Price decrease proposed for Idaho customers

April 02, 2019

BOISE, Idaho — Rocky Mountain Power has proposed a 0.01 percent overall decrease on bills for Idaho customers, resulting from the recent changes in costs of providing energy to customers, together with adjustments stemming from federal tax changes. Typical residential customers using 800 kilowatt-hours per month would see a decrease of about 12 cents on their annual electricity bill.

The annual energy cost adjustment mechanism is designed to track the difference between the company’s actual expenses for fuel and other costs to provide electricity to customers, against the amount being collected from customers through current rates. While these costs were higher in 2018, that amount is more than offset by savings from the 2018 Federal Tax Act. The net bill impact to customers will be a decrease totaling $131,000 for the company’s 82,000 customers in Idaho.

Pending commission approval, the decrease from federal tax changes would take effect effective June 1st, 2019, with the following impact on each rate schedule:

Residential Schedule 1 – 0.01% decrease
Residential Schedule 36 – 0.01% decrease
General Service Schedule 6 – 0.2% decrease
General Service Schedule 9 – 0.01% decrease
Irrigation Service Schedule 10 – 0.01% decrease
Commercial & Industrial Heating Schedule 19 – 0.01% decrease
General Service Schedule 23 – 0.01% decrease
General Service Schedule 35 – 0.01% decrease
Public Street Lighting – 0.01% decrease
Tariff Contract 400 – 0.10% decrease
Tariff Contract 401 – 0.10% decrease

The public will have an opportunity to comment on the proposal during the coming months as the commission studies the company’s request. The commission must approve the proposed changes before they can take effect. A copy of the company’s application is available for public review on the commission’s website, and at the commission offices. Customers may also subscribe to the commission’s RSS feed to receive periodic updates via email. The request also is available at the company’s offices in Rexburg, Preston, Shelley and Montpelier as noted below:
