CEDAR RAPIDS, Iowa – Sept 1, 2011 – Interstate Power and Light Co. (IPL), an Alliant Energy company announced today that it will cycle air conditioners for all participating Iowa customers. Weather conditions are such that from 1-7 p.m. today customers enrolled in the Appliance Cycling Program will have their air conditioner cycled in 15 minute intervals to reduce overall energy usage. Today, Alliant Energy will be sending a signal to the switch for the 48,000 participating customers throughout the state. This cycling event is expected to reduce overall electricity demand by 33 megawatts. 

Participating customers have a small control switch placed on or near their central air conditioner. The control switch will cycle the outdoor cooling unit off and on every 15 minutes. The furnace fan will continue to circulate the cooler, drier air already in the home. Alliant Energy pays each participating customer $8 per month from June through September – whether the air conditioner is cycled or not. A similar program for electric water heaters is also included in today’s event.  Customers enrolled in that program receive a $2 per month discount during the same June through September time period. Appliance Cycling events typically occur between May 15 and September 15 on weekdays from 1-7 p.m. They are not initiated on weekends or holidays. Participation in the program is limited.

This marks a record tenth time Alliant Energy has cycled residential customers this year.
