Idaho Power seeks rate increase

The utility wants ratepayers to cover the cost of reducing emissions.

IDAHO STATE JOURNALAugust 6, 2013 

The company is setting the stage to pass on the cost of enhanced measures on two of four generating units at the Jim Bridger coal-fired power plant near Rock Springs, Wyo.

Idaho Power is asking the Idaho Public Utilities Commission to grant a certificate that would allow it to add the $130 million to its rate base. Idaho Power has one-third ownership in the Wyoming plant, which it calls the “workhorse” of its thermal generating facilities.

Parties who want to intervene in the case to present evidence and cross-examine witnesses include the Idaho Conservation League, the Snake River Alliance and the Industrial Customers of Idaho Power.

Granting the certificate does not immediately affect customer rates but provides a binding commitment from the commission to Idaho Power that the commission will provide rate treatment for amounts up to the company’s commitment estimate.

Idaho Power estimates that the Idaho portion of rates would increase the utility’s annual revenue requirement by about $18.8 million.

The improvements would include the installation of catalytic reduction controls to reduce nitrogen oxide emissions on two of the Bridger generating units.
