Air condition cycling program expands to air base


The Idaho Public Utilities Commission approved an application from Idaho Power Company to expand its air conditioner cycling program to Mountain Home Air Force Base.


During 2007, about 13,600 customers in Idaho Power’s service territory volunteered to participate in the program which allows Idaho Power to cycle residents’ air conditioners from a remote location. Customers receive a $7 per month credit for participating.


Idaho Power asked the commission to approve an agreement it made with the Mountain Home Air Force Base to include the approximate 1,100 residences on the base. Because the base is a single customer with multiple residences, the agreement provides for a cumulative credit on the Air Force base’s September bill at the end of the air conditioning season.


“The commission is pleased with the expansion of the existing program,” the commission’s order says. “We anticipate the base program will be effective in reducing demand during the summer peak periods.”


 The program helps reduce demand on the company’s system during those times when demand is at its peak and electricity is most expensive. That reduced use, in turn, reduces the amount of electricity the company has to buy from the wholesale market or generate from its peaking plants during heavy-use periods, contributing to a smaller Power Cost Adjustment surcharge filed by the company in the spring. Participation in the air conditioner cycling program reduced demand by 10.8 megawatts during last July. One megawatt is enough energy to power roughly 650 homes.
