The station launched on the 12th of May 2000[2] with the South Coast and Adelaide Hills repeater licenses being granted on the 7th of March 2002[3] and 21st of October 2005[4] respectively. At this time, the station was owned by Grant Broadcasters.[5]
The Adelaide Hills and South Coast repeater stations were set up due to terrain coverage issues from the original 98.7 site on Gifford Hill for parts of the Adelaide Hills and along a majority of the Fleurieu Peninsula, areas that sister station 5MU, at that time on 1125kHz AM, was able to cover with ease and are also part of the Murray Bridge RA1 ACMA license area.[6] These repeaters run at 1kW ERP[3][4] each, supplementing the 20kW ERP[2] output from the Gifford Hill transmission site.
In November 2021, Power FM, along with other stations owned by Grant Broadcasters, were acquired by the Australian Radio Network. This deal will allow Grant's stations, including Power FM, to access ARN's iHeartRadio platform in regional areas. The deal was finalized on 4 January 2022.[7]
