Alliant Energy PowerHouse (formerlyFive Seasons Center and laterU.S. Cellular Center) is a multi-purposearena located in the downtown area ofCedar Rapids, Iowa. It was financed by the approval of a voter referendum to allocate special municipal capital improvement bond monies, after several prior bond referendums to build a civic center failed between 1965 and 1977. The initial construction cost was approximately $7 million for the arena and facilities. The city approved an additional $1 million to build an adjacent multi-level parking facility connected to the center by a skywalk. The center is adjoined by a 16-storyDoubleTree hotel facility built directly above the arena.

The center hosted local sporting events including the Iowa High School Girls State Volleyball Tournament until 2021 and the Iowa High School Boys State Wrestling Dual Championships until 2011. It was opened in 1979 as the Five Seasons Center and hosted the English progressive-rock bandYes as its first official concert event on April 25, 1979. The arena has a basketball capacity of about 6,900 and can seat up to 8,600 for concerts. It served as the primary sports and entertainment venue in Eastern Iowa until the completion ofCarver–Hawkeye Arena inIowa City four years later. Further more, with the opening ofXtream Arena in nearby Coralville (suburb of Iowa City), the venue has lost more events. Former professional tenants include the Cedar Rapids River Raiders of theUnited States Basketball League, the Cedar Rapids Sharpshooters of theGlobal Basketball Association and the Cedar Rapids Silver Bullets of theContinental Basketball Association. Numerous commencement ceremonies are held at the arena.
The venue hosted the initialWorld Championship Wrestling (WCW)Souled Out event in 1997. It also hosted WCW'sClash of the Champions XXVIII event in 1994 and a WCWMonday Nitro event in 1999. As the Five Seasons Center, it was the site of two earlyUltimate Fighting Championship events:UFC 21 in 1999, andUFC 26 the following year. One notable wrestling match in 1989 hadAndre the Giant arrested by police after attacking aKCRG-TV photographer filming the match. He was charged with assault and later acquitted, though he was still fined for criminal mischief and damage to KCRG's equipment.[2]
In early June 2008, the U.S. Cellular Center was flooded with water from theIowa flood of 2008.[3]
The arena closed in July 2011 to undergo renovations as part of a larger project to build a convention complex around the site, which also includes renovations to the new DoubleTree by Hilton Hotel. Events were diverted to other venues in the area, including theImOn Ice Arena (also managed by VenuWorks) and Carver-Hawkeye Arena, during that time. The complex was re-opened for a concert byLady Antebellum on June 1, 2013.[4] It was selected as the host arena for the NCAA Division II National Volleyball tournament December 12–14, 2013.
It was home to theCedar Rapids Titans/River Kings of theIndoor Football League from 2014 to 2019,[5] now ofAmerican Indoor Football since 2024.
On October 17, 2014, US Cellular Center held an NBA preseason game between theMilwaukee Bucks andMinnesota Timberwolves.[6]
The City of Cedar Rapids announced on October 23, 2020, that it had reached a naming rights agreement withAlliant Energy, the region's electricity provider, that took effect July 1 and lasts twelve years.[7]
