in rates from residential customers.
