On February 10, 2009, the Idaho Department of Environmental Quality issued the final air permit for the Power County Advanced Energy Center to Southeast Idaho Energy LLC (SEI). SEI is a wholly owned subsidiary of Refined Energy Holdings LLC. SEI first submitted an application for a permit in July 2007 and then submitted a revised air permit application in 2008. The Idaho Department of Environmental Quality issued the permit after a complete and thorough evaluation.

The Power County Advanced Energy Center will produce nitrogen based fertilizer to be used by the local agricultural economy. The feedstock is coal and petroleum coke that will be converted to syngas using GE gasification technology. The syngas will be converted to nitrogen based fertilizer. According to an April 2008 letter to the Idaho DEQ, the project will produce up to 500 tpd of anhydrous ammonia, up to 1,800 tpd of granular urea, and up to 1,600 tpd of ammonia nitrate. All of these products are used in the agricultural industry.

The plant site is located on 450 acres near American Falls, Idaho. The site is zoned heavy industrial and is next to the Lamb Weston Potato Processing Plant. Construction is estimated to be complete by 2012.
