TWIN FALLS, Idaho (KLIX)- Idaho Power customer’s may see an increase in their monthly power bills if Idaho state officials allow it. Idaho Power said the company filed its annual Fixed Cost Adjustment with the Idaho Public Utilities Commission. Average residential customers would see and extra $2.16 on their monthly bills. Overall the company says the increase would be about $11.2 million between residential and small general service customers.

If approved by the IPUC,  customers would see the change beginning June 1st of this year. Idaho Power says it is asking for the fixed cost adjustment because of successful energy conservation by customers. However, the company says the costs for its power plants, power lines, substations and some administrative cost still exist, thus the need for a rate hike to make up lost revenue.
